To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner to facilitate understanding.

In order to make the description of the following embodiments clear and concise, first a brief introduction of related concepts or technologies is given:

Terminal devices include devices that provide users with voice and/or data connectivity. For example, they may include handheld devices with a wireless connection function or processing devices connected to a wireless modem. The terminal device can communicate with the core network via a radio access network (RAN), and exchange voice and/or data with the RAN. The terminal equipment may include user equipment (UE), wireless terminal equipment, mobile terminal equipment, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile station), mobile station (mobile), remote Station (remote station), access point (access point, AP), remote terminal equipment (remote terminal), access terminal equipment (access terminal), user terminal equipment (user terminal), user agent (user agent), or user Equipment (user device), etc. For example, it may include mobile phones (or "cellular" phones), computers with mobile terminal devices, portable, pocket-sized, handheld, computer-built or vehicle-mounted devices, smart wearable devices, and so on. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants, PDA), and other equipment. It also includes restricted devices, such as devices with low power consumption, or devices with limited storage capabilities, or devices with limited computing capabilities. Examples include barcodes, radio frequency identification (RFID), sensors, global positioning system (GPS), laser scanners and other information sensing equipment. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device. For the convenience and conciseness of the description, the terminal device in the following description uses UE as an example.

Access network equipment corresponds to different equipment in different systems. For example, in the second generation (2G) communication system, the RAN device may include a base station and a base station controller; in the third generation (3G) communication system, the RAN device may include a base station and a radio network controller (radio network controller). controller, RNC); includes the evolved base station (NodeB or eNB or e-NodeB, evolutional NodeB) in the long term evolution (LTE) system or the long term evolution-advanced (LTE-A); Or it can also include the next generation node B (gNB) in the new radio (NR) system of the fifth generation (5G) mobile communication technology, or it can also include the cloud access network ( Centralized unit (CU) and distributed unit (DU) in cloud radio access network (Cloud RAN) system. In future evolution or emerging systems, new network-side devices can be corresponded, which is not limited in the embodiment of the present application. For the sake of simplicity, the following description of the access network equipment takes the base station as an example.

Core Network (CN) devices correspond to different devices in different systems. For example, in 3G, it can correspond to the service support node (serving GPRS support node, SGSN) of general packet radio service technology (general packet radio service, GPRS) and/or the gateway support node (gateway GPRS Support Node, GGSN) of GPRS; In the 4th generation (4G), it can correspond to mobility management entity (MME) and/or serving gateway (S-GW); in 5G, it can correspond to Access and Mobility Management Function (AMF), Session Management Function (SMF) or User plane Function (UPF).

Optionally, the functions implemented by the core network device or the access network device in the embodiments of the present application may be implemented by one network element, or jointly implemented by multiple network elements, or by one or more of one network element. The functional module is implemented, which is not specifically limited in the embodiment of the present application. It is understandable that the above functions may be network elements in hardware devices, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (for example, a cloud platform).

Capability information of the terminal device: The capability information of the terminal device is used to indicate the capability of the terminal device, and the capability of the terminal device can be understood as the function supported by the terminal device. In other words, the capability information of the terminal device can determine the functions that the terminal device can support, such as the list of frequencies supported by the terminal device, whether the terminal device supports carrier aggregation (CA), and what type of CA is the terminal device’s Power level, security algorithm supported by terminal equipment, etc. In addition, in 5G NR, terminal equipment also has a multi-radio access technology (radio access technology, RAT) capability, that is, the ability of the terminal equipment to work in multiple RATs at the same time. Multi-RAT capabilities include EN-DC and NE- DC etc., for example, EN-DC is a way that LTE and NR work together as DC and LTE is the master node, that is, a terminal device is connected to the LTE base station and the NR base station at the same time, and the two base stations provide services at the same time. Multi-RAT capability is also requested as a RAT type during capability request.

Exemplarily, the following takes the terminal equipment as the UE and the communication system as 5G NR and LTE as an example to briefly introduce the capability structure of the terminal equipment:

(1) UE capabilities in 5G NR: 5G NR UE capabilities may include bandwidth information and feature set combination information supported by the UE in NR. The UE capabilities of 5G NR may also include other radio frequency capabilities, physical capabilities, and measurement capabilities.

(2) UE capabilities in LTE: UE capabilities in LTE may include band combination (BC) and feature set information supported by the UE in LTE. The UE capability structure of LTE may also include other radio frequency capabilities, physical capabilities, measurement capabilities and other capabilities.

Network equipment needs to allocate appropriate resources and algorithms according to the capabilities of the terminal equipment. For example, in the case of UE, the base station needs to allocate corresponding frequency resources to it according to the frequency list supported by the UE. The base station needs to determine whether the terminal equipment supports CA or not. Configure secondary cells for terminal equipment, and so on. This requires that the capabilities of the terminal equipment can be reported in some way. Among them, the network device can request the terminal device to report the capability, and in some cases the terminal device will also actively report the capability.

In a possible implementation manner, in order to reduce the size of the capability report when the network device makes a capability request to the terminal device, it will adopt a filtered report manner. Exemplarily, taking the base station as an example, the base station may indicate the required range of the capability information of the terminal device through the capability indication information. For example, the capability indication information may include frequency band information, bandwidth information, and carrier information of the terminal equipment required by the base station. In a possible implementation manner, the capability indication information may be, for example, a capability filtering parameter. Taking a 5G system as an example, the capability filtering parameter may specifically be a capability request filter (capability request filter), and the capability request filter may include a frequency list (freq band list) and sounding reference signal (sounding reference signal, SRS) carrier switching (SRS carrier switching), freq band list is used to indicate the frequency list that the terminal device can support, SRS carrier switching is used to indicate whether the terminal device supports SRS carrier switching .

In a possible implementation, the base station may carry capability indication information in the capability request message. The capability request message may be, for example, a UE capability enquiry. After the base station receives the capability request message from the base station, it will The carried capability indication information selects the capability required by the base station for reporting.

Exemplarily, the following is an example of a UE capability query request message, where Sequence is an array set, maxRAT-CapabilityContainers is the number of RATs simultaneously requested in the current capability query message, and a capability query request message includes at least one for a single RAT capability request (UE-CapabilityRAT-Request), each capability request for a single RAT includes RAT type and freq band list, where RAT type is used to indicate the requested RAT type, freq band list is used to indicate network device request List of frequency bands. In the example, each freq band list also includes carrier quantity information and carrier bandwidth information.

Because the capacity information of terminal equipment is too large, the storage and transmission consumption of the capacity in the wireless transmission process is relatively large, and even exceeds the capacity of wireless transmission. Therefore, the wireless standard introduces the ability to report based on the capability identity (capability ID) method. A capability identifier can be used to identify a specific set of capabilities. For example, the first capability identifier may be used to identify the "first capability set" of the terminal device, and the second capability identifier may be used to identify the "second capability set" of the terminal device, and the capabilities of the terminal device corresponding to the first capability set and the second capability set The scope of information may be different. For example, the first capability set may include complete capability information of the terminal device (that is, the first capability set includes the complete set of capability information of the terminal device), and the second capability set may include part of the capability information of the terminal device.

At present, there are two types of capability identifiers. The first one is that the manufacturer assigns identifiers in advance and presets them inside the terminal equipment. In possible scenarios, the network equipment also presets the mapping relationship between the identifier and the capability set. In this case, it can generally be considered that the identifier assigned by the device manufacturer corresponds to the complete set of capability information of the terminal device. The other is that after the terminal device accesses the network, the network device assigns the identifier. In this scenario, the terminal device first reports the capability set once. After the network device assigns the identifier and saves the mapping relationship between the identifier and the capability set, the terminal device only The corresponding identification needs to be reported, and the reporting capability set is no longer required. The network device needs to ensure that the allocated identification is unique under a public land mobile network (PLMN) and will not appear for multiple different capability sets When the same capability identifier is assigned.

In order to facilitate the understanding of the following embodiments of the present application, the network architecture applied by the embodiments of the present application will be described below. It should be noted that the network architecture described in the embodiments of this application is to illustrate the technical solutions of the embodiments of this application more clearly, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that With the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

As shown in FIG. 1, a communication system 10 provided by an embodiment of this application, the communication system 10 includes a terminal device 101 and an access network device 102 to which the terminal device 101 accesses. The terminal device 101 and the access network device 102 may directly communicate with each other, and may also communicate through the forwarding of other devices, which is not specifically limited in the embodiment of the present application.

In an optional implementation manner, the terminal device 101 is configured to determine a second capability set of the terminal device 101 according to the capability indication information from the access network device 102, and the second capability set corresponds to the capability of the access network device 102 Instruction information, the capability instruction information is used to indicate the range of capability information required by the access network device 102; the terminal device 101 is also used to send first instruction information to the access network device 102, and the first instruction information is used to indicate the first instruction information A capability set is the same as the second capability set, or the first indication information is used to indicate the difference between the first capability set and the second capability set. The first capability set corresponds to the first capability identifier, and the first capability identifier is configured by the equipment vendor. The access network device 102 is configured to receive the first instruction information from the terminal device 101, and determine the second capability set according to the first instruction information and the first capability set. Furthermore, the access network device 102 is further configured to determine the second capability identifier corresponding to the second capability set, and send the second capability identifier to the terminal device 101.

Because in the embodiment of the present application, the terminal device 101 can determine the second capability set of the terminal device 101 according to the capability indication information from the access network device 102, and send the first indication information to the access network device 102, the first indication The information may indicate that the second capability set is the same as the first capability set, or the first indication information may indicate the difference between the second capability set and the first capability set. Further, for example, when the first capability set and the second capability set are the same, the first indication information may indicate that the second capability set contracts the first capability set. When the first capability set is a subset of the second capability set, that is, in addition to the capability information included in the first capability set, the second capability set also includes some capability information. In this case, the first indication information may indicate the second capability The set also includes this part of capability information. For example, the first capability set includes parameters A, B, and C, the second capability set includes parameters A, B, C, and D, and the first indication information may indicate that the second capability set also includes parameter D. When the second capability set is a subset of the first capability set, that is, the capability information included in the second capability set is part of the capability information in the first capability set, and the first indication information may indicate that the second capability set does not include Some capability information in the first capability set. For example, when the first capability set includes the parameters A, B, and C, and the second capability set includes the parameters A and B, the first indication information may indicate that the second capability set does not include the parameter C. When there is an intersection between the second capability set and the first capability set and the intersection is neither the first capability set nor the second capability set, that is, the second capability set and the first capability set include the same capability information part, then the first indication The information may indicate that part of the capability information in the second capability set is the same as the first capability set, and the second capability set also includes other capability information. For example, the first capability set includes parameters A, B, and C, the second capability set includes parameters B, C, and D, the first indication information may indicate that the second capability set includes parameters B and C, and the second capability set also includes parameters D.

The first indication information enables the access network device 102 to determine the second capability set according to the first indication information and the first capability set.
