[0036] 5G AP is introduced into the wireless communication system for indoor coverage. Therefore, after the introduction of 5G AP, the study of paging mechanism has important practical value for improving network performance.

[0037] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0038] The term "and / or" in this application is only a description of the association relationship of 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 indicates that the associated objects before and after are in an "or" relationship.

[0039] At least one in the embodiments of the present application refers to one or more. "Multiple" refers to two or more. The first, second, etc. descriptions appearing in the embodiments of the present application are only used for illustration and distinction of the described objects. There is no order, nor does it represent a special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application. The "connection" appearing in the embodiments of the present application refers to various connection methods such as direct connection or indirect connection to achieve communication between devices, and the embodiments of the present application do not impose any limitations on this.

[0040] The embodiments of the present application can be applied to NR communication systems, or next generation wireless communication systems, etc., without limitation. Figure 1 , which is a network architecture diagram of a communication system according to an embodiment of the present application. As shown in the figure, the communication system includes a terminal 111, a terminal 112, a terminal 113, a terminal 114, an access point device 121, an access point device 122, an access point device 123, an access network device 130, and a core network device 140.

[0041] For example, the terminal 111 can communicate directly with the access network device 130. For another example, the terminal 112 can access the network through the access point device 121, and the access point device 121 is connected to the access network device 130. For another example, the access point device 122 is connected to the access network device 130. In some embodiments, the access point device 122 can also be connected to the core network device 140. In the case where the access point device 122 is connected to the access network device 130 and the core network device 140 at the same time, the core network device 140 can communicate directly with the access point device 122, and can also communicate with the access point device 122 through the access network device 130. The specific path through which the core network device 140 communicates with the access point device 122 can be pre-configured or determined according to a certain policy, and there is no limitation on this. For another example, the access point device 123 is connected to the core network device 140.

[0042] Figure 1 This is only an example of a communication system, and the embodiments of the present application do not limit this. For example, the embodiments of the present application do not limit the number of access point devices, the number of terminals, the number of access network devices, the number of core network devices, etc. in the communication system.

[0043] The terminal in the embodiments of the present application may refer to various forms of UE, access terminal, user unit, user station, mobile station, MS (English: mobile station, Chinese: mobile station), remote station, remote terminal, mobile device, user terminal, terminal equipment (English: terminal equipment), wireless communication equipment, user agent or user device. The terminal equipment may also be a cellular phone, a cordless phone, a SIP (English: session initiation protocol, Chinese: session initiation protocol) phone, a WLL (English: wireless local loop, Chinese: wireless local loop) station, a PDA (English: personal digital assistant, Chinese: personal digital processing), 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 future 5G network or a terminal device in a future evolved PLMN (English: public land mobile network, Chinese: public land mobile communication network), etc., and the embodiments of the present application are not limited to this.

[0044] The access network device in the embodiment of the present application may be a device that provides an interface for a terminal or access point device to access a communication network. For example, the access network device may be a base station, such as a 5G base station, a gNB (generation NodeB), or a base station in a next-generation wireless communication system, etc., without limitation.

[0045] The access point device in the embodiment of the present application can be a device that provides an interface for a terminal to access an access network device or a core network device. An example access point device can be an AP (Access Point), for example, a 5G AP, a H(e)NB, etc.

[0046] It should be noted that, in the embodiment of the present application, the coverage of the access point device is relatively small compared to the coverage of the access network device. In the embodiment of the present application, the cell of the access network device can be referred to as a macro cell. The cell of the access point device can include the following types: open cell, closed cell, hybrid cell, which can be customized by the user according to his own needs or pre-configured before the access point device leaves the factory, and there is no limitation on this.

[0047] For example, for an open cell, all terminals accessed through access point devices are billed separately;

[0048] For mixed cells or closed cells, password authorization can be used without separate billing. For example, for access point devices deployed in restaurants and hotels, customers can enter the corresponding password on the terminal so that the terminal can access the corresponding access point device without separate billing for the terminal. Or for access point devices deployed in private clinics, customers can enter the corresponding password on the terminal device so that the terminal can access the corresponding access point device, but the customer's terminal needs to be billed separately, while the terminals of doctors or other staff, or other authorized users, do not need to be charged extra. Or, for access point devices deployed in the home, there is no need to pay extra for the terminals of family members to access the access point device. Family members can tell visitors the password, and visitors enter the corresponding password on the terminal to access the access point device without additional charges.

[0049] The core network device in the embodiment of the present application is used for the mobility management of the terminal. For example, in the embodiment of the present application, the core network device may be a mobility management device, such as an access and mobility management function (AMF) network element.

[0050] Example 1: The access point device is connected to the core network device through the access network device. When paging a terminal (hereinafter taking terminal 1 as an example), the core network device indicates to the access network device the access point device to receive the paging message for paging terminal 1. This helps reduce the possibility of the access point device sending irrelevant paging messages.

[0051] like Figure 2A As shown, a paging method according to an embodiment of the present application specifically includes the following steps:

[0052] S200A. The core network device sends a paging message 1 to the access point device. The paging message 1 is used to page terminal 1.

[0053] For example, the paging message 1 includes paging association information, where the paging association information is used to indicate at least one access point device. The at least one access point device is associated with the terminal 1 .

[0054] It should be noted that at least one access point device associated with terminal 1 can be understood as: at least one access point device authorized to be accessed by terminal 1. The at least one access point device authorized to be accessed by terminal 1 can be all node devices authorized to be accessed by terminal 1, or can be part of the access point devices accessed by terminal 1.

[0055] In some embodiments, the paging-related information may include any one or any combination of the following:

[0056] Closed user group list, first indication information, access point association identifier.

[0057] For example, in an embodiment of the present application, a closed user group list is used to indicate a cell that terminal 1 is allowed to access. For example, the closed user group list may be a cell identifier list, wherein the cell identifier list includes at least one cell identifier, and each cell identifier is used to identify a cell of an access point device that terminal 1 is allowed to access. For example, the cell identifier list may also be referred to as a closed subscriber group (CSG) ID list, a private user group (PUG) ID list, etc., without limitation. In this case, the access network device may determine at least one access point device according to the closed user group list.

[0058] For example, at least one cell identifier in the closed user group list may correspond to a user group identifier, and the user group identifier corresponds to a terminal identifier. The user group identifier is used to identify a closed user group list, and the terminal identifier corresponding to the user group identifier is used to identify the terminal to which the closed user list belongs.

[0059] For example, in the embodiment of the present application, allowing terminal 1 to access an access point device can be understood as: allowing terminal 1 to establish a connection with an access point device, and / or allowing terminal 1 to reside on an access point device.

[0060] In the embodiment of the present application, the first indication information is used to indicate a cell that terminal 1 preferentially accesses. In the embodiment of the present application, the first indication information is used to indicate a cell that terminal 1 preferentially accesses. In the embodiment of the present application, the cell of the access point device refers to a cell that the access point device uses to provide services.

[0061] In the embodiment of the present application, by way of example, an access point association identifier is used to indicate a cell of at least one access point device. For example, the access point association identifier may be indicated by a cell group identifier, or by other means, without limitation. By way of example, the access point association identifier is associated with at least one device identifier, or at least one cell identifier. It should be noted that the device identifier associated with the access point association identifier is used to identify the access point device, and the cell identifier associated with the access point association identifier is used to identify the cell of the access point device.

[0062] Or, as another example, the paging association information includes at least one device identifier, and each device identifier is used to identify an access point device.

[0063] It should be understood that the above is merely an example of a specific implementation method of paging-related information, and the embodiments of the present application do not limit this.

[0064] The above-mentioned paging-related information can be obtained by the core network device based on the subscription information and / or authorization information of the access point device, which is described in detail below and will not be repeated here.

[0065] S201A: The access network device receives paging message 1 and sends paging message 2 to at least one access point device according to paging association information. Paging message 2 is used to page terminal 1.

[0066] Step 202A: The access point device receives the paging message 2 and sends the paging message 3 to the terminal 1 to implement paging for the terminal 1 .

[0067] The technical solution provided by the present application helps to reduce the number of paging messages sent, meet the requirements of AP deployment, and improve network performance because the core network device can indicate at least one access point device to the access network device, so that the access network device can only send paging messages to at least one access point device indicated by the core network device.

[0068] Further, in some embodiments, when the access point device fails to page the terminal 1, feedback is given to the access network device, and when all access point devices fail to page the terminal 1, the access network device continues to page the terminal 1 in the macro cell. The macro cell is a cell of the access network device, which is used to provide services for the terminal 1.

[0069] In some other embodiments, the core network device may not send the paging-related information to the access network device, or the paging-related information is empty.

[0070] Taking the paging-associated information as a closed user group list as an example, in some embodiments, if the closed user group list is empty, the core network device may only send a paging message for paging terminal 1 to the access network device. After the access network device receives the paging message from the core network device, it pages terminal 1 within the cell (i.e., macro cell) of the access network device, and the access network device does not send a paging message to the access point device.

[0071] Alternatively, in some other examples of the present application, if the closed user group list is empty, the core network device may only send a paging message for paging terminal 1 to the access network device. After receiving the paging message from the core network device, the access network device pages terminal 1 in the cell of the access network device (i.e., the macro cell). If the access network device fails to page terminal 1, it pages terminal 1 in the cell of the access point device. For example, in this case, the access point device is located within the coverage area of ​​the cell of the access point device. Specifically, in an embodiment of the present application, if the access network device fails to page terminal 1 in the macro cell, it may page terminal 1 in the cells of one or more access point devices. For example, if the access network device fails to page terminal 1 in the macro cell, the access network device may send a paging message for paging terminal 1 to all access point devices within the coverage area of ​​the macro cell, so that the access point device pages terminal 1.

[0072] In some embodiments of the present application, the access point device may also send cell type indication information to the access network device, where the cell type indication information is used to indicate the cell type of the access point device, such as closed, open or mixed, so that the access network device can obtain the cell type of the access point device.

[0073] For example, the access point device reports the cell type indication information to the access network device, and the access network device reports the cell type indication information to the core network device.

[0074] To simplify the description, a cell whose cell type is closed is referred to as a closed cell, and a cell whose cell type is mixed is referred to as a mixed cell.

[0075] When the access network device (or core network device) detects that the hybrid cell or closed cell of the access point device allows a terminal (for example, terminal 2) to access, the corresponding paging association information is updated according to the cell association information of the hybrid cell or closed cell. Take the paging association information as a CUG ID list as an example. The cell association information is used to indicate the user group to which the cell belongs. For example, if the cell association information is used to indicate that the user group identifier of the user group to which the cell belongs is user group identifier 1, the access network device (or core network device) can add the cell identifier of the hybrid cell or closed cell to the CUG ID list corresponding to the user group identifier 1 and the terminal identifier of terminal 2.

[0076] For example, the cell association information may be configured by the operator or reported by the access point device or the terminal. For example, in the case where the access point device or the terminal 2 reports, the cell association information may be set by the user. For example, when the access point device receives a cell authorization request from the terminal 2, the cell authorization request includes password 1, that is, the password entered by the user on the terminal 2. After the access point device verifies the password 1, it prompts the user to set the cell association information, and after the user completes setting the cell association information, it reports the cell association information to the core network device or the access network device.

[0077] The above is only an example of configuring the cell association information. The embodiment of the present application can also configure the cell association information in other ways, which is not limited to this.

[0078] Further, in some embodiments, if the terminal 1 detects that the mobile is out of the coverage of the closed cell or the hybrid cell for more than the first duration, the mobile registration process is triggered, and the core network device (or access network device) is requested to delete the paging association information for identifying the corresponding access point device. For example, the first duration can be predefined by the communication protocol or determined according to a certain policy, which is not limited.

[0079] Alternatively, terminal 1 sends a cell authorization request to the access point device, and the cell authorization request includes password 1, which is the password entered by the user. After receiving the cell authorization request from terminal 2, the access point device verifies password 1 and returns a cell authorization response to terminal 1. The cell authorization response is used to indicate authorization of terminal 1. After receiving the cell authorization response, terminal 1 prompts the user to set cell association information, and after the user completes setting the cell association information, the cell association information and cell authorization information are reported to the access point device.

[0080] Among them, the cell authorization information is the authorization information of terminal 1. For example, the authorization information of terminal 1 may include: the identifiers of all authorized closed user group cells of the terminal 1, or the identifier of the closed user group cell currently accessed by the terminal 1, or the identifier of the new closed user group cell of the terminal 1 (i.e., the identifier of the closed user group cell that has not been reported). The above-mentioned cell association information may include: an indication of whether the closed user group cell is authorized, for example, when the cell association information is represented by an identification bit, 1 may represent authorization, 0 may represent unauthorization, and if there are multiple closed user group cells, it may be represented by a bitmap. It should be understood that the closed user group cell includes the closed cell and / or hybrid cell of the access point device.

[0081] The following is an actual example to illustrate the authorization information of terminal 1. For example, terminal 1 has the identifiers of three authorized closed user group cells, which may be CUG1, CUG2, and CUG3 respectively. Terminal 1 can report CUG1, CUG2, and CUG3; if the identifier of the currently accessed closed user group cell is CUG2, terminal 1 can also report CUG2. If terminal 1 reports CUG1 and CUG2 before accessing CUG3, but CUG3 is not reported, terminal 1 can report CUG3.

[0082] In addition, when the paging association information includes the access point association identifier, the access network device (or core network device) may also configure the access point association identifier for the access point device according to the subscription information of the access point device.

[0083] For example, when the contract information of different access point devices is used to indicate the same organization or address, the access point association identifiers configured by the access network device (or core network device) for the different access point devices are the same. For example, the access network device (or core network device) can configure the access point association identifier for the access point device by establishing a correspondence or mapping relationship between the cell identifier of the access point device and the access point association identifier.

[0084] Alternatively, in some embodiments, the access network device (or core network device) configures an access point association identifier for the access point device according to the location information of the access point device.

[0085] For example, the access point association identifiers configured for different access network devices located in the first area are the same. For example, the access point association identifier may be a location area identifier, such as a tracking area identifier (Tracking Area Identity), and the first area may be a tracking area. Alternatively, the access point association identifier may be other identifiers, and the first area may also be a RAN area, etc., which is not limited thereto.

[0086] For example, when the location of the access point device moves, the mobile registration process can be triggered to update the access point association identifier of the access point device. For example, when the access point device moves from a first area to a second area, the access network device (or core network device) needs to update the access point association identifier of the access point device to the access point association identifier corresponding to the second area.

[0087] Alternatively, in some other embodiments, the access network device (or core network device) configures the same access point association identifier for at least one access point device according to the specific identifier reported by the access point device. For example, the specific identifier reported by at least one access point device configured with the same access point association identifier is the first identifier. For example, the specific identifier may be reported during the registration process or reported by other processes, which is not limited.

[0088] Further, in some embodiments, the access point association identifier configured for at least one access point device corresponds to a first terminal identifier list, and the first terminal identifier list is used to indicate terminals that are allowed to access a cell of at least one access point device. Take the first terminal identifier list including terminal identifier 1 and terminal identifier 2 as an example. Terminal identifier 1 is used to identify terminal 1, and terminal identifier 2 is used to identify terminal 2; in this case, if the core network device receives a context from terminal 2, the context of terminal 2 is used to indicate that terminal 2 is not within the service range of the cell of at least one access point device; then the access network device (or core network device) deletes terminal identifier 2 in the first terminal identifier list, that is, stops authorizing terminal 2.

[0089] In some embodiments, when the terminal 1 detects that it has entered the first area, it reports first information to the access network device or the core network device, where the first information is information of the access point device, which is used to indicate the access point device or the cell of the access point device. For example, the first area can be the coverage range of the cell of the access point device 1.

[0090] For example, when the terminal 1 is turned on, it detects that it is in the first area and reports the first information to the access network device. For another example, when the terminal 1 moves from the second area to the first area, it reports the first information to the access network device. The second area can be the coverage of the cell of the access point device 2.

[0091] However, the coverage of the cell of the access point is usually small, and the terminal may enter or leave for a short time. Therefore, taking terminal 1 as an example, terminal 1 may send first information to the access network device after moving into the first area for a first time period, and the first information is used to indicate that terminal 1 resides in the cell of access point device 1. This helps to reduce the possibility of frequent mobile registration of the terminal.

[0092] For example, the first information may be a cell identifier of the access point device 1, or a device identifier of the access point device 1, etc. The first duration is the minimum duration for the authorized terminal 1 to access the cell of the access point device and stay in the first area, which may be predefined by a protocol or indicated to the terminal device by the access network device, for example, the value of the first duration may be 15 minutes, 30 minutes, etc.

[0093] Taking the first duration as an indication from the access network device to the terminal device as an example, the access network device may send indication information 1 to the terminal 1, where the indication information 1 is used to indicate the first duration.

[0094] Alternatively, in some embodiments, after moving into the first area, the terminal 1 may send the first information to the access network device after detecting that the network quality of the cell of the access point device 1 is better than the network quality of the serving cell for a second period of time, thereby helping to further reduce the possibility of frequent mobile registration of the terminal.

[0095] For example, the second duration may be predefined or may be indicated by the access network device to the terminal 1, and this is not limited. For example, the access network device may send indication information 2 to the terminal 1, and the indication information 2 is used to indicate the second duration. The second duration may also be referred to as the cell reselection delay, and this is not limited in the embodiments of the present application.

[0096] Example 2: The access point device is connected to the core network device. When paging a terminal (hereinafter, terminal 1 is taken as an example), the core network device sends a paging message to the access point device associated with terminal 1. This helps reduce the possibility of the access point device sending irrelevant paging messages.

[0097] like Figure 2B FIG. 1 is a flow chart of a paging method according to an embodiment of the present application, which specifically includes the following steps:

[0098] S200B: The core network device sends a paging message 1 to at least one access point device according to the paging association information, where the paging message 1 is used to page terminal 1. The paging association information is used to indicate at least one access point device.

[0099] In some embodiments, the core network device obtains paging association information, and then sends a paging message to at least one access point device according to the paging association information.

[0100] For example, the core network device may send a paging message 1 to at least one access point device according to paging association information in response to a certain triggering event; for example, a certain triggering event may be that another terminal paging terminal 1. Alternatively, the core network device may also periodically send a paging message 1 to at least one access point device according to paging association information. The embodiment of the present application does not limit the manner in which the core network triggers the sending of a paging message 1 to at least one access point device according to paging association information.

[0101] For the relevant introduction of paging-related information, please refer to the relevant introduction in S200A, which will not be repeated here.

[0102] Step S201B: The access point device receives the paging message 1 from the core network device, and sends the paging message 2 to implement paging for the terminal 1 .

[0103] Furthermore, in some embodiments, when the access point device fails to page terminal 1, feedback is given to the core network device. When all access point devices fail to page terminal 1, the core network device sends a paging message for paging terminal 1 to the access network device, and the access network device continues to page terminal 1 in the macro cell.

[0104] Alternatively, in some other embodiments of the present application, the paging association information may be empty. In this case, the core network device may send a paging message for paging terminal 1 to the access network device, so that the access network device pages terminal 1 in the macro cell and no longer sends a paging message for paging terminal 1 to the access point device. Alternatively, in the case where the paging association information may be empty or the paging association information is used to indicate that paging in the macro cell is preferred, the core network device may first send a paging message for paging terminal 1 to the access network device, and if the access network device fails to page terminal 1, the core network device then sends a paging message for paging terminal 1 to one or more access point devices managed by it.

[0105] Alternatively, when the paging association information may be empty or the paging association information is used to indicate priority paging in the cell of the access point device, the core network device may also send a paging message for paging terminal 1 to one or more managed access point devices. Further, in some embodiments, the core network device may also send a paging message for paging terminal 1 to the access network device when the access point device fails to page terminal 1, so that the access network device pages terminal 1 in the macro cell.

[0106] In some embodiments of the present application, the access point device may also send cell type indication information to the core network device, where the cell type indication information is used to indicate the cell type of the access point device, such as closed, open or mixed, so that the core network device can obtain the cell type of the access point device.

[0107] To simplify the description, a cell whose cell type is closed is referred to as a closed cell, and a cell whose cell type is mixed is referred to as a mixed cell.

[0108] When the core network device detects that the hybrid cell or closed cell of the access point device allows a terminal (for example, terminal 2) to access, the core network device updates the corresponding paging association information according to the cell association information of the hybrid cell or closed cell. Take the paging association information as a CUG ID list as an example. The cell association information is used to indicate the user group to which the cell belongs. For example, if the cell association information is used to indicate that the user group identifier of the user group to which the cell belongs is user group identifier 1, the core network device can add the cell identifier of the hybrid cell or closed cell to the CUG IDlist corresponding to the user group identifier 1 and the terminal identifier of terminal 2.

[0109] Specifically, for the cell association information, please refer to the relevant description in Example 1, which will not be repeated here.

[0110] In some embodiments, when the terminal 1 detects that it has entered the first area, it reports first information to the core network device, where the first information is information of the access point device, which is used to indicate the access point device or the cell of the access point device. For the first area, please refer to the relevant description in Example 1.

[0111] However, the coverage of the cell of the access point is usually small, and the terminal may enter or leave for a short time. Therefore, taking terminal 1 as an example, terminal 1 may send first information to the core network device after moving into the first area for a first time period, and the first information is used to indicate that terminal 1 resides in the cell of access point device 1. This helps to reduce the possibility of frequent mobile registration of the terminal.

[0112] Regarding the first information and the first duration, please refer to the relevant description in Example 1 and will not be repeated here.

[0113] Alternatively, in some embodiments, after moving into the first area, the terminal 1 may send the first information to the core network device after detecting that the network quality of the cell of the access point device 1 is better than the network quality of the serving cell for a second period of time, thereby helping to further reduce the possibility of frequent mobile registration of the terminal.

[0114] For the second duration, please refer to the relevant description in Example 1, which will not be repeated here.

[0115] In addition, the present application embodiment also provides a paging method, such as Figure 3 As shown, the following steps are included:

[0116] S301, the terminal detects that it has entered a first area, where the first area is a coverage area of ​​a cell of a first access point device;

[0117] The specific implementation method of the above terminal detecting entering the first area can refer to the above Figure 2A The description of the illustrated embodiment will not be repeated here.

[0118] S302: The terminal reports first information to a network device, where the first information is used to indicate a cell of a first access point device, or the first information is used to indicate a first access point device. It should be noted that the network device in S302 may be a core network device or an access network device.

[0119] like Figure 3 The paging method in the illustrated embodiment supports the following Figure 2A or Figure 2B Implementation of the method of the illustrated embodiment improves network performance.

[0120] In some examples, the coverage of the cell of the access point is usually small, and the terminal may enter or leave for a short time. Therefore, taking terminal 1 as an example, terminal 1 may send first information to a network device (such as a core network device, an access network device) after moving into the first area for a first time period. The first information is used to indicate that terminal 1 resides in the cell of access point device 1. This helps reduce the possibility of frequent mobile registration of the terminal.

[0121] Alternatively, in some embodiments, after moving into the first area, the terminal 1 may send the first information to the access network device after detecting that the network quality of the cell of the access point device 1 is better than the network quality of the serving cell for a second period of time, thereby helping to further reduce the possibility of frequent mobile registration of the terminal.

[0122] For the first information, the first duration, the second duration, etc., please refer to the relevant description in Example 1 and will not be repeated here.

[0123] Example 3: The access point device is connected to the core network device. When paging a terminal (hereinafter, terminal 1 is taken as an example), the core network device sends a paging message to the access point device associated with terminal 1. This helps reduce the possibility of the access point device sending irrelevant paging messages.

[0124] In some examples, the above method may further include:

[0125] The terminal device reports the authorization information and closed user cell association information of the terminal device to the network device; the authorization information of the terminal device is used to indicate that the terminal device is allowed to access the cell of the access point device, and the closed cell association information is used to indicate the association relationship between the cell of the access point device and the user group.

[0126] The definition of the authorization information of the above terminal equipment and the closed cell association information can be found in Figure 2A The relevant description of the illustrated embodiment will not be repeated here.

[0127] Example 4: Figure 4B Taking the network architecture shown in FIG. 1 as an example, the paging method of the embodiment of the present application is introduced. Figure 4B As shown, it is a network architecture diagram of a communication system of Example 4 of this application. Figure 4B As shown, the communication system may include: a macro base station (Macro gNB), an access point (5G AP) and a UE, wherein the 5G AP may be a privately deployed AP, the area coverage corresponding to the Macro gNB may be called a macro cell (Macro cell), and the area coverage corresponding to the 5G AP may be called a private user group cell (PUG cell). In Example 4, the UE moves from the macro cell to the private user group cell.

[0128] For example, Figure 4A As shown, a schematic diagram of a paging method is provided in an embodiment of the present application, which specifically includes the following steps:

[0129] S401. The 5G AP reports the type of the defined cell to the network device;

[0130] The above network equipment may specifically be an access network equipment, which may specifically be Figure 4B Macro gNB in.

[0131] S402, the network device updates the CUG (Closed User Group) cell list of the UE;

[0132] The above-mentioned updating methods may specifically include:

[0133] Synchronous authorization information method: In this method, the authorization information of the UE is synchronized to the network, and the network equipment can obtain relevant information. For example, the authorization and CUG cell association information can be stored in the UE context.

[0134] Cryptography: After the UE resides in a CUG cell authorized by the cryptography method, it triggers the mobile registration process and feeds back the CUG information and authorization information to the network, so that the network can save the UE's CUG information to improve the UE's CUGlist. The deletion of this type of CUG cell can be controlled by a timer. For example, when the UE leaves this type of CUG cell for a certain period of time, the mobile registration process is triggered, requesting the network to delete the storage of this type of CUG information.

[0135] S403. The network device obtains a paging message, which carries the CUG list of the UE. The network device forwards the paging message to the 5G AP in the CUGlist. The paging message is used to page the UE.

[0136] In the technical solution provided by the present application, a network device obtains paging association information, and the paging association information is used to determine a paging associated access point device; the network device sends a paging message to the paging associated access point device, so that the network device only sends a paging message to the paging associated access point, avoiding forwarding paging messages to CUG cells that are not in the UE's CUG list, meeting the requirements of AP deployment, and improving network performance.

[0137] Example 5: Take the access point device as 5G AP and the terminal as UE as an example.

[0138] The present application embodiment provides a paging method, such as Figure 5 As shown, the AP in the embodiment of the present application may be a 5G AP, comprising the following steps:

[0139] S501: The network device obtains a paging message, where the paging message includes indication information.

[0140] The indication information is used to instruct the UE to monitor paging messages only in the macro cell (reside only in the macro cell), or the UE preferentially resides in the macro cell, or the UE preferentially resides in the cell defined by the 5G AP.

[0141] The above network equipment may be different network equipment according to different network architectures, for example, it may be an access network equipment or a core network equipment.

[0142] S502: The network device sends a paging message to the corresponding access point device according to the indication information.

[0143] Specifically, they may include:

[0144] If the indication information indicates that the user equipment monitors the paging message only in the macro cell, the network device sends a paging message to the macro cell to page the user equipment;

[0145] If the indication information indicates that the user equipment preferentially resides in the macro cell, the network device preferentially sends a paging message to the macro cell to page the user equipment, and if the user equipment is not paged, sends a paging message in the cell of the access point device to page the user equipment;

[0146] If the indication information indicates that the user equipment preferentially resides in the cell of the access point device, the network device preferentially sends a second paging message in the cell of the access point device to page the user equipment, and if the user equipment is not paged, sends a paging message in the macro cell to page the user equipment;

[0147] If the paging association information is empty information; the network device preferentially sends the paging message to the user equipment in the macro cell, and if the user equipment is not paged, the network device sends the paging message to the user equipment in the cell of the access point device; or the network device preferentially sends the paging message to the user equipment in the cell of the access point device, and if the user equipment is not paged, the network device sends the paging message to the user equipment in the macro cell.

[0148] The technical solution provided by the present application is that the network device obtains paging association information, and the paging association information is used to determine the paging association access point device; the network device sends a paging message to the paging association access point device, so that the network device sends a paging message based on the indication information, thereby avoiding forwarding the paging message to the CUG cell that does not match the indication information, meeting the requirements of AP deployment, and improving network performance.

[0149] Example 6: The paging message includes an access point association identifier, and the method for determining the access point association identifier may specifically include: the network device determines the associated access point device based on the contract information of the access point device, and configures the same access point association identifier for the associated access point device; or the network device determines the associated access point device based on the location information of the access point device, and configures the same access point association identifier for the associated access point device; or the network device determines the associated access point device based on the area indication information carried by the access point device, and configures the same access point association identifier for the associated access point device.

[0150] The network equipment here can be a core network equipment or an access network equipment.

[0151] by Figure 6B Taking the network architecture shown in the figure as an example, a paging method provided by the embodiment of the present application is introduced. Figure 6B As shown, it is a network architecture diagram of a communication system of Example 6 of this application. Figure 6B As shown, the communication system may include: a macro base station (Macro gNB), access point 1 (5G AP1), access point 2 (5G AP2), access point 3 (5G AP3) and UE, wherein 5G AP1, 5G AP2 and 5G AP3 can all be privately deployed APs, the area coverage corresponding to the Macro gNB can be called a macro cell (Macro cell), the area coverage corresponding to 5G AP1 can be called a closed user group cell 1 (CUG cell1), the area coverage corresponding to 5G AP2 can be called a closed user group cell 2 (CUG cell2), and the area coverage corresponding to 5G AP3 can be called a closed user group cell 3 (CUG cell3). In Example 6, 5G AP1, 5G AP2 and 5G AP3 are geographically close. In Example 6, the UE is located in the macro cell and can move to any closed user group cell.

[0152] For example, Fig. 6A FIG. 1 is a flow chart of a paging method according to an embodiment of the present application, which specifically includes the following steps:

[0153] S601, the network device obtains a paging message, the paging message including: an access point association identifier (5G AP Areaidentity);

[0154] The above network equipment may specifically be an access network equipment, for example Figure 6B The Macro gNB shown.

[0155] S602. The network device only sends a paging message to the 5G AP associated with the 5G AP Area identity.

[0156] The above-mentioned network device can also update the 5G AP Area identity, and the update may specifically include: when the 5G AP Identity update occurs, the UE triggers the mobile registration process and updates the 5G AP Identity.

[0157] Optionally, the 5G AP Identity update includes but is not limited to updating the 5G AP Identity broadcast by the cell and the UE's original 5G AP Identity at different times, or updating when the cell does not send the 5G AP Identity. Of course, in actual applications, other methods can also be used to update the 5G AP Identity.

[0158] In the technical solution provided by the present application, a network device obtains paging association information, and the paging association information is used to determine a paging associated access point device; the network device sends a paging message to the paging associated access point device, so that the network device only sends a paging message to the access point associated with the 5G AP Area identity, avoiding forwarding the paging message to a 5G AP that is not associated with the 5G AP Area identity, thereby meeting the requirements for AP deployment and improving network performance.

[0159] Example 7 Figure 7B Taking the network architecture shown in the figure as an example, a paging method provided by the embodiment of the present application is introduced. Figure 7B As shown in FIG. 1 , it is a network architecture diagram of a communication system of Example 7 of this application. Figure 7B As shown, the communication system may include: a macro base station (Macro gNB), access point 1 (5G AP1), access point 2 (5G AP2), access point 3 (5G AP3) and UE, wherein 5G AP1, 5G AP2, and 5G AP3 can all be privately deployed APs, the area coverage corresponding to the Macro gNB can be called a macro cell (Macro cell), the area coverage corresponding to 5G AP1 can be called a closed user group cell 1 (CUG cell1), the area coverage corresponding to 5G AP2 can be called a closed user group cell 2 (CUG cell2), and the area coverage corresponding to 5G AP3 can be called a closed user group cell 3 (CUG cell3). In Example 6, the geographical locations of 5G AP1, 5G AP2, and 5G AP3 are far away, but 5G AP1, 5G AP2, and 5G AP3 have a preset logical relationship. For example, 5G AP1, 5G AP2, and 5G AP3 are deployed by the same person or company. In Example 7, the UE is located in the macro cell and can move to any closed user group cell.

[0160] For example, Fig. 7A FIG. 1 is a flow chart of a paging method according to an embodiment of the present application, which specifically includes the following steps:

[0161] S701. The network device sends a time parameter or a cell reselection parameter to the UE;

[0162] The above network equipment may specifically be an access network equipment, for example Figure 7B The Macro gNB shown.

[0163] S702: When the UE determines that the current state satisfies the time parameter or the cell reselection parameter, the UE reports the cell of the access point device to the network device;

[0164] The condition that the UE determines in step S702 that the current state satisfies the defined time parameter or cell reselection parameter specifically includes:

[0165] If the UE receives the time parameter sent by the network device, the UE determines whether the cell where the stay time is located exceeds the time specified by the time parameter, and if the cell where the stay time is located exceeds the time specified by the time parameter, determines that the condition of the time parameter is satisfied;

[0166] If the UE receives the cell reselection parameters sent by the network device, the UE determines whether the dwell time in the cell exceeds the duration specified by the cell reselection parameters. If the dwell time in the cell exceeds the duration specified by the cell reselection parameters and the signal quality of the cell at the dwell time is greater than the signal quality of the current cell, the UE determines that the conditions for the cell reselection parameters are met.

[0167] S703: The network device obtains a paging message, and sends a paging message to the cell of the reporting access point device.

[0168] The technical solution provided by the present application is that the network device obtains paging association information, and the paging association information is used to determine the paging associated access point device; the network device sends a paging message to the access point device of the cell of the reporting access point device, thereby avoiding forwarding the paging message to the cell of the non-reporting access point device, meeting the requirements of AP deployment and improving network performance.
