Fig. 1 is a flowchart illustrating a method for storing UE capabilities according to an exemplary embodiment, and as shown in fig. 1, the method for storing UE capabilities is applied to a gNB under a non-independent networking NSA architecture, and includes the following steps:
step S101, receiving addition request information sent by eNB establishing dual connectivity, wherein the addition request information comprises UE capability information and identification ID of eNB.
In specific implementation, the gNB establishes dual connectivity (e.g., EN-DC dual connectivity) with the eNB, receives ADDITION REQUEST information sent by the eNB establishing dual connectivity with the gNB, where the ADDITION REQUEST information may be an SGNB ADDITION REQUEST signaling, and may be decoded by software to obtain UE capability information, and determines an ID of the eNB through a MeNB Cell ID field in the SGNB ADDITION REQUEST signaling, where the ID of the eNB and the eNB have a corresponding relationship.
In practical applications, as shown in fig. 2, in the network architecture diagram of the NSA architecture, the gbb and the eNB may be devices manufactured by the same manufacturer or devices manufactured by different manufacturers, and are determined by an operator for networking, for example, when the operator purchases eNB devices of the manufacturer a and gbb devices of the manufacturer a, the operator networks the same manufacturer, and when the operator purchases eNB devices of the manufacturer a and gbb devices of the manufacturer B, the operator networks the different manufacturers. Under the NSA framework, when a different manufacturer networks, the addition request information between the gNB and the eNB can be appointed, so that the gNB can acquire the UE capability information and the ID of the eNB sending the addition request information from the received addition request information.
It should be noted that the method for storing the UE capability shown in the embodiment of the present invention may be applied to an NSA architecture network of a same manufacturer networking, and may also be applied to an NSA architecture network of a different manufacturer networking.
In one possible embodiment, the gNB may establish dual connectivity with multiple enbs, that is, the gNB may establish dual connectivity with multiple enbs at the same time, and may receive addition request information sent by multiple enbs that establish dual connectivity.
Step S102, determining a frequency point number corresponding to the ID of the eNB, and determining a frequency band number corresponding to a frequency point number interval to which the frequency point number belongs according to the frequency point number and a pre-stored corresponding relation between the frequency point number interval and the frequency band number, wherein the frequency band number is a reserved frequency band number.
In specific implementation, the gNB may determine the frequency point number corresponding to the eNB ID in the received EN-DC dual connectivity REQUEST message, for example, find the frequency point number of the eNB in the Served E-UTRA Cell Information in the EN-DC X2 SETUP REQUEST.
The pre-stored frequency point number interval and frequency band number corresponding relationship, as shown in fig. 3, the first column is a frequency band number, the fourth column is a frequency point number interval, the pre-divided frequency point number interval has a unique corresponding frequency band number, and the frequency point number interval to which the frequency point number belongs and the frequency band number corresponding to the frequency point number interval to which the frequency point number belongs can be determined according to the frequency point number.
For example, the frequency point number of the eNB is 400, the belonging frequency point number interval is 0-599, the corresponding frequency BAND number of the interval is BAND1, the frequency BAND number corresponding to the frequency point number of the eNB 400 is determined to be BAND1, and the frequency BAND number corresponding to the determined frequency point number of the eNB is a reserved frequency BAND number.
Step S103, deleting some or all of the frequency band combinations that do not include the reserved frequency band number and the first frequency band number in the UE capability information, where the first frequency band number is one or more of the frequency band numbers corresponding to the frequency band capabilities supported by the gNB.
In specific implementation, the gNB receives UE capability information in the addition request information sent by the eNB establishing dual connectivity, and includes a plurality of BAND combinations, for example, EUTRA BAND3+ NR BAND41, EUTRA BAND3+ NR BAND42, where "m" in EUTRA BAND indicates a BAND number corresponding to a BAND capability supported by the eNB, and "n" in NR BAND indicates a BAND number corresponding to a BAND capability supported by the gNB.
In the UE capability information, a BAND combination that does not partially or entirely include the reserved BAND number and the first BAND number is deleted, for example, the reserved BAND number (i.e., the BAND number corresponding to the eNB bin number determined in step S103) is EUTRA BAND3, the first BAND number (i.e., the BAND number corresponding to the BAND capability supported by the gNB) is NR BAND41, a BAND combination other than the BAND combination of "EUTRA BAND3+ NR BAND 41" in the UE capability information may be deleted, and a BAND combination that does not include "EUTRA BAND 3" or "NR BAND 41" in the BAND combination may be deleted.
For another example, the reserved BAND number (i.e., the BAND number corresponding to the eNB frequency point number determined in step S103) is EUTRA BAND3, the first BAND number (i.e., the BAND number corresponding to the BAND capability supported by the gNB) is NR BAND41 and NR BAND42, and other BAND combinations except the BAND combination of "EUTRA BAND3+ NR BAND 41" and "EUTRA BAND3+ NR BAND 42" in the UE capability information may be deleted, and a BAND combination not including "EUTRA BAND 3", or "NR BAND 41", or "NR BAND 42" in the BAND combination may be deleted.
When the gNB establishes dual connectivity with multiple enbs, there may be multiple reserved BAND numbers, for example, the reserved BAND numbers are EUTRA BAND3, EUTRA BAND5, the first BAND numbers are NR BAND41 and NR BAND42, other BAND combinations than "EUTRA BAND3+ NR BAND 41", "EUTRA BAND3+ NR BAND 42", "EUTRA BAND5+ NR BAND 41" and "EUTRA BAND5+ NR BAND 42" in the UE capability information may be deleted (it should be understood by those skilled in the art that the reserved BAND combinations are all permutation combinations of the reserved BAND numbers and the first BAND numbers), and BAND combinations that do not include "EUTRA BAND 3", or "EUTRA BAND 5", or "NR BAND 41", or "NR BAND 42" in the BAND combinations may also be deleted.
In the UE capability information, the deleting part does not contain the frequency band combination of the reserved frequency band number and the first frequency band number, the complexity of searching the UE capability when the gNB uses the UE capability can be reduced, the query time is reduced, in the UE capability information, all the frequency band combinations which do not contain the reserved frequency band number and the first frequency band number are deleted, the reserved UE capability can be regarded as the combined capability (effective UE capability information) required by the gNB, when the UE capability is used, the searching of the frequency band capability is not required, and the complexity of using the UE capability is reduced.
Step S104, storing the UE capability information after deleting the frequency band combination.
In specific implementation, the gbb stores the UE capability information after deleting the BAND combination, so as to avoid storing a large amount of invalid UE capability information, and save a large amount of storage space, for example, there are 1000 UEs in the network, and the BAND numbers of the enbs supported by the UEs are EUTRA BAND1 to EUTRA BAND10, and the BAND numbers of the enbs supported by the UEs are NR BAND1 to NR BAND10, so that one UE capability may be 100 UE capability information, and if one UE capability information (one BAND combination) occupies 10k of memory, and only one UE capability information (one BAND combination) that can be supported is reserved after deleting the BAND combination by the gbb, 1000 × 99 × 10k — 990M can be saved.
Fig. 4 is a flowchart illustrating a method for acquiring a UE capability according to an exemplary embodiment, and as shown in fig. 4, the method for acquiring a UE capability is applied to an eNB under an NSA architecture, and includes the following steps:
step S401, sending a request for inquiring UE capability to at least one UE establishing connection, where the request for inquiring UE capability includes a specified frequency band combination, and the request for inquiring UE capability is used to instruct the UE to feed back capability information of the UE on the specified frequency band combination, where the specified frequency band combination is a combination of a frequency band capability supported by the eNB and a frequency band capability supported by the gNB establishing dual connection with the eNB.
In specific implementation, the eNB may send a request for querying a UE Capability to one UE that establishes a connection, or may send a request for querying a UE Capability to multiple or all UEs that establish a connection, where the eNB may send the request for querying a UE Capability through a UE Capability acquisition signaling, where the request for querying a UE Capability includes a specified frequency band combination (one or more of combinations of a frequency band Capability supported by the eNB and a frequency band Capability supported by the gNB), and the specified frequency band combination may be information of a requested frequency band bandwidth nr-MRDC-15 field in the UE Capability acquisition signaling when the eNB sends the request for querying a UE Capability through the UE Capability acquisition signaling.
For example, the eNB may support BAND capabilities of EUTRA BAND3, EUTRA BAND5, the gNB may support BAND capabilities of NR BAND41 and NR BAND42, and the specified BAND combinations may be "EUTRA BAND3+ NR BAND 41", "EUTRA BAND3+ NR BAND 42", "EUTRA BAND5+ NR BAND 41", "EUTRA BAND5+ NR BAND 42" (it should be understood by those skilled in the art that the specified BAND combinations are all permutation combinations of the BAND capabilities supported by the eNB and the gNB).
The eNB may send the request for querying UE capability to at least one UE that establishes connection again, and the specified frequency band combinations included in the request for querying UE capability sent again may be the same or different.
The eNB sends the request information for inquiring the UE capability to instruct the UE to feed back the capability information of the UE on the specified frequency band combination, that is, instruct the UE to feed back the valid UE capability information, where the frequency band combination is supported by the eNB and the gNB.
It should be noted that the request for inquiring UE capability may include a specified frequency band combination, or a frequency band capability that can be supported by the eNB currently, and the request information for inquiring UE capability sent by the eNB may also be used to instruct the UE to feed back the frequency band combination that the UE includes the frequency band capability supported by the eNB.
In one possible implementation, the eNB establishes dual connectivity with multiple gnbs, and a specified frequency band combination in the query UE capability request sent by the eNB to the UE may include one or more of the supported frequency band capabilities of the multiple gnbs.
Step S402, receiving UE capability information fed back by the UE, wherein the UE capability information only includes the capability information of the UE on the appointed frequency band combination.
In specific implementation, the eNB receives the fed back UE Capability Information, and may obtain the Capability Information of the UE on the specified frequency band combination by receiving the UE Capability Information signaling.
Step S403, sending an addition request message to the gNB that establishes the dual connectivity, where the addition request message includes UE capability information.
In specific implementation, the eNB sends an ADDITION REQUEST message to the gNB that establishes dual connectivity, and may notify the gNB of the UE capability information through a UE-capability rat-contermintlist field in an SGNB ADDITION REQUEST signaling.
In practical application, under an NSA framework, when a different manufacturer performs networking, addition request information between the eNB and the gNB may be agreed, and the eNB may put the UE capability information and the ID of the eNB into the agreed addition request information, so that the gNB knows the UE capability information reported by the eNB.
Fig. 5 is a flowchart illustrating a method for reporting a UE capability according to an exemplary embodiment, where as shown in fig. 5, the method for reporting a UE capability is applied to a UE under an NSA architecture, and includes the following steps:
step S501, receiving a UE capability query request sent by an eNB establishing a connection, where the UE capability query request includes a specified frequency band combination, and the UE capability query request is used to indicate that UE feedback only includes capability information of the specified frequency band combination, where the specified frequency band combination is a combination of a frequency band capability supported by the eNB and a frequency band capability supported by a gNB establishing a dual connection with the eNB.
In specific implementation, the UE receives an inquiry Capability request sent by the eNB for establishing a connection, for example, a UE Capability acquisition signaling, and determines, by referring to a specified frequency band combination in the inquiry Capability request (for example, information of a field requestfreqbandsrmrdc-r 15 in the UE Capability acquisition signaling), UE Capability information of the specified frequency band combination reported by the eNB for indicating the UE.
Step S502, UE capability information is sent to the eNB, and the UE capability information only contains the capability information of the UE on the appointed frequency band combination.
In specific implementation, the UE may send UE capability information to the eNB through the UE capability information signaling, and report the UE capability information of the specified frequency band combination, so that the eNB or the gNB receives effective UE capability information, thereby avoiding reporting all UE capability information of the UE.
In a possible implementation, the UE establishes connections with a plurality of enbs, and reports capability information on a corresponding designated frequency band combination to a corresponding eNB according to an indication for receiving the eNB and sending a query about the capability of the UE.
Fig. 6 is a flowchart illustrating a method for storing UE capability when a gNB, an eNB, and a UE interact on three sides according to an exemplary embodiment, where as shown in fig. 6, the method for storing UE capability includes the following steps:
step S601, eNB sends a request for inquiring UE capability to UE, wherein the request for inquiring capability contains a specified frequency band combination.
In specific implementation, the eNB may send a request for querying the UE Capability to the UE through the UE Capability establishment signaling, where the request for querying Capability includes a specified frequency band combination that may be obtained from the field information of requested frequency bands NR-MRDC-r15 in the UE Capability establishment signaling, and the specified frequency band combination may be one or more combinations of the eNB supported frequency band Capability and the gbb supported frequency band Capability.
Step S602, the UE sends UE capability information to the eNB, where the UE capability information only includes capability information of the UE on a specified frequency band combination.
In specific implementation, the UE may send, according to the received indication for querying the UE capability request, UE capability information to the eNB sending the request for querying the UE capability through a UE capability information signaling, where the capability information reported to the eNB only includes capability information of the UE on a specified frequency band combination, instead of reporting UE capability information of all UEs.
Step S603, the eNB sends addition request information to the gNB, where the addition request information includes UE capability information.
In specific implementation, the eNB may send the ADDITION REQUEST information to the gNB through an SGNB ADDITION REQUEST signaling, and the UE capability information may be carried in a UE-capability rat-ContainerList field in the SGNB ADDITION REQUEST signaling.
In step S604, the gNB acquires the UE capability information and the eNB ID from the addition request information transmitted by the eNB.
In particular implementation, the gbb may determine the ID of the eNB through the MeNB Cell ID field in the SGNB ADDITION REQUEST.
Step S605, the gNB determines the frequency point number corresponding to the eNB ID.
