US 2015/0319254 A1 · DEFAULT INITIAL FILTER CRITERIA

Abstract

Methods and apparatus are provided for operating a network element in an Internet Protocol Multimedia Subsystem network including a plurality of application servers. The network element receives a user request associated with a user. The user request is applied to a collection of Initial Filter Criteria associated with the user. If an Initial filter Criteria fires, then normal processing of the user request continues. However, if none of the Initial Filter Criteria fires, then default triggering logic determines the session associated with the user request is not recognised or is unknown. The default triggering logic applies the user request to one or more default iFCs, which include selection criteria defining one or more rules or conditions associated with rejecting or processing the user request (e.g. forwarding to an application server or continuing processing the user request at the network element).

Dependent claims

A method for operating a network element in an Internet Protocol Multimedia Subsystem, IMS, network including a plurality of application servers and a collection of Initial Filter Criteria, iFC, the method comprising:

receiving a user request associated with a user;
applying a collection of Initial Filter Criteria, iFC, associated with the user to the user request;
determining whether the session associated with the user request is recognised;
applying one or more default iFCs to the user request when the session associated with the user request is not recognised, wherein the default iFCs comprise selection criteria defining one or more rules associated with rejecting or processing the user request.

1 more element

A network element for use in an Internet Protocol Multimedia Subsystem, IMS, network including a plurality of application servers, the network element comprising:

a receiver, a transmitter, memory, and processing logic, the processing logic being connected to the receiver, the transmitter and the memory, wherein:
the receiver is configured to receive a user request associated with a user;
and
the processing logic comprises:
trigger logic configured to apply a collection of Initial Filter Criteria, iFC, to the user request;
default trigger logic configured to:
determine whether the session associated with the user request is recognised;
and
apply one or more default iFCs to the user request when the session associated with the user request is not recognised, wherein the default iFCs comprise selection criteria defining one or more rules associated with rejecting or processing of the user request.
