Description

Method and device for sending and receiving communication capacity of terminal

Technical Field

The present application relates to the field of information technology, and in particular, to a method and an apparatus for transmitting and receiving communication capability of a terminal.

Background

Currently, the technology is directed to the fifth generation mobile communication technology (the 5)^thgeneration, 5G) New Radio (NR)Two major networking modes, namely independent networking (SA) and non-independent Networking (NSA), are defined. The independent networking mode of the 5G NR requires deployment of an end-to-end all-new network of the 5G system, including a new access network (e.g., nrgbb) and a new generation core (next generation core), and the 5G system independently carries a complete control-plane (CP) and a user-plane (UP), so that the 5G system can operate without depending on a Long Term Evolution (LTE) system and independently provides communication services for users. In the non-independent networking mode, the 5G system needs to rely on the existing LTE system, that is, the NR system and the LTE system need to cooperate with each other to work, for example, a multi-RAT dual connectivity (MR-DC) mode is adopted, and the NR base station and the LTE base station are simultaneously connected with a user to provide a communication service for the user together. In the LTE system, the access network part may be referred to as evolved universal mobile telecommunications system terrestrial radio access (E-UTRA), i.e. a mobile communication radio network in LTE, and the E-UTRA may be regarded as an air interface technology of LTE to some extent.

Specifically, the independent networking mode may include a networking mode: (1) the terminal equipment accesses the E-UTRA base station and the E-UTRA base station is connected with a fourth generation mobile communication technology (the 4)^thgeneration, 4G) core network (abbreviation: LTE independent networking mode), (2) the terminal device accesses the enhanced E-UTRA base station and the enhanced E-UTRA base station is connected to a 5G core network (short for: an eLTE independent networking mode), (3) the terminal equipment is accessed to the NR base station, and the NR base station is connected with a 5G core network (short for: NR independent networking approach). In addition, the non-independent networking mode (the terminal device accesses the E-UTRA base station and the NR base station at the same time) may include a networking mode: (1) the E-UTRA base station is a main base station, the NR base station is a secondary base station, the E-UTRA base station is connected with a 4G core network (short for E-UTRA-NR dual connectivity (EN-DC) networking mode), (2) the E-UTRA base station is a main base station, the NR base station is a secondary base station, the E-UTRA base station is connected with a 5G core network (short for next generation E-UTRA-NR dual connectivity, NGEN-DC) networking mode), (3) the NR base station is a main base station, the E-UTRA base station is a secondary base station, and the NR base station is connected with a 5G core network (short for:NR-E-UTRA dual connectivity (NE-DC) networking).

At present, a terminal device may support one or more networking modes of the above six networking modes, and the terminal device needs to report related communication capability information to a base station according to the supported networking modes, so that the base station can reasonably schedule the terminal device. At present, a terminal device reports communication capability information in a manner of reporting a communication capability message, but in an LTE system and an NR system, the size of one message is limited, for example, in the LTE system, a Packet Data Convergence Protocol (PDCP) data packet maximally includes 8188 bytes, and in the NR system, the PDCP data packet maximally includes 9000 bytes. If the number of bytes of the communication capability message reported by the terminal equipment exceeds the size limit, the terminal equipment cannot successfully send the communication capability message to the base station, and cannot establish communication with the base station, so that communication failure is caused.

Having described some concepts related to embodiments of the present application, a background of embodiments of the present application is described below and is described in detail below with reference to fig. 1.

Fig. 1 is a schematic flow chart of a terminal device transmitting communication capability information, which may be wireless access communication capability information of the terminal device, to a network device in the prior art, and steps of fig. 1 include S11 and S12, which are described in detail below. It should be noted that, the steps described in fig. 1 mainly refer to a signaling flow between the terminal device and the network device, and omit a signaling flow between the network device and the core network.

S11: the network device sends a UE communication capability request message to the terminal device, and the terminal device receives the UE communication capability request message from the network device, where the UE communication capability request message is used to request the terminal device to send communication capability information of the terminal device in a certain Radio Access Technology (RAT).

For example, the UE communication capability request message is a UE communication capability query (UE capability query) message. The UE communication capability request message may indicate one or more RATs (e.g., one or more of E-UTRA technology, NR technology, E-UTRA-NR) and indicate that communication capability information of the terminal device under the RAT is requested.

For a terminal device in a connected state, when the core network device needs the communication capability information of the terminal device and the core network device does not store the communication capability information of the terminal device, the core network device may trigger the network device to initiate a UE communication capability request process, that is, initiate a flow shown in fig. 1 to request the communication capability information of the terminal device. After the network device initiates a request, the terminal device sends the communication capability information of the terminal device to the network device, and the network device further sends the communication capability information of the terminal device to the core network device, so that the network device or the core network device configures or schedules the terminal device according to the communication capability of the terminal device. In different communication systems, the core network device referred to herein may correspond to different devices, for example, in a 4G system, the core network device referred to herein may be a Mobility Management Entity (MME), and in a 5G NR system, the core network device referred to herein may be an access and mobility management function (AMF).

S12: and the terminal equipment sends the UE communication capability message to the network equipment, and the network equipment receives the UE communication capability message from the terminal equipment.

The UE communication capability message carries radio access communication capability information of the terminal device, for example, a certain RAT(s) is included in a UE communication capability request message sent by the network device, if the terminal device supports the RAT(s), the terminal device needs to include a communication capability container (container) of the RAT(s) in the UE communication capability message, the container of the RAT(s) includes the communication capability information of the RAT(s), and the RAT type parameter in the container is set to the RAT. For example: the communication capability information of the E-UTRA technology is requested in the UE communication capability request message, if the terminal equipment supports the E-UTRA technology, the terminal equipment needs to include the communication capability information of the E-UTRA technology in the UE communication capability message, and the RAT type parameter in the UE communication capability message is set as E-UTRA.

The UE communication capability message is implemented by, for example, a UE communication capability information (UE capability information) message, and may be a message dedicated to reporting communication capability information of a terminal device, and the UE communication capability message may include communication capability information of at least one RAT of the terminal device. The wireless access communication capability information of the terminal device may include, for example: PDCP parameters, physical layer parameters, radio frequency parameters, measurement parameters, and the like, where the communication capability parameters specifically correspond to communication capability information such as a frequency band combination (band combination), a supported carrier aggregation bandwidth class (ca-bandwidth class), a modulation and coding scheme (modulation and coding scheme), and the like. The communication capability parameter or the communication capability information is an exemplary communication capability parameter or communication capability information, and in this embodiment, detailed and complete communication capability information is not described herein again.

After receiving the UE communication capability message, the network device may configure PDCP configuration, physical layer configuration, radio frequency configuration, measurement configuration, and the like of the terminal device according to specific parameters of the radio access communication capability information, so as to ensure that the configuration of the terminal device can meet the communication capability of the terminal device itself, that is, the terminal device can normally operate under the configuration of the network device.

As described in the flow shown in fig. 1, the network device sends a UE communication capability request message to the terminal device, requesting the communication capability information of one or more RATs of the terminal device, and the terminal device needs to report the communication capability information of the one or more RATs of the terminal device in the UE communication capability message. When the terminal device sends the communication capability information of the terminal device to a network device (e.g., a base station), the terminal device places the communication capability information in a corresponding communication capability (capability) field according to the RAT in the UE communication capability request message, for example, the terminal device places the communication capability information of the terminal device in the E-UTRA in the UE-EUTRA-capability field, places the communication capability information in the NR in the UE-NR-capability field included in the UE communication capability request message, places the communication capability information in the MR-DC in the UE-MRDC-capability field included in the UE communication capability request message, and then sends the communication capability information including the communication capability field to the network device.

Specifically, each communication capability field is included in each communication capability container (capability container) field, for example, the terminal device places the communication capability information of the terminal device under E-UTRA in the uecapabilitytrat-container field, and the RAT type parameter of the uecapabilitytrat-container is set to E-UTRA. The terminal device will put the communication capability information of the terminal device under NR in the uecapabilitytrat-container field, and the RAT type parameter of the uecapabilitytrat-container is set to NR. The terminal device will put the communication capability information of the terminal device under MR-DC in the uecapabilitytrat-container field, and the RAT type parameter of the uecapabilitytrat-container is set to MR-DC. The communication capability container fields are combined into a communication capability container list (capability container list) field, that is, the communication capability container list field includes a communication capability container (capability container) field of each RAT, and the final communication capability container list field is included in a communication capability information field (UE capability information-IE) for the terminal to report communication capability and is reported to the base station through a UE communication capability message (UE capability information).

The signaling design of the communication capability field is shown in table 1, and the UE-EUTRA-capability field is exemplarily illustrated in table 1.

The signaling design of the communication capability container field is shown in table 2.

TABLE 3

The signaling design of the communication capability information field is shown in table 4, and is exemplarily illustrated in table 1 with a plurality of versions of the communication capability information field.

Specifically, the communication capability field indicates communication capability of a certain RAT, the communication capability container field indicates communication capability of a certain RAT and a type of RAT, the communication capability container list field indicates communication capability of multiple RATs and is formed by combining the communication capability container fields of multiple RATs, the communication capability container list field is included in the communication capability information field, and the communication capability information field is sent to the network device through a communication capability message.

The relationship between the fields is shown in table 5, and the communication capability information field may include a communication capability container list field, a communication capability container field, and a communication capability field; the communication capability container list field may include a communication capability container field, a communication capability field, but may not include a communication capability information field; the communication capability container field may include a communication capability field but cannot include a communication capability container list field and a communication capability information field.

Currently, the independent networking mode includes several specific modes, which are an LTE independent networking mode, and an NR independent networking mode, where the LTE independent networking mode refers to a networking mode in which a terminal device accesses an E-UTRA base station and the E-UTRA base station is connected to a 4G core network, the LTE independent networking mode refers to a networking mode in which the terminal device accesses an enhanced E-UTRA base station and the enhanced E-UTRA base station is connected to a 5G core network, and the NR independent networking mode refers to a networking mode in which the terminal device accesses an NR base station and the NR base station is connected to a 5G core network. The non-independent networking mode also includes several specific modes, which are an EN-DC networking mode, an NGEN-DC networking mode, and an NE-DC networking mode, where the EN-DC networking mode refers to fig. 2D, which means that the E-UTRA base station is a main base station, the NR base station is an auxiliary base station, and the E-UTRA base station is connected to the networking mode of the 4G core network, and the NGEN-DC networking mode refers to fig. 2E, which means that the E-UTRA base station is a main base station, the NR base station is an auxiliary base station, and the E-UTRA base station is connected to the networking mode of the 5G core network, and the NE-DC networking mode refers to fig. 2F, which means that the NR base station is a main base station, the E-UTRA base station is an auxiliary base station, and the NR base station is connected to the networking mode of the 5G core network.

There may be a class of terminal devices, which may support multiple of the above six networking modes, and the terminal device needs to report the relevant capability information to the base station according to the supported networking mode. For example, the terminal device may report the capability information of the terminal device to the network device through the UE capability message in S12, where the UE capability message includes three parts: E-UTRA capability information (carried in UE-EUTRA-capability field), NR capability information (carried in UE-NR-capability field), and MR-DC capability information (carried in UE-MRDC-capability field), if the number of bytes of the capability message reported by the terminal device exceeds the upper limit, the terminal device cannot successfully send the capability message to the network device, and thus communication failure may be caused.

In view of this, in the embodiment of the present application, the terminal device may split the capability information of the terminal device, and load the split plurality of capability information in different messages respectively, and then send the messages to the network device, where the size of each split message is smaller than the upper limit value, so that the network device can successfully receive the capability message.

And S42, the terminal equipment determines N pieces of communication capacity information according to the first message.

Wherein the N pieces of communication capability information constitute total communication capability information of K RATs of the terminal device.

And S44, the network equipment determines the communication capability information of the terminal according to the received K messages.

That is, the network device combines N communication capability information in the K messages into total communication capability information of the terminal.

In S41, the first message sent by the network device to the terminal device may be implemented by a UE communication capability request (e.g., UE capability acquisition) message in the procedure shown in fig. 1. In S43, the K messages sent by the terminal device to the network device may be implemented by K UE communication capability messages (e.g., UE capability information) in the flow shown in fig. 1.

In step S42, the specific content of each of the N pieces of communication capability information is determined according to the field split by the terminal device, and includes but is not limited to the following different implementations:

in a first possible implementation manner, the terminal device splits the communication capability container field of the K RATs of the terminal device into the N pieces of capability information, where one piece of capability information in the N pieces of communication capability information includes part or all of the capability container field, and the capability container field indicates capability information of any one RAT in the K RATs of the terminal device.

For example, a first message sent by the network device is used to request communication capability information of the E-UTRA technology, the NR technology, and the MR-DC technology, and according to the first message, the terminal device places the communication capability information of the terminal device under the E-UTRA in a uecapabilitytrat-container field of the E-UTRA type, then sends a second message carrying the uecapabilitytrat-container field to the network device, then the terminal device places the communication capability information under the NR in a uecapabilitytrat-container field of the NR type, and sends a third message carrying the uecapabilitytrat-container field to the network device, and finally the terminal device places the communication capability information under the MR-DC in a uecapabilitytrat-container field of the MR-DC type, and sends a fourth message carrying the uecapabilitytrat-container field to the network device.

For another example, the first message sent by the network device is used to request communication capability information of the E-UTRA technology, the NR technology, and the MR-DC technology, and according to the first message, the terminal device places the communication capability information of the terminal device under the E-UTRA in a uecapabilitytrat-container field of the E-UTRA type, then splits the uecapabilitytrat-container field into first communication capability information and second communication capability information, sends a second message carrying the first communication capability information to the network device, and sends a third message carrying the second communication capability information to the network device. Further, the terminal device places the communication capability information under NR in a uecapabilitytrat-container field of NR type, then splits the uecapabilitytrat-container field into third communication capability information and fourth communication capability information, and sends a fourth message carrying the third communication capability information to the network device, and sends a fifth message carrying the fourth communication capability information to the network device. Further, the terminal device places the communication capability information under MR-DC in the uecapabilitytrat-container field of MR-DC type, then splits the uecapabilitytrat-container field into fifth communication capability information and sixth communication capability information, and transmits a sixth message carrying the fifth communication capability information to the network device and a seventh message carrying the sixth communication capability information to the network device.

It should be noted that, in the embodiment of the present application, the number of communication capability information specifically included in each of the K messages sent by the terminal device to the network device is not limited, and a second message of the K messages may include one piece of communication capability information, a third message of the K messages includes two pieces of communication capability information, and even a fourth message of the K messages includes a part of one piece of communication capability information. Assuming that the protocol specifies that the number of bytes of a message sent by the terminal to the network device is 100 bytes, if the terminal device splits the uecapabilitytrat-container field of the E-UTRA type into first communication capability information and second communication capability information, the first communication capability information being 10 bytes, the second communication capability information being 10 bytes, in addition, the terminal device splits the NR type uecapabilitytrat-container segment into third communication capability information and fourth communication capability information, the third communication capability information being 90 bytes, the fourth communication capability information being 90 bytes, in this way, the terminal device can carry the first communication capability information and the third communication capability information in the second message, and then sending the second message to the network equipment, then, the terminal equipment loads the second communication capability information and the fourth communication capability information in a third message, and then, sends the third message to the network equipment. In other words, the embodiment of the present application does not limit the permutation and combination manner of the N pieces of communication capability information in the K pieces of messages.

In a second possible implementation manner, the terminal device splits the communication capability field of the K RATs of the terminal device into the N pieces of communication capability information, where one piece of capability information of the N pieces of communication capability information includes part or all of the communication capability field, and the communication capability field indicates the communication capability information of any one RAT of the K RATs of the terminal device.

For example, a first message sent by the network device is used for requesting communication capability information of the E-UTRA technology, the NR technology and the MR-DC technology, and according to the first message, the terminal device places the communication capability information of the terminal device under the E-UTRA in a UE-EUTRA-capability field, then sends a second message carrying the UE-EUTRA-capability field to the network device, then the terminal device places the communication capability information under the NR in a UE-NR-capability field, and sends a third message carrying the UE-NR-capability field to the network device, and finally the terminal device places the communication capability information under the MR-DC in a UE-MRDC-capability field, and sends a fourth message carrying the UE-MRDC-capability field to the network device.

For another example, the first message sent by the network device is used to request communication capability information of the E-UTRA technology, the NR technology, and the MR-DC technology, and the terminal device may put the communication capability information of the terminal device under the E-UTRA in the UE-EUTRA-capability field according to the first message, split the UE-EUTRA-capability field into the first communication capability information and the second communication capability information, send the second message carrying the first communication capability information to the network device, and send the third message carrying the second communication capability information to the network device. Further, the terminal device places the communication capability information under the NR in a UE-NR-capability field, then splits the UE-NR-capability field into third communication capability information and fourth communication capability information, sends a fourth message carrying the third communication capability information to the network device, and sends a fifth message carrying the fourth communication capability information to the network device. Further, the terminal device places the communication capability information under the MR-DC in the UE-MRDC-capability field, then splits the UE-MR-DC-capability field into fifth communication capability information and sixth communication capability information, and sends a sixth message carrying the fifth communication capability information to the network device, and sends a seventh message carrying the sixth communication capability information to the network device.

In a third possible implementation manner, the terminal device splits the communication container list of the K RATs of the terminal device into the N pieces of communication capability information, where one piece of capability information in the N pieces of communication capability information includes a part of a communication capability container list field, and the communication capability container list field indicates total communication capability information of the K RATs of the terminal device.

For example, a first message sent by the network device is used to request communication capability information of the E-UTRA technology, the NR technology, and the MR-DC technology, the terminal device splits the communication capability information under E-UTRA, the communication capability information under NR, and the communication capability information under MR-DC in a communication capability container list (UE-capability RAT-container list or capability container list) field according to the first message, then the terminal device splits the communication capability container list field into N pieces of communication capability information, the terminal device may send each piece of communication capability information to the network device in one message, may send each piece of communication capability information to the network device in two pieces of communication capability information in one message, may send a part of a piece of RAT communication capability information to the network device in one message, and send another part of the RAT communication capability information to the network device in another message The embodiments of the present application are not limited to the specific combination.

In a fourth possible implementation manner, the terminal device splits the communication capability information field of the K RATs of the terminal device into the N pieces of communication capability information, where one piece of capability information of the N pieces of communication capability information includes a part of the communication capability information field, and the communication capability information field indicates total communication capability information of the K RATs of the terminal device.

For example, the first message sent by the network device is used to request communication capability information of the E-UTRA technology, the NR technology, and the MR-DC technology, the terminal device may put communication capability information of the terminal device under the E-UTRA, communication capability information under the NR, and communication capability information under the MR-DC in a communication capability information field (UECapabilityInformation-IE) according to the first message, and then the terminal device splits the communication capability information field into N pieces of communication capability information, and the terminal device may send each piece of communication capability information to the network device in one message, or send every two pieces of communication capability information to the network device in one message, which is not limited in the embodiments of the present application.

In a fifth possible implementation manner, the terminal device splits the communication capability message of the terminal device into K messages according to bytes, where one piece of communication capability information is a part of the communication capability message, and the communication capability message indicates the total communication capability information of the K RATs.

For example, the first message sent by the network device is used to request communication capability information of the E-UTRA technology, the NR technology, and the MR-DC technology, the terminal device may put the communication capability information of the terminal device under the E-UTRA, the communication capability information under the NR, and the communication capability information under the MR-DC technology in a communication capability message (UECapabilityInformation) according to the first message, and then the terminal device splits the information in the communication capability message into N pieces of communication capability information, and the terminal device may send each piece of communication capability information to the network device in one message, or send every two pieces of communication capability information to the network device in one message.

It should be noted that which of the above five implementations the N pieces of communication capability information adopt may be specified by a protocol, or may be configured in advance by the network device, or may be determined by the terminal device itself and notified to the network device. In addition, besides the above five implementation manners, the N pieces of communication capability information may also be implemented by splitting other fields, and the embodiment of the present application is not limited.

In one possible design, when the terminal device determines that the size of the total communication capability information of the terminal device exceeds the upper limit value, the total communication capability information is split into N pieces of communication capability information. That is, when the terminal device determines that the total communication capability information is too large, if the total communication capability information is placed in a message and exceeds the upper limit value, the terminal device splits the total communication capability information to obtain N pieces of communication capability information.
