When a mobile terminal is in an area covered by 5G SA cell signals, the time for the mobile terminal to register to a 5G SA cell is relatively long, resulting in the problem that existing mobile terminals cannot use services such as incoming and outgoing calls, sending and receiving text messages and multimedia messages, and network services for a long time.

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0027] Generally, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0028] Hereinafter, the terms "including", "having" and their cognates that can be used in various embodiments of the present application are only intended to represent specific features, numbers, steps, operations, elements, components or combinations of the foregoing items, and should not be construed as first excluding the existence of one or more other features, numbers, steps, operations, elements, components or combinations of the foregoing items or increasing the possibility of one or more features, numbers, steps, operations, elements, components or combinations of the foregoing items.

[0029] In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0030] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of this application pertain. The terms (such as those defined in a commonly used dictionary) will be interpreted as having the same meaning as their contextual meaning in the relevant technical field and will not be interpreted as having an idealized or overly formal meaning unless clearly defined in various embodiments of this application.

[0031] See Figure 1 , Figure 1 the information interaction schematic diagram of the existing mobile communication network registration process. This architecture diagram is constructed according to the 3GPP TS24.501 protocol. Figure 1 The shown architecture diagram includes a mobile terminal, a network cell of the 5th generation mobile networks (5G) stand-alone networking, and a Long Term Evolution (LTE) network cell. Under this architecture, the mobile terminal sends a RegistrationRequest message to the 5G stand-alone networking network cell. In the case of an abnormal release of the 5G stand-alone networking RRC connection or the expiration of the T3510 timer, it is necessary to wait for the T3511 timer to count for 10 seconds before sending a registration request message to the currently registered network cell of the 5G stand-alone networking again.

[0032] According to the 3GPP TS24.501 protocol, it is necessary to send 5 registration request messages to the current network cell of the 5G stand-alone networking. After sending 5 registration request messages to the 5G stand-alone networking network cell, if the network registration still fails, the timer T3502 is started. During the timing process of the timer T3502, the network cell of the 5G stand-alone networking is disabled, and an Attach Request message or a Tracking Area Update Request message is sent to the LTE network cell. The 5G stand-alone networking capability information is removed from the Tracking Area Update Request message. The mobile terminal receives an Attach Accept message or a Tracking Area Update Accept message from the LTE network cell. Under this architecture, starting the timer T3502 requires at least 40 seconds and at most 100 seconds, consuming a relatively long time.

[0033] Embodiment 1

[0034] See Figure 2 , Figure 2 This is the information interaction schematic diagram of the mobile communication network registration provided by this application. Figure 2The architecture diagram shown includes a mobile terminal, the current network cell of the 5G standalone network to which the mobile terminal performs network registration, other network cells of the 5G standalone network, and an LTE network cell. In this architecture, the LTE network cell can be replaced by a network cell corresponding to any one of the network systems of Wimax, TD-SCDMA, WCDMA, CDMA2000, GSM, and CDMA.

[0035] Based on this architecture, the mobile communication network registration method proposed in this application can be implemented. Refer to Figure 3 , the mobile communication network registration method provided in this application mainly includes the following steps:

[0036] Step S101, during the process of registering to the current network cell of the first network system, if it is detected that a predetermined timer starts, determine that the current network cell of the first network system is abnormal.

[0037] In this embodiment, the predetermined timer is used to determine whether the current network cell is abnormal. In Figure 2 the architecture diagram shown, the predetermined timer is the T3511 timer, the timer value of the T3511 timer is 10 seconds, and the reasons for starting the T3511 timer include: Radio Resource Control (RRC) connection failure, timer T3510 timeout, etc. The T3511 timer stops timing when transmitting a registration request. After the T3511 timer times out, if there is still a need to send a registration request, the registration request will be resent.

[0038] The timer value of the T3510 timer is 15 seconds, and the reason for starting the T3510 timer is to transmit a registration request message. The T3510 timer stops timing when transmitting a registration acceptance message or a registration rejection message. When the T3510 timer times out, the T3511 timer or the T3502 timer is started according to the regulations.

[0039] The timer value of the T3502 timer is 12 minutes. The reason for starting the T3502 timer is that after sending 5 registration request messages to the 5G standalone network cell and still failing to register to the network. The T3502 timer stops timing when transmitting a registration request message. After the T3502 timer times out, if there is still a need to register to the network, the registration process will be started.

[0040] In this way, it is possible to quickly determine whether the current network cell is abnormal by detecting whether the predetermined timer starts, reducing the time for determining that the currently registered network cell is abnormal.

[0041] Optionally, after step S101, the method shown may further include:

[0042] Disable the current network cell of the first network system.

[0043] Please refer to again Figure 2 , Figure 2 In Figure 2 , the first network mode is a 5G network with independent networking. When the current network cell of the 5G network with independent networking is abnormal, the current cell of the 5G network with independent networking is disabled.

[0044] In this way, the abnormal network cell can be disabled, avoiding re-searching or registering for the abnormal network cell, reducing the search and network registration time, and improving the success rate of registering for the network.

[0045] Step S102: Search for candidate network cells.

[0046] In this embodiment, the candidate network cells include other network cells outside the current network cell of the first network mode, and / or network cells of the second network mode.

[0047] Optionally, the first network mode is a 5G network with independent networking, and the second network mode is any one of LTE, Wimax, TD-SCDMA, WCDMA, CDMA2000, GSM, and CDMA.

[0048] Please refer to again Figure 2 , in Figure 2 Under the network architecture shown in Figure 2 , the candidate network cells include other network cells of the 5G network with independent networking, and / or LTE network cells. The number of other network cells of the 5G network with independent networking and LTE network cells is determined by the actual search result, which may be 1, 2, or more, or may be 0, and is not limited herein.

[0049] Optionally, please refer to Figure 4 , step S102 may include the following steps:

[0050] Step S1021: Determine the first frequency band corresponding to the first network mode;

[0051] Step S1022: According to the first frequency band, search for candidate network cells outside the current network cell of the first network mode.

[0052] In this embodiment, each network mode has a corresponding frequency band. For example, the frequency bands of the 5G network with independent networking mainly include: 450 MHz - 6000 MHz, 24250 MHz - 52600 MHz, etc. The frequency bands of the LTE network include: 1880 - 1900 MHz, 2320 - 2370 MHz, 2575 - 2635 MHz, 2300 - 2320 MHz, 2555 - 2375 MHz, 2370 - 2390 MHz, 2635 - 2655 MHz, etc.

[0053] Please refer to again Figure 2 , in Figure 2 Under the network architecture shown, the first network mode is an independent 5G network. By searching the frequency bands 450 MHz - 6000 MHz and 24250 MHz - 52600 MHz, other network cells of the independent 5G network can be searched for.

[0054] In this way, the corresponding candidate network cells of the corresponding network mode can be quickly searched according to the corresponding frequency bands, improving the efficiency of searching for candidate network cells.

[0055] Step S103: Select a target network cell from the candidate network cells for registration according to a predetermined priority.

[0056] In this embodiment, if the candidate network cell is a network cell other than the current network cell of the first network mode, a registration request message can be sent to a network cell other than the current network cell of the first network mode, and a registration request message can be received from a network cell other than the current network cell of the first network mode to complete network registration.

[0057] If the candidate network cell is a network cell of the second network mode, a registration request message or a tracking area update message can be sent to the network cell of the second network mode, and a registration request message or a tracking area update acceptance message can be received from the network cell of the second network mode to complete network registration.

[0058] Optionally, step S103 may include the following steps: If the number of candidate network cells of the first network mode is greater than or equal to 2, according to the signal strength of the candidate network cells of the first network mode, select the target network cell with the strongest signal strength from the candidate network cells of the first network mode for registration.

[0059] It can be understood that the stronger the signal strength of a network cell, the better the service quality of the network cell. Selecting the network cell with the strongest signal strength for registration can improve the success rate of network registration.

[0060] For example, in Figure 2 Under the architecture shown, if the number of other network cells of the independent 5G network is greater than or equal to 2, select the target network cell with the strongest signal strength from the other network cells of the independent 5G network for registration.

[0061] In this way, registration can be performed on the target network cell with the strongest signal strength among the candidate network cells of the first network mode, improving the success rate of network registration.

[0062] Optionally, please refer to Figure 5, according to the signal strength of the candidate network cells of the first network mode, select the target network cell with the strongest signal strength from the candidate network cells of the first network mode for registration, including the following steps:

[0063] Step S1031, sort the candidate network cells of the first network mode in descending order of network signal strength to obtain the first candidate network cell sequence;

[0064] Step S1032, if the registration to the target network cell fails when the i-th candidate network cell in the first candidate network cell sequence is determined as the target network cell, determine the (i + 1)-th candidate network cell in the first candidate network cell sequence as the target network cell for registration.

[0065] In this embodiment, i is greater than or equal to 1 and less than N, where N is the number of candidate network cells of the first network mode.

[0066] It should be supplementary explained that the first network mode is the network mode with the highest priority among the pre-acquired network modes, and the second network mode is any network mode other than the network mode with the highest priority among the pre-acquired network modes.

[0067] Optionally, the pre-acquired network modes include the 5G network with independent networking, LTE, Wimax, TD-SCDMA, WCDMA, CDMA2000, GSM, and CDMA. The first network mode is the 5G network with independent networking, and the second network mode is any one of LTE, Wimax, TD-SCDMA, WCDMA, CDMA2000, GSM, and CDMA.

[0068] In this embodiment, by sorting the candidate network cells of the first network mode in descending order of signal strength and attempting to register to the network cell with the strongest signal strength in turn, it is possible to preferentially register to the network cell with the strongest signal strength of the first network mode to ensure the network service quality.

[0069] In another specific implementation, refer to Figure 6 , step S102 may include the following steps:

[0070] Step S1023, if the registration to the target network cell with the strongest signal strength among the candidate network cells of the first network mode fails, determine the second frequency band corresponding to the second network mode;

[0071] Step S1024, search for candidate network cells of the second network mode according to the second frequency band.

[0072] In this embodiment, the second network mode is any one of LTE, Wimax, TD-SCDMA, WCDMA, CDMA2000, GSM, and CDMA. For example, the frequency bands of the LTE network include: 1880 - 1900 MHz, 2320 - 2370 MHz, 2575 - 2635 MHz, 2300 - 2320 MHz, 2555 - 2375 MHz, 2370 - 2390 MHz, 2635 - 2655 MHz, etc.

[0073] It should be supplementary noted that Figure 2 In the shown architecture, the second network mode is LTE. By searching for the frequency bands 1880 - 1900 MHz, 2320 - 2370 MHz, 2575 - 2635 MHz, 2300 - 2320 MHz, 2555 - 2375 MHz, 2370 - 2390 MHz, 2635 - 2655 MHz, an LTE network cell can be searched.

[0074] Optionally, step S103 may further include:

[0075] If the number of candidate network cells of the second network mode is greater than or equal to 2, determine the target network cell with the strongest signal strength from the candidate network cells of the second network mode according to the signal strength of the candidate network cells of the second network mode, and perform registration.

[0076] For example, in Figure 2 the shown architecture, the second network mode is LTE. If the number of candidate network cells for LTE is greater than or equal to 2, select the target network cell with the strongest signal strength from the candidate network cells for LTE and perform registration.

[0077] In this way, the target network cell with the strongest signal strength among the candidate network cells of the second network mode can be registered, improving the success rate of network registration.

[0078] Optionally, please refer to Figure 7 , determining the target network cell with the strongest signal strength from the candidate network cells of the second network mode according to the signal strength of the candidate network cells of the second network mode includes the following steps:

[0079] Step S1033, sort the candidate network cells of the second network mode in descending order of network signal strength to obtain a second candidate network cell sequence;

[0080] Step S1034, if the j-th candidate network cell in the second candidate network cell sequence is determined as the target network cell and the registration to the target network cell fails, determine the (j + 1)-th candidate network cell in the second candidate network cell sequence as the target network cell for registration.

[0081] In this embodiment, j is greater than or equal to 1 and less than M, where M is the number of candidate network cells of the second network mode. By sorting the candidate network cells of the second network mode according to the signal strength from strong to weak and attempting to register to the network cell with the strongest signal strength in turn, it is possible to ensure that the optimal network cell is selected from the candidate network cells of the second network mode for registration and ensure the network service quality.

[0082] The mobile communication network registration method provided by this application can quickly determine whether the current network cell of the first network mode is abnormal by whether a predetermined timer is started; if the current network cell of the first network mode is abnormal, search for other network cells outside the current network cell of the first network mode and / or network cells of the second network mode as candidate network cells, and select a target network cell from the candidate network cells for registration according to a predetermined priority. In this way, the time for determining the abnormality of the current network cell is reduced, the target network cell is quickly selected from the candidate cells for registration, the mobile communication network registration time is greatly reduced, the time for the mobile terminal to be unable to use services such as incoming and outgoing calls, sending and receiving text messages and multimedia messages, and network services is effectively reduced, and the mobile communication service quality is improved.
