Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular to a network access mode switching method, a network access mode switching device, a computer readable storage medium and an electronic device. BACKGROUND

[0002] A user can use a terminal device to communicate with a base station, wherein the base station can be a 4G base station or a 5G base station. If the terminal device can establish a connection with the 5G base station, the terminal device can use the 5G network to realize communication. If the terminal device establishes a connection with the 4G base station, the terminal device can use the 4G network to realize communication.

[0003] However, in actual application, the 5G network itself does not support voice service (i.e., VoLTE service), and the voice service needs to be realized by falling back to the 4G network according to the Evolved Packet System Fallback (EPS Fallback) mode. Based on the fact that the terminal device accesses the 4G network, if the terminal device is in a poor signal area and cannot connect to the 4G network multiple times, a disable timer will be triggered to start timing. During the timing process, the terminal device disables the 4G network and searches for the 5G network. After the terminal device searches for and accesses the 5G network, the terminal device can perform the voice service according to the Evolved Packet System Fallback (EPS Fallback) mode.

[0004] During the process in which the terminal device disables the 4G network and does not search for the 5G network, the terminal device searches for the 2G / 3G network. If the search fails, the voice service will fail.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0061] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations can be implemented in any

[0062] Moreover, the drawings represent a simplified schematic illustration of the application and are not necessarily to scale. Identical reference numerals in different drawings denote the same or similar components. Repetitive description of like elements employed in the different drawings can be omitted for sake of brevity. Some of the block diagrams shown in the drawings are functional entities that do not necessarily have to correspond to physically or logically independent entities. These functional entities can be implemented in software, or in one or more hardware modules or integrated circuits, or in different network and / or processor apparatuses and / or microcontroller apparatuses.

[0063] Figure 1 A structural schematic diagram of a computer system of a terminal device suitable for implementing embodiments of the present application is shown.

[0064] It should be noted that, Figure 1 The computer system 100 of the terminal device shown is only an example and should not impose any limitation on the functions and scope of use of embodiments of the present application.

[0065] As Figure 1As shown, the computer system 100 includes a central processing unit (CPU) 101 which can perform various appropriate actions and processes in accordance with programs stored in a read only memory (ROM) 102 or programs loaded from a storage section 108 into a random access memory (RAM) 103. In the RAM 103, various programs and data required for the operation of the system are also stored. The CPU 101, the ROM 102, and the RAM 103 are connected to each other through a bus 104. An input / output (I / O) interface 105 is also connected to the bus 104.

[0066] Connected to the I / O interface 105 are an input section 106 including a keyboard, a mouse, etc.; an output section 107 including a display such as a cathode ray tube (CRT), a liquid crystal display (LCD), etc., and a speaker, etc.; a storage section 108 including a hard disk, etc.; and a communication section 109 including a network interface card such as a LAN card, a modem, etc. The communication section 109 performs communication processing via a network such as the Internet. A drive 110 is also connected to the I / O interface 105 as necessary. A removable recording medium 111 such as a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, etc. is attached to the drive 110 as necessary, so that a computer program read therefrom is installed into the storage section 108 as necessary.

[0067] In particular, according to embodiments of the present application, the processes described below with reference to the flowcharts can be implemented as a computer software program. For example, embodiments of the present application include a computer program product comprising a computer program carried on a computer readable medium, the computer program containing program code for executing the methods illustrated by the flowcharts. In such embodiments, the computer program can be downloaded and installed from a network via the communication section 109, and / or installed from the removable recording medium 111. When the computer program is executed by the central processing unit (CPU) 101, various functions defined in the methods and apparatuses of the present application are performed.

[0068] When network coverage or configuration is abnormal, a terminal device usually cannot normally camp on an LTE (Long Term Evolution) network. For example, under a certain LTE cell, the terminal initiates Attach camping or Tracking Area Update (TAU), and during the random access process, a certain msg message (such as msg2) cannot be received, which may affect the terminal to normally camp on the LTE network. For another example, after establishing a Radio Resource Control (RRC) connection through random access, the LTE network does not continue to initiate subsequent operations such as authentication, but directly releases the RRC connection, which may affect the terminal to normally camp on the LTE network. If the terminal repeatedly initiates Attach or TAU because of the above abnormal situations, and the number of failures reaches 5 times, the 4G access mode corresponding timer will be started under the condition of meeting the starting condition. After the 4G access mode corresponding timer is started, only the LTE network can be restored after the timer expires. Before the timer expires, the terminal device cannot perform voice services, which causes many inconveniences to users.

[0069] To solve this problem, based on the terminal device system shown in Figure 1 The embodiment of the present application discloses a network access mode switching method. As shown in Figure 2 The network access mode switching method can be applied to a terminal device, which includes steps S210-S220.

[0070] Step S210: When the 4G access mode corresponding timer is triggered, disable the 4G access mode.

[0071] Step S220: If it is detected that the preset parameter value in the terminal device meets the effective condition, disable the timer and start the 4G access mode.

[0072] It should be noted that the technical solution of the present application can be applied to various communication systems, such as Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), etc.

[0073] The above steps of the present example embodiment are described in more detail as follows.

[0074] Before step S210, the terminal device can receive a system version update request, and when the terminal device detects an acceptance operation, the terminal device can respond to the system version update request, so as to update the system version of the terminal device. The updated system version includes a configured preset parameter (EnableT3402EarlyStop). The preset parameter (EnableT3402EarlyStop) can include multiple states, and the multiple states can be represented by different preset parameter values. The present application does not limit the types of states.

[0075] Preferably, the preset parameter (EnableT3402EarlyStop) can include two states, i.e., an effective state and a disabled state. The effective state can be represented by a first value (e.g., 1), and the disabled state can be represented by a second value (e.g., 2). Based on this, the above method further includes: when it is detected that the preset parameter value is equal to the first value, it is determined that the preset parameter value satisfies the effective condition; and when it is detected that the preset parameter value is equal to the second value, it is determined that the preset parameter value does not satisfy the effective condition. It should be noted that the preset parameter value can be set by an operator.

[0076] Based on this, step S210 can be performed. In step S210, the timer corresponding to the 4G access mode can be represented as a T3402 timer, the counting manner of the T3402 timer is countdown, the T3402 timer corresponds to a preset time length (e.g., 12 min), and when the timer is triggered to be effective, the terminal device can disable the 4G access mode (S1-mode) of the terminal device. The terminal device after disabling the 4G access mode does not have 4G access capability (E-UTRA capability).

[0077] Before step S220 detects that the preset parameter value in the terminal device satisfies the effective condition, the above method further includes: querying a preset parameter (EnableT3402EarlyStop) stored in the terminal device to obtain a preset parameter value corresponding to the preset parameter (EnableT3402EarlyStop). The preset parameter (EnableT3402EarlyStop) is stored in a mobile device (Mobile Equipment, ME) or a universal subscriber identity module (USIM) of the terminal device.

[0078] Then, step S220 can be executed. In step S220, if a preset parameter value (e.g., 1 or 0) in the terminal device is detected to meet the activation condition, the activation condition can be represented by a numerical value (e.g., 1). When the preset parameter value is consistent with the numerical value in the activation condition, it can be determined that the preset parameter value meets the activation condition. When the preset parameter value meets the activation condition, the terminal device can disable the timer and start the 4G access mode. After the 4G access mode is started, the terminal device has 4G access capability (E-UTRA capability).

[0079] Furthermore, after disabling the timer, the above method also includes: when the timer is triggered again, resetting the corresponding disable duration to a preset value (e.g., 12 minutes) and timing based on the reset timer; if the preset parameter value is detected as not meeting the effective conditions, disabling the 4G access mode until the accumulated timing duration reaches the threshold. Specifically, timing based on the reset timer is implemented by counting down the preset value based on the timer.

[0080] It is evident that implementation Figure 2 The method shown can unblock the 4G access mode, allowing terminal devices to access the 4G network and avoiding voice service failures due to the inability to access any network. Furthermore, it can promptly unblock the 4G access mode based on effective preset parameter values, preventing excessive power consumption caused by frequent attempts to access the 4G network due to access failures.

[0081] exist Figure 2 On the basis of, such as Figure 3 As shown, another method for switching network access modes can be implemented, specifically including steps S310 to S380.

[0082] Step S310: When the timer corresponding to the 4G access mode is triggered, disable the 4G access mode.

[0083] Step S320: Send a first registration message to the 5G base station so that the 5G base station forwards the first registration message to the 5G mobile management network element; wherein, the first registration message is used to indicate that the terminal device does not support the 4G access mode.

[0084] Step S330: Receive a first feedback message sent by the 5G mobile management network element; wherein the first feedback message is used to indicate that voice services corresponding to the 3GPP protocol are not supported.

[0085] Step S340: Disable 5G access mode and query 2G and 3G networks.

[0086] Step S350: If the query fails, start the 5G access mode and determine the preset parameter values.

[0087] Step S360: If the preset parameter value in the terminal device is detected to meet the effective conditions, then the timer is disabled and the 4G access mode is started.

[0088] Step S370: Send a second registration message to the 5G base station so that the 5G base station forwards the second registration message to the 5G mobile management network element; wherein, the second registration message is used to indicate that the terminal device supports 4G access mode.

[0089] Step S380: Receive a second feedback message sent by the 5G mobile management network element; wherein the second feedback message is used to indicate support for voice services corresponding to the 3GPP protocol.

[0090] The steps described above in this example implementation will now be explained in more detail.

[0091] Specifically, a 5G base station (gNB) can act as a relay station to forward messages from terminal devices to the 5G mobile management network (MLM). The 5G MLM element belongs to the 5G core network. When the timer corresponding to the 4G access mode is triggered, the 4G access mode can be disabled, and registration with the 5G network can begin. The 5G MLM element can send a first feedback message to the terminal device indicating that it does not support voice services corresponding to the 3GPP protocol; that is, EPS Fallback cannot be implemented at present. Based on this, the terminal device can search for 2G and 3G networks. If no 2G or 3G network is found, the 5G access mode (N1-mode) can be restarted, and the preset parameter value can be checked to see if it is the first value (e.g., 1). If it is, the preset parameter value is deemed to meet the activation condition. This allows the timer to be disabled and the 4G access mode to be started, enabling access to the 4G network.

[0092] Furthermore, the 3GPP protocol in step S380 above is used to characterize a wireless communication industry standard. Following step S380, the process may further include: after switching from a 4G network to a 5G network, resetting the preset parameter value from a first value (e.g., 1) to a second value (e.g., 0). If the preset parameter value = 0, it indicates that the preset parameter is temporarily invalid.

[0093] It is evident that implementation Figure 3 The method shown can unblock the 4G access mode, allowing terminal devices to access the 4G network and avoiding voice service failures due to the inability to access any network. Furthermore, it can promptly unblock the 4G access mode based on effective preset parameter values, preventing excessive power consumption caused by frequent attempts to access the 4G network due to access failures.

[0094] exist Figure 3 On the basis of, such as Figure 4 As shown, parallel network access mode switching methods can be implemented. One scheme includes step S410, and the other scheme includes steps S421 to S427.

[0095] Step S410: When the timer corresponding to the 4G access mode is triggered, the terminal device (UE) disables the 4G access mode. If the preset parameter value in the terminal device is detected to meet the activation condition, the timer is disabled and the 4G access mode is started.

[0096] Step S421: When the timer corresponding to the 4G access mode is triggered, the terminal device (UE) disables the 4G access mode and sends a first registration message to the RAN network element; wherein, the first registration message is used to indicate that the terminal device does not support the 4G access mode.

[0097] Step S422: The RAN network element forwards the first registration message.

[0098] Step S423: The AMF network element sends a first feedback message to indicate that it does not support the voice service corresponding to the 3GPP protocol.

[0099] Step S424: The terminal device (UE) disables the 5G access mode and queries the 2G and 3G networks. If the query fails, the 5G access mode is enabled and the preset parameter value is determined. If the preset parameter value in the terminal device is detected to meet the effective conditions, the timer is disabled and the 4G access mode is enabled.

[0100] Step S425: The terminal device (UE) sends a second registration message to the RAN network element.

[0101] Step S426: The RAN network element forwards the second registration message.

[0102] Step S427: The AMF network element sends a second feedback message to indicate support for the voice service corresponding to the 3GPP protocol.

[0103] The steps described above in this example implementation will now be explained in more detail.

[0104] In one embodiment, for step S410, when the T3402 timer corresponding to the 4G access mode is triggered to be effective, the terminal device (User Equipment, UE) can disable S1-mode, if it is detected that "EnableT3402EarlyStop" = 1 in the terminal device, then disable the T3402 timer and start S1-mode, so that the terminal device (UE) can establish a connection with the E-UTRA (Evolved UMTS Terrestrial Radio Access Network) network element, and then based on the E-UTRA network element and the MME (Mobility Management Entity) network element to carry out the session message transmission based on the 4G network, so as to complete the voice service. Wherein, the E-UTRAN is an evolved UMTS terrestrial radio access network, that is, the mobile communication wireless network in LTE, and the MME is a key control node of the 3GPP protocol LTE access network, responsible for the positioning of the idle mode terminal device (UE), paging process, relay, and can also be represented as a 4G mobility management entity.

[0105] In another embodiment, for steps S421-S427, the terminal device (UE) can disable the S1-mode when the T3402 timer corresponding to the S1-mode is triggered to expire, and send a first registration message to the RAN network element (corresponding to the 5G base station described above) appearing as a radio access network entity, the first registration message can also be represented as a 5G MM capability information element, which contains the specific content "S1 mode not supported", so that the first registration message is used to represent that the terminal device does not support the 4G access mode. Further, the RAN network element can forward the first registration message to the AMF network element for implementing the mobility management function after receiving the first registration message. The AMF network element can generate a corresponding first feedback message and feed back to the terminal device (UE) after receiving the first registration message, and the first feedback message can contain specific characters representing that the voice service based on the 3GPP protocol is not supported. Based on this, the terminal device (UE) can disable the 5G access mode (N1-mode), and query the 2G network and the 3G network, if the query fails, it means that there is no network element related to the 2G network and the 3G network set up by the operator nearby, then the terminal device (UE) can restart the N1-mode and determine the preset parameter value, if the preset parameter value is 1, disable the T3402 timer and start the S1-mode. Further, the terminal device (UE) can send a second registration message to the RAN network element again, the second registration message can also be represented as a 5G MM capability information element, which contains the specific content "S1 mode supported", so that the second registration message is used to represent that the terminal device supports the 4G access mode. The RAN network element can forward the second registration message to the AMF network element after receiving the second registration message, and the AMF network element can generate a corresponding second feedback message and feed back to the terminal device (UE) after receiving the second registration message. Based on this, the terminal device (UE) can establish a connection with the E-UTRA (Evolved UMTS Terrestrial Radio Access Network) network element, and then perform session message transmission based on the 4G network based on the E-UTRA network element and the MME (Mobility Management Entity) network element, thereby completing the voice service.

[0106] It should be noted that in Figure 4 , the RAN network element and the AMF network element belong to the 5G network element, and the E-UTRA network element and the MME network element belong to the 4G network element.

[0107] It can be seen that the implementation Figure 4The method shown can unblock the 4G access mode, allowing terminal devices to access the 4G network and avoiding voice service failures due to the inability to access any network. Furthermore, it can promptly unblock the 4G access mode based on effective preset parameter values, preventing excessive power consumption caused by frequent attempts to access the 4G network due to access failures.

[0108] like Figure 5 As shown, Figure 5 What is achieved is with Figure 2 A corresponding network access mode switching device is provided. This network access mode switching device 500 includes a disabling unit 501 and a enabling unit 502.

[0109] The disabling unit 501 is used to disable the 4G access mode when the timer corresponding to the 4G access mode is triggered.

[0110] The disabling unit 501 is also used to disable the timer when it is detected that the preset parameter value in the terminal device meets the effective conditions;

[0111] The startup unit 502 is used to start the 4G access mode.
