For ease of understanding, the description of the concepts related to the embodiments of the application is given in part by way of example for reference.

1. New air interface carrying voice (Voice over New Radio, voNR)

The 5G Radio access part is called NR (New Radio), and the 5G-based voice service is called VoNR. Namely, the NR user can directly carry out voice service based on the NR network without falling back to the LTE network, so that higher-quality voice service experience and higher-rate data service experience are obtained. That is, voNR is a voice solution for 5G networks.

2. Independent networking (Standalone, SA)

The SA is a 5G networking mode, i.e. a core network is equipped with a base station. The method is equivalent to using a 5G technology from a core network to a base station, and has low delay and better user experience.

At present, voice services are still one of the main services of operators. As the 5G base station starts to be used, voice service of the 5G network usually adopts a VoNR manner. In the process of implementing a voice call between two terminal devices, communication between the terminal device and a base station needs to be established first. The following description will be given by way of fig. 1.

Fig. 1 is a schematic flow chart of establishing communication connection between a calling terminal and a base station, as shown in fig. 1, including:

step 1, a calling terminal sends an INVITE message to a base station.

And 2, the base station responds to the INVITE sent by the calling terminal and sends 100try information to the calling terminal.

Step 3, the base station sends a protocol data unit (Protocol Data Unit, PDU) session modification command (session modification command) to the calling terminal.

And 4, the calling terminal sends a PDU session modification completion (session modification complete) message to the base station.

And step 5, the base station sends a radio resource control (Radio Resource Control, RRC) Reconfiguration message to the calling terminal.

And 6, the calling terminal sends an RRC reconfiguration complete (Reconfiguration Complete) message to the base station.

And 7, the calling terminal reports the neighbor cell measurement report to the base station.

And 8, the base station transmits a SESSION PROGRESS (session_progress) message to the calling terminal.

And 9, the calling terminal sends a PRACK message to the base station.

And step 10, the calling terminal reports the neighbor cell measurement report to the base station.

And step 11, the base station sends a PRACK/OK message to the calling terminal.

Step 12, the calling terminal sends an UPDATE message to the base station.

And step 13, the calling terminal reports the neighbor cell measurement report to the base station.

Step 14, the base station sends UPDATE completion (UPDATE/OK) message to the calling terminal.

And step 15, the calling terminal sends a RINGING message to the base station.

And step 16, the calling terminal reports the neighbor cell measurement report to the base station.

And step 17, the base station sends an INVITE/OK message to the calling terminal.

And step 18, the calling terminal sends an INVITE/ACK message to the base station.

And step 19, the calling terminal reports the neighbor cell measurement report to the base station.

Step 20, the base station sends an RRC Release (Release) message to the calling terminal.

The INVITE message sent by the calling terminal to the base station in step 1 carries the voice service type requested by the calling terminal. For example, if the INVITE message sent by the calling terminal includes a field of "5QI1", the voice service type requested by the calling terminal may be referred to as VoNR service. When receiving the INVITE message of the calling terminal, the base station determines that the voice service type requested by the calling terminal is a VoNR service based on a field including "5QI1" in the INVITE message, then the base station determines whether the base station supports the VoNR service, and sends 100try to the calling terminal under the condition that the base station supports the VoNR service, so as to determine that the calling terminal can request a network bearer of the VoNR service. Step 3 to step 18 are data interaction between the calling terminal and the base station in the process that the calling terminal requests the network bearer of the VoNR service. When the calling terminal sends the INVITE/ACK to the base station, the network bearing establishment between the calling terminal and the base station is completed.

In the process of establishing network load between the calling terminal and the base station, the calling terminal reports neighbor cell measurement reports to the base station. The neighbor cell measurement report includes the communication signal strength of the neighbor cell of the calling terminal. The base station determines whether the cell in which the calling terminal resides needs to be switched from the serving cell to the neighbor cell or not based on the communication signal strength of the neighbor cell and the communication signal strength of the serving cell in which the calling terminal currently resides. It will be appreciated that handover of a cell may result in loss of bearer between the terminal device and the base station. Particularly, in a 5G base station in which the base station is an independent networking mode, since a core network is configured with one base station, the base station where the neighbor cell of the calling terminal is located may not be the 5G base station, so if the resident cell of the calling terminal is switched to the neighbor cell, the bearer between the calling terminal and the base station is lost. This may result in failure of voice service establishment, affecting user experience.

Illustratively, as shown in fig. 2, the calling terminal 1 is in communication connection with the base station 2. The cell where the calling terminal 1 currently resides is cell 1, that is, the current serving cell of the calling terminal 1 is cell 1. The current neighbor cell of the calling terminal 1 includes cell 2, cell 3, cell 4, cell 5 and cell 6. Wherein cell 1, cell 2 and cell 3 belong to the same base station, i.e. station 2. Cell 4, cell 5 and cell 6 belong to the same base station, base station 3. The base station 2 is a 5G base station adopting independent networking. The VoNR service initiated by the calling terminal 1 can be supported. The base station 3 is a 4G base station and cannot support the VoNR service initiated by the calling terminal 1. In the process of establishing a voice service between the calling terminal 1 and the base station 2, if the communication signal strength of the cell 5 is greater than the communication signal strength of the cell 1, the base station 2 will generally instruct the calling terminal 1 to switch the resident cell from the cell 1 to the cell 5. However, since the cell 5 is a cell of the base station 3, the VoNR service is not supported. Therefore, if the resident cell of the calling terminal 1 is switched from the cell 1 to the cell 5, the bearer of the calling terminal 1 is lost, and the VoNR service is failed, which affects the user experience.

It should be understood that the flow of establishing a communication connection between the called terminal and the base station is similar to that of fig. 1, and will not be repeated here.

In view of this, the embodiment of the present application provides a method for establishing a voice service, where the terminal device obtains first information indicating a voice service type between the terminal device and the network device, and obtains second information indicating a communication signal strength of a cell where the terminal device resides at a current time when the voice service between the terminal device and the network device is a VoNR service, and then stops sending a measurement report to the network device when the signal strength of the cell where the terminal device resides at the current time is greater than a preset threshold value, so that the network device stops switching the cell where the terminal device resides based on the measurement report.

The following describes in detail the method for establishing a voice service according to the embodiment of the present application with reference to fig. 5 to 8.

Fig. 5 is a flow chart of a method for establishing a voice service according to an embodiment of the present application, as shown in fig. 5, where the method includes:

S101, the terminal equipment acquires first information.

Wherein the first information is used for indicating a voice service type between the terminal device and the network device.

The voice traffic type may include 5G voice calls, i.e., voNR traffic. A field for knowledge of the voice traffic type may be included in the information interacted between the terminal device and the network device. The terminal device may obtain the corresponding field from the information interacted with the network device, and determine the voice service types of the terminal device and the network device.

It should be understood that the terminal device may be a calling device or a called device, which is not limited in this embodiment of the present application.

Wherein the network device may refer to a base station, and illustratively, the network device may refer to a 5G base station. The network device may also refer to a system of base stations and a core network, and the network device may refer to a 5G base station and its corresponding core network, as an example.

The networking modes of the 5G base stations which should be connected comprise an independent networking mode and a dual-connection networking mode. Wherein, independent networking generally means that one base station is connected with one core network, and dual-connection networking generally means that two or more base stations are connected with one core network. Under the condition that the terminal equipment resides in the cell on the base station adopting the independent networking mode, when the terminal equipment needs to be switched to other cells, the situation that the load between the base station and the terminal equipment is lost is easy to occur because the number of the cells on one base station is small.

For example, in the case where the terminal device is a calling device, the terminal device may determine a voice service type between the terminal device and the network device based on an operation of making a call by the user. And carries a field indicating the type of voice service when the INVITE message is sent to the network device.

In an exemplary case where the terminal device is a called device, the terminal device may receive an INVITE message sent by the network device, and determine, according to a field carried in the INVITE message, a voice service type between the terminal device and the network device.

S102, acquiring second information under the condition that voice service between the terminal equipment and the network equipment is VoNR service.

The second information is used for indicating the signal strength of the resident cell of the terminal equipment at the current moment.

Generally, an INVITE message transmitted between a terminal device and a network device includes a field indicating a type of voice traffic between the terminal device and the network device. The terminal device or the network device may determine a voice traffic type between the terminal device and the network device based on the INVITE message.

For example, in the case where the terminal device is a calling device, the terminal device may determine a voice service type between the terminal device and the network device based on an operation of making a call by the user. For example, a user's operation to place a call indicates that the terminal device requests establishment of a VoNR service with the network device. The terminal device carries a field "5QI1" indicating the type of voice service when transmitting the INVITE message to the network device. After the network device receives the INVITE message, it is determined that the voice service type between the terminal device and the network device is VoNR service based on the field "5QI1".

For example, in the case where the terminal device is a called device, the terminal device may receive an INVITE message sent by the network device, where a field carried by the INVITE message is "5QI1". The terminal equipment determines the voice service type between the terminal equipment and the network equipment to be VoNR service according to the field '5 QI 1' carried by the INVITE message.

The terminal device typically needs to measure the signal strength of the communication signal between the terminal device and the network device at preset time intervals. For example, reference signal received power (Reference Signal Receiving Power, RSRP), received signal strength indication (Received Signal Strength Indicator, RSSI), received signal code power (Receive Signal Code Power, RSCP), reference signal received quality (Reference Signal Receiving Power, RSRQ), independent signal unit (Alone signal unit, ASU), signal-to-noise ratio (Signal to Interference Noise Ratio, SNR), or error vector magnitude (Error Vector Magnitude, EVM). These signals may generally be used to indicate the signal strength of the communication signals between the terminal device and the network device. The terminal device may determine a signal strength of the communication signal between the terminal device and the network device based on the signals.

And S103, stopping sending the measurement report to the network equipment by the terminal equipment under the condition that the signal strength of the resident cell at the current moment is greater than a preset threshold value.

The measurement report is used for indicating the signal strength of the cell where the terminal equipment is to reside. The cell to be camped on may include a cell that the terminal device can access, including a camped cell and a neighbor cell at the current time. Illustratively, as shown in fig. 4, the cells to be camped on include cell 1, cell 4, cell 5, cell 6, and cell n.

The preset threshold may be a threshold set by a user based on experience, and the terminal device can maintain good call quality when the signal strength of the camping cell at the current moment is greater than the preset threshold. It should be appreciated that when a terminal device switches cells, there are situations in which a bearer between the terminal device and the network device is lost. If the terminal equipment can keep good call quality, stopping switching the cell where the terminal equipment resides can reduce the risk of losing the bearer between the terminal equipment and the network equipment. Therefore, in the case where the signal strength of the camping cell at the current time is greater than the preset threshold, the terminal device stops sending the measurement report indicating the communication quality of the cell where the terminal device camps to the network device.

And S104, the network equipment stops switching the resident cell of the terminal equipment based on the measurement report.

In the case where the terminal device stops transmitting a measurement report indicating the communication quality of the cell in which the terminal device resides to the network device, the network device cannot determine whether to switch the cell based on the communication quality of the cell in which the terminal device currently resides. Therefore, the terminal equipment does not switch the cell where the terminal equipment currently resides under the condition of keeping good call quality, and the risk of losing the load between the terminal equipment and the network equipment in the process of switching the cell is avoided.

According to the method for establishing the voice service provided by the embodiment of the application, the terminal equipment acquires the first information indicating the voice service type between the terminal equipment and the network equipment, acquires the second information indicating the communication signal strength of the cell where the terminal equipment resides at the current moment when the voice service between the terminal equipment and the network equipment is the VoNR service, and stops sending the measurement report to the network equipment when the signal strength of the cell where the terminal equipment resides at the current moment is greater than the preset threshold value, so that the network equipment stops switching the cell where the terminal equipment resides based on the measurement report.

In general, in the process of establishing a voice service between a terminal device and a network device, a situation in which a bearer is lost due to cell handover is liable to occur. After the voice service has been established successfully, there are fewer cases where bearer loss due to cell handover occurs. Therefore, after the voice service has been established successfully, the terminal device resumes sending the measurement report to the network device, so that the network device can adjust the communication mode between the network device and the terminal device in real time based on the measurement report. Described in detail below by way of the embodiment shown in fig. 6.

Fig. 6 is a flow chart of another method for establishing a voice service according to an embodiment of the present application, as shown in fig. 6, where the method includes:

s201, the terminal equipment acquires first information.

S202, acquiring second information under the condition that voice service between the terminal equipment and the network equipment is VoNR service.

And S203, stopping sending the measurement report to the network equipment by the terminal equipment under the condition that the signal strength of the resident cell at the current moment is greater than a preset threshold value.

In one possible scenario, the network device refers to a base station, and the base station accesses the communication network in an independent networking manner.

It should be appreciated that 5G base stations accessing the communication network by way of independent networking are typically a base station and a core network. Illustratively, as shown in fig. 2, the base station 2 is a 5G base station adopting an independent networking manner. The VoNR service initiated by the calling terminal 1 can be supported. The base station 3 is a 4G base station and cannot support the VoNR service initiated by the calling terminal 1. In the process of establishing a voice service between the calling terminal 1 and the base station 2, if the communication signal strength of the cell 5 is greater than the communication signal strength of the cell 1, the base station 2 typically instructs the calling terminal 1 to switch the resident cell from the cell 1 to the cell 5 in the conventional technology. However, since the cell 5 is a cell of the base station 3, the VoNR service is not supported. Therefore, if the resident cell of the calling terminal 1 is switched from the cell 1 to the cell 5, the bearer of the calling terminal 1 is lost, and the VoNR service is failed, which affects the user experience. In the embodiment of the present application, in the process of establishing a voice service between the calling terminal 1 and the base station 2, if the communication signal strength of the cell 5 is greater than the communication signal strength of the cell 1, and at the same time, if the signal strength of the resident cell at the current moment is greater than the preset threshold, the terminal device stops sending the measurement report to the network device. Therefore, the network device stops switching the resident cell of the terminal device, so that the bearer between the network device and the terminal device is not lost due to the switching of the cell.

According to the method for establishing the voice service, provided by the embodiment of the application, the first information indicating the voice service type between the terminal equipment and the network equipment is obtained through the terminal equipment, the second information indicating the communication signal strength of the resident cell of the terminal equipment at the current moment is obtained under the condition that the voice service between the terminal equipment and the network equipment is VoNR service, and then the measurement report is stopped from being sent to the network equipment under the condition that the signal strength of the resident cell at the current moment is greater than the preset threshold value, so that the network equipment stops switching the resident cell of the terminal equipment based on the measurement report, wherein the network equipment is a 5G base station, and the 5G base station is accessed into a communication network in an independent networking mode. Because the 5G base stations which are independently networked generally correspond to a core network, the cells which can be accessed by the terminal equipment generally belong to one base station, that is, the number of the cells which can be accessed by the terminal equipment is small, so that the cells are switched between the 5G base stations which are independently networked and the terminal equipment, and the situation that the load of the base stations and the terminal equipment is lost is more likely to occur. Therefore, under the condition that the signal strength of the resident cell at the current moment is larger than a preset threshold value, the 5G base station stops sending the measurement report to the 5G base station, so that the 5G base station stops switching the resident cell of the terminal equipment based on the measurement report, the risk of bearing loss between the terminal equipment and the 5G base station can be more effectively reduced, the establishment stage of voice service can be further more effectively reduced, and the problem of communication establishment failure caused by cell switching occurs.

Optionally, S204, when the signal strength of the camping cell at the current moment is less than or equal to the preset threshold, the measurement report is sent to the network device, so that the network device determines whether to switch the camping cell of the terminal device based on the measurement report.

Under the condition that the signal strength of the resident cell at the current moment is smaller than or equal to a preset threshold value, the communication quality of the terminal equipment at the current resident cell is poor, and the voice call requirement cannot be met. Therefore, under the condition that the signal strength of the resident cell at the current moment is smaller than or equal to a preset threshold value, the terminal equipment continuously sends a measurement report to the network equipment, so that the network equipment can determine whether a neighbor cell with better communication quality than the resident cell exists or not based on the measurement report, and the current resident cell is switched to the neighbor cell under the condition that the neighbor cell with better communication quality exists, so that the communication quality between the terminal equipment and the network equipment is ensured.

According to the voice service establishing method provided by the embodiment of the application, the first information indicating the voice service type between the terminal equipment and the network equipment is obtained through the terminal equipment, the second information indicating the signal strength of the resident cell of the terminal equipment at the current moment is obtained under the condition that the voice service between the terminal equipment and the network equipment is VoNR service, and then the measurement report is sent to the network equipment under the condition that the signal strength of the resident cell at the current moment is smaller than or equal to the preset threshold value, so that the network equipment determines whether to switch the resident cell of the terminal equipment based on the measurement report, and therefore, the network equipment can switch the terminal equipment to a neighbor cell with good communication quality through the measurement report under the condition that the communication quality of the current resident cell of the terminal equipment is poor, and further normal operation of the terminal equipment is ensured.

S205, the network device stops switching the camping cell of the terminal device based on the measurement report.

S206, when the voice service with the network equipment is established successfully, the measurement report is restored to be sent to the network equipment.

As can be seen from the flowchart shown in fig. 1, when a voice service is successfully established between a terminal device and a network device, the terminal device sends an INVITE/ACK to the network device. At this time, the voice service has been successfully established between the terminal device and the network device, and other service communication can be performed between the terminal device and the network device. In this case, the terminal device resumes sending the measurement report to the network device, which corresponds to the case where other traffic communication is performed between the terminal device and the network device, the network device can switch the camping cell of the terminal device based on the measurement report so that the camping cell of the terminal device is always the cell with the best communication quality.

According to the voice service establishment method provided by the embodiment of the application, the first information indicating the voice service type between the terminal equipment and the network equipment is obtained through the terminal equipment, the second information indicating the communication signal strength of the resident cell of the terminal equipment at the current moment is obtained under the condition that the voice service between the terminal equipment and the network equipment is VoNR service, then the measurement report is stopped from being sent to the network equipment under the condition that the signal strength of the resident cell at the current moment is larger than the preset threshold value, and the measurement report is restored to be sent to the network equipment when the voice service between the terminal equipment and the network equipment is successfully established. When the voice service between the terminal device and the network device is successfully established, other services are usually communicated between the terminal device and the network device, in this case, since the terminal device resumes sending the measurement report to the network device, the network device can switch the residence cell of the terminal device based on the measurement report, so that the residence cell of the terminal device always has the best communication quality, and the communication quality of the network device and the terminal device when communicating other services is improved.

In a possible case, the terminal device is a calling terminal, and in the process of establishing the voice service with the network device, the calling terminal needs to determine the type of the voice service to be established between the calling terminal and the network device according to the operation of dialing the call by the user. And then determining whether to stop sending measurement reports to the network device based on the voice service type. Described in detail below by way of the embodiment shown in fig. 7.

For example, the calling terminal may determine the voice service type between the calling terminal and the network device according to the operation of the user making a call.

S302, the calling terminal sends first information to the network equipment.

S303, the calling terminal determines whether the voice service type between the calling terminal and the network equipment is VoNR service or not based on the first information, if so, S304 is executed; if not, S309 is performed.

S304, the calling terminal acquires the second information.

The second information is used for indicating the signal strength of the resident cell of the calling terminal at the current moment.

S305, the calling terminal equipment determines whether the signal strength of the resident cell at the current moment is larger than a preset threshold value, if so, S306 is executed; if not, S309 is performed.

S306, the calling terminal stops sending the measurement report to the network equipment.

And then determining whether to stop sending measurement reports to the network device based on the voice service type. Described in detail below by way of the embodiment shown in fig. 8.
