Description

Data processing method, device, terminal equipment and storage medium

[ technical field ] A method for producing a semiconductor device

The embodiment of the application relates to the technical field of communication, and in particular relates to a data processing method and device, a terminal device and a storage medium.

[ background of the invention ]

With the rapid development of mobile communication, a fifth generation mobile communication technology (New Radio, NR, colloquially referred to as "5G") has gradually replaced a fourth generation mobile communication technology (Long Term Evolution, LTE, colloquially referred to as "4G"). However, most 5G networks cannot carry voice traffic, and an evolved packet system Fallback (EPS Fallback) method is usually used to solve the problem. When the terminal currently resides in the 5G cell, if the terminal initiates or receives a voice service request, the network side may drop the voice service from the 5G network back to the 4G network for proceeding.

However, in order to accelerate the construction and improvement of 5G, the mobile terminal of the 5G network may perform 5G measurement in real time (for example, measure a 5G cell, a 5G signal, etc.), so that after the terminal switches or redirects to the 4G network in the EPS Fallback, the terminal may still perform real-time 5G measurement in the 4G network, and generate a measurement report of the different system, and the terminal sends the measurement report of the different system to the network side, so that the terminal switches or redirects the 4G network back to the 5G network, thereby causing the failure of the voice service.

[ summary of the invention ]

In order to solve the above problem, embodiments of the present invention provide a data processing method, an apparatus, a terminal device, and a storage medium, which improve a success rate of implementing a voice service in a 5G network.

In a first aspect, the present application provides a data processing method, applied to an electronic terminal device UE, applied to a 5G network, the method including:

during the establishment of an IP Multimedia Subsystem (IMS) call connection, detecting whether an evolved packet Fallback (EPS Fallback) flow exists, wherein the EPS Fallback flow switches or redirects the current 5G network to a 4G network;

and if the EPS Fallback flow is detected to exist, the 4G network is limited to be switched again or redirected to a 5G network.

Therefore, the success rate of the terminal for realizing the voice service in the 5G network can be improved, and the situation that the UE supporting the voice service cannot be switched again or redirected to the 5G network under the 4G network due to misjudgment and cannot enjoy the high-quality service of the 5G network can be prevented.

In a possible implementation manner, the 5G network further includes a network side, where the UE establishes a communication connection with the network side, and if it is detected that the EPS Fallback procedure exists, the restricting to re-switch or redirect the 4G network to the 5G network includes:

and limiting the UE to measure a 5G network cell based on the 4G network so as to limit the network side to send an instruction for re-switching or redirecting the 4G network to the 5G network to the UE according to the measurement result.

Therefore, the UE cannot acquire any data about the 5G network, and the network side cannot receive the inter-system measurement report of the UE, so that the network side cannot send a command of re-switching or redirecting back to the 5G network to the UE, and the voice call failure of the UE is prevented.

In a possible implementation manner, the 5G network further includes a network side, where the UE establishes a communication connection with the network side, and if it is detected that the EPS Fallback procedure exists, the limiting the network side to re-switch or redirect the 4G network to the 5G network includes:

and limiting the UE to send the obtained measurement report of the abnormal system to the network side so as to limit the network side to send an instruction for re-switching or redirecting the 4G network to the 5G network to the UE according to the measurement result, wherein the measurement report of the abnormal system is obtained by measuring the 5G network cell based on the 4G network.

Therefore, the network side cannot receive the inter-system measurement report of the UE, so that the network side cannot send a command of switching again or redirecting back to the 5G network to the UE, and the voice call failure of the UE is prevented.

In one possible implementation, the method further includes:

and when the IMS call connection is successfully established or fails, releasing the restriction of re-switching or redirecting the 4G network to the 5G network.

Therefore, the UE can timely and accurately remove the restriction of re-switching or redirecting the 4G network to the 5G network when the IMS call connection is successfully established or fails, so that the UE can continuously carry out real-time 5G measurement when the UE is not in the period of establishing the IMS call connection, and the construction and the perfection of the 5G are not influenced.

In one possible implementation manner, the successful establishment of the IMS call connection includes that the UE sends or receives an acknowledgement message that the IMS call connection establishment is successful;

the IMS call connection establishment failure comprises that the UE receives a response indicating the IMS call connection establishment failure, or the UE detects a scene indicating the IMS call connection establishment failure.

Therefore, the UE can accurately judge whether the IMS call connection is established successfully or unsuccessfully, and therefore the efficiency and the accuracy of subsequently releasing the limitation of re-switching or redirecting the 4G network to the 5G network can be improved.

Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable intelligent device has the advantages that the generalized wearable intelligent device is complete in function and large in size, can realize complete or partial functions without depending on a smart phone, such as a smart watch or smart glasses, and only is concentrated on a certain application function, and needs to be matched with other devices such as the smart phone for use, such as various smart bracelets for monitoring physical signs, smart jewelry and the like.

In the present application scenario, first, the electronic terminal device 13 registers and resides in the 5G cell, so that the electronic terminal device 13 can enjoy the voice service and the data service brought by the 5G network. The voice service generally refers to voice call and video call services based on a cellular network, such as a user receiving a voice call, a video call, and the like; the data service generally refers to a mobile communication service using data transmission and information interaction as technologies, such as code scanning payment by a user using a network, browser search, and the like. Whether the electronic terminal device 13 executes the voice service or the data service, it needs to have a corresponding bearer protocol to implement, for example, a voice service bearer protocol corresponding to the voice service and a data service bearer protocol corresponding to the data service. However, most 5G networks do not have a voice service bearer protocol, such as the voice service bearer protocol VoNR, because the existing 5G infrastructure is not perfect enough. In order to facilitate a user to use a terminal of a 5G network to perform a voice service, an EPS Fallback is usually used to switch or redirect the terminal from the 5G network to a 4G network, so that the terminal of the 5G network can carry the voice service through VoLTE in the 4G network to implement a voice call.

The procedure for the electronic terminal device 13 of the 5G network that does not support the VoNR to execute the EPS Fallback to 4G network will be described below. During the IMS call connection establishment, the electronic terminal device 13 initiates a service request of a voice service, and the electronic terminal device 13 and the 5G access network complete RRC (Radio Resource Control) connection establishment. 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 processes between the electronic terminal device 13 and the 5G core network are completed. And the electronic terminal equipment 13 sends the INVITE message to the 5G core network to request to establish the voice session, and then the 5G access network judges to send a switching or redirection request to the 5G core network according to the switch parameter configuration and the capability of the electronic terminal equipment 13. After the switching or redirection request is successfully sent, the 5G core network forwards the UE context information to the 4G core network, and the 4G core network initiates the switching or redirection request to the 4G access network. And after receiving the switching or redirection request, the 4G access network sends a response of receiving the switching or redirection request to the 4G core network. After receiving the response, the 4G core network forwards a successful response message of the 4G access network to the switching or redirection request to the 5G core network, the 5G core network initiates a switching 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, and the electronic terminal device 13 of the 5G network can implement a voice service under the 4G network through VoLTE.

However, in order to speed up the construction and improvement of 5G, the terminal of the 5G network may perform 5G measurement (e.g., measure 5G cell, 5G signal, etc.) in real time, so that the terminal supporting 5G can timely access the 5G network in a good-quality 5G environment. In this way, after the electronic terminal device 13 switches or redirects to the 4G network in the EPS Fallback, the electronic terminal device 13 still performs 5G measurement in the 4G network, and generates a measurement report of the different system. For example, the 4G access network issues an inter-system B1 event measurement instruction to the electronic terminal device 13, and in this scenario, the inter-system B1 event measurement is 5G network measurement, for example, measuring a 5G neighboring cell, a 5G signal, and the like. It should be noted that in other scenarios, the inter-system B1 event is not limited to 5G network measurement, but may also be 4G/3G/2G measurement. In addition, in this scenario, the 4G access network may also issue a B2 event parallel to the B1 event to the electronic terminal device 13, where the B2 event may be other 5G measurement tasks, or measurement tasks of 3G and 2G.

After the electronic terminal device 13 completes the 5G measurement, if the measurement result meets the condition, for example, the signal strength of the accessible 5G cell and the 5G cell meets the access condition, the signal quality of the 5G cell meets the access condition, and the like, the 4G access network receives the inter-system measurement report from the electronic terminal device 13, and sends an instruction indicating the electronic terminal device 13 to switch or redirect back to the 5G network, so that the electronic terminal device 13 can switch or redirect the 4G network back to the 5G network, thereby causing the voice service to fail.

In view of the foregoing problems, embodiments of the present invention provide a data processing method, an apparatus, a terminal device, and a storage medium, where by the method in the embodiments of the present invention, during an IMS call connection is established by a terminal, the terminal of a 5G network is restricted to re-switch or redirect the 4G network to the 5G network, so that the terminal of the 5G network can establish an IMS call under the 4G network, and the terminal is enabled to successfully perform a voice service.

Fig. 2 is a flowchart of a data processing method according to an embodiment of the present invention, where the data processing method may be applied to an electronic terminal device UE, where the UE may be a mobile communication terminal having a Subscriber Identity Module (SIM) or a Universal Subscriber Identity Module (USIM), and the data processing method may also be applied to a 5G network.

As shown in fig. 2, the data processing method includes:

step 210, during the establishment of the IMS call connection, detecting whether an EPS Fallback flow exists.

In light of the foregoing, voice traffic generally refers to voice call and video call traffic over cellular networks, such as a user receiving a voice call, a video call, and so on. Taking a scenario that a user answers or dials a voice call as an example, the UE of the user can be used as a calling terminal or a called terminal to establish an IMS call connection with another terminal, and when the IMS call connection is successfully established, the user can implement a voice call.

According to the description in fig. 1, for a UE in a 5G network that does not support a voice service, since the UE does not have a bearer protocol VoNR of the 5G voice service, the UE needs to fall back to a 4G network through an EPS Fallback and carries VoLTE through the 4G voice service to implement a voice call; correspondingly, for the UE of the 5G network supporting the voice service, the UE has the bearer protocol VoNR of the 5G voice service, and can directly implement the voice call under the VoNR bearer without going back to the 4G network through the EPS Fallback.

In some embodiments, during the establishment of an IP multimedia subsystem IMS call connection, it may be detected whether an evolved packet Fallback, EPS Fallback, flow exists. Optionally, the UE may detect whether an EPS Fallback procedure exists in the current process when receiving or sending the INVITE message. It can be understood that, for a UE supporting a VoNR voice-bearing service, the UE detects that there is no EPS Fallback procedure; for the UE not supporting the VoNR voice service, the UE will detect that there is an EPS Fallback procedure.

It should be noted that, in the embodiment of the present invention, the EPS Fallback is on the premise that the UE satisfies the condition of executing the EPS Fallback, that is, the measurement result of the measurement report of the different system indicates that the UE can execute the EPS Fallback, for example, the UE capability satisfies the condition of executing the EPS Fallback, the UE measures that there is a 4G network neighboring cell that can be switched or redirected, and the like.

And step 220, if the EPS Fallback flow is detected to exist, the 4G network is limited to be switched again or redirected to the 5G network.

According to the description in fig. 1, since the 5G measurement is performed in real time, after the UE falls back to the 4G network through the EPS Fallback, the UE still performs the 5G measurement in the 4G network, and if the UE finds a 5G neighboring cell through the 5G measurement, the UE sends a measurement report of the different system including the measurement result to the 4G access network, so that the 4G access network sends a command of switching or redirecting back to the 5G network to the UE, and the UE cannot establish the IMS call connection.

In some embodiments, the UE may restrict the 4G network from being re-handed over or redirected to the 5G network in a number of ways. For example, the UE may suspend 5G measurement, issue a 5G disable instruction, and limit sending inter-system measurement reports. For more details about the UE restricting the re-handover or redirection of the 4G network to the 5G network, see fig. 3 and the related description of fig. 4.

In some embodiments, if the UE detects that there is no EPS Fallback procedure, the UE may not restrict the 4G network from being re-switched or redirected to the 5G network. For example, a UE registered and camped on a 4G cell may be handed over or redirected to a 5G network after searching for a 5G neighbor cell, in order to enjoy better service of the 5G network.

Through the method, during the IMS call connection between the UE and the other terminal, the UE can detect whether the EPS Fallback flow exists in the current process, and after the EPS Fallback flow is detected to exist, the operation of limiting the 4G network to be switched again or redirected to the 5G network is performed. On one hand, the method can effectively prevent the failure of voice call caused by the re-switching or redirection of the UE in the 4G network to the 5G network; on the other hand, for the case that the EPS Fallback procedure is detected not to exist, the UE does not perform the limiting operation, so that it can be prevented that the UE supporting the VoNR cannot be handed over again or redirected to the 5G network under the 4G network due to misjudgment, and cannot enjoy the high-quality service of the 5G network.

Fig. 3 is a flowchart of a data processing method according to another embodiment of the present invention, and as shown in fig. 3, step 220 can be implemented by step 2210.

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

In some embodiments, the 5G network may further include a network side, where the network side may include an access network and a core network, and 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 a 5G network as an example, the network side may include a 5G access network and a 5G core network, and 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 from measuring 5G network cells based on the 4G network 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 property of the UE performing the 5G measurement, the UE dropping back to the 4G network through the EPS Fallback can suspend the 5G measurement during the IMS call connection establishment, that is, suspend the UE to measure the 5G network cell based on the 4G network, so that the UE does not acquire any data about the 5G network, such as 5G cell distribution, 5G signal quality, 5G signal strength, and the like. It can be understood that, since the 5G measurement is suspended, the UE does not send the inter-system measurement report to the network side, so that the network side does not send the UE an instruction to re-switch or redirect the 4G network to the 5G network according to the measurement result.

Through the method, during the IMS call connection between the UE and another terminal, the UE is prevented from measuring the 5G network cell based on the 4G network, the UE cannot acquire any data about the 5G network, and the network side cannot receive the inter-system measurement report of the UE, so that the network side cannot send the command of re-switching or redirecting back to the 5G network to the UE, and the failure of voice call caused by the 5G network which does not support VoNR of the UE is prevented.

Fig. 4 is a flowchart of a data processing method according to another embodiment of the present invention, and as shown in fig. 4, step 220 can be implemented by step 2220.

Step 2220, the UE is restricted from sending the obtained inter-system measurement report to the network side, so as to restrict the network side from sending an instruction to the UE to re-switch or redirect the 4G network to the 5G network according to the measurement result.

According to the foregoing, after receiving the 5G inter-system measurement report sent by the UE in the 4G network, the 4G access network sends an instruction to the UE to re-switch or redirect to the 5G network, so that the UE can re-switch or redirect to the 5G network that does not support VoNR, resulting in a failure of voice call.

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, the UE may issue an interception instruction for the inter-system measurement report before sending the inter-system measurement report to the network side. For another example, the UE may clear the data of the inter-system measurement report before sending the inter-system measurement report to the network side. Thus, 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 limited from sending the instruction for re-switching or redirecting the 4G network to the 5G network to the UE.

Through the method, during the IMS call connection between the UE and the other terminal, the network side can not receive the measurement report of the different system of the UE by limiting the UE from sending the measurement report of the different system to the network side, so that the network side can not send the command of re-switching or redirecting back to the 5G network to the UE, and the failure of voice call caused by the 5G network which does not support VoNR of the UE is prevented.

It should be noted that, when the UE performs one 5G measurement and reports one inter-system measurement report, and the 5G measurement is performed in real time, during the period that the UE falls back to the 4G network through the EPS Fallback and establishes an IMS call connection with another terminal, no matter whether the UE is restricted from measuring the 5G network cell based on the 4G network or is restricted from sending the obtained inter-system measurement report to the network side, the two ways do not greatly affect the 5G real-time measurement.

Fig. 5 is a flowchart of a data processing method according to another embodiment of the present invention, and as shown in fig. 5, after step 220 is executed, step 510 may also be executed.

And 510, when the IMS call connection is successfully or unsuccessfully established, releasing the restriction of re-switching or redirecting the 4G network to the 5G network.

Taking a scenario in which a user performs a voice call as an example, a successful IMS call connection establishment may be a call success, and a failed IMS call connection establishment may be a call failure, and accordingly, the IMS call connection establishment period may be before a UE call success and a UE call failure.

In some embodiments, when the IMS call connection is established successfully, the UE may release the restriction to re-handover or redirect the 4G network to the 5G network. The target of the restriction release may be the UE that has performed the restriction operation in step 220 or step 2210 or step 2220.

In some embodiments, the IMS call connection establishment success may include the UE issuing or receiving an acknowledgement message that the IMS call connection establishment was successful. Wherein the acknowledgement message may be an ACK message. For example, after the UE receives or sends an ACK message indicating that the IMS call connection establishment is successful, the UE may confirm that the current IMS call connection establishment is successful. Thereafter, 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 may terminate suspending 5G measurements so that the UE may continue to measure 5G network cells based on the 4G network. For another example, the UE may release the interception instruction of the subsequent inter-system measurement report or set no more clearing operation of the subsequent inter-system measurement report.

In some embodiments, the IMS call connection setup failure may include the UE receiving a response indicating the IMS call connection setup failure, or the UE detecting a scenario indicating the IMS call connection setup failure.

In some embodiments, the response indicating an IMS call connection setup failure may be a failure response in a particular protocol. Such as request failure response, server failure response, global error response, etc. in the protocol rfc 3261. For example, response 400: bad request, response 504: server time-out (server timeout), response 606: not acceptable, etc.

In some embodiments, the scenario of IMS call connection setup failure may be a related scenario of UE fallback to 4G network anomaly. For example, registration failure of the UE in the current 4G cell, camping failure, or poor signal quality, poor signal strength, etc. of the current 4G network may be included.

When the UE receives the response indicating the IMS call connection establishment failure, or detects a scene indicating the IMS call connection establishment failure, it indicates that the UE can confirm that the current IMS call connection establishment failure. Thereafter, similar to the IMS call connection setup being successful, 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 may terminate suspending 5G measurements so that the UE may continue to measure 5G network cells based on the 4G network. For another example, the UE may release the interception instruction of the subsequent inter-system measurement report or set no more clearing operation of the subsequent inter-system measurement report.

Through the mode, the UE can timely and accurately remove the limitation of re-switching or redirecting the 4G network to the 5G network when the IMS call connection is successfully established or fails, so that the UE can continuously carry out real-time 5G measurement when the UE is not in the period of establishing the IMS call connection, and the construction and the perfection of the 5G are not influenced. Moreover, the data processing method of the invention can be applied to any one of two terminals establishing IMS call, does not involve complex communication among a plurality of terminals or a plurality of modules, and enables UE to conveniently and efficiently execute the data processing method.
