  • Patent number: 7936866
    Abstract: Methods, systems, and computer program products for routing query messages associated with prepaid subscribers in a number portability environment are disclosed. One method may include sending a registration message to an HLR. At the HLR, the ID or address of an STP is inserted as the prepaid SCP ID in a registration response message. The registration response message is sent to the MSC/VLR that originated the registration message. This action forces the VLR to send prepaid query messages to the STP, rather than to the prepaid SCP. When the STP receives a query message relating to call originating from the prepaid subscriber, the STP performs a number portability database lookup and determines the routing number corresponding to the called subscriber and the prepaid SCP corresponding to the calling subscriber. The STP then routes the query message to the appropriate prepaid SCP.

  • Patent number: 7606219
    Abstract: In a telephone network, an intelligent peripheral (IP) provides a variety of auxiliary call processing functions, such as announcement playback and digit collection. In response to each call, the IP queries a service control point (SCP) over a data network, for instructions as to processing of the call. The IP runs software to select one SCP for control of each call, from a number of SCPs on the data network, and obtain the requisite instructions for the call from the identified SCP. For each call, the IP software identifies the telephone number of the subscriber and uses the NPA-NXX and D digits from that number to access a first mapping table and obtain a CLLI code identifying an SCP. Using the CLLI code from the first table, the IP software accesses a second mapping table to obtain the CLLI code for the mate to the identified SCP. Using the two CLLI codes, the IP also goes through the second table to obtain all of the Internet Protocol addresses for the two SCPs.

  • Patent number: 7471784
    Abstract: In accordance with an improved call routing methodology, a call is routed within a communication network by reference to one or more databases. In response to receiving a local number portability request at a service control point (SCP), the SCP accesses one or more databases to determine whether or not to apply custom call routing to a call directed to a called telecommunications number. In response to determining to apply custom call routing to the call, the SCP performs at least a second access to the one or more databases to obtain a local routing number (LRN) associated within the one or more databases with a calling telecommunications number associated with the call. The SCP thereafter provides the LRN to a service switch point in the communication network so that the call is routed to a called station associated with the called telecommunications number.

  • Patent number: 7386112
    Abstract: An originating node is configured for generating a route management signaling message having a signaling link selection (SLS) value that is selected by the originating node based on an affected destination value. The affected destination value, distinct from a destination point code (DPC) that specifies a destination node for the route management signaling message, identifies an affected signaling node that is affected by the route management signaling message. Hence, route management signaling messages related to the affected signaling node are routed along the same signaling path, ensuring that all the related route management signaling messages remain in sequence. Further, different signaling path can be established for respective affected signaling nodes, providing load sharing of route management signaling messages relative to the respective affected signaling nodes.

    Abstract: A call is routed to a wireless mobile station from a wireline network while bypassing a host mobile switching center (MSC) of the mobile station when the mobile station is registered at an MSC other than the host MSC. In particular, a service control point (SCP) in the wireline network receives a query from a tandem switch, associated with a trunk group of the host MSC, in response to an attempted termination of the call at the trunk group. Based on information from the query, the SCP retrieves registration data from a home location register of the host MSC, using IS-41 signaling. When the registration data indicates that the mobile station is registered at the alternate MSC, the SCP instructs the tandem switch to route the call directly to a trunk group of the alternate MSC, i.e., without passing through the host MSC.

  • Patent number: 7236582
    Abstract: A signaling transfer point (STP) (or Signaling Server Global (SSG)) is described herein which includes a processor and a mapping database that can depending on the direction of a message change the Origination Point Code (OPC) or the Destination Point Code (DPC) and the Circuit Identification Code (CIC) contained in the message. As such, the STP can receive a message from a foreign switch located in another telecommunications network and redirect the message that was originally destined for an old switch, which is in the process being removed or has been removed, to a new switch which now hosts the trunks previously connected to the old switch. The return traffic from the new switch is also processed by the STP so that when the foreign switch receives the message, it will appear like it originated from the old switch. As a result, the user of the STP can transparently consolidate switches without affecting the SS7 database contained in other carrier networks.

  • Patent number: 7184538
    Abstract: A communication network includes a Security Gatekeeper that authenticates and validates network control messages within, transiting, entering and leaving an overlying control fabric such as an SS7 network. The Security Gatekeeper incorporates several levels of checks to ensure that messages are properly authenticated, valid, and consistent with call progress and system status. In addition to message format, message content is checked to ensure that the originating node has the proper authority to send the message and to invoke the related functions and that the message, itself, is appropriately coded. Predefined sets of templates may be used to check the messages, each set of templates being associated with respective originating point codes and/or calling party addresses. The templates may also be associated with various system states such that messages corresponding to a particular template cause a state transition along a particular edge to a next state node for which another set of templates is defined.

  • Patent number: 7123710
    Abstract: Methods and systems for intelligent signaling-router-based surveillance are disclosed. A surveillance and signaling router receives call signaling messages, identifies call signaling messages associated with users under surveillance and determines a surveillance type for the call signaling messages. If the surveillance type is content-related, the surveillance and signaling router forwards the message to a call server. The call server replaces parameters in the message and in subsequent messages so that the call is transparently set up through a media proxy server. The media proxy server copies the media stream to a delivery function. If the surveillance type is non-content-related, the surveillance and signaling router sends a copy of the message or information extracted from the message to an external device.

  • Patent number: 7092388
    Abstract: A method and an apparatus of adding an application in a signal messaging network without adding a node in the network. An application platform is connected between two nodes by means of a first link and a second link. The application platform only comprises OSI stacks to layer 2 after which a link management and any possible application takes over. The link management will mirror the status of the two links to thereby keep the application platform unobtrusive, i.e. giving appearance of it not being connected between the two nodes.

  • Patent number: 7088728
    Abstract: Methods and systems for associating a plurality of different routes with the same destination and for routing signaling messages to the destination based on originating information associated with non-adjacent signaling nodes are disclosed. A routing database in a signal transfer point includes multiple routes to the same destination. The routes are distinguishable from each other in the routing database using message origination information associated with signaling nodes that are not adjacent to the signal transfer point. When a signaling message is received, origination and destination information in the signaling message are used in combination to select among multiple routes to a destination having a network address corresponding to the destination information in the signaling message. The signaling message is then routed over the route selected using the originating information. The selected route may be a high-speed route used to provide a particular quality of service.

  • Patent number: 7072678
    Abstract: Methods and systems for triggerless mobile group dialing are disclosed. A method for triggerless mobile group dialing includes intercepting call signaling messages that contain mobile dialing codes. For these call signaling messages, a mobile dialing group ID is determined based on the calling party address in the mobile call signaling messages if the mobile call signaling messages contain calling party addresses. The mobile dialing group ID and the mobile dialing code are used together to determine a full called party address for each of the signaling messages. In lieu of using a mobile dialing group ID, a method is also presented for directly associating combinations of full E.164 calling party address digits and mobile dialing codes to full E.164 called party address digits. The full called party address is inserted in each of the signaling messages and each message is routed to its intended destination.

  • Patent number: 7035391
    Abstract: Communication between a service switching point (SSP) and an external (or stand alone) Intelligent Peripheral (IP) has not been defined by any of the standard bodies. ITU-T Q.1600 and ETSI 300 374-1 defines the network configuration of SCP, SSP and stand-alone IP units using SS7 ISUP connection, but ITU-T Q.1600 and ETSI 300 374-1 does not specify in detail the SS7 ISUP messages for bi-directional communication between a SSP and an IP unit. This invention details the message flow between a SCP, a SSP and an ISUP IP unit, especially in the messages between the SSP and IP unit using SS7 ISUP protocol. With the signaling method of the present invention, SCP can send INAP operations, such as PA, PCUI to instruct an external IP unit to play an announcement or collect user information, then an IP unit can send back the related operations back to SCP. In this case, the resource of the IP unit can be shared by other switches and SSPs in the network.
