Embodiment 1

[0032] This embodiment provides a voice call method performed on the base station side. figure 1 It is a flow chart of the voice call method at the base station side according to the first embodiment of the present invention.

[0033] Step S101, by interacting with other base stations, the voice service support information of other base stations is obtained.

[0034] In this embodiment, types of base stations include, but are not limited to: gNB base stations, eNB base stations (4G base stations), 3G base stations, and 2G base stations. Preferably, the base station is a gNB base station, and an eNB base station is secondly selected.

[0035] In this embodiment, the voice service support information includes: whether each base station cell corresponding to the base station supports the voice service, and the voice frequency point corresponding to the base station cell supporting the voice service.

[0036] Specifically, signaling interaction with other base stations may be pe...

Embodiment 1

[0044] With respect to Embodiment 1, this embodiment correspondingly provides a voice calling method performed on a terminal side. figure 2 It is a flow chart of the voice call method at the terminal side according to the second embodiment of the present invention.

[0045] Step S201, receiving a broadcast message sent by a base station, the broadcast message carrying voice service support information of the base station and voice service support information of other base stations.

[0046] Specifically, after receiving the broadcast message sent by the base station, the terminal may analyze the broadcast message to obtain the voice service support information of the base station and the voice service support information of other base stations carried in the broadcast message.

[0047] Step S202, when initiating a voice call, according to the voice service support information of the base station carried in the broadcast message and the voice service support information of oth...

Embodiment 3

[0054] This embodiment provides another voice call method performed on the base station side. Such as image 3 Shown is a flow chart of a voice call method at the base station side according to the third embodiment of the present invention.

[0055] In step S301, when a terminal accesses a cell of a base station, a voice call initiated by the terminal is received.

[0056] In this embodiment, the voice call is used to establish a voice service connection.

[0057] A terminal in an idle state or a connected state can initiate a voice call to the base station cell by sending an RRC Setup Request (Radio Resource Control Setup Request, radio resource control setup request) message carrying a voice call indication to the base station cell.

[0058] When a terminal initiates a voice call, it selects a base station cell to access. In this embodiment, the base station cell that the terminal selects to access is a cell that does not support voice services.

[0059] Step S302, if the...

Abstract

The invention discloses a voice calling method and device and a storage medium. The method comprises the following steps: acquiring voice service support information of other base stations by interacting with the other base stations; sending a broadcast message carrying the voice service support information of the base station and the voice service support information of other base stations to theterminal; when the terminal initiates a voice call, accessing a base station cell supporting the voice service and having a voice frequency point in a voice frequency band of the terminal according to the broadcast message, and establishing a voice service connection; or, when the terminal accesses the base station cell, receiving a voice call initiated by the terminal; if the base station cell does not support the voice service, acquiring voice frequency band information of the terminal; according to the voice frequency band information of the terminal, controlling the terminal to migrate the voice service to an adjacent cell of which the voice frequency point is located in the voice frequency band of the terminal, so the terminal and the adjacent cell establish voice service connection.The call completing rate can be improved, the call completing time delay is reduced, and the user experience effect is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a voice calling method, device and storage medium. Background technique [0002] With the continuous progress of communication technology, the mobile communication network has developed to 5G (5th-Generation, fifth-generation mobile communication technology). In the 5G era, voice services are still one of the important services. The EPS (Evolved Packet System, Evolved Packet System) fallback (fallback) scheme allows 5G terminals to reside on 5G NR (New Radio, new air interface), but does not provide voice services on 5G NR; when the terminal initiates a voice call, the network passes The directional process switches the terminal to LTE (Long Term Evolution, long-term evolution), and provides voice services through VoLTE (Voice over Long-Term Evolution, long-term evolution voice bearer). [0003] Although the EPS fallback scheme can enable the terminal to finally ob...
