Detailed ways

In order to make the above objects, features and advantages of the present application more obvious and easy to understand, the specific implementation modes of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described here. Those skilled in the art can make similar improvements without violating the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

The serial numbers assigned to components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning.

Currently, with the development of communication technology, the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) has emerged. 5G introduces new frequency bands, carriers and bandwidths. In order to support wireless communication standards developed before 3GPP, such as LTE, 4G and 5G coexistence networks and multi-mode terminals report Radio Resource Control (Radio Resource Control, RRC) messages will increase a lot, and transmitting RRC messages will bring significant overhead to the signaling plane of the network and terminals. In addition, in some cases, the RRC message can reach 20K bytes, and the size of the PDU (Protocol Data Unit) of PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol) used to transmit RRC messages is NR 9K bytes and NR respectively. LTE 8188 bytes, when transmitting RRC messages, the ultra-long RRC messages need to be transmitted in segments, which will increase the burden on the signaling plane of the network and terminals.

In order to avoid frequent transmission of large RRC messages or air interface segment messages between terminals and 4G and 5G access network elements, the R16 standard proposes that in addition to the original RRC layer wireless capability reporting mechanism, terminals and each network element Through the method of allocating and reporting the terminal wireless capability identification.

However, on the one hand, for a terminal that supports multiple standards, the terminal's unnecessary capability configuration can be dynamically changed according to user needs, such as activating or deactivating a certain wireless standard, causing the terminal's wireless standard combination to change, that is, the terminal's wireless standard combination changes. The wireless capability configuration of the terminal has changed. On the other hand, for an operator with a wide coverage area and the ability to support multiple wireless communication standards, it is difficult to use a unified filtering parameter set for terminal wireless capability query throughout the entire network coverage. Moreover, with the construction and adjustment of access network elements, the filtering parameter set for terminal wireless capability query will also dynamically change with network changes. Therefore, under the same operator's network, a terminal will have multiple wireless capability identification values allocated by the operator. The terminal needs to report the correct terminal wireless capability identification value based on the network requirements, the environment and its own wireless capability configuration. However, the reporting process of the terminal wireless capability identification value is an optimization process and cannot replace the existing RRC layer terminal wireless capability query and reporting process. For example, when the filtering parameter set of the network query changes, the terminal cannot know the changed filtering parameter set in advance, causing the wireless capability identification value reported by the terminal to be invalid. At this time, the network side will re-initiate the RRC layer terminal wireless capability query defined by the original protocol. In the reporting process, based on the new reporting result of the terminal, the network side redistributes a new terminal wireless capability identification value. Through this new terminal wireless capability identification value, the optimization of the terminal wireless capability reporting is completed.

Specifically, if the terminal activates both NR and LTE wireless standards, the access and mobility management function AMF (Access and Mobility The process of obtaining and reporting the wireless capability identification value of the terminal in different location areas covered by the Management Function network element is shown in Figure 1. In LTE networks, the process is similar, except for the supported LTE non-access layer messages used between the network and the terminal. The circular area on the left in Figure 1 refers to the area covered by the AMF1 network element, the elliptical area in the middle refers to the area covered by the AMF2 network element, and the elliptical area on the right refers to the area covered by the AMF3 network element. UCMF (UE radio Capability Management Function ) network element. A large amount of terminal wireless capability information is stored in the UCMF network element.

Assume that the wireless capability configuration of terminal 1 remains unchanged, the terminal capability filtering parameter set of the base station managed by AMF1 network element and AMF2 network element are the same, and the terminal capability filtering parameter set of the base station managed by AMF3 network element is the same as that of the other two AMF network elements. different.

When the terminal moves to the area covered by the AMF1 network element, it completes the initial registration and obtains the wireless capability identification value 4. The specific process is shown in Figure 2. Step 201: There is no wireless capability identification value in the terminal. First, perform the terminal wireless capability information query process. The process includes: Step 202: Query the terminal's wireless capability information through the base station 2. Step 203: Confirm that the terminal is managed by the AMF1 network element. Wireless capability information 3 under the terminal capability filtering parameter set of the base station. Then execute the terminal wireless capability identification value allocation process, which includes: step 204, the AMF1 network element obtains the wireless capability information 3 from the base station 2; step 205, and sends the acquired wireless capability information 3 to the UCMF network element; step 206, The UCMF network element allocates the wireless capability identification value 4 to the AMF1 network element according to the received wireless capability information 3; step 207, the AMF1 network element sends the wireless capability identification value 4 to the terminal through the base station 2 corresponding to the AMF1 network element.

As shown in Figure 3, step 301: When the terminal moves from the area covered by the AMF1 network element to the area covered by the AMF2 network element, the terminal will report its stored wireless capability identification value 4 to AMF2 through the base station 2 corresponding to the AMF2 network element. network element. Since the terminal capability filtering parameter sets of the base stations managed by the AMF1 network element and the AMF2 network element are the same, in step 302, the AMF2 network element queries the UCMF network element through the reported wireless capability identification value 4 to determine whether the UCMF network element has the same wireless capability. The terminal wireless capability information 3 corresponding to the identification value 4. Step 303. If yes, the UCMF network element will reply the terminal wireless capability information 3 to the AMF2 network element; Step 304, the AMF2 network element will reply the terminal wireless capability information 3 to the base station; the AMF2 network element will send a registration reception message to the terminal through the base station.

As shown in Figure 4, step 401: When the terminal moves from the area covered by the AMF2 network element to the area covered by the AMF3 network element, the terminal will report its stored wireless capability identification value 4 to AMF3 through the base station 2 corresponding to the AMF3 network element. Network element, step 402. The AMF3 network element queries UCMF for the terminal wireless capability. The specific process is: the AMF3 network element will query the UCMF network element based on the reported wireless capability identifier value 4 to determine whether the UCMF network element has the wireless capability identifier. The terminal wireless capability information 3 corresponding to the value 4; Step 403. If yes, the AMF3 network element returns the wireless capability information 3 to the base station 2; Step 404, the base station 2 determines that the received wireless capability information 3 is inaccurate, and then executes the terminal wireless capability information Information query process; step 405, determine the wireless capability information of the terminal under the terminal capability filtering parameter set of the base station managed by the AMF3 network element; step 406, the AMF3 network element obtains the wireless capability information; step 407, the wireless capability that the AMF3 network element will obtain The information is sent to the UCMF network element; step 408, obtain the new wireless capability identification value 5; step 409, return the new wireless capability identification value 5 to the terminal through the base station.

As shown in Figure 5, step 501, when the terminal moves back to the area covered by the AMF1 network element, the terminal will report its stored wireless capability identification value 5 to the AMF1 network element through the base station 2 corresponding to the AMF1 network element; step 502, AMF1 network element queries UCMF network element The specific process of terminal wireless capability is: AMF1 network element will query the UCMF network element based on the reported wireless capability identifier value 5 to determine whether there is terminal wireless capability information corresponding to the wireless capability identifier value 5 in the UCMF network element; step 503. If so, the AMF1 network element returns the wireless capability information to the base station 2. Step 504: The base station 2 determines that the received wireless capability information is inaccurate, and then performs the terminal wireless capability information query process; Step 505: Determines the wireless capability information of the terminal under the terminal capability filtering parameter set of the base station managed by the AMF1 network element 3; Step 506. The AMF1 network element obtains the wireless capability information 3; Step 507. The AMF1 network element sends the obtained wireless capability information 3 to the UCMF network element; Step 508. The AMF1 network element obtains the new wireless capability identification value 6; Step 509. The wireless capability identification value 6 is returned to the terminal through the base station.

It can be seen from Figure 4 and Figure 5 that when the wireless capability configuration of the terminal itself does not change, because the terminal wireless capability filtering parameter sets of base stations managed by different AMF network elements are different, the terminal still needs terminal wireless capabilities during the movement process. query process.

The terminal wireless capability identifier reporting method provided by the embodiment of the present application can be applied in the application environment as shown in Figure 1. The terminal 1 may be, but is not limited to, various personal computers, notebook computers, tablet computers, etc.

In one embodiment, as shown in Figure 6, a method for reporting a terminal wireless capability identifier is provided. This embodiment illustrates the application of this method to a terminal. In this embodiment, the method includes the following steps:

Step 200: Receive a broadcast message sent by the access network device, where the broadcast message carries target location area information.

The access network equipment may include an AMF network element and a base station. The AMF network element will send a broadcast message through the base station. The broadcast message includes the location area of the AMF network element to which the base station belongs. After the terminal moves into the area covered by the AMF network element, it will receive the broadcast message sent by the AMF network element through the base station, and obtain the target location area information from the broadcast message, that is, obtain the information of the AMF network element where the terminal is located at this time. location area.

Step 210: Determine that the wireless capability identifier corresponding to the target location area information is stored in the terminal, and report the stored wireless capability identifier to the access and mobility management function AMF network element.

After acquiring the target location area information, the terminal determines whether it stores a wireless capability identifier corresponding to the target location area information. If it is determined that the terminal stores a wireless capability identifier corresponding to the target location area information, the wireless capability identifier is directly reported to the AMF network element. Specifically, the terminal transmits the stored wireless capability identifier to the base station, and the base station transmits the received wireless capability identifier to the AMF network element.

The terminal wireless capability identifier reporting method provided by the embodiment of the present application receives the broadcast information carrying the target location area information sent by the access network device; and when the wireless capability identifier corresponding to the target location area information is stored in the terminal, the stored wireless capability identifier is stored in the terminal. The wireless capability identification is reported to the AMF network element. The method provided by this application stores wireless capability identifiers corresponding to different location area information in the terminal. When the terminal moves to the target location area, the wireless capability identifier corresponding to the target location area is directly reported to the AMF network element. In this way, when the terminal moves to the area covered by the AMF network element, there is no need for the access network device to allocate the wireless capability identifier to the terminal. This can reduce the impact of the access network device on the network element and terminal information. The overhead caused by the command surface can thereby improve the efficiency of communication between terminals and access network equipment. Specifically, the wireless capability information query process of the terminal can be reduced.

In addition, in this embodiment, the broadcast message sent by the access network device is transmitted using the original signaling between the terminal and the network element, without adding Adding new signaling can improve the practicality of the method for reporting terminal wireless capability identifiers.

In one embodiment, a first correspondence table and a second correspondence table are stored in the terminal. The first correspondence table stores the correspondence between AMF information and location area information, and the second correspondence table stores AMF information. The corresponding relationship with the wireless capability identifier. Specifically, the AMF information may be an AMF identification (AMF id).

Stored in the first correspondence table may be a one-to-one correspondence between AMF information and location area information, that is, one AMF information corresponds to one location area information. What is stored in the first correspondence table may also be a one-to-many correspondence between AMF information and location area information, that is, one AMF information corresponds to multiple location area information.

Stored in the second correspondence table may be a one-to-one correspondence between AMF information and wireless capability identifiers, that is, one AMF information corresponds to one wireless capability identifier. Stored in the second correspondence table may also be a many-to-one correspondence between AMF information and wireless capability identifiers, that is, multiple AMF information corresponds to one wireless capability identifier.

Based on the first correspondence table and the second correspondence table stored in the terminal, the terminal wireless capability identification reporting method further includes:

Query the first correspondence table and the second correspondence table based on the target location area information to determine whether the wireless capability identifier corresponding to the target location area information is stored in the terminal.

After acquiring the target location area information, the terminal queries the first correspondence table and the second correspondence table stored inside the terminal based on the target location area information to determine whether a wireless capability identifier corresponding to the target location area information is stored in the terminal. . If the terminal queries the wireless capability identifier corresponding to the target location area information in the first correspondence table and the second correspondence table based on the target location area information, it is determined that the wireless capability identifier corresponding to the target location area information is stored in the terminal; if If the terminal does not query the wireless capability identifier corresponding to the target location area information in the first correspondence table and the second correspondence table based on the target location area information, it determines that the wireless capability identifier corresponding to the target location area information is not stored in the terminal.

In this embodiment, by querying the first correspondence table and the second correspondence table stored inside the terminal, it can be determined whether the terminal stores a wireless capability identifier corresponding to the target location area information. The logic is simple and easy to implement.

In one embodiment, as shown in Figure 7, it involves a possible implementation of querying the first correspondence table and the second correspondence table based on target location area information. The steps of this implementation include:

Step 300: Search the first correspondence table based on the target location area information.

The first correspondence table stores the correspondence between AMF information and location area information. The terminal queries the first correspondence table based on the target location area information to see whether there is AMF information corresponding to the target location area information.

Step 310: If the AMF information corresponding to the target location area information is queried, query the second correspondence table according to the queried AMF information.

The second correspondence table is the correspondence between the AMF information and the wireless capability identifier. If the terminal queries the AMF information corresponding to the target location area information in the first correspondence table, the terminal queries whether there is a wireless capability corresponding to the queried AMF information in the second correspondence table based on the queried AMF information. Information identification.

If the terminal does not query the AMF information corresponding to the target location area information in the first correspondence table, it cannot query the wireless capability identifier corresponding to the AMF information in the second correspondence table, which means that the terminal does not store the AMF information corresponding to the target location area. The wireless capability identifier corresponding to the zone information.

If the terminal queries the wireless capability identifier corresponding to the queried AMF information in the second correspondence table, it means that the wireless capability identifier corresponding to the target location area information is stored in the terminal. If the terminal does not query the wireless capability identifier corresponding to the queried AMF information in the second correspondence table, it means that the wireless capability identifier corresponding to the target location area information is not stored in the terminal.

In this embodiment, the terminal internally stores a first correspondence table of correspondences between AMF information and location area information, and a second correspondence table of correspondences between AMF information and wireless capability identifiers. After acquiring the target location area information, the terminal can quickly and accurately determine the wireless capability identifier corresponding to the target location area information by querying the first correspondence table and the second correspondence table.

In an optional embodiment, after obtaining the first correspondence table and the second correspondence table, the terminal may use the correspondence between the AMF information and the location area information in the first correspondence table, and the second correspondence The correspondence between the AMF information and the wireless capability identifier in the relationship table determines the correspondence between the location area information and the wireless capability identifier, forming a third correspondence table.

Based on the above third correspondence table, the terminal wireless capability identifier reporting method further includes: querying the third correspondence table based on the target location area information to determine whether the wireless capability identifier corresponding to the target location area information is stored in the terminal.

If the terminal can query the wireless capability identifier corresponding to the target location area information in the third correspondence table, it means that the terminal stores the wireless capability identifier corresponding to the target location area information; if the terminal does not have the wireless capability identifier corresponding to the target location area information in the third correspondence table. If the wireless capability identifier corresponding to the target location area information is queried, it means that the wireless capability identifier corresponding to the target location area information is not stored in the terminal.

In one embodiment, the steps of the terminal wireless capability identification reporting method further include:

Determine that the wireless capability identifier corresponding to the target location area information is not stored in the terminal, initiate the wireless capability identifier acquisition process, and store the wireless capability identifier and AMF information obtained based on the wireless capability identifier acquisition process into the first correspondence table and the third Two corresponding relationships in the table.

If the terminal determines that the wireless capability identifier corresponding to the target location area information is not stored internally, it means that the terminal moves to the area covered by the AMF network element for the first time. At this time, the terminal initiates the wireless capability identifier acquisition process to the access network device to obtain the access network element. The wireless capability identifier assigned by the network access device to the terminal and the AMF information corresponding to the AMF network element. After acquiring the wireless capability identifier reallocated by the access network device, the terminal stores the wireless capability identifier and the AMF information in the first correspondence table and the second correspondence table.

In this embodiment, when the wireless capability identifier corresponding to the target location area information is not stored in the terminal, the wireless capability identifier and AMF information obtained through the wireless capability identifier acquisition process are stored in the first correspondence table and the second correspondence table. in the relationship table. In this way, when the terminal moves to the area covered by the AMF network element again, it can directly query the wireless capability identifier in the first correspondence table and the second correspondence table. It does not need to initiate the wireless capability identifier acquisition process again, which can reduce the need for network elements. and the overhead caused by the terminal signaling plane.

In one embodiment, as shown in Figure 8, it involves a possible implementation of initiating a wireless capability identity acquisition process. The steps of this implementation include:

Step 400: Send a registration request message to the AMF network element.

The terminal sends a registration request message to the AMF network element through the base station in the access network equipment. The registration request message includes the wireless capability information of the terminal and the information of the AMF network elements that the terminal has arrived at before. Among them, the context data of the AMF network elements that the terminal has arrived at before, such as encryption algorithm and integrity algorithm, etc. If the wireless capability identifier corresponding to the target location area information is not stored in the terminal, the registration request information does not include the wireless capability identifier.

Step 410: Receive the registration reception message sent by the AMF network element in response to the registration request message. The registration reception message includes the wireless capability identifier and AMF information.

After receiving the registration request message, the AMF network element will send the wireless capability information of the terminal in the registration request message to the terminal wireless capability management function UCMF (UE radio Capability Management Function) network element. The UCMF network element can generate a wireless capability identifier corresponding to the wireless capability information according to the terminal's wireless capability information, and transmit the wireless capability identifier to the AMF network element.

The AMF network element will send a registration reception message to the terminal through the base station to inform the terminal that the registration is successful. The registration reception message includes the wireless capability identifier corresponding to the wireless capability information of the terminal, and the AMF information corresponding to the AMF Wang Yu. That is to say, the terminal will receive the wireless capability identifier assigned to the terminal by the access network device.

In an optional embodiment, the wireless capability identifier corresponding to the terminal wireless capability information is stored in the AMF network element. After receiving the registration request information, the AMF network element directly queries the AMF network element to see whether there is a registration request message. Wireless capability information contained in . If the wireless capability information exists in the AMF network element, the wireless capability information identifier corresponding to the wireless capability information is directly sent to the terminal through the base station; if the wireless capability information does not exist in the AMF network element, the wireless capability information needs to be sent to The UCMF network element allocates the wireless capability identifier corresponding to the wireless capability information through the UCMF network element.

In this embodiment, by storing the wireless capability identifier corresponding to the terminal wireless capability information in the AMF network element, the query process between the AMF network element and the UCMF network element can be reduced to a certain extent, and the signaling interface between network elements can be reduced. s expenses.

In one embodiment, as shown in Figure 9, it involves a possible implementation of storing the wireless capability identifier and AMF information obtained based on the wireless capability identifier acquisition process into the first correspondence table and the second correspondence table. , the steps of this implementation include:

Step 500: Correspondingly store the AMF information included in the registration reception message and the target location area information into the first correspondence table.

The first correspondence table stores the correspondence between AMF information and location area information. After receiving the registration reception message, the terminal establishes the AMF information included in the registration reception message and the target location obtained by the terminal from the broadcast message. The corresponding relationship between the area information, and the corresponding relationship, the AMF information and the target location area information are stored in the first correspondence table.

Step 510: Correspondingly store the AMF information included in the registration reception message and the wireless capability identifier included in the registration reception message into the second correspondence table.

The second correspondence table stores the correspondence between the AMF information and the wireless capability identifier. After receiving the registration reception message, the terminal establishes the correspondence between the AMF information included in the registration reception message and the wireless capability identifier. And store the corresponding relationship, AMF information and wireless capability identifier in the second corresponding relationship table.

In this embodiment, by correspondingly storing the obtained wireless capability identifier, target location area information and AMF information in the first correspondence table and the second correspondence table, it is convenient for the terminal to move to the target location area information again. , the wireless capability identifier corresponding to the target location area information can be quickly queried from the first correspondence table and the second correspondence table, thereby improving the efficiency of obtaining the terminal wireless capability identifier.

In one embodiment, as shown in Figure 10, the registration reception message also includes a location area information list, which involves storing the wireless capability identifier and AMF information obtained based on the wireless capability identifier acquisition process into the first correspondence table and the second correspondence table. Another possible implementation in a relational table, the steps of this implementation include:

Step 600: Correspondingly store the AMF information included in the registration reception message and the location area information list into the first correspondence table.

The area covered by an AMF network element may include multiple location areas. The registration reception message sent by the AMF network element to the terminal may include all location area information in the area covered by the AMF network element, that is, a location area information list.

After receiving the registration reception message, the terminal establishes a correspondence between the AMF information included in the registration reception message and all location area information in the location area list, that is, one AMF information corresponds to multiple location area information, and combines the correspondence relationship with the AMF The information and the location area information list are stored in the first correspondence table.

Step 610: Store the AMF information included in the registration reception message and the wireless capability identifier included in the registration reception message into the second correspondence table.

In this embodiment, by correspondingly storing the obtained wireless capability identifier, location area list and AMF information in the first correspondence table and the second correspondence table, it is convenient for the terminal to move to the target location area information again. The wireless capability identifier corresponding to the target location area information can be queried from the first correspondence table and the second correspondence table. Moreover, one AMF information may correspond to multiple location area information, so the correspondence between one AMF information and multiple location area information (location area list) is directly established and stored in the first correspondence table, which can simplify the first correspondence. The relational table facilitates subsequent queries and can improve the efficiency of querying wireless capability identifiers.

In a specific embodiment, the terminal wireless capability identifier reporting method provided by this application is used to store the terminal wireless capability identifier value 1 corresponding to the AMF1 network element and the terminal wireless capability identifier value 2 corresponding to the AMF3 network element in the terminal. As shown in Figure 11, step 1101: When the terminal moves from the area covered by the AMF3 network element back to the area covered by the AMF1 network element, the terminal finds the wireless capability identification value 4 corresponding to the AMF1 network element based on the target location area information, and sets the The wireless capability identification value 4 is sent to the AMF1 network element through the base station. Step 1102. The AMF1 network element queries the UCMF network element for the terminal wireless capability and determines whether there is terminal wireless capability information corresponding to the wireless capability identification value 4 in the UCMF network element. Step 1103. If so, the AMF1 network element queries the terminal through the base station. Send registration to receive messages.

As shown in Figure 12, in one embodiment, an embodiment of the present application provides a method for reporting a terminal wireless capability identifier. The steps of the method include:
