Abstract:
1. A Session Capability Interaction Manager (SCIM) having a processor and a memory, the SCIM for performing a method to allow devices to operate across IP Multimedia Subsystem (IMS) networks, comprising: operating the SCIM in an IMS network, wherein the IMS network includes a Session Initiation Protocol (SIP) application server, and wherein the SIP application server includes the SCIM that interacts with a Serving Call Session Control Function (S-CSCF) and a Proxy Call Session Control Function (P-CSCF); at the SCIM, recognizing an identifier of a remote device when the remote device enters the IMS network, wherein the remote device enters the IMS network from a remote IMS network and, wherein the remote device operates a remote set of features provided by the remote IMS network, when in the remote IMS network; at the SCIM, utilizing a Common Open Policy Service (COPS) protocol to contact a remote SCIM in the remote IMS network using the identifier, wherein the SCIM communicates a request to the remote SCIM in the remote network for whether the first device is allowed to access the remote set of features, wherein, upon receiving the identifier, the remote SCIM gathers and conveys information about the remote device, the information including data about the remote set of features; receiving at the SCIM the information from the remote SCIM, wherein the information includes a decision on whether the remote device is allowed to operate the remote set of features; determining whether to allow the remote device to operate in the IMS network based on, in part, the information; and when the remote device is allowed to operate the remote set of features, then establishing a path between the P-CSCF in the IMS network and an application server in the remote IMS network, by which the remote device accesses the remote set of features.
