This application claims the priority of the Chinese patent application with the application number 202111183749.0 and the application title "data processing method, device, terminal equipment and storage medium" filed with the China Patent Office on October 11, 2021, the entire contents of which are incorporated by reference in this application.

technical field

Background technique

With the rapid development of mobile communication, the fifth-generation mobile communication technology (New Radio, NR, commonly known as "5G") has gradually replaced the fourth-generation mobile communication technology (Long Term Evolution, LTE, commonly known as "4G"). However, at present, most 5G networks cannot carry voice services, and the Evolved Packet System Fallback (EPS Fallback) method is usually used to solve this problem. When the terminal currently resides in a 5G cell, if the terminal initiates or receives a voice service request, the network side can drop the voice service from the 5G network to the 4G network.

However, in order to speed up the construction and improvement of 5G, mobile terminals on the 5G network will perform 5G measurements in real time (for example, measuring 5G cells, 5G signals, etc.), so that after the terminal is handed over by EPS Fallback or redirected to the 4G network, the terminal will still be on the 4G network. Real-time 5G measurement is performed on the 4G network, and a different system measurement report is generated. The terminal sends the different system measurement report to the network side, which will cause the terminal to switch or redirect the 4G network back to the 5G network, which will cause this voice service fail.

The mobile terminal can also be a wearable device. Wearable devices can also be called wearable smart devices, which is a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only a hardware device, but also achieve powerful functions through software support, data interaction, and cloud interaction. Generalized wearable smart devices include full-featured, large-sized, complete or partial functions without relying on smart phones, such as smart watches or smart glasses, etc., and only focus on a certain type of application functions, and need to be used in conjunction with other devices such as smart phones , such as various smart bracelets and smart jewelry for physical sign monitoring.

In this application scenario, first, the electronic terminal device 13 registers and resides in a 5G cell, so that the electronic terminal device 13 can enjoy the voice service and data service brought by the 5G network. Among them, the voice service usually refers to the voice call and video call service based on the cellular network, for example, the user answers the voice call, video call, etc.; the data service usually refers to the mobile communication service based on data transmission and information interaction, such as the user using Scan code payment, browser search, etc. Regardless of whether the electronic terminal device 13 executes a voice service or a data service, it needs to have a corresponding bearer protocol for implementation, for example, a voice service corresponds to a voice service bearer protocol, and a data service corresponds to a data service bearer protocol. However, because the current 5G infrastructure is not yet perfect, most 5G networks do not have voice service bearer protocols, such as the 5G voice service bearer protocol VoNR. In order to facilitate users to use terminals on the 5G network for voice services, EPS Fallback is usually used to switch or redirect the terminals from the 5G network to the 4G network, so that the terminals on the 5G network can carry voice services through VoLTE under the 4G network to realize voice calls .

The process of performing EPS Fallback to the 4G network for the electronic terminal device 13 of the 5G network that does not support VoNR will be described below. During the establishment of the IMS call connection, the electronic terminal device 13 initiates a service request for the voice service, and the electronic terminal device 13 completes the RRC (Radio Resource Control, radio resource control) connection establishment with the 5G access network. After the RRC connection is established, the electronic terminal device 13 sends the service request to the 5G core network, so that the authentication and NAS encryption negotiation process is completed between the electronic terminal device 13 and the 5G core network. The electronic terminal device 13 sends an INVITE message to the 5G core network to request the establishment of a voice session. Afterwards, the 5G access network sends a switching or redirection request to the 5G core network according to the switch parameter configuration and the capability of the electronic terminal device 13. After the handover or redirection request is sent successfully, the 5G core network forwards the UE context information to the 4G core network, and the 4G core network initiates a handover or redirection request to the 4G access network. After receiving the handover or redirection request, the 4G access network sends a response to the 4G core network of receiving the handover or redirection request. After receiving the response, the 4G core network forwards the successful response message of the 4G access network to the handover or redirection request to the 5G core network, and the 5G core network initiates a handover or redirection command to the 5G access network after receiving the successful response message , the 5G access network initiates a switching or redirection command to the electronic terminal device 13, and the electronic terminal device 13 switches or redirects to a cell of the 4G network, so that the electronic terminal device 13 can establish an IMS call with another terminal under the 4G network, thereby The electronic terminal device 13 of the 5G network can realize voice service through VoLTE under the 4G network.

However, in order to speed up the construction and improvement of 5G, the terminals of the 5G network will perform 5G measurements in real time (for example, measuring 5G cells, 5G signals, etc.), so that the terminals supporting 5G can access the 5G network in a high-quality 5G environment in a timely manner . In this way, after the electronic terminal device 13 switches or redirects to the 4G network in EPS Fallback, the electronic terminal device 13 will still perform 5G measurement under the 4G network and generate a different system measurement report. For example, the 4G access network sends a different-system B1 event measurement command to the electronic terminal device 13. In this scenario, the different-system B1 event measurement is 5G network measurement, such as measuring 5G neighboring cells and 5G signals. It should be noted that in other scenarios, the inter-system B1 event is not limited to 5G network measurement, but can also be 4G/3G/2G measurement. In addition, in this scenario, the 4G access network can also issue a B2 event parallel to the B1 event to the electronic terminal device 13, and the B2 event can be other 5G measurement tasks, or 3G and 2G measurement tasks.

After the electronic terminal equipment 13 completes the 5G measurement, if the measurement results meet the conditions, for example, there is an accessible 5G cell, the signal strength of the 5G cell meets the access conditions, and the signal quality of the 5G cell meets the access conditions, etc., the 4G access network Receiving the different system measurement report from the electronic terminal device 13, and issuing an instruction instructing the electronic terminal device 13 to switch or redirect back to the 5G network will cause the electronic terminal device 13 to switch or redirect the 4G network back to the 5G network, thereby As a result, the voice service failed.

In view of the above problems, the embodiment of the present invention proposes a data processing method, device, terminal equipment, and storage medium. Through the method of the embodiment of the present invention, when the terminal establishes an IMS call connection, the terminal of the 5G network is restricted to re-switch the 4G network Or redirect to the 5G network, so that the terminal on the 5G network can establish an IMS call under the 4G network, so that the terminal can successfully perform voice services.

Fig. 2 is the flowchart of a kind of data processing method that the embodiment of the present invention provides, and this data processing method can be applied to electronic terminal equipment UE, and this UE can be to have Subscriber Identity Module (Subscriber Identity Module, SIM) or global subscriber identity module (Universal Subscriber Identity Module, USIM) mobile communication terminal, this data processing method can also be applied to 5G network.

As shown in Figure 2, the data processing method includes:

Step 210: During the establishment of the IP Multimedia Subsystem IMS call connection, it is detected whether there is an EPS Fallback process.

According to the foregoing, voice services generally refer to voice call and video call services based on a cellular network, for example, a user receives a voice call, a video call, and the like. Taking the scenario where a user answers or makes a voice call as an example, the user's UE can act as a calling terminal or a called terminal to establish an IMS call connection with another terminal. After the IMS call connection is successfully established, the user can implement a voice call.

According to the description in Figure 1, for a UE on a 5G network that does not support voice services, since it does not have the bearer protocol VoNR of 5G voice services, it needs to fall back to the 4G network through EPS Fallback, and carry VoLTE through 4G voice services to realize voice calls; Specifically, for a UE on a 5G network that supports voice services, if it has the bearer protocol VoNR for 5G voice services, it can directly implement voice calls under the bearer of VoNR without falling back to the 4G network through EPS Fallback.

In some embodiments, during the establishment of the IP Multimedia Subsystem IMS call connection, it may be detected whether there is an EPS Fallback procedure. Optionally, the UE may detect whether there is an EPS Fallback process in the current process when receiving or sending the INVITE message. It can be understood that for a UE that supports VoNR to carry voice services, the UE detects that there is no EPS Fallback process; for a UE that does not support VoNR to carry voice services, the UE detects that there is an EPS Fallback process.

It should be noted that the EPS Fallback in the embodiments of the present invention is all under the premise that the UE meets the conditions for executing the EPS Fallback, that is, the measurement result of the inter-system measurement report indicates that the UE can execute the EPS Fallback, for example, the UE capability meets the requirements for executing the EPS Fallback, The UE measures that there are 4G network neighbors that can be handed over or redirected.

Step 220, if it is detected that the EPS Fallback process exists, restrict the re-switching of the 4G network or redirect it to the 5G network.

According to the description in Figure 1, since 5G measurement is performed in real time, after the UE falls back to the 4G network through EPS Fallback, the UE will still perform 5G measurement on the 4G network. The different system measurement report of the measurement result is sent to the 4G access network, so that the 4G access network will send an instruction to the UE to switch or redirect back to the 5G network, resulting in the UE being unable to establish an IMS call connection.

In some embodiments, the UE may restrict re-handover or redirection of the 4G network to the 5G network in various ways. For example, the UE can implement this by suspending 5G measurement, issuing 5G disabling instructions, and restricting the sending of different system measurement reports. For more details about the UE restricting the re-handover or redirection of the 4G network to the 5G network, refer to the relevant descriptions in FIG. 3 and FIG. 4 .

In some embodiments, if the UE detects that there is no EPS Fallback procedure, the UE may not be restricted from re-switching the 4G network or redirecting to the 5G network. For example, a UE registered and camped in a 4G cell can switch or redirect to a 5G network after searching for a 5G neighbor to enjoy better services of the 5G network.

Through the above method, during the establishment of an IMS call connection between the UE and another terminal, the UE can first detect whether there is an EPS Fallback process in the current process, and then restrict 4G network re-switching or redirect to 5G after detecting the existence of the EPS Fallback process operation of the network. On the one hand, it can effectively prevent the voice call failure of the UE under the 4G network due to re-handover or redirection to the 5G network; on the other hand, if it is detected that there is no EPS Fallback process, the UE will not perform the above-mentioned restriction operations, It can prevent UEs supporting VoNR from being unable to re-switch or redirect to the 5G network under the 4G network due to misjudgment, and unable to enjoy the high-quality services of the 5G network.

FIG. 3 is a flowchart of a data processing method provided by another embodiment of the present invention. As shown in FIG. 3 , step 220 can be implemented through step 2210 .

Step 2210, restricting the UE to measure a 5G network cell based on the 4G network, so as to restrict the network side from sending an instruction to re-switch or redirect the 4G network to the 5G network to the UE according to the measurement result.

In some embodiments, the 5G network may further include a network side, and the network side may include an access network and a core network, so that the UE may establish a communication connection with the network side. Optionally, the network side may include an access network and a core network. Taking the 5G network as an example, the network side may include a 5G access network and a 5G core network. The UE may establish a communication connection with the 5G access network, and establish a communication connection with the 5G core network through the 5G access network.

In some embodiments, the UE may restrict the UE to measure 5G network cells based on the 4G network, so as to restrict the network side from sending instructions to the UE to re-switch or redirect the 4G network to the 5G network. Due to the real-time nature of the UE's 5G measurement, the UE that falls back to the 4G network through EPS Fallback can suspend the 5G measurement during the establishment of the IMS call connection, that is, suspend the UE from measuring the 5G network cell based on the 4G network, so that the UE will not obtain any information about the 5G network. Network data, such as 5G cell distribution, 5G signal quality, 5G signal strength, etc. It can be understood that since the 5G measurement is suspended, the UE will not send the inter-system measurement report to the network side, so the network side will not send an instruction to the UE to re-switch or redirect the 4G network to the 5G network based on the measurement result.

Through the above method, during the establishment of an IMS call connection between the UE and another terminal, by restricting the UE to measure 5G network cells based on the 4G network, the UE will not obtain any data about the 5G network, and the network side will not receive the UE's different system information. Measurement report, so that the network side will not send instructions to the UE to re-switch or redirect back to the 5G network, preventing the UE from failing voice calls due to the 5G network that does not support VoNR.

FIG. 4 is a flowchart of a data processing method provided by another embodiment of the present invention. As shown in FIG. 4 , step 220 can be implemented through step 2220 .

Step 2220, restricting the UE from sending the obtained different-system measurement report to the network side, so as to restrict the network side from sending instructions to the UE to re-switch or redirect the 4G network to the 5G network according to the measurement results .

According to the above, after receiving the 5G inter-system measurement report sent by the UE on the 4G network, the 4G access network will send an instruction to the UE to re-handover or redirect back to the 5G network, so that the UE will re-handover or redirect back to the network that does not support VoNR. 5G network, causing the voice call to fail.

In some embodiments, the UE may be restricted from sending the obtained inter-system measurement report to the network side in various ways. For example, before sending the different-system measurement report to the network side, the UE may issue an instruction to intercept the different-system measurement report. For another example, before sending the different system measurement report to the network side, the UE may clear the data of the different system measurement report. In this way, the network side cannot receive the 5G inter-system measurement report reported by the UE from the 4G network, and the network side can be restricted from sending instructions to the UE to re-switch or redirect the 4G network to the 5G network.

Through the above method, during the establishment of an IMS call connection between the UE and another terminal, by restricting the UE from sending the obtained different system measurement report to the network side, the network side will not receive the UE's different system measurement report, so that the network side will not Send an instruction to the UE to re-switch or redirect back to the 5G network to prevent the UE from failing the voice call due to the 5G network that does not support VoNR.

It should be noted that a 5G measurement performed by the UE corresponds to a different system measurement report. Since the 5G measurement is performed in real time, when the UE falls back to the 4G network through EPS Fallback and establishes an IMS call connection with another terminal, whether it is Whether to restrict the UE to measure 5G network cells based on the 4G network, or to restrict the UE to send the obtained inter-system measurement report to the network side, neither method will have a great impact on 5G real-time measurement.

FIG. 5 is a flowchart of a data processing method provided by another embodiment of the present invention. As shown in FIG. 5 , after step 220 is performed, step 510 may also be performed.

Step 510, when the establishment of the IMS call connection succeeds or fails, releasing the restriction on re-handover or redirecting the 4G network to the 5G network.

Taking the scenario where the user makes a voice call as an example, the success of the IMS call connection establishment may be the call success, and the failure of the IMS call connection establishment may be the call failure. Correspondingly, the IMS call connection establishment period may be before the UE call success and call failure.

In some embodiments, when the IMS call connection is established successfully, the UE may release the restriction on re-handover or redirection from the 4G network to the 5G network. Wherein, the object to be restricted may be the UE that has performed the restriction operation such as step 220 or step 2210 or step 2220.

In some embodiments, the successful establishment of the IMS call connection may include that the UE sends or receives an acknowledgment message that the IMS call connection is successfully established. Wherein, the confirmation message may be an ACK message. For example, when the UE receives or sends the ACK message indicating that the IMS call connection is successfully established, it means that the UE can confirm that the current IMS call connection is successfully established. Afterwards, the UE may release the restriction of re-switching or redirecting the 4G network to the 5G network as in step 2210 or step 2220 . For example, the UE can stop suspending the 5G measurement, so that the UE can continue to measure 5G network cells based on the 4G network. For another example, the UE may cancel the interception instruction for the subsequent different-system measurement report, or no longer set the clearing operation for the subsequent different-system measurement report.

In some embodiments, the failure to establish the IMS call connection may include that the UE receives a response indicating that the IMS call connection has failed to be established, or the UE detects a scenario indicating that the IMS call connection has failed to be established.

In some embodiments, the response indicating that the establishment of the IMS call connection fails may be a failure response in a specific protocol. For example, request failure response, server failure response, global error response, etc. in protocol rfc3261. For example, response 400: bad request (bad request), response 504: server time-out (server timeout), response 606: not acceptable (unacceptable), etc.

In some embodiments, the scenario where the IMS call connection fails to be established may be a related scenario where the UE falls back to the 4G network abnormally. For example, it may include that the UE fails to register or camp on the current 4G cell, or the signal quality or strength of the current 4G network is not good.

When the UE receives the above response indicating that the IMS call connection fails to be established, or detects a scenario indicating that the IMS call connection fails to be established, it means that the UE can confirm that the current IMS call connection fails to be established. Afterwards, similar to the successful establishment of the IMS call connection, the UE may release the restriction on re-switching or redirecting the 4G network to the 5G network as in step 2210 or step 2220 . For example, the UE can stop suspending the 5G measurement, so that the UE can continue to measure 5G network cells based on the 4G network. For another example, the UE may cancel the interception instruction for the subsequent different-system measurement report, or no longer set the clearing operation for the subsequent different-system measurement report.

Through the above method, when the IMS call connection is established successfully or fails, the UE can promptly and accurately release the restrictions on re-switching or redirecting the 4G network to the 5G network, so that the UE can continue to perform real-time calls while the IMS call connection is not being established. 5G measurement, so as not to affect the construction and improvement of 5G. Moreover, the data processing method of the present invention can be applied to any one of the two terminals establishing an IMS call, and does not involve complex communication between multiple terminals or multiple modules, so that the UE can perform the method more conveniently and efficiently.
