Abstract

See full text

Methods and apparatuses, including computer program products, are described for synchronization of shared initial filter criteria in an IP Multimedia Subsystem (IMS) network. A first computing device in the IMS network transmits a registration request to a second computing device in the IMS network. The first computing device receives a response to the registration request from the second computing device, including an identifier associated with a shared initial filter criteria set stored at the first computing device. The first computing device determines whether the shared initial filter criteria set corresponding to the identifier is stored at the first computing device and transmits a retrieval request to the second computing device if the shared initial filter criteria set corresponding to the identifier is not stored. The first computing device receives the shared initial filter criteria set from the second computing device, and stores the shared initial filter criteria set.
