Method, apparatus and computer program product for source identification for single radio voice call continuity

摘要

An apparatus for enabling source identification for single radio voice call continuity (SR-VCC) in relation to a handover between different RATs may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to perform at least receiving an indication of handover between a first radio access technology and a second radio access technology, defining an identity value for source identification associated with the first radio access technology by utilizing a source identification format associated with a third radio access technology, and providing the defined identity value to a network device associated with a target of the handover. A corresponding method and computer program product are also provided.

主权项

1. A method comprising:
receiving an indication of handover between a first radio access technology and a second radio access technology; defining, at a mobile switching center (MSC) or mobile management element (MME), an identity value for source identification in a handover request associated with the first radio access technology by utilizing a source identification format associated with a third radio access technology, wherein defining the identity value for source identification comprises utilizing a Serving Area Identity (SAI) format, and wherein defining the identity value comprises:
defining one or more alternative identification values corresponding to one or more parameters; andreplacing the one or more parameters with the one or more alternative identification values; and providing the defined identity value to a network device associated with a target of the handover.
