Background
With the development of Communication technology, a fifth Generation Mobile Communication technology (5 th Generation Mobile Communication technology, 5G) appeared.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are 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. This application is capable of embodiments in many different forms than those described herein and that modifications may be made by one skilled in the art without departing from the spirit and scope of the application and it is therefore not intended to be limited to the specific embodiments disclosed below.
The ordinal numbers used herein for the components, such as "first," "second," etc., are used merely to distinguish between the objects described, and do not have any sequential or technical meaning.
Currently, with the development of Communication technology, a fifth Generation Mobile Communication technology (5 g) appears. The 5G introduces a new frequency band, a new carrier and a new bandwidth, in order to support a wireless communication system formulated by the 3GPP, for example, 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 will increase a lot, and a large overhead is brought to the signaling plane 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) of the PDCP (Packet Data Convergence Protocol) for transmitting the RRC message has NR 9 kbytes and LTE 8188 kbytes, respectively, so that when the RRC message is transmitted, the very long RRC message needs to be transmitted in segments, which increases the signaling burden of the network and the terminal.
In order to avoid frequent transmission of large RRC messages or air interface segmentation messages between the terminal and the 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 an original RRC layer wireless capability reporting mechanism.
However, on one hand, for a terminal supporting multiple systems, the configuration of the terminal that is not needed to be configured may be dynamically changed according to the user requirement, for example, a certain wireless system is activated or deactivated, which causes the combination of the wireless systems of the terminal to change, that is, the configuration of the wireless capability of the terminal changes. 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 uniform filtering parameter set for terminal wireless capability query in the whole network coverage. And, with the construction and adjustment of the access network element, the filtering parameter set of the terminal wireless capability query will also dynamically change with the network change. Therefore, under the same operator network, one terminal has a plurality of wireless capability identification values allocated by the operator. The terminal needs to report a correct terminal wireless capability identification value according to network requirements, the environment and the wireless capability configuration of the terminal. However, the reporting process of the radio capability identifier value of the terminal is an optimization process and cannot replace the existing RRC layer terminal radio capability query reporting process. For example, when the filtering parameter set queried by the network changes, the terminal cannot know the changed filtering parameter set in advance, which results in invalidity of the wireless capability identifier value reported by the terminal, and at this time, the network side re-initiates 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 re-allocates a new terminal wireless capability identifier value, and the optimization of the terminal wireless capability report is completed through the new terminal wireless capability identifier value.
Specifically, if the terminal activates two wireless systems, NR and LTE, a process of acquiring and reporting a wireless capability identifier value of the terminal in different location areas covered by Access and Mobility Management Function (AMF) network elements is shown in fig. 1. In LTE networks, the process is similar, with the difference being LTE non-access stratum messages used between the supported network and the terminal. In fig. 1, the left circular area refers to an area covered by an AMF1 network element, the middle elliptical area refers to an area covered by an AMF2 network element, the right elliptical area refers to an area covered by an AMF3 network element, and a UCMF (UE radio Capability Management Function) network element. The UCMF network element stores a large amount of terminal wireless capability information.
Assuming that the radio capability configuration of the terminal 1 is always kept unchanged, 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 set of the base station managed by the AMF3 network element is different from those of the other two AMF network elements.
And when the terminal moves to an area covered by the AMF1 network element, finishing initial registration to acquire a wireless capability identification value 4. The specific process is shown in fig. 2. Step 201, if there is no wireless capability identification value in the terminal, first executing a terminal wireless capability information query process, which includes: step 202, inquiring the wireless capability information of the terminal from 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, wherein the process comprises the following steps: step 204, the AMF1 network element acquires wireless capability information 3 from the base station 2; step 205, sending the acquired wireless capability information 3 to a UCMF network element; step 206, the UCMF network element allocates a 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 identifier 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 radio capability identifier 4 to the AMF2 network element through the base station 2 corresponding to the AMF2 network element. Since the AMF1 network element and the AMF2 network element manage the same terminal capability filtering parameter set of the base station, 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, the UCMF network element replies terminal wireless capability information 3 to the AMF2 network element; step 304, the AMF2 network element replies terminal wireless capability information 3 to the base station; and 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 identifier 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 the UCMF for the wireless capability of the terminal, which includes the specific processes: the AMF3 network element inquires the UCMF network element according to the reported wireless capability identification value 4, and determines whether the UCMF network element has terminal wireless capability information 3 corresponding to the wireless capability identification value 4; step 403, if yes, the AMF3 network element returns the radio capability information 3 to the base station 2; step 404, if the base station 2 determines that the received wireless capability information 3 is not accurate, the process of inquiring the wireless capability information of the terminal is executed; 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 obtains the wireless capability information; step 407, the AMF3 network element sends the acquired wireless capability information to the UCMF network element; step 408, acquiring a new wireless capability identification value of 5; and step 409, returning the new wireless capability identification value 5 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 radio capability identifier 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 the UCMF network element for the wireless capability of the terminal, and the specific process is as follows: the AMF1 network element inquires the UCMF network element according to the reported wireless capability identification value 5, and determines whether the UCMF network element has terminal wireless capability information corresponding to the wireless capability identification value 5; step 503, if yes, the AMF1 network element returns the radio capability information to the base station 2. Step 504, if the base station 2 determines that the received wireless capability information is not accurate, the process of inquiring the wireless capability information of the terminal is executed; step 505, determining wireless capability information 3 of the terminal under a terminal capability filtering parameter set of a base station managed by an AMF1 network element; step 506, the AMF1 network element obtains the wireless capability information 3; step 507, the AMF1 network element sends the acquired wireless capability information 3 to the UCMF network element; step 508, the AMF1 network element obtains a new wireless capability identification value 6; step 509, the new wireless capability identifier value 6 is returned to the terminal through the base station.
As can be seen from fig. 4 and 5, in the case that the radio capability configuration of the terminal itself is not changed, the terminal still needs the terminal radio capability query process during the moving process due to the difference in the terminal radio capability filtering parameter sets of the base stations managed by different AMF network elements.
The method for reporting the terminal wireless capability identifier provided by the embodiment of the application can be applied to the application environment shown in fig. 1. The terminal 1 may be, but is not limited to, various personal computers, notebook computers, tablet computers, and the like.
In an embodiment, as shown in fig. 6, a method for reporting a wireless capability identifier of a terminal is provided, and this embodiment is exemplified by applying the method to the terminal. In this embodiment, the method includes the steps of:
The access network equipment may include an AMF network element and a base station, and 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 moving to 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 obtains the target location area information from the broadcast message, that is, obtains the location area of the AMF network element where the terminal is located at the moment.
After acquiring the target location area information, the terminal judges whether the wireless capability identification corresponding to the target location area information is stored in the terminal. And if the terminal is determined to store the wireless capability identification corresponding to the target location area information, directly reporting the wireless capability identification 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 method for reporting the terminal wireless capability identifier provided by the embodiment of the application receives broadcast information which is sent by access network equipment and carries target location area information; and when the terminal stores the wireless capability identification corresponding to the target location area information, reporting the stored wireless capability identification to the AMF network element. According to the method, the wireless capability identifications corresponding to different location area information are stored in the terminal, and when the terminal moves to the target location area, the wireless capability identifications corresponding to the target location area are directly reported to the AMF network element. Therefore, when the terminal moves to the area covered by the AMF network element, the process that the access network equipment distributes the wireless capability identification to the terminal is not needed, so that the overhead of the process that the access network equipment distributes the wireless capability identification to the terminal on the network element and the terminal signaling plane can be reduced, and the communication efficiency of the terminal and the access network equipment can be improved. In particular, a wireless capability information query procedure of a 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, and no new signaling needs to be added, so that the practicability of the method for reporting the wireless capability identifier of the terminal can be improved.
In one embodiment, the terminal stores a first correspondence table and a second correspondence table, the first correspondence table stores a correspondence between the AMF information and the location area information, and the second correspondence table stores a correspondence between the AMF information and the wireless capability identifier. Specifically, the AMF information may be an AMF identity (AMF id).
Stored in the first correspondence table may be a one-to-one correspondence between the AMF information and the location area information, that is, one AMF information corresponds to one location area information. The first correspondence table may also store 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 one-to-one correspondence between the AMF information and the wireless capability identifier, that is, one AMF information corresponds to one wireless capability identifier. The second correspondence table may also store many-to-one correspondence between the AMF information and the wireless capability identifier, that is, multiple AMF information corresponds to one wireless capability identifier.
Based on the first mapping table and the second mapping table stored in the terminal, the method for reporting the wireless capability identifier of the terminal further includes:
and inquiring the first corresponding relation table and the second corresponding relation table based on the target location area information, and determining whether the terminal stores a wireless capability identifier corresponding to the target location area information.
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 inquired based on the target location area information so as to determine whether the wireless capability identification corresponding to the target location area information is stored in the terminal. If the terminal inquires the wireless capability identification corresponding to the target position area information in the first corresponding relation table and the second corresponding relation table based on the target position area information, determining that the wireless capability identification corresponding to the target position area information is stored in the terminal; and if the terminal does not inquire the wireless capability identification corresponding to the target position area information in the first corresponding relation table and the second corresponding relation table based on the target position area information, determining that the wireless capability identification corresponding to the target position area information is not 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 corresponding relation table and the second corresponding relation table stored in the terminal, and the method is simple in logic and convenient to implement.
In one embodiment, as shown in fig. 7, one possible implementation related to querying the first corresponding relation table and the second corresponding relation table based on the target location area information includes the steps of:
and step 300, searching a first corresponding relation table based on the target position area information.
If the correspondence between the AMF information and the location area information is stored in the first correspondence table, the terminal queries whether there is AMF information corresponding to the target location area information in the first correspondence table based on the target location area information.
And 310, under the condition that the AMF information corresponding to the target location area information is inquired, inquiring a second corresponding relation table according to the inquired AMF information.
The second correspondence table is a correspondence between the AMF information and the wireless capability identifier. If the terminal inquires the AMF information corresponding to the target location area information in the first corresponding relation table, the terminal inquires whether a 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 inquire the AMF information corresponding to the target location area information in the first correspondence table, it is impossible to inquire the wireless capability identifier corresponding to the AMF information in the second correspondence table, that is, it means that 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 terminal is indicated to store the wireless capability identifier corresponding to the target location area information. And if the terminal does not inquire the wireless capability identification corresponding to the inquired AMF information in the second corresponding relation table, the terminal does not store the wireless capability identification corresponding to the target location area information.
In this embodiment, the terminal stores a first correspondence table of a correspondence between the AMF information and the location area information, and a second correspondence table of a correspondence between the AMF information and the wireless capability identifier. After the terminal acquires the target location area information, the wireless capability identification corresponding to the target location area information can be quickly and accurately determined by inquiring the first corresponding relation table and the second corresponding relation table.
In an optional embodiment, after obtaining the first corresponding relationship table and the second corresponding relationship table, the terminal may determine the corresponding relationship between the location area information and the wireless capability identifier according to the corresponding relationship between the AMF information and the location area information in the first corresponding relationship table and the corresponding relationship between the AMF information and the wireless capability identifier in the second corresponding relationship table, so as to form a third corresponding relationship table.
Based on the third mapping table, the method for reporting the wireless capability identifier of the terminal further includes: and inquiring the third corresponding relation table based on the target location area information to determine whether the terminal stores the wireless capability identification corresponding to the target location area information.
If the terminal can inquire the wireless capability identification corresponding to the target location area information in the third corresponding relation table, the terminal is indicated to store the wireless capability identification corresponding to the target location area information; if the terminal does not inquire the wireless capability identifier corresponding to the target location area information in the third correspondence table, it indicates that the wireless capability identifier corresponding to the target location area information is not stored in the terminal.
In one embodiment, the method for reporting the wireless capability identifier of the terminal further includes:
and determining that the terminal does not store the wireless capability identifier corresponding to the target location area information, initiating a wireless capability identifier acquisition process, and storing the wireless capability identifier and the AMF information acquired based on the wireless capability identifier acquisition process into the first corresponding relation table and the 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 is indicated to move to the area covered by the AMF network element for the first time, and at the moment, the terminal initiates a wireless capability identifier acquisition flow to the access network equipment so as to acquire the wireless capability identifier distributed by the access network equipment for the terminal and the AMF information corresponding to the AMF network element. And after acquiring the wireless capability identifier redistributed by the access network equipment, the terminal stores the wireless capability identifier and the AMF information in the first corresponding relation table and the 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 corresponding relationship table and the second corresponding relationship table. Therefore, when the terminal moves to the area covered by the AMF network element again, the wireless capability identifier can be directly inquired in the first corresponding relation table and the second corresponding relation table, the wireless capability identifier acquisition process does not need to be initiated again, and the overhead brought to the network element and the signaling plane of the terminal can be reduced.
In one embodiment, as shown in fig. 8, a possible implementation manner related to initiating a wireless capability identifier acquisition procedure includes the steps of:
And 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 radio capability information of the terminal and the information of the AMF network element that the terminal has arrived before, etc. The context data of the AMF network element that the terminal has previously arrived at, for example: encryption algorithms and integrity algorithms, 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, receiving a registration receiving message sent by the AMF network element in response to the registration request message, where the registration receiving message includes the radio capability identifier and the AMF information.
After receiving the registration request message, the AMF network element sends the wireless Capability information of the terminal in the registration request message to a 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 wireless capability information of the terminal, and transmit the wireless capability identifier to the AMF network element.
The AMF network element sends a registration receiving message to the terminal through the base station to inform the terminal of successful registration. 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 Kingyu. That is, the terminal receives the radio capability identifier allocated 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, and after receiving the registration request information, the AMF network element directly queries whether there is wireless capability information included in the registration request message.
