Suppressing Third Party Registration and Third Party Deregistration Actions

摘要

An S-CSCF component within an IMS receives a registration request associated with the UE. The registration request is associated with the UE switching from a first network that provides support for a first feature set to a second network that provides support for the second feature set. Instead of performing registration actions and deregistration actions with an application server in response to the registration request, the S-CSCF compares the feature tags of the registration request with previous feature tags that are associated with currently registered features. The S-CSCF causes a registration action to be performed in response to determining that the current registration request includes a feature tag that is not currently registered. The S-CSCF causes a deregistration action to be performed in response to determining that the current registration request does not include a feature that is currently registered.

1. A method, comprising:
receiving, at a computing device associated with an IP multimedia subsystem (IMS), a registration request associated with a user equipment (UE), the registration request including a feature tag that specifies a requested feature to register with an application server in the IMS; accessing registration data, the registration data indicating a currently registered feature with the application server; comparing the currently registered feature with the requested feature; and performing a registration action involving the application server based, at least in part, on the comparison.
