detailed description

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. In this application, "at least one" refers to one or more, and "multiple" refers to two or more. "And/or" describes the association relationship of the associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A alone exists, both A and B exist, and B exists alone, where A, B can be singular or plural. The character "/" generally indicates that the associated objects are in an "or" relationship. "The following at least one item (a)" or similar expressions refers to any combination of these items, including any combination of a single item (a) or plural items (a). For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or, a and b and c, where a, b and c c can be single or multiple. In addition, in order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same items or similar items that have substantially the same function and effect. Those skilled in the art can understand that words such as "first" and "second" do not limit the number and execution order. For example, the "first" in the first terminal and the "second" in the second terminal in the embodiment of the present application are only used to distinguish different terminals.

It should be noted that in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

In the prior art, when the UE reports the capability ID, only one capability ID can be randomly selected to report, and the randomly selected capability ID may not meet the filtering parameters of the current base station or the capabilities required by the current base station. At this time, the network side will request the capability again. . And the UE may save the filtering parameters or capability parameter sets corresponding to other capability IDs to meet the filtering parameters of the current base station or the capabilities required by the current base station. This will cause the current base station to re-request capabilities based on the filtering parameters actually used by itself. Incoming signaling overhead and access delay. Moreover, after the capability is requested again, the network side allocates a capability ID to the UE again, but the network side does not know that the capability parameter set corresponding to the filtering parameter has been assigned the capability ID and the UE saves the capability ID, which will cause the same filtering parameter to correspond The same ability parameter set is assigned multiple different ability IDs, occupying excess storage space. To this end, the embodiments of the present application provide a communication method that can reduce the signaling overhead and access delay for the UE to access the network when the UE saves multiple capability IDs allocated by the network.

The embodiment of the present application provides a communication method, which is applied to the communication scenario shown in FIG. 1. As shown in Figure 1, when a terminal device UE accesses the network, it can report its own capability information to the base station device. This capability information is a set of capability parameters supported by the UE. After the base station device receives the capability information reported by the UE, it can report the capability The information is UE configuration parameters.

Exemplarily, in order to reduce signaling overhead, when the UE reports capability information to the base station device, it may send a capability identification ID to the core network device. The capability ID corresponds to capability information (a set of capability parameters), and the capability ID is used for Identify its corresponding set of capability parameters. Since the core network device saves the mapping relationship between the capability ID and the capability information, the core network device can determine the capability information corresponding to the capability ID after receiving 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 manufacturer-specific. Exemplarily, the equipment manufacturer may pre-configure the capability ID and its corresponding capability information in advance. The capability ID may be preset in the UE before the UE leaves the factory, and the core network equipment may also preset the capability ID and capability information. Mapping relations. Optionally, the capability information corresponding to the capability ID assigned by the equipment manufacturer may be all capability information, that is, the capability ID assigned by the equipment manufacturer may correspond to the complete set of capability parameters supported by the UE.

In another implementation manner, the capability ID may be an ID allocated by the network. Exemplarily, the capability ID allocated by the network may be an ID allocated to the UE by a network device (for example, 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 can allocate a capability ID for the capability information and save the mapping relationship between the capability ID and the capability information. After the UE receives the capability ID allocated by the network device, it also saves the capability ID Mapping relationship with capability information. It should be noted that, in this implementation, the capability ID assigned by the network device can be unique under one operator (Public Land Mobile Network, PLMN) network, that is, different capability information is assigned different capability IDs, so one capability The capability information corresponding to the ID is unique.

In order to solve the problem of large signaling overhead and access delay of accessing the network when the UE saves multiple capability IDs allocated by the network in the prior art, an embodiment of the present application provides a communication method that can save the network in the UE. When multiple capability IDs are allocated, the signaling overhead and access delay for the UE to access the network are reduced.

As shown in FIG. 3, a communication method provided by an embodiment of this application, the communication method includes step S301-step S303.

S301. The base station device sends filtering information to the UE.

The filtering information is used to determine the first capability ID corresponding to the filtering information. The filtering information is used to indicate the UE's ability to filter the UE. The filtering information indicates which information the base station needs to report from the UE is related to the information so that the base station can configure the UE based on the capability reported by the UE. The UE capability information is a set of capability parameters supported by the UE. That is, the filtering information is used to instruct the UE to filter the capability parameters corresponding to the capabilities required by the base station among all capability parameters supported by the UE.

Exemplarily, the first capability ID corresponds to the first capability information of the UE. The first capability information is a capability parameter set supported by the UE, and the first capability ID is used to identify the capability parameter set. Specifically, the capability parameter set may include one or more of the following: Packet Data Convergence Protocol (PDCP) capability, Radio Link Control Protocol (RLC) capability, Media Access Control (Medium Access Control, MAC) capabilities, physical layer (Physical, PHY) capabilities, radio frequency (RF) capabilities, measurement-related capabilities, etc. The embodiment of the present application does not limit the specific capabilities included in the capability parameter set, and is only an exemplary description here.

Exemplarily, a first mapping list is stored in the UE, and the first mapping list includes the foregoing one or more capability IDs and capability information corresponding to each capability ID. For example, as shown in Chart 1, the UE stores three capability IDs and capability information corresponding to each capability ID. The three capability IDs can be recorded as capability ID1, capability ID2, and capability ID3, where capability ID1 corresponds to capability information A , Capability ID2 corresponds to capability information B, and capability ID3 corresponds to capability information C. The capability information A, capability information B, and capability information C are respectively a set of capability parameters.

Table 1

能力IDAbility ID	能力信息Capability information
ID 1ID 1	能力信息AAbility information A
ID 2ID 2	能力信息BAbility information B
ID 3ID 3	能力信息CCapability information C

In an implementation manner, the above-mentioned filtering information may include filtering parameters. Specifically, the filtering parameters may include one or more of the following: band parameters, bandwidth parameters, carrier parameters, etc. The frequency band parameters may be supported by the base station. One or more frequency bands, the bandwidth parameter may be the maximum bandwidth value supported by the base station, or the maximum uplink bandwidth value supported by the base station, or the maximum downlink bandwidth value supported by the base station, and the carrier parameter may be the maximum uplink carrier value supported by the base station, or The maximum carrier value supported by the base station or the maximum downlink carrier value supported by the base station is filtered by sending the filtering parameters supported by the base station to the UE to filter all the capability parameters supported by the UE, that is, only the capability ID corresponding to the capability required by the base station is sent.

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

Exemplarily, the foregoing filtering information may be carried in an access stratum (Access Stratum, AS) message, and the access stratum message 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 multiple UEs through a broadcast message, which is not limited in this embodiment of the application.

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

S302: The UE sends the first capability ID corresponding to the filtering information to the core network device.

Exemplarily, the UE sending the first capability ID corresponding to the filtering information to the core network device includes: according to the filtering information sent by the base station, the UE selects the first capability ID corresponding to the filtering information from one or more capability IDs stored by the UE, and Send the first capability ID to the core network device.

Exemplarily, when the UE selects the first capability ID corresponding to the filtering information from one or more stored capability IDs, it first selects the capability ID corresponding to the filtering information as the first capability ID, specifically, the first capability ID corresponds to The filtering information corresponding to the capability information 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 first capability ID The filtering information corresponding to the capability information may be similar or partially overlapping with the filtering information sent by the base station to the UE. For example, the filtering information sent by the base station equipment to the UE is (a, b). If the filtering information corresponding to the capability information corresponding to the first capability ID is (a, b), it can be considered that the capability information corresponding to the first capability ID corresponds to The filtering information 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 can also be considered that the capability information corresponding to the first capability ID corresponds to The filtering information corresponds to the filtering information sent by the base station to the UE. At this time, the capability information reported by the UE includes the capabilities required by the base station; or, if the filtering information corresponding to the capability information corresponding to the first capability ID is (a, c), then also It can be considered that the filtering information corresponding to the capability information corresponding to the first capability ID can correspond to the filtering information sent by the base station to the UE. At this time, the capability information reported by the UE includes the capabilities required by the base station, and the base station equipment can further base on the capabilities required by this part. Is it sufficient to configure the UE.

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 can analyze the filtering parameters corresponding to each capability information according to the multiple capability information stored in the first mapping list, and then select the filtering parameters sent by the base station in the first mapping list according to the filtering parameters sent by the base station. The capability ID corresponding to the parameter is the first capability ID.

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

In another implementation manner, 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 the capability ID corresponding to the filter index sent by the base station in the first mapping list according to the corresponding relationship between the filter index and the capability ID stored in the first mapping list, and then according to the filter index sent by the base station Is the first capability ID. Optionally, the first mapping list stored in the UE may also include filtering parameters corresponding to each capability ID.

Exemplarily, the UE sends a first capability ID to the core network device, and the first capability ID may be carried in a non-access stratum (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 only forwards the NAS message and cannot parse the content of the NAS message.

Different from the prior art, after receiving the filtering parameter sent by the base station, the existing UE only sends the capability information corresponding to the filtering parameter. In this embodiment, after receiving the filtering information sent by the base station device, the UE may select the 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 there is a wireless connection between the UE and the core network, compared with sending the capability information, the UE sending the capability ID to the core network reduces the overhead for the UE to access the network. Moreover, in this embodiment, the UE can receive the filter index sent by the base station. Since the UE and the base station are wirelessly connected, the base station sends the filter index to the UE. Compared with sending the filter parameters, the UE access network overhead is further reduced. .

It is understandable that if multiple capability IDs are stored in the UE, and the multiple capability IDs include the capability ID corresponding to the filtering parameter of the base station, if a capability ID is randomly reported by the prior art, the randomly reported capability The filtering parameter corresponding to the ID does not necessarily conform to the filtering parameter of the base station, so the network side will re-request the capability from the UE, resulting in a large signaling overhead and access delay for the UE to access the network. However, in this embodiment, when the UE stores multiple capability IDs, before the UE reports the capability ID, the filtering parameter sent by the base station can be received, and the first capability ID corresponding to the filtering parameter can be sent to the core network device, thereby eliminating the need for the network side Then re-allocate the capability ID for the UE, reducing the signaling overhead and access delay for the UE to access the network.

(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.

Exemplarily, the core network device may directly send the received first capability ID to the base station device. A second mapping list may be stored in the base station device, and the second mapping list includes multiple capability IDs and capability information corresponding to each capability ID.

For example, area configuration information 1 is used to indicate tracking area 1, tracking area 2, and tracking area 3. That is, tracking areas 1, 2, and 3 correspond to area configuration information 1. This area configuration information 1 can correspond to capability ID 1, that is, in area configuration information The UE within the area indicated by 1 can give priority or use the capability information corresponding to the capability ID1. If the area where the UE is located (first area information) belongs to tracking area 1, then the first area information corresponds to 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 the indication area based on the wireless access network One or more base stations in the base station correspond to the same filtering parameters, or one or more cells in the indication area based on the radio access network correspond to the same filtering parameters, or one or more cells in the base station correspond to the same filtering parameters.

As shown in Figure 1, the UE stores three capability IDs, capability information corresponding to each capability ID, and area configuration information corresponding to each capability ID. The three capability IDs can be recorded as capability ID1, capability ID2, and capability ID3. , Where capability ID1 corresponds to capability information A, capability ID2 corresponds to capability information B, capability ID3 corresponds to capability information C, capability ID1 corresponds to area configuration information X, capability ID2 corresponds to area configuration information Y, capability ID3 corresponds to area configuration information Z, different capabilities The area configuration information corresponding to the ID can be different.

The UE may first determine that the area configuration information corresponding to tracking area 1 is area configuration information X according to the mapping list shown in Table 2. And then confirm 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 is understandable that when multiple capability IDs can be stored in the UE in this embodiment, the first area information sent by the base station may be received before the UE reports the capability ID, and the corresponding area configuration information is determined according to the first area information. The first capability ID corresponding to the area configuration information is sent to the core network device, so that the network side does not need to request the capability from the UE again, and the signaling overhead and access delay for the UE to access the network are reduced.

The area in the area list indicated by the area configuration information corresponds to the same filtering parameter, that is, the area configuration The area in the area list indicated by the information can use or preferentially use the capability ID corresponding to the area configuration information.

For example, when the base station equipment uses the filtering parameters to request capabilities from the UE and obtains the capability information reported by the UE, the base station equipment sends the capability information corresponding to the filtering parameters to the core network equipment and at the same time sends the corresponding area configuration information to the core network equipment. After receiving the capability information, the network device allocates a 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.
