Detailed ways

The network architecture and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do 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 network With the evolution of 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, it is a schematic diagram of a network architecture to which the embodiments of this application are applicable, including a terminal device and a network device. The terminal device communicates with the network device through a wireless interface.

Terminal device (terminal device) is a device with wireless transceiver function. It can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; it can also be deployed on the water (such as ships, etc.); it can also be deployed in the air ( For example, airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, an industrial control (industrial control) Wireless terminals in ), wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grid, and wireless terminals in transportation safety , Wireless terminals in smart cities, wireless terminals in smart homes, user equipment (UE), etc.

Network equipment is a device that provides wireless communication functions for terminal equipment. Network equipment includes, but is not limited to: the next generation base station (gnodeB, gNB) in the fifth generation (5G), and evolved node B (evolved). node B, eNB), radio network controller (RNC), node B (node B, NB), base station controller (BSC), base transceiver station (BTS), home A base station (for example, home evolved nodeB, or home node B, HNB), baseband unit (BBU), transmission point (transmitting and receiving point, TRP), transmission point (TP), mobile switching center, etc.

When 5G is deployed independently, the logical system of network equipment can adopt a centralized unit (CU) and distributed unit (DU) separation mode. Based on the configuration of the protocol stack function, the CU-DU logic system can be divided into two types, namely the CU-DU separation architecture and the CU-DU fusion architecture. For the CU-DU separation architecture, the functions of the protocol stack can be dynamically configured and divided, some of which are implemented in the CU, and the remaining functions are implemented in the DU. In order to meet the needs of different segmentation options, it is necessary to support ideal transmission networks and non-ideal transmission networks. The interface between CU and DU should follow the 3rd generation partnership project (3rd generation partnership project, 3GPP) specification requirements. Aiming at the CU-DU converged architecture, the logical functions of CU and DU are integrated in the same network device to realize all the functions of the protocol stack.

After the terminal device accesses a certain network, it needs to report the wireless access capability of the terminal device to the network device and the core network. The capability of a terminal device may report the wireless access capability of the terminal device through a capability message (such as UECapabilityInformation), and the capability message may include the capability of the terminal device under one or more radio access technologies (Radio Access Technology, RAT). Among them, wireless access technologies include but are not limited to: New radio (NR) technology, Evolved-UMTS Terrestrial Radio Access (E-UTRA) technology, E-UTRA-NR Technology, NR-E-UTRA technology, UMTS Terrestrial Radio Access (UTRA) technology.

As shown in FIG. 2, it is a schematic flowchart of a method for reporting wireless access capabilities in the prior art. The method includes the following steps:

Step 201: The network device sends a capability request message to the terminal device. Correspondingly, the terminal device can receive the capability request message.

The capability request message is used to request the wireless access capability of the terminal equipment in a certain or certain radio access technologies, for example: E-UTRA technology, UTRA technology, NR technology, one or more of E-UTRA-NR technology Kind of RAT. The capability request message may be a UECapabilityEnquiry message.

As an example, if the network device is an NR base station (ie, gNB), the capability request message will be used to request the terminal device's wireless access capability in the NR technology. Further, it is also possible to simultaneously request wireless access capabilities under E-UTRA technology, E-UTRA-NR technology and other technologies from the terminal equipment.

Generally, the capability request message may also carry filtering information (filter), and the filtering information is used to filter the wireless access capability of the terminal device. Or it can be understood that the terminal device only needs to report to the network device those wireless access capabilities that match the filtering information among the wireless access capabilities supported by the terminal device. The filtering information may include, but is not limited to, one or more of the following: E-UTRA or NR band information, E-UTRA downlink carrier aggregation bandwidth classification (ca-BandwidthClassDL), E-UTRA uplink carrier aggregation Bandwidth classification (ca-BandwidthClassUL), NR's maximum downlink aggregate bandwidth, NR's uplink maximum aggregate bandwidth, NR's maximum downlink carrier number/number of serving cells, NR's maximum uplink carrier number/number of serving cells.

Generally speaking, the filtering information specifically indicates which capability parameters are based on the deployment of the network device, for example, the frequency band supported by the network device will be considered. The network device can request the terminal device for the capability parameters that the network device really needs, and filter Drop some capacity parameters that are not needed under the network device. By sending filtering information, some capability information that is not needed by network devices can be filtered out, and the size of capability messages reported by terminal devices can be reduced, thereby reducing signaling overhead.

Step 202: The terminal device sends a capability message to the network device. Correspondingly, the network device can receive the capability message.

The capability message is used to send the wireless access capability of the terminal device requested by the network device. The capability message may be a UECapability message.

Specifically, if the capability request message does not carry the filtering parameter, the terminal device sends all the wireless access capabilities of the terminal device under all supported wireless access technologies to the network device.

If the capability request message carries the filtering parameter, the terminal device filters out part of the wireless access capabilities from the wireless access capabilities supported by the terminal device based on the filtering parameters and sends it to the network device.

Take the frequency band information in the filtering information as an example.

Example 1: In a single link scenario, the primary serving cell configured by the network device for the terminal device (that is, the primary cell serving the terminal device) works in band1, and the carrier on which the primary cell works is called the primary carrier. In order to increase the transmission bandwidth and increase the uplink and downlink transmission rate, the network equipment can also configure one or more secondary carriers for the terminal equipment to form carrier aggregation. Among them, the cell corresponding to the secondary carrier is called the secondary cell. For example, the secondary cell can work in band2 or band3. For example, the network device is currently working in NR technology, and the capability request message sent by the network device is used to request the terminal device's wireless access capability in the NR technology, and the capability request message carries filtering information, which includes band1 information, For band2 information and band3 information, the wireless access capabilities reported by the terminal equipment to the network equipment include at least:

1) The wireless access capability of terminal equipment corresponding to band1 under NR technology;

2) The wireless access capability of terminal equipment corresponding to band2 under NR technology;

3) The wireless access capability of terminal equipment corresponding to band3 under NR technology;

4) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2) under the NR technology;

5) The wireless access capability of the terminal equipment corresponding to the combination (band2, band3) under the NR technology;

6) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band3) under the NR technology.

Among them, the wireless access capabilities of 1), 2), and 3) above may also be referred to as a single frequency band, or as a wireless access capability under a single carrier. The radio access capabilities of 4), 5), and 6) above can also be referred to as frequency band combination, or radio access capabilities under carrier aggregation.

It should be noted that the above example shows that the terminal device also supports band1, band2, and band3, so the wireless access capabilities corresponding to band1, band2, and band3 are reported. If the terminal device only supports some bands of band1, band2, and band3, the terminal device will only report the wireless access capabilities corresponding to the supported partial bands. Considering that the terminal equipment may be handed over, that is, it is handed over from the original base station to the new base station. Therefore, the terminal equipment can not only report the radio access capability under the single frequency band (or called single carrier) corresponding to the primary serving cell, that is, not only report one support The wireless access capability under the single frequency band (or called single carrier) can also report the wireless access capability under the single frequency band (or single carrier) corresponding to other cells, so that the new base station can refer to the single frequency band (or single carrier) of the terminal equipment. The wireless access capability under the so-called single carrier is reconfigured for terminal equipment.

Example 2: In a dual link scenario, the primary serving cell configured by the primary network device for the terminal device (that is, the primary cell serving the terminal device) works in band1, and the carrier on which the primary cell works is called the primary carrier. In order to increase the transmission bandwidth and increase the uplink and downlink transmission rate, the primary network device can also configure one or more secondary carriers for the terminal device to form carrier aggregation. Among them, the cell corresponding to the secondary carrier is called the secondary cell, for example, the secondary cell can work in band2. Further, the main network device can also add other network devices as auxiliary network devices, and the auxiliary network device can work in band3 or band4. For example, the primary and secondary serving cell configured by the primary network device for the terminal device (that is, the primary cell under the secondary network device that provides services for the terminal device, the primary and secondary serving cell is also called the primary secondary cell (Primary Secondary Cell, Primary SCG Cell) ))) Working in band3, and the frequency band that may be used by other cells of the auxiliary network device is band4. For example, the main network device is currently working in NR technology, and the capability request message sent by the main network device is used to request the terminal device's wireless access capability in NR technology and NR-E-UTRA technology, and the capability request message carries filtering information. The filtering information includes band1 information, band2 information, band3 information, and band4 information. The wireless access capability reported by the terminal device to the network device includes at least:

3) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2) under the NR technology;

4) The wireless access capability of the terminal equipment corresponding to the combination (band1, band3) under the NR-E-UTRA technology;

5) The wireless access capability of the terminal equipment corresponding to the combination (band1, band4) under the NR-E-UTRA technology;

6) The wireless access capability of the terminal equipment corresponding to the combination (band2, band3) under the NR-E-UTRA technology;

7) The wireless access capability of the terminal equipment corresponding to the combination (band2, band4) under the NR-E-UTRA technology;

8) The wireless access capability of the terminal equipment corresponding to the combination (band1, band3, band4) under the NR-E-UTRA technology;

9) The wireless access capability of the terminal equipment corresponding to the combination (band2, band3, band4) under the NR-E-UTRA technology;

10) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band3) under the NR-E-UTRA technology;

11) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band4) under the NR-E-UTRA technology;

12) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band3, band4) under the NR-E-UTRA technology.

It should be noted that the above example shows that the terminal device also supports band1, band2, band3, and band4, so the wireless access capabilities corresponding to band1, band2, band3, and band4 are reported. If the terminal device only supports some bands of band1, band2, band3, and band4, only the wireless access capabilities corresponding to the supported partial bands will be reported. Among them, band1 and band2 are NR bands, and band3 and band4 are E-UTRA bands. Considering that the terminal equipment may be handed over, that is, it is handed over from the original base station to the new base station. Therefore, the terminal equipment can not only report the radio access capability under the single frequency band (or called single carrier) corresponding to the primary serving cell, that is, not only report one support The wireless access capability under the single frequency band (or called single carrier) can also report the wireless access capability under the single frequency band (or single carrier) corresponding to other cells, so that the new base station can refer to the single frequency band (or single carrier) of the terminal equipment. The wireless access capability under the so-called single carrier is reconfigured for terminal equipment.

As can be seen from the above example, the terminal device will report the wireless access capability corresponding to all frequency bands supported by the network device, or report the wireless access capability corresponding to all the frequency bands supported by the main network device and all the wireless access capabilities supported by the auxiliary network device. The wireless access capability corresponding to the frequency band.

In the above prior art solution, by adding filtering information to the capability request message, the terminal device can filter out some capability information that is not needed under the network device, thereby reducing the size of the capability message reported by the terminal device and reducing signaling overhead .

However, because the content of the wireless access capability of the terminal device is relatively large, even if filtering information is added to the capability request message and the size of the capability message reported by the terminal device is reduced, the capability message is still relatively large, resulting in relatively high signaling overhead. Big.

In order to further reduce the signaling overhead, the embodiment of the present application proposes to further reduce the reported wireless access capability, or it is understood that the terminal device further tailors the reported wireless access capability. Specifically, in the embodiment of the present application, the terminal device only reports the wireless access capabilities that the network device will currently use, and the terminal device may not report the wireless access capabilities that the network device currently does not use, for example, the terminal If the main serving cell of the device is working in band1, the network device will currently use the wireless access capabilities related to band1, but will temporarily not use the wireless access capabilities corresponding to other band combinations that are not related to band1. The terminal device can only The wireless access capability related to band1 is reported, but the wireless access capability corresponding to other band combinations that are not related to band1 are not reported temporarily. In this way, the signaling overhead of the terminal device when reporting the wireless access capability can be further reduced. Optionally, if the subsequent network device needs to use the wireless access capability not reported by the terminal device, the terminal device may report again based on the request of the network device.

In the prior art, the terminal device reports the wireless access capability based on the request of the network device, and the reported wireless access capability includes the wireless access capability currently used by the network device and the wireless access capability currently not used by the network device. . However, in the embodiment of the present application, the wireless access capabilities that the network device will not currently use are not reported for the time being, but only the wireless access capabilities that the network device will currently use are reported. Compared with the prior art, the embodiments of the present application can further reduce signaling overhead.

Two different scenarios are described below.

Case 1: The capability request message sent by the network device to the terminal device does not include filtering information.

It should be noted that this situation is applicable to a single-link scenario or a dual-link scenario. In the dual link scenario, the following network devices refer to the main network device.

The terminal device receives a capability request message sent by the network device, and the capability request message is used to request the terminal device's first wireless access capability under at least one wireless access technology, and the at least one wireless access technology includes at least the first wireless access technology. Access technology, the first wireless access technology is a wireless access technology that the network device works.

The terminal device determines the radio access capability related to the first cell under the first radio access technology (referred to as the second radio access capability in the embodiment of the present application). For example, the frequency band information can be used as the screening condition. If the first cell is working in the first frequency band, the terminal device can determine the wireless access capability related to the first frequency band under the first wireless access technology (that is, the second wireless access technology). ability). For another example, carrier information can also be used as a screening condition. If the first cell is working on the first carrier, the terminal device can determine the radio access capability related to the first carrier under the first radio access technology (that is, the second radio Access capability). For another example, frequency band information and carrier information can also be used as screening conditions at the same time. If the first cell works in the first frequency band and works on the first carrier, the terminal device can determine that it is in the first radio access technology and the first carrier and the first carrier. The wireless access capability related to the first frequency band (that is, the second wireless access capability).

Then, the terminal device reports the second wireless access capability to the network device.

Optionally, the reported capability message may also include the radio access capability corresponding to a single frequency band and/or a single carrier (referred to as the fourth radio access capability in the embodiment of this application), and the single frequency band here does not include the above-mentioned first frequency band. , Or it is understood that the single frequency band here refers to the frequency band supported by the network equipment except the frequency band of the main serving cell. The single carrier here does not include the above-mentioned first carrier, or it is understood that the single carrier here refers to Among the carriers supported by the network equipment, the carriers are other than those used by the primary serving cell.

Optionally, if the at least one wireless access technology mentioned above also includes the second wireless access technology, that is, the first wireless access capability requested in the capability request message also includes the wireless access of the terminal device under the second wireless access technology. Access capability (referred to as the fifth radio access capability in this embodiment), the capability message reported by the terminal device also includes the fifth radio access capability. It should be noted that the fifth wireless access capability here may be an uncut wireless access capability, or may also be a cut wireless access capability, where the cut method is the same as the cut under the first wireless access technology mentioned above. The method is similar and will not be repeated here.

It can be seen that in the prior art, the wireless access capabilities reported by the terminal device are all the wireless access capabilities of the terminal device under the first wireless access technology, that is, the wireless access capabilities requested by the corresponding network device. In the above-mentioned method in the embodiment of the present application, the wireless access capability (i.e., the second wireless access capability) reported by the terminal device is less than all the wireless access capabilities of the terminal device under the first radio access technology (i.e., the first wireless access capability). Access capability), thereby further reducing the reported wireless access capability, which can reduce signaling overhead.

For example, the first wireless access capability that the network device requests the terminal device to report includes the wireless access capability corresponding to band1, the wireless access capability corresponding to band2, and the wireless access capability corresponding to (band1, band2) under the NR technology, and the network The equipment currently works under NR technology. According to the prior art, the terminal device will report the wireless access capability corresponding to band1, the wireless access capability corresponding to band2, and the wireless access capability corresponding to (band1, band2) under the NR technology to the network device. In the embodiment of the present application, the terminal device will only report part of the wireless access capabilities of the wireless access capabilities requested by the network device to the network device. For example, the second wireless access capability reported by the terminal device includes the wireless access capability related to band1 under NR technology, that is, the wireless access capability corresponding to band1 under NR technology and the wireless access capability corresponding to (band1, band2). . Among them, the wireless access capability corresponding to band2 under NR technology is called the fourth wireless access capability. The fourth wireless access capability may not be reported to the network device temporarily, or may be reported to the network together with the second wireless access capability. equipment. For example, in this example, if the fourth radio access capability is reported to the network device together with the second radio access capability, the radio access capability reported in the prior art is the same, and the reported radio access capability cannot be tailored. Therefore, the fourth wireless access capability may not be reported in this example. Further, if the network device also requests the terminal device to report the wireless access capability corresponding to band3 under the E-UTRA technology (referred to as the fifth wireless access capability), the terminal device may also report the fifth wireless access capability to the network device. Access capability.

Case 2: The capability request message sent by the network device to the terminal device includes filtering information.

According to the capability request message and the filtering information, the terminal device determines the radio access capability corresponding to the filtering information under the first radio access technology (referred to as the third radio access capability in the embodiment of this application). That is, firstly, filter all the wireless access capabilities supported by the terminal device according to the filtering information.

Then, the terminal device screens the third wireless access capability according to the first cell. Specifically, the terminal device determines the wireless access capability related to the first cell in the third wireless access capability (referred to as the second wireless access capability in the embodiment of the present application). For example, the frequency band information can be used as the screening condition. If the first cell is working in the first frequency band, the terminal device can determine the wireless access capability related to the first frequency band in the third wireless access capability (that is, the second wireless access capability). ability). For another example, the carrier information can also be used as the screening condition. If the first cell is working on the first carrier, the terminal device can determine the radio access capability related to the first carrier in the third radio access capability (that is, the second radio access capability). Access capability). For another example, the frequency band information and carrier information can also be used as the screening conditions at the same time. If the first cell works in the first frequency band and the first carrier, the terminal device can determine the third wireless access capability and the first carrier and the first carrier. The wireless access capability related to the first frequency band (that is, the second wireless access capability).

As an implementation method, in a single link scenario, the first cell in the above scenario 1 or scenario 2 may be the primary serving cell configured by the network device for the terminal device, that is, what the terminal device reports is the wireless connection related to the primary serving cell. Entry capacity. Because when a terminal device initially accesses a cell, the cell becomes the primary serving cell of the terminal device, and other cells under the network device serve as secondary cells of the terminal device. The network device will request the terminal device to obtain the wireless access capability of the terminal device under the first wireless access technology. According to the existing technical solution, the terminal device will report all the wireless access capabilities of the terminal device under the first wireless access technology to the network device. Some of the reported wireless access capabilities are related to the primary serving cell, and some are related to the secondary cell. Community related. However, the network equipment currently only uses the terminal equipment’s wireless access capabilities related to the primary serving cell under the first wireless access technology, and will not use the terminal equipment’s wireless access capabilities related to the primary serving cell under the first wireless access technology. Therefore, in this embodiment of the application, the terminal device can first report the wireless access capability of the terminal device related to the primary serving cell under the first wireless access technology, but temporarily does not report those that are only related to the secondary cell. Wireless access capabilities related to the cell. Optionally, the above-mentioned first cell includes the primary serving cell and some secondary cells configured by the network device for the terminal device. That is, in this embodiment of the present application, the terminal device may first report the terminal device's status under the first radio access technology. Radio access capabilities related to the primary serving cell, and radio access capabilities related to some secondary cells reported under the first radio access technology, instead of reporting all the secondary cells under the first radio access technology Related wireless access capabilities. With this solution, the wireless access capability reported by the middle device can be reduced, thereby saving signaling overhead. And since the reported wireless access capability includes at least the wireless access capability currently used by the network device, it will not affect the normal communication between the network device and the terminal device.

As an implementation method, in the dual link scenario, the first cell in the above scenario 1 or scenario 2 may be the primary serving cell configured by the primary network device for the terminal device, that is, what the terminal device reports is the wireless network related to the primary serving cell. Access capability. Or the first cell is the primary and secondary cell configured by the primary network device for the terminal device, that is, what the terminal device reports is the radio access capability related to the primary and secondary cell. Or the first cell includes the primary serving cell and the primary and secondary cells, that is, what the terminal device reports is the radio access capability related to the primary serving cell and the primary and secondary cells. Because when a terminal device initially accesses a cell of the main network device, the cell becomes the primary serving cell of the terminal device, and other cells under the network device serve as the secondary cells of the terminal device. And a cell under the secondary network device of the terminal device is used as the primary and secondary serving cell of the terminal device, and other cells under the secondary network device are used as the secondary cell of the terminal device. The main network device will request the terminal device to obtain the wireless access capability of the terminal device under the first wireless access technology. According to the existing technical solution, the terminal device will report all the wireless access capabilities of the terminal device under the first wireless access technology to the primary network device. Some of the reported wireless access capabilities are related to the primary serving cell or primary and secondary serving cell. Some are related to the secondary cell. However, the network equipment currently only uses the terminal equipment’s wireless access capabilities related to the primary serving cell or primary and secondary serving cells under the first wireless access technology, and will not use the terminal equipment under the first wireless access technology. The wireless access capability is only related to the secondary cell. Therefore, in this embodiment of the application, the terminal device can first report the wireless access of the terminal device related to the primary serving cell or the primary and secondary serving cell under the first wireless access technology. Capabilities, and temporarily do not report those wireless access capabilities that are only related to the secondary cell. Optionally, the above-mentioned first cell may also include some secondary cells. That is, in this embodiment of the present application, the terminal device may first report the relationship between the terminal device and the primary serving cell and/or primary and secondary cells under the first radio access technology. The radio access capabilities related to the serving cell, and the radio access capabilities related to some secondary cells reported under the first radio access technology, instead of reporting the radio access capabilities related to all secondary cells under the first radio access technology Wireless access capability. With this solution, the wireless access capability reported by the middle device can be reduced, thereby saving signaling overhead. And since the reported wireless access capability includes at least the wireless access capability currently used by the network device, it will not affect the normal communication between the network device and the terminal device.

In the following, the above example one (single link scenario) is taken as an example to introduce the improved solution of the embodiment of the present application.

In the above example 1, according to the prior art, the above 1) to 6) will be used. In the embodiment of this application, the terminal device must report the radio access capability related to the primary serving cell (that is, the above-mentioned first cell refers to the primary serving cell) as an example, then the terminal device in the embodiment of this application reports to the network device The wireless access capability includes the second wireless access capability, which specifically includes:

2) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2) under the NR technology;

3) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band3) under the NR technology.

It can be seen that in the prior art, the network device requests the terminal device to report the first wireless access capability (that is, 1) to 6) in the above example 1, and the terminal device reports the first wireless access capability to the network device. ability. However, the second wireless access capability (that is, the above 1) to 3) reported by the terminal device to the network device in the embodiment of the present application is less than the first wireless access capability reported by the terminal device in the prior art. Among them, the second wireless access capability is the wireless access capability currently used by the network device. Therefore, in the embodiment of the present application, the signaling overhead of the terminal device can be saved.

Optionally, the wireless access capability reported by the terminal device to the network device also includes the fourth wireless access capability (that is, the wireless access capability corresponding to other single bands except band1 used by the primary serving cell), which specifically includes:

4) The wireless access capability of the terminal equipment corresponding to band2 under NR technology;

5) The wireless access capability of the terminal equipment corresponding to band3 under the NR technology.

Optionally, the wireless access capability reported by the terminal device to the network device further includes:

6) The wireless access capability of the terminal equipment corresponding to the combination (band2, band3) under the NR technology.

It should be noted that the above 1) to 3) must be reported, while 4) to 6) are optional to report, and 1) to 6) will not be reported at the same time. That is, the reported wireless access capability is less than the wireless access capability requested by the network device.

Further, if the capability request message sent by the network device is used to request the wireless access capability of the terminal device in the E-UTRA technology, the wireless access capability reported by the terminal device to the network device may also include the terminal device's wireless access capability in the E-UTRA technology. Wireless access capability (that is, the fifth wireless access capability).

It can be seen that the wireless access capability that must be reported in the embodiment of the application is only the wireless access capability currently used by the network device. Therefore, compared with the prior art, this example further reduces the reported wireless access capability. , Which can reduce signaling overhead.

It should be noted that the above example shows that the terminal device also supports band1, band2, and band3. Therefore, the wireless access capability corresponding to band1, band2, and band3 is reported. If the terminal device only supports some bands of band1, band2, and band3, it will only Report the wireless access capabilities corresponding to the supported partial bands. Considering that the terminal equipment may be handed over, that is, it is handed over from the original base station to the new base station. Therefore, the terminal equipment can not only report the radio access capability under the single frequency band (or called single carrier) corresponding to the primary serving cell, that is, not only report one support The wireless access capability under the single frequency band (or called single carrier) can also report the wireless access capability under the single frequency band (or single carrier) corresponding to other cells, so that the new base station can refer to the single frequency band (or single carrier) of the terminal equipment. The wireless access capability under the so-called single carrier is reconfigured for terminal equipment.

The following takes the above example two (dual link scenario) as an example to introduce the improved solution of the embodiment of the present application.

In the above example two, according to the prior art, the above 1) to 12) are used. In the embodiment of the present application, the terminal device must report the radio access capability related to the primary serving cell (that is, the above-mentioned first cell refers to the primary serving cell configured by the primary network device for the terminal device) as an example, then the embodiment of the present application The wireless access capability reported by the middle terminal device to the main network device includes the second wireless access capability, which specifically includes:

3) The wireless access capability of the terminal equipment corresponding to the combination (band1, band3) under the NR-E-UTRA technology;

4) The wireless access capability of the terminal equipment corresponding to the combination (band1, band4) under the NR-E-UTRA technology;

5) The wireless access capability of the terminal equipment corresponding to the combination (band1, band3, band4) under the NR-E-UTRA technology;

6) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band3) under the NR-E-UTRA technology;

7) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band4) under the NR-E-UTRA technology;

8) The wireless access capability of the terminal equipment corresponding to the combination (band1, band2, band3, band4) under the NR-E-UTRA technology.

It can be seen that in the prior art, the main network device requests the terminal device to report the first wireless access capability (that is, 1) to 12) in Example 2 above), and the terminal device reports the first wireless access capability to the main network device. Access capability. However, the second wireless access capability (that is, the above 1) to 8) reported by the terminal device to the main network device in the embodiment of the present application is less than the first wireless access capability reported by the terminal device in the prior art. Wherein, the second wireless access capability is the wireless access capability currently used by the main network device. Therefore, in the embodiment of the present application, the signaling overhead of the terminal device can be saved.

Optionally, the wireless access capability reported by the terminal device to the main network device further includes the fourth wireless access capability (that is, the wireless access capability corresponding to other single bands except band1 used by the main serving cell), which specifically includes:

9) The wireless access capability of the terminal equipment corresponding to band2 under the NR technology.

Optionally, the wireless access capability reported by the terminal device to the main network device further includes:

10) The wireless access capability of the terminal equipment corresponding to the combination (band2, band3) under the NR technology.

11) The wireless access capability of the terminal equipment corresponding to the combination (band2, band4) under the NR technology.

12) The wireless access capability of the terminal equipment corresponding to the combination (band2, band3, band4) under the NR-E-UTRA technology.

It should be noted that in this example, the above 1) to 8) must be reported, while 9) to 12) are optional to report, and 1) to 12) will not be reported at the same time. That is, the reported wireless access capability is less than the wireless access capability requested by the main network device.

Further, if the capability request message sent by the network device is used to request the wireless access capability of the terminal device in the E-UTRA technology, the wireless access capability reported by the terminal device to the main network device may also include the terminal device in the E-UTRA technology The wireless access capability (that is, the fifth wireless access capability).

It can be seen that the radio access capabilities that must be reported in the embodiment of this application are only radio access capabilities currently used by the main network device. Therefore, compared with the prior art, this example further reduces the reported radio access capabilities. Capability, which can reduce signaling overhead. It should be noted that the above example shows that the terminal device also supports band1, band2, band3, and band4, so the wireless access capabilities corresponding to band1, band2, band3, and band4 are reported. If the terminal device only supports band1, band2, band3, and band4 For some bands, only the wireless access capabilities corresponding to the supported partial bands will be reported. Among them, band1 and band2 are NR bands, and band3 and band4 are E-UTRA bands. Considering that the terminal equipment may be handed over, that is, it is handed over from the original base station to the new base station. Therefore, the terminal equipment can not only report the radio access capability under the single frequency band (or called single carrier) corresponding to the primary serving cell, that is, not only report one support The wireless access capability under the single frequency band (or called single carrier) can also report the wireless access capability under the single frequency band (or single carrier) corresponding to other cells, so that the new base station can refer to the single frequency band (or single carrier) of the terminal equipment. The wireless access capability under the so-called single carrier is reconfigured for terminal equipment.

Further, in any of the foregoing implementation methods, the terminal device carries the second wireless access capability in the capability message. Optionally, the capability message also carries indication information (which may be referred to as first indication information), and the indication information is used to indicate that the second wireless access capability is a partial wireless access capability of the first wireless access capability.

For example, when the capability request message sent by the network device is the same as the capability request message in the prior art, and the operation of reporting the tailored wireless access capability is triggered and executed by the terminal device itself, the instruction information needs to be carried in the capability message. Inform the network device that the currently reported second wireless access capability is not exactly the same as the first wireless access capability requested by the network device. Specifically, it is used to indicate that the currently reported second wireless access capability is requested by the network device Part of the wireless access capability of the first wireless access capability. Optionally, the capability message may also carry frequency band information and/or carrier information when the radio access capability is tailored.

For another example, when the network device determines that the terminal device needs to further tailor the wireless access capability according to the working frequency band and/or carrier, the network device may add an additional indication information (which may be referred to as the second indication information) in the capability request message. ) Is used to instruct the terminal device to further tailor the wireless access capability according to the working frequency band and/or the working carrier. In this case, the capability message reported by the terminal device may carry the above-mentioned first indication information), or may not carry the above-mentioned first indication information. One instruction information.

Further, in the embodiment of the present application, in any of the foregoing implementation methods, the capability message reported by the terminal device may include a first capability container for carrying the foregoing second wireless access capability. If the terminal device also reports the above-mentioned first indication information, the first indication information may be carried in the first capability container or outside the first capability container.

Taking the capability request message for requesting the wireless access capability of the terminal device under the first wireless access technology and the second wireless access technology as an example, when the terminal device sends the capability message to the network device, the capability message carries the first A capability container and a second capability container, where the first capability container is used to carry the above-mentioned second wireless access capability, and the second capability container is used to carry the wireless access capability of the terminal device under the second wireless access technology (ie Fifth wireless access capability). Optionally, the first capability container may also carry the foregoing fourth wireless access capability.

Optionally, if the terminal device also carries the foregoing first indication information, the first indication information may not be placed in any capability container, or may also be placed in the foregoing first capability container. When the first indication information is put in the first capability container, the first indication information may be specifically used to indicate that the second wireless access capability carried in the first capability container is part of the first wireless access capability and is The wireless access capability under the first wireless access technology. That is, when the first indication information is put into the first capability container, the terminal device may additionally notify the network device through the first indication information that the radio access capability under the first radio access technology is currently being tailored.

In specific implementation, as an implementation method, the function of the above-mentioned first indication information is realized by 1-bit information. When the 1-bit information is "0", it means that the wireless access capability reported by the terminal device is the first requested by the network device. A part of the wireless access capability of the wireless access capability. When the 1-bit information is "1", it means that the wireless access capability reported by the terminal device is the first wireless access capability requested by the network device. Or, when the 1-bit information is "1", it means that the wireless access capability reported by the terminal device is part of the first wireless access capability requested by the network device, and when the 1-bit information is "0", it means The wireless access capability reported by the terminal device is the first wireless access capability requested by the network device.

As an implementation method, the above-mentioned function of the first indication information may be realized by whether to send the first indication information. For example, when the capability message sent by the terminal device carries the first indication information, it indicates that the wireless access capability reported by the terminal device is part of the wireless access capability of the first wireless access capability requested by the network device. When the capability message sent by the terminal device does not carry the first indication information, it indicates that the wireless access capability reported by the terminal device is the first wireless access capability requested by the network device.

Optionally, if the capability message further includes frequency band information and/or carrier information, the frequency band information is used to indicate the first frequency band corresponding to the first cell, and the carrier information is used to indicate the first carrier corresponding to the first cell. The frequency band information And/or the carrier information is carried in a manner similar to the first indication information. The frequency band information and/or carrier information may not be placed in any capability container, or may also be placed in the aforementioned first capability container.

The following is an explanation with a specific example. For example, the capability message is UECapabilityInformation-IEs, the capability container is UE-CapabilityRAT-Container, and the first indication information is partialcapabilityind.

The first implementation method (the first instruction information is not put into any capability container) is as follows:

Wherein, ue-CapabilityRAT-ContainerList includes at least one UE-CapabilityRAT-Container. For example, the ue-CapabilityRAT-ContainerList includes two UE-CapabilityRAT-Containers, which are respectively used to record the reported second radio access capability under the first radio access and the fifth radio access capability under the second radio access.

Therefore, the UECapabilityInformation-IEs contains the first indication information and one or more UE-CapabilityRAT-Container, and the first indication information is not put into any UE-CapabilityRAT-Container, or understood as the first indication information and UE-CapabilityRAT-Container. The CapabilityRAT-Container is carried in the UECapabilityInformation-IEs in parallel.

In this example, if the first indication information field appears in a certain UE-CapabilityRAT-Container, and the field is set to the enumeration type supported, it means that the radio access capability carried by the UE-CapabilityRAT-Container is a network device request Part of the wireless access capability in the wireless access capability corresponding to the first wireless access technology. Otherwise, if the first indication information field does not appear in the UE-CapabilityRAT-Container, it means that the radio access capability carried by the UE-CapabilityRAT-Container is the radio access capability corresponding to the first radio access technology requested by the network device. The UE-CapabilityRAT-Container is used to report the radio access capability related to the first radio access technology.

The second implementation method (the first instruction information is placed in the first capability container) is as follows:

UECapabilityInformation-IEs::= SEQUENCE{

ue-CapabilityRAT-ContainerList UE-CapabilityRAT-ContainerList OPTIONAL,

}

The ue-CapabilityRAT-Container used to record the reported second radio access capability is as follows:

The ue-CapabilityRAT-Container used to record the reported fifth radio access capability is as follows:

Therefore, the UECapabilityInformation-IEs contains one or more UE-CapabilityRAT-Container, the first indication information is put into one of the UE-CapabilityRAT-Container, and the radio access capability corresponding to the radio access capability recorded by the UE-CapabilityRAT-Container The access technology is the same as the wireless access technology corresponding to the wireless access capability reported by the first indication information.

In this example, if the first indication information field appears in the UECapabilityInformation-IEs, and the field is set to the enumeration type supported, it means that the radio access capabilities reported by the UECapabilityInformation-IEs are among the radio access capabilities requested by the network device Partial wireless access capability. Otherwise, if the first indication information field does not appear in the UECapabilityInformation-IEs, it means that the radio access capability reported by the UECapabilityInformation-IEs is the radio access capability requested by the network device, that is, the radio access capability requested by the network device from the terminal device. The access capability is the same as the wireless access capability reported by the terminal device to the network device.

Based on the solution of the present application, when a terminal device initially accesses a certain cell, it can only report the radio access capabilities related to the primary serving cell and the primary and secondary serving cells, thereby saving signaling overhead. Subsequently, when the network device needs to use other wireless access capabilities of the terminal device, the network device may send a capability request message to the terminal device again to request other wireless access capabilities.

Further, when the terminal device switches from the original network device (referred to as the first network device) to the target network device (referred to as the second network device), the first network device may send a switching message to the second network device, which carries the first network device. A wireless access capability acquired by a network device (that is, the second wireless access capability in the foregoing embodiment). Optionally, the handover message may also carry indication information, which is used to indicate that the second wireless access capability is part of the first wireless access capability, or understood as used to inform the second network device: The wireless access capability currently sent to the second network device is the tailored wireless access capability. Therefore, the second network device can determine whether it needs to request another part of the wireless access capability from the terminal device again based on the indication information.

As an implementation method, the handover message includes a third capability container, and the third capability container is used to carry the second wireless access capability. As the first implementation method, the indication information is carried in the handover message but not carried in the third capability container. As the second implementation method, the instruction information is carried in the third capability container.

The following is an explanation with a specific example. For example, the handover message is HandoverPreparationInformation-IEs, the capability container is UE-CapabilityRAT-Container, and the indication information is partialcapabilityind.

The first implementation method is as follows:

Wherein, ue-CapabilityRAT-ContainerList includes at least one UE-CapabilityRAT-Container. For example, the ue-CapabilityRAT-ContainerList includes a UE-CapabilityRAT-Container, which is used to record the reported second radio access capability under the first radio access.

Therefore, HandoverPreparationInformation-IEs contains indication information and one or more UE-CapabilityRAT-Container, and the indication information is not put into any UE-CapabilityRAT-Container, or it is understood that the indication information and UE-CapabilityRAT-Container are carried in parallel In HandoverPreparationInformation-IEs.

In this example, if the indication information field appears in a certain UE-CapabilityRAT-Container, and the field is set to the enumeration type supported, it means that the radio access capability carried by the UE-CapabilityRAT-Container is requested by the first network device Part of the wireless access capabilities in the acquired wireless access capabilities corresponding to the first radio access technology. Otherwise, if the indication information field does not appear in the UE-CapabilityRAT-Container, it means that the radio access capability carried by the UE-CapabilityRAT-Container is the radio access capability corresponding to the first radio access technology requested by the first network device That is, the wireless access capability requested by the first network device from the terminal device is the same as the wireless access capability reported by the terminal device to the first network device. The UE-CapabilityRAT-Container is used to transmit the radio access capability related to the first radio access technology.

The second implementation method is as follows:

Wherein, ue-CapabilityRAT-ContainerList includes at least one UE-CapabilityRAT-Container. For example, the ue-CapabilityRAT-ContainerList includes a UE-CapabilityRAT-Container, which is used to record the second radio access capability under the first radio access.

The ue-CapabilityRAT-Container used to record the second radio access capability is as follows:

Therefore, HandoverPreparationInformation-IEs contains one or more UE-CapabilityRAT-Container, the indication information is put in one of the UE-CapabilityRAT-Container, and the radio access technology corresponding to the radio access capability recorded by the UE-CapabilityRAT-Container The radio access technology corresponding to the radio access capability indicated by the indication information is the same. In this example, if the indication information field appears in HandoverPreparationInformation-IEs, and the field is set to the enumeration type supported, it means that the wireless access capability in the HandoverPreparationInformation-IEs is the wireless access that the first network device requests from the terminal device. Part of the wireless access capability in the access capability. Otherwise, if the indication information field does not appear in the HandoverPreparationInformation-IEs, it means that the wireless access capability in the HandoverPreparationInformation-IEs is the wireless access capability obtained by the first network device from the terminal device, that is, the first network device sends the terminal device to the terminal device. The wireless access capability requested by the device is the same as the wireless access capability reported by the terminal device to the first network device.
