Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to Chinese Patent Application No. 202110821428.2 filed in China on July 20, 2021, and Chinese Patent Application No. 202210003218.7 filed in China on January 4, 2022, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of communications technology, and more particularly to paging methods, devices, apparatus, and computer storage media. [Background technology]

[0003] Future mobile communication networks will have terminals with various types of capabilities, such as reduced capability (RedCap) terminals and non-RedCap terminals. Generally, RedCap terminals are low-complexity, low-cost terminals with lower capabilities than non-RedCap terminals. RedCap terminals can be further subdivided into at least two types: RedCap terminals with one receive antenna (1rx) and RedCap terminals with two receive antennas (2rx).

[0004] In a mobile communication network, only some cells can serve RedCap terminals, and these cells indicate by broadcast message whether to allow 1rx RedCap terminals, 2rx RedCap terminals, or both 1rx RedCap terminals and 2rx RedCap terminals to be in service. If a cell (e.g., Cell A) does not support the in-service of 1rx RedCap terminals, the 1rx RedCap terminal (e.g., Terminal A) does not monitor paging in this cell.

[0005] However, in the related art, the paging message for terminal A is still transmitted from cell A (assuming that in the same tracking area (TA), some cells support 1rx RedCap terminals and some do not), which results in unnecessary waste of radio resources. At the same time, other terminals in this cell are falsely woken up by the paging physical downlink control channel (PDCCH) and receive the paging PDCCH, resulting in unnecessary power consumption.

[0026] The following clearly describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application fall within the scope of protection of the present application.

[0027] The terms "first," "second," etc. in the specification and claims of this application distinguish between similar objects and do not describe a specified order or sequence. It is to be understood that terms used in this manner are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein, and that objects distinguished by "first" and "second" are generally of the same type and do not limit the number of objects; for example, a first object may be one or more. Furthermore, the term "and" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.

[0028] It should be noted that the techniques described in the embodiments of the present application are not limited to New Radio (NR) systems or Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-Carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the described techniques may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. In the following description, for illustrative purposes, an NR system will be described, and NR terminology will be used in most of the following description, however, these technologies may also be used in applications other than NR system applications, such as sixth generation (6G) applications.th This may be applied to 6G (6th Generation) communication systems.

[0029] To facilitate understanding of the embodiments of the present application, the following technical points will be introduced first.

[0030] I. Cell Bar Mechanism A cell can indicate by a specific information field in a system message that it prohibits the presence of certain types of terminals. For example, a cell can: (1) Prohibiting the presence of 1rx RedCap terminals (e.g., User Equipment (UE)) and (2) Prohibiting the presence of 2rx RedCap UE, (3) Prohibiting non-RedCap UE from being present; (4) prohibiting all UEs from entering the area.

[0031] 2. Paging mechanism The network finds the paged UE by paging. When the UE is in Radio Resource Control (RRC) idle or inactive, the UE reports its current location area (a location area includes one or more cells) to the network (New Work (NW)). After the UE moves out of its current location area, the UE initiates a location registration or update process with the NW and receives a new location area configured by the NW. Therefore, the NW only knows the current location area of ​​the RRC idle or inactive UE.

[0032] When there is a need to page an RRC idle or inactive UE, the core network or anchor base station transmits the page in one or more cells in the UE's current location area.

[0033] Air interface paging can be triggered by the core network (see FIG. 1) or the access network (see FIG. 2).

[0034] In one location area, there are multiple cells, some of which may support the presence of 1rx RedCap UEs and some of which may not. Therefore, when the network needs to page a 1rx RedCap UE (e.g., UE A), a paging message on the N2 interface or a paging message on the Xn interface may be sent to a cell (e.g., CELL A) that does not support the presence of 1rx RedCap UEs, which may result in Cell A sending a paging message to UE A. Since UE A does not receive the paging message in Cell A, it is unnecessary for Cell A to send a paging message to UE A.

[0035] Referring to FIG. 3, a block diagram of a wireless communication system to which the embodiment of the present application can be applied is shown. The wireless communication system includes a terminal 31, a terminal 32, and a network side device 33. Here, the terminal may be referred to as a terminal equipment or UE, and the terminal may be a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (Mobile Internet Device (MID)), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and the wearable device includes a smart watch, a bracelet, an earphone, glasses, etc. It should be noted that the embodiment of the present application does not limit the specific types of the terminal 31 and the terminal 32.

[0036] The network side equipment 33 may be a base station or a core network, where the base station may be a Node B, an evolved Node B (eNB), an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a BNode, a The base station may also be referred to as a base station, an evolved B node (gNB), a home B node, a home evolved B node, a wireless local area network (WLAN) access point, a wireless fidelity (WiFi) node, a transmitting receiving point (TRP), a radio access network node, or any other appropriate term in the art, and as long as the same technical effect is achieved, the base station is not limited to the specified technical term. It should be noted that in the embodiments of this application, only base stations in an NR system are taken as examples, and the specific type of base station is not limited.

[0039] As can be understood, whether the terminal's receiving antenna is 1rx or 2rx belongs to the terminal's radio access capabilities, and the core network encryption algorithm supported by the terminal, etc. belong to the core network capabilities. Generally, the core network does not decipher the terminal's radio access capabilities, and in the embodiments of the present application, the core network needs to know the type and / or radio access capabilities of the terminal to send a paging message.

[0055] Referring to FIG. 6, an embodiment of the present application provides a paging method, and specific steps include step 601.

[0056] Step 601: A second radio access network device (e.g., an anchor base station) receives from a terminal one or more of first information indicating the radio access capabilities of the terminal and second information indicating the terminal type of the terminal, or the second radio access network device receives from a first radio access network device third information indicating the terminal type of the terminal that is prohibited from or allowed to be within the range of the first radio access network device.

[0057] In one embodiment of the present application, the method further comprises:

[0090] In one alternative embodiment, the method comprises: The network side device receives second information from a first radio access network device; or The network side device further includes acquiring second information through an operation, administration, and maintenance (OAM) configuration; Here, the second information is A terminal type of a terminal that is prohibited from accessing or permitted to access by the first radio access network device; A terminal type supported by the first radio access network device; the first radio access network device is a network device supporting a first terminal type; In one alternative embodiment, the terminal types of the terminals that are barred or permitted to be in the range of the first radio access network device are: A terminal type of a terminal that is prohibited from visiting or allowed to visit all cells of the first radio access network device; Or, The terminal types of terminals that are barred from or allowed to be in the range of each cell of the first radio access network device are included.

[0091] As an alternative embodiment, the method further includes the network side device obtaining, from the terminal, one or more of third information indicating the radio access capability of the terminal and fourth information indicating the terminal type of the terminal, or the network side device receiving, from a third access network device, one or more of the third information indicating the radio access capability of the terminal and fourth information indicating the terminal type of the terminal.

[0092] In one alternative embodiment, the radio access capability, the terminal type or the first terminal type is a RedCap terminal having one receiving antenna; a RedCap terminal having two receiving antennas; and one or more of other terminals other than RedCap terminals having one or two receiving antennas, which terminals the radio access network equipment can prohibit from accessing by broadcast messages.

[0094] In one alternative embodiment, when the network side device is a core network device, the method further comprises: The method further includes the core network device determining a terminal type of the paged terminal based on the third information and / or the fourth information.

[0095] In an embodiment of the present application, waste of radio resources (carrying paging messages) due to sending a page to a paged terminal in a cell that does not allow the paged terminal to be present is avoided, and unnecessary energy consumption due to terminals in the cell that are not paged terminals being woken up by the paging message is avoided.

[0096] Example 1: Core Network Paging (CN Paging) In the first embodiment, the interface message can indicate the terminal type of the terminal that the base station prohibits from accessing.

[0097] Referring to FIG. 10, the specific steps are as follows:

[0098] Step 1: UE A reports its terminal type to the core network, and the terminal type is a) 1rx RedCap terminal; b) 2rx RedCap terminals; c) Any other terminal other than the above a) and b) that is a certain terminal type that the cell can prohibit from accessing by a broadcast message.

[0099] Step 2: Base station A reports to the core network the terminal types of terminals that are barred from or allowed to be within the coverage area of ​​its subordinate cell, and the method may be one of the following:

[0100] a) The terminal type reported by the base station applies to all cells under its control, that is, all cells under its control either prohibit or allow the presence of terminals of the reported type.

[0101] b) The base station reports the terminal type of terminals that are prohibited from entering the range for each cell. In other words, each subordinate cell can prohibit the entry of different types of terminals, and the base station reports the terminal types of terminals that are prohibited from entering or allowed to enter the range for each cell.

[0102] As can be seen, in step 2, the terminal types of the terminals barred or allowed to visit the cell correspond one-to-one to the terminal types in step 1, or there is a fixed and / or core network known mapping relationship between the two; Step 3: When the core network pages UE A, the core network sends a paging message (e.g., an N2 paging message) only to base stations within UE A's registration area that have cells that allow terminals of the type to which UE A belongs.

[0103] Step 4: Base station A transmits an air interface paging message via the cells under its control that allow UE A's terminal type to be located therein.

[0104] As can be understood, the core network can instruct base station A to the cells to which paging needs to be sent or to the cells to which paging does not need to be sent. For example, if only some cells under base station A support the presence of terminals of the type to which UE A belongs, the core network can instruct base station A to the cells to which paging needs to be sent or to the cells to which paging does not need to be sent.

[0105] Example 1a: Radio Access Network Paging (RAN Paging) Base station B is one of the neighboring base stations of base station A, and base station A is the anchor base station of UE A.

[0106] In the related art, the anchor base station knows the type of the inactive UE.

[0107] Referring to FIG. 11, the specific steps are as follows:

[0108] Step 0: UE A reports the terminal type to base station A, and the terminal type is a) 1rx RedCap terminal; b) 2rx RedCap terminals; c) Other than a) and b) above, the cell includes one of the following: and other terminals of a certain terminal type that the cell can prohibit from accessing by a broadcast message.

[0109] Step 1: Base station B notifies base station A of the terminal types of terminals that are prohibited from entering the cell under its control, and the method may be one of the following.

[0110] a) The instruction from base station B to base station A applies to all subordinate cells, i.e., all subordinate cells prohibit the access of the reported type of terminal; b) Base station B instructs base station A on the terminal types of terminals to be prohibited from accessing the area for each cell, That is, each subordinate cell can prohibit different types of terminals from accessing its area, and base station B indicates the terminal types of terminals that each cell prohibits from accessing its area.

[0111] Step 2: When the anchor base station (base station A) pages UE A, it sends a paging message (e.g., an Xn paging message) only to base stations (e.g., base station B) within the registration area of ​​UE A that have cells that allow the presence of terminals of the type to which UE A belongs.

[0112] Step 3: Base station B sends an air interface paging message through the cells under its control that allow UE A's terminal type to be located therein.

[0113] As can be understood, base station A can instruct base station B to the cells to which paging needs to be sent, or to the cells to which paging does not need to be sent. For example, if only some cells under base station A support the presence of terminals of the type to which UE A belongs, base station A can instruct base station B to the cells to which paging needs to be sent, or to the cells to which paging does not need to be sent.

[0114] Example 2: CN Paging (Indicating the type of paged terminal in the NG paging message) Referring to FIG. 12, the specific steps are as follows:

[0115] Step 1: UE A reports its terminal type to the core network, and the terminal type is a) 1rx RedCap terminal; b) 2rx RedCap terminals; c) Other than a) and b) above, the cell includes one of the following: and other terminals of a certain terminal type that the cell can prohibit from accessing by a broadcast message.

[0116] Step 2: When paging UE A, the core network sends a paging message (e.g., an N2 paging message) to a base station within the UE location area, and indicates the type of the paged terminal in the paging message; Step 3: After receiving the paging message, the base station transmits a paging message (for example, an air interface paging message) in a cell that allows the paged terminal to be located.

[0117] Example 2a: RAN Paging (indicating the type of paged terminal in the Xn paging message) Base station B is one of the neighboring base stations of base station A, and base station A is the anchor base station of UE A.

[0118] In the prior art, the anchor base station knows the type of the inactive UE.

[0119] Referring to FIG. 13, the specific steps are as follows:

[0120] Step 0: UE A reports its terminal type to base station A, and the terminal type is a) 1rx RedCap terminal; b) 2rx RedCap terminals; c) Other than a) and b) above, the cell includes one of the following: and other terminals of a certain terminal type that the cell can prohibit from accessing by a broadcast message.

[0121] Step 1: When the anchor base station (base station A) pages the UE A, it sends a paging message (e.g., an N2 paging message) to the base station B within the UE location area, and indicates the type of the paged terminal in the paging message; Step 2: After receiving the paging message, the base station B transmits a paging message (for example, an air interface paging message) in a cell that allows the paged terminal to be located.

[0122] As can be appreciated, the above embodiment may also be used in LTE, for example, the N2 interface may be replaced by an S1 interface, and the Xn interface may be replaced by an X2 interface.

[0123] Example 3a Step 1: The gNB1 sends second information to the CN, indicating that the gNB1 supports RedCap UE; Step 2: The CN triggers a paging message for the UE A, and the CN sends a paging message to the gNB1 via the interface between the core network and the base station, where the paging message includes the identifier of the paged terminal and the type / capability of the paged terminal (for example: 1rx RedCap); Alternatively, if the paged terminal UE A is a 1rx RedCap UE, the CN may send an interface paging message between the core network and the base station only to gNBs that support RedCap.

[0124] Step 3: gNB1 sends a paging message including UE A's paging ID on the air interface of a cell under its control that allows 1rx RedCap coverage.

[0125] Example 3b Step 1: gNB1 sends second information to gNB2, indicating that gNB1 supports RedCap UE, where gNB2 is an anchor base station of gNB1; Step 2: gNB2 triggers a paging message for UE A, and gNB2 sends an inter-base station interface paging message to gNB1, where the paging message includes an identifier of the paged terminal and a type of the paged terminal (for example: 1rx RedCap); Alternatively, if the paged terminal UE A is a 1rx RedCap UE, gNB2 may send an inter-base station interface paging message only to gNBs that support RedCap.

[0126] Step 3: gNB1 sends a paging message including the terminal ID on the air interface of a cell under its control that allows 1rx RedCap coverage.
