Mobility management entity for high data rate wireless communication networks
ActiveUS7457265B2Reduce amountEasy to manageTime-division multiplexData switching by path configurationSession controlGranularity
A session controller provides mobility management support in a 1xEVDO wireless communication network, such as one configured in accordance with the TIA / EIA / IS-856 standard. Operating as a logical network entity, the SC maintains location (e.g., a pointing tag) and session information at an access network controller (ANC) granularity, thus allowing it to track access terminal (AT) transfer between ANCs but within subnet boundaries, where a network subnet comprises one or more ANCs. This allows a packet control function (PCF) to maintain location information at a packet zone granularity, thereby reducing mobility management overhead at the PCF. The SC provides updated tag and session information to PCFs, ANCs, and other SCs as needed. Information exchange with other SCs arises, for example, when two or more SCs cooperate to maintain or transfer routing and session information across subnets.

Dynamic facsimile transcoding in a unified messaging platform
Facsimile transcoding is dynamically invoked for devices that do not support T.38 fax protocol. In this way, a unified messaging platform can process facsimiles from endpoints that are not T.38 capable without using without digital signal processor resources. Dynamic fax transcoding can be performed at a session border controller, allowing transcoding resources to be engaged only for non-T.38 endpoints rather than for all calls on an interface.

Method and apparatus for network-based admission control using path-coupled quality of service signaling
ActiveUS20070008882A1Improved admission controlImproved of medium path routingError preventionTransmission systemsAccess networkNetwork control
A Resource ReSerVation Protocol (RSVP) proxy is used in combination with a signaling proxy to provide improved admission control, Quality of Service (QoS) reservation, and media path routing. This avoids entangling call signaling with media plane functions as required with Session Border Controllers (SBCs). A QoS access network control scheme, such as Packet Cable Multi-Media (PCMM) and / or Dynamic Quality of Service (DQoS), is conventionally used to set up QoS and other flow states on an access network. However, the gate parameters established during this access operation are also provided to an RSVP proxy in an edge router. The gate parameters trigger the RSVP proxy to attempt to establish a QoS reservation over the packet network toward a media flow destination. If admission control for the QoS reservation is successful, the edge router permits the signaling proxy to complete the media call.

Method of Providing Session Mobility
ActiveUS20070189220A1Improved session mobilityKeep it privateMultiplex communicationConnection managementSession Initiation ProtocolTelecommunications network
The invention concerns a method of providing session mobility to an IP based real-time session in a telecommunications network whereby the telecommunications network uses the session initiation protocol for the setup and control of the session. The session comprises a media stream between a first terminal associated to a first network access point of the telecommunications network and a second terminal associated to a second network access point of the telecommunications network. A re-invite session initiation protocol signalling message related to session mobility of said session is intercepted at a session-related session border controller of the telecommunications network. Said session border controller initiates a corresponding session hand-over of said session. In said session hand-over, the media stream of said session is redirected to a new network access point of the first terminal and / or a new terminal.

Systems and methods for interworking QSIG and H.323 signaling in a SIP-based network
A SIP-based network architecture is defined allowing a variety of access methods for interfacing QSIG-based signaling devices. The QSIG-based signaling devices are typically enterprise-based PBXs that either interface directly via QSIG, or adapt QSIG signaling to related signaling protocols via gateways, which can be customer premise or network based. The gateways can either interwork QSIG signaling or tunnel QSIG signaling over H.323, SIP, or other protocols. Upon reaching the SIP-based network, Session Border Controllers process the signaling. The Session Border Controllers terminate the tunnel (if used) and extracts the QSIG signaling for interworking to SIP, thereby facilitating a homogeneous SIP-based core network. In addition to interworking QSIG signaling, the Session Border Controllers perform other signaling related functions for the SIP-based network that are performed at a point as near as possible to the network's edge.

A cable modem integrated session border control circuit operates as a point of demarcation between a local area network (LAN) and a DOCSIS network and, in response to receiving a Session Initiation Protocol (SIP) message, which includes Session Description Protocol (SDP), from a VoIP device coupled to the LAN, communicates with a Cable Modem Termination System (CMTS) to take advantage of DOCSIS Dynamic Quality of Service (DQoS) if a VoIP session between the VoIP device and a remote endpoint includes use of the DOCSIS network. The cable modem integrated session border controller further determines required service flow attributes. If required service flow attributes, as determined from the SDP of the SIP message, matches service flow attributes of an existing UGS service flow with a CMTS, a DOCSIS Dynamic Service Chance (DSC) request is used to add an additional sub flow to the existing UGS service flow. If attributes fail to match attributes of all existing UGS service flows, a DOCSIS Dynamic Service Change (DSC) request is used to initiate an additional UGS service flow with the required service flow attributes.
