It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The call bearer establishment method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

At present, the coverage rate of the VoNR network is low, the VoNR call technology is immature, the LTE network coverage is wide, and the VoLTE technology is mature, so that the VoNR switching VoLTE scenes in the current call in the network are many.

Before the VoNR call is answered, the network provides a bearer mapping relation from NR to LTE, and after the terminal equipment moves from NR to an LTE area, the network can initiate NR to LTE switching, so that the VoNR bearer is mapped to the VoLTE bearer, and the terminal equipment can make a call under VoLTE. However, as the VoNR technology is not mature, the compatibility between the network and the terminal is poor, and the like, there are many problems in the bearer mapping before answering (for example, the bearer mapping between NR and LTE cannot be detected by the terminal device), and after the terminal NR is switched to LTE, the terminal detects that the bearer is not matched, and the terminal Modem reports the bearer exception to the network and interrupts the current call. The reason that the terminal Modem finishes the current call is that the terminal Modem detects that the network does not distribute 4G load to the terminal equipment within the specified time, so that the terminal equipment does not have a proper load channel to send service data such as voice and video, and the terminal equipment interrupts the current call, and thus, the call quality of the terminal equipment is poor.

In the embodiment of the application, when the terminal device is switched from the first network to the second network to execute a call process, if the call bearer of the second network is abnormal, the terminal device may send a first request to the network side device to request the network side device to reallocate the call bearer of the second network, and receive the call bearer information sent by the network side device, so that the terminal device may reestablish a call connection according to the call bearer information to perform a call in the second network. In the scheme, the terminal device can send the first request to the network side device when the terminal device is switched from the first network to the second network to execute the call process and the call bearer of the second network is abnormal, so that the network side device is requested to reallocate the bearer resources, the probability that the terminal device acquires the bearer resources is improved, the success rate of switching the VoNR to the VoLTE call is improved, and the call quality of the terminal device is improved.

S203, the terminal equipment establishes a VoNR conversation.

S204, the terminal equipment moves from the VoNR area to the non-VoNR area, and the network instructs the terminal equipment to carry out switching from VoNR to VoLTE.

Specifically, the network may instruct the terminal device to perform the VoNR to VoLTE handover through an air interface signaling.

S205, the terminal equipment carries out mapping from VoNR bearing to VoLTE bearing.

S206, when the terminal device detects that the mapping of the VoLTE bearer is abnormal, the terminal device initiates a PDNrequest carrying a Handover type and a voice parameter, and informs the network to reestablish the VoLTE voice bearer.

It can be understood that, due to the problems of mapping parameter configuration error, network and terminal compatibility, etc., the terminal 5G bearer is mapped to the 4G bearer exception, and after the terminal device falls back to 4G, the 4G bearer exception is detected.
