Abstract
Apparatuses, methods, and systems are disclosed for selecting a transport layer protocol for SIP messaging. One apparatus includes a processor and a transceiver that receives a SIP message from a remote unit, the SIP message comprising a first request to initiate a session for an IMS MMTEL. The processor determines that the SIP message is communicated using TCP as a transport layer protocol and forwards the first request to a network entity, wherein the first request is sent using UDP as the transport layer protocol.
Claims23
An apparatus comprising:
- a transceiver that receives a session initiation protocol (“SIP”) message from a remote unit, the SIP message comprising a first request to initiate a session for an Internet Protocol Multimedia Subsystem (“IMS”) Multimedia Telephony Communication Service (“MMTEL”);
- and
- a processor that:
- determines that the SIP message is communicated using transmission control protocol (“TCP”) as a transport layer protocol;
- and
- forwards the first request to a network entity, wherein the first request is sent using user datagram protocol (“UDP”) as the transport layer protocol.
