Optimizing call bearer path using session initiation protocol proxy

摘要

A system that incorporates the subject disclosure may include, for example, a serving device receiving a first message from a gateway device coupled to a communication network, the first message comprising a first session descriptor protocol relating to a port of the network connecting to equipment of a first subscriber of the network to originate a call to a mobile communication device of a second subscriber of the network, whereby the serving device and the gateway device comprise nodes on a signaling path for the call. The serving device sends a second message to the gateway device, the second message comprising a second session descriptor protocol relating to the serving device, for delivery to the network to facilitate a bearer path between the network and the serving device, wherein the gateway device is not a node of the bearer path. Other embodiments are disclosed.

主权项

1. A call session control function server comprising:
a memory to store instructions; and a controller coupled to the memory, wherein responsive to executing the instructions, the controller performs operations comprising: receiving a first message via a communication network from originating equipment of a first subscriber of the communication network, the first message regarding origination of a call from the first subscriber to a mobile communication device of a second subscriber of the communication network; sending a second message to a gateway mobile switching center communicatively coupled with the communication network, wherein the gateway mobile switching center comprises a session initiation protocol proxy server, and wherein the second message comprising a first session descriptor protocol relating to a port of the communication network connecting to the originating equipment, whereby the gateway mobile switching center comprises a node on a signaling path for the call; receiving a third message directly from the gateway mobile switching center, the third message comprising a second session descriptor protocol relating to a serving mobile switching center communicatively coupled with the mobile communication device, to facilitate a bearer path between the communication network and the serving mobile switching center, wherein the gateway mobile switching center is not utilized in the bearer path as a result of the communication network receiving the second session descriptor protocol of the serving mobile switching center instead of receiving a third session descriptor protocol of the gateway mobile switching center.
