Switching Network Having Separate Elements To Handle Circuit Switched Traffic And Packet Switched Traffic Patents (Class 370/354)
  • Patent number: 8625582
    Abstract: A communication system is provided that routes a bearer path of a communication session between an originating Node B and a terminating Node B via an X2 interface, bypassing an IMS core network, while continuing to route the signaling path to an IMS network, thereby allowing the IMS network to retain control of the bearer path while avoiding delay, potential for data loss and jitter to the bearer stream, and additional backhaul capacity requirements that result from routing the bearer path between the originating and terminating Node Bs via the IMS core network. In determining whether the bearer path may bypass the IMS core network, the communication system determines whether IMS core network bearer associated services are required for the communication session such that a bearer path of the call will need to be routed to the IMS core network in order to provide such services.

    Abstract: A mechanism for managing and enhancing communication streams in a VOIP service using SIP is discussed. SIP is used to manage and enhance a communication stream at a centralized switching element in the VoIP environment rather than at the communication stream endpoints. The communication stream set up by SIP is directed through a central switching element under administrative control rather than traveling directly between the stream endpoints. As a result, the media stream may be conditioned with treatments and may be provided with enhanced services at the central switching element without the specific treatments and services being supported at both stream endpoints. The use of the centralized switching element allows full administrative control of the VoIP environment.

    Abstract: Embodiments of the invention are directed to multicasting packets in a system such as a data packet switch or router having a distributed architecture. A first device such as a line card receiving a packet that requires multicasting forwards the packet to a fabric switch where the packet is replicated to obtain one respective packet for each line card of the system. Each line card receives its respective packet from the fabric switch and further duplicates the packet to obtain a duplicate packet for each egress endpoint of a service associated with the packet that is eligible to receive such a duplicate packet. Replication and duplication of packets requiring multicasting performed in this manner efficiently uses bandwidth of the fabric switch and links connecting it to the line cards.

  • Patent number: 8537817
    Abstract: In one embodiment, a Link State Advertisement (LSA) is received from a first router in a network at a second router in the network. The LSA advertises an address of an interface of the first router. The second router determines whether the LSA includes a transit-only identification that indicates the interface of the first router is a transit-only interface. If the LSA does not include a transit-only identification, the second router installs the advertised address of the interface of the first router in a Router Information Base (RIB) of the second router. If the LSA does include a transit-only identification, the second router declines to install the advertised address of the interface of the first router in the RIB of the second router.

  • Patent number: 8532091
    Abstract: The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminals being not adapted to provide IMS services to the users. In particular, it is proposed, in order to allow IMS to take the full call and service control, to place a user agent being responsible for the user ported to the IMS in a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of IMS. The invention discusses a concept of a static MAGCF being deployed in a network and being assigned for handling a user.

  • Patent number: 8532055
    Abstract: Apparatus, and an associated method, for facilitating routing of data in a packet radio communication system. A clone list is downloaded to the mobile node and stored at a clone list depository thereat. The clone list includes a plurality of entries, each of which provides routing information needed to route data when the mobile node is positioned within coverage areas encompassed by differing networks. A determination is made whether the clone list includes appropriate routing information to route a data packet sent by the mobile node positioned in a particular area encompassed by a particular network portion. If the clone list includes an entry containing such information, the need separately to request such information is obviated.

  • Patent number: 8516055
    Abstract: A system and method for redirecting data from a host system (or messaging server) to one or more mobile data communication devices via a wireless packet data network is provided in which the wireless packet data network dynamically assigns addresses to the one or more mobile data communication devices on an as-needed basis. A redirector application operating at the host system is configured by each user to continuously redirect certain data to the wireless packet data network, as the data is received (or otherwise altered) at the host system. Two methods are provided for communicating the redirected data from the network to the mobile device. In a first method, the mobile device is configured to periodically contact a store-and-forward server within the wireless network, which, when contacted, assigns a network address to the mobile device and then transmits the stored, redirected data to the mobile device.

  • Patent number: 8509152
    Abstract: A method of routing a wireless network is provided. The method is performed by each of a group of nodes and includes: receiving a routing request signal; determining whether a node itself is a destination node, by referring to a traffic distribution table showing traffic throughput of the group of nodes and an intermediate-node weight table showing weights of intermediate nodes on all paths between the group of nodes and a source node, wherein a route path is selected by referring to the weights of intermediate nodes; and when it is determined that the node itself is the destination node transmitting a routing response signal to the source node that has transmitted the routing request signal, and receiving a packet from the source node, wherein the transmitting and receiving are performed by the determined destination node. By using the method, traffic in wireless network extreme communications can be distributed at intermediate nodes as well as at destination nodes.
