    • 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.

    • Methods and apparatuses for updating policy and charging rules relating to early dialogs in session initiation protocol forking in a telecommunications network. A node comprises a receiver (304), configured to receive a plurality of preliminary responses originating from a plurality of terminating end points as part of Session Initiation Protocol, SIP, forking. The node comprises an early dialog controller (314), configured, for each received preliminary response, to determine a unique identifier and to control a transmitting means, which may be a transmitter (302), to transmit a corresponding preliminary message comprising the unique identifier to a further node (400) for use as a Policy and Charging Rules Function, PCRF (200), for creating an early dialog by the further node. The receiver is further configured to receive updated data for at least one of the preliminary responses. The node further comprises an updated dialog controller (316) configured to retrieve the unique identifier corresponding to the at least one preliminary response and control the transmitter to transmit an updating message based on the updated data and comprising the retrieved unique identifier to the further node for updating the corresponding early dialog.

    • The present invention faces the issue of UE enabled to communicate with an IP Multimedia Subsystem following protocol versions older than Release 9, and provides for an alternative P-CSCF restoration procedure. In this alternative P-CSCF restoration procedure, the UE submits to the IMS network UE capability information indicating that the UE is enabled to receive a list with one or more further available P-CSCF entities and to re-register in the IMS network with one of them; at least one entity of the IMS network stores this UE capability information; upon detecting unavailability of the P-CSCF entity to handle a terminating request towards the UE, the UE capability information is provided towards and access network entity; the access network entity determines based on the received UE capability information that the UE is enabled to receive a list with one or more further available P-CSCF entities, obtains the list with further available P-CSCF entities and submits said list to the UE; and the UE reregisters to a further P-CSCF entity selected from the list.
    • 本发明面向能够在比版本9更早的协议版本之后与IP多媒体子系统进行通信的UE的问题,并提供替代的P-CSCF恢复过程。 在该替代的P-CSCF恢复过程中,UE向IMS网络UE提交表明UE能够使用一个或多个其他可用P-CSCF实体接收列表的能力信息,并且在IMS网络中重新注册一个 的; IMS网络的至少一个实体存储该UE能力信息; 在检测到P-CSCF实体处理向UE的终止请求的不可用性时,向接入网实体提供UE能力信息; 所述接入网络实体基于所接收的UE能力信息来确定所述UE是否能够使用一个或多个另外可用的P-CSCF实体接收列表,使用其他可用P-CSCF实体获得所述列表并将所述列表提交给所述UE; 并且UE重新注册到从列表中选择的另外的P-CSCF实体。
