Problems solved by technology

[0005] However, since the IMS system sends the cancel call service request to the VOLTE terminal as a SIP message through the I / S-CSCF and P-CSCF on the user plane channel, the S-GW only transparently transmits or buffers the call cancel service request, and The MME continues to page the VOLTE terminal. After the VOLTE terminal establishes a connection with the S-GW, the S-GW sends the buffered service request to the VOLTE terminal, which causes the VOLTE terminal to receive repeated service requests in the IMS domain and the CS domain, and then lead to poor user experience

Abstract

Embodiments of the present application provide a service processing method, device, and system. The method includes: after the serving gateway S-GW caches the Internet Protocol Multimedia Subsystem IMS service request message corresponding to the voice VOLTE terminal corresponding to the long-term evolution, send the request message from the signaling plane channel Receive the IMS service cancellation request message corresponding to the VOLTE terminal sent by the packet data gateway P-GW; the S-GW determines the IMS service request message corresponding to the IMS service cancellation request message in the cache, and discards the IMS service request message. It is used to prevent the VOLTE terminal from receiving repeated service request messages in the IMS domain and the CS domain.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular, to a service processing method, device, and system. Background technique [0002] With the continuous development of communication technology, Voice Over LTE (VOLTE) terminals based on Long Term Evolution (LTE) are more and more widely used. VOLTE terminals can be ) domain or circuit switched (Circuit Switched, CS) domain to acquire call and short message services. [0003] Since better services can be provided to VOLTE terminals through the IMS domain, when the VOLTE terminal is the requested terminal (called terminal or short message receiving terminal) and the VOLTE terminal accesses the IMS domain, the IMS system usually sends the VOLTE terminal to the VOLTE terminal through the IMS domain first. VOLTE sends the request. When the request cannot be sent to the VOLTE terminal through the IMS domain, the request is sent to the VOLTE terminal...
