摘要： The present invention relates to a method for enabling IP multimedia system, IMS, signalling traffic in a Policy and Charging Control, PCC, environment between a user equipment (21), UE, and a proxy call session control function (16), P-CSCF, device. The method comprises the following steps: 1. The UE (21) requests (10) in a gateway (17), GW, at least one P-CSCF device address for IMS signalling traffic between the UE (21) and the P-CSCF device (16). 2. The GW (17) sends (11) a request for a policy decision for the IMS signalling traffic to a first policy control node (22,23), PCN. 3. The first PCN (22,23) responds (12) to the GW (17) with policy information defining the policy decision for the IMS signalling traffic, 4. The GW (17) installs (13) the policy information and provides the P-CSCF device address/-es assigned to said information to the UE (21). What particularly characterizes the method is a step where the first PCN (22, 23) defines (14) the policy information for the IMS signalling traffic. It is defined in the form of at least one instruction, wherein the first PCN (22, 23) responds with the defined instruction/-s and with P-CSCF device address/-es assigned to said instruction/-s to the GW (17).

摘要： The present invention relates to a packet data communication system comprising first (10) and second (20) packet data nodes communicating over a packet data communication protocol. Each first and second node comprises a number of processing arrangements (11 1 , 11 2 , 11 3 ; 21 1 , 21 2 , 21 3 , 21 4 ) handling a number of communication contexts, wherein the communication contexts handled in a processing arrangement of a first node are/can be handled in different processing arrangements in one or more second packet data nodes. When, in a first packet data node (10), a processing arrangement is malfunctioning (11 2 ) or when it has deleted all, or a plurality of the communication contexts handled by it, a message containing the (IP) end point address of said processing arrangement is sent by said first packet data node (10) to at least one second packet data node (20), and if said second packet data node(s) (20) comprise(s) end-point mapping information about and can identify which of its processing arrangements (21 1 , 21 2 , 21 3 , 21 4 ) are handling communication contexts with the indicated first packet data node end point address, said end-point mapping information is used to delete such communication contexts in the respective processing arrangements (21 1 , 21 4 ) in said second packet data node(s) (20), otherwise the first packet data node (10) is, directly or indirectly, informed such that said first node (10) may use a conventional/default procedure to enable removal of said communication contexts in said second packet data node(s) (20).

摘要： A method is provided for facilitating recovery from the failure of a P-CSCF (13) within an IP multimedia Subsystem network. A gateway (11), such as a GGSN, monitors signals arriving at the gateway from the P-CSCF and provides an indication if the monitored signals become unacceptable, for example because of an interruption in the signals. The gateway (11) responds by signalling the unavailability of the P-CSCF (13) to user equipment (10), which was associated with the P-CSCF during a previous registration with the IMS network. In response, for example, the user equipment affected by the failure may request re-registration with the IMS network using a different available P-CSCF.
摘要翻译：提供了一种用于促进从IP多媒体子系统网络内的P-CSCF（13）的故障恢复的方法。诸如GGSN的网关（11）监视从P-CSCF到达网关的信号，并且例如由于信号中断而提供监视信号是否不可接受的指示。网关（11）通过在先前向IMS网络注册期间向与P-CSCF相关联的用户设备（10）发信号通知P-CSCF（13）的不可用性。作为响应，例如，受故障影响的用户设备可以请求使用不同的可用P-CSCF与IMS网络重新注册。
