Currently, the operator's name can be stored in the Subscriber Identity Module (SIM) or non-volatile memory (NV), or can be transmitted over the air interface. When operator names exist in multiple places at the same time, they are prioritized according to the rules stipulated in the agreement.

Wherein, a CAG human-readable network name (human-readable network name, HRNN) is a human-readable network name corresponding to each CAG identifier (Identifier), which may be referred to as a CAG name for short.

The CAG HRNN may or may not be broadcast in the system information of the cell. CAG HRNN is used to display to the user (User) when the user manually selects the CAG. In the current technology, when the CAG HRNN is not sent over the air interface, the human-readable name cannot be displayed to the user, which will make it difficult for the user to perform manual CAG selection.

An embodiment of the present invention provides a method for processing CAG information. The method for processing CAG information is applied to a user equipment, as shown in FIG. 6 , including:

Step S1: The user equipment presents the CAG information corresponding to the CAG ID to the user according to preset priority rules, the CAG information includes at least one of the following: CAG name HRNN and CAG icon information, and the CAG information includes the first CAG information and/or second CAG information, the first CAG information is the CAG information in the received air interface message, and the second CAG information is the local CAG information of the user equipment.

In this embodiment, the user equipment presents the CAG information corresponding to the CAG ID to the user according to the preset priority rules, and the CAG information includes the CAG information in the air interface message and the local CAG information of the user equipment, so that when the air interface message does not carry the CAG information , and may also use the local CAG information of the user equipment to display to the user, so that the user can select a target CAG according to the CAG information.

In this embodiment, the preset priority rules may include any of the following:

The priority of the first CAG information is higher than the priority of the second CAG information;

The priority of the second CAG information is higher than the priority of the first CAG information;

If the user equipment is in a roaming area, the priority of the first CAG information is higher than that of the second CAG information, and if the user equipment is in a non-roaming area, the priority of the second CAG information is higher Based on the priority of the first CAG information;

If the user equipment is in a roaming area, the priority of the second CAG information is higher than that of the first CAG information, and if the user equipment is in a non-roaming area, the priority of the first CAG information is higher Based on the priority of the second CAG information;

For the first network, the priority of the first CAG information is higher than the priority of the second CAG information, and for the second network, the priority of the second CAG information is higher than the priority of the first CAG information class;

For the first network, the priority of the second CAG information is higher than the priority of the first CAG information, and for the second network, the priority of the first CAG information is higher than the priority of the second CAG information class;

For the first CAG, the priority of the first CAG information is higher than the priority of the second CAG information, and for the second CAG, the priority of the second CAG information is higher than the priority of the first CAG information class;

For the first CAG, the priority of the second CAG information is higher than the priority of the first CAG information, and for the second CAG, the priority of the first CAG information is higher than the priority of the second CAG information class.

Wherein, the second CAG information includes:

CAG information stored in the non-volatile memory NV of the user equipment;

The CAG information stored in the global subscriber identity card USIM of the user equipment.

Further, the preset priority rules also include any of the following:

The CAG information stored in the NV has a higher priority than the CAG information stored in the USIM;

The priority of the CAG information stored in the USIM is higher than that of the CAG information stored in the NV.

In related technologies, when the network side does not send the CAG information, the user equipment will not be able to display the CAG information to the user, which will make it difficult for the user to perform manual CAG selection.

In some embodiments, the user equipment includes a mobile device, and before the user equipment presents the CAG information corresponding to the CAG ID to the user according to a preset priority rule, the method further includes the step of acquiring the second CAG information, Obtaining the second CAG information includes any of the following:

The mobile device uses the CAG ID to search in the local CAG information of the user equipment, and determines the second CAG information corresponding to the CAG ID;

The mobile device uses the network ID and the CAG ID to search in the local CAG information of the user equipment, and determines the second CAG information corresponding to the network ID and the CAG ID.

In this way, when the network side does not send the CAG information, the user equipment can still obtain the local second CAG information, and display the second CAG information to the user, so that the user can select a CAG.

When a CAG information can be uniquely determined by using the CAG ID, only the CAG ID can be used to search in the local CAG information of the user equipment to determine the second CAG information; when a CAG information cannot be uniquely determined by using the CAG ID, it is necessary to use The network ID+CAG ID is searched in the local CAG information of the user equipment to determine the second CAG information, where the network ID may specifically be the PLMN ID.

In some embodiments, the CAG information processing method also includes:

The mobile device searches for a CAG cell;

The mobile device receives the air interface message carrying the CAG information, and updates the CAG information in the air interface message to the user equipment.

Wherein, updating the CAG information in the air interface message to the user equipment includes:

If the user equipment stores a first CAG ID and CAG information 1 corresponding to the first CAG ID, the air interface message carries the first CAG ID and CAG information 2 corresponding to the first CAG ID , the CAG information 1 stored in the user equipment is updated to CAG information 2.

When updating CAG information, if the number of CAG information associated with the same PLMN exceeds the preset maximum number or the number of bytes of CAG information exceeds the preset maximum number of bytes, delete the CAG information with the earliest storage time.

The numbers 1 and 2 in CAG information 1 and CAG information 2 have no special meaning, and are only for distinguishing CAG information, wherein, CAG information 1 is the local CAG information of the user equipment corresponding to the first CAG ID, and CAG information 2 is CAG information in the air interface message corresponding to the first CAG ID.

In some embodiments, updating the CAG information 1 stored in the user equipment to CAG information 2 includes at least one of the following:

updating CAG information 1 stored in the USIM of the user equipment to CAG information 2;

The CAG information 1 stored in the NV of the user equipment is updated to CAG information 2.

In this embodiment, the user equipment can pre-configure the CAG HRNN and its related information such as the PLMN ID and the CAG ID in the USIM and/or NV. After the user equipment receives the CAG HRNN in the air interface message, it can update the received CAG HRNN to the USIM and/or NV. When the CAG HRNN needs to be displayed to the user, the relevant information of the CAG can be read from the CAG file in the USIM and/or NV, so as to obtain the name of the target CAG saved in the USIM and/or NV as the name displayed to the user.

When both the USIM and the air interface message of the user equipment have CAG HRNN, according to the preset priority rules, the CAG HRNN in the USIM can be displayed to the user, and the CAG HRNN sent in the air interface message can also be displayed to the user, that is, the CAG HRNN in the USIM CAG HRNN can be used as a higher priority, and the CAG HRNN sent in the air interface message can also be used as a higher priority.

In a specific example, as shown in Figure 7, the method for processing CAG information includes the following steps:

Step 101, the ME searches for a CAG cell, which may or may not broadcast the HRNN of the CAG;

Step 102, ME judges the received network information (such as PLMN ID, Tracking Area Code (TAC), CELL ID, CAG information, etc.), and can determine the use priority of CAG HRNN according to the preset priority principle , including the priority of storing CAG HRNN and the priority of displaying CAG HRNN. The priority principle can be implemented in several ways:

Method 1: Use the HRNN in the received air interface message first, that is, consider the HRNN in the air interface message to be the latest, secondly use the HRNN saved in the NV, and finally use the HRNN saved in the USIM.

Method 2: The priority of CAG HRNN can be determined according to the roaming situation: If you are currently in a roaming area, you can give priority to using the CAG HRNN broadcast by the cell. If the cell does not broadcast, you can use the HRNN locally saved by the UE, or you can not use HRNN; if you are currently in a non-roaming area, you can use the HRNN locally saved by the UE first, and then use the HRNN broadcast by the cell, or you can not use HRNN.

Wherein, the HRNN locally stored by the UE can be divided into the HRNN stored in the USIM and the HRNN stored in the NV. Further, it may be that the priority of the HRNN stored in the USIM is higher than that of the HRNN stored in the NV, or the priority of the HRNN stored in the NV is higher than that of the HRNN stored in the USIM.

Method 3: You can indicate the use priority of CAG HRNN in groups, for example:

For some networks, such as some PLMNs, or some CAGs, use the CAG HRNN in the air interface message first, and then use the HRNN locally saved by the UE; for other networks, use the HRNN locally saved by the UE first, and then use the HRNN in the air interface message;

Wherein, the HRNN locally stored by the UE can be divided into the HRNN stored in the USIM and the HRNN stored in the NV. Further, it may be that the priority of the HRNN stored in the USIM is higher than that of the HRNN stored in the NV, or the priority of the HRNN stored in the NV is higher than that of the HRNN stored in the USIM.

Step 103, the ME queries the CAG information locally stored in the UE;

The execution of this step may be based on the judgment of step 102, or may not go through the judgment of step 102; for example, in step 102, it is judged that the HRNN stored locally by the UE is preferred, and the CAG information stored locally by the UE needs to be queried.

Step 104, the CAG information stored locally by the UE is fed back to the ME;

Step 105, ME determines the usage of CAG HRNN. For example, if there is no CAG HRNN in the air interface message, it is decided to use the CAG HRNN locally stored by the UE.

Wherein, part of the judging steps in step 102 can be performed in this step.

Further, the processing method of CAG information also includes the following steps:

Step 201, after the ME receives the CAG HRNN in the air interface message, the UE can decide whether to update to UE local, including whether to update to USIM or NV. If it needs to be updated, send CAG HRNN and related information, such as PLMN ID, CAG ID, etc. to USIM or NV. In this way, when a cell that does not broadcast PLMN ID+CAG ID is encountered, the previously saved information can also be used to display CAG HRNN to the user.

Step 202, UE (such as USIM or NV) feeds back the local update result to ME.

In a specific embodiment, the CAG information may be stored in the USIM of the UE, assuming that the stored file is FILE_CAG. The length of the file FILE_CAG is variable length, the length is the number of bytes of the file FILE_CAG, a maximum length can be set, and the number of bytes of the file FILE_CAG does not exceed the maximum length.

The content of the file FILE_CAG can contain several first-level ENTRY, and each first-level ENTRY can contain:

1. PLMN ID.

2. CAG list, the PLMN in the ENTRY corresponds to a CAG list.

The CAG list includes several second-level entries, and each second-level entry indicates information about a CAG. The CAG is the CAG in the PLMN corresponding to the first-level ENTRY. The CAG information includes:

(1) CAG ID;

(2) CAG HRNN;

(3) It can also include a CAG icon (ICON), or a link to the CAG ICON.

If a first-level ENTRY does not contain a CAG list, it means that the PLMN ID has no corresponding CAG information;

If a secondary entry contains CAG ID, but does not contain CAG HRNN, it means that the PLMN+CAG ID has not set CAG HRNN in USIM;

If a secondary entry contains a CAG ID but does not contain a CAG ICON, it means that the PLMN+CAG ID does not have a CAG ICON set in the USIM;

In a specific example, the structure of the file FILE_CAG (excluding CAG ICON) is shown in the following table:

In another specific example, the structure of the file FILE_CAG (including CAG ICON) is shown in the following table:

In the file FILE_CAG, as shown in the above table, the first PLMN and the first CAG information corresponding to the PLMN can be used as the required file content. Then when the PLMN does not exist, the PLMN ID can be filled with an invalid value;

Of course, in the file FILE_CAG, as shown in the above table, the first K PLMNs and the CAG information corresponding to the K PLMNs can also be used as mandatory file content. Then when the K PLMNs do not exist, the PLMN ID can be filled with an invalid value, and K is an integer greater than 1;

In the file FILE_CAG, as shown in the above table, the first PLMN and the first CAG information corresponding to the PLMN can also be used as optional file content. When the file has no valid PLMN and its CAG information, the file length is 0.

For each secondary ENTRY, when the PLMN exists but the corresponding CAG information does not exist, it can be indicated by the length of the CAG information being 0. If the encoding method of the CAG information has an invalid value, the CAG information itself can also be used Invalid value representation for .

In this embodiment, the encoding format of PLMN ID, CAG ID, and CAG HRNN can refer to relevant communication protocols.

When reading the CAG information, the UE can read the entire CAG file into the ME. The UE can index in the file according to the PLMN ID+CAGID, find the ENTRY with the same PLMN ID+CAG ID, and use the CAG HRNN corresponding to the ENTRY as the CAG HRNN displayed to the user.

The operator can write the PLMN and CAG information to the file in the USIM when signing the contract. This file can also be updated during UE running. For example: After obtaining the PLMN+CAG ID+CAG HRNN from the air interface, such as the cell broadcast message, you can write the PLMN+CAG ID+CAG HRNN of the air interface into the file; if the PLMN+CAG ID already exists in the file, then Use the CAG HRNN in the cell broadcast message to cover the existing CAG HRNN.

The file storing CAG information may limit the maximum number of CAGs associated with each PLMN or the maximum number of bytes of CAG information, or may not limit the maximum number of CAGs associated with each PLMN or the maximum number of bytes of CAG information, and Only limit the length of the entire file. If the newly added information exceeds the maximum number of CAGs associated with the PLMN or the maximum number of bytes of CAG information, the oldest information can be deleted by moving and the latest information can be kept.

When displaying CAG information to the user, if the file storing the CAG information in the USIM has the same PLMN+CAG ID as the air interface message, but the corresponding CAG HRNN is different, it can be considered that the CAG HRNN in the air interface message has a higher priority. Display the CAG HRNN carried in the air interface message; if there is PLMN+CAG ID+CAGHRNN in the file storing CAG information in the USIM, but the air interface does not broadcast the CAG HRNN, then display the CAG HRNN in the file in the USIM to the user; if the file in the USIM If there is no PLMN+CAG ID+CAG HRNN, but the air interface broadcasts the CAG HRNN, then the CAG HRNN carried in the air interface message will be displayed to the user.

Of course, when displaying CAG information to the user, it can also be considered that the CAG HRNN stored in the USIM has a higher priority, and the CAG HRNN stored in the USIM is displayed to the user first; if there is no CAG HRNN stored in the USIM, but the CAG HRNN is broadcast over the air interface , then show the user the CAG HRNN carried in the air interface message.

The above embodiment is described by taking the storage of CAG information in the USIM of the UE as an example. The technical solution of the present invention can also store the CAG information in the NV of the UE. When storing the CAG information in the NV of the UE, the storage, reading, updating and The way of displaying the CAG information is similar to the way described in the above embodiment (storing the CAG information in the USIM of the UE), and will not be repeated here.
