Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a paging method and apparatus, a communication device, and a computer-readable storage medium. Background Art

[0002] In order to improve the signal reception strength of the user equipment (UE) and achieve wide-area signal coverage without changing the transmission power, the base station adopts a beam management mechanism. In the beam management mechanism, the base station can have multiple beams, one of which is a control beam and the other beams are service beams. The control beam is used to transmit control messages (such as paging messages) and the service beam is used to transmit service data. The coverage area of ​​the base station has multiple beams, and the control beam is sent in multiple beams in a polling manner (also called scanning).

[0003] The current paging mechanism is either initiated by the Tracking Area Code (TAC) or the Radio Access Network Notification Area (RNA). If the paging is initiated by TAC, it means that each base station under the same TAC needs to send a paging message. At the same time, since the control beam adopts a polling transmission mechanism, it means that each control beam corresponding to each wave position under each base station under the same TAC needs to send a paging message; if the paging is initiated by RNA, it means that each base station under the same RNA needs to send a paging message. At the same time, since the control beam adopts a polling transmission mechanism, it means that each control beam corresponding to each wave position under each base station under the same RNA needs to send a paging message. This paging mechanism has low paging efficiency and will occupy a large amount of control resources. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a paging method and apparatus, a communication device, a chip and a computer-readable storage medium.

[0009] The paging device provided in the present application is applied to a first base station, and the device includes:

[0010] A determination unit, configured to determine a wave position or a wave position group where the first UE is located;

[0016] The computer-readable storage medium provided in the present application is used to store a computer program, and the computer program enables a computer to execute any one of the above methods.

[0017] In the technical solution of the present application, the first base station determines the waveband or waveband group where the first UE is located, and sends a paging message to the first UE based on the waveband or waveband group where the first UE is located, thereby initiating paging oriented to the waveband or waveband group. Compared with initiating paging oriented to TAC or TAC, since the area range of the waveband or waveband group is smaller than the area range of TAC or TAC, the paging oriented to the waveband or waveband group is more accurate, improves the paging efficiency, and saves control resources.

[0037] The following will describe the technical solutions in the embodiments of the present application 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application.

[0039] like Figure 1 As shown, the communication system 100 may include a UE 110 and a network device 120. The network device 120 may communicate with the UE 110 via an air interface. The UE 110 and the network device 120 support multi-service transmission.

[0040] It should be understood that the embodiments of the present application are only exemplified by the 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: 5G communication system (also known as New Radio (NR) communication system), or future communication systems, etc.

[0041] exist Figure 1 In the communication system 100 shown, the network device 120 may be an access network device that communicates with the UE 110. The access network device may provide communication coverage for a specific geographical area, and may communicate with the UE 110 (eg, UE) located in the coverage area.

[0042] The network device 120 may be a base station (gNB) in an NR system, or a network device in a future evolved public land mobile network (PLMN), etc.

[0043] UE 110 may be any UE, including but not limited to UEs that are connected to network device 120 or other UEs by wire or wireless. For example, the UE 110 may refer to an access terminal, 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 (Session Initiation Protocol, SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (Wireless Local Loop, WLL) station, a Personal Digital Assistant (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 UE in a 5G network or a UE in a future evolution network, etc.

[0044] The wireless communication system 100 may also include a core network device 130 for communicating with the base station. The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an access and mobility management function (Access and Mobility Management Function, AMF), and another example, an authentication server function (Authentication Server Function, AUSF), and another example, a user plane function (User Plane Function, UPF), and another example, a session management function (Session Management Function, SMF). In the process of network evolution, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

[0045] Figure 1 A base station, a core network device and two UEs are shown exemplarily. Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include another number of UEs within its coverage area, which is not limited in the embodiments of the present application.

[0046] In non-terrestrial network (NTN) technology, satellite communication is generally used to provide communication services to ground users. Compared with ground cellular network communication, satellite communication has many unique advantages. First, satellite communication is not limited by the user's geographical location. For example, general land communication cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be set up or where communication coverage is not provided due to sparse population. For satellite communication, since one satellite can cover a large area of ​​land, and the satellite can orbit around the earth, in theory, every corner of the earth can be covered by satellite communication. Secondly, satellite communication has great social value. Satellite communication can be covered at a low cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital divide with developed areas and promoting the development of these areas. Thirdly, satellite communication has a long distance, and the cost of communication does not increase significantly as the communication distance increases; finally, satellite communication has high stability and is not restricted by natural disasters.

[0047] NTN technology can be combined with various communication systems. For example, NTN technology can be combined with NR system to form NR-NTN system.

[0048] Figure 2 It is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

[0049] like Figure 2 As shown, the network includes UE 1101 and satellite 1102, and wireless communication can be performed between UE 1101 and satellite 1102. The network formed between UE 1101 and satellite 1102 can also be called NTN. Figure 2 In the architecture of the communication system shown, the satellite 1102 may have the function of a base station, the UE 1101 and the satellite 1102 may communicate directly, and the satellite 1102 may be referred to as an on-board base station. In the system architecture, the satellite 1102 may be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include other numbers of UEs within its coverage area, which is not limited in the embodiments of the present application.

[0050] Figure 3 It is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

[0051] like Figure 3As shown, it includes UE1201, satellite 1202 and base station 1203. Wireless communication can be performed between UE1201 and base station 1203, and base station 1203 can communicate with satellite 1202. The network formed by UE1201, satellite 1202 and base station 1203 can also be called NTN. Figure 3 In the architecture of the communication system shown, the satellite 1202 may have the function of a base station, and the communication between the UE 1201 and the satellite 1202 needs to be relayed by the base station 1203. The base station 1203 may be called a ground transparent forwarding base station, and the satellite 1202 may be called an on-board base station. In this system architecture, the satellite 1202 may be called a network device. In some embodiments of the present application, a plurality of network devices 1203 may be included in the communication system, and each network device 1203 may include other numbers of UEs within its coverage area, which is not limited in the embodiments of the present application.

[0052] It should be understood that the satellite 1102 or satellite 1202 includes but is not limited to:

[0053] Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. Satellites can use multiple beams to cover the ground. For example, a satellite can form dozens or even hundreds of beams to cover the ground. In other words, a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers to ensure satellite coverage and improve the system capacity of the entire satellite communication system.

[0054] It should be noted that Figures 1 to 3It 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 a device (for example, including UE and network equipment), and the present application does not limit its specific implementation method. For example, predefined may refer to a definition in a 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 the NR protocol and related protocols used in future communication systems, which is not limited in the present application.

[0055] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant 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.

[0056] In order to improve the signal reception strength of ground UEs while maintaining the same transmission power and achieving wide area coverage, the satellite can adopt the NR beam management mechanism. In the NR beam management mechanism, the base station can have multiple beams, one of which is a control beam and the remaining beams are service beams. The control beam is used for the transmission of downlink control messages and / or uplink control messages. Downlink control messages include synchronization signal blocks (Synchronization Signal / PBCH Block, SSB), broadcast messages, paging messages, etc., and uplink control messages include random access request messages, etc. The service beam is used for the transmission of service data. The coverage area of ​​the base station has multiple wave positions, and the control beam is sent in multiple wave positions in a polling manner (also called scanning).

[0057] Figure 4 The diagram shows a schematic diagram of satellite wide-area coverage. The satellite has multiple beams, one of which is a control beam and the other beams are service beams. The control beam adopts a polling transmission mechanism, and the service beam is sent on demand after the UE accesses. The coverage area of ​​the satellite (the area within the ellipse dotted line) contains 8 beam positions (there will be more beam positions in the actual system, this is just an example), and the satellite's control beam starts polling from beam position 1 to ensure that all 8 beam positions can be polled.

[0058] In the NR paging mechanism, the paging initiated by the UE in the IDLE state is initiated to the TAC, and the paging initiated by the UE in the INACTIVE state is initiated to the RNA cell, which can contain one or more cells. If the paging is initiated to the TAC, it means that each satellite under the same TAC needs to send a paging message. At the same time, since the control beam adopts a polling transmission mechanism, it means that the control beam corresponding to each wave position under each satellite under the same TAC needs to send a paging message, such as Figure 5 If the paging is initiated towards RNA, it means that each satellite under the same RNA needs to send a paging message. At the same time, since the control beam adopts a polling transmission mechanism, it means that the control beam corresponding to each wave position of each satellite under the same RNA needs to send a paging message, as shown in Figure 6 shown.

[0059] The more beams a satellite covers, the more control resources will be occupied for the control beam. Taking the satellite coverage area containing 8 beams as an example, the paging message needs to be sent on all 8 beams of the satellite. When the paging cycle remains unchanged, the paging resource occupancy is 8 times that of the same cell on the ground. Therefore, how to achieve accurate paging as much as possible and reduce the control resource occupancy becomes a problem that needs to be considered in satellite communications. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0060] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily 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. The embodiments of the present application include at least part of the following contents.

[0061] It should be noted that the "base station" described in the embodiments of the present application can be a satellite base station or a ground transparent forwarding base station. The meanings of the satellite base station and the ground transparent forwarding base station can refer to the above-mentioned related description.

[0062] The technical solution of the embodiment of the present application proposes a paging mechanism for wave positions or wave position groups in order to achieve precise paging. In the paging mechanism for wave positions or wave position groups, the relevant concepts of wave positions or wave position groups need to be enhanced. 1) Enhancement of wave positions: Each wave position in the coverage area of ​​the base station has a corresponding identifier. As an implementation method, the base station can send the SSB corresponding to the wave position in the wave position, and the index of the SSB can be used as the identifier of the wave position. 2) Enhancement of wave position groups: One or more wave positions in the coverage area of ​​the base station are combined into a wave position group. There can be one or more wave position groups in the coverage area of ​​the base station, and each wave position group has a corresponding identifier. As an implementation method, the base station can send the identifier of the wave position group to which the wave position belongs in the wave position. 3) Enhancement of entities: A new entity is introduced on the base station side, which can be called a user location management entity (the name of this entity is not limited in this application), and the entity is used for the base station to perform paging oriented to wave positions or wave position groups.

[0063] Figure 7 This is a schematic diagram of the paging method provided in the embodiment of the present application. Figure 1 ,like Figure 7 As shown, the paging method includes the following steps:

[0064] Step 701: The first base station determines the beam position or beam position group where the first UE is located, and sends a paging message to the first UE based on the beam position or beam position group where the first UE is located.

[0065] In some embodiments, the first UE is an idle UE. In this case, the paging instruction is sent by the first core network to all base stations within the TAC, where the first base station is a base station within the TAC. After receiving the paging instruction sent by the first core network, the first base station determines the wave position or wave position group where the first UE is located, and sends a paging message to the first UE based on the wave position or wave position group where the first UE is located.

[0066] In some other embodiments, the first UE is an inactive UE. In this case, the paging instruction is sent by the first core network to all base stations within the RNA, where the first base station is a base station within the RNA. After receiving the paging instruction sent by the first core network, the first base station determines the wave position or wave position group where the first UE is located, and sends a paging message to the first UE based on the wave position or wave position group where the first UE is located.

[0067] In some implementations, the paging instruction received by the first base station from the first core network carries the first UEID, and the first UE ID is used to identify the first UE, that is, the first UE ID is the identifier of the first UE. After receiving the paging instruction from the first core network, the first base station queries whether the first UE ID exists in the first information, and sends the second information to the first core network; wherein, if the first UE ID exists in the first information, the second information indicates that the first UE corresponding to the first UE ID is within the service range of the first base station; if the first UE ID does not exist in the first information, the second information indicates that the first UE corresponding to the first UE ID is not within the service range of the first base station.

[0068] Here, the user location management entity of the first base station maintains the first information, which stores the UE ID of the UE within the service range of the first base station and the waveband or waveband group information corresponding to the UE ID. The first base station queries whether the first UE ID exists in the first information through the user location management entity.

[0069] In some implementations, if the first UE ID exists in the first information, the first base station obtains the beam position or beam position group information corresponding to the first UE ID according to the first information; wherein the beam position or beam position group information corresponding to the first UE ID is used to determine the beam position or beam position group where the first UE is located. Here, the beam position or beam position group information may be a beam or beam position group identifier, and the specific implementation of the beam or beam position group identifier may refer to the above description.

[0070] In an embodiment of the present application, the above-mentioned first information stores the UE ID of the UE within the service range of the first base station and the wave position or wave position group information corresponding to the UE ID. The initial association between the UE ID and the wave position or wave position group information can be achieved through an intra-cell registration process. The change association between the UE ID and the wave position or wave position group information can be achieved through an intra-cell (i.e., within the same cell) wave position or wave position group change process, or through an inter-cell (i.e., different cell) wave position or wave position group change process within the same TAC, or through an inter-cell (i.e., different cell) wave position or wave position group change process within different TACs (i.e., different cell) or through a location update process. It is described below.

[0071] Solution 1: Initial association between UE ID and wave position or wave position group information

[0072] In some embodiments, the first base station polls and sends wave position or wave position group information at each wave position of the first base station, wherein the wave position or wave position group information sent at each wave position is an identifier of the wave position or an identifier of the wave position group to which the wave position belongs; the first base station receives an initial registration message sent by the first UE, and the initial registration message includes the first UE ID and the wave position or wave position group information corresponding to the first UEID, wherein the wave position or wave position group information corresponding to the first UE ID is the wave position or wave position group information received by the first UE through the wave position where the first UE is located; the first base station stores the first UE ID and the wave position or wave position group information corresponding to the first UE ID in the above-mentioned first information, thereby realizing the initial association between the UE ID and the wave position or wave position group information.

[0073] Solution 2: Change association between UE ID and wave position or wave position group information

[0074] Scheme 2-1) In some embodiments, the first base station polls and sends wave position or wave position group information at each wave position of the first base station, wherein the wave position or wave position group information sent at each wave position is the identifier of the wave position or the identifier of the wave position group to which the wave position belongs; the first base station receives a location change message sent by the first UE, and the location change message includes the first UE ID and the wave position or wave position group information corresponding to the first UE ID, wherein the wave position or wave position group information corresponding to the first UE ID is the wave position or wave position group information received by the first UE through the wave position where the first UE is located; the first base station updates the first UE ID and the wave position or wave position group information corresponding to the first UEID to the first information, thereby realizing the change association between the UE ID and the wave position or wave position group information.

[0075] In one scenario, the sending of the location change message is triggered based on the following event: the cell where the first UE is located remains unchanged and the wave position or wave position group where the first UE is located changes. The change association between the UE ID and the wave position or wave position group information in this scenario specifically refers to: the change association between the UE ID in the cell and the wave position or wave position group information.

[0076] In another scenario, the sending of the above-mentioned location change message is triggered based on the following event: the cell where the first UE is located changes. The change association between the UE ID and the wave position or wave position group information in this scenario specifically refers to: the change association between the UE ID and the wave position or wave position group information between cells. In some embodiments, the TAC where the first UE is located has not changed and the cell where the first UE is located has changed, and the change association between the UE ID and the wave position or wave position group information between cells specifically refers to: the change association between the UE ID and the wave position or wave position group information between cells within the same TAC range. In some embodiments, the above-mentioned location change message also includes an identifier of the first cell and an identifier of the second cell, the first cell is a new cell after the cell changes, and the second cell is the original cell before the cell changes; the first base station sends a de-association message to the second base station, and the de-association message is used to indicate the deletion of the wave position or wave position group information corresponding to the first UE ID, wherein the first base station is the base station where the first cell is located, and the second base station is the base station where the second cell is located.

[0077] In another scenario, the sending of the above-mentioned location change message is triggered based on the following event: the TAC where the first UE is located changes. The change association between the UE ID and the wave position or wave position group information in this scenario specifically refers to: the change association between the UEID between TACs and the wave position or wave position group information. In some embodiments, the above-mentioned location change message also includes the first TAC, the second TAC, the identifier of the first cell, and the identifier of the second cell, the first TAC is the new TAC after the TAC changes, the second TAC is the original TAC before the TAC changes, the first cell is the new cell after the TAC changes, and the second cell is the original cell before the TAC changes; the first base station sends a de-association message to the second base station through forwarding by the first core network and the second core network, and the de-association message is used to indicate the deletion of the wave position or wave position group information corresponding to the first UE ID, wherein the first base station is the base station where the first cell is located, the second base station is the base station where the second cell is located, the first core network is the core network corresponding to the first base station, and the second core network is the core network corresponding to the second base station.

[0078] Scheme 2-2) In some embodiments, the first base station receives a location update message periodically sent by the first UE, and the location update message includes the first UE ID and the wave position or wave position group information corresponding to the first UE ID; the first base station updates the first UE ID and the wave position or wave position group information corresponding to the first UE ID into the first information.

[0079] Here, the location update message periodically sent by the first UE can be implemented through a timer. The duration of the timer is the period. The first UE starts the timer. After the timer expires, the first UE sends the location update message and resets the timer. After the timer expires, the first UE sends the location update message again and resets the timer, thereby realizing the first UE periodically sending the location update message.

[0080] Figure 8 This is a schematic diagram of the paging method provided in the embodiment of the present application. Figure 2 ,like Figure 8 As shown, the paging method includes the following steps:

[0081] Step 801: A first UE receives beam position or beam position group information sent by a first base station, where the beam position or beam position group information is used to determine the beam position or beam position group where the first UE is located, and the beam position or beam position group where the first UE is located is used by the first base station to initiate paging to the first UE.

[0082] In an embodiment of the present application, a user location management entity of a first base station maintains first information, and the first information stores the UE ID of a UE within the service range of the first base station and the wave position or wave position group information corresponding to the UE ID. The initial association between the UE ID and the wave position or wave position group information can be achieved through a cell registration process. The change association between the UE ID and the wave position or wave position group information can be achieved through a wave position or wave position group change process within a cell (i.e., within the same cell), or through a wave position or wave position group change process between cells (i.e., between different cells) within the same TAC, or through a wave position or wave position group change process between cells (i.e., between different cells) within different TACs, or through a location update process.

[0083] Solution 1: Initial association between UE ID and wave position or wave position group information

[0084] In some embodiments, the first UE sends an initial registration message to the first base station, and the initial registration message includes the first UE ID and the wave position or wave position group information corresponding to the first UE ID, wherein the first UE ID is an identifier of the first UE, and the wave position or wave position group information corresponding to the first UE ID is the wave position or wave position group information received by the first UE.

[0085] Solution 2: Change association between UE ID and wave position or wave position group information

[0086] Scheme 2-1) In some embodiments, the first UE sends a location change message to the first base station, and the location change message includes the first UE ID and the wave position or wave position group information corresponding to the first UE ID, wherein the first UE ID is the identifier of the first UE, and the wave position or wave position group information corresponding to the first UE ID is the wave position or wave position group information received by the first UE.

[0087] In one scenario, the sending of the location change message is triggered based on the following event: the cell where the first UE is located remains unchanged and the wave position or wave position group where the first UE is located changes. The change association between the UE ID and the wave position or wave position group information in this scenario specifically refers to: the change association between the UE ID in the cell and the wave position or wave position group information.

[0088] In another scenario, the sending of the above-mentioned location change message is triggered based on the following event: the cell where the first UE is located changes. The change association between the UE ID and the wave position or wave position group information in this scenario specifically refers to: the change association between the UE ID and the wave position or wave position group information between cells. In some embodiments, the TAC where the first UE is located has not changed and the cell where the first UE is located has changed, and the change association between the UE ID and the wave position or wave position group information between cells specifically refers to: the change association between the UE ID and the wave position or wave position group information between cells within the same TAC range. In some embodiments, the above-mentioned location change message also includes an identifier of the first cell and an identifier of the second cell, the first cell is a new cell after the cell changes, and the second cell is the original cell before the cell changes.

[0089] In another scenario, the sending of the above-mentioned location change message is triggered based on the following event: the TAC where the first UE is located changes. The change association between the UE ID and the wave position or wave position group information in this scenario specifically refers to: the change association between the UEID and the wave position or wave position group information between TACs. In some embodiments, the above-mentioned location change message also includes the first TAC, the second TAC, the identifier of the first cell, and the identifier of the second cell, the first TAC is the new TAC after the TAC changes, the second TAC is the original TAC before the TAC changes, the first cell is the new cell after the TAC changes, and the second cell is the original cell before the TAC changes.

[0090] Scheme 2-2) In some embodiments, the first UE periodically sends a location update message to the first base station, and the location update message includes the first UE ID and the wave position or wave position group information corresponding to the first UE ID, wherein the first UE ID is the identifier of the first UE, and the wave position or wave position group information corresponding to the first UE ID is the wave position or wave position group information received by the first UE.

[0091] Here, the location update message periodically sent by the first UE can be implemented through a timer. The duration of the timer is the period. The first UE starts the timer. After the timer expires, the first UE sends the location update message and resets the timer. After the timer expires, the first UE sends the location update message again and resets the timer, thereby realizing the first UE periodically sending the location update message.

[0092] The technical solution of the embodiment of the present application is illustrated below with reference to specific application examples.

[0093] Application Example 1

[0094] In this application example, precise paging is performed on idle UEs oriented to the beam position or beam position group. Fig. 9 As shown, the following steps are included:

[0095] Step 901: The core network sends a paging instruction to the base station within the TAC range.

[0096] Here, for the UE in the idle state, the paging range of the paging instruction is all base stations within the TAC range, that is, the core network sends the paging instruction to all base stations within the TAC range.

[0097] Step 902: The user location management entity of the base station queries whether the UE ID carried in the paging instruction exists in the first information.

[0098] Step 903: The base station sends second information to the core network, where the second information is used to indicate whether the UE corresponding to the UE ID is within the service range of the base station.

[0099] Here, if the UE ID is found in the first information, the second information indicates that the UE corresponding to the UE ID is within the service range of the base station; if the UE ID is not found in the first information, the second information indicates that the UE corresponding to the UE ID is not within the service range of the base station.

[0100] Further, if it is found that the UE ID exists in the first information, the wave position or wave position group information corresponding to the UE ID is obtained from the first information.

[0101] Step 904: The base station sends a paging message to the UE according to the beam position or beam position group information corresponding to the above UE ID.

[0102] Application Example 2

[0103] In this application example, accurate paging oriented to a wave position or a wave position group is performed for an inactive UE.

[0104] like Fig.10 As shown, the following steps are included:

[0105] Step 1001: The core network sends a paging instruction to a base station within the RNA range.

[0106] Here, for the inactive UE, the paging range of the paging instruction is all base stations within the RNA range, that is, the core network sends the paging instruction to all base stations within the RNA range.

[0107] Step 1002: The user location management entity of the base station queries whether the UE ID carried in the paging instruction exists in the first information.

[0108] Step 1003: The base station sends second information to the core network, where the second information is used to indicate whether the UE corresponding to the UE ID is within the service range of the base station.

[0109] Here, if the UE ID is found in the first information, the second information indicates that the UE corresponding to the UE ID is within the service range of the base station; if the UE ID is not found in the first information, the second information indicates that the UE corresponding to the UE ID is not within the service range of the base station.

[0110] Further, if it is found that the UE ID exists in the first information, the wave position or wave position group information corresponding to the UE ID is obtained from the first information.

[0111] Step 1004: The base station sends a paging message to the UE according to the beam position or beam position group information corresponding to the above UE ID.

[0112] Application Example 3

[0113] In this application example, the initial association between the UE ID and the beam position or beam position group information is achieved through the intra-cell registration process. Fig.11 As shown, the following steps are included:

[0114] Step 1101: The base station polls and sends the beam position or beam position group information and cell information in each beam position.

[0115] For example, the coverage area of ​​the base station includes 8 beams, and the base station polls and sends the beam information of each beam and / or the bit group information of the beam group to which the beam belongs and the cell information in each of the 8 beams.

[0116] Step 1102: The UE receives the beam position or beam position group information and cell information corresponding to a certain beam position in the beam position.

[0117] Step 1103: The UE initiates a traditional registration process.

[0118] Step 1104: The UE initiates an intra-cell registration process.

[0119] Here, if the UE is not registered with the network, the UE initiates a traditional registration process and an intra-cell registration process after receiving the wave position or wave position group information and the cell information. The intra-cell registration process can be performed after the traditional registration process or within the traditional registration process.

[0120] Here, in the intra-cell registration process, the UE sends an initial registration message to the base station, and the initial registration message includes the UE ID of the UE and the beam position or beam position group information corresponding to the UE ID.

[0121] Step 1105: The user location management entity of the base station initially associates the UE ID and the beam position or beam position group information corresponding to the UE ID with respect to the UE.

[0122] Here, the base station initially associates the UE ID and the wave position or wave position group information corresponding to the UE ID, which specifically means: the base station stores the UE ID and the wave position or wave position group information corresponding to the UE ID in the first information. The specific implementation of the first information can refer to the above-mentioned related description.

[0123] Application Example 4

[0124] In this application example, the change association between the UE ID and the wave position or wave position group information is realized through the intra-cell (i.e., within the same cell) wave position or wave position group change process, which is applicable to the scenario where the UE switches from the original wave position to the new wave position in the same cell. Fig.12 As shown, the following steps are included:

[0125] Step 1201: The base station polls and sends the beam position or beam position group information and cell information in each beam position.

[0126] For example, the coverage area of ​​the base station includes 8 beams, and the base station polls and sends the beam information of each beam and / or the bit group information of the beam group to which the beam belongs and the cell information in each of the 8 beams.

[0127] Step 1202: The UE receives the beam position or beam position group information and cell information corresponding to a certain beam position in the beam position, and compares the information with the stored information. If the cell information remains unchanged and the beam position or beam position group information changes, step 1203 is executed.

[0128] Step 1203: The UE initiates a process of changing the wavelength / wavelength group within the cell.

[0129] Here, in the intra-cell beam position / beam position group change process, the UE sends a location change message to the base station, and the location change message includes the UE ID of the UE and new beam position or beam position group information corresponding to the UE ID.

[0130] Step 1204: The user location management entity of the base station changes the association between the UE ID and the new beam position or beam position group information corresponding to the UE ID.

[0131] Here, the base station changes the association between the UE ID and the new wave position or wave position group information corresponding to the UE ID, which specifically means: the base station updates the UE ID and the new wave position or wave position group information corresponding to the UE ID to the first information. The specific implementation of the first information can refer to the above-mentioned related description.

[0132] Application Example 5

[0133] In this application example, the change association between the UE ID and the wave position or wave position group information is realized through the inter-cell (i.e., different cells) wave position or wave position group change process within the same TAC, which is applicable to the scenario where the UE switches from the original base station (i.e., the second base station) to the new base station (i.e., the first base station) within the same TAC. Fig.13 As shown, the following steps are included:

[0134] Step 1301: The new base station polls and sends the beam position or beam position group information and cell information in each beam position.

[0135] For example, the coverage area of ​​the new base station includes 8 beams, and the new base station polls and sends the beam information of each beam and / or the bit group information of the beam group to which the beam belongs and the cell information in each of the 8 beams.

[0136] Step 1302: The UE receives the beam position or beam position group information and cell information corresponding to a beam position of the new base station, and compares the information with the stored information. If the TAC remains unchanged and the cell information changes, step 1303 is executed.

[0137] Step 1303: The UE initiates an inter-cell waveband / waveband group change procedure.

[0138] Here, if the UE is in an idle state, the UE can directly initiate the inter-cell wave position / wave position group change process. If the UE is in an inactive state, the UE can initiate the inter-cell wave position / wave position group change process within the RNA update process, or after the RNA update process.

[0139] Here, in the inter-cell waveband / waveband group change process, the UE sends a location change message to the new base station, which includes the identifier of the new cell, the identifier of the original cell, the UE ID of the UE, and the new waveband or waveband group information corresponding to the UE ID.

[0140] Step 1304: The user location management entity of the new base station changes the association between the UE ID and the new beam position or beam position group information corresponding to the UE ID.

[0141] Here, the new base station changes the association between the UE ID and the new wave position or wave position group information corresponding to the UE ID, which specifically means: the base station updates the UE ID and the new wave position or wave position group information corresponding to the UE ID to the first information. The specific implementation of the first information can refer to the above-mentioned related description.

[0142] Step 1305: The new base station initiates a de-association process for the beam position or beam position group information of the UE to the original base station.

[0143] In the de-association process of the beam bit or beam bit group information, the new base station sends a de-association message to the original base station, where the de-association message is used to instruct to delete the beam bit or beam bit group information corresponding to the UE ID of the UE.

[0144] Step 1306: The user location management entity of the original base station deletes the beam position or beam position group information corresponding to the UE ID of the UE, thereby achieving de-association of the beam position or beam position group information for the UE.

[0145] Application Example 6

[0146] In this application example, the change association between the UE ID and the wave position or wave position group information is realized through the process of changing the wave position or wave position group between cells (i.e., between different cells) in different TACs. It is applicable to the scenario where the UE switches from the original base station (i.e., the second base station) to the new base station (i.e., the first base station) between different TACs, where the original base station and the new base station are located in different TACs. Fig.14 As shown, the following steps are included:

[0147] Step 1401: The new base station polls and sends the beam position or beam position group information and cell information in each beam position.

[0148] For example, the coverage area of ​​the new base station includes 8 beams, and the new base station polls and sends the beam information of each beam and / or the bit group information of the beam group to which the beam belongs and the cell information in each of the 8 beams.

[0149] Step 1402: The UE receives the beam position or beam position group information and cell information corresponding to a beam position of the new base station, and compares the information with the stored information. If the TAC changes, execute step 1403.

[0150] Step 1403: The UE initiates an inter-cell waveband / waveband group change procedure.

[0151] Here, the inter-cell wave position / wave position group change process refers to the inter-cell wave position / wave position group change process within different TACs.

[0152] Here, the UE may initiate an inter-cell beam position / beam position group change procedure within a traditional Tracking Area Update (TAU) procedure, or may initiate an inter-cell beam position / beam position group change procedure after a traditional TAU update procedure.

[0153] Here, in the inter-cell wave position / wave position group change process, the UE sends a location change message to the new base station, which includes the identifier of the new TAC, the identifier of the original TAC, the identifier of the new cell, the identifier of the original cell, the UE ID of the UE, and the new wave position or wave position group information corresponding to the UE ID.

[0154] Step 1404: The user location management entity of the new base station changes the association between the UE ID and the new beam position or beam position group information corresponding to the UE ID.

[0155] Here, the new base station changes the association between the UE ID and the new wave position or wave position group information corresponding to the UE ID, which specifically means: the base station updates the UE ID and the new wave position or wave position group information corresponding to the UE ID to the first information. The specific implementation of the first information can refer to the above-mentioned related description.

[0156] Step 1405: The new base station initiates a de-association process for the waveband or waveband group information of the UE to the new core network.

[0157] In the de-association process of the waveband or waveband group information, the new base station sends a de-association message to the new core network, where the de-association message is used to instruct to delete the waveband or waveband group information corresponding to the UE ID of the UE.

[0158] Step 1406: The new core network forwards the de-association message to the original core network.

[0159] Step 1407: The original core network forwards the above de-association message to the original base station.

[0160] Step 1408: The user location management entity of the original base station deletes the beam position or beam position group information corresponding to the UE ID of the UE, thereby de-associating the beam position or beam position group information for the UE.

[0161] Application Example 7

[0162] In this application example, the change association between the UE ID and the wave position or wave position group information is realized through the location update process, which is suitable for the scenario where the UE performs TAU. Fig.15 As shown, the following steps are included:

[0163] Step 1501: The UE initiates a scheduled TAU procedure to the base station.

[0164] Step 1502: The UE initiates a timing update procedure of a beam position / beam position group within the cell.

[0165] Here, the UE may initiate a timing update procedure for a waveband or a waveband group within a cell before, during, or after the timing TAU procedure.

[0166] Here, in the periodic update process of the beam position / beam position group within the cell, the UE sends a location update message to the base station, and the location change message includes the UE ID of the UE and the new beam position or beam position group information corresponding to the UE ID.

[0167] Step 1503: The user location management entity of the base station changes the association between the UE ID and the new beam position or beam position group information corresponding to the UE ID.

[0168] Here, the base station changes the association between the UE ID and the new wave position or wave position group information corresponding to the UE ID, which specifically means: the base station updates the UE ID and the new wave position or wave position group information corresponding to the UE ID to the first information. The specific implementation of the first information can refer to the above-mentioned related description.
