It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

At present, especially in NR/5G RATS (Radio Access Technology), the mobile device will support flexible/multiple configurations; the mobile device will support multiple configurations with different layer identifiers in the UE capability information from the user equipment to the network. However, the access network device configures the channel bandwidth for the UE by checking the Multi Radio Dual Connectivity (MRDC) supported by the mobile device, resulting in wireless Resource allocation and reallocation utilization is low.

The method for processing user equipment capability information provided by this application can be applied to the application environment shown in FIG. 1 . The user equipment 102 communicates with the access network device 104 through a mobile communication network. When the user equipment 102 detects that the frequency band combination configuration of the access network device 104 fails, it sends a request to the access network device 104 through the tracking area update; the request is used to request the access network device 104 to send the user equipment 102 Sending a user equipment capability query request; receiving the user equipment capability query request; updating the network configuration parameters of the access network device 104 through the user equipment capability query request, and sending the user equipment to the access network device 104 The user equipment capability information of 102; the user equipment capability information includes a first frequency band identifier that the user equipment supports to access the first wireless network and a second frequency band identifier that the user equipment supports to access the second wireless network. Among them, the user equipment 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices. The access network device 104 may be one or more base stations.

In one embodiment, as shown in FIG. 2 , a method for processing user equipment capability information is provided, and the method is applied to the user equipment 102 in FIG. 1 as an example for description, including the following steps:

Step 202, in the case of detecting that the frequency band combination configuration of the access network device fails, send a request to the access network device through tracking area update.

The request is used to request the access network device to send a user equipment capability query request to the user equipment. That is, in response to receiving the request sent from the user equipment through the tracking area update, the access network device sends the user equipment capability query request to the user equipment. The access network equipment may be a radio transceiver station (eg, base station) that transmits information between the mobile communication switching center and the user equipment in a certain radio coverage area. The access equipment provided by different network operators is different. The base station can be, for example, gNB and eNB; gNB provides NR user plane and control plane protocols and functions; eNB provides E-UTRA user plane and control plane protocols and functions. The UE capability information of the user equipment supports multiple channel bandwidth combinations with different network layer combinations, for example, the user equipment supports the LTE layer and the NR layer with 5G bandwidth, that is, the user equipment supports both 4G and 5G networks, and the user equipment's 5G system It supports a variety of Multi Radio Dual Connectivity (MRDC) bandwidth combinations below 6GHz and millimeter wave, and Eutra NR Dual Connectivity (ENDC) is a networking mode in MRDC. For example, in the ENDC coverage area, the MRDC combination of the user equipment bandwidth and the MIMO layer configuration may include the frequency band combination of the LTE layer 12 and the NR 4 layer with a bandwidth of 60 MHz, and the frequency band combination of the LTE layer 4 and the NR 4 layer with a bandwidth of 100 MHz. The user equipment can simultaneously report at least one piece of user equipment capability information to the access network device.

Specifically, when the user equipment operates in the area covered by the ENDC in the Non-Standalone (NSA) mode, the gNB and the eNB establish dual connections, and the access device sends the user equipment capability information query request to the user equipment to the user. The access layer (Access Stratum, AS) of the device reports the user equipment capability information of the user equipment to the access network device through the access layer, and the access network device configures the invalid frequency band combination supported by the user equipment according to the received user equipment capability information, namely The band combination is configured at the wrong MIMO layer; and the RRCRECONFIGURATION with the wrong MRDC is sent to the user equipment. Because the user equipment cannot follow the invalid configuration, it triggers the generation of 4G Radio Link Failure (RLF) information, and triggers RRCREESTABLISHMENT between the user equipment and the access network equipment, that is, radio resource control (RRC) re-establishment; through Tracking Area Update (TAU) ) Obtain the current location of the user equipment to re-query the user equipment capability information of the user equipment, that is, the mobile communication network needs to track the location of the user equipment UE to ensure that when a call arrives, the network can quickly and accurately deliver the call to the target UE; sends a request to the access network device through the tracking area update, and when the access network device receives the request, sends the user equipment capability query request UECapabilityEnquiry to the non-access layer (Non-Access Stratum, NAS) of the user equipment; wherein, its The request can be, but is not limited to, ue-cap needed=1.

Step 204: Receive a user equipment capability query request returned by the access network device according to the request.

Specifically, when the NAS layer of the user equipment receives the user equipment capability query request sent by the access network, it obtains data such as the bandwidth supported by the user equipment, MDRC (Multi Radio Dual Connectivity), and the current location of the user equipment, and obtains data such as the current location of the user equipment. The data such as the bandwidth, MDRC, and the current location of the user equipment are reported to the access network equipment.

Step 206: Update the network configuration parameters of the access network device through the user equipment capability query request, and send the user equipment capability information of the user equipment to the access network device.

The network configuration parameters include the frequency point number of the bandwidth supported by the access network device and the number of MIMO layers. The user equipment capability information includes a first frequency band identifier that the user equipment supports to access the first wireless network and a second frequency band identifier that the user equipment supports to access the second wireless network. The first wireless access technology may be, but is not limited to, a 4G wireless access network, and the second wireless network may be, but is not limited to, a 5G wireless access network. The first frequency band identification and the second frequency band identification are used to mark different frequency bands.

Specifically, when the access network device receives the bandwidth and MDRC data reported by the user equipment, it deletes the frequency point number of the incorrect bandwidth configured in the access network device and the number of MIMO layers of the user equipment, and updates them to those supported by the user equipment. The frequency point number of the bandwidth and the number of MIMO layers of the user equipment, and send the user equipment capability information of the user equipment to the access network device, and the access network device configures the target frequency band combination supported by the user equipment according to the received user equipment capability processing information. For example, according to the user equipment capability information, the user equipment supports MRDC frequency band combination that supports both NR 60MHz and 100MHz, while the access network equipment only supports NR 100MHz. In UE CapabilityInformation, all MRDC frequency band combinations only related to 100MHz are sent to the location user equipment that does not transmit all MRDC band combinations associated with 60MHz.

In the above user equipment capability information processing method, when the user equipment detects that the frequency band combination configuration fails, it sends a request to the access network device through the tracking area update; User equipment capability information, and update the network configuration parameters of the access network equipment to delete the invalid frequency band combination configured in the access network equipment, reduce the size of the signaling message and the encoding and decoding processing of the user capability information, and enhance the processing performance And the performance of the battery is improved and the service life of the battery is prolonged; wherein, the capability information of the user equipment includes the first frequency band identifier that the user equipment supports to access the first wireless network and the second frequency band identifier that supports access to the second wireless network; When the frequency band combination configuration fails, the user equipment capability information is re-requested for correct configuration, thereby improving the radio resource allocation and reallocation utilization.

In another embodiment, as shown in FIG. 3 , a method for processing capability information of user equipment is provided, and the method is applied to the user equipment in FIG. 1 as an example for description, including the following steps:

Step 302, when receiving the invalid frequency band combination configured by the access network device according to the initial user equipment capability information of the user equipment, generate radio link failure information.

The invalid frequency band combination refers to the frequency band combination obtained by the access network equipment only considering the bandwidth supported by the user equipment, without considering the capabilities of the MIMO layer of the user equipment; the radio link failure information (RLF) can be, but is not limited to, when the user equipment The radio link failure information generated by the frequency band combination that does not support the configuration of the access network equipment may be represented by 0 but not limited to.

Specifically, when the user equipment runs the ENDC coverage area, the access network equipment configures the invalid frequency band combination supported by the user equipment by acquiring the initial user equipment capability information of the user equipment, that is, the bandwidth supported by the user equipment, and assigns the invalid frequency band combination with the erroneous MRDC to the user equipment. RRCRECONFIGURATION is sent to the user equipment, and the user equipment cannot follow the invalid configuration, which triggers the generation of 4G Radio Link Failure (RLF) information, and triggers the RRCREESTABLISHMENT between the user equipment and the access network equipment, that is, Radio Resource Control (RRC) re-establishment.

Step 304: Trigger the radio resource control re-establishment of the user equipment and the access network equipment based on the radio link failure information, obtain an invalid frequency band combination and obtain the number of re-establishments.

Step 306, when the number of reconstructions is a preset number of times and the obtained frequency band combination is an invalid frequency band combination, it is determined that the configuration of the frequency band combination of the access network device fails.

The preset number of times refers to the maximum number of times that the RLF triggers the access network device to perform frequency band configuration again, and the preset number of times may be, but is not limited to, 5.

Step 308 , when it is detected that the configuration of the frequency band combination of the access network device fails, a request is sent to the access network device through the tracking area update.

Specifically, when the user equipment operates in the non-standalone (NSA) mode ENDC coverage area, where the gNB and the eNB establish dual connections, the access device sends the user equipment capability information query request to the user equipment to the AS layer of the user equipment , the user equipment capability information of the user equipment is reported to the access network device through the AS layer, and the access network device performs the first configuration according to the received user equipment capability information configuration, and obtains an invalid uplink frequency band combination and/or an invalid downlink frequency band combination, RRC establishment failure means that the user equipment does not support invalid uplink frequency band combinations and/or invalid downlink frequency band combinations, and the user equipment updates the categories of the invalid uplink frequency band combinations and/or invalid downlink frequency band combinations to obtain updated UE capability information. The updated UE capability information is reported to the access network device gNB, and the correct frequency band combination configuration is obtained, so that the user equipment with 5G function can use the 5G data service normally, and reside on 5G, which increases the throughput of network data and reduces the signaling overhead. As shown in FIG. 4 , the access network device (gNB) configures the invalid uplink frequency band combination and/or invalid downlink frequency band combination for the first time, resulting in RRC reconstruction; when the access network device configures the invalid uplink frequency band combination and/or invalid downlink frequency band combination for the second time When the downlink frequency band is combined, the user equipment uplink frequency band combination and/or downlink frequency band combination category is updated (for example, the uplink frequency band combination and/or downlink frequency band combination category is downgraded/upgraded), and the updated UE capability information is sent to The access network equipment makes the configuration in the access network equipment gNB obtain the correct frequency band combination to complete the configuration, avoids ping-pong handover, and improves the utilization rate of wireless resource redistribution.

Step 314: Receive the target frequency band combination configured by the access network device according to the capability information of the user equipment.

Step 316, based on the target frequency band combination, the user equipment establishes a connection with the first wireless network and the data service of the second wireless network.

Specifically, when the tracking area is completed, the target frequency band combination of the user equipment is determined, the data service between the user equipment and the access network equipment is restored, and the user equipment can access 4G and 5G services at the same time.

Optionally, in an embodiment, the frequency band combination parameters of the user equipment are acquired, and the frequency band combination parameters are sent to the access network device; the target frequency band combination configured by the access network device according to the user equipment capability information and the frequency band combination parameters is received.

Wherein, the frequency band combination parameter includes the MIMO layer of each frequency band applied to the frequency band combination of the MIMO layer and the NR MIMO layer that supports the bandwidth.

Specifically, by acquiring the frequency band combination parameters of the user equipment, and sending the frequency band combination parameters to the access network device; receiving the target frequency band combination configured by the access network device according to the user equipment capability information and the frequency band combination parameters, without signaling overhead Determine the target frequency band combination, and achieve efficient use of radio resources through allocation/reallocation of radio resources.

Optionally, in one embodiment, the camping position of the user equipment is acquired according to the user equipment capability query request; the required radio access technology capability information associated with the frequency band identifier supported by the network of the camping position is taken as the user of the user equipment. equipment capability information, and perform the step of receiving a user equipment capability query request.

Specifically, the camping position of the user equipment is obtained according to the user equipment capability query request; the required radio access technology capability information associated with the frequency band identifier supported by the network of the camping position is used as the user equipment capability information of the user equipment, and the The user equipment capability query requests to update the network configuration parameters of the access network device, and sends the user equipment capability information of the user equipment to the access network device; and receives the configuration of the access network device according to the user equipment capability information. The target frequency band combination; based on the target frequency band combination, the user equipment establishes a connection with the first wireless network and the second wireless network data service, for example, the user equipment supports the MRDC frequency band combination and supports NR60MHz and 100MHz, The network at this location only supports NR 100MHz, and in UECapabilityInformation, all MRDC band combinations related to 100MHz only are sent to the UE at this location, and all band combinations related to 60MHz are not sent. The target frequency band combination of the user equipment is determined according to the location of the user equipment, which improves the configuration efficiency of the frequency band combination.

In one embodiment, as shown in FIG. 5 , it is an application scenario of user equipment capability information processing. The mobile equipment communicates with the access network equipment (4G base station and 5G base station, gNB/eNB) on the network side through the mobile communication network. When the user equipment runs the ENDC coverage area, the access network equipment obtains the initial user equipment capability of the user equipment by Information, i.e., the bandwidth supported by the user equipment configures invalid band combinations supported by the user equipment, and sends the RRCRECONFIGURATION with the wrong MRDC to the user equipment, the user equipment cannot follow the invalid configuration, triggers the generation of 4G Radio Link Failure (RLF), triggers RRCREESTABLISHMENT, ie Radio Resource Control (RRC), is re-established between the user equipment and the access network equipment, the access network equipment tries to configure similar invalid configurations again and again, and the terminal cannot comply. For example, the user equipment supports frequency band combination 1 and frequency band combination 2 in the MRDC to be shared with the access network equipment.

Band combination 1: Band1(4*4)+3(4*4)+N78(4*4)-60Mhz bandwidth, namely LTE MIMO 8 layers and NR MIMO 4 layers;

Band combination 2:

Band1(2*2)+3(2*2)+N78(4*4)-100Mhz bandwidth, namely LTE MIMO layer 4 and NR MIMO layer 4, N78 is a frequency band of 5G.

If the user equipment operates in CA (Carrier Aggregation CA means that the base station aggregates 2 or more Component Carriers (CCs) together to provide services for the UE) mode, Band1(4*4)+3 (4*4) With Pcell as Band1, and the access network equipment supports buffer status in the coverage area of NR 100MHz bandwidth to offload data to 5G. In this case, the access network device is configuring Band1(4*4)+3(4*4)+N78(4*4)-100Mhz, but since the terminal only supports LTE MIMO layer 4 for NR 100Mhz bandwidth, so , the UE cannot follow this configuration. This will be repeated for a maximum number of retransmissions (eg, 5 retransmissions).

Since the terminal knows the reason for the failure of RRCReconfiguration (RRC reconfiguration), that is, the terminal does not support the 4G base station/5G base station configuration channel combination, the terminal will use TrackingAreaUpdate and use ue-cap needed=1 to request the access network device to request UECapabilityEnquiry, the access network The device requests UECapabilityEnquiry, updates the network configuration parameters of the access network device through the user equipment capability query request, sends the user equipment capability information of the user equipment to the access network device, and receives the target frequency band configured by the access network device according to the user equipment capability information. Combined, such as RRC reconfiguration of NR100MHZ, the tracking area is completed to restore data services, that is, user equipment can now access 4G and 5G services simultaneously.

In the above user equipment capability information processing method, when the user equipment detects that the configuration of the frequency band combination fails, a request is sent to the access network device through the tracking area update; the user equipment capability query request and the docking are sent to the user equipment through the access network device. The network configuration parameters of the network access device are updated to obtain the user equipment capability information of the user equipment, which reduces the size of the signaling message and the encoding and decoding processing of the user capability information, enhances the processing performance and improves the performance of the battery; based on the target frequency band In combination, the user equipment establishes a connection with the first wireless network and the data service of the second wireless network, that is, correct configuration is performed by re-requesting the user equipment capability information, and the utilization rate of wireless resource allocation and reallocation is improved.
