Description

Technical Field

[0001] The present disclosure relates to the field of mobile communication technologies, and in particular to a capability information processing method, device, and medium. Background Art

[0002] In a mobile communication system, base stations and user equipment (UE) can communicate accurately and efficiently based on UE capability information. UE capability information can be used to determine UE capabilities, which represent the features or functions supported by the UE. After learning the UE capabilities, the base station can correctly configure or schedule the UE to achieve efficient communication. After the UE establishes an initial connection with the base station, the base station can query the UE capabilities through the following signaling process: the base station sends a UE capability query message to the UE. This UE capability query message is used to query the UE capabilities. After receiving the UE capability query message, the UE reports the UE capabilities to the base station through the UE capability information.

[0003] UE capabilities can be categorized in various ways based on different classification dimensions. One classification method divides UE capabilities into UE-specific capabilities and band-level capabilities. For UE-specific capabilities, different UEs have different capabilities, which apply to all frequency bands supported by the UE. For band-level capabilities, different bands can have different capabilities. For example, band 31 may support a certain UE capability, but band 32 may not.

[0004] As the number of UEs in wireless networks and the functions and features supported by UEs increase, UE capability information is also increasing, and the scale of air interface transmission data in the UE capability query process continues to grow. In related technologies, in order to save air interface transmission overhead, the base station to which the UE is connected can perform partial UE capability queries based on UE capability classification when querying UE capabilities. In a classification scenario where UE capabilities are divided into band-level UE capabilities, the base station to which the UE is connected can filter the band-level UE capabilities when querying UE capabilities, that is, only query the UE capabilities associated with the band. In this case, when the UE switches cells, the previously queried band-level UE capabilities may no longer be applicable, and the UE capabilities need to be queried again. For UEs that frequently switch cells, this will greatly increase the air interface signaling overhead. Therefore, how to efficiently transmit UE capabilities is an urgent problem to be solved. Summary of the Invention

[0037] Refer to the attached Figure 1 , is a communication system architecture diagram provided by the embodiment of the present disclosure, combined with the attached Figure 1 The scenarios to which the present disclosure is applicable are described. Figure 1 The communication system 100 may include one or more base stations 10 and one or more UEs 20 that can access the base stations 10. The UEs 20 may access the wireless network through the base stations 10 to obtain services through the wireless network or communicate with other devices through the wireless network. Figure 1 The number of devices in the communication system shown is for illustration only, and the embodiments of the present disclosure are not limited thereto. Figure 1 It is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in this application.

[0038] This disclosure is for Figure 1The type of the illustrated communication system 100 is not limited. For example, it may be a long term evolution (LTE) system, a new radio (NR) system, a transition system between an LTE system and an NR system (which may be called 4.5G or LTE-A), a global system for mobile communication (GSM), a code division multiple access (CDMA) communication system, a time division code division multiple access (TD-CDMA) communication system, a wideband code division multiple access (WCDMA) communication system, and of course a future evolved communication system. In addition, it may be a hybrid networking communication system of the aforementioned multiple systems, for example, a communication system composed of an LTE system and an NR system.

[0039] Figure 1 The UE20 shown can support one or more different communication standards, for example, it can support one or more communication standards such as LTE, NR, GSM, CDMA and WCDMA.

[0040] Figure 1 The base station 10 shown can be a base station in the same type of communication system or a base station in a different type of communication system. For example, the base station 10 can be an NG-RAN node or gNB in ​​an NR system, an eNB or eNodeB (evolutionary NodeB) in an LTE system, a BTS in a GSM or CDMA communication system, an NB (NodeB) in a WCDMA communication system, a base station in a future evolved communication system, etc. Of course, it can also be a variety of base stations in the aforementioned various communication systems.

[0041] The present disclosure embodiment Figure 1The communication system 100 shown is illustrated as an NR or LTE system. For other communication systems, reference can be made to the description of the NR or LTE system in this disclosure. Accordingly, the description is made by taking the case where UE20 supports LTE or NR communication standards as an example. For the case where UE20 supports other communication standards, reference can be made to the corresponding introduction where UE20 supports LTE or NR. Moreover, the description is made by taking the case where the base station 10 is an NG-RAN node or gNB in ​​the NR system, or an eNB or eNodeB (evolutionalNodeB) in the LTE system as an example. The methods executed by the base stations in other communication systems can be referred to the description in this disclosure and will not be repeated here.

[0042] Refer to the attached Figure 2 , which is a flow chart of a UE capability query method provided by an embodiment of the present disclosure. After UE20 establishes an initial connection with base station 10, base station 10 can Figure 2 The method shown in the figure queries the capabilities of UE 20 and specifically includes the following steps.

[0043] S201: The base station 10 sends a UE capability enquiry message to the UE 20. The UE capability enquiry message is used to inquire about the capability of the UE 20.

[0044] S202 : After receiving the UE capability query message, UE 20 reports the capabilities of UE 20 to the base station 10 via UE capability information.

[0045] UE capability information refers to information related to UE capabilities. UE capabilities may include, for example, multiple-input multiple-output (MIMO) support capabilities, supported modulation and demodulation methods, maximum demodulation rate, IP address, UE location, UE power level, or other UE capabilities required for management of call establishment.

[0046] As the size of UE capability information increases, in some related technologies, in order to save air interface transmission overhead, when querying UE capabilities through a UE capability query message, the base station may not query the UE's complete capabilities, but only query part of the UE's capabilities. For example, the band-level UE capabilities can be filtered, that is, only the band-level UE capabilities related to the band supported by the base station's serving cell are queried. In this case, when the UE undergoes a cell handover, since different cells usually support different bands, the previously queried band-level UE capabilities may no longer be applicable, and a new UE capability query process needs to be initiated to re-query the UE capabilities. For UEs that frequently switch cells, this will greatly increase the air interface signaling overhead. Therefore, how to efficiently transmit UE capabilities is an issue that needs to be solved urgently.

[0047] In view of this, the present disclosure provides a capability information processing method, device and medium, which can be applied to the scenarios and Figure 1 The communication system architecture shown is described in detail below with reference to the accompanying drawings.

[0048] First, refer to Figure 3 , the embodiment of the present disclosure provides a flow chart of a capability information processing method, which is applied to a first base station, which may be Figure 1 The base station 10 in the embodiment of the present invention comprises:

[0049] S301: Send a UE capability query message to the UE, where the UE capability query message is used to query the UE's capability.

[0050] The UE capability query message includes a frequency band list (bandlist), which includes frequency bands supported by the serving cell associated with the first base station and frequency bands supported by neighboring cells of the serving cell. The serving cell associated with the first base station can be understood as the first base station covering the serving cell, supporting the serving cell, or providing wireless communication services to UEs within the serving cell.

[0051] In the embodiment of the present disclosure, when the UE accesses the first base station, the first base station may send a UE capability query message to the UE.

[0052] S302: Receive UE capability information sent by the UE according to the UE capability query message, where the UE capability information includes capability information associated with the frequency bands included in the frequency band list.

[0053] S303: Send UE capability information to the second base station, and the second base station associates with the neighboring cell. The second base station associating with the neighboring cell can be understood as the second base station covering the neighboring cell, supporting the neighboring cell, or providing wireless communication services to UEs within the neighboring cell. There can be one or more second base stations, and this is not limited to this. When there are multiple second base stations, each second base station can perform the method of the present embodiment according to the execution steps of the second base station described in the present embodiment.

[0054] In the embodiments of the present disclosure, the frequency band supported by the serving cell may also be understood as the frequency band configured for the serving cell or the frequency band supported by the associated first base station, and the frequency band supported by the neighboring cell may also be understood as the frequency band configured for the neighboring cell or the frequency band supported by the associated second base station. The frequency bands supported by the serving cell and the neighboring cell may be uniformly configured by the network management device.

[0055] Through the method provided by the embodiment of the present disclosure, the first base station can obtain not only the UE capability information related to the frequency band supported by the service cell where the UE is currently located, but also the UE capability information related to the frequency band supported by the adjacent cell of the service cell through the UE capability query message. In this way, when the UE switches to its adjacent cell, the UE capability information obtained in the original service cell is still applicable to the new service cell, and there is no need to re-query the UE capability, which can reduce the air interface signaling overhead of the UE capability query and improve the air interface transmission utilization.

[0056] In some embodiments, upon determining that a handover of the UE from the first base station to the second base station has been initiated, UE capability information is sent to the second base station. In one possible implementation, the first base station sends the UE capability information to the second base station via a handover request message. Thus, the UE capability information is sent to the second base station only upon determining that a handover of the UE from the first base station to the second base station has been initiated, thereby avoiding additional air interface overhead caused by sending the UE capability information to the second base station when the UE has not yet been handed over.

[0057] In some embodiments, the frequency band list may also include frequency bands supported by neighboring cells of the neighboring cell. In this way, even if the UE switches to a neighboring cell of the neighboring cell, there is no need to re-query the UE capabilities, which can reduce the air interface signaling overhead of the UE capability query and improve air interface transmission utilization.

[0058] In some embodiments, before sending the UE capability query message to the UE, the first base station may first obtain a frequency band list.

[0059] In one possible implementation, when the frequency band list includes frequency bands supported by the serving cell and frequency bands supported by neighboring cells, the method for obtaining the frequency band list may include: obtaining the frequency bands supported by the serving cell, receiving frequency bands supported by the neighboring cells from a second base station, and combining the frequency bands supported by the serving cell with the frequency bands received from the second base station to obtain a frequency band list, wherein any two frequency bands included in the frequency band list are different. In some possible designs, the frequency band list is obtained by combining the frequency bands supported by the serving cell with the frequency bands received from the second base station by taking a union, such that any two frequency bands included in the frequency band list are different.

[0060] In another possible implementation, when the frequency band list includes frequency bands supported by the serving cell, frequency bands supported by the adjacent cell, and frequency bands supported by the adjacent cell's neighboring cell, the method for obtaining the frequency band list may include: obtaining the frequency bands supported by the serving cell, and receiving the frequency bands supported by the adjacent cell and the frequency bands supported by the adjacent cell's neighboring cell from the second base station, wherein any two frequency bands included in the frequency bands supported by the adjacent cell and the frequency bands supported by the adjacent cell's neighboring cell are different, and combining the frequency bands supported by the serving cell with the frequency bands received from the second base station to obtain a frequency band list, wherein any two frequency bands included in the frequency band list are different. In some possible designs, when the second base station sends the frequency bands supported by the adjacent cell and the frequency bands supported by the adjacent cell's neighboring cell to the first base station, it may send the frequency band that is the union of the frequency bands supported by the adjacent cell and the frequency bands supported by the adjacent cell's neighboring cell, so that any two frequency bands included in the frequency bands supported by the adjacent cell and the frequency bands supported by the adjacent cell's neighboring cell are different.

[0061] In some embodiments, receiving, from the second base station, a frequency band supported by a neighboring cell includes:

[0062] The frequency band supported by the neighboring cell is received from the second base station through an interface establishment message or a base station configuration update message between the first base station and the second base station.

[0063] In some embodiments, receiving, from the second base station, a frequency band supported by a neighboring cell and a frequency band supported by a neighboring cell of the neighboring cell includes:

[0064] The frequency bands supported by the adjacent cell and the frequency bands supported by the neighboring cell's neighboring cell are received from the second base station through an interface establishment message or a base station configuration update message between the first base station and the second base station.

[0065] In the embodiments of the present disclosure, the interface establishment message may include an Xn interface establishment request message (Xn setup request), an Xn interface establishment response message (Xn setup response), an X2 interface establishment request message (X2 setup request), or an X2 interface establishment response message (X2 setup response). The base station configuration update message may include an eNB configuration update or an NG-RAN node configuration update.

[0066] In some embodiments, the frequency bands supported by the adjacent cell are included in the service cell information element in the interface establishment message or the base station configuration update message, or the frequency bands supported by the adjacent cell and the frequency bands supported by the neighboring cell of the adjacent cell are included in the service cell information element in the interface establishment message or the base station configuration update message.

[0067] In the embodiment of the present disclosure, the serving cell information element may be a Served Cell Information NR IE or a Served Cell Information IE.

[0068] Secondly, refer to Figure 4 , the embodiment of the present disclosure provides another capability information processing method flow chart, which is applied to the second base station, and the second base station can be Figure 1 The base station 10 in the embodiment of the present invention comprises:

[0069] S401: Receive UE capability information sent by the first base station, where the UE capability information includes capability information associated with frequency bands included in a frequency band list, where the frequency band list includes frequency bands supported by a serving cell associated with the first base station and frequency bands supported by adjacent cells of the serving cell, and adjacent cells associated with the second base station.

[0070] S402: Communicate with the UE based on the UE capability information received from the first base station.

[0071] Through the above method, the second base station can communicate with the UE based on the UE capability information obtained from the first base station. Even if the band supported by the service cell associated with the first base station is different from the band supported by the adjacent cell associated with the second base station, there is no need to initiate a new UE capability query process, which can reduce the air interface signaling overhead of the UE capability query and improve the air interface transmission utilization.

[0072] It should be noted that the concepts or steps involved in the second aspect that are the same as those in the first aspect can be found in the description of the first aspect and will not be repeated in the second aspect.

[0073] In some embodiments, the frequency band list also includes frequency bands supported by neighboring cells of adjacent cells.

[0074] In some embodiments, before receiving the UE capability information sent by the first base station, the frequency bands supported by the adjacent cells can also be sent to the first base station, or the frequency bands supported by the adjacent cells and the frequency bands supported by the adjacent cells' neighboring cells can be sent to the first base station, and any two frequency bands included in the frequency bands supported by the adjacent cells and the frequency bands supported by the adjacent cells' neighboring cells are not the same.

[0075] In some embodiments, the frequency bands supported by the neighboring cells may be sent to the first base station in the following manner: the frequency bands supported by the neighboring cells may be sent to the first base station via an interface establishment message or a base station configuration update message between the first base station and the second base station.

[0076] In some embodiments, the frequency bands supported by the adjacent cells and the frequency bands supported by the neighboring cells of the adjacent cells can be sent to the first base station in the following manner: through an interface establishment message or a base station configuration update message between the first base station and the second base station, the frequency bands supported by the adjacent cells and the frequency bands supported by the neighboring cells of the adjacent cells are sent to the first base station.

[0077] In some embodiments, the frequency bands supported by the adjacent cell are included in the service cell information element in the interface establishment message or the base station configuration update message, or the frequency bands supported by the adjacent cell and the frequency bands supported by the neighboring cell of the adjacent cell are included in the service cell information element in the interface establishment message or the base station configuration update message.

[0078] In some embodiments, when it is determined that handover of the UE from the first base station to the second base station has been initiated, the UE capability information sent by the first base station is received.

[0079] Thirdly, refer to Figure 5 , another capability information processing method flow chart provided in an embodiment of the present disclosure is applied to a UE, the UE may be Figure 1 In the UE20, the method includes:

[0080] S501: Receive a UE capability query message sent by a first base station, where the UE capability query message is used to query UE capabilities.

[0081] The UE capability query message includes a frequency band list, and the frequency band list includes frequency bands supported by the serving cell associated with the first base station and frequency bands supported by adjacent cells of the serving cell.

[0082] S502: Send UE capability information to the first base station according to the UE capability query message, where the UE capability information includes capability information associated with the frequency bands included in the frequency band list.

[0083] Through the above method, after receiving the UE capability query message sent by the first base station containing the frequency bands supported by the service cell associated with the first base station and the frequency bands supported by the adjacent cells of the service cell, the UE can simultaneously send to the first base station the UE capability information related to the frequency bands supported by the service cell where the UE is currently located and the UE capability information related to the frequency bands supported by the adjacent cells of the service cell. In this way, when the UE switches to its adjacent cell, the UE capability information obtained in the original service cell is still applicable to the new service cell, and there is no need to re-query the UE capability, which can reduce the air interface signaling overhead of the UE capability query and improve the air interface transmission utilization.

[0084] It should be noted that the concepts or steps involved in the third aspect that are the same as those in the first aspect can be found in the description of the first aspect and will not be repeated in the third aspect.

[0085] In some embodiments, the frequency band list also includes frequency bands supported by neighboring cells of adjacent cells.

[0086] In order to enable those skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present disclosure, the technical solutions provided by the embodiments of the present disclosure are further described below through specific examples:

[0087] Reference Figure 6 , is a flow chart of another capability information processing method provided in an embodiment of the present disclosure. In this embodiment, the communication system is an NR system, the UE is a UE in an NR scenario, and base station 1 and base station 2 are NG-RAN nodes or gNBs in the NR scenario. The method includes:

[0088] S601: Neighboring cell transmits frequency band list. S601 may include the following steps:

[0089] S6011: Base station 1 sends an Xn interface establishment request message (Xn setup request) to base station 2.

[0090] S6012: Base station 1 receives an Xn interface setup response message (Xn setup response) sent by base station 2.

[0091] S6013: Base station 1 sends a base station configuration update message (NG-RAN node configuration update) to base station 2.

[0092] In the embodiment of the present disclosure, the bands supported by each cell can be represented by a bandlist. For example, the bands supported by cell 1 include band1 and band2, which can be understood as the bandlist supported or configured by cell 1 includes band1 and band2.

[0093] In an embodiment of the present disclosure, the base stations associated with each neighboring cell can transmit the neighboring cell frequency band list through the newly added band_list field in the service cell information (Served Cell InformationNR) IE included in the Xn interface establishment request message, the Xn interface establishment response message, and the base station configuration update message. The base station associated with the current serving cell traverses all NR neighboring cells of the serving cell, takes the union of the bandlist supported by all NR neighboring cells and the bandlist supported by the serving cell, fills it in the band_list and passes it to the neighboring cells of the current serving cell.

[0094] Specifically, attached Figure 6 Base station 1 and base station 2 in the example can transmit neighboring frequency band lists in the following manner.

[0095] Base station 1 can send a frequency band list or an updated frequency band list to base station 2 through the Xn interface establishment request message or the newly added band_list field in the Served CellInformation NR IE contained in the base station configuration update message. The frequency band list includes the bands obtained by taking the union of the bandlist supported by the service cell associated with base station 1 and the bandlist supported by the adjacent cells of the service cell. That is, the union of the bandlist supported by the service cell associated with base station 1 and the bandlist supported by the adjacent cells of the service cell can be filled in the band_list and passed to base station 2.

[0096] Base station 2 can send a frequency band list or an updated frequency band list to base station 1 by establishing a new band_list field in the Served Cell Information NR IE contained in the response message through the Xn interface. The frequency band list includes the bands obtained by taking the union of the bandlist supported by the service cell associated with base station 2 and the bandlist supported by the adjacent cells of the service cell. That is, the union of the bandlist supported by the service cell associated with base station 2 and the bandlist supported by the adjacent cells of the service cell can be filled in the band_list and passed to base station 1.

[0097] The following is combined with Figure 7 A more general description is given of the method for neighboring cell transmission of frequency band lists in the embodiment of the present disclosure. This general method can be used not only in NR scenarios, but also in LTE scenarios, and can also be used in other independent networking or hybrid networking scenarios.

[0098] Reference Figure 7 , which is a schematic diagram of a neighboring cell transmission frequency band list provided by an embodiment of the present disclosure, Figure 7 In the example, the serving cell has two adjacent cells. The adjacent cells of adjacent cell 1 include adjacent cells a, b, and c, and the adjacent cells of adjacent cell 2 include adjacent cells x, y, and z. When exchanging neighboring cell information, the transmission of frequency band lists is added. Each cell takes the union of the bandlist supported by itself and the bandlist supported by all neighboring cells and transmits it to its neighboring cells. For example, Figure 7In the example, neighboring cell 1 can send bandlist1 to the serving cell. Bandlist1 is the result of taking the union of bandlist_1 supported by neighboring cell 1, bandlist_a supported by neighboring cell a, bandlist_b supported by neighboring cell b, and bandlist_c supported by neighboring cell c. Similarly, neighboring cell 2 can send bandlist2 to the serving cell. Bandlist2 is the result of taking the union of bandlist_2 supported by neighboring cell 2, bandlist_x supported by neighboring cell x, bandlist_y supported by neighboring cell y, and bandlist_z supported by neighboring cell z.

[0099] S602: UE access process.

[0100] When the UE accesses the service cell associated with base station 1, it traverses all neighboring cells of the service cell. Base station 1 takes the bandlist supported by the adjacent cell obtained from base station 2 associated with the adjacent cell of the service cell and the bandlist supported by the adjacent cell of the adjacent cell, and obtains the bandlist by taking the union of the bandlist supported by the adjacent cell of the adjacent cell. The obtained bandlist is obtained by taking the union of the bandlist supported by the service cell associated with base station 1 to obtain a complete bandlist. The complete bandlist can be understood as the band supported by all cells in the network where the UE is located.

[0101] During the process of the UE accessing the serving cell associated with base station 1, S602 may include the following steps:

[0102] S6021: Base station 1 sends a UE capability query message to the UE, which includes the above-mentioned complete bandlist, and uses the complete bandlist to query the UE NR capability.

[0103] S6022: Base station 1 receives UE capability information sent by the UE according to the UE capability query message. The UE capability information includes UE capability information associated with the bands included in the above complete bandlist. The band-level UE capabilities obtained in this way are all the band-level UE capabilities required under the network.

[0104] S603: Upon determining that a handover of the UE from base station 1 to base station 2 has been initiated, base station 1 sends UE capability information associated with the bands included in the complete bandlist to base station 2. In this way, after the UE is handed over to a cell associated with base station 2, it is not necessary to initiate a new UE capability query process, and the UE capability information received from base station 1 can be used to communicate with the UE.

[0105] The following still takes the NR scenario as an example to provide the implementation details.
