Methods, systems, and computer readable media for performing single radio voice call continuity (SRVCC) handovers
First Claim
1. A method for performing a single radio voice call continuity SRVCC) handover, the method comprising:
- at a testing platform;
receiving, via a communications channel for ex hanging messages between a first session initiation protocol (SIP) peer and a second SIP peer, a first message for triggering a bearer deletion procedure associated with a call between the first SIP peer and the second SIP peer; and
in response to receiving the first message or a related message, triggering the bearer deletion procedure prior to changing an access technology,wherein a serving gateway is emulated by the testing platform, wherein the first message is sent from the first SIP peer to the second SIP peer, wherein a delete bearer request message is sent from the second SIP peer to the serving gateway in response to receiving the first message, and wherein the serving gateway triggers the bearer deletion procedure in response to receiving the delete bearer request message, andwherein the first and second SIP peers use the communication channel to synchronize when the first and second SIP peers stop packet transmission and reception along a bearer path for the call in order to perform changing of the access technology without losing packets.

Abstract
Methods, systems, and computer readable media for performing single radio voice call continuity (SRVCC) handover are disclosed. According to one method, the method occurs at a testing platform. The method includes receiving, via a communications channel for exchanging messages between a first session initiation protocol (SIP) peer and a second SIP peer, a first message for triggering a bearer deletion procedure associated with a call between the first SIP peer and the second SIP peer. The method also includes in response to receiving the first message or a related message, triggering the bearer deletion procedure prior to changing an access technology.

11. A system for performing a single radio voice call continuity (SRVCC) handover, the system comprising:
a testing platform comprising; a communications interface associated with a communications channel for exchanging messages between a first session initiation protocol (SIP) peer and a second SIP peer, the communications interface configured to receive a first message for triggering a bearer deletion procedure associated with a call between the first SIP peer and the second SIP peer; and a serving gateway emulated using at least one processor, wherein the serving gateway is configured to, in response to receiving the first message or a related message, trigger the bearer deletion procedure prior to changing an access technology, wherein the first message is sent from the first SIP peer to the second SIP peer, wherein a delete bearer request message is sent from the second SIP peer to the serving gateway in response to receiving the first message, and wherein the serving gateway initiates the bearer deletion procedure in response to receiving the delete bearer request message, and wherein the first and second SIP peers use the communication channel to synchronize when the first and second SIP peers stop packet transmission and reception along a bearer path for the call in order to perform changing of the access technology without losing packets. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A non-transitory computer readable medium comprising computer executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:
-
at a testing platform; receiving, via a communications channel for exchanging messages between a first SIP peer and a second session initiation protocol (SIP) peer, a first message for triggering a bearer deletion procedure associated with a call between the first SIP peer and the second SIP peer; and in response to receiving the first message or a related message, triggering the bearer deletion procedure prior to changing an access technology, wherein a serving gateway is emulated by the testing platform, wherein the first message is sent from the first SIP peer to the second SIP peer, wherein a delete bearer request message is sent from the second SIP peer to the serving gateway in response to receiving the first message, and wherein the serving gateway triggers the bearer deletion procedure in response to receiving the delete bearer request message, and wherein the first and second SIP peers use the communication channel to synchronize when the first and second SIP peers stop packet transmission and reception along a bearer path for the call in order to perform changing of the access technology without losing packets.
