Paging negotiation method and device, communication equipment and storage medium

Abstract

The embodiment of the invention provides a paging negotiation method, which comprises the following steps that: a first node sends auxiliary information to a second node, and the auxiliary information is used for indicating access layer capability. Since the auxiliary information sent to the second node by the first node indicates the access layer capability, the second node can send the paging message to the first node based on the access layer capability after receiving the auxiliary information, so that the sending of the paging message can be adapted to the access layer capability, and the paging message can be sent to the second node based on the access layer capability. Compared with a mode of always sending the paging message under the condition that the access layer capability is not determined, unnecessary signaling overhead can be saved.

Description

Paging negotiation method, device, communication equipment and storage medium Technical Field

[0001] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to a paging negotiation method, apparatus, communication device, and storage medium. Background Art

[0002] In wireless network communication technology, when the core network needs to send data to the terminal, it will send a paging message to the base station. The base station sends a paging message in the cell belonging to the Tracking Area (TA) list sent by the core network. The terminal receives the paging message sent by the base station at the paging opportunity. In the related art, a new terminal type called Reduced Capability UE (RedCap) or NR-lite for short is proposed. The main technical features of this terminal are reduced bandwidth and reduced receiving antennas. In a scenario, if the base station does not support the access of a certain type of terminal, then if this type of terminal cannot reside, the core network will continue to send paging messages to the user within the TA range. This will increase unnecessary signaling overhead between the core network and the base station.

[0144] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on mobile communication technology, and the wireless communication system may include: a plurality of user equipments 110 and a plurality of base stations 120.

[0145] The user equipment 110 may refer to a device that provides voice and / or data connectivity to a user. The user equipment 110 may communicate with one or more core networks via a radio access network (RAN). The user equipment 110 may be an Internet of Things user device, such as a sensor device, a mobile phone, and a computer with an Internet of Things user device. For example, the user equipment 110 may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote user device, an access terminal, a user terminal, a user agent, a user device, or user equipment. Alternatively, the user equipment 110 may be a device of an unmanned aerial vehicle.

Alternatively, the user equipment 110 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0146] The base station 120 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as a long-term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of the 5G system.

[0147] Among them, the base station 120 can be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station 120 can also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 120 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the base station 120.

[0148] A wireless connection can be established between the base station 120 and the user equipment 110 via a wireless air interface. In various implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0150] Here, the above user equipment can be considered as the terminal equipment in the following embodiments.

The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0153] To facilitate understanding by those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.

[0154] In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in the relevant technologies are described:

[0155] In one embodiment, when the core network needs to send data to a terminal, it sends a paging message to the base station. The base station sends the paging message to the cells that belong to the TA list in the paging message sent by the core network. The terminal receives the paging message sent by the base station at the paging opportunity. Typically, a TA may span multiple base stations or multiple cells under multiple base stations.

[0156] In one embodiment, the main technical features of the RedCap terminal are bandwidth reduction and the reduction of receiving antennas. Among them, the maximum bandwidth is as follows:

[0157] Frequency Range 1 (FR1): 20 MHz (uplink or downlink);

[0158] Second frequency range (FR2, Frequency Range 2): 100 MHz (uplink or downlink).

[0159] The number of antennas is as follows:

[0160] FR1 frequency division multiplexing: 1RX;

[0161] FR1 time division multiplexing: 2RX or 1RX;

[0162] FR2:2RX.

[0163] After the introduction of the RedCap terminal in version R18, the bandwidth was further reduced, as shown in Table 1, to 5 MHz or 20 MHz.

[0164] Table 1:

[0165]

[0166] If a base station does not support access by a certain type of terminal, for example, if the base station does not support access by the new Redcap user in R18, then this type of terminal cannot reside there. The core network is not sure of this and will continue to send paging messages for this user within the TA range. This will increase unnecessary signaling overhead between the core network and the base station. To reduce the occurrence of the above situation, negotiation of auxiliary information between base stations and between base stations and the core network can be considered. At the same time, the base station also needs to notify the core network of the access capability of the access layer (AS).

[0167] As shown in FIG2 , this embodiment provides a paging negotiation method, where the method is performed by a first node and includes:

[0168] Step 21: Send auxiliary information to the second node, where the auxiliary information is used to indicate access layer capabilities.

[0169] The nodes involved in this disclosure may be terminals, base stations, or network functions of a core network. For example, the first node is a base station, and the second node is a network function of a core network.

[0170] Here, the terminal involved in the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a road side unit (RSU), a smart home terminal, an industrial sensor device and / or a medical device, etc. In some embodiments, the terminal may be a predetermined version of a RedCap terminal (for example, an R17 version of a RedCap terminal or an R18 version of a RedCap terminal) or a predetermined version of a new air interface NR terminal (for example, an R17 NR terminal).

[0171] In one embodiment, auxiliary information is sent to the second node, wherein the auxiliary information is used to indicate access layer capabilities, wherein the access layer capabilities can be used to indicate: support for a predetermined type of terminal access or non-support for the predetermined type of terminal access. Here, the predetermined type of terminal can be an R18 RedCap terminal.

[0172] The R18 RedCap terminal can further differentiate antennas, for example, into a 1RX R18 RedCap terminal or a 2RX R18 RedCap terminal.

[0173] It should be noted that if the first node is a base station and the second node is a network function of the core network, the network function of the core network determines the access layer capability based on the auxiliary information after receiving the auxiliary information. If the auxiliary information indicates that the base station does not support the predetermined type of terminal to access the network, the network function of the core network will not send a paging call to the base station for the predetermined type of terminal. In this way, signaling overhead can be saved.

[0174] In one embodiment, in a non-UE-associated service process, the auxiliary information is sent to the second node; wherein the auxiliary information is used to indicate the access layer capability of the base station.
