The field of the invention relates to a method of processing data for at least one wireless communication network, and a data processing system therefor.
BACKGROUND OF THE INVENTIONWireless communication systems, such as the 3rd Generation (3G) of mobile telephone standards and technology, are well known. An example of such 3G standards and technology is the Universal Mobile Telecommunications System (UMTS™), developed by the 3rd Generation Partnership Project (3GPP™) (www.3gpp.org).
The 3rd and 4th generations of wireless communications, and particular systems such as LTE (Long Term Evolution), have generally been developed to support macro-cell mobile phone communications, and more recently femto-cell mobile phone communications. Here the ‘phone’ may be a smart phone, or another mobile or portable communication unit that is linked wirelessly to a network through which calls etc. are connected. Henceforth all these devices will be referred to as mobile communication units. Calls may be data, video, or voice calls, or a combination of these. An increasing proportion of communications involve data rather than voice, and are technically referred to as being a ‘connection’, rather than a ‘call’. Nevertheless, the terms ‘connection’ and ‘call’ as used herein are to be understood as being interchangeable and each referring to data, video and/or voice calls/connections unless otherwise defined.
Typically, mobile communication units, or User Equipment as they are often referred to in 3G parlance, communicate with a Core Network of the 3G (or 4G) wireless communication system. This communication is via a Radio Network Subsystem. A wireless communication system typically comprises a plurality of Radio Network Subsystems. Each Radio Network Subsystem comprises one or more cells, to which mobile communication units may attach, and thereby connect to the network. A base station may serve a cell. Each base station may have multiple antennas, each of which serves one sector of the cell.
Operators of wireless communication systems need to know what is happening in the system, with as much precision as possible. A particular issue is the need to solve ‘faults’. Faults may take a wide variety of forms, but can be summarised as events when the network and/or one or more mobile communication units do not perform as expected.
In most conventional wireless networks, quality of service information is generally reported on a per-cell or per-sector basis. A result of this is that network statistics obtained may only provide an indication of the average data rate or average number of dropped calls, for example, in a given sector or cell. It is not usually possible to obtain network statistics from such conventional quality of service information for a particular portion of a sector or cell that may suffer from poor data rates or dropped calls due, in part, to these particular sectors or cells having poor coverage.
It is known to utilise and compare, in real time, the signatures of mobile communication units to determine location information. These systems are typically located at, for example, switching centres where raw communication session data is stored. Modern wireless communication systems allow a high degree of autonomy to individual mobile communication units and to base stations. As a consequence, decisions about setting up and ‘tearing down’ call links throughout the network are not all made centrally. As a result, a complication arises from the volume of raw communication session data generated within the wireless communication system. In one day, a wireless communication system may generate 100 gigabytes of data about calls that have been made in the network.
One constraint in particular is the processing requirements for processing the large volumes of raw data in order to obtain meaningful information. With conventional systems, which are typically located at, for example, switching centres where raw communication session data is stored, significant processing resources are required to be provided at each such location (e.g. at each switching centre) for processing the ‘local’ data stored at the respective location.
Such a distribution of processing resources across multiple locations within a network, with the processing resources at each location being dedicated to the processing of local data, is an inefficient use of such processing resources since often the processing resources at many of the locations may not be fully utilised. Furthermore, if the processing requirements at a particular location are increased, for example due to an increase in network capacity corresponding to that location, the processing capacity at that location may be exceeded even if only by a small amount. As a result, additional processing hardware may need to be sourced. Such a small additional processing requirement could require replacement or additional sets of processing cards, racks or storage to be implemented. In this case, a relatively large capital outlay may be required by the network operator to provide for a relatively small increase in required processing capacity.
A conventional approach to improve efficiency in mass processing systems is to provide the data to be processed to one or more centralised or shared processing resources. For example, data from distributed sites (e.g. the switching centres of a wireless communication system) may be provided to centralised processing resources or to one or more shared (e.g. cloud) processing resources. In this manner, more efficient processing of data from multiple distributed sites may be performed.
Another important requirement for the Applicant's data processing system is that users are able to access data in near real time. For example, data relating to an event is available to users within a relatively short period of time, for example within, say, a couple of minutes of the data being made available from the radio network controller (RNC), in a 3G (or 4G) wireless communication system. It is worth noting that in a conventional 3G/4G wireless communication system, data relating to recent calls is made available by RNCs in batches, for example comprising 15 minutes worth of call data. As such, data may be made available by an RNC approximately every 15 minutes, with a potential 15 minute latency for some of the call data between the respective event and the data being made available by the RNC. Because of this inherent 15 minute latency between an event occurring and the data being made available by the RNC, it is even more important to minimise any further delay between the data being made available by the RNC and the data being available to users.
This is in contrast to conventional data processing systems which perform ‘batch processing’ whereby data is processed off-line, and there is a delay of many hours typically between an event of interest taking place and the resulting diagnostic information being available to users. Furthermore, a relatively large number of users may be required to access data substantially simultaneously. As such, not only is there a requirement for data to be processed efficiently in terms of cost, but also in terms of enabling near real time access of data by multiple users.
Thus there is a need for an improved method and apparatus for processing data within a wireless communication network.
SUMMARY OF THE INVENTIONAccordingly, the invention seeks to mitigate, alleviate or eliminate one or more of the abovementioned disadvantages singly or in any combination.
According to a first aspect of the present invention, there is provided a method of processing data for at least one wireless communication network. The method comprises determining geolocation information for data segments received at a plurality of distributed components of a data processing system, the data segments being received from at least one network element of the wireless communication network, and forwarding the data segments to backend processing resources based at least partly on their respective geolocation information.
In this manner, data to be processed may be ‘sharded’ based on the geolocation information of the data segments, and allocated to backend processing resources accordingly. Advantageously, because wireless communication network data queries typically relate to data corresponding to particular geographical locations/regions, geographically sharding the data in the manner described enables the data to be allocated across a relatively large number of relatively small processing resources whilst still enabling queries to be serviced by a single (or few) processing resources. This enables a significant amount of parallelism to be implemented within the data processing system, significantly speeding up the processing of data, thereby facilitating the near-real-time access of data by users. Furthermore, by facilitating the use of relatively small processing resources in this manner, additional processing resources can be added in relatively small increments, enabling a more cost effective manner of increasing (or decreasing) processing capabilities as required.
According to a second aspect of the present invention, there is provided a data processing system for processing data from at least one wireless communication network. The data processing system comprising at least one allocation component arranged to determine geolocation information for data segments received at a plurality of distributed components of a data processing system, the data segments being received from at least one network element of the wireless communication network, and forward the data segments to backend processing resources based at least partly on their respective geolocation information.

The allocation component being arranged to determine geolocation information for data segments received at a plurality of distributed components of a data processing system, the data segments being received from at least one network element of the wireless communication network, and forward the data segments to backend processing resources based at least partly on their respective geolocation information.
According to a fourth aspect of the present invention, there is provided a distributed component of a data processing system for processing data from at least one wireless communication network. The distributed component of the data processing system being arranged to receive data from at least one network element of the wireless communication network, determine geolocation information for data segments within the received data, and forward data segments within the received data to backend processing resources based at least partly on their respective geolocation information.
According to a fifth aspect of the present invention, there is provided a non-transitory computer program product having computer-readable code stored thereon for programming a data processing module to perform the method of the first aspect of the present invention.

The data processing system 100 comprises a plurality of distributed components 110, each distributed component 100 arranged to receive data from one or more network elements 112. In the example illustrated in
The data processing system 100 further comprises backend processing resources, indicated generally at 120. In the illustrated example, the backend processing resources comprise a plurality of database servers 122 arranged to receive data from the distributed components 110 and perform, for example, pre-processing of the received data to enable efficient storage and access of the received data. In the illustrated example, each database server 122 is operably coupled to one or more data storage devices 124 in which the pre-processed data may be stored, for example for subsequent processing to generate statistical data for the wireless communication network. The backend processing resources 120 may further be arranged to perform near-real-time processing of the stored, pre-processed data in response to requests from client applications. As such, in the illustrated example the backend processing resources 120 are operably coupled to one or more client servers 130 through which users operating user terminals 135 are able to access data stored within data storage devices 124. Examples of the contemplated functionality of the database server 122 are described in the Applicant's co-pending U.S. patent applications: U.S. patent application Ser. No. 13/849,245; U.S. patent application Ser. No. 13/849,262; and U.S. patent application Ser. No. 13/849,279, all of which are incorporated by reference herein.

The method starts at 210 and moves on to step 220 where, in the illustrated example, index values are assigned to predefined geographical regions. For example, and as illustrated in
The geographical regions are each assigned an index value, for example such as a simple index number as indicated at 400 in
Having assigned index values to the predefined geographical regions, the method moves on to step 230 where predefined geographical regions are allocated to backend processing resources. The method may comprise allocating backend processing resources to predefined geographical regions based on any suitable parameters such as anticipated volumes of data for individual geographical regions, processing capacities of backend processing resources, etc. In this manner, the distribution of the required processing of data may be allocated across the backend processing resources in such a manner as to evenly distribute the processing load across the backend processing resources relative to the processing capabilities of the individual backend processing resources.
In some examples, such as the example herein described, it is contemplated that geographical regions of substantially equal size may be defined. As such, the volumes of data for individual geographical regions will vary significantly. For example, primarily rural geographical regions will typical comprise significantly smaller volumes of data than, say, inner city geographical regions. In this manner, the allocation of geographical regions to backend processing resources may be implemented to take into account such variations in volumes of traffic between geographical regions.
In some alternative examples it is contemplated that geographical regions may alternatively be defined in order to achieve a substantially uniform anticipated volume of traffic within each geographical region. In this manner, a substantially even allocation of geographical regions to backend processing resources may be implemented.
In the illustrated example, once the geographical regions have been allocated to backend processing resources, the method moves on to step 240 where the backend processing resources are associated with the index values assigned to the predefined geographical regions allocated thereto. For example, five database servers 122 are illustrated in
In the example illustrated in Table 1, four geographical regions have been assigned to database server A, whilst two geographical regions have been assigned to each of database servers B, C and E and a single geographical region has been assigned to database server D. Four geographical regions may have been assigned to database server A due to, say, those four regions having relatively low anticipated volumes of data and/or database server A comprising relatively high processing and/or storage capabilities. Conversely, only a single geographical region may have been assigned to database server D due to that geographical region comprising a relatively high anticipated volume of data and/or database server D comprising a relatively low processing and/or storage capability. In this way, overloading and/or underutilisation of backend processing resources may be substantially avoided, with each processing its data independently of the others (i.e. in parallel). This use of parallel processing, together with appropriate allocation of data to backend processing resources leads to a suitably fast response time for the users whilst utilising affordable (and easily expanded) hardware.
Advantageously, by allocating backend resources on a geographical basis as described above enables geographical based queries to be handled more efficiently. For example, if the backend processing resources were allocated in a non-geographical basis, for example ‘on the fly’ with each item to be processed being allocated to the least busy (or full) processor/server, geographic based queries would need to fetch data from a huge number of locations across a number of servers, greatly reducing access speeds to the required data and hence greatly slowing the fulfilment of the query. The present invention takes advantage of the fact that the volumes of data generated by each geographic region are typically predictable and also relatively invariant (the ‘average’ daily populations, both static and mobile, of each region will typically not change quickly over time) and hence allocation by geography is a good way of allocating processing/storage resources, without undue wastage.
Having associated backend processing resources with the index values assigned to the predefined geographical regions allocated thereto, the method moves on to step 250 where one or more data allocation components, such as those illustrated at 150 in

The raw, unprocessed data from the RNCs 112 represents a huge amount of information that would require a very high speed, and very expensive, communications link in order to transport the data to backend processing resources. Accordingly, in the illustrated example, a subset of the received (raw) data to be forwarded to the backend processing resources is extracted at 340. For example, only those data elements needed in most or all cases by data processing algorithms may be extracted from the received (raw) data. For example, in the case where the raw data received comprises ‘layer 3’ network information, the data elements extracted for forwarding to the backend processing may comprise:
-
- session connection setup information;
- session closedown information;
- identification of radio links involved in session;
- measured radio propagation delay;
- radio bearer or bearers involved during session;
- type of session;
- measurement reports;
- received signal code power;
- subscriber information;
- etc.
By extracting only a subset of the raw data for forwarding to the backend data processing in this manner, a reduced bandwidth may be used to forward such data to the backend processing resources.
Geolocation information is then determined at 350 for data segments within the extracted subset of the received data. Geolocation is the identification of the real-world geographical location of an object, such as a mobile communication unit. Geolocation techniques are well known in the art, and as such need not be described in any greater detail herein. Nevertheless, one example implementation of geolocation is described in the Applicant's co-pending International Patent Application No. WO 2010/081658 entitled “GEO-LOCATION IN A WIRELESS COMMUNICATION NETWORK” which is herein incorporated by reference.
Next, at step 360, the geolocation information determined at step 350 is used to identify to which predefined geographical regions the individual data segments within the extracted subset of received data relate. The data segments are then forwarded to backend processing resources associated with index values of their respective identified geographical regions, at step 370.
For example, based on Table 1 above: data segments that have been identified as relating to the geographical regions to which index values 1 to 4 have been assigned would be forwarded to database server A; data segments that have been identified as relating to the geographical regions to which index values 5 and 6 have been assigned would be forwarded to database server B; data segments that have been identified as relating to the geographical regions to which index values 7 and 8 have been assigned would be forwarded to database server C, etc. It will be appreciated that, by allocating backend processing resources to predefined geographical regions based on parameters such as anticipated volumes of data for individual geographical regions, processing capacities of backend processing resources, etc., and then forwarding the data segments within the received data to backend processing resources based on their respective geolocation information, the data segments are effectively forwarded to backend processing resourced based on those parameters (i.e. anticipated volumes of data for individual geographical regions, processing capacities of backend processing resources, etc.).
In the example illustrated in
In this manner, data to be processed is ‘sharded’ based on the geolocation information of the data segments, and allocated to backend processing resources accordingly. Advantageously, because wireless communication network data queries typically relate to data corresponding to particular geographical locations/regions, geographically sharding the data in the manner described enables the data to be allocated across a relatively large number of relatively small processing resources whilst still enabling queries to be serviced by a single (or few) processing resources. This enables a significant amount of parallelism to be implemented within the data processing system, significantly speeding up the processing of data, thereby facilitating the near-real-time access of data by users. Furthermore, by enabling the use of relatively small processing resources in this manner, additional processing resources can be added in relatively small increments, enabling a more cost effective manner of increasing (or decreasing) processing capabilities as required.
Thus, in accordance with some examples of the present invention, it is proposed that a large number of small, low-cost, processing and storage elements are used to provide the backend processing resources. It will be appreciated that the backend processing resource hardware may in some examples be co-located with one or more of the MSCs 110 hardware, or a similar location. Equally, it may be located in a separate (operator-owned or third-party) data centre.
As will be appreciated by a skilled person, data is typically received by the MSCs 110 as a substantially continuous stream of data from the RNCs 112. As such, for some examples of the present invention the method steps of

Computing system 600 can also include a main memory 608, such as random access memory (RAM) or other dynamic memory, for storing information and instructions to be executed by processor 604. Main memory 608 also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by processor 604. Computing system 600 may likewise include a read only memory (ROM) or other static storage device coupled to bus 602 for storing static information and instructions for processor 604.
The computing system 600 may also include information storage system 610, which may include, for example, a media drive 612 and a removable storage interface 620. The media drive 612 may include a drive or other mechanism to support fixed or removable storage media, such as a hard disk drive, a floppy disk drive, a magnetic tape drive, an optical disk drive, a compact disc (CD) or digital video drive (DVD) read or write drive (R or RW), or other removable or fixed media drive. Storage media 618 may include, for example, a hard disk, floppy disk, magnetic tape, optical disk, CD or DVD, or other fixed or removable medium that is read by and written to by media drive 612. As these examples illustrate, the storage media 618 may include a computer-readable storage medium having particular computer software or data stored therein.
In alternative embodiments, information storage system 610 may include other similar components for allowing computer programs or other instructions or data to be loaded into computing system 600. Such components may include, for example, a removable storage unit 622 and an interface 620, such as a program cartridge and cartridge interface, a removable memory (for example, a flash memory or other removable memory module) and memory slot, and other removable storage units 622 and interfaces 620 that allow software and data to be transferred from the removable storage unit 618 to computing system 600.
Computing system 600 can also include a communications interface 624. Communications interface 624 can be used to allow software and data to be transferred between computing system 600 and external devices. Examples of communications interface 624 can include a modem, a network interface (such as an Ethernet or other NIC card), a communications port (such as for example, a universal serial bus (USB) port), a PCMCIA slot and card, etc. Software and data transferred via communications interface 624 are in the form of signals which can be electronic, electromagnetic, and optical or other signals capable of being received by communications interface 624. These signals are provided to communications interface 624 via a channel 628. This channel 628 may carry signals and may be implemented using a wireless medium, wire or cable, fibre optics, or other communications medium. Some examples of a channel include a phone line, a wireless phone link, an RF link, a network interface, a local or wide area network, and other communications channels.
In this document, the terms ‘computer program product’ ‘computer-readable medium’ and the like may be used generally to refer to media such as, for example, memory 608 storage device 618 or storage unit 622. These and other forms of computer-readable media may store one or more instructions for use by processor 604, to cause the processor to perform specified operations. Such instructions, generally referred to as ‘computer program code’ (which may be grouped in the form of computer programs or other groupings), when executed, enable the computing system 600 to perform functions of embodiments of the present invention. Note that the code may directly cause the processor to perform specified operations, be compiled to do so, and/or be combined with other software, hardware, and/or firmware elements (e.g. libraries for performing standard functions) to do so.
As used herein, the expression non-transitory will be understood to refer to the non-ephemeral nature of the storage medium itself rather than to a notion of how long the stored information itself may persist in a stored state. Accordingly, memories that might otherwise be viewed, for example, as being volatile (such as many electronically-erasable programmable read-only memories (EPROM's) or random-access memories (RAM's)) are nevertheless to be viewed here as being “non-transitory” whereas a signal carrier in transit is to be considered “transitory” notwithstanding that the signal may remain in transit for a lengthy period of time.
In an embodiment where the elements are implemented using software, the software may be stored in a computer-readable medium and loaded into computing system 600 using, for example, removable storage drive 622, drive 612 or communications interface 624. The control module (in this example, software instructions or computer program code), when executed by the processor 604, causes the processor 604 to perform the functions of the invention as described herein.
Furthermore, the inventive concept can be applied to any signal processing circuit. It is further envisaged that, for example, a semiconductor manufacturer may employ the inventive concept in a design of a stand-alone device, such as a microcontroller, digital signal processor, or application-specific integrated circuit (ASIC) and/or any other sub-system element.
It will be appreciated that, for clarity purposes, the above description has described embodiments of the invention with reference to different functional units and processors. However, it will be apparent that any suitable distribution of functionality between different functional units or processors may be used without detracting from the invention. For example, functionality illustrated to be performed by the same processor or controller may be performed by separate processors or controllers. Hence, references to specific functional units are only to be seen as references to suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organization.
Because the illustrated embodiments of the present invention may for the most part, be implemented using electronic components and circuits known to those skilled in the art, details will not be explained in any greater extent than that considered necessary as illustrated above, for the understanding and appreciation of the underlying concepts of the present invention and in order not to obfuscate or distract from the teachings of the present invention.
In the foregoing specification, the invention has been described with reference to specific examples of embodiments of the invention. It will, however, be evident that various modifications and changes may be made therein without departing from the broader spirit and scope of the invention as set forth in the appended claims. Other modifications, variations and alternatives are also possible. The specifications and drawings are, accordingly, to be regarded in an illustrative rather than in a restrictive sense.
In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word ‘comprising’ does not exclude the presence of other elements or steps then those listed in a claim. Furthermore, the terms “a” or “an,” as used herein, are defined as one or more than one. Also, the use of introductory phrases such as “at least one” and “one or more” in the claims should not be construed to imply that the introduction of another claim element by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim element to inventions containing only one such element, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an.” The same holds true for the use of definite articles. Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage.
