Description

Voice fallback processing method and device and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for processing a voice fallback.
Background
Currently, a scheme (EPS Fallback ) from 5G to 4G network is defined, a terminal is powered on and resides in 5G, a voice session is established through a 5G core network, and a voice call is registered and initiated in an IMS (IP Multimedia system) network; the 5G wireless network rejects the Voice bearer establishment request, and at the same time, initiates a Packet Service Handover (PSHO) flow from 5G to 4G to switch the call to LTE (Long Term Evolution), and establishes a Voice bearer on EPC (Evolved Packet Core,4G Core network), thereby completing subsequent Voice call connection, and dropping the call from 5G back to Voice LTE (Voice over Long-Term Evolution, long Term Evolution Voice bearer).
When the existing network is deployed, because the EPS Fallback flow simultaneously relates to the IMS flow and the 5G to 4G handover flow, if the IMS flow and the handover flow are in a timing coordination problem, a call will be caused to have a problem:
for example, the network transmits 183 signaling to the calling terminal, and the calling terminal sends an update to confirm the reservation of media resources of the called terminal. When the called party receives the updating message, the called party is still in the 5G network, and no media resource is reserved, so that the resource reservation state of the replied 200OK is zero; however, when the called terminal sends the 200OK, because the terminal has finished the report uploading of the B1 event, the network side sends an indication signaling to the terminal, and releases the 5G DRB (Data Radio Bearer), which results in that the called 200OK cannot be successfully sent. After the called EPS Fallback is completed, the network establishes a special DRB, and the called party sends 180Ring (ringing message) to the network. The network waits for a time when it receives 180Ring, retransmits the update message for which the reply was not received before, and the callee retransmits the 200OK message before because it receives the update message with the same sequence number again. In the scene, the resource reservation state in 200OK replied by the called party aiming at the retransmission updating message is still none; the network understands the reservation of the media resources of the calling party and the called party, and the called party still has no special DRB, so that a downlink RTP (Real-time Transport Protocol) packet is closed, and the call is silent.

if the first update message is received, the first terminal has received a B1 event measurement request or a handover request, and the first terminal falls back to a second wireless communication technology network from a first wireless communication technology network according to the B1 event measurement request or the handover request.
As shown in fig. 2, the second terminal sends a first update message to the first terminal through the calling network and the called IMS network, and when the second terminal receives the first update message and has received the B1 event measurement request or the handover request, the second terminal does not return an update response message for the time being, but feeds back the first update response message to the second terminal through the called IMS network and the calling network after the first terminal falls back to 4G and the resource reservation is completed (which may also be referred to as dedicated bearer establishment completion), where the first update response message is an SDP (Session Description Protocol) message that carries a correct resource reservation state; the subsequent first terminal sends a 180 message, i.e. a ringing message, and rings the first terminal.
As another optional embodiment, before sending the second update message to the second terminal, the method further includes:
