Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and more specifically, to methods, terminal devices, and network devices for paging. Background Technology

[0002] With the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the growing diversity and complexity of services in the future, the 3rd Generation Partnership Project (3GPP) international standards organization began developing fifth-generation mobile communication technology (5G). The main application scenarios for 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communication (URLLC), and Massive Machine-Type Communication (mMTC).

[0003] In the early deployment of 5G New Radio (NR), 5G NR User Equipment (UE) is similar to Long Term Evolution (LTE) UEs. First, it attaches and registers with the core network. The core network then stores the UE's context information, including its Location Area List (TA list). When a paging request for the UE is received, the core network sends paging messages to all base stations listed in the TA list, triggering these base stations to send paging messages to all cells within their respective TA lists. Therefore, the paging range for a UE is at least the sum of all cells within a TA list that send paging messages.

[0004] In 5G NR, because cells use a multi-beam configuration, a paging message must be sent in each beam of each cell to page a UE. For a high-frequency cell, there are even more beams, such as 64, resulting in 64 paging transmissions within a single cell. This increases the network signaling load. To address this, the standard proposes a scheme to reduce paging signaling load: a paging indication-based scheme. Each UE is assigned a paging indication, with multiple UEs corresponding to one paging indication. Each UE first receives the paging indication; if it recognizes its paging message, it initiates a RACH procedure to request the base station to send the paging message. Therefore, there may be multiple paging schemes in the future, while traditional paging schemes will likely be retained.

[0005] Therefore, how the UE can distinguish which paging scheme is being used in the current cell is an urgent problem to be solved. Summary of the Invention

[0058] Figure 1 This is a schematic diagram illustrating an application scenario of an embodiment of the present invention.

[0059] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0060] It should be understood that the embodiments of the present invention are only illustrated by way of example with communication system 100, but the embodiments of the present invention are not limited thereto. That is to say, the technical solutions of the embodiments of the present invention can be applied to various communication systems, such as: Global System for Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), etc.

[0061] Furthermore, the present invention describes various embodiments in conjunction with network devices and terminal devices.

[0062] Network equipment 120 can refer to any entity on the network side used to transmit or receive signals. For example, it can be user equipment for machine-type communications (MTC), a base station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, or base station equipment in a 5G network.

[0063] Terminal device 110 can be any terminal device. Specifically, terminal device 110 can communicate with one or more core networks via a radio access network (RAN), and can also be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. For example, it can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, and terminal device in a 5G network, etc.

[0064] It is understandable that when communication system 100 includes a 5G New Radio (NR) communication system, such as in a hybrid deployment scenario consisting of a 5G communication system and a first communication system, etc., the first communication system can be any type of communication system. Examples include: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc. Similar to LTE UEs, 5G NR User Equipment (UE) first attaches and registers with the core network. The core network then stores the UE's context information, including its Location Area List (TA list). When a paging request for the UE is received, the core network sends paging messages to all base stations within the TA list, triggering these base stations to send paging messages to all cells within that base station. Therefore, the paging range for a UE is at least the range of all cells within a TA list.

[0065] However, in 5G NR, because cells use a multi-beam configuration, a paging message must be sent in each beam of each cell to page the UE. For a high-frequency deployed cell, there are even more beams, for example, 64, resulting in 64 paging transmissions within a single cell. This increases the network signaling load. To address this, the standard proposes a scheme to reduce the paging signaling load: a paging indication-based scheme. Each UE is assigned a paging indication, with multiple UEs corresponding to one paging indication. Each UE first receives the paging indication; if it believes it has a paging message, it initiates a Random Access Channel (RACH) procedure to request the base station to send a paging message. Therefore, there may be multiple paging schemes in the future, and traditional paging schemes will continue to be retained. Thus, how the UE distinguishes which paging scheme is being used in the current cell is a pressing issue that needs to be addressed.

[0066] To address the aforementioned technical problems, this invention provides a paging method that enables terminal devices to distinguish the paging mode used by the current cell of the terminal device.

[0067] Figure 2 This is a schematic flowchart of a paging method according to an embodiment of the present invention.

[0068] Specifically, such as Figure 2 As shown, the method includes:

[0069] 210. The network device generates indication information, which is used to indicate the paging method used by the terminal device in the current cell.

[0070] 220, the network device sends the instruction information to the terminal device.

[0071] 230. The terminal device obtains the paging message according to the instruction information.

[0072] Specifically, when the core network (CN) sends a paging message to the access network, it sends the paging message to all access network devices, such as the Radio Network Controller (RNC), within the routing area or local location area where the UE is located. Upon receiving the message, the access network devices then send a paging message to the UE in all cells within the access network. In this embodiment of the invention, the network device indicates the paging method used by the current cell of the terminal device through indication information. This enables the terminal device to distinguish the paging method used by its current cell before receiving the paging message, thereby correctly decoding the paging-related information and correctly obtaining the paging message.

[0073] It should be understood that the paging method involved in the embodiments of the present invention includes, but is not limited to, the following paging methods:

[0074] First paging method and second paging method.

[0075] The first paging method refers to: the core network device triggers the access network device to send a paging message, and the paged terminal device is identified by the System Architecture Evolution Temporary Mobile Subscriber Identity (SAE-TMSI); the second paging method refers to: the core network device triggers the access network device to send a paging message, and the paged terminal device is identified by the Paging indicator (PI).

[0076] In the embodiments of the present invention, the terms "first" and "second" are merely used to distinguish different paging methods and do not impose any other limitations on the embodiments of the present invention.

[0077] It should also be understood that the above descriptions of the first paging method and the second paging method are merely exemplary, and the embodiments of the present invention are not limited thereto.

[0078] For example, in this embodiment of the invention, the paged terminal device can also be identified by International Mobile Subscriber Identity (IMSI), Temporary IMSI (TIMSI), Packet-Temporary Mobile Subscriber Identity (P-TMSI), or International Mobile Equipment Identity (IMEI).

[0079] The following is an exemplary description of how the instruction information is sent or received. It should be understood that the way the network device sends the instruction information to the terminal device is similar to the way the terminal device receives the instruction information. To avoid repetition, the following example illustrates how the terminal device receives the instruction information:

[0080] In one embodiment, the terminal device receives System Information (SI) sent by the network device, which may include the indication information. In other words, the network device sends the indication to the UE via system broadcast. The UE obtains the paging method indication information by reading the system broadcast, and then obtains the paging message.

[0081] In another embodiment, the terminal device receives a Physical Downlink Control Channel (PDCCH) scrambled with a Paging Radio Network Temporary Identifier (P-RNTI) sent by the network device. This PDCCH may include the indication information. In other words, the network device uses the P-RNTI-scrambled PDCCH to carry an indication of the paging method for the terminal device's current cell. This allows the terminal device to obtain the paging method by decoding the P-RNTI-scrambled PDCCH before receiving the paging message, and thus obtain the paging message.

[0082] Furthermore, the PDCCH may also include scheduling information for the paging message.

[0083] Specifically, the scheduling information in this embodiment of the invention can be used to indicate the resource location of the paging message on the Physical Downlink Shared Channel (PDSCH), thereby enabling the terminal device to receive the paging message based on the resource location.

[0084] In another embodiment, the terminal device can receive a first message sent by the network device, the first message including the indication information and the paging message; wherein, the terminal device obtains the paging message in the first message according to the indication information. That is, the network device carries an indication of the paging method in the paging message. Furthermore, the terminal device can obtain the paging method and the corresponding paging content by decoding the paging message.

[0085] It should be understood that the above-mentioned methods of sending or receiving instruction information are merely exemplary descriptions, and the embodiments of the present invention are not limited thereto.
