Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a and b, a and c, b and c, or a and b and c, wherein a, b and c can be single or multiple. In addition, for the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like do not limit the quantity and execution order. For example, the "first" of the first terminals and the "second" of the second terminals in the embodiment of the present application are only used to distinguish different terminals.

It is noted that, in the present application, words such as "exemplary" or "for example" are used to mean exemplary, illustrative, or descriptive. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the prior art, when the UE reports the capability ID, only one capability ID may be randomly selected for reporting, and the randomly selected capability ID may not meet the filtering parameter of the current base station or the capability required by the current base station, and at this time, the network side will request the capability again. The UE may store filtering parameters or capability parameter sets corresponding to other capability IDs to be in accordance with the filtering parameters of the current base station or capabilities required by the current base station, which may cause the current base station to further request capabilities again according to the filtering parameters actually used by the current base station, thereby bringing about signaling overhead and access delay. And after requesting the capability again, the network side allocates the capability ID to the UE again, but the network side does not know that the capability parameter set corresponding to the filtering parameter at this time has already been allocated the capability ID and the UE stores the capability ID, which will cause that the same capability parameter set corresponding to the same filtering parameter is allocated with a plurality of different capability IDs, occupying redundant storage space. Therefore, the embodiment of the present application provides a communication method, which can reduce signaling overhead and access delay when a UE stores multiple capability IDs allocated by a network.

The embodiment of the application provides a communication method, which is applied to the communication scene shown in fig. 1. As shown in fig. 1, when accessing a network, a terminal device UE may report capability information of the UE itself to a base station device, where the capability information is a set of capability parameters supported by the UE, and after receiving the capability information reported by the UE, the base station device may configure parameters for the UE according to the capability information.

For example, to reduce signaling overhead, when reporting capability information to a base station device, a UE may send a capability identifier ID to a core network device, where the capability ID corresponds to the capability information (a set of capability parameter sets), and the capability ID is used to identify a set of capability parameter sets corresponding to the capability ID. Because the core network device stores the mapping relationship between the capability ID and the capability information, after receiving the capability ID, the core network device can determine the capability information corresponding to the capability ID and send the capability information corresponding to the capability ID to the base station device.

In one implementation, the capability ID may be an ID assigned by a device vendor (Manufacturer-specific). For example, a device manufacturer may pre-configure a capability ID and its corresponding capability information in advance, where the capability ID may be preset in the UE before the UE leaves the factory, and the core network device may also preset a mapping relationship between the capability ID and the capability information. Optionally, the capability information corresponding to the capability ID allocated by the device manufacturer may be all capability information, that is, the capability ID allocated by the device manufacturer may correspond to a full set of capability parameters supported by the UE.

In another implementation, the capability ID may be a network-assigned ID. For example, the network-assigned capability ID may be an ID assigned to the UE by a network device (e.g., a core network device) after the UE enters the network. For example, after the UE reports the capability information to the core network device, the network device may allocate a capability ID for the capability information and store a mapping relationship between the capability ID and the capability information, and after the UE receives the capability ID allocated by the network device, also store the mapping relationship between the capability ID and the capability information. It should be noted that, in this implementation, the capability ID allocated by the Network device may be unique in a PLMN (Public Land Mobile Network) Network, that is, different capability information is allocated with different capability IDs, so that the capability information corresponding to one capability ID is unique.

Fig. 2 is a terminal device provided in this embodiment, where the terminal device may be a chip or a device disposed in the terminal device, which is not limited in this embodiment. As shown in fig. 2, the terminal device 200 includes at least one processor 201, a memory 202, a transceiver 203, and a communication bus 204.

The following describes each constituent element of the communication apparatus in detail with reference to fig. 2:

For example, the processor 201 is a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), or one or more Integrated circuits configured to implement embodiments of the present invention, such as: one or more microprocessors (digital signal processors, DSPs), or one or more Field Programmable Gate Arrays (FPGAs).

The processor 201 may perform various functions of the communication device by running or executing software programs stored in the memory 202, and invoking data stored in the memory 202, among other things.

In particular implementations, processor 201 may include one or more CPUs, such as CPU0 and CPU1 shown in fig. 2, as one embodiment.

In particular implementations, a communication device may include multiple processors, such as processor 201 and processor 205 shown in fig. 2, for example, as an embodiment. Each of these processors may be a single-Core Processor (CPU) or a multi-Core Processor (CPU). A processor herein may refer to one or more communication devices, circuits, and/or processing cores for processing data (e.g., computer program instructions).

The Memory 202 may be a Read-Only Memory (ROM) or other types of static storage communication devices that can store static information and instructions, a Random Access Memory (RAM) or other types of dynamic storage communication devices that can store information and instructions, an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Compact Disc Read-Only Memory (CD-ROM) or other optical Disc storage, optical Disc storage (including Compact Disc, laser Disc, optical Disc, digital versatile Disc, blu-ray Disc, etc.), a disk storage medium or other magnetic storage communication device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited to such. The memory 202 may be self-contained and coupled to the processor 201 via a communication bus 204. The memory 202 may also be integrated with the processor 201.

The memory 202 is used for storing software programs for executing the scheme of the invention, and is controlled by the processor 201 to execute.

A transceiver 203 for communicating with other communication devices. Of course, the transceiver 203 may also be used for communicating with a communication network, such as an ethernet, a Radio Access Network (RAN), a Wireless Local Area Network (WLAN), etc. The transceiver 203 may include a receiving unit to implement a receiving function and a transmitting unit to implement a transmitting function.

The communication bus 204 may be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, an Extended ISA (EISA) bus, or the like. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, only one thick line is shown in FIG. 2, but it is not intended that there be only one bus or one type of bus.

The communication device configuration shown in fig. 2 does not constitute a limitation of the communication device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

In order to solve the problem that the signaling overhead and the access delay of the access network are large when the UE stores a plurality of capability IDs allocated by the network in the prior art, embodiments of the present application provide a communication method, which can reduce the signaling overhead and the access delay of the access network of the UE when the UE stores a plurality of capability IDs allocated by the network.

As shown in fig. 3, a communication method provided in the embodiment of the present application includes steps S301 to S303.

S301, the base station equipment sends filtering information to the UE.

The filtering information is used for determining a first capability ID corresponding to the filtering information. The filtering information is used to instruct the UE to filter capability information of the UE. The filtering information indicates the capability that the base station needs to report by the UE and which information is related, so that the base station configures the UE based on the capability reported by the UE, and the capability information of the UE is a set of capability parameter sets supported by the UE. That is, the filtering information is used to instruct the UE to filter the capability parameter corresponding to the capability required by the base station from all the capability parameters supported by the UE.

Illustratively, the first capability ID corresponds to first capability information of the UE. The first capability information is one set of capability parameters supported by the UE, and the first capability ID is used to identify the one set of capability parameters. In particular, the set of capability parameters may include one or more of the following: packet Data Convergence Protocol (PDCP) capability, Radio Link Control (RLC) capability, Medium Access Control (MAC) capability, Physical layer (PHY) capability, Radio Frequency (RF) capability, measurement correlation capability, and the like. The embodiments of the present application do not limit the specific capabilities included in the capability parameter set, and are only exemplary.

Illustratively, the UE stores one or more capability IDs including a first capability ID corresponding to the filtering information. The one or more capability IDs may be network-assigned IDs or device manufacturer-assigned IDs, which is not limited in this embodiment of the present application. When the UE includes multiple capability IDs, the capability information corresponding to different capability IDs may be the same or different, which is not limited in this embodiment of the present application.

Illustratively, the UE stores a first mapping list, where the first mapping list includes the one or more capability IDs and capability information corresponding to each capability ID. For example, as shown in table 1, the UE stores three capability IDs, which may be denoted as capability ID1, capability ID2, and capability ID3, and capability information corresponding to each capability ID, wherein capability ID1 corresponds to capability information a, capability ID2 corresponds to capability information B, and capability ID3 corresponds to capability information C, and each of capability information a, capability information B, and capability information C is a set of capability parameter sets.

TABLE 1

Capability ID	Capability information
		ID 1	Capability information A
ID 2	Capability information B
		ID 3	Capability information C

In one implementation, the filtering information may include a filtering parameter, and specifically, the filtering parameter may include one or more of the following: a frequency band (band) parameter, a bandwidth parameter, a carrier parameter, and the like, where the frequency band parameter may be one or more frequency bands supported by a base station, the bandwidth parameter may be a maximum bandwidth value supported by the base station, or a maximum uplink bandwidth value supported by the base station, or a maximum downlink bandwidth value supported by the base station, and the carrier parameter may be a maximum uplink carrier value supported by the base station, or a maximum downlink carrier value supported by the base station, and all capability parameters supported by the UE are filtered by sending the filtering parameter supported by the base station to the UE, that is, only a capability ID corresponding to a capability required by the base station is sent.

In an implementation manner, the filtering information may also include a filtering index, where the filtering index corresponds to the filtering parameter. The filter index is used to identify filter parameters. For example, the filtering index 1 corresponds to the filtering parameter 1, the filtering index 2 corresponds to the filtering parameter 2, and the filtering parameters corresponding to different filtering indexes may be different.

For example, the filtering information may be carried in an Access Stratum (AS) message, which may be a unicast message or a broadcast message. For example, the base station may send the first information to one UE through a unicast message, or may send the first information to a plurality of UEs through a broadcast message, which is not limited in this embodiment of the present application.

Optionally, in step S301, before the UE reports the capability ID, the base station device sends filtering information to the UE, so that the UE may determine, according to the filtering information sent by the base station device, a first capability ID corresponding to the filtering information in one or more capability IDs stored in the UE.

S302, the UE sends a first capability ID corresponding to the filtering information to the core network equipment.

For example, the sending, by the UE, the first capability ID corresponding to the filtering information to the core network device includes: and the UE selects a first capability ID corresponding to the filtering information from one or more capability IDs stored in the UE according to the filtering information sent by the base station, and sends the first capability ID to the core network equipment.

For example, when the UE selects the first capability ID corresponding to the filtering information from the one or more capability IDs stored in the UE, the capability ID corresponding to the filtering information is first selected as the first capability ID, specifically, the filtering information corresponding to the capability information corresponding to the first capability ID may be the same as the filtering information sent by the base station to the UE, or the filtering information corresponding to the capability information corresponding to the first capability ID may include the filtering information sent by the base station to the UE, or the filtering information corresponding to the capability information corresponding to the first capability ID may be approximately or partially overlapped with the filtering information sent by the base station to the UE. For example, the filtering information sent by the base station device to the UE is (a, b), and if the filtering information corresponding to the capability information corresponding to the first capability ID is (a, b), it may be considered that the filtering information corresponding to the capability information corresponding to the first capability ID corresponds to the filtering information sent by the base station to the UE; or, if the filtering information corresponding to the capability information corresponding to the first capability ID is (a, b, c), it may also be considered that the filtering information corresponding to the capability information corresponding to the first capability ID corresponds to the filtering information sent by the base station to the UE, where the capability information reported by the UE includes the capability required by the base station; or, if the filtering information corresponding to the capability information corresponding to the first capability ID is (a, c), it may also be considered that the filtering information corresponding to the capability information corresponding to the first capability ID may correspond to the filtering information sent by the base station to the UE, where a portion of the capability information reported by the UE includes capabilities required by the base station, and the base station device may further configure the UE according to whether the capabilities required by the portion are sufficient.

In one implementation, if the filtering information is a filtering parameter. The first mapping list stored in the UE may include one or more capability IDs and capability information corresponding to each capability ID. In this implementation manner, the UE may analyze the filtering parameter corresponding to each piece of capability information according to the plurality of pieces of capability information stored in the first mapping list, and select, according to the filtering parameter sent by the base station, a capability ID corresponding to the filtering parameter sent by the base station in the first mapping list as the first capability ID.

Optionally, the first mapping list stored in the UE may further include a filtering parameter corresponding to each capability ID. In this implementation, the UE may select, according to the filtering parameter sent by the base station device, a capability ID corresponding to the filtering parameter sent by the base station device in the first mapping list, and determine the capability ID as the first capability ID.

In another implementation, if the filtering information is a filtering index. The first mapping list stored in the UE may include one or more capability IDs, capability information corresponding to each capability ID, and a filtering index corresponding to each capability ID. In this implementation, the UE may select, as the first capability ID, the capability ID corresponding to the filtering index sent by the base station in the first mapping list according to the corresponding relationship between the filtering index and the capability ID stored in the first mapping list and according to the filtering index sent by the base station. Optionally, the first mapping list stored in the UE may further include a filtering parameter corresponding to each capability ID.

Illustratively, the UE sends a first capability ID to the core network device, where the first capability ID may be carried in a Non-access stratum (NAS) message and sent from the UE to the core network device. It should be noted that, when the UE sends the NAS message to the core network device, the base station simply forwards the NAS message and cannot analyze the content of the NAS message.

Different from the prior art, the existing UE only sends the capability information corresponding to the filtering parameter after receiving the filtering parameter sent by the base station. In this embodiment, after receiving the filtering information sent by the base station device, the UE may select a first capability ID corresponding to the filtering information from one or more capability IDs stored in the UE, and send the first capability ID to the core network device. Since the UE is in wireless connection with the core network, the UE sends the capability ID to the core network, which reduces the overhead of the UE accessing the network compared to sending the capability information. In addition, in this embodiment, the UE may receive the filtering index sent by the base station, and since the UE and the base station are in wireless connection, the base station sends the filtering index to the UE, which further reduces the overhead of accessing the network by the UE compared with sending the filtering parameter.

It can be understood that, when a plurality of capability IDs are stored in the UE and the plurality of capability IDs include a capability ID corresponding to a filtering parameter of the base station, if a capability ID is randomly reported by using the prior art and the filtering parameter corresponding to the randomly reported capability ID does not necessarily conform to the filtering parameter of the base station, the network side will request the capability from the UE again, which results in a large signaling overhead and a large access delay for the UE to access the network. However, when the UE stores multiple capability IDs, the embodiment may receive the filtering parameter sent by the base station before the UE reports the capability IDs, and send the first capability ID corresponding to the filtering parameter to the core network device, so that the network side does not need to re-allocate the capability IDs to the UE, and signaling overhead and access delay of the UE accessing the network are reduced.

(optional) S303, the core network device sends the first capability ID and/or the first capability information corresponding to the first capability ID to the base station device.

For example, the core network device may send the received first capability ID directly to the base station device. The base station device may store a second mapping list, where the second mapping list includes a plurality of capability IDs and capability information corresponding to each capability ID. After receiving the first capability ID sent by the core network device, the base station device may determine, according to the second mapping list stored in the base station device, first capability information corresponding to the first capability ID.

Illustratively, the core network device stores a third mapping list, where the third mapping list includes a plurality of capability IDs and capability information corresponding to each capability ID. After receiving the first capability ID sent by the UE, the core network device may determine first capability information corresponding to the first capability ID according to a third mapping list stored in the core network device, and send the first capability information to the base station device. Optionally, the third mapping list stored in the core network device may further include a filtering parameter and/or a filtering index corresponding to the capability ID.

For example, the core network device may send the first capability ID and the first capability information corresponding to the first capability ID to the base station device. The specific manner is the same as the above-mentioned manner, and is not described herein again.

It should be noted that, because the connection between the core network device and the base station device is a wired connection, the overhead of the wired connection is not limited, and the connection between the UE and the core network device is a wireless connection, the overhead of the wireless connection is limited, so that the first capability ID may be sent to the core network device by the UE, and then the capability information corresponding to the first capability ID may be sent to the base station device by the core network device, so as to reduce the network overhead between the UE and the core network device.

It can be understood that, in this embodiment, before the UE reports the capability ID, the filtering parameter sent by the base station device is received, the capability ID corresponding to the filtering parameter is selected as the first capability ID from one or more capability IDs stored in the UE according to the filtering parameter, and the first capability ID is sent to the core network device. Compared with the prior art that the UE randomly selects one capability ID for reporting, the embodiment of the application can directly report the capability ID corresponding to the filtering parameter when the UE stores the capability ID corresponding to the filtering parameter of the base station equipment, and does not need the network side to request the capability from the UE again, thereby reducing the signaling overhead and the access delay of the UE accessing the network.

The embodiment of the application provides a communication method, which comprises the steps of sending filtering information to UE through base station equipment; the UE sends a first capability ID corresponding to the filtering information to the core network equipment; the core network device sends the first capability ID and/or first capability information corresponding to the first capability ID to the base station device. According to the embodiment, when the UE stores the capability ID corresponding to the filtering information of the base station equipment, the capability ID corresponding to the filtering information can be directly reported without requiring the network side to request the capability from the UE again, so that the signaling overhead and the access delay of the UE accessing the network are reduced.

As shown in fig. 4, another communication method provided in the embodiment of the present application includes steps S401 to S404.

S402, the core network equipment sends filtering information to the UE.

It can be understood that the filtering information is the same as the filtering information in step S301, and specific reference may be made to the related description in step S301, which is not described herein again.

For example, the filtering information in this step may be carried in a NAS message and sent from the core network device to the UE. It should be noted that, when the core network device sends the NAS message to the UE, the base station simply forwards the NAS message and cannot analyze the content of the NAS message.

Compared with the previous embodiment in which the base station device directly sends the filtering information to the UE, the present embodiment is to send the filtering information to the UE by the core network device. Because the UE reports the first capability ID to the core network device through the NAS message, and also receives the filtering information sent by the core network device through the NAS message, it can be ensured that the influence on the base station device side is minimal, that is, neither reporting of the first capability ID nor receiving of the filtering information requires the base station device to perceive.

S403, the UE sends the first capability ID corresponding to the filtering information to the core network equipment.

It can be understood that the specific implementation manner of the UE sending the first capability ID corresponding to the filtering information to the core network device in step S403 and step S302 is the same, and reference may be specifically made to the description in step S302, which is not described herein again.

(optional) S404, the core network device sends the first capability ID and/or the first capability information corresponding to the first capability ID to the base station device.

It may be understood that, in steps S404 and S303, the core network device sends the first capability ID to the base station device, and/or a specific implementation manner of the first capability information corresponding to the first capability ID is the same, which may specifically refer to the description in step S303 and is not described herein again.

Step S401 is (optionally) further included before step S402 described above.

S401, the base station equipment sends filtering information to the core network equipment.

It can be understood that the filtering information is the same as the filtering information in step S301, and specific reference may be made to the related description in step S301, which is not described herein again. The filtering information in step S401 may be carried in the AS message.

The embodiment of the application provides a communication method, which comprises the steps that filtering information is sent to core network equipment through base station equipment; the core network equipment sends filtering information to the UE; the UE sends a first capability ID corresponding to the filtering information to the core network equipment; the core network device sends the first capability ID and/or first capability information corresponding to the first capability ID to the base station device. According to the embodiment, when the UE stores the capability ID corresponding to the filtering information of the base station equipment, the capability ID corresponding to the filtering information can be directly reported without requiring the network side to request the capability from the UE again, so that the signaling overhead and the access delay of the UE accessing the network are reduced.

As shown in fig. 5, for another communication method provided in this embodiment of the present application, if the filtering information includes the filtering index, before the above steps S301 to S303 and steps S401 to S404, the communication method may further include steps S501 to S503.

S503, the core network equipment sends the filtering index to the UE.

Illustratively, the filtering index sent by the core network to the UE corresponds to the first capability ID allocated by the core network.

For example, the filtering index in step S503 may be carried in a NAS message and sent from the core network device to the UE. It should be noted that, when the core network device sends the NAS message to the UE, the base station simply forwards the NAS message and cannot analyze the content of the NAS message.

For example, the filtering index in step S503 may also be carried in an AS message and sent from the core network device to the UE. It should be noted that, when the core network device sends the AS message to the UE, the base station may forward the AS message and analyze the content of the AS message to obtain the filtering index.

Optionally, in step S503, the core network device may further send the first capability ID corresponding to the filtering index to the UE.

It can be understood that the core network device sends the filtering index and the first capability ID corresponding to the filtering index to the UE, so that the UE may store the corresponding relationship between the filtering index and the first capability ID, and thus in step S302 or step S403, the UE may determine the first capability ID corresponding to the filtering index according to the filtering index sent by the base station device or the core network device. It should be noted that the filtering index and the first capability ID corresponding to the filtering index may be sent to the UE through the same message, or may be sent to the UE through different messages, and it is only necessary to ensure that the UE can determine the corresponding relationship between the filtering index and the first capability message.

Optionally, one or more steps of steps S501-S502 may be further included before step S503.

S501, the base station equipment sends the filtering parameters to the core network equipment.

It can be understood that the filtering parameters are the same as the filtering parameters in step S301, and specific reference may be made to the related description in step S301, which is not described herein again.

S502, the core network equipment sends the filtering index corresponding to the filtering parameter to the base station equipment.

The filtering index is used to identify a corresponding filtering parameter, which may refer to the above description and is not described herein again.

For example, before the core network device allocates the first capability ID corresponding to the filtering parameter of the base station to the UE, the core network device may allocate a filtering index to the filtering parameter sent by the base station, and send the filtering index to the base station, so that the base station device obtains a corresponding relationship between the filtering index and the filtering parameter, and when the base station device performs step S301 again, the base station device may send the filtering index to the UE according to the corresponding relationship between the filtering parameter and the filtering index.

For example, the allocating, by the core network device, the filtering index to the filtering parameter sent by the base station device may include: the core network device may receive the filtering parameters sent by the multiple base station devices, and allocate a filtering index to the same filtering parameter. For example, if the filtering parameter of the base station 1 is a, the filtering parameter of the base station 2 is b, and the filtering parameter of the base station 3 is a, the core network may allocate a filtering index 1 to the filtering parameter a, allocate a filtering index 2 to the filtering parameter b, send the filtering index 1 corresponding to the filtering parameter a to the base stations 1 and 3, and send the filtering index 2 corresponding to the filtering parameter b to the base station 2.

Optionally, in step S502, the core network device may further send a filtering parameter corresponding to the filtering index to the base station device, so that the base station device stores a corresponding relationship between the filtering index and the filtering parameter.

This embodiment provides a communication method, which allocates a filtering index to a filtering parameter through a core network device, and sends the filtering index to a UE. Therefore, the UE can acquire the corresponding relation between the filtering index and the capability ID, so that when the UE receives the filtering index sent by the base station equipment or the core network equipment, the first capability ID corresponding to the filtering index can be determined according to the filtering index, and the signaling overhead and the access delay of the UE for accessing the network are reduced.

As shown in fig. 6, a communication method provided in the embodiment of the present application includes steps S601 to S603.

S601, the base station equipment sends first area information to the UE.

The first area information is used for indicating an area of the terminal device, and the area of the terminal device is an area where the terminal device is located. It can be understood that, if the UE can receive the first area information, the first area information indicates an area indicated by the first area information that the UE enters/is located in, that is, the first area information indicates an area where the UE is located. The area where the terminal device is located may be a tracking area, or an indication area based on a radio access network, or an area covered by a base station device, or an area covered by a cell, which is not limited in this embodiment of the present invention.

For example, the Tracking Area is a Tracking Area, and the UE does not need to initiate a Tracking Area update procedure when moving within the Tracking Area, and the Tracking Area may include one or more base stations or one or more cells. The radio access network-based indication Area is a RAN-based Notification Area, the UE in the RRC _ INACTIVE state may move within the radio access network-based indication Area without notifying the network, and the radio access network-based indication Area may include one or more base stations or one or more cells.

Illustratively, the first area information corresponds to area configuration information, and the area configuration information corresponds to the first capability ID. The first capability ID corresponds to first capability information of the UE. The first capability information is one set of capability parameters supported by the UE, and the first capability ID is used to identify the one set of capability parameters. The description in step S301 may be referred to for the capability parameter set specifically, and is not repeated here. It can be understood that the area configuration information corresponding to the first capability ID may be: the area configuration information indicates an area where the first capability ID can be used, or the area configuration information indicates an area where the first capability ID is preferentially used.

For example, the area configuration information may indicate one or more areas, i.e., the area configuration information may indicate an area list. The first area information corresponding to the area configuration information may be understood as: the area indicated by the first area information is the area indicated by the area configuration information, or the area indicated by the first area information belongs to an area in an area list indicated by the area configuration information.

Illustratively, the area configuration information is used to indicate one or more tracking areas, one or more indication areas based on a radio access network, an area covered by one or more base station devices, or an area covered by one or more cells, which is not limited in this embodiment. For example, the area configuration information 1 is used to indicate tracking areas 1, 2 and 3, i.e., tracking areas 1, 2 and 3 correspond to the area configuration information 1, and the area configuration information 1 may correspond to the capability ID1, i.e., UEs within the area range indicated by the area configuration information 1 may prioritize or use the capability information corresponding to the capability ID 1. If the area (first area information) where the UE is located belongs to the tracking area 1, the first area information corresponds to the area configuration information 1. It should be noted that one or more base stations in the tracking area correspond to the same filtering parameter, or one or more cells in the tracking area correspond to the same filtering parameter, or one or more base stations in the indicated area based on the radio access network correspond to the same filtering parameter, or one or more cells of the base station correspond to the same filtering parameter.

Illustratively, the UE stores one or more capability IDs, where the one or more capability IDs include a first capability ID corresponding to the area configuration information. The one or more capability IDs may be network-assigned IDs or device manufacturer-assigned IDs, which is not limited in this embodiment of the present application. When the UE includes multiple capability IDs, the capability information corresponding to different capability IDs may be the same or different, which is not limited in this embodiment of the present application.

For example, the first mapping table stored in the UE may include a capability ID, capability information corresponding to the capability ID, and area configuration information corresponding to the capability ID. As shown in table 1, the UE stores three capability IDs, which may be denoted as capability ID1, capability ID2, and capability ID3, capability information a corresponding to capability ID1, capability information B corresponding to capability ID2, capability information C corresponding to capability ID3, capability ID1 corresponding to area configuration information X, capability ID2 corresponding to area configuration information Y, and capability ID3 corresponding to area configuration information Z, and area configuration information corresponding to different capability IDs may be different.

TABLE 2

Capability ID	Capability information	Region configuration information
			ID1	Capability information A	Region configuration information X (tracking region 1, tracking region 2, tracking region 3)
ID 2	Capability information B	Region configuration information Y (tracking region 4, tracking region 5)
			ID 3	Capability information C	Zone configuration information Z (tracking zone 6)

For example, the first area information may be carried in an Access Stratum (AS) message, which may be a unicast message or a broadcast message. For example, the base station may send the first area information to one UE through a unicast message, or may send the first area information to a plurality of UEs through a broadcast message, which is not limited in this embodiment of the present application.

Optionally, in step S701, before the UE reports the capability ID, the base station device sends the first area information to the UE, so that the UE may determine the area configuration information according to the first area information sent by the base station device, and determine the first capability ID corresponding to the area configuration information in one or more capability IDs stored in the UE.

S602, the UE sends a first capability ID corresponding to the first area information to the core network equipment.

For example, the sending, by the UE, the first capability ID corresponding to the first area information to the core network device includes: the UE determines area configuration information corresponding to the first area information according to the first area information sent by the base station, selects a first capability ID corresponding to the area configuration information from one or more capability IDs stored in the UE, and sends the first capability ID to core network equipment. For example, the base station broadcasts to the UE that the area where the UE is located is tracking area 1, that is, the first area information is tracking area 1, and the UE may determine, according to the mapping list shown in table 2, that the area configuration information corresponding to tracking area 1 is area configuration information X, then determine that the first capability ID corresponding to the area configuration information is capability ID1, and send the capability ID1 to the core network device.

It can be understood that, when the UE stores multiple capability IDs, the embodiment may receive first area information sent by the base station before the UE reports the capability IDs, determine area configuration information corresponding to the first area information according to the first area information, and send the first capability ID corresponding to the area configuration information to the core network device, so that a network side does not need to request the capability from the UE again, and signaling overhead and access delay of the UE accessing the network are reduced.

(optional) S603, the core network device sends the first capability ID and/or the first capability information corresponding to the first capability ID to the base station device.

Illustratively, the third mapping list stored in the core network device includes a plurality of capability IDs and capability information corresponding to each capability ID. After receiving the first capability ID sent by the UE, the core network device may determine first capability information corresponding to the first capability ID according to a third mapping list stored in the core network device, and send the first capability information to the base station device. Optionally, the third mapping list stored in the core network device may further include area configuration information corresponding to the capability ID.

It can be understood that, in this embodiment, before the UE reports the capability ID, by receiving the first area information sent by the base station device, determining, according to the first area information, area configuration information corresponding to the first area information, and selecting, from one or more capability IDs stored in the UE, the capability ID corresponding to the area configuration information as the first capability ID; and sending the first capability ID to the core network equipment. Therefore, when the terminal accesses the network, the capability ID corresponding to the area configuration information can be used or preferentially used according to the area (first area information) where the terminal is located, so as to reduce the signaling overhead and the access delay of the UE accessing the network.

The embodiment of the application provides a communication method, which comprises the steps of sending first area information to UE through base station equipment; the UE sends a first capability ID corresponding to the area configuration information to the core network equipment; and the core network equipment sends first capability information corresponding to the first capability ID to the base station equipment. According to the embodiment, when the area where the UE is located is in the area range indicated by the area configuration information and the UE stores the first capability ID corresponding to the area configuration information, the capability ID corresponding to the area configuration information is directly reported without requiring the network side to request the capability from the UE again, so that the signaling overhead and the access delay of the UE for accessing the network are reduced.

As shown in fig. 7, for another communication method provided in the embodiment of the present application, the communication method includes steps S701 to S704.

S702, the core network equipment sends first area information to the UE.

It can be understood that the first area information is the same as the first area information in step S601, and reference may be specifically made to the related description in step S601, which is not described herein again.

For example, in this step, the first area information may be carried in a NAS message and sent from the core network device to the UE. It should be noted that, when the core network device sends the NAS message to the UE, the base station simply forwards the NAS message and cannot analyze the content of the NAS message.

Compared with the previous embodiment in which the base station device directly sends the first area information to the UE, the present embodiment is to send the first area information to the UE by the core network device. Because the UE reports the first capability ID to the core network device through the NAS message, and also receives the first area information sent by the core network device through the NAS message, it can be ensured that the influence on the base station device side is minimal, that is, neither reporting of the first capability ID nor receiving of the first area information requires the base station device to perceive.

S703, the UE sends a first capability ID corresponding to the first area information to the core network device.

It can be understood that the specific implementation manner of the UE sending the first capability ID corresponding to the first area information to the core network device in step S703 and step S602 is the same, and reference may be specifically made to the description in step S602, which is not described herein again.

(optional) S704, the core network device sends the first capability ID and/or the first capability information corresponding to the first capability ID to the base station device.

It can be understood that, in steps S704 and S603, the core network device sends the first capability ID to the base station device, and/or a specific implementation manner of the first capability information corresponding to the first capability ID is the same, which may specifically refer to the description in step S603, and is not described herein again.

Step S701 is (optionally) further included before step S702.

S701, the base station equipment sends the first area information to the core network equipment.

It can be understood that the first region information is the same as the first region information in step S601, and reference may be specifically made to the related description in step S701, which is not described herein again. The first area information in step S701 may be carried in the AS message.

The embodiment of the application provides a communication method, which comprises the steps that first area information is sent to core network equipment through base station equipment; the core network equipment sends first area information to the UE; the UE sends a first capability ID corresponding to the area configuration information to the core network equipment; the core network device sends the first capability ID and/or first capability information corresponding to the first capability ID to the base station device. According to the embodiment, when the area where the UE is located is in the area range indicated by the area configuration information and the UE stores the first capability ID corresponding to the area configuration information, the capability ID corresponding to the area configuration information is directly reported without requiring the network side to request the capability from the UE again, so that the signaling overhead and the access delay of the UE for accessing the network are reduced.

As shown in fig. 8, for another communication method provided in the embodiment of the present application, before the above steps S601 and S701, the communication method may further include one or more steps of steps S801a/S801 b-S802.

S802, the core network equipment sends the area configuration information to the UE.

Illustratively, the area configuration information sent by the core network to the UE corresponds to the first capability ID allocated by the core network. The area configuration information is the same as the area configuration information in step S601, and reference may be specifically made to the related description in step S601, which is not described herein again.

For example, the area configuration information in step S802 may be carried in a NAS message and sent from the core network device to the UE. It should be noted that, when the core network device sends the NAS message to the UE, the base station simply forwards the NAS message and cannot analyze the content of the NAS message.

For example, the area configuration information in step S802 may also be carried in an AS message and sent from the core network device to the UE. It should be noted that, when the core network device sends the AS message to the UE, the base station may forward the AS message and analyze the content of the AS message to obtain the filtering index.

Optionally, in step S802, the core network device may further send a first capability ID corresponding to the area configuration information to the UE, where the first capability ID is a capability ID allocated by the core network device for the area configuration information, that is, the first capability ID corresponds to the area configuration information.

Optionally, as shown in (a) of fig. 8, a step S801a may be further included before the step S802.

S801a, the base station device sends the filtering parameter to the core network device.

Optionally, in step S801a, the base station device may further send the first area information to the core network device. It can be understood that the first area information is the same as the first area information in step S601, and reference may be specifically made to the related description in step S601, which is not described herein again.

It can be understood that the core network device may allocate, according to a plurality of filtering parameters sent by a plurality of base stations, one piece of area configuration information to the same filtering parameter, where the filtering parameters corresponding to areas in the area list indicated by the area configuration information are the same, that is, an area in the area list indicated by the area configuration information may use or preferentially use the capability ID corresponding to the area configuration information. For example, if the filtering parameter of the base station 1 is a, the first area information is the tracking area 1, the filtering parameter of the base station 2 is b, the first area information is the tracking area 2, the filtering parameter of the base station 3 is a, and the first area information is the tracking area 3, the core network may configure the tracking areas 1 and 3 corresponding to the base station 1 and the base station 3 with the same filtering parameter as one area configuration information 1, and configure the tracking area 2 corresponding to the base station 2 as the area configuration information 2. That is, the filtering parameters corresponding to the regions in the region list included in one region configuration information are the same, and the same capability ID may be bound. Thus, when the first area information of the UE in step S601 is tracking area 1, the tracking area 1 belongs to an area in the list of area configuration information 1, the first area information corresponds to area configuration information 1, and the UE can use or preferentially use the capability ID corresponding to area configuration information 1.

Optionally, as shown in (b) of fig. 8, a step S801b may be further included before the step S802.

S801b, the base station device sends the area configuration information to the core network device.

It can be understood that the area configuration information is the same as the area configuration information in step S601, and reference may be specifically made to the related description in step S601, which is not described herein again.

It is to be understood that the area configuration information may be area configuration information preconfigured in the base station device. For example, when a filtering parameter of the base station device is preconfigured, the area configuration information corresponding to the filtering parameter is configured. The filtering parameters corresponding to the areas in the area list indicated by the area configuration information are the same, that is, the areas in the area list indicated by the area configuration information may use or preferentially use the capability ID corresponding to the area configuration information. For example, the filtering parameter of the base station 1 is a and configured as the area configuration information 1, the filtering parameter of the base station 2 is b and configured as the area configuration information 2, and the filtering parameter of the base station 3 is a and configured as the area configuration information 1.

For example, when the base station device requests the UE for capability using the filtering parameter, the capability information reported by the UE is obtained, the base station device sends the capability information corresponding to the filtering parameter to the core network device, and sends the corresponding area configuration information to the core network device, the core network device receives the capability information and then allocates the capability ID to the capability information, and at the same time, the capability ID corresponds to the area configuration information sent by the base station device. For example, the base station device obtains capability information corresponding to the filtering parameter a, the base station device sends the capability information 1 corresponding to the filtering parameter a and the corresponding area configuration information 1 to the core network device, the core network device allocates the capability ID1 to the capability information 1, and at the same time, the capability ID1 corresponds to the area configuration information, and the core network sends the area configuration information 1 to the UE through step S802, or may also send the first capability ID1 corresponding to the area configuration information 1 to the UE.

The embodiment provides a communication method, which includes sending a filtering parameter to a core network device through a base station device; and the core network equipment sends the area configuration information to the UE. Therefore, the UE can acquire the corresponding relation between the capability configuration information and the capability ID, so that when the UE receives the first area information sent by the base station equipment or the core network equipment, the UE can determine the corresponding area configuration information according to the first area information, further determine the first capability ID corresponding to the area configuration information, and reduce the signaling overhead and the access delay of the UE for accessing the network.

As shown in fig. 9, for yet another communication method provided in the embodiment of the present application, the communication method may further include steps S901 to S903.

S901, the base station equipment sends first information to the UE.

The first information is used for determining a first capability ID corresponding to the first information. The first capability ID corresponds to first capability information. The first capability ID is one of one or more capability IDs stored by the UE.

For example, the first information may be a filtering parameter, a filtering index, or first area information in the foregoing embodiment, and for the related description of the filtering parameter, the filtering index, or the first area information, reference may be made to the foregoing embodiment, which is not described herein again. The content specifically included in the first information is not limited in the embodiments of the present application, and is only an exemplary description here.

For example, the sending, by the base station device, the first information to the UE may include: the base station equipment sends a capability request message to the UE, wherein the capability request message comprises first information.

Illustratively, the capability request message may be carried in an AS message. The AS message may be a unicast message or a broadcast message, which is not limited in this embodiment of the present application.

S902, the UE sends a first capability ID corresponding to the first information to the base station equipment.

For example, the UE sending the first capability ID corresponding to the first information to the base station device includes: the UE selects a first capability ID corresponding to the first information from one or more capability IDs stored in the UE according to the first information sent by the base station, and sends the first capability ID to the base station equipment.

Illustratively, the UE sends the first capability ID corresponding to the first information to the base station device, including: the UE sends a terminal device capability information message to the base station, wherein the terminal device capability information message comprises a first capability ID. That is, the UE may transmit the first capability ID through the terminal device capability information message. The terminal device capability information message may be an AS message.

Optionally, the terminal device capability information message may further include first capability information corresponding to the first capability ID. Therefore, whether the base station equipment stores the first capability information corresponding to the first capability ID or not, the capability parameter supported by the terminal can be obtained directly through the first capability information sent by the UE.

Step S903 may also be included after (optional) step S902.

S903, the base station device sends a first capability ID corresponding to the first information to the core network device.

For example, the purpose of sending the first capability ID to the core network device by the base station device is that after receiving the capability ID sent by the base station, the core network device does not need to allocate the capability ID corresponding to the first information to the UE.

Optionally, in step S903, the base station device may further send first capability information corresponding to the first capability ID to the core network device.

The embodiment of the application provides a communication method, which comprises the steps of sending first information to UE through base station equipment; the UE sends a first capability ID corresponding to the first information to the base station equipment; and the base station equipment sends a first capability ID corresponding to the first information to the core network equipment. Therefore, after receiving the first information sent by the base station equipment, the UE can select a first capability ID corresponding to the first information from one or more capability IDs stored in the UE, and send the first capability ID to the base station equipment. Compared with the prior art that the UE does not report the capability ID, the embodiment of the application can directly report the first capability ID when the UE stores the first capability ID corresponding to the first information sent by the base station equipment, and does not need to redistribute the capability ID on the network side, thereby ensuring that the same group of capability parameter sets of the UE does not correspond to a plurality of capability IDs.

As shown in fig. 10, for yet another communication method provided in the embodiment of the present application, the communication method may further include steps S1001 to S1002.

S1001, the UE sends a first capability ID to the core network equipment.

The first capability ID corresponds to first capability information of the terminal device. The terminal device stores one or more capability IDs, and the first capability ID is the capability ID with the highest priority in the one or more capability IDs stored in the terminal device.

For example, the priority of the capability ID may be sorted according to how much the capability information content corresponding to the capability ID is, where the capability information content is full capability information or partial capability information, the full capability information includes all capability parameters supported by the terminal device, and the partial capability information includes a part of all capability parameters supported by the terminal device. The more the capability information content corresponding to the capability ID, the higher the priority thereof.

Illustratively, the priority of the capability ID corresponding to all the capability information is the highest. If one or more capability IDs stored by the terminal device include a capability ID allocated by a device manufacturer, the capability ID allocated by the device manufacturer is a capability ID with the highest priority, and the capability information corresponding to the capability ID includes all capability parameters supported by the terminal. If one or more capability IDs stored by the terminal device include a capability ID allocated by the network, and the capability information corresponding to the capability ID allocated by the network includes all capability parameters supported by the terminal, the capability ID allocated by the network is the capability ID with the highest priority.

For example, the first capability ID may be a capability identifier corresponding to all capability information.

It can be understood that the content of the capability information is partial capability information, the partial capability information is partial capability information corresponding to the filtering parameter, and the filtering parameter is used for indicating the terminal device to filter the capability information of the terminal device. I.e. the larger the range comprised by the filtering parameter, the more the capability information content. I.e. the more capability information content, the more likely it is to include the filtering parameters of the base station.

For example, since the first capability ID is the capability ID with the largest capability information content corresponding to one or more capability IDs stored by the terminal, the terminal sends the first capability ID to the core network device, and compared with randomly reporting one capability ID in the prior art, the possibility that the capability information content corresponding to the capability ID with the highest priority includes the filtering information of the base station is greatly improved, and compared with the prior art, the signaling overhead and the access delay of the UE accessing the network can be reduced.

(optional) S1002, the core network device sends the first capability ID and/or first capability information corresponding to the first capability ID to the base station device.

It can be understood that, in steps S1002 and S303, the core network device sends the first capability ID to the base station device, and/or a specific implementation manner of the first capability information corresponding to the first capability ID is the same, which may specifically refer to the description in step S303 and is not described herein again.

The application provides a communication method, which comprises the steps that a first capability ID is sent to core network equipment through UE; the core network device sends the first capability ID and/or first capability information corresponding to the first capability ID to the base station device. In this embodiment, the UE reports the first capability ID with the highest priority among the one or more capability IDs stored in the UE to the core network device, and compared with the prior art in which the UE reports the capability ID to the network side randomly, the possibility that the capability information content corresponding to the capability ID with the highest priority corresponds to the filtering information of the base station is higher, and the signaling overhead and the access delay of the UE accessing the network can be reduced.

As shown in fig. 11, for yet another communication method provided in the embodiment of the present application, the communication method may further include steps S1101-S1102.

S1101, the UE sends one or more capability IDs to the core network equipment.

The one or more capability IDs are all or a portion of the one or more capability IDs stored by the UE.

Illustratively, the UE sends one or more capability IDs to the core network device, and the one or more capability IDs may be carried in a NAS message sent from the UE to the core network device. It should be noted that, when the UE sends the NAS message to the core network device, the UE first sends the NAS message to the base station, and then the base station forwards the NAS message to the core network device.

Optionally, in step S1101, the UE may further send the filtering parameter corresponding to the capability identifier to the core network device. For example, the UE may also send the filtering parameter corresponding to each capability identifier to the core network device.

S1102, the core network device sends the first capability ID and/or first capability information corresponding to the first capability ID to the base station device.

Illustratively, the one or more capability IDs include the first capability ID. The first capability ID includes a capability ID corresponding to the filtering parameter of the base station device, and the first capability ID may be one or more capability IDs.

Illustratively, the first capability ID is a capability ID corresponding to the filtering parameter of the base station device. In step S1102, the sending, by the core network device, the first capability ID to the base station device may include: the core network device may select, from the one or more capability IDs sent by the UE, a capability ID corresponding to the filtering parameter of the base station device as the first capability ID.

For example, the core network device may determine corresponding first capability information according to the first capability ID, and send the first capability information to the base station device.

For example, the core network device may send the first capability ID and the first capability information to the base station device.

Illustratively, the core network device stores a third mapping list, where the third mapping list includes a capability ID and capability information corresponding to the capability ID. The core network device may analyze the filtering parameter corresponding to each capability ID according to the capability information corresponding to each capability ID, and search the first capability ID corresponding to the filtering parameter of the base station device in the third mapping list.

Optionally, the third mapping list may further include a filtering parameter corresponding to the capability ID. At this time, the core network device may search for the first capability ID corresponding to the filtering parameter of the base station device according to the third mapping list.

It may be understood that the filtering parameter of the base station device may be stored in the third mapping list in the core network device, or the filtering parameter of the base station device sent by the base station device may be received before step S1102, which is not limited in this embodiment of the present invention.

Illustratively, the first capability ID is a plurality of capability IDs and includes a capability ID corresponding to the filtering parameter of the base station device. In step S1102, the sending, by the core network device, the first capability ID to the base station device may include: the core network device retransmits the one or more capability IDs received from the terminal device to the base station device. It will be appreciated that the core network simply forwards one or more capability IDs directly to the base station without any processing of the capability IDs.

For example, the base station device may determine, according to the filtering parameters corresponding to the plurality of first capability IDs, a capability ID corresponding to the filtering parameters of the base station device, or determine capability information corresponding to the capability ID corresponding to the filtering parameters of the base station device.

It can be understood that, after determining the first capability ID, the base station device may configure the UE according to the first capability information corresponding to the first capability ID.

It should be noted that, in this scheme, the UE may send the plurality of capability IDs stored in the UE to the core network device, and the core network device may select the capability ID corresponding to the filtering parameter of the base station device from the plurality of capability IDs, or send the plurality of capability IDs to the base station device, so that when the capability ID corresponding to the filtering parameter of the base station device is stored in the UE, the network side does not need to request the UE for capability again, thereby reducing signaling overhead and access delay of the UE accessing the network.

The embodiment of the application provides a communication method, which comprises the steps that one or more capability IDs are sent to core network equipment through UE; the core network device sends the first capability ID, or the first capability information corresponding to the first capability ID, or both the first capability ID and the first capability information to the base station device. According to the embodiment, when the capability ID corresponding to the filtering parameter of the base station equipment is stored in the UE, the network side does not need to request the capability from the UE again, and the signaling overhead and the access delay of the UE accessing the network are reduced.

As shown in fig. 12, for another communication method provided in the embodiment of the present application, the communication method may further include steps S1201-S1205.

S1201, the base station equipment sends first indication information to the UE.

The first indication information is used for indicating the UE to send all capability information supported by the UE to the base station equipment. The full capability information includes full capability parameters supported by the UE.

For example, the sending, by the base station device, the first indication information to the UE may include: the base station equipment sends a capability request message to the terminal equipment, wherein the capability request message comprises first indication information.

For example, the capability request message may be an AS message, and the AS message may be a unicast message or a broadcast message. For example, the base station may send the first indication information to one UE through a unicast message, or may send the first indication information to a plurality of UEs through a broadcast message, which is not limited in this embodiment of the present application.

S1202, the UE transmits all capability information to the base station device.

Illustratively, the UE sends all capability information to the base station device, including: and the UE sends a terminal equipment capability information message to the base station equipment, wherein the terminal equipment capability information message comprises all capability information. The terminal device capability information message may be an AS message.

(optional) S1203, the base station device sends all capability information to the core network device.

For example, the purpose of sending the total capability information to the core network device by the base station device is that the core network device allocates a capability ID to the total capability information.

(optional) S1204, the core network device sends the capability ID corresponding to all the capability information to the UE.

Illustratively, the capability ID is a capability ID corresponding to the entire capability information allocated by the core network device to the UE.

Optionally, step S1205 is further included before step S1201.

And S1205, the core network equipment sends second indication information to the base station equipment.

The second indication information is used for indicating the base station equipment to request all the capability information supported by the terminal equipment from the terminal equipment.

It can be understood that, in this embodiment, the UE may receive the indication message sent by the base station, and report all the capability information, where the all the capability information is all the capability parameters supported by the UE, and the base station may configure the UE according to the all the capability information.
