Abstract: A method and apparatus for packet-data header decompression, particularly advantageous for use in connection with broadcast and multicast messages being transported through a radio telecommunication system operable according to the CDMA 2000 standard. When a mobile subscriber desires broadcast content from a content server, the mobile station sets up a PPP session for submitting the request and negotiating security protocols. When a subscription is granted, the mobile station receives broadcast content that has undergone header compression. In order to synchronize its decompressor, the mobile station receives a full header from a PDSN. The full header is preferably sent out on a periodic basis just for this purpose.

Abstract: The present invention relates to a method and network node for controlling packet flow in a buffer means (13; 14) of a network node of a data network, wherein a nominal capacity is assigned to each data flow, and an additional or free capacity is shifted from a first flow portion to a second flow portion when a new data packet of said second flow portion has been received and said nominal capacity has been exceeded. The nominal capacity may be an upper buffer memory limit used for controlling queuing of data packets in a buffer memory (13) of said buffer means, wherein the memory space of the buffer memory (13) is shared between a plurality of channels allocated to respective packet data connections. Then, the free capacity corresponds to a memory space shifted from a first channel to a second channel, when a new data packet of the second channel has been received and not enough memory space is available for the second channel.

Abstract: Apparatus, and an associated method, facilitates authentication of a mobile station operable in a 3G cellular communication system having a core network and a plurality of access networks. A standard signaling protocol is used to communicate between an access network and the core network. When a request for authentication of a mobile station is generated, a signaling protocol message is generated at a proxy of the access network within which the mobile station is to be authenticated. Detection of the authentication request is made at the proxy, and a message is generated at the proxy which includes indicia associated with the authentication center associated with the access network. The signaling protocol message is sent to the core network, and the information indicia contained therein is used to facilitate authentication procedures to authenticate the mobile station.

Abstract: An accelerated slow-start enables fast recovery from a packet delay or loss condition or even from a deliberate suspension of service in an Internet connection in which a wireless link exists between a sending mobile host (30) and a receiving network host (40).

Abstract: The link layer (68, 64) of the sending end of a wireless link (66) is enhanced (10, 74) by providing a mechanism for discriminating (36, 38; 79, 82) between special, critical or otherwise important packets from among a plurality of packets send over the wireless link. Special link layer treatment (42; 89) is accorded to such special, critical or otherwise important packets, while the remaining packets are subjected to normal link layer treatment (44; 86) before transmission over the wireless link.

Abstract: A scheme for providing mobility management for terminals with multiple subscriptions. The invention integrates Europe's Universal Mobile Telecommunications Standard (UMTS) subscriber identity module—specific procedures into single procedures, and which uses a common TMSI. An UMTS subscriber identity module is allocated for each subscription associated with a mobile terminal, wherein each UMTS subscriber identity module being identified by a identification code. A location area update is performed by providing a single location area update request message comprising a list of identification codes for each UMTS subscriber identity module associated with the mobile terminal. Each USIM is authenticated separately, and some USIMs may fail, while others may succeed authentication. The terminal and network each build their own Ordered List of Registered USIM-IDs (OLRU) which records the USIMs that succeeded. The network assigns a Base TMSI, which is similar to the current assignment of TMSIs.

Abstract: A method and apparatus for eliminating the inefficient use of network bandwidth cause by numerous acknowledgment transmitted by the receiver to the transmitter by providing sparse feedback from the receiver to the transmitter indicating receipt of packets having headers to be used as reference headers. In the invention, upon receipt in the receiver of a packet having a reference header, a feedback is provided to the transmitter indicating receipt of the packet having the reference header. Thereafter, the receiver waits a predetermined period of time before providing another feedback in response to another packet having a reference header. The predetermined period of time allows time for the feedback to be received by the transmitter and for information from the transmitter indicating receipt of the feedback to be received by the receiver.

Abstract: A method, a system, or an article of manufacture provides Mobility Management (MM), for example, an update procedure, in a Core Network (CN) of a mobile communication system. The Mobile Station (MS) includes an indicator which defines an update type. The update type includes: all CN entities; one type of CN entity only. If the indicator has the update type of all CN entities, the MS registers all CN entities. If the indicator has the update type of one type of CN entity only, the MS registers the one type of CN entity only. The CN entities may be MSC/NVLR CN entity, SGSN CN entity, or other CN entity. The method includes the MS determining to which of the CN entity to perform the update procedure; the MS updating the CN entity; the CN acknowledging the MS whether update is successful or failed; and the CN acknowledging the MS whether update of other CN entity is needed, if needed, the CN defining to which of the CN entity to perform update, and continuing the update of the defined CN entity.

When converted, the informational content of the multimedia information is transmitted in a manner that achieves spectral efficiency and low, constant delay. Once transmitted over the radio channel, the multimedia information is converted back into form corresponding to the RTP protocol before being sent to the receiving station.

Abstract: Apparatus, and an associated method, for selectably deleting contents stored at a dictionary device of a sending or receiving entity. The dictionary device stores content representative of indicia associated with SIP, or other, signal protocol messages generated during operation of a communication system. A selector selects portions of the contents stored at the dictionary device to be deleted, thereby to permit additional content to be stored at the dictionary device. When separate dictionary devices are positioned at sending and receiving entities, implicit synchronous operation of selection of deletion of content at the separate dictionary devices is effectuated synchronously, but implicitly.

Abstract: The present invention relates to a method and system for providing a service in a communication network. A service script is used to control a service execution functional unit to execute the service, wherein an execution priority is allocated to the service script based on the kind of service. Furthermore, a service logic of the service may be provided at a service execution functional unit, and the service script may comprise a service description of the service. The service execution functional unit is then controlled based on the service description to execute the service by using the service logic. Thus, the service script does not contain the service logic, and a flexible service script concept can be provided. Moreover, the signaling traffic can be reduced since the operator does not have to update service scripts for a large amount of subscribers.

Abstract: The invention relates to a service control device and method for controlling service execution in a communication network. A service script for a user is loaded in response to the receipt of an incoming message, and it is checked based on a comparison of the loaded service script and the incoming message whether a service is to be triggered. If a service triggering has been determined, a service is activated in an external service execution environment. Due to the fact that the service execution is not performed in the service control point but in an external service execution environment, the service logic does not have to be provided at the service control point. It provides a flexible way to define, execute, and control user-specific, operator, and third party services combining various service capabilities.

Abstract: A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity.

Abstract: A method for scheduling data packets from a plurality of flows into a single flow. Data packets are broken into data segments and assigned a slack value based on how long the segment can wait until transmission begins. Every time a transmission opportunity passes, the slack value of the segment is decreased. The scheduler prioritizes the segments based on their slack value.
