Problems solved by technology
[0006] In the process of realizing the above-mentioned present invention, the inventor found that at least the following problems exist in the prior art: in the existing technical solution for terminal switching, in the process of terminal switching, if the terminal that sends the switching request, that is, the terminal before the switching The terminal used by the user is receiving the message sent by the message sending terminal, so according to the existing technology, the terminal must terminate the session with the message sending terminal before switching, and cannot continue to correctly receive the message sent by the message sending terminal, that is, terminal switching Previously received messages will be lost
On the other hand, according to the existing technology, the terminal used by the user after the terminal switch only establishes a session with the message sending terminal, which is analogous to the session between the terminal before the switch and the message sending terminal, and does not additionally process unfinished sessions before the switch. Transaction, that is, after the user switches, the terminal cannot receive the messages that the terminal failed to receive correctly before the switching

The present invention relates to mobile communication technologies, and discloses a method and a device for handover between User Equipment (UE) in a process of sending a message to enable the after-handover UE receive messages accurately. The method includes: receiving a UE handover request sent by a before-handover UE, wherein the UE handover request carries an identifier of an after-handover UE and indication parameters for sending a message; and sending the message to the after-handover UE according to the identifier of the after-handover UE and the indication parameters for sending the message. The embodiments of the present invention are applied to handover between UEs in the process of sending a message.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for switching terminals during message sending. Background technique [0002] 3GPP / 3GPP2 is an international standard organization that formulates the third generation mobile communication system. Among these international standards, one of them is IP Multimedia Subsystem. IMS is a communication system based on the SIP (session initiation protocol, session initiation protocol), which provides a set of standard architecture for multimedia services, and can quickly provide and deploy various multimedia services. [0003] The Internet Engineering Task Force (IETF) is responsible for the development and formulation of Internet-related technical specifications. Its MMUSIC working group is committed to the standardization of multimedia session control protocols. Sending messages in message sessions or multimedia sessions is one of the applicati...
