Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments.

The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

The VPLMN includes an I-Network open Function (I-NEF), a Network Slice Selection Function (NSSF), a Network open Function (NEF), a Network Resource Function (NRF), a Policy Control Function (PCF), an Application Function (AF), an Access and Mobility Management Function (Access and Mobility Management Function, AMF), a Session Management Function (SMF), a Radio Access Network (RAN), a User Plane Function (User Plane Function, UPF), a Data Network (Data, DN), and the HPLMN includes a Unified Data Management Function (udd, Data Authentication Function (PCF), a service Server (PCF), and a Network Resource Function (NRF).

As shown in fig. 4, the User Equipment (UE) includes a Mobile Equipment (ME), where TE is a Terminal Equipment (Terminal Equipment), MT is a Mobile Terminal (Mobile Termination), USIM is a Universal Subscriber Identity Module (Universal Subscriber Identity Module), and the UE communicates with a Universal Mobile telecommunications system terrestrial Access Network (UMTS Radio Access Network, UTRAN), AN Evolved Universal Mobile telecommunications system terrestrial Access Network (Evolved UMTS Radio Access Network, E-UTRAN), a 5G Access Network (AN), and/or a Core Network (CN).

As shown in fig. 5, the TE (e.g. computer) and the MT may be integrated into the TE or the MT by using TA as an interface, which specifically includes the following ways:

TA, MT and TE are independent;

the TA is integrated with the MT, namely the TA is integrated in the MT, and the TE is taken as a single entity;

the TA is integrated with the TE, namely the TA is integrated in the TE, and the MT is taken as a single entity;

TA, MT and TE are integrated together.

Currently, the name of the operator may be stored in a Subscriber Identity Module (SIM) or a non-volatile memory (NV), or may be transmitted over the air interface. When carrier names coexist in a plurality of places, the priority ordering is performed by rules prescribed by the protocol.

Here, the human-readable network name (HRNN) of the CAG 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 broadcast in the system message of the cell. The CAG HRNN is used for showing a User (User) when the User manually selects CAG. In the current technology, when the air interface does not send the CAG HRNN, a human-readable name cannot be displayed to the user, which makes manual CAG selection difficult for the user.

An embodiment of the present invention provides a method for processing CAG information, which is applied to a user equipment, and as shown in fig. 6, the method includes:

step S1: the user equipment displays CAG information corresponding to the CAG identification ID to a user according to a preset priority rule, wherein the CAG information comprises at least one of the following items: the information processing method includes the steps of obtaining CAG names HRNN and CAG icon information, wherein the CAG information includes first CAG information and/or second CAG information, the first CAG information is CAG information in a received air interface message, and the second CAG information is CAG information local to the user equipment.

In this embodiment, the user equipment displays, to the user, the CAG information corresponding to the CAG ID according to a preset priority rule, where the CAG information includes the CAG information in the air interface message and local CAG information of the user equipment, and thus, when the air interface message does not carry the CAG information, the local CAG information of the user equipment may also be used to display to the user, so that the user selects a target CAG according to the CAG information.

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

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

the priority of the second CAG information is higher than that 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 than that 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 than that of the second CAG information;

for a first network, the priority of the first CAG information is higher than that of the second CAG information, and for a second network, the priority of the second CAG information is higher than that of the first CAG information;

for a first network, the priority of the second CAG information is higher than that of the first CAG information, and for a second network, the priority of the first CAG information is higher than that of the second CAG information;

for a first CAG, the priority of the first CAG information is higher than that of the second CAG information, and for a second CAG, the priority of the second CAG information is higher than that of the first CAG information;

for a first CAG, the priority of the second CAG information is higher than that of the first CAG information, and for a second CAG, the priority of the first CAG information is higher than that of the second CAG information.

Wherein the second CAG information includes:

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

CAG information stored in a universal subscriber identity card USIM of the user equipment.

Further, the preset priority rule further includes any one of the following:

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

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

In the related art, when the network side does not send the CAG information, the user equipment cannot show the CAG information to the user, which causes difficulty in manual CAG selection by the user.

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

the mobile equipment searches in the local CAG information of the user equipment by using the CAG ID and determines second CAG information corresponding to the CAG ID;

and the mobile equipment searches in the local CAG information of the user equipment by using the network ID and the CAG ID, and determines second CAG information corresponding to the network ID and the CAG ID.

Therefore, 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 CAG.

When the CAG ID can uniquely determine a piece of CAG information, only the CAG ID can be used for searching in the CAG information local to the user equipment to determine second CAG information; when a CAG information cannot be uniquely determined by using a CAG ID, a network ID + a CAG ID needs to be used to search in the CAG information local to the user equipment to determine a second CAG information, wherein the network ID may be specifically a PLMN ID.

In some embodiments, the method for processing CAG information further includes:

the mobile device searches for a CAG cell;

and the mobile equipment receives an air interface message carrying 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 comprises:

and if the user equipment stores a first CAG ID and CAG information 1 corresponding to the first CAG ID, and the air interface message carries the first CAG ID and CAG information 2 corresponding to the first CAG ID, updating the CAG information 1 stored by the user equipment into CAG information 2.

When the CAG information is updated, if the number of the CAG information associated with the same PLMN exceeds the preset maximum number or the byte number of the CAG information exceeds the preset maximum byte number, deleting the CAG information with the earliest storage time.

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

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

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

and updating the CAG information 1 stored in the NV of the user equipment into CAG information 2.

In this embodiment, the user equipment may pre-configure the CAG HRNN and its related information, such as PLMN ID and CAG ID, in the USIM and/or NV. After the user equipment receives the CAG HRNN in the air interface message, the received CAG HRNN may be updated to the USIM and/or NV. When the CAG HRNN needs to be presented to the user, the CAG related information can be read from a CAG file in the USIM and/or NV, so as to obtain the NAME of the target CAG stored in the USIM and/or NV as the NAME presented to the user.

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

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

step 101, the ME searches a CAG cell, and the cell may or may not broadcast the HRNN of the CAG;

step 102, the ME judges the received network information (such as PLMN ID, Tracking Area Code (TAC), CELL ID, CAG information, etc.), and may determine the usage priority of the CAG HRNN according to a preset priority principle, including the priority for storing the CAG HRNN and the priority for displaying the CAG HRNN. The priority principle can adopt the following modes:

the first method is as follows: the HRNN in the received air interface message is preferentially used, that is, the HRNN in the air interface message is considered to be the latest, the HRNN stored in the NV is used, and the HRNN stored in the USIM is used.

The second method comprises the following steps: the priority of the CAG HRNN may be determined according to the roaming situation: if the current cell is in the roaming area, the CAG HRNN broadcasted by the cell can be preferentially used. If the cell does not broadcast, the HRNN locally stored by the UE can be reused, or the HRNN is not used; if the current location is in the non-roaming area, the HRNN locally stored by the UE may be preferentially used, and then the HRNN broadcasted by the cell may be used, or the HRNN may not be used.

The HRNN locally stored in the UE may be further classified into an HRNN stored in the USIM and an HRNN stored in the NV. Further, the HRNN stored in the USIM may have a higher priority than the HRNN stored in the NV, or the HRNN stored in the NV may have a higher priority than the HRNN stored in the USIM.

The third method comprises the following steps: the usage priority of CAG HRNN may be indicated in groups, such as:

for some networks, such as some PLMNs or some CAGs, the CAG HRNN in the air interface message is preferentially used, and then the HRNN stored locally by the UE is used; for other networks, the HRNN locally stored by the UE is preferentially used, and then the HRNN in the air interface message is used;

103, the ME inquires CAG information stored locally in the UE;

this step may be performed based on the determination of step 102, or may not be performed through the determination of step 102; for example, if it is determined in step 102 that the HRNN locally stored in the UE is preferentially used, the CAG information locally stored in the UE needs to be queried.

Step 104, feeding back CAG information locally stored by the UE 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 determined to use the CAG HRNN locally stored by the UE.

Part of the determination step of step 102 may be performed at this step.

Further, the method for processing the CAG information further comprises the following steps:

in step 201, after the ME receives the CAG HRNN in the air interface message, the UE may determine whether to update to the UE local, including whether to update to the USIM or NV. If the update is needed, the CAG HRNN and the related information thereof, such as PLMN ID, CAG ID, etc., are sent to USIM or NV together. Thus, when a cell is encountered which does not broadcast the PLMN ID + CAG ID, the CAG HRNN may also be presented to the user using the information that was previously stored.

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

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

The content of FILE _ CAG may contain several primary entries, each of which may contain:

1、PLMN ID。

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

The CAG list includes a plurality of secondary entries, each secondary ENTRY indicates information of a CAG, the CAG is a CAG in a corresponding PLMN in the primary ENTRY, and the CAG information includes:

(1)CAG ID；

(2)CAG HRNN；

(3) a CAG ICON (ICON), or a link to the CAG ICON, may also be included.

If one primary ENTRY does not contain a CAG list, indicating that the PLMN ID does not have corresponding CAG information;

if one secondary entry contains the CAG ID but does not contain the CAG HRNN, the PLMN + CAG ID does not set the CAG HRNN in the USIM;

if one secondary entry contains the CAG ID but does not contain the CAG ICON, the PLMN + CAG ID does not set the CAG ICON in the USIM;

in a specific example, the structure of the FILE _ CAG (excluding CAG ICON) is shown in the following table:

in another specific example, the structure of the FILE _ CAG (including CAG ICON) is shown in the following table:

in the FILE _ CAG, as shown in the above table, the first PLMN and the first CAG information corresponding to the PLMN may be used as the content of the optional FILE. Then the PLMN ID may be filled with an invalid value when the PLMN does not exist;

of course, in the FILE _ CAG, as shown in the above table, the first K PLMNs and CAG information corresponding to the K PLMNs may also be used as the content of the optional FILE. Then the PLMN ID may be filled with invalid values when the K PLMNs do not exist, K being an integer greater than 1;

in the FILE _ CAG, as shown in the above table, the first PLMN and the first CAG information corresponding to the PLMN may also be used as the content of the selectable FILE. When the file does not have valid PLMN and CAG information thereof, it is represented by a file length of 0.

For each secondary ENTRY, when the PLMN exists but the corresponding CAG information does not exist, the length of the CAG information may be 0, and if the coding scheme of the CAG information has an invalid value, the coding scheme may also be represented by an invalid value of the CAG information itself.

In this embodiment, the coding formats of the PLMN ID, the CAG ID, and the CAG HRNN may refer to the relevant communication protocol.

In reading the CAG information, the UE may read the entire CAG file into the ME. The UE can index in the file according to the PLMN ID + CAG ID, and after finding the ENTRY of the same PLMN ID + CAG ID, the CAG HRNN corresponding to the ENTRY is used as the CAG HRNN displayed to the user.

The operator can write PLMN and CAG information to the file in the USIM at subscription. The file may also be updated during the UE operation. For example: after acquiring PLMN + CAG ID + CAG HRNN from the air interface, for example, a cell broadcast message, the PLMN + CAG ID + CAG HRNN of the air interface may be written into the file; if the PLMN + CAG ID already exists in the file, the existing CAG HRNN is covered by the CAG HRNN in the cell broadcast message.

The file storing the 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, but only limit the length of the whole 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 in a mobile manner, and the latest information is reserved.

When displaying the CAG information to the user, if the same PLMN + CAG ID exists in the file storing the CAG information in the USIM and the air interface message but the corresponding CAG HRNN is different, it may be considered that the CAG HRNN priority in the air interface message is higher, and the CAG HRNN carried in the air interface message is displayed to the user; if the files storing the CAG information in the USIM contain PLMN + CAG ID + CAG HRNN, but the empty port does not broadcast CAG HRNN, the CAG HRNN in the files in the USIM is displayed to the user; and if the file in the USIM does not contain the PLMN + CAG ID + CAG HRNN, but the air interface broadcasts the CAG HRNN, displaying the CAG HRNN carried in the air interface message to the user.

Certainly, when the CAG information is presented to the user, it may be considered that the CAG HRNN stored in the USIM has a higher priority, and the CAG HRNN stored in the USIM is preferentially presented to the user; and if the CAG HRNN is not stored in the USIM but the CAG HRNN is broadcast by the air interface, displaying the CAG HRNN carried in the air interface message to the user.

The foregoing embodiment takes the example of storing the CAG information in the USIM of the UE as an example, the technical solution of the present invention may also store the CAG information in the NV of the UE, and when the CAG information is stored in the NV of the UE, the manner of storing, reading, updating, and displaying the CAG information is similar to that described in the foregoing embodiment (storing the CAG information in the USIM of the UE), and is not described herein again.
