Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The method for processing the capability information of the user equipment provided by the application can be applied to an application environment shown in figure 1. Wherein the user equipment 102 communicates with the access network device 104 via a mobile communication network. When the user equipment 102 detects that the frequency band combination configuration of the access network equipment 104 fails, a request is sent to the access network equipment through the tracking area update; the request is used for requesting the access network equipment to send a user equipment capability query request to the user equipment; receiving the user equipment capability query request; updating network configuration parameters of access network equipment through the user equipment capability query request, and sending user equipment capability information of the user equipment to the access network equipment; the user equipment capability information includes a first band identification of the user equipment supporting access to the first wireless network and a second band identification of the user equipment supporting access to the second wireless network. Wherein the user device 102 may 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 a plurality of base stations.
In one embodiment, as shown in fig. 2, a method for processing capability information of a user equipment is provided, and the method is applied to the user equipment in fig. 1 for illustration, and includes the following steps:
step 202, in the case that the band combination configuration failure of the access network device is detected, a request is sent to the access network device through the tracking area update.
Wherein the request is for requesting the access network device to send a user equipment capability query request to the user equipment. The access network device may be a radio transceiver station (e.g. a base station) in a certain radio coverage area for information transfer with the user equipment via a mobile switching center, the access devices being provided by different network operators. The base stations may be, for example, gNB and eNB; the gNB provides NR user plane and control plane protocols and functions; the 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, e.g. the user equipment supports LTE layer and NR layer with 5G bandwidth, i.e. the user equipment supports both 4G and 5G networks, the 5G system of the user equipment supports multiple multi-radio dual connection (Multi Radio Dual Connectivity, MRDC) bandwidth combinations below 6GHz and millimeter waves, the radio dual connection (Eutra NR Dual Connectivity, ENDC) being one networking mode in MRDC. For example, in an ENDC coverage area, the MRDC combination of the user equipment bandwidth and MIMO layer configuration may include a band combination of LTE12 layer and NR 4 layer with a bandwidth of 60MHZ, and a band combination of LTE 4 layer and NR 4 layer with a bandwidth of 100 MHZ. The user equipment can report at least one piece of user equipment capability information to the access network equipment at the same time.
Specifically, when the user equipment operates in an area covered by an ENDC in a non-independent Networking (NSA) mode, wherein the gNB and the eNB establish dual connection, the Access equipment sends a user equipment capability information query request to an Access Stratum (AS) of the user equipment, the Access equipment reports the user equipment capability information of the user equipment to the Access network equipment through the Access Stratum, and the Access network equipment configures an invalid frequency band combination supported by the user equipment according to the received user equipment capability information, namely the frequency band combination is configured in an error MIMO layer; and transmitting the RRCRECONFIGURATION with the error MRDC to the user equipment, wherein the user equipment cannot follow invalid configuration, triggering generation of 4G Radio Link Failure (RLF) information, triggering RRCREESTABLISHMENT between the user equipment and the access network equipment, namely Radio Resource Control (RRC) reestablishment; acquiring the current position of the user equipment through tracking area updating (TrackingAreaUpdate, TAU) to inquire the user equipment capacity information of the user equipment again, namely the mobile communication network needs to track the position of the User Equipment (UE) so as to ensure that the network can rapidly and accurately transfer the call to the target UE when the call arrives; updating an Access network device through a tracking area to send a request, and sending a user equipment capability query request UECapacity request to a Non-Access Stratum (NAS) of user equipment when the Access network device receives the request; wherein its request may be, but is not limited to, ue-cap needed=1.
Step 204, receiving a user equipment capability query request returned by the access network equipment according to the request.
Specifically, when the NAS layer of the user equipment receives a user equipment capability query request sent by the access network, acquiring data such as a bandwidth supported by the user equipment, an MDRC, a current position of the user equipment, and the like, and reporting the acquired data such as the bandwidth, the MDRC, the current position of the user equipment, and the like to the access network equipment.
And step 206, updating the network configuration parameters of the access network equipment through the user equipment capability query request, and sending the user equipment capability information of the user equipment to the access network equipment.
The network configuration parameters comprise frequency point numbers of bandwidths supported by the access network equipment and MIMO layers. The user equipment capability information includes a first band identification that the user equipment supports access to the first wireless network and a second band identification that the user equipment supports access to the second wireless network. The first radio access technology may be, but is not limited to, a 4G radio access network and the second radio network may be, but is not limited to, a 5G radio access network. The first band identity and the second band identity are used to label different bands.
Specifically, when the access network device receives the bandwidth and the MDRC data reported by the user device, deleting the frequency point number of the wrong bandwidth and the MIMO layer number of the user device configured in the access network device, updating the frequency point number of the bandwidth supported by the user device and the MIMO layer number of the user device, sending the user device capability information of the user device to the access network device, and receiving the target frequency band combination supported by the user device capability processing configuration user device by the access network device. For example, from the ue capability information, it is known that the ue supports MRDC band combinations while supporting NR 60MHz and 100MHz, and the access network device supports only NR 100MHz, and transmits all MRDC band combinations related to only 100MHz to the ue at the location in UE CapabilityInformation, and does not transmit all MRDC band combinations related to 100 MHz.
In the above method for processing the capability information of the user equipment, when the user equipment detects that the configuration of the band combination fails, a request is sent to the access network equipment through the update of the tracking area; the access network equipment sends a user equipment capability query request to the user equipment to obtain user equipment capability information of the user equipment, and updates and deletes invalid frequency band combinations configured in the access network equipment according to network configuration parameters of the access network equipment, so that the size of signaling information and encoding and decoding processing of the user capability information are reduced, the processing performance is enhanced, the performance of a battery is improved, and the service life of the battery is prolonged; the user equipment capability information comprises a first frequency band identifier of the user equipment supporting access to a first wireless network and a second frequency band identifier supporting access to a second wireless network; when the configuration fails in the frequency band combination, the capability information of the user equipment is inquired through re-request to carry out correct configuration, so that the wireless resource allocation and the reallocation utilization rate are improved.
In another embodiment, as shown in fig. 3, a method for processing capability information of a user equipment is provided, and the method is applied to the user equipment in fig. 1 for illustration, and includes the following steps:
Step 302, when an invalid band combination configured by the access network device according to the initial user equipment capability information of the user equipment is received, generating radio link failure information.
The invalid frequency band combination refers to a frequency band combination which is obtained by the configuration of the access network equipment by only considering the bandwidth supported by the user equipment and not considering the capability of the MIMO layer of the user equipment; the radio link failure information (RLF) may be, but is not limited to, generated when the user equipment does not support the band combination configured by the access network equipment, and may be, but is not limited to, represented by 0.
Specifically, when the user equipment runs the ENDC coverage area, the access network equipment configures an invalid frequency band combination supported by the user equipment by acquiring initial user equipment capability information of the user equipment, namely, bandwidth supported by the user equipment, and sends an rrcreceonstate with an error MRDC to the user equipment, the user equipment cannot follow the invalid configuration, triggers generation of 4G Radio Link Failure (RLF) information, and triggers a rrcrecestablishmit, namely, radio Resource Control (RRC) reestablishment, between the user equipment and the access network equipment.
And step 304, triggering the radio resource control reconstruction of the user equipment and the access network equipment through the radio link fault information to obtain invalid frequency band combinations and obtain the reconstruction times.
And 306, when the number of times of reconstruction is a preset number of times and the obtained frequency band combination is an invalid frequency band combination, determining that the frequency band combination configuration of the access network equipment fails.
The preset times refer to the maximum times value that the RLF triggers the access network device to perform frequency band configuration again, and the preset times may be, but are not limited to, 5.
In step 308, when detecting that the band combination configuration of the access network device fails, a request is sent to the access network device through the tracking area update.
Step 310, a user equipment capability query request returned by the access network device according to the request is received.
And step 312, updating the network configuration parameters of the access network equipment through the user equipment capability query request, and sending the user equipment capability information of the user equipment to the access network equipment.
Specifically, updating network configuration parameters of the access network equipment through a user equipment capability query request, deleting invalid UE capability information stored in the access network equipment, and updating the UE capability information in the access network equipment to obtain current user equipment capability information of the user equipment.
Optionally, in one embodiment, the invalid uplink band combinations and/or invalid downlink band combination categories are obtained; updating the category of the invalid uplink frequency band combination and/or the invalid downlink frequency band combination, and sending the updated category to the access network equipment.
Specifically, when the user equipment operates in an area covered by an ENDC in a non-independent Networking (NSA) mode, wherein the gNB and the eNB establish dual connection, the access equipment sends a user equipment capability information query request to an AS layer of the user equipment, the AS layer reports the user equipment capability information of the user equipment to the access equipment, the access equipment performs first configuration according to the received user equipment capability information configuration to obtain an invalid uplink band combination and/or an invalid downlink band combination, the RRC fails to establish, that is, the user equipment does not support the invalid uplink band combination and/or the invalid downlink band combination, and the user equipment updates the category of the invalid uplink band combination and/or the invalid downlink band combination to obtain updated UE capability information. And reporting the updated UE capability information to the access network equipment gNB to obtain the correct frequency band combination configuration, so that the user equipment with the 5G function can normally use the 5G data service and reside in the 5G, the throughput of network data is increased, and the signaling overhead is reduced. As shown in fig. 4, the access network device (gNB) first configures an invalid uplink band combination and/or an invalid downlink band combination, resulting in RRC reestablishment; when the access network device configures the invalid uplink band combination and/or the invalid downlink band combination for the second time, the uplink band combination and/or the downlink band combination of the user device are updated (for example, the uplink band combination and/or the downlink band combination are downgraded/upgraded), and the updated UE capability information is sent to the access network device, so that the configuration in the access network device gNB is completed by the correct band combination, the ping-pong handover is avoided, and the utilization rate of the radio resource reallocation is improved.
Step 314, receiving a target frequency band combination configured by the access network device according to the user equipment capability information.
Step 316, the user equipment establishes a connection with the first wireless network and the second wireless network data service based on the target frequency band combination.
Specifically, when the tracking area is completed, that is, 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 the 4G and 5G services simultaneously.
Optionally, in one embodiment, acquiring a frequency band combination parameter of the user equipment, and sending the frequency band combination parameter to the access network equipment; and receiving a target frequency band combination configured by the access network equipment according to the user equipment capability information and the frequency band combination parameters.
Wherein the band combination parameter includes a MIMO layer and a NR MIMO layer supporting a bandwidth for each frequency band of the band combination applied to the MIMO layer.
Specifically, the frequency band combination parameters of the user equipment are obtained, and the frequency band combination parameters are sent to the access network equipment; the receiving access network device can determine the target frequency band combination according to the user equipment capability information and the frequency band combination parameter configuration without signaling overhead, and the efficient utilization of radio resources is realized through the allocation/reallocation of the radio resources.
Optionally, in one embodiment, the residence position of the user equipment is obtained according to the user equipment capability query request; the step of receiving a user equipment capability query request is performed using the required radio access technology capability information associated with the band identification supported by the network of the residence as the user equipment capability information of the user equipment.
Specifically, acquiring a residence position of the user equipment according to a user equipment capability query request; the method comprises the steps of taking required wireless access technology capability information associated with band identification supported by a network of a resident location as user equipment capability information of user equipment, updating network configuration parameters of access network equipment through a user equipment capability query request, and sending the user equipment capability information of the user equipment to the access network equipment; receiving a target frequency band combination configured by the access network equipment according to the user equipment capability information; based on the target frequency band combination, the user equipment establishes connection with the first wireless network and the second wireless network data service, for example, the user equipment supports MRDC frequency band combination and simultaneously supports NR 60MHz and 100MHz, the network at the position only supports NR 100MHz, all MRDC frequency band combinations only related to 100MHz are sent to the UE at the position in UECapacity information instead of 60MHz, and the target frequency band combination of the user equipment is determined according to the position of the user equipment, so that the configuration efficiency of the frequency band combination is improved.
In one embodiment, as shown in fig. 5, the application scenario for the capability information processing of the user equipment is shown. The mobile device communicates with access network devices (4G base station and 5G base station, gNB/eNB) on a network side through a mobile communication network, when the user device runs an ENDC coverage area, the access network device configures an invalid frequency band combination supported by the user device by acquiring initial user device capability information of the user device, namely bandwidth supported by the user device, and sends RRCRECONFIGURATION with error MRDC to the user device, the user device cannot follow the invalid configuration, trigger generation of 4G Radio Link Failure (RLF), trigger RRCREESTABLISHENT between the user device and the access network device, namely Radio Resource Control (RRC) reestablishment, the access network device again and again tries to configure similar invalid configuration, and a terminal cannot follow the invalid configuration. For example, the user equipment supports the sharing of band combination 1 and band combination 2 with the access network equipment in the MRDC.
Band combination 1: band1 (4*4) +3 (4*4) +n78 (4*4) -60Mhz bandwidth, namely LTE MIMO 8 layer and NR MIMO 4 layer;
band combination 2:
band1 (2 x 2) +3 (2 x 2) +n78 (4*4) -100Mhz bandwidth, namely LTE MIMO 4 layer and NR MIMO 4 layer, N78 being one Band of 5G.
If the UE is operating in CA (carrier aggregation CA means that the base station aggregates 2 or more component carriers (Component Carrier, CC) to serve the UE together), band1 (4*4) +3 (4*4) is implemented with Pcell as Band1, and the access network device 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 supports LTE MIMO 4 layer only for NR 100Mhz bandwidth, the UE cannot follow the configuration. This operation will be repeated for a maximum number of retransmissions (e.g., a number of retransmissions of 5).
Since the terminal knows the reason that rrcrecon configuration (RRC reconfiguration) fails, i.e. the terminal does not support 4G base station/5G base station configuration channel combination, the terminal will use trackingarea update and request the access network device to request ue capability requirement with ue-cap needed=1, the access network device requests ue capability requirement to update network configuration parameters of the access network device through the user device capability query request, user device capability information of the user device is sent to the access network device, the target frequency band combination configured by the access network device according to the user device capability information, such as RRC reconfiguration of NR 100MHZ, and the tracking area completes recovery data service, i.e. the user device can now access both 4G and 5G services.
