The technical solutions provided by the embodiments of the present application can be applied to the above communication system. The network architecture and service scenarios described in the embodiments of the present application are for the purpose of illustrating the technical solutions of the embodiments of the present application more clearly, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. The evolution of the architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

Specifically, in the technical solutions provided in the embodiments of the present application, the first core network device sends a query request to the shared device; after that, the first core network device receives the feedback message sent by the shared device, and determines the second core network according to the feedback message The device sends the service data to be transmitted to the second core network device, so that the second core network device sends the service data to the terminal.

However, if the first core network device wants to determine the second core network device, it needs to perform network registration on the terminal number in the shared device in advance, so that the first core network can obtain the information of the terminal number, and then determine the first core network according to the information of the terminal number. Two core network equipment. Therefore, before the detailed introduction of the network sharing method according to the embodiment of the present application, the network registration method of the terminal number provided by the present application is introduced first.

As shown in FIG. 2 , a method for registering a terminal number provided in an embodiment of the present application includes the following steps:

S101. A first core network device receives a first network registration message sent by a terminal.

The first core network device provides services for the first number. The first network registration message is used for network registration of the first number.

Optionally, before the first core network device receives the first network registration message sent by the terminal, the terminal checks the information of the SIM card and uSIM card inserted into the terminal to determine the operator network that the terminal can use. Exemplarily, the terminal can determine the operator to which the SIM card belongs according to the PLMN network number of the SIM card, and then determine that the terminal can use the operator's network.

Afterwards, the terminal may determine the first number according to the order in which the user inserts the SIM card, user settings, and the priority of using the SIM card, which is not limited in this embodiment of the present application. For example, if the first SIM card inserted into the terminal belongs to operator A and the number is 186xxxxxxxx, the first number is 186xxxxxxxx.

Optionally, before the first core network device receives the first network registration message sent by the terminal, the terminal may generate other numbers than the first number in the at least one number by using a virtual number, an eSIM card, or the like. There are numbers other than the first number that are different from those of the operator to which the first number belongs.

It can be understood that when the terminal uses the carrier network to which the first number belongs, if the first core network device cannot send the service data to be transmitted to the terminal, the first core network can send the service data to the terminal to which other numbers other than the first number belong. The core network equipment of the operator sends the service data to be transmitted, so that the terminal can normally receive the service data to be transmitted.

In a possible design, the first network registration message includes: a network shared identifier and information about each number in the at least one number. The network sharing identifier is used to instruct to send the second network registration message to the sharing device. The second network registration message is used for network registration of every other number except the first number.

Wherein, the information of each number includes the terminal (for example, mobile phone) number, the International Mobile Subscriber Identity IMSI, and the like. This embodiment of the present application does not limit this.

In this embodiment of the present application, the value of the network shared identifier may be a first preset value or a second preset value. If the value of the network shared identifier is the first preset value, the at least one number in the first network registration message includes the first number and other numbers except the first number. If the value of the network shared identifier is the second preset value, the at least one number in the first network registration message does not include information of other numbers except the first number.

Optionally, after the first core network device receives the first network registration message sent by the terminal, the first core network device performs network registration on the first number.

S102. The first core network device sends a second network registration message to the shared device.

Wherein, the second network registration message includes: a network shared identifier and information of each number in the at least one number. Exemplarily, the second network registration message includes the following parameters:

cucc=186xxxxxxxx, SUCI=xxxx, Combine Req: 1, cmcc=139ccccdddd, SUCI=xxxx, ctcc=189eeeeffff, SUCI=xxxx.

Among them, cucc is the abbreviation of the name of operator A, cmcc is the abbreviation of the name of operator B, ctcc is the abbreviation of the name of operator C, and SUCI is the symbol corresponding to each operator's number.

Optionally, after the first core network sends the second network registration message to the sharing device, the sharing device establishes the first number and other numbers except the first number according to the first number and other numbers except the first number. Correspondence between. Exemplarily, the first number is 186xxxxxxxx, and other numbers other than the first number include 139ccccdddd and 189eeeeffff. Table 1 shows the correspondence between the first number and other numbers except the first number.

Table 1

In a possible implementation manner, the first core network device detects that the first network registration message includes a network sharing identifier, and sends a second network registration message to the sharing device.

Optionally, after the sharing device receives the second network registration message, the sharing device uses each number other than the first number to send the third Network registration message. The third network registration message is used to perform network registration for each number other than the first number in the core network equipment of the operator. In this way, the second core network device can provide services to its corresponding number.

Wherein, the third network registration message includes information of any number in other numbers except the first number.

Based on the technical solution shown in FIG. 2 , the terminal can register every other number except the first number with the shared device when performing network registration for the first number, so that the shared device records the correspondence between the first number and other numbers. If the operator network corresponding to the first number is unavailable, the terminal can search for other numbers through the first number, and use the operator network corresponding to the other number to receive service data to be transmitted.

As shown in FIG. 3 , a method for sharing a network provided by an embodiment of the present application includes the following steps.

S201. In the case that the first core network device determines that the service data to be transmitted cannot be sent to the terminal, the first core network device sends a query request to the shared device.

In the embodiment of the present application, when the terminal is out of service, the network is abnormal, etc., the heartbeat detection between the base station and the terminal times out, the operator network considers that the user is offline, and the first core network device cannot send the service data to be transmitted to the terminal. This embodiment of the present application does not limit this.

The query request is used for requesting to query the information of at least one number registered by the terminal in the shared device. The query request includes: the network shared identifier and/or the information of the first number. At least one number belongs to a different operator. The first core network device provides services for the first number of the at least one number.

In a possible implementation manner, in a 5G network, the UPF network element sends a DownlinkData message to the SMF network element, the SMF sends a Data Notification message to the AMF network element, and the AMF network element sends a query message to the shared device.

It should be noted that the first core network device may be an AMF network element, or may be any network element that has an interface with the shared device, which is not limited in this embodiment of the present application.

It can be understood that, since the numbers of different operators of the terminal are registered in the shared device, the first core network device can determine the information of the numbers registered by the terminal on the side of other operators through the shared device. For a specific description of the network registration of the terminal number in the shared device, reference may be made to steps S101-S102, which will not be repeated in this embodiment of the present application.

Optionally, after the first core network device sends the query request to the sharing device, the sharing device receives the query request, and determines the feedback message according to the query request.

Exemplarily, the first core network device sends the network sharing identifier (Combine Req) and the information of the first number (cucc=186xxxxxxxx, SUCI=xxxx) to the sharing device, and the sharing device determines according to the correspondence between the first number and other numbers. The value of the network share identifier is the first preset value (eg "1"), and other numbers of information (cmcc=139ccccdddd, SUCI=xxxx, ctcc=189eeeeffff, SUCI=xxxx).

S202. The first core network device receives the feedback message sent by the sharing device.

Wherein, the feedback message includes information of each other number in the at least one number except the first number.

Optionally, the feedback message further includes the value of the network share identifier. In this way, the first core network device can determine, according to the value of the network shared identifier, whether there are other numbers other than the first number in the shared device.

Exemplarily, the feedback message is Combine Req: 1, cmcc=139ccccdddd, SUCI=xxxx, ctcc=189eeeeffff, SUCI=xxxx.

S203. The first core network device determines the second core network device according to the feedback message.

In a possible implementation manner, the first core network device detects the value of the network shared identifier; if the value of the network shared identifier is the first preset value, the first core network device determines the second core network according to the information of the second number. equipment.

Wherein, the second number is any number in the at least one number except the first number. The second core network device provides services for the second number, and the first number is different from the second number.

S204: The first core network device sends the service data to be transmitted to the second core network device.

Optionally, after the first core network device sends the service data to be transmitted to the second core network device, the second core network device sends the service data to the terminal.

Based on the above technical solutions, if the service data to be transmitted cannot be sent to the terminal (for example, when the terminal uses the network of operator A, the terminal has no signal), the core network device (first core network device) of operator A sends the data to the shared device. The query request enables the first core network device to receive information about each other number except the first number fed back by the sharing device. In this way, the first core network device can determine the number information of the terminal registered with other operators. After that, the first core network device determines the core network device (second core network device) of operator B that provides services for the second number (different from the first number, the second number belongs to operator B), and will transmit the The service data is sent to the second core network device, so that the second core network device sends the service data to be transmitted to the terminal through the base station of the operator B. Therefore, when the terminal cannot receive the service data to be transmitted sent by the first core network device, the terminal can receive the service data to be transmitted through the second core network device, which improves the stability of service data transmission and enhances the user experience.

Optionally, the technical solution of the present application can be applied not only to the above scenario where the operator cannot send the service data to be transmitted to the terminal (that is, the transmission of downlink data cannot be completed), but also can be applied to the terminal unable to send the service data to be transmitted to the operator. (that is, the transmission of uplink data cannot be completed).

Specifically, if the terminal cannot send the service data to be transmitted to the first core network device, the terminal can query the terminal for numbers other than one number and the signal strength of the operator to which the other numbers belong. Afterwards, according to the signal strength of the operator to which the other numbers belong and the preset rules, it is determined that the core network device of the operator to which one of the other numbers belongs is the target core network device. From the above, the terminal can send the service data to be transmitted to the target core network device, so as to avoid the failure of uplink data transmission.

Wherein, the preset rule is set by the developer. Exemplarily, the preset rule may be to determine that among the signal strengths of operators to which other numbers belong, the core network device of the operator with the highest signal strength is the target core network device. This embodiment of the present application does not limit this.
