摘要： A first communication provider supports an IP multimedia subsystem (IMS) having a border session control function (BGCF) that receives SIP requests. The SIP requests correspond to different SIP methods and specify various feature tags. The feature tags correspond to available services or media types that may be available from the IMS of a second communication provider. When receiving a SIP request that addresses a user supported by the second communication provider, the BGCF of the first communication provider checks the method and feature tag of the SIP request to make sure that they are supported by IMS of the second communication provider. If they are not, the SIP is rejected and failure message is returned. The BGCF may also modify certain parameters of the SIP request, such as by removing one or more offered codecs or preconditions.

摘要： Solutions for providing a data traffic session with proxy-call session control function (P-CSCF) restoration include: receiving an indication, by an application server (AS), that a user equipment (UE) registered with a first proxy node; receiving, by the AS, from a call session control function, a first indication that the first proxy node is unavailable; based on at least receiving the first indication that the first proxy node is unavailable, transmitting, by the AS, to a subscriber information node, a first message triggering proxy node restoration (e.g., over an N71 interface); receiving an indication, by the AS, that the UE is registered with a second proxy node different than the first proxy node; and based on at least receiving a session initiation message, establishing the data traffic session for the UE with the second proxy node.

摘要： Telecommunications network components configured to manage call control of a communication session of user equipment are described herein. An anchoring network device may proxy signaling traffic for the communication session. The anchoring network device may determine a routing identifier based at least in part on which access network, or which type of access network, is carrying the communication session, and may transmit state information of the communication session to a call-control server in association with the routing identifier. The call-control server may provide control information of the communication session to the anchoring network device in response to the state information. The anchoring network device may modify the communication session, e.g., by adding or dropping one or more parties, in response to the control information. The routing identifier may be determined based at least in part on capabilities of a communication session indicated in a session-initiation message.

摘要： Solutions for providing a data traffic session with proxy-call session control function (P-CSCF) restoration include: receiving an indication, by an application server (AS), that a user equipment (UE) is registered with a first proxy node (e.g., a P-CSCF); subscribing, by the AS, with a status repository, to a status of the first proxy node; receiving, by the AS, from the status repository, an indication that the first proxy node is unavailable; based on at least receiving the indication that the first proxy node is unavailable, transmitting, by the AS, to a subscriber information node, a first message triggering proxy node restoration; receiving an indication, by the AS, that the UE is registered with a second proxy node different than the first proxy node; and based on at least receiving a session initiation message, establishing the data traffic session for the UE with the second proxy node.

摘要： A solution for an enhanced telephony application server session management. A TAS may fork an incoming invite for packet switched connectivity to all user devices of a same user account registered for parallel forking. When receiving a SIP client failure response from one of the user device, TAS will determine whether a SIP 18X provisional response is received prior to the client failure response from the same user device. If such a provisional response is not received prior to the client failure response, TAS will not terminate the invite forking.
