Signalling Path Distinct From Trunk (e.g., Ccis) Patents (Class 379/230)
  • Patent number: 9749296
    Abstract: Contact information in SIP signaling messages is modified at each in-path network device during the signaling process (along with storage of mapping information) to allow the in-path network devices (and proxy server) to identify the next (or previous) hop device in the path, and thus, maintain the path taken by signaling messages early on during the signaling process. Subsequent request and response signaling messages transmitted during the session follow this path, which ensures that the in-path network devices remain in the SIP signaling path.

To establish a communication session, an originating gateway sends one or more initial call control messages using overlap signaling to a destination gateway. The destination gateway may be unable to establish the communication session using overlap signaling. The destination gateway signals the originating gateway, such as by indicating that the communication session could not be established because of an incomplete or invalid destination address. The originating gateway then attempts to establish the communication session using en bloc signaling. In this way, an attempt that fails due to the use of overlap signaling is retried using en bloc signaling.

    Abstract: A method for determining the name of a calling party where the calling party's name and corresponding telephone number are found in a remote database. The method first identifies whether the calling party's telephone number is contained within the local database. When it is determined that the telephone number is not within the local database, the method attempts to locate the telephone number in a remote database. A query is formed according to a basic signal transmission protocol to ensure that a database which receives the query will be able to respond to it. The query requesting the name associated with the telephone number is sent across a network. The method receives a response to the inquiry and checks to ensure that a name was returned to the local database before delivering the name to the called party.

  • Patent number: 7835513
    Abstract: A telecommunications node (e.g., signalling transfer point) and method are described herein that implement a synthetic GTT transformation function which allows a direct address SCCP message received from a legacy switch to be transformed into a GTA SCCP message that can be propagated to another switch (located in the same network or in a different network) which requires the use of a GTT functionality. In turn, the telecommunications node and method can also provide the reverse capability as a SCCP message comes back to the legacy switch.

  • Patent number: 7760706
    Abstract: Methods and systems for load sharing signaling messages at the MTP level are disclosed. When a signaling message is received, it is determined whether the signaling message includes a routing indication indicating route-on-point-code-subsystem-number. If the routing indicator indicates route-on-point-code-subsystem-number, it is determined whether the signaling message belongs to an MTP level 3 load sharing group. If the signaling message belongs to an MTP level 3 load sharing group, the signaling message may be routed to any of the point codes in the MTP level 3 load sharing group. Routing the signaling message to a point code in the MTP level 3 load sharing group may include replacing the destination point code in the signaling message with the destination point code of the node to which the signaling message is to be routed. Once the point code has been replaced, the signaling message is routed to the destination associated with the point code.

  • Patent number: 7701927
    Abstract: The invention relates to a method for transmitting communication data in a communication system (CSY) between a calling first communication unit (IPPA) and a called second communication unit (IPPD), wherein, in a first step a primary connection is set up starting from the first communication unit (IPPA) via at least one node unit to the second communication unit (IPPD) with transmission of addressing data of the communication units (IPPA,IPPD) and node units participating in the setup of the primary connection. Following this, the first communication unit (IPPA) and/or a first node unit disposed along the primary connection which have a valid addressing data element are registered as the ingress node. Furthermore, the second communication unit (IPPD) and/or a last node unit disposed along the primary connection which have a valid addressing data element are registered as the egress node.

  • Patent number: 7664247
    Abstract: Methods and apparatus for providing automatic route selection (ARS) services through the use of advanced intelligent network (AIN) functionality are described. AIN based ARS services are provided through the use of a route selection table implemented outside a switch, e.g., at the service control point (SCP). Alternatively, ARS functionality is provided using conditional logic at the SCP or a combination of conditional logic and an ARS table. The AIN based ARS service can be provided in addition to switch based ARS services. Methods for selecting the ARS method to be used based on switch type and/or the complexity of the ARS service to be provided are also described. The ARS functionality identifies the route, e.g., physical trunk or other line, over which a call is to be routed. The selection may be between trunks corresponding to different telecommunications carriers, services or privately owned lines.

  • Patent number: RE41221
    Abstract: System and method for providing a customer with the ability to obtain temporary advanced telecommunication services in the Advanced Intelligent Network (AIN) for the customer's calling line by dialing a call to special access code, without the intervention of a service representative. The call is recognized as a request for an initiation of a temporary advanced telecommunication service with respect to the customer's calling line. On the basis of the recognition, an association may be retained between the calling line number and the service switching point serving the calling line number. This retained association may be used later in the activation of the temporary advanced telecommunication service for the calling line number. The call is routed to a rental service interface through which rental information from the caller may be collected.
