Flow mobility filter rule verification

摘要

A method and system for flow mobility filter rule verification is provided. According to an embodiment of the present invention, a network node of a telecommunications packet network is configured to receive filter rules provided by a user entity (UE) relating to a requested IP-CAN session. The filter rules are applied by a Policy and Charging Control (PCC) network architecture for the session. The network node is also configured to compare received filter rules with Inter-Mobility Policies (IMPs) of the user in order to determine if the filter rules match with the user's IMPs, and to send a filter rule verification response indicating whether or not the filter rules match the user's IMPs.

1. A telecommunications system of a telecommunications packet network comprising:
at least one processor; at least one non-transitory computer readable storage medium comprising instructions, wherein execution of the instructions by the at least one processor causes the telecommunication system to: receive filter rules provided by a user entity (UE) relating to a requested Internet Protocol Connectivity Access Network (IP-CAN) session, wherein the filter rules are applied by a Policy and Charging Control (PCC) network architecture for the IP-CAN session, wherein the IP-CAN session is initiated by the UE conveying bootstrap information to an Access Network Discovery and Selection Function (ANDSF), which responsively identifies a set of Inter Mobility Policies (IMPs) corresponding to the UE to be applied to the IP-CAN session; retrieve the IMPs associated with the UE from a database in the telecommunications packet network, wherein the IMPs are a set of instructions to the UE for accessing the telecommunications packet network for one or more applications; convey a filter rule verification request for the received filter rules to the ANDSF; compare, at the ANDSF, the received filter rules with the retrieved IMPs associated with the UE so as to determine if the filter rules match with the IMPs associated with the UE; and send, from the ANDSF, a filter rule verification response indicating whether or not the filter rules match the IMPs associated with the UE, wherein the filter rules are applied to the IP-CAN session when the filter rule verification response indicates that the filter rules match.
