Method and node in a telecommunications network

摘要

During a registration procedure by a User Equipment (UE) via a Proxy Call Session Control Function (P-CSCF) node and a Serving Call Session Control Function (S-CSCF) node, the S-CSCF node provides a policy indicator in a response message to a register request message. The policy indicator enables subsequent operation of the node to be controlled according to whether or not a registered UE has an associated policy. As such, delays (such as delays associated with retrieving an associated policy) are only experienced by UEs that have previously been determined as having such an associated policy, rather than all UEs being affected in the same way.

1. A method in a Proxy Call Session Control Function (P-CSCF) node of a telecommunications network, the method comprising:
receiving from a Serving Call Session Control Function (S-CSCF) node of the telecommunications network a response to a register request message, the response containing a policy indicator relating to a user equipment making a register request, wherein the policy indicator provides an indication as to whether the user equipment has an authorization policy associated therewith; determining from the policy indicator whether the user equipment has an associated authorization policy; determining whether to delay sending a registration acceptance message to the user equipment depending on whether the user equipment has an associated authorization policy; and controlling a further operation of the P-CSCF node depending upon whether or not the user equipment is determined as having an associated authorization policy, wherein controlling the further operation of the P-CSCF node comprises:
if it is determined that the user equipment has an associated authorization policy, fetching the associated authorization policy for a location identified by the response; andif the user equipment has an associated authorization policy, delaying sending the registration acceptance message to the user equipment.
