Description

Network registration method, network registration device, storage medium and terminal equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a network registration method, a network registration device, a computer readable storage medium, and a terminal device.

Background

Currently, some network operators will offer packet-only, voice-free networks, such as EPS (Evolved Packet System ) with only 4G, LTE (Long Term Evolution, long term evolution) networks without 2G/3G and IMS (Internet-Protocol Multimedia Subsystem, network protocol multimedia subsystem) services. Accordingly, these operators issue SIM cards (Subscriber Identification Module, subscriber identity module) for subscription data services only, non-subscription voice services, which are commonly referred to as pure data cards or pure traffic cards, i.e. SIM cards that can only be connected to the internet and cannot make calls.

In the related art, if the pure data card is inserted into the mobile phone, registration is initiated to the operator network, and a message of voice service registration failure is returned because the operator network has no voice service. According to 3GPP (3 rd Generation Partnership Project, third Generation partnership project, generally referred to as Global communication technology organization) protocol TS23.221, voice-Centric (Voice center) terminals need to ensure that Voice services are available, and when Voice services fail registration, the terminals search for a 2G/3G network and register, resulting in slower data services than expected; even if the operator does not provide the 2G/3G network service, the terminal may show no service.

In the related art, the mobile phone is generally default to be voice-centered, and when a pure data card is inserted and registered with the LTE network of the operator, the mobile phone automatically disables the E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, evolved UMTS terrestrial radio access network, UMTS is called Universal Mobile Telecommunications System, which refers to a universal mobile telecommunications system) because the voice service cannot be acquired, which indicates that the LTE service cannot be acquired any more in a period of time. Next, the handset will attempt to search for networks on other systems, such as 2G/3G networks. For some operators without 2G/3G network coverage, the mobile phone fails to search for the 2G/3G network. And then may attempt to search for other non-subscribed networks.

Fig. 2 shows an exemplary flow of a network registration method, which may include the following steps S210 to S230:

step S210, under the voice-centered setting, initiating a joint attachment request of a packet service and a voice service to a target system network;

step S220, when receiving the message that the packet service registration is successful and the voice service registration is failed returned by the target standard network, determining that the registration to the target standard network is failed, and searching for a non-target standard network;

in step S230, when searching for the non-target system network fails, the data is set as a center and re-registered to the target system network.

By the method, the problem that the pure data card cannot normally register the network in the related technology is solved, so that the UE inserted with the pure data card is normally registered in the target system network to use the data service of the network, the situation that the UE is not served when an operator does not provide a non-target system network is avoided, and the user is ensured to normally surf the network through mobile data.

Each step in fig. 2 is described in detail below.

In step S210, a joint attach request of a packet service and a voice service is initiated to a target standard network under a voice-centric setting.

Voice Centric (Voice Centric) and Data Centric (Data Centric) are one arrangement for a UE to connect to an LTE network that indicates whether the UE is Voice-based or Data-based when registering with the network. Typically, this setting on the UE defaults to voice-centric.

In the present exemplary embodiment, the target system may be a network system including both a data service and a voice service, such as LTE, NR, and the like. For such networks, the UE typically needs to initiate a joint attach request for packet services (i.e., data services) and voice services at registration. Taking an LTE network as an example, when a mobile phone registers with the LTE network, a Combined EPS/IMSI attach request, that is, a Combined EPS and IMSI (International Mobile Subscriber Identity ) attach request is initiated, where the EPS attach request is used to register data services in the LTE network, and the IMSI is used to register voice services in the LTE network.

It should be noted that, step S210 is actually an initial flow of registration of the UE, and generally, when the UE is turned on or switches from the flight mode to the mobile mode, the UE is triggered to register with the network, or when the UE enters another area to perform TAU (Tracking Area Update ), the UE is also triggered to register with the network, which is not limited to the specific scenario of network registration in the present disclosure.

With continued reference to fig. 2, in step S220, when a message that the packet service registration is successful and the voice service registration is failed, which is returned by the target standard network, is received, it is determined that the registration to the target standard network is failed, and a non-target standard network is searched.

Since the UE uses a pure data card, the corresponding operator network is a network that does not provide voice services, the request for voice services in the joint attach request will be denied, i.e. the voice service registration fails, while the packet service can be registered successfully. Taking LTE network as an example, the message returned to the UE may include: EPS registration success, IMSI registration failure, and indication information that the LTE network does not support IMS (e.g., attach accept message does not indicate IMS voive over PS session Supported). The IMSI registration failure means that the LTE network does not support CSFB (Circuit Switched Fallback ), i.e. cannot provide voice service through the CS domain; meanwhile, if the LTE network does not support IMS, voLTE (Voice over Long Term Evolution, long term evolution voice bearer) service cannot be provided based on IMS. While CSFB and IMS are two main ways for an LTE network to provide voice services, that is, the LTE network cannot provide voice services.

Under the voice-centric setting, the voice service registration fails, meaning that the UE fails to register with the target-style network. At this time, the system can be switched to other systems (i.e. non-target systems) and search for related networks, for example, networks of GSM, EDGE, etc.

In an alternative embodiment, when the target standard network is an LTE network and a message that packet service registration is successful and voice service registration fails is returned, the UE may record the LTE network as an EPS only network (a network supporting only an evolved packet system), for example, may record a PLMN (Public Land Mobile Network ) of the LTE network and be labeled as EPS only. The EPS only network indicates that the LTE network, unlike the general LTE network, can only provide EPS services and cannot provide voice services. By recording the EPS only network, the LTE network can be distinguished, so that a general LTE network can be preferentially connected when connected.

In an alternative embodiment, the record information of the EPS only network may be updated when the next registration is completed. For example, when the network has increased voice service the next time it registers with the network, the UE's packet service and voice service joint attach request are both successfully answered, indicating that the services that the network can provide are no longer limited to EPS, so the EPS only flag can be cleared.

In an alternative embodiment, when the UE receives a message that the packet service registration is successful and the voice service registration is failed returned by the target system network, the target system may be disabled. For example, when the target standard network is judged to be the EPS only network, the (disable) E-UTRAN may be disabled, for example, for a period of time set for 12 minutes or the like, during which the UE cannot acquire LTE service any more, so that the UE can only switch to another standard to search for a network, for example, search for GERAN (GSM EDGE Radio Access Network, GSM/EDGE radio communication network), UTRAN (UMTS Terrestrial Radio Access Network, universal terrestrial radio access network). When the target system is disabled, the target system can be added into a forbidden list of the network and the system, and the forbidden list can be positioned in a protocol stack.

With continued reference to fig. 2, in step S230, when searching for the non-target-format network fails, data is set as a center, and re-registration to the target-format network is performed.

Generally, the operator does not provide a non-target standard network, which may cause searching failure, meaning that the UE fails to register with both the target standard network and the non-target standard network. In general, the UE is in an out-of-service state, and cannot use mobile data to access the internet. In the present exemplary embodiment, the network service is not found at all for the UE, and at least the packet service of the target-system network is available (registration success in step S220). Therefore, the voice-centered setting can be modified to be data-centered, and then the registration is performed again to the target standard network, and the registration can be successful because the packet service is available.

In an alternative embodiment, in order to make the UE record the information that the packet service of the target system network is available, the target system network may be recorded as the EPS only network, which indicates that the EPS service is available. Accordingly, in step S230, it may be determined whether there is a packet service available by querying relevant information of the EPS only network. Specifically, referring to fig. 3, step S230 may include the following steps S310 and S320:

step S310, when searching non-LTE network fails, searching whether the record information of EPS only network exists;

step S320, when the record information of the EPS only network is found, setting the data as a center and registering to the found EPS only network.

If, when determining that the LTE network is an EPS only network, relevant information is recorded, for example, the LTE network is recorded on a list of EPS only networks, then the list is searched at this time, so that the recorded information of the EPS only networks can be obtained, which indicates that the EPS only networks provide available packet services. Therefore, the method can be set to take data as a center and then initiate registration to the found EPS only network, so that the success of registration is ensured.

It should be noted that, if the target format is disabled in step S220, the disabling of the target format needs to be cleared in step S230, and then re-registration is performed. Thus, the re-registration process can be immediately performed without waiting for a disable time set for 12 minutes or the like.

In an alternative embodiment, the forbidden list of networks and modes can be reset by restarting the protocol stack, so that all networks and modes recorded on the forbidden list, including the target mode, are cleared. The mode of restarting the protocol stack is simple and convenient to implement.

In an alternative embodiment, referring to fig. 4, the UE may be re-registered to the target mesh network by the following steps S410 and S420:

step S410, re-initiating a joint attachment request to the target standard network;

step S420, when the message of successful packet service registration and voice service registration failure returned by the target standard network is received again, registering to the target standard network.

Wherein the re-initiated joint attach request may be the same as the joint attach request in step S210, including attach requests for packet services and voice services. The target standard network generally returns the same result as step S220, i.e., a message that the packet service registration was successful and the voice service registration was failed. At this time, since the UE is modified to be data-centric, according to the 3GPP protocol TS23.221, when registering with the LTE network, even if the LTE network does not support CSFB and IMS, the packet service of the LTE network can be continuously registered and used.

Fig. 5 shows another schematic flow of the network registration method in the present exemplary embodiment, taking the case of registering an LTE network, the flow includes:

in step S501, when the UE registers with the network, an EPS/IMSI attach request is initiated first.

Step S502, the UE receives the message returned by the LTE network, judges whether the LTE network is an EPS only network, and if not, executes step S503; if yes, go to step S504.

Step S503, register to the LTE network, and the flow ends.

Step S504, checking whether the voice is set as the center currently, if so, executing step S505; if not, step S514 is performed.

In step S505, the PLMN of the EPS only network is recorded.

In step S506, the E-UTRAN is disabled to disable the LTE function.

And S507, switching to searching the related network on the 2G/3G system.

Step S508, confirm whether to search 2G/3G network fails, if not, carry out step S509; if yes, go to step S510.

In step S509, when a 2G/3G network is searched, the network is registered, and the flow ends.

Step S510, searching the record information of the EPS only network, if not, executing step S511; if so, step S512 is performed.

In step S511, the no-service result can be output without performing the subsequent processing, and the flow ends.

In step S512, data is set as the center.

Step S513, initiating registration to the found EPS only network.

Step S514, the successful registration is determined, the data service is normally acquired, and the process is ended.

Through the flow of fig. 5, the UE can be ensured to register to the EPS only network successfully, so that the user can use the mobile data to surf the internet normally.

Exemplary embodiments of the present disclosure also provide another network registration method. Referring to fig. 6, the network registration method may include the following steps S610 to S630:

step S610, under the voice-centered setting, initiating a joint attachment request of a packet service and a voice service to a target system network;

step S620, when receiving the message of successful packet service registration and voice service registration failure returned by the target standard network, searching the target standard network in a preset list;

in step S630, when the target standard network is found in the preset list, the data is set as a center and registered to the target standard network.

The target system may be a network system including both data service and voice service, such as LTE, NR, etc., and the target system network may be an LTE network, an NR network, etc. The preset list may be a list of EPS only networks, for example, a list of PLMNs of known EPS only networks is recorded, stored in the UE, and may be kept updated.

In the flow of fig. 6, step S610 is the same as step S210, and the message received by the UE in step S620 is the same as the message in step S220, and at this time, the UE may compare the PLMN of the target standard network with the PLMN of the EPS only network in the preset list to determine whether the target standard network is in the preset list. Further, in step S630, when the target system network is found in the preset list, it is determined that the target system network is an EPS only network, packet service is provided but voice service is not provided, and the UE may modify the voice-centric setting to be data-centric, so as to successfully register into the EPS only network.

By the method shown in fig. 6, it can be ensured that the UE inserted with the pure data card successfully registers in the network providing only packet service and not providing voice service, so that the user can normally use mobile data to surf the internet. And, need not to switch to searching network on other systems, thus has reduced the time that the network registers and needs.

Claims

1. A network registration method, comprising:

under the voice-centered setting, initiating a joint attachment request of packet service and voice service to a target system network;

when receiving the message that the packet service registration is successful and the voice service registration is failed returned by the target standard network, determining that the registration to the target standard network is failed, and searching for a non-target standard network;

when searching the non-target system network fails, setting the data as a center and re-registering the data to the target system network.

2. The method of claim 1, wherein when receiving a message that the packet service registration is successful and the voice service registration is failed returned by the target-compliant network, the method further comprises:

disabling a target system;

when searching for the non-target system network fails, the method further comprises the following steps:

and clearing the forbidden target system.

3. The method of claim 2, wherein the clearing of the disabling of the target format comprises:

4. The method of claim 1, wherein the re-registering with the target-compliant network comprises:

re-initiating the joint attachment request to the target standard network;

5. The method of claim 1, wherein the target compliant network comprises a long term evolution, LTE, network.

6. The method of claim 5, wherein the message of successful registration of the packet service, failed registration of the voice service, comprises:

the evolution packet system EPS registration is successful, the international mobile subscriber identity IMSI registration fails, and the indication information that the LTE network does not support the network protocol multimedia subsystem IMS.

7. The method of claim 6, wherein upon receiving a message returned by the target-compliant network that the registration of the packet service was successful and the registration of the voice service failed, the method further comprises:

recording the LTE network as supporting only an evolved packet system EPS only network.

8. The method of claim 7, wherein the setting the data as center and re-registering to the target-based network when searching for the non-target-based network fails, comprises:

9. A network registration apparatus, comprising:

a first registration unit, configured to initiate a joint attachment request of a packet service and a voice service to a target standard network under a voice-centric setting;
