Abstract
Systems and methods for peer-to-peer communication between user equipment using IP multimedia subsystem (IMS) functionality are provided. Each peer user equipment includes an IMS server and the peer-to-peer communication is established independent of network-based IMS servers. A third user equipment that does not include an IMS server can join the peer-to-peer communication using network-based IMS servers.
Claims10
A method of communication, comprising:
- sending, by a proxy call session control function (PCSCF) module of a first user equipment to a second user equipment, a request for a communication session;
- receiving, by the first user equipment from the second user equipment, an acceptance of the request to establish a communication session;
- and
- establishing a media path for the communication session from the first user equipment to the second user equipment,
- wherein the communication session is setup between the first and second user equipment independent of a network-based PCSCF.
2 more elements
A system, comprising:
- a first user equipment comprising an IP multimedia subsystem (IMS) server;
- and
- a second user equipment comprising an IMS server,
- wherein the IMS servers of the first and second user equipment are configured to establish a communication session independent of network-based IMS servers.
1 more element
A communication device, comprising:
- an IP multimedia subsystem (IMS) server configured to establish a communication session independent of network-based IMS servers, wherein the IMS server comprises
- a proxy call session control function (PCSCF) module;
- a serving session control function (SCSCF) module;
- and
- an application server.
