Background

With the development of communication technology, a fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) has emerged. The new frequency band, carrier wave and bandwidth are introduced in 5G, so that in order to support the wireless communication system established before 3GPP, such as radio resource control (Radio Resource Control, RRC) messages reported about the wireless capability of the terminal between the network where LTE,4G and 5G coexist and the multimode terminal, a lot of overhead is increased by signaling bands for transmitting the RRC messages to the network and the terminal.

In the conventional technology, in order to avoid frequent transmission of larger RRC messages between a terminal and 4G and 5G access network elements, the R16 standard proposes a method for allocating and reporting terminal wireless capability identifiers between the terminal and each network element, in addition to the original RRC layer wireless capability reporting mechanism.

However, in the conventional art, a terminal stores only one terminal wireless capability identification, but terminal wireless capability information is different in different areas. When the terminal moves in the areas with different wireless capability information, the process of inquiring the wireless capability of the terminal and the process of distributing the wireless capability identifier to the terminal need to be re-executed, and the cost of the network element and the signaling surface of the terminal can be increased.

Detailed Description

In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning.

Currently, with the development of communication technology, a fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) is emerging. The new frequency band, carrier wave and bandwidth are introduced in 5G, so that in order to support the wireless communication system established before 3GPP, such as radio resource control (Radio Resource Control, RRC) messages reported about the wireless capability of the terminal between the network where LTE,4G and 5G coexist and the multimode terminal, a lot of overhead is increased by signaling bands for transmitting the RRC messages to the network and the terminal. In addition, in some cases, the RRC message may reach 20 kbytes, and the PDU (protocol data unit) size of PDCP (PACKET DATA Convergence Protocol ) used for transmitting the RRC message is NR 9 kbytes and LTE 8188 bytes, respectively, so that when transmitting the RRC message, it is necessary to segment the RRC message with an extra length, which in turn increases the burden on the signaling plane of the network and the terminal.

In order to avoid frequent transmission of larger RRC messages or air interface segmentation messages between the terminal and 4G and 5G access network elements, the R16 standard proposes a method for allocating and reporting terminal wireless capability identifiers between the terminal and each network element besides the original RRC layer wireless capability reporting mechanism.

However, in one aspect, for a terminal supporting multiple systems, the capability-free configuration of the terminal may be dynamically changed according to the user requirement, for example, a certain wireless system is activated or deactivated, which results in a change in the combination of wireless systems of the terminal, that is, a change in the wireless capability configuration of the terminal. On the other hand, for an operator with a wide coverage area and capable of supporting multiple wireless communication systems, it is difficult to use a unified filtering parameter set for querying the wireless capability of the terminal in the whole network coverage. And, along with the construction and adjustment of the access network element, the filtering parameter set of the wireless capability query of the terminal also changes dynamically along with the change of the network. Thus, under the same operator network, a terminal may have multiple wireless capability identification values assigned by the operator. The terminal needs to report the correct wireless capacity identification value of the terminal according to the network requirements, the environment and the wireless capacity configuration of the terminal. However, the reporting process of the wireless capability identification value of the terminal is an optimization process and cannot replace the existing wireless capability inquiry reporting process of the RRC layer terminal. For example, when the filtering parameter set of the network query changes, the terminal cannot know the changed filtering parameter set in advance, so that the wireless capability identification value reported by the terminal is invalid, at this time, the network side can reinitiate the RRC layer terminal wireless capability query reporting process defined by the original protocol, and based on the new reporting result of the terminal, the network side reallocates the new terminal wireless capability identification value, and completes the optimization of terminal wireless capability reporting through the new terminal wireless capability identification value.

Specifically, if the terminal activates two wireless systems, namely NR and LTE, the process of acquiring and reporting the wireless capability identification value of the terminal in different location areas covered by the network element of the access and mobility management function AMF (ACCESS AND Mobility Management Function) is shown in fig. 1. In LTE networks, the procedure is similar, except that LTE non-access stratum messages are used between the supported network and the terminal. The left circular area in fig. 1 refers to the area covered by the AMF1 network element, the middle elliptical area refers to the area covered by the AMF2 network element, and the right elliptical area refers to the area covered by the AMF3 network element, UCMF (UE radio Capability Management Function) network elements. UCMF network elements store a large amount of terminal wireless capability information.

It is assumed that the radio capability configuration of the terminal 1 remains unchanged all the time, and the terminal capability filtering parameter sets of the base stations managed by the AMF1 network element and the AMF2 network element are the same, and the terminal capability filtering parameter sets of the base stations managed by the AMF3 network element are different from the other two AMF network elements.

And when the terminal moves to the area covered by the AMF1 network element, the initial registration is completed to acquire the wireless capability identification value 4. The specific process is shown in fig. 2. Step 201, a wireless capability identification value is not available in a terminal, and a wireless capability information query process of the terminal is executed first, wherein the process comprises the following steps: step 202, inquiring the wireless capability information of the terminal through the base station 2, step 203, and determining the wireless capability information 3 of the terminal under the terminal capability filtering parameter set of the base station managed by the AMF1 network element. And then executing a terminal wireless capability identification value allocation process, which comprises the following steps: step 204, the AMF1 network element obtains wireless capability information 3 from the base station 2; step 205, the obtained wireless capability information 3 is sent to UCMF network elements; 206, UCMF network element distributes wireless ability identification value 4 to AMF1 network element according to received wireless ability 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 fig. 3, in 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 reports the stored wireless capability identification value 4 to the AMF2 network element through the base station 2 corresponding to the AMF2 network element. Because the terminal capability filtering parameter sets of the base station managed by the AMF1 network element and the AMF2 network element are the same, the step 302, the AMF2 network element queries the UCMF network element through the reported wireless capability identification value 4, and determines whether the UCMF network element has the terminal wireless capability information 3 corresponding to the wireless capability identification value 4. Step 303, if yes, UCMF network element replies terminal wireless capability information 3 to AMF2 network element; step 304, the AMF2 network element replies the terminal wireless capability information 3 to the base station; the AMF2 network element sends a registration receiving message to the terminal through the base station.

As shown in fig. 4, in 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 reports the stored wireless capability identification value 4 to the AMF3 network element through the base station 2 corresponding to the AMF3 network element, and in step 402, the AMF3 network element queries UCMF about the wireless capability of the terminal, which specifically includes: the AMF3 network element inquires UCMF network elements according to the reported wireless capability identification value 4, and determines whether UCMF network elements have terminal wireless capability information 3 corresponding to the wireless capability identification value 4; step 403, if any, 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 a terminal wireless capability information query process; step 405, determining wireless capability information of a terminal under a terminal capability filtering parameter set of a base station managed by an AMF3 network element; step 406, the AMF3 network element acquires wireless capability information; step 407, the AMF3 network element sends the acquired wireless capability information to UCMF network element; step 408, obtaining a new wireless capability identification value 5; step 409, the new radio capability identification value 5 is returned to the terminal through the base station.

As shown in fig. 5, in step 501, when the terminal moves back to the area covered by the AMF1 network element, the terminal reports the stored wireless capability identification value 5 to the AMF1 network element through the base station 2 corresponding to the AMF1 network element; step 502, the AMF1 network element queries UCMF network elements for wireless capability of the terminal, and the specific process is as follows: the AMF1 network element inquires UCMF network elements according to the reported wireless capability identification value 5, and determines whether UCMF network elements have terminal wireless capability information corresponding to the wireless capability identification value 5; step 503, if any, the AMF1 network element returns the radio capability information to the base station 2. Step 504, the base station 2 determines that the received wireless capability information is inaccurate, and then executes a terminal wireless capability information query process; step 505, determining wireless capability information 3 of a terminal under a terminal capability filtering parameter set of a base station managed by an AMF1 network element; step 506, the AMF1 network element acquires wireless capability information 3; step 507, the AMF1 network element sends the acquired wireless capability information 3 to UCMF network elements; step 508, the AMF1 network element obtains a new wireless capability identification value 6; step 509, the new radio capability identification value 6 is returned to the terminal through the base station.

As can be seen from fig. 4 and fig. 5, in the case that the wireless capability configuration of the terminal itself is not changed, the terminal still needs a terminal wireless capability query procedure in the mobile process due to the different terminal wireless capability filtering parameter sets of the base stations managed by different AMF network elements.

The method for reporting the wireless capability identifier of the terminal provided by the embodiment of the application can be applied to an application environment shown in figure 1. The terminal 1 may be, but not limited to, various personal computers, notebook computers, tablet computers, and the like.

In one embodiment, as shown in fig. 6, a method for reporting a wireless capability identifier of a terminal is provided, and the embodiment is applied to the terminal for illustration by the method. In this embodiment, the method includes the steps of:

step 200, receiving a broadcast message sent by the access network device, wherein the broadcast message carries the target location area information.

The access network device may include an AMF network element and a base station, where the AMF network element may send a broadcast message through the base station, where the broadcast message includes a 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, the terminal receives the broadcast message sent by the AMF network element through the base station, and acquires the target location area information from the broadcast message, namely, the location area of the AMF network element where the terminal is located at the moment.

Step 210, determining that a wireless capability identifier corresponding to the target location area information is stored in the terminal, and reporting the stored wireless capability identifier to an access and mobility management function AMF network element.

After acquiring the target location area information, the terminal judges whether the wireless capability identifier corresponding to the target location area information is stored. If the terminal is determined to store the 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 identification reporting method provided by the embodiment of the application receives broadcast information carrying target location area information and sent by access network equipment; and when the wireless capability identifier corresponding to the target location area information is stored in the terminal, reporting the stored wireless capability identifier to the AMF network element. The method provided by the application has the advantages that the wireless capability identifiers corresponding to the information of different location areas are stored in the terminal, and when the terminal moves to the target location area, the wireless capability identifiers corresponding to the target location area are directly reported to the AMF network element. Therefore, when the terminal moves into the area covered by the AMF network element, the flow of the access network equipment for distributing the wireless capability identifier to the terminal is not needed, so that the cost brought by the flow of the access network equipment for distributing the wireless capability identifier to the terminal to the network element and the terminal signaling surface can be reduced, and the efficiency of the communication between the terminal and the access network equipment can be improved. In particular, the wireless capability information inquiry process of the terminal can be reduced.

In addition, in this embodiment, the broadcast message sent by the access network device is transmitted by using the original signaling between the terminal and the network element, so that no new signaling is required to be added, and the practicability of the method for reporting the wireless capability identifier of the terminal can be improved.

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 the correspondence between AMF information and wireless capability identification. 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, i.e., one AMF information corresponds to one location area information. Also stored in the first correspondence table may be a one-to-many correspondence between AMF information and location area information, that is, one AMF information corresponds to a plurality of location area information.

The second correspondence table may store a one-to-one correspondence between AMF information and wireless capability identifiers, that is, one AMF information corresponds to one wireless capability identifier. The second correspondence table may also store a many-to-one correspondence between AMF information and wireless capability identifiers, that is, a plurality of AMF information corresponds to one wireless capability identifier.

Based on the first corresponding relation table and the second corresponding relation table stored in the terminal, the terminal wireless capability identification reporting method further comprises the following steps:

And inquiring the first corresponding relation table and the second corresponding relation table based on the target location area information, and determining whether the wireless capability identifier corresponding to the target location area information is stored in the terminal.

After the terminal acquires the target location area information, the first corresponding relation table and the second corresponding relation table stored in the terminal are queried based on the target location area information so as to determine whether the wireless capability identifier corresponding to the target location area information is stored in the terminal. If the terminal inquires the wireless capability identifier corresponding to the target location area information in the first corresponding relation table and the second corresponding relation table based on the target location area information, determining that the wireless capability identifier corresponding to the target location area information is stored in the terminal; if the wireless capability identification corresponding to the target location area information is not queried in the first corresponding relation table and the second corresponding relation table based on the target location area information, the wireless capability identification corresponding to the target location area information is determined not to be stored in the terminal.

In this embodiment, whether the wireless capability identifier corresponding to the target location area information is stored in the terminal can be determined by querying the first correspondence table and the second correspondence table stored in the terminal, so that the logic is simple and convenient to implement.

In one embodiment, as shown in fig. 7, one possible implementation manner related to querying the first correspondence table and the second correspondence table based on the target location area information includes the steps of:

And 300, searching a first corresponding relation table based on the target position area information.

And if the corresponding relation between the AMF information and the location area information is stored in the first corresponding relation table, the terminal inquires whether the AMF information corresponding to the target location area information exists in the first corresponding relation table based on the target location area information.

Step 310, if the AMF information corresponding to the target location area information is found, the second correspondence table is found according to the found AMF information.

The second correspondence table is a correspondence between AMF information and wireless capability identifiers. If the terminal inquires AMF information corresponding to the target location area information in the first corresponding relation table, the terminal inquires whether the wireless capability information identifier corresponding to the inquired AMF information exists in the second corresponding relation table based on the inquired AMF information.

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

If the terminal inquires the wireless capability identifier corresponding to the inquired AMF information in the second corresponding relation table, the wireless capability identifier corresponding to the target location area information is stored in the terminal. If the terminal does not inquire the wireless capability identifier corresponding to the inquired AMF information in the second corresponding relation table, the wireless capability identifier corresponding to the target location area information is not stored in the terminal.

In this embodiment, a first correspondence table of correspondence between AMF information and location area information and a second correspondence table of correspondence between AMF information and wireless capability identification are stored in the terminal. After the terminal obtains the target location area information, the wireless capability identification corresponding to the target location area information can be rapidly and accurately determined by inquiring the first corresponding relation table and the second corresponding relation table.

In an optional embodiment, after the terminal obtains the first correspondence table and the second correspondence table, the terminal may determine a correspondence between the location area information and the wireless capability identifier according to a correspondence between AMF information in the first correspondence table and the location area information and a correspondence between AMF information in the second correspondence table and the wireless capability identifier, to form a third correspondence table.

Based on the third corresponding relation table, the terminal wireless capability identification reporting method further comprises the following steps: and inquiring the third corresponding relation table based on the target location area information to determine whether the wireless capability identification corresponding to the target location area information is stored in the terminal.

If the terminal can inquire the wireless capability identifier corresponding to the target location area information in the third corresponding relation table, the wireless capability identifier corresponding to the target location area information is stored in the terminal; if the wireless capability identification corresponding to the target location area information is not queried in the third corresponding relation table, the wireless capability identification corresponding to the target location area information is not stored in the terminal.

In one embodiment, the step of the terminal wireless capability identification reporting method further includes:

And determining that the wireless capability identifier corresponding to the target location area information is not stored in the terminal, initiating a wireless capability identifier acquisition process, and storing the wireless capability identifier acquired based on the wireless capability identifier acquisition process and AMF information into a first corresponding relation table and a second corresponding relation table.

If the terminal determines that the wireless capability identifier corresponding to the target location area information is not stored in the terminal, the terminal moves to the area covered by the AMF network element for the first time, and at this time, the terminal initiates a wireless capability identifier acquisition flow to the access network device so as to acquire the wireless capability identifier allocated by the access network device to the terminal and AMF information corresponding to the AMF network element. After obtaining the wireless capability identifier reassigned by the access network device, the terminal stores the wireless capability identifier and AMF information in a first corresponding relation table and a second corresponding relation 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 the AMF information acquired through the wireless capability identifier acquisition procedure are stored in the first correspondence table and the second correspondence table. When the terminal moves to the area covered by the AMF network element again, the wireless capability identification can be directly inquired in the first corresponding relation table and the second corresponding relation table, the wireless capability identification acquisition process is not required to be initiated again, and the cost brought to the network element and the terminal signaling surface can be reduced.

In one embodiment, as shown in fig. 8, one possible implementation related to initiating a wireless capability identification acquisition procedure includes the steps of:

Step 400, a registration request message is sent to the AMF network element.

The terminal sends a registration request message to the AMF network element through a base station in the access network equipment. The registration request message includes the wireless capability information of the terminal, the information of the AMF network element that the terminal has arrived before, and the like. Wherein, the context data of the AMF network element reached before the terminal, for example: encryption algorithms, integrity algorithms, etc. And if the wireless capability identifier corresponding to the target location area information is not stored in the terminal, the registration request information does not comprise the wireless capability identifier.

Step 410, receiving a registration receiving message sent by the AMF network element in response to the registration request message, where the registration receiving message includes a wireless capability identifier and AMF information.

After the AMF network element receives the registration request message, the AMF network element sends 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. UCMF the network element can generate a wireless capability identifier corresponding to the wireless capability information according to the wireless capability information of the terminal, and transmit the wireless capability identifier to the AMF network element.

The AMF network element sends a registration receive message to the terminal through the base station to inform the terminal that the registration is successful. The registration receiving message includes a wireless capability identifier corresponding to the wireless capability information of the terminal and AMF information corresponding to the AMF Wang Yu. That is, the terminal receives the wireless capability identification assigned by the access network device for the terminal.

In an optional embodiment, a wireless capability identifier corresponding to the wireless capability information of the terminal is stored in the AMF network element, and after receiving the registration request information, the AMF network element directly queries whether the wireless capability information contained in the registration request message exists in the AMF network element. If the AMF network element has the wireless capability information, directly transmitting a wireless capability information identifier corresponding to the wireless capability information to a terminal through a base station; if the AMF network element does not have the wireless capability information, the wireless capability information needs to be sent to UCMF network elements, and the wireless capability identifier corresponding to the wireless capability information is allocated through UCMF network elements.

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 overhead of the signaling plane between the network elements can be reduced.

In one embodiment, as shown in fig. 9, a possible implementation manner of storing the wireless capability identifier acquired based on the wireless capability identifier acquiring procedure and the AMF information in the first correspondence table and the second correspondence table is referred to, and the steps of the implementation manner include:

And 500, storing AMF information included in the registration receiving message and the target location area information in a first corresponding relation table.

The first correspondence table stores the correspondence between the AMF information and the location area information, and after receiving the registration receiving message, the terminal establishes the correspondence between the AMF information included in the registration receiving message and the target location area information acquired by the terminal from the broadcast message, and stores the correspondence, the AMF information and the target location area information in the first correspondence table.

Step 510, the AMF information included in the registration receive message and the wireless capability identifier included in the registration receive message are stored in the second correspondence table.

And the corresponding relation between the AMF information and the wireless capability identifier is stored in the second corresponding relation table, and after receiving the registration receiving message, the terminal establishes the corresponding relation between the AMF information and the wireless capability identifier, which are included in the registration receiving message, and stores the corresponding relation, the AMF information and the wireless capability identifier in the second corresponding relation table.

In this embodiment, the obtained wireless capability identifier, the target location area information and the AMF information are stored in the first correspondence table and the second correspondence table in correspondence, so that when the terminal moves 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, and therefore the efficiency of obtaining the wireless capability identifier of the terminal can be improved.

In one embodiment, as shown in fig. 10, the registration receiving message further includes a location area information list, which refers to another possible implementation manner of storing the wireless capability identifier acquired based on the wireless capability identifier acquiring procedure and AMF information in the first correspondence table and the second correspondence table, where the steps of the implementation manner include:

Step 600, the AMF information and the location area information list included in the registration receiving message are correspondingly stored in a first correspondence table.

The area covered by one AMF network element may include a plurality of location areas, and the registration receive message sent by the AMF network element to the terminal may include all location area information, that is, a location area information list, in the area covered by the AMF network element.

After receiving the registration receiving message, the terminal establishes a corresponding relation between the registration receiving message including AMF information and all the location area information in the location area list, namely, one AMF information corresponds to a plurality of location area information, and stores the corresponding relation, the AMF information and the location area information list in a first corresponding relation table.

Step 610, the AMF information included in the registration receive message and the wireless capability identifier included in the registration receive message are stored in the second correspondence table.

In this embodiment, the obtained wireless capability identifier, the location area list and the AMF information are stored in the first correspondence table and the second correspondence table correspondingly, so that when the terminal moves 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. And, one AMF information may correspond to a plurality of location area information, then a correspondence between the one AMF information and the plurality of location area information (location area list) is directly established and stored in the first correspondence table, so that the first correspondence table can be simplified, the subsequent query is facilitated, and the efficiency of querying the wireless capability identifier can be improved.

In a specific embodiment, the terminal wireless capability identification reporting method provided by the application stores the terminal wireless capability identification value 1 corresponding to the AMF1 network element and the terminal wireless capability identification value 2 corresponding to the AMF3 network element in the terminal. As shown in fig. 11, in 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 searches the wireless capability identification value 4 corresponding to the AMF1 network element according to the target location area information, and sends the wireless capability identification value 4 to the AMF1 network element through the base station. Step 1102, the AMF1 network element queries the UCMF network element for terminal wireless capability, determines whether there is terminal wireless capability information corresponding to the wireless capability identification value 4 in the UCMF network element, and if yes, the AMF1 network element sends a registration receiving message to the terminal through the base station in step 1103.

As shown in fig. 12, in one embodiment, the present application provides a method for reporting a wireless capability identifier of a terminal, where the method includes the steps of:
