[0051] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0052] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application.

[0053] like Figure 1 As shown, the wireless communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0054] It should be understood that the embodiments of the present application are only exemplified by the wireless communication system 100, but the embodiments of the present application are not limited thereto. That is to say, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine Type Communications (eMTC) system, the 5th generation mobile communication technology (5G) communication system (also known as New Radio (NR) communication system), or future communication systems, etc.

[0055] exist Figure 1 In the wireless communication system 100 shown, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area, and may communicate with the terminal device 110 (eg, UE) located in the coverage area.

[0056] In addition, the access network device provides services for the cell, and the terminal device 110 communicates with the access network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell may be a cell corresponding to the access network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0057] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0058] The wireless terminal device 110 includes but is not limited to any terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0059] For example, the terminal device 110 may refer to a reduced capability (RedCap) terminal, an access terminal, a user equipment (UE), a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network or a terminal device in a future evolution network, etc.

[0060] It should be noted that the RedCap terminal is a lightweight 5G terminal developed by the 3rd Generation Partnership Project (3GPP) Release 17 (R17), which is suitable for scenarios such as video surveillance, wearables, and industrial sensors. In terms of mobility, the RedCap terminal inherits the 5G New Radio (NR) capabilities, supports cell reselection, same-frequency / different-frequency switching, and inter-system interoperability with the 4th generation mobile communication technology (4G). Compared with the enhanced mobile broadband (eMBB) defined in 5G Release 15 (R15) / Release 16 (R16), the RedCap terminal developed by R17 reduces the complexity of the terminal by reducing the bandwidth of the user equipment (UE), reducing the number of transmitting and receiving antennas, reducing the modulation order, and adjusting the duplex mode, so as to balance the performance and cost requirements of some IoT services. Table 1 is a comparison table of the performance supported by a RedCap terminal, such as a RedCap UE, and an NR terminal in the related technology, such as an NR UE, in the receiving frequency range 1 (Frequency Range 1, FR1) band.

[0061] FR1 NR UE FR1 RedCap UE Maximum channel bandwidth 100MHz 20MHz Antenna Capability 2T4R 1T1R or 1T2R Maximum modulation order Minimum 256QAM Minimum 64QAM Duplex Mode FD-FDD, TDD FD-FDD, TDD, HD-FDD

[0062] Table 1

[0063] Among them, in terms of maximum channel bandwidth, the FR1 band reduces the maximum channel bandwidth supported by RedCap UE to 20MHz based on the 100MHz bandwidth of NR UE to match the 5G terminal communication with relatively low business demand; in terms of antenna capability, the number of antennas of NR UE supports 2 downlink antennas transmission and 4 uplink antennas reception (2Transmit 4Receive, 2T4R), while the number of antennas of RedCap UE is reduced to support 1 downlink antenna transmission and 1 uplink antenna reception (1Transmit 1Receive, 1T1R), or 1 downlink antenna transmission and 2 uplink antenna reception (1Transmit 2Receive, 1T2R); the maximum modulation order is also reduced from 256 orthogonal amplitude modulation (Quadrature Amplitude Modulation, QAM) to a minimum of 64QAM; for duplex mode, NR UE supports full duplex (Full Duplex, FD)-frequency division duplex (Frequency Division Duplex, FDD) and time division duplex (Time Division Duplex, TDD), while RedCap The UE supports FD-FDD, TDD, and half-duplex (Half Duplex, HD)-FDD duplex modes. The NR UE supports full-duplex (Full Duplex, FD)-frequency division duplex (FDD) and time division duplex (Time Division Duplex, TDD).

[0064] The terminal device 110 may be used for device-to-device (D2D) communication.

[0065] The wireless communication system 100 may also include a core network device 130 for communicating with the base station, and the core network device 130 may be a 5G core network (5G Core, 5GC) device, for example, an access and mobility management function (Access and Mobility Management Function, AMF) device, for example, an authentication server function (Authentication Server Function, AUSF) device, for example, a user plane function (User Plane Function, UPF) device, for example, a session management function (Session Management Function, SMF) device. Optionally, the core network device 130 may also be an evolved packet core (Evolved Packet Core, EPC) device of the LTE network, for example, a session management function + core network data gateway (Session Management Function + Core Packet Gateway, SMF + PGW-C) device. It should be understood that SMF + PGW-C can simultaneously implement the functions that SMF and PGW-C can implement. During the network evolution process, the name of the above-mentioned core network device may change, or a new network entity may be formed by dividing the functions of the core network, which is not limited to the embodiments of the present application.

[0066] Figure 1 A base station, a core network device and two terminal devices are shown exemplarily. Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0067] It should be noted that Figure 1It is only to illustrate the system to which the present application is applicable in the form of an example. Of course, the method shown in the embodiment of the present application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiment of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, B can be obtained through C; it can also mean that there is an association relationship between A and B. It should also be understood that the "correspondence" mentioned in the embodiment of the present application can mean that there is a direct or indirect correspondence relationship between the two, or it can mean that there is an association relationship between the two, or it can mean that there is an indication and being indicated, configuration and being configured, etc. It should also be understood that the "predefined" or "predefined rules" mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined may refer to the definition in the protocol. It should also be understood that in the embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0068] For ease of understanding the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0069] Before explaining this application, the interoperability within a mobile communication system, such as 5G R15 / R16, and between mobile communication systems, such as 4G and 5G, in the related art is described:

[0070] Interoperability within and between mobile communication systems includes but is not limited to cell reselection, handover, and redirection. Table 2 is a table of interoperability support between 4G and 5G in related technologies.

[0071]

[0072] Table 2

[0073] Among them, the serving cell, also known as the source cell, is the current resident cell of the terminal, that is, the cell currently providing services to the terminal; the target cell is the cell after interoperation. The serving cell can be a cell supporting 4G network or a cell supporting 5G network. The target cell can be a cell supporting 4G network or a cell supporting 5G network; "√" in Table 2 is used to indicate support; "-" is used to indicate non-support.

[0074] For switching between networks with different communication standards, for example, if the terminal is a 4G / 5G dual-mode terminal, the 4G R15 network only supports identifying whether the terminal supports 5G, but does not support UE capability identification of 5G terminals. If there are 5G cells around the 4G cell, the 4G cell will switch or redirect the terminal to the 5G cell based on the measurement results reported by the terminal capabilities. If the 5G terminal is a terminal that only supports closed access user groups (Closed Access Group only, CAG only), but the neighboring cell is a 5G R15 base station or a base station that does not support the CAG identity document (ID) signed by the terminal, the terminal will not be able to access the cell successfully. The terminal will search for the 5G cell or 4G cell again. If it cannot find a suitable 5G cell, it will re-access the 4G cell. Since the frequency priority of 5G is higher than that of 4G, there will be a problem of the terminal ping-pong between 4G / 5G. If the terminal is a RedCap terminal and the adjacent cell is a 5G R15 / R16 base station, after the terminal measures a 5G cell that meets the threshold requirements, the 4G base station will switch or redirect it to the 5G cell. If the terminal access fails, the terminal will search for the 5G cell or 4G cell again. If no suitable 5G cell can be found, it will re-access the 4G cell. The terminal will also experience the problem of ping-pong between 4 / 5G.

[0075] For switching between networks of the same communication standard, when switching from a high-version base station to a low-version base station, the switching may fail because the low-version base station does not support the relevant high-version capabilities. R18 newly defines new capabilities such as 5M bandwidth RedCap terminals and low-rate RedCap terminals. If the base stations do not exchange related support capabilities or configuration information, the R18 base station may switch the terminal to the R17 base station, resulting in terminal access failure or failure to schedule in the new cell.

[0076] Figure 2 A flow chart of a communication method for a terminal mobile process provided in an embodiment of the present application is shown as follows: Figure 2 As shown, this method is applied to Figure 1 In the wireless communication system 100 shown, the method includes:

[0077] Step 201: A first terminal sends first information of the first terminal to a first device.

[0078] The first information represents the capabilities supported by the first terminal and / or the subscription information associated with the interoperability service in the first terminal; the first device is a network device corresponding to the current resident cell of the first terminal.

[0079] In the embodiment of the present application, the first terminal, i.e. Figure 1 The terminal device 110 in the embodiment sends the terminal performance information of the first terminal to the first device, that is, Figure 1 The network device 120 in FIG. 1 is a network device 120. It should be noted that the first terminal can send its own terminal performance information to the first device through dedicated signaling.

[0080] In the embodiments of the present application, the first terminal may be one or more than one, that is, the first terminal only refers to multiple terminals of the same type; the present application does not specifically limit the number of first terminals.

[0081] In the embodiment of the present application, the signal area of ​​the current resident cell of the first terminal can cover the current resident area of ​​the first terminal. The current resident cell can be the cell with the best signal in the current resident area, or can be a cell that meets the resident condition among multiple cells covering the current resident position of the first terminal.

[0082] The cells that meet the residency conditions include cells that support one or more specific functions. If there are multiple cells that meet the residency conditions, the current residency cell may be any one of the multiple cells that meet the residency conditions, or may be a cell with the best signal among the multiple cells that meet the residency conditions.

[0083] Here, the present application may determine the cell with the best signal based on the parameters of the signal quality of the cell. The parameters of the signal quality of the cell may include, but are not limited to, one or more of the following: reference signal receiving power (RSRP), received signal strength indicator (RSSI), reference signal receiving quality (RSRQ), received signal level (RSL).

[0084] In the embodiment of the present application, the terminal performance information of the first terminal is sent in the following ways: in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0085] In an embodiment of the present application, the capabilities supported by the first terminal include at least one of the following: whether the first terminal is a reduced performance (RedCap) terminal, and whether the first terminal supports a closed access user group (CAG) and / or, the contract information includes at least one of the following: whether the contract is signed to support only closed access user group access, a list of closed access user group identifiers (CAGIDs) signed, a guaranteed bit rate (Guaranteed Bit Rate, GBR) signed, and a list of slices signed.

[0086] In the embodiment of the present application, a cell with CAG enabled is only allowed to be accessed by a contracted terminal. When a terminal signs up for CAG, two pieces of information will be configured in the contract information, one is the CAG ID list (allowed CAG list) of the terminal that is allowed to access, which stores the IDs of all CAG cells that the current terminal can access, and the other is the CAG unique indication (CAG only indication) indicating whether the terminal can only access the network through the CAG cell. A terminal configured with this indication can only access the network through the CAG cell. A CAG terminal configured with CAG only indication can only select an accessible CAG cell to access the network according to its own allowed CAG list.

[0087] That is to say, if the first terminal does not support CAG, then the first terminal cannot access the CAG only neighboring cell; if the first terminal is a CAG only terminal, it can only access the network through the CAG neighboring cell, and cannot access the network through the non-CAG neighboring cell. If the CAG ID list signed by the first terminal does not include the neighboring cell to be switched / redirected / reselected, then the first terminal fails to switch / redirect / reselect. In this way, the present application sends in advance whether the first terminal supports CAG / whether it has signed a contract to support only closed access user group access / the CAG ID list signed by the first terminal to the first device. Subsequently, the first device can generate corresponding strategies in a timely manner according to whether the first terminal supports CAG / whether it has signed a contract to support only closed access user group access / the CAG ID list signed by the first terminal, thereby avoiding the problem that the unsupported first terminal wants to switch / redirect / reselect a CAG neighboring cell, resulting in a switching / redirection / reselection failure, or avoids the problem that the terminal signed a contract to support only closed access user group access wants to switch / redirect / reselect a non-CAG neighboring cell, resulting in an inability to access the network, or avoids the problem that the first terminal wants to switch / redirect / reselect a neighboring cell that is not included in the signed CAG ID list, resulting in an inability to access the network.

[0088] In the embodiment of the present application, whether the first terminal is a RedCap terminal, that is, whether the first terminal supports RedCap. It should be noted that according to the existing 3GPP specification requirements, the 5G network accessed by the RedCap terminal needs to be upgraded to the 3GPP R17 standard. In other words, during the movement of the first terminal, some neighboring cells do not support the access of the RedCap terminal due to the communication protocol version, resulting in the failure of the first terminal to switch / redirect / reselect. In this way, the present application sends whether the first terminal is a RedCap terminal to the first device in advance. Subsequently, the first device can generate corresponding strategies in time according to whether the first terminal is a RedCap terminal to avoid the failure of the first terminal to switch / redirect / reselect.

[0089] In the embodiment of the present application, GBR, that is, the minimum bit rate guaranteed by the system to carry, during the movement of the first terminal, if the GBR supported by some neighboring cells is smaller than the GBR subscribed by the first terminal, or the GBR of the neighboring cells is not effective, then the experience of the first terminal after switching / redirection / reselection cannot be guaranteed; in this way, the present application sends the GBR subscribed by the terminal to the first device in advance, and subsequently, the first device can generate a corresponding strategy in time according to the subscribed GBR to avoid a deterioration in the experience of the first terminal after switching / redirection / reselection.

[0090] In an embodiment of the present application, the tracking area of ​​the base station supports slice 1 and slice 2. If the slice list subscribed by the first terminal does not include slice 1 and slice 2, the first terminal may not be able to switch / redirect / reselect to the cell corresponding to the base station. Therefore, the present application sends the slice list subscribed by the terminal to the first device in advance. Subsequently, the first device can generate a corresponding strategy in time according to the subscribed slice list to avoid the failure of switching / redirection / reselection of the first terminal.

[0091] Step 202: The first device receives first information sent by the first terminal.

[0092] Step 203: The first device obtains attribute information of at least one second device.

[0093] The second device is a network device corresponding to a neighboring cell of the current resident cell of the first terminal.

[0094] In an embodiment of the present application, the attribute information of the network device includes at least one of the following: the release (Release) version of the network device, the tracking area (Tracking Area, TA) configured by the network device, the slice resource reservation method and proportion of the network device, the minimum bit rate (Minimum Bit Rate, MinBR) configured by the network device, the priority bit rate (prioritized bit rate, PBR) configured by the network device, whether the guaranteed bit rate (GBR) configured by the network device is effective, and the network load corresponding to the network device; the network device includes a first device and at least one second device.

[0095] It should be noted that the release version of the network device includes but is not limited to the version of the network communication standard supported by the cell corresponding to the device, such as R15, R16, and R17. It should be noted that when a high-version device switches to a low-version device, the low-version device does not support the capabilities of the relevant high-version device, which may cause the switching failure. Therefore, in this application, the first device pre-acquires the Release version of the second device, which can avoid the problem of the first terminal switching failure due to version problems.

[0096] In the embodiments of the present application, the network device slice resource reservation method and ratio, MinBR, PBR and network load are all used to characterize the resources currently available to the network device; if the network device corresponding to the neighboring cell to be switched / redirected / reselected by the first terminal currently has insufficient resources available, switching / redirection / reselection problems may also occur. Therefore, in the present application, the first device pre-acquires the device slice resource reservation method and ratio, MinBR, PBR and network load of the second device, which can avoid the problem of poor experience after the first terminal switches / redirects / reselects due to resource issues.

[0097] Step 204: During the movement of the first terminal, the first device assists the first terminal in switching or redirecting or reselecting the current resident cell of the first terminal based on the first information, the attribute information of the first device and the attribute information of the second device.

[0098] In an embodiment of the present application, during the movement of the first terminal, the device corresponding to the current cell of the first terminal, that is, the first device, can directly assist the first terminal in switching or redirecting or reselecting the current cell of the first terminal based on the acquired information, that is, the capabilities supported by the first terminal, and / or the contract information associated with the interoperability service in the first terminal, the attribute information of the device corresponding to the current cell of the first terminal, and the attribute information of the device corresponding to the neighboring cell; or, the first device can send the above-mentioned acquired information to other associated devices, and the other associated devices can assist the first terminal in switching or redirecting or reselecting the current cell of the first terminal based on the above-mentioned acquired information.

[0099] The present application discloses a communication method in a terminal mobility process, the method comprising: a first terminal sends first information of the first terminal to a first device; wherein the first information represents the capabilities supported by the first terminal, and / or the contract information associated with the interoperability service in the first terminal; the first device is a network device corresponding to the current resident cell of the first terminal. The first device receives the first information sent by the first terminal. The first device obtains attribute information of at least one second device. wherein the second device is a network device corresponding to a neighboring cell of the current resident cell of the first terminal. During the mobility of the first terminal, the first device assists the first terminal in switching or redirecting or reselecting the current resident cell of the first terminal based on the first information, the attribute information of the first device and the attribute information of the second device. That is to say, when the first terminal needs to switch / redirect / reselect a cell, the network device corresponding to the current resident cell of the first terminal, that is, the first device assists the first terminal in selecting an accessible neighboring cell through the terminal capabilities pre-reported by the first terminal and / or the contract configuration information associated with the interoperable service in the terminal, and the attribute information of the network devices corresponding to itself and the neighboring cell, such as the version of itself and the neighboring cell, thereby avoiding the first terminal from accessing a neighboring cell that cannot provide available resources for the first terminal, saving signaling resources. At the same time, the problem of consuming network resources due to the failure of the first terminal to switch / redirect / reselect is avoided.

[0100] In some embodiments, step 203, the first device obtaining attribute information of at least one second device, may be implemented through step 2031, or through step 2032, or through step 2033:

[0101] Step 2031: During the process of interaction between the first device and at least one second device through the first interface, obtain attribute information of the second device from the interaction information.

[0102] In the embodiment of the present application, the first device interacts with at least one second device, that is, the base station, through a direct interface. The interactive signaling includes but is not limited to a handover request and a handover request acknowledgment. The base stations can interact periodically or event-triggered, for example, when the content of certain fields in the neighboring area changes and affects the decision of interoperability, the base stations are triggered to interact through a direct interface.

[0103] Step 2032: During the process of interaction between the first device and at least one second device through the core network device, obtain attribute information of the second device from the interaction information.

[0104] In the embodiment of the present application, the first device and at least one second device, that is, the base station, are connected through the core network device, that is, Figure 1 The core network device 130 in the base station indirectly interacts. The interactive signaling includes but is not limited to handover required, handover request, handover request acknowledgement, handover command and hangover command. The base stations can interact periodically or event-triggered. For example, when the content of certain fields in the neighboring cell changes and affects the decision of interoperability, the base stations are triggered to interact indirectly through the core network device.

[0105] Step 2033: Obtain attribute information of the second device from the network management configuration information.

[0106] In the embodiment of the present application, the network management configures the relevant version, function support, parameter configuration and other information of the surrounding neighboring cells.

[0107] In some embodiments, the first device in step 204 assists the first terminal in switching or redirecting or reselecting the current resident cell of the first terminal based on the first information, the attribute information of the first device, and the attribute information of the second device, which can be implemented through steps A1 to A3, or through steps A4 to A9:

[0108] Step A1: The first device extracts keywords from the first information, the attribute information of the first device, and the attribute information of the second device to obtain a first key field corresponding to the first information, a second key field corresponding to the attribute information of the first device, and a third key field corresponding to the attribute information of the second device.

[0109] The keywords involved in the embodiments of the present application are fields that have substantial meaning for expressing the core content of the information. Exemplarily, the first device can extract keywords from the information using a term frequency-inverse document frequency (TF-IDF) algorithm based on natural language processing (NLP) technology.

[0110] Exemplarily, the obtained first key field includes but is not limited to the first terminal being a CAG only terminal, CAG 1, CAG 2, slice 1, and slice 2. The obtained second key field includes R17, 5G, and TA value is 1. The obtained second key field includes R16, 5G, and TA values ​​are 1 and 2.

[0111] Step A2: The first device takes the intersection of the first key field, the second key field and the third key field to obtain an intersection result.

[0112] In an embodiment of the present application, the first device takes the intersection of the first key field, the second key field and the third key field to obtain an intersection result, which is to aggregate the first key field and the second key field together to obtain a fourth key field; further, the intersection of the fourth key field and the third key field is taken to obtain an intersection result.

[0113] In an embodiment of the present application, the base station performs key field intersection processing on the information reported by the terminal, the information stored on the base station side (such as slice resource reservation method and ratio, MinBR / PBR, whether GBR is effective), and the information interacted between neighboring stations to obtain an intersection result.

[0114] Step A3: The first device assists the first terminal in switching or redirecting or reselecting the current resident cell of the first terminal based on the intersection result.

[0115] In an embodiment of the present application, if the intersection result indicates that there is a partial intersection among the first key field, the second key field and the third key field, then the cell corresponding to the second device can be used as a candidate cell; if the intersection result indicates that there is no intersection among the first key field, the second key field and the third key field, then the cell corresponding to the second device cannot be used as a candidate cell.

[0116] Step A4: The first device sends an access request to the second device.

[0117] Among them, the access request is used to notify the second device to access the first terminal to the cell corresponding to the second device; the access request includes first information representing the capabilities supported by the first terminal, and / or the contract information associated with the interoperability service in the first terminal and the attribute information of the first device.

[0118] In the embodiment of the present application, the access request may be a switching request, a redirection request, and a reselection request.

[0119] In the embodiments of the present application, the access request is sent in the following ways: in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0120] Step A5: The second device receives the access request sent by the first device.

[0121] It should be noted that after the second device receives the capabilities supported by the first terminal, and / or the first information of the contract information associated with the interoperability service in the first terminal and the attribute information of the first device, during the movement of the first terminal, the second device assists the first terminal in switching or redirecting or reselecting the current resident cell of the first terminal based on the first information, the attribute information of the first device and the attribute information of the second device.

[0122] Step A6: The second device extracts keywords from the first information, the attribute information of the first device, and the attribute information of the second device to obtain a first key field corresponding to the first information, a second key field corresponding to the attribute information of the first device, and a third key field corresponding to the attribute information of the second device.

[0123] The keywords involved in the embodiments of the present application are fields that have substantial meaning for describing the core content of the information. Exemplarily, the second device can extract keywords from the information based on the TF-IDF algorithm of the NLP technology.

[0124] Step A7: The second device takes the intersection of the first key field, the second key field and the third key field to obtain an intersection result.

[0125] In an embodiment of the present application, the second device takes the intersection of the first key field, the second key field and the third key field to obtain an intersection result, which is to aggregate the first key field and the second key field together to obtain a fourth key field; further, the intersection of the fourth key field and the third key field is taken to obtain an intersection result.

[0126] Step A8: When the intersection result indicates that the first key field, the second key field and the third key field have no intersection, the second device sends an access rejection message to the first device.

[0127] The access rejection message is used to prohibit the first terminal from accessing the cell corresponding to the second device.

[0128] In the embodiment of the present application, the method of sending the access rejection message includes: in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0129] Step A9: The first device receives an access rejection message sent by the second device.

[0130] In an embodiment of the present application, the first device, i.e., the source base station, sends the key information reported by the first terminal, the key information stored on the base station side, i.e., the capabilities supported by the first terminal, and / or the contract information associated with the interoperability service in the first terminal, and the attribute information of the first device to the neighboring station, i.e., the second device, in an access request. The second device performs intersection processing. If the intersection is empty, it replies with a switching rejection to avoid switching failure.

[0131] In some embodiments, the first device in step A3 assists the first terminal in switching or redirecting or reselecting the current resident cell of the first terminal based on the intersection result, which can be implemented through steps B1 to B7, or through steps B8 to B14, or through steps B8 to B12, and steps B15 to B17:

[0132] Step B1: when the intersection result indicates that the first key field, the second key field and the third key field have no intersection, the first device deletes the measurement configuration information corresponding to the cell corresponding to the second device in the first measurement configuration information to obtain second measurement configuration information.

[0133] The first measurement configuration information includes information of at least one candidate cell that the first terminal can access.

[0134] In the embodiment of the present application, the information of at least one candidate cell includes an identifier of at least one candidate cell.

[0135] Step B2: The first device sends second measurement configuration information to the first terminal.

[0136] In the embodiment of the present application, the second measurement configuration information is sent in the following ways: in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0137] Step B3: The first terminal receives second measurement configuration information sent by the first device.

[0138] Step B4: The first terminal measures the performance of the candidate cell in the second measurement configuration information to obtain a first measurement result.

[0139] In the embodiment of the present application, the performance of the candidate cell includes parameters of the signal quality of the candidate cell, where the signal quality parameters may include but are not limited to one or more of the following: RSRP, RSSI, RSRQ, RSL.

[0140] Step B5: The first terminal sends the first measurement result to the first device.

[0141] In the embodiment of the present application, the first measurement result is sent in an in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0142] Step B6: The first device receives the first measurement result sent by the first terminal.

[0143] Step B7: The first device assists the first terminal in switching, reselecting or redirecting the current resident cell of the first terminal based on the first measurement result.

[0144] In the embodiment of the present application, the source base station and the first device remove the information of the neighboring area from the measurement configuration information of the terminal of this type to avoid the failure of switching and redirection. Here, the terminal of this type includes a terminal with the same terminal capability and / or the same configuration as the first terminal.

[0145] Exemplarily, the first terminal is a 4G / 5G dual-mode terminal, which only supports the RedCap mode under the 5G standard and is configured as a CAGonly terminal, and the subscribed CAG ID is 1; all surrounding 2.6G frequency neighboring cells are R16 version 5G base stations (RedCap is not supported), which are non-CAG only cells, and the subscribed CAG IDs are 2 and 3. The terminal information, self-information and neighboring cell information exchanged between base stations are processed by taking the intersection, and the intersection is empty. Therefore, it is necessary to exclude the neighboring cell in the measurement configuration message or radio resource control (RRC) release (Release) message of this type of terminal (same UE capability, same configuration). When only NR neighbor cells other than 2.6G are configured in the RRC measurement configuration message (MeasConfig information element-MeasObjectToAddModList-MeasObjectNR), or the capability and configuration information of the surrounding neighbor cells are received only after the source cell sends the measurement configuration to the terminal, the 2.6G measurement configuration is removed through the RRC measurement configuration message (MeasConfig informationelement-MeasObjectToRemoveList). If the capabilities or configurations of different neighbor cells on the 2.6G frequency point are different, the corresponding cell ID can be removed through the RRC measurement configuration message (MeasConfig information element-MeasObjectToAddModList-MeasObjectNR-cellsToRemoveList).

[0146] Step B8: The first device sends first measurement configuration information to the first terminal.

[0147] The first measurement configuration information includes information of at least one candidate cell that the first terminal can access.

[0148] In the embodiment of the present application, the first measurement configuration information is sent in the following ways: in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0149] Step B9: The first terminal receives first measurement configuration information sent by the first device.

[0150] Step B10: The first terminal measures the performance of the candidate cell in the first measurement configuration information to obtain a second measurement result.

[0151] Step B11: The first terminal sends the second measurement result to the first device.

[0152] In the embodiment of the present application, the second measurement result is sent in an in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc.

[0153] Step B12: The first device receives the second measurement result sent by the first terminal.

[0154] Step B13: When the intersection result indicates that the first key field, the second key field and the third key field have no intersection, the first device deletes the measurement result corresponding to the cell corresponding to the second device in the second measurement result to obtain a third measurement configuration result.

[0155] Step B14: The first device assists the first terminal in switching, reselecting or redirecting the current resident cell of the first terminal based on the third measurement result.

[0156] In the embodiment of the present application, the source base station, i.e., the first device, removes the neighboring cell information after receiving the measurement result report of the terminal of this type, and does not initiate a handover request to the neighboring cell, thereby avoiding handover failure. Here, the terminal of this type includes a terminal with the same terminal capability and / or the same configuration as the first terminal.

[0157] Step B15: When the intersection result indicates that the first key field, the second key field and the third key field have no intersection, and the first terminal meets the redirection condition, the first device sends a redirection message to the first terminal.

[0158] The redirection message includes a blacklist cell field that the first terminal is prohibited from accessing, and the blacklist cell field includes a field corresponding to a cell corresponding to the second device.

[0159] In the embodiment of the present application, the first terminal meets the redirection condition including that the distance between the first terminal and the first device meets the preset distance condition; the forward link quality and reverse link quality of the first terminal on the heterofrequency carrier frequency of the network meet the redirection condition.

[0160] Step B16: The first terminal receives the redirection message sent by the first device.

[0161] Step B17: The first terminal redirects the current cell where the first terminal resides to the target cell based on the redirection message.

[0162] The target cell is a cell other than the cell corresponding to the second device in the candidate cells in the first measurement configuration information.

[0163] In an embodiment of the present application, after the first device receives the measurement result report of this type of terminal, it removes the neighboring area information from the redirection message sent to the terminal, such as the RRC Release message, RRC Resume message and RRC Reconfiguration message, to avoid redirection failure.

[0164] The following blacklist cell field is added to the redirection message of RRC release, and all neighboring cells whose intersection with the terminal is empty are put into the blacklist cell field to prevent the terminal from being redirected to these neighboring cells.

[0165] Exemplarily, the neighboring cells in the same frequency blacklist are put into IntraFreqBlackCellList, and the neighboring cells in the different frequency blacklist are put into InterFreqBlackCellList.

[0166] intraFreqBlackCellList IntraFreqBlackCellList

[0167] interFreqBlackCellList InterFreqBlackCellList

[0168] IntraFreqBlackCellList::= SEQUENCE(SIZE(1..maxCellBlack))OF PCI-Range / / Blacklist neighboring cells in the same frequency

[0169] InterFreqBlackCellList::=SEQUENCE(SIZE(1..maxCellBlack))OF PCI-Range / / Inter-frequency blacklist neighboring cell list

[0170] The above is a system information block (SIB) message, and the SIB message includes information on reselection of a same-frequency blacklist cell and information on reselection of a different-frequency blacklist cell.
