[0066] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0067] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0068] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" 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, and B can be obtained through C; it can also mean that there is an association between A and B.

[0069] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0070] In the embodiments of the present application, "predefined" can be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (for example, a terminal and a network device), and the present application does not limit the specific implementation method. For example, predefined can refer to information defined in a protocol.

[0071] Currently, with people's pursuit of speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP (3rd Generation Partnership Project) international standards organization has begun developing 5G (5th Generation Mobile Communication Technology). The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), and Massive Machine Type Communications (mMTC).

[0072] eMBB still aims to provide users with multimedia content, services, and data, and demand for this technology is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it cannot be generalized and requires detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical characteristics of mMTC include high connection density, small data volumes, latency-insensitive services, low module costs, and long service life.

[0073] NR (New Radio) can also be deployed independently. To reduce air interface signaling and quickly restore wireless connections and data services in 5G networks, a new RRC (Radio Resource Control) state, the RRC INACTIVE state, is defined. This state is different from the RRC IDLE and RRC ACTIVE states.

[0074] RRC IDLE: Mobility is based on UE cell reselection. Paging is initiated by the CN (Core Network), and the paging area is configured by the CN. There is no UE AS (Access Stratum) context on the base station side. No RRC connection exists.

[0075] RRC CONNECTED: An RRC connection exists, and a UE AS context exists between the base station and the UE. The network locates the UE at the cell level. Mobility is controlled by the network. Unicast data can be transmitted between the UE and the base station.

[0076] RRC INACTIVE: Mobility is based on UE cell selection and reselection. There is a connection between CN and NR. The UE AS context exists on a certain base station. Paging is triggered by the RAN (Radio Access Network). The RAN-based paging area is managed by the RAN. The network side locates the UE at the RAN paging area level.

[0077] Please refer to FIG1 , which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 may include: a terminal 10 , an access network device 20 , and a core network device 30 .

[0078] The terminal 10 may refer to a user equipment (UE), 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 wireless communication device, a user agent, or a user device. Optionally, the terminal 10 may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in the fifth generation mobile communication system (5GS) or a terminal in the future evolved public land mobile communication network (PLMN), etc., and the embodiments of the present application are not limited to this. For the convenience of description, the above-mentioned devices are collectively referred to as terminals. The number of terminals 10 is usually multiple, and one or more terminals 10 can be distributed in each cell managed by the access network device 20.

[0079] The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal 10. The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR system, it is called gNodeB or gNB (next Generation Node B, next generation node B (or new generation access network node)). With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal 10 are collectively referred to as access network devices. Optionally, a communication relationship can be established between the terminal 10 and the core network device 30 through the access network device 20. For example, in a Long Term Evolution (LTE) system, the access network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs in the EUTRAN. In a 5G NR system, the access network device 20 may be a Radio Access Network (RAN) or one or more gNBs in the RAN. In the embodiments of the present application, unless otherwise specified, the network device referred to herein refers to the access network device 20, such as a base station.

[0080] The core network device 30 is a device deployed in the core network. The function of the core network device 30 is mainly to provide user connection, user management, and service carrying, and to provide an interface to the external network as a bearer network. For example, the core network equipment in the 5G NR system may include an access and mobility management function (AMF) network element, an authentication server function (AUSF) network element, a user plane function (UPF) network element, a session management function (SMF) network element, a location management function (LMF) network element, a policy control function (PCF) network element, a unified data management (UDM) network element, etc.

[0081] In one example, the access network device 20 and the core network device 30 communicate with each other via an interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal 10 communicate with each other via an air interface technology, such as the Uu interface.

[0082] Access network equipment is the device that allows terminals to access the network architecture wirelessly. It is primarily responsible for radio resource management, Quality of Service (QoS) management, data compression and encryption, etc. on the air interface side. Examples include NodeBs, evolved eNodeBs, base stations in 5G mobile communication systems or next-generation wireless (NR) communication systems, and base stations in future mobile communication systems.

[0083] The core network equipment includes NSSF (Network Slice Selection Function), AUSF (Authentication Server Function), UDM (Unified Data Management), AMF (Access and Mobility Management Function), SMF (Session Management Function), PCF (Policy Control Function), and UPF (User Plane Function).

[0084] The UE establishes an access layer connection with the (R)AN (Access Network) through the Uu interface, exchanging access layer messages and wireless data transmission. The UE establishes a non-access layer (None Access Stratum, NAS) connection with the AMF through the N1 interface, exchanging NAS messages. The AMF is the mobility management function in the core network, and the SMF is the session management function in the core network. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The PCF is the policy management function in the core network, responsible for formulating policies related to the mobility management, session management, and billing of the UE. The PCF transmits data with the external application function (AF) through the N5 interface. The UPF is a user plane function in the core network, which transmits data with the external data network (DN) through the N6 interface and with the AN through the N3 interface.

[0085] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems, and other communication systems such as Narrow Band Internet of Things (NB-IoT) systems, and this application does not limit this.

[0086] Please refer to Figure 2, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a terminal. The method includes the following steps.

[0087] Step 210: Send an uplink request signal, or determine whether to send an uplink request signal, where the uplink request signal is used to request to obtain public information of the first cell.

[0088] The uplink request signal may also be called an uplink wake-up signal (UpLink Wake Up Signal, UL WUS), a common information request signal, a SIB1 request signal or an energy-saving wake-up signal.

[0089] The uplink request signal is used to request public information of the first cell. Alternatively, the uplink request signal is used to request SIB1 of the first cell. Alternatively, the uplink request signal is used to request waking up the first cell. Alternatively, the uplink request signal is used to request the first cell to exit a power-saving state. Alternatively, the uplink request signal is used to request the first cell to exit an inactive state.

[0090] When the terminal needs to execute a communication process related to the first cell and the terminal has not obtained the public information of the first cell, the terminal may execute step 210 to send an uplink request signal, or determine whether to send an uplink request signal, so as to obtain the public information of the first cell and execute the communication process related to the first cell.

[0091] The first cell is a cell that does not send or does not actively send public information. Alternatively, the first cell is a cell that does not send or does not actively send SIB1. Alternatively, the first cell is a cell that does not send or does not actively send SIB (System Information Block).

[0093] The first cell may include at least one of the following: a SIB1less (lacking SIB1) cell, an NES (Network Energy Saving) cell, an inactive cell, an energy-saving cell, and a cell lacking public information.

[0094] Among them, the cell in the inactive state / energy-saving state can be called SIB1less cell, NES cell, inactive cell, energy-saving cell, or cell lacking public information; or, the cell that supports switching to the inactive state / energy-saving state can be called SIB1less cell, NES cell, inactive cell, energy-saving cell, or cell lacking public information.

[0095] Optionally, the first cell may have multiple cell states / network states. For example, the cell state / network state includes at least one of the following: an activated state, an inactivated state, an energy-saving state, and a non-energy-saving state.

[0096] Among them, a cell in an activated state or a non-energy-saving state can normally send common information / SIB1 / SIB, or a cell in an activated state or a non-energy-saving state can periodically send common information / SIB1 / SIB. That is, the activated state or the non-energy-saving state means that the cell can normally send common signals / SIB1 / SIB, or the cell can periodically send common signals / SIB1 / SIB.

[0097] A cell in an inactive state / energy-saving state does not send common information / SIB1 / SIB, or a cell in an inactive state / energy-saving state does not proactively send common information / SIB1 / SIB. In other words, the inactive state / energy-saving state means that the cell does not send or does not proactively send common information / SIB1 / SIB.

[0098] Optionally, the first cell is currently in an inactive state or an energy-saving state; or, the first cell is ready to switch from an active state / non-energy-saving state to an inactive state or an energy-saving state.

[0102] Optionally, the terminal is in an RRC idle state, or the terminal is in an RRC inactive state.

[0103] Optionally, the terminal currently resides in the first cell (NES cell); or, the terminal currently resides in the anchor cell of the first cell (a cell associated with the first cell); or, the terminal currently resides in other cells, which are cells other than the first cell and the anchor cell of the first cell.

[0104] Optionally, since the terminal cannot obtain the public information of the first cell, it cannot select the first cell to reside; the terminal resides in the cell according to at least one of the following methods: before the first cell sends public information, it does not reside in the first cell; before the first cell sends public information, it resides in the anchor cell of the first cell; before the first cell sends public information, it resides in other cells; other cells include cells other than the first cell and the anchor cell; before the first cell wakes up, it does not reside in the first cell; before the first cell wakes up, it resides in the anchor cell of the first cell; before the first cell wakes up, it resides in other cells; other cells include cells other than the first cell and the anchor cell; after the first cell sends public information, it resides in the first cell; after the first cell wakes up, it resides in the first cell.

[0105] Alternatively, the terminal may pre-camp on the first cell without acquiring the public information of the first cell, and then determine whether it can camp on the first cell after acquiring the public information of the first cell. That is, the terminal may camp on the first cell before the first cell sends the public information; and / or camp on the first cell after the first cell sends the public information; and / or camp on the first cell before the first cell wakes up; and / or camp on the first cell before the first cell wakes up.

[0106] Optionally, the terminal sends an uplink request signal to the target cell. The target cell may be at least one of the following: the first cell, an anchor cell of the first cell, or a cell where the terminal resides. The cell where the terminal resides may be the first cell, an anchor cell of the first cell, or another cell. The other cell is a cell other than the first cell or the anchor cell of the first cell.

[0107] The anchor cell of the first cell is a cell associated with the first cell. The information indicating the association relationship between the first cell and the anchor cell may be predefined, or may be indicated by the cell last accessed by the terminal, or by the last serving cell of the terminal, or by the serving cell of the terminal, or by the anchor cell of the first cell, or by the camped cell of the terminal, or by the first cell.

[0108] In summary, the method provided in this embodiment involves a terminal sending an uplink request signal to the network, requesting the first cell to send public information, thereby waking up the first cell to send public information (e.g., SIB1), and executing a communication process with the first cell based on the public information. This method provides a method for terminals to operate in cells that do not send or actively send public information, thereby improving the communication process within network energy-saving cells.

[0109] Please refer to Figure 3, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a network device. The method includes the following steps.

[0110] Step 310: Receive an uplink request signal, where the uplink request signal is used to request public information of the first cell.

[0111] Optionally, this embodiment is performed by a network device, which may be at least one of the following devices: an access network device of the first cell, an access network device of the anchor cell of the first cell, an access network device of the resident cell of the terminal, or a core network device.

[0112] Alternatively, the network device may be an access network device or a core network device of the target cell. The target cell includes at least one of the following: a first cell, an anchor cell of the first cell, a cell where the terminal resides, or another cell. The cell where the terminal resides may be the first cell, an anchor cell of the first cell, or another cell. Another cell is a cell other than the first cell or the anchor cell of the first cell.

[0113] The following describes various situations of network equipment.

[0114] (1) As shown in FIG4 , the network device may be a core network device.

[0115] Terminal 10 sends an uplink request signal to the access network device of second cell 40. Second cell 40 can be at least one of the following: an anchor cell of the first cell, a cell where the terminal resides, or another cell. The access network device of second cell 40 reports the uplink request signal to core network device 30. Core network device 30 forwards the uplink request signal to the access network device of first cell 50.

[0116] Optionally, the core network device 30 may also send other signals / messages / indication information to the first cell 50 to instruct the first cell 50 to send public information. For example, the core network device 30 may send uplink indication information to the first cell 50, where the uplink indication information is used to instruct the first cell to send public information / SIB1 / SIB.

[0117] Optionally, the core network device 30 triggers the first cell 50 to send common information / SIB1 / SIB.

[0118] (2) As shown in FIG5 , the network device may be an access network device of a second cell other than the first cell (eg, an anchor cell of the first cell, a resident cell of the terminal, or other cells).

[0119] Terminal 10 sends an uplink request signal to the access network device of second cell 40. Second cell 40 can be at least one of the following: an anchor cell of the first cell, a cell where the terminal resides, or another cell. The access network device of second cell 40 forwards the uplink request signal to the access network device of first cell 50.

[0120] Optionally, the second cell 40 (an anchor cell of the first cell, a resident cell of the terminal, or other cell) triggers the first cell 50 to send the common information / SIB1 / SIB.

[0121] (3) As shown in FIG6 , the network device may be an access network device of the first cell.

[0122] The terminal 10 sends an uplink request signal to the access network device of the first cell 50 .

[0123] Optionally, the first cell 50 autonomously triggers the first cell 50 to send the common information / SIB1 / SIB.

[0124] Based on Figures 4, 5, and 6 above, when the terminal sends an uplink request signal to the second cell, the terminal may send the uplink request signal to the second cell through a random access procedure. For example, the uplink request signal may be carried in Msg1, Msg2, Msg3, or Msg4 of the random access procedure. Alternatively, the terminal may send the uplink request signal to the second cell after accessing the second cell. Alternatively, the terminal may send the uplink request signal to the second cell using the resources corresponding to the first preconfiguration.

[0125] Among them, the first pre-configuration can be the configuration information of the uplink request signal received in advance by the terminal, and the first pre-configuration is used to configure at least one of the following contents: time domain resources, frequency domain resources, preamble, physical random access resources, random access resources, and beam direction of the uplink request signal.

[0126] The first pre-configuration may be sent to the terminal by the anchor cell of the first cell, or by the cell in which the terminal is currently residing, or by the cell in which the terminal has historically resided, or by the second cell, or pre-defined or written by the protocol, or by the last cell serving the UE to the UE, or by the cell in which the UE last resided, or by the NES cell through other cells to the UE, or by the NES cell to the UE (such as in an enhanced MIB or SSB, or in other signals sent before Wake up). Optionally, the terminal saves the first pre-configuration.

[0127] Optionally, the first pre-configuration of the uplink request signal can be configured for the first cell, that is, the first pre-configuration is used to configure the uplink request signal of the first cell. When the terminal needs to request the public information of the first cell, the uplink request signal is sent to the second cell using the resources corresponding to the first pre-configuration. Optionally, the first pre-configuration can also be configured for all NES cells, that is, the first pre-configuration is used to configure the uplink request signal of the NES cell. When the terminal needs to request the public information of any NES cell, the uplink request signal can be sent to the second cell using the resources corresponding to the first pre-configuration. Optionally, the pre-configuration of the uplink request signal can also be configured for the second cell, that is, the UE can use the resources corresponding to the first pre-configuration to send the uplink request signal to the second cell regardless of which NES cell is triggered.

[0128] Based on the above-mentioned FIG. 4 , FIG. 5 and FIG. 6 , when the terminal sends an uplink request signal to the first cell, the terminal may send the uplink request signal to the first cell on the resources corresponding to the second pre-configuration.

[0129] Among them, the second pre-configuration can be the configuration information of the uplink request signal received in advance by the terminal, and the second pre-configuration is used to configure at least one of the following contents: time domain resources, frequency domain resources, preamble, physical random access resources, random access resources, and beam direction of the uplink request signal.

[0130] The second pre-configuration may be sent to the terminal by the anchor cell of the first cell, or by the cell in which the terminal is currently residing, or by the cell in which the terminal has historically resided, or may be pre-defined or written by the protocol, or by the last cell serving the UE to the UE, or by the cell in which the UE last resided to the UE, or by the NES cell through other cells to the UE, or by the NES cell to the UE (such as in an enhanced MIB or SSB, or in other signals sent before Wake up). Optionally, the terminal saves the second pre-configuration.

[0131] Optionally, the second pre-configuration of the uplink request signal can be configured for the first cell, that is, the second pre-configuration is used to configure the uplink request signal of the first cell, and when the terminal needs to request public information of the first cell, the uplink request signal is sent to the first cell using the resources corresponding to the first pre-configuration. Optionally, the second pre-configuration can also be configured for all NES cells, that is, the second pre-configuration is used to configure the uplink request signal of the NES cell, and when the terminal needs to send an uplink request signal to any NES cell (e.g., the first cell), the resources corresponding to the second pre-configuration can be used to send the uplink request signal to the corresponding NES cell (e.g., the first cell).

[0132] Optionally, after receiving the uplink request signal, the first cell 50 sends the common information / SIB1 / SIB. Optionally, the first cell 50 may broadcast the common information / SIB1 / SIB, or the first cell 50 may unicast the common information / SIB1 / SIB to the terminal.

[0133] Optionally, the terminal receives common information / SIB1 / SIB sent by the first cell.

[0134] Optionally, the terminal receives the common information / SIB1 / SIB sent by the first cell according to the common information configuration / SIB1 configuration / SIB configuration. The common information configuration / SIB1 configuration / SIB configuration is used to indicate the time-frequency resources of the common information / SIB1 / SIB.

[0135] Among them, the public information configuration / SIB1 configuration / SIB configuration can be carried in the SSB of the first cell, that is, the first cell sends the SSB, and the terminal receives the public information / SIB1 / SIB according to the public information configuration / SIB1 configuration / SIB configuration indicated in the SSB.

[0136] Alternatively, the common information configuration / SIB1 configuration / SIB configuration may be indicated to the terminal by the anchor cell of the first cell / the resident cell of the terminal / other cells / core network equipment.

[0137] Alternatively, the common information configuration / SIB1 configuration / SIB configuration may be predefined.

[0138] In summary, the method provided in this embodiment involves a terminal sending an uplink request signal to the network, requesting the first cell to send public information, thereby waking up the first cell to send public information (e.g., SIB1), and executing a communication process with the first cell based on the public information. This method provides a method for terminals to operate in cells that do not send or actively send public information, thereby improving the communication process within network energy-saving cells.

[0139] An exemplary embodiment is provided in which a terminal determines whether to send an uplink request signal.

[0140] Please refer to Figure 7, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a terminal. Based on the embodiment shown in Figure 2, step 210 includes step 211, step 212 and step 213.

[0141] Step 211: Determine whether to send an uplink request signal based on a trigger condition or a judgment factor.

[0142] The triggering condition or judgment factor is configured by the network, or is predefined, or is determined by the terminal implementation.

[0143] Optionally, the terminal may receive configuration information of the trigger condition or judgment factor sent by the first cell / an anchor cell of the first cell / a camped cell of the terminal / another cell. Alternatively, the configuration information of the trigger condition or judgment factor is predefined by a communication protocol. Alternatively, the configuration information of the trigger condition or judgment factor is determined by a preset algorithm within the terminal.

[0144] Optionally, the trigger condition or judgment factor may be configured by a core network device. The trigger condition or judgment factor may also be configured by an access network device; for example, the access network device of the first cell, the access network device of the anchor cell of the first cell, the access network device of the terminal's resident cell, the access network device of other cells, etc.

[0145] Optionally, the trigger condition includes at least one of the following: whether the first cell meets the cell selection condition; whether the first cell meets the cell reselection condition; the first cell meets the cell selection condition; the first cell meets the cell reselection condition; there is uplink data to be sent; the data volume of the uplink data is greater than or equal to the data volume threshold; the network instructs or enables the terminal to send an uplink request signal; the terminal obtains the SSB of the first cell, but does not obtain the SIB1 of the first cell; the terminal does not obtain the SIB1 of the first cell; the channel quality of the SSB of the first cell is greater than or equal to the quality threshold; the frequency priority of the first cell is higher than the frequency priority of other cells; other cells include the terminal's resident cell; the network instructs the terminal to access the first cell; the network instructs the terminal to perform a random access process; the network instructs the terminal to send an uplink request signal; the terminal receives a paging message; the terminal needs to transmit downlink data; the network instructs the terminal to access in the first cell; the network instructs the terminal to send an uplink request signal in the first cell.

[0146] Optionally, the judgment factors include at least one of the following: channel quality of the first cell; RSRP of the first cell; RSRQ of the first cell; network slices supported by the first cell; network slices supported by the frequency of the first cell; network slices required by the terminal; a list of cells allowed to be used; a list of cells not allowed to be used; data status of uplink data; data status of downlink data; paging information; reception status of SSB of the first cell; reception status of SIB1 of the first cell; frequency priority of the first cell; frequency priority of the terminal's resident cell; channel quality of the terminal's resident cell; whether the first cell is excluded; the first indication signal The first indication information is used to indicate that the terminal is allowed to send an uplink request signal, or the first indication information is used to indicate that the terminal is not allowed to send an uplink request signal; the second indication information, the second indication information is used to indicate the resident cell of the terminal, or to indicate that the terminal accesses the resident cell, or to indicate that the terminal sends an uplink request signal in the resident cell; the third indication information, the third indication information is used to indicate the access cell of the terminal, or to indicate that the terminal sends an uplink request signal in the access cell; the fourth indication information, the fourth indication information is used to indicate the target cell, or to indicate that the terminal sends an uplink request signal in the target cell, or to indicate that the terminal accesses the target cell.

[0147] Optionally, the terminal sends an uplink request signal when the first condition is met; and does not send an uplink request signal when the first condition is not met. Alternatively, the terminal sends an uplink request signal to a network device when the first condition is met; the network device may be an access network device of the target cell.

[0148] The first condition is related to a trigger condition or a judgment factor. The first condition is set based on the trigger condition and / or the first condition is set based on the judgment factor. For example, the first condition can be set to satisfy at least one of the trigger conditions, or the first condition can be set to satisfy at least one parameter of the judgment factor reaching a threshold value.

[0149] Optionally, the first condition is configured by the network, or is predefined, or is determined by the terminal implementation.

[0150] For example, Table 1 provides several examples of the first conditions.

[0151] Table 1

[0152] Step 212: Do not send an uplink request signal.

[0153] Optionally, the terminal does not send an uplink request signal if the first condition is not met.

[0154] Optionally, the terminal may perform a first behavior when the first condition is not met. The first behavior includes at least one of the following: entering the RRC idle state, such as executing any one of the items described in 3GPP TS (Technical Specification) 38.331 5.3.11; recording or indicating that the failure cause value is a failure to send an uplink request signal; stopping a first timer (T390 timer), the first timer being used for a cell reselection process; executing at least one of the UAC (Unified Access Control) behaviors, such as executing any one of the items described in 3GPP TS 38.3315.3.14.4; executing at least one of the RRC connection failure behaviors; and determining that a second timer has timed out, the second timer being used for an RRC connection establishment process.

[0155] Among them, the T390 timer is started after the UE receives the RRC connection release message, which is used to ensure that the UE has enough time to complete cell measurement and evaluation during the cell reselection process. When the UE fails to complete cell reselection within the T390 timer, the T390 timer expires, the UE will release the radio resources and enter the idle state. The T300 timer is started when the UE initiates an RRC connection request, which is used to ensure that the UE has enough time to interact with the EUTRAN (Evolved Universal Terrestrial Radio Access Network) during the RRC connection establishment process. If the UE fails to complete the RRC connection establishment within the T300 timer, the UE will release the radio resources and re-initiate the RRC connection request.

[0156] Step 213: Send an uplink request signal.

[0157] Optionally, the terminal sends an uplink request signal when the first condition is met. Alternatively, the terminal sends an uplink request signal to the target cell when the first condition is met.

[0158] In an optional embodiment, if the terminal does not trigger the sending of the uplink request signal, or the uplink request signal fails to be sent, or the uplink request signal fails to be responded to, the terminal may execute the first behavior.

[0159] That is, after step 210, the terminal may further perform at least one of the following steps:

[0160] In the case that the uplink request signal fails to be sent, executing the first behavior;

[0161] In the case where the first cell does not send the public information, performing a first action;

[0162] If the network does not indicate that the uplink request signal is received successfully, execute the first behavior; for example, if the target cell does not indicate that the uplink request signal is received successfully, execute the first behavior;

[0163] When the terminal determines that the uplink request signal triggering fails, executing the first behavior;

[0164] When the terminal determines that the uplink request signal request is unsuccessful, executing the first behavior;

[0165] When the terminal determines that the uplink request signal request is not responded to, the first behavior is executed.

[0166] Among them, the first behavior includes at least one of the following: entering the RRC idle state, such as executing any one of the items described in 3GPP TS 38.331 5.3.11; recording or indicating the failure cause value as failure to send an uplink request signal; recording or indicating the failure cause value as failure to respond to an uplink request signal; stopping the first timer (T390 timer), which is used for the cell reselection process; executing at least one of the UAC behaviors, such as executing any one of the items described in 3GPP TS 38.331 5.3.14.4; executing at least one of the RRC connection failure behaviors; determining that the second timer (T300 timer) has timed out, which is used for the RRC connection establishment process; executing at least one behavior of the T300 timer timeout.

[0167] In summary, the method provided in this embodiment allows the terminal to determine whether to send an uplink request signal based on a trigger condition or judgment factor, and to send an uplink request signal to the network when the first condition is met, and not to send an uplink request signal when the first condition is not met. In this way, the terminal can send an uplink request signal to the network, requesting the first cell to send public information, so as to wake up the first cell to send public information (such as SIB1), and execute the communication process with the first cell based on the public information. This method provides a working mode for the terminal in a cell that does not send or does not actively send public information, and improves the communication process within the network energy-saving cell.

[0168] The method provided in this embodiment provides a processing method when an uplink request signal fails to be sent, thereby improving the working method of the terminal in a network energy-saving cell.

[0169] An exemplary embodiment is provided in which a terminal determines to send an uplink request signal on a target cell.

[0170] Please refer to FIG8 , which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a terminal.

[0171] Optionally, step 230 may also be implemented independently as an embodiment.

[0172] Optionally, step 230 may also be implemented in combination with the embodiment shown in FIG2 as at least one embodiment. For example: the terminal determines to send an uplink request signal in the target cell; the terminal sends an uplink request signal to the target cell. Alternatively, the terminal determines to send an uplink request signal in the target cell; the terminal determines whether to send an uplink request signal; if it is determined to send an uplink request signal, the uplink request signal is sent to the target cell; if it is determined not to send an uplink request signal, the uplink request signal is not sent. Alternatively, the terminal determines whether to send an uplink request signal; if it is determined to send an uplink request signal, the terminal continues to determine to send an uplink request signal on the target cell; then sends an uplink request signal to the target cell; if it is determined not to send an uplink request signal, the terminal does not send an uplink request signal.

[0173] Optionally, step 230 may be combined with at least one step in the embodiment shown in FIG7 to implement at least one embodiment. Step 230 may be performed before or after step 211. For example, the terminal may determine the target cell by performing step 230 after determining that the first condition is satisfied. The terminal may also determine the target cell by performing step 230 after determining that the first condition is satisfied.

[0174] Step 230: Determine to send an uplink request signal in the target cell.

[0175] The target cell is predefined, or the target cell is indicated by the network, or the target cell is determined by the terminal.

[0176] For example, the indication information of the target cell may be predefined in the communication protocol.

[0177] For another example, the last access cell (last serving cell) of the terminal may send indication information of the target cell to the terminal (for example, carried in an RRC connection release message, or carried in an RRC message, carried in system information, or carried in other messages). Alternatively, the resident cell of the terminal may send indication information of the target cell to the terminal (for example, carried in system information, or carried in a message of a random access process). Alternatively, the anchor cell of the first cell may send indication information of the target cell to the terminal (for example, carried in system information, or carried in a message of a random access process). Alternatively, the first cell may send indication information of the target cell to the terminal (for example, carried in an SSB).

[0178] For another example, the target cell is determined according to an algorithm preset in the terminal.

[0179] Optionally, the target cell includes: a resident cell of the terminal, or an anchor cell of the first cell, or the first cell. The resident cell of the terminal may include at least one of the following: the first cell, an anchor cell of the first cell, or other cells, where the other cells include cells other than the first cell and the anchor cell.

[0180] Optionally, the terminal may send an uplink request signal if the first condition is met; or, send an uplink request signal to the target cell; or, send an uplink request signal to the target cell if the first condition is met.

[0181] Optionally, when the terminal sends an uplink request signal to the second cell, the second cell may forward the uplink request signal to the first cell so that the first cell can respond to the uplink request signal. For example, the second cell may forward the uplink request signal to the first cell via a core network device, or the second cell may directly forward the uplink request signal to the first cell. The second cell includes the anchor cell of the first cell, the resident cell of the terminal, and other cells.

[0182] In summary, the method provided in this embodiment allows the terminal to send an uplink request signal to the target cell. The target cell can be the first cell or a second cell other than the first cell, and the second cell forwards the uplink request signal to the first cell. The first cell is then requested to send public information to wake up the first cell to send public information (such as SIB1), and the communication process with the first cell is executed based on the public information. This method provides a working mode for the terminal in a cell that does not send or does not actively send public information, and improves the communication process within the network energy-saving cell.

[0183] An exemplary embodiment is provided in which a terminal monitors a paging message of a first cell.

[0184] Please refer to FIG9 , which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a terminal.

[0185] Optionally, step 240 may also be implemented independently as an embodiment.

[0186] Optionally, step 240 may also be implemented as at least one embodiment in combination with the embodiment shown in Figure 2. The order in which the steps are executed may be arbitrary.

[0187] Optionally, step 240 may be combined with at least one step in the embodiment shown in Figure 7 to form at least one embodiment. The order in which the steps are executed may be arbitrary.

[0188] Optionally, step 240 can be implemented in combination with the embodiment shown in Figure 8 to form at least one embodiment. The order in which the steps are executed can be arbitrary.

[0189] Step 240: Monitor the paging message of the first cell, or perform paging monitoring in the first cell.

[0190] For example, the embodiments of the present application provide two types of methods for monitoring paging messages of the first cell: a first type: monitoring based on public information of the first cell; and a second type: monitoring based on a first paging configuration. The terminal can monitor the paging messages of the first cell in at least one of the two types of methods.

[0191] Category 1: The terminal monitors paging messages in the first cell based on the public information of the first cell; or monitors paging messages in the cell based on the paging search space configuration indicated by the first cell; the public information includes the paging search space configuration. Alternatively, the terminal monitors paging messages in the first cell based on the public information of the first cell; or monitors paging messages in the first cell based on the paging search space configuration indicated by the first cell.

[0192] Optionally, the public information of the first cell includes a paging search space configuration of the paging message, and the terminal may monitor the paging message of the first cell according to the time-frequency position indicated by the paging search space configuration.

[0193] Optionally, when monitoring is performed using the first type of method, the terminal needs to first receive public information from the first cell. The sending of the public information is triggered by at least one of the following devices: a core network device, an access network device of an anchor cell of the first cell, an access network device of a cell where the terminal resides, or an access network device of the first cell.

[0194] Optionally, the terminal may trigger the first cell to send public information by using the method provided in any one of the embodiments described in FIG. 2 to FIG. 8 .

[0195] Category 2: monitoring the paging message of the first cell according to the first paging configuration, or performing paging monitoring in the first cell according to the first paging configuration; wherein the first paging configuration includes at least one of the following: the first paging configuration is predefined; the first paging configuration is obtained from the cell last accessed by the terminal; the first paging configuration is obtained from the last serving cell of the terminal; the first paging configuration is obtained from the anchor cell of the first cell; the first paging configuration is obtained from the resident cell of the terminal.

[0196] When monitoring using the second method, the terminal does not need to obtain the public information of the first cell. Of course, the terminal may also obtain the public information of the first cell, but the public information does not carry the paging search space configuration. Alternatively, the terminal may obtain the public information of the first cell, and the public information carries the paging search space configuration, but the first paging configuration has a higher priority than the paging search space configuration. In this case, the terminal will preferentially use the first paging configuration to monitor the paging message of the first cell.

[0197] The first paging configuration is used to configure a search space for paging messages of the first cell. The first paging configuration may be predefined by a communication protocol. Alternatively, the first paging configuration may be configured by a network device to the terminal. The network device may be at least one of the following: an access network device of the terminal's last accessed cell, an access network device of the terminal's last serving cell, an access network device of the first cell's anchor cell, an access network device of the terminal's resident cell, or a core network device.

[0198] Optionally, the terminal may first request to obtain public information of the first cell. If the terminal obtains the public information of the first cell, the terminal may monitor the paging message of the first cell according to the public information. If the terminal does not obtain the public information of the first cell, the terminal may monitor the paging message of the first cell according to the first paging configuration.

[0199] For example, if the public information of the first cell is not obtained, the terminal may send a paging configuration acquisition request to the resident cell or the anchor cell of the first cell, where the paging configuration acquisition request is used to request the first paging configuration. The resident cell or the anchor cell may send the first paging configuration to the terminal.

[0200] Alternatively, the first paging configuration is pre-acquired by the terminal (for example, pre-configured to the terminal by the last access cell / last serving cell / anchor cell / resident cell). If the public information of the first cell is not obtained, the terminal can directly use the first paging configuration to monitor the paging message of the first cell.

[0201] The terminal may also not request to obtain the public information, but directly monitor the paging message of the first cell according to the first paging configuration. That is, the terminal may not send an uplink request signal to request to obtain the public information.

[0202] Correspondingly, the access network device of the first cell sends a paging message according to the public information. Alternatively, the access network device of the first cell sends a paging message according to the paging search space in the public information. Alternatively, the access network device of the first cell sends a paging message according to the first paging configuration.

[0203] In summary, the method provided in this embodiment allows a terminal to monitor paging messages from the first cell based on the first cell's public information, or to monitor paging messages from the first cell based on the first paging configuration. This method provides a method for operating a terminal in a cell that does not transmit or actively transmit public information, thereby improving the communication process within a network energy-saving cell.

[0204] An exemplary embodiment is given in which a terminal responds to a paging message of a first cell.

[0205] Please refer to FIG10 , which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a terminal.

[0206] Optionally, step 250 may also be implemented independently as an embodiment.

[0207] Optionally, step 250 may also be implemented as at least one embodiment in combination with the embodiment shown in Figure 2. The order in which the steps are executed may be arbitrary.

[0208] Optionally, step 250 may be combined with at least one step in the embodiment shown in Figure 7 to form at least one embodiment. The order in which the steps are executed may be arbitrary.

[0209] Optionally, step 250 can be combined with the embodiment shown in Figure 8 to implement at least one embodiment. The order in which the steps are executed can be arbitrary.

[0210] Optionally, step 250 can be combined with the embodiment shown in FIG9 to implement at least one embodiment. Step 240 is performed before step 250. For example, the terminal may monitor the paging message based on the public information and then respond to the paging message based on the public information. The terminal may also monitor the paging message based on the public information and respond to the paging message based on the first random access configuration. The terminal may also monitor the paging message based on the first paging configuration and respond to the paging message based on the public information. The terminal may also monitor the paging message based on the first paging configuration and respond to the paging message based on the first random access configuration.

[0211] Step 250: In the first cell, respond to the paging message of the first cell.

[0212] For example, the embodiments of the present application provide two types of methods for responding to a paging message from a first cell: a first type: a response based on public information of the first cell; and a second type: a response based on a first random access configuration. The terminal may respond to the paging message from the first cell in at least one of the two types of methods.

[0213] Category 1: The terminal can respond to the paging message by performing at least one of the following methods:

[0214] responding to the paging message based on the public information of the first cell;

[0215] performing a random access procedure based on the public information of the first cell;

[0216] Accessing the first cell based on the public information of the first cell;

[0217] Respond to the paging message based on the random access configuration indicated by SIB1 in the public information;

[0218] Perform a random access procedure based on the random access configuration indicated by SIB1 in the public information;

[0219] Access the first cell based on the random access configuration indicated by SIB1 in the public information.

[0220] That is, the manner in which the terminal responds to the paging message may include at least one of the following: sending a response message to the paging message to the first cell; performing a random access procedure to access the first cell; and accessing the first cell.

[0221] Optionally, the public information of the first cell includes a random access configuration, and the terminal may initiate a random access procedure to access the first cell according to the random access configuration. After accessing the first cell, the terminal may send a response message to the paging message to the first cell. Alternatively, the first cell may send a response message to the paging message to the first cell through a random access procedure according to the random access configuration.

[0222] Optionally, when monitoring is performed using the first type of method, the terminal needs to first receive public information from the first cell. The sending of the public information is triggered by at least one of the following devices: a core network device, an access network device of an anchor cell of the first cell, an access network device of a cell where the terminal resides, or an access network device of the first cell.

[0223] Optionally, the terminal may trigger the first cell to send public information by using the method provided in any one of the embodiments described in FIG. 2 to FIG. 8 .

[0224] Category 2: The terminal can respond to the paging message by performing at least one of the following methods:

[0225] responding to the paging message based on the first random access configuration;

[0226] performing a random access procedure based on the first random access configuration;

[0227] Accessing the first cell based on the first random access configuration;

[0228] The first random access configuration includes at least one of the following: the first random access configuration is predefined; the first random access configuration is obtained from the last accessed cell of the terminal; the first random access configuration is obtained from the last serving cell of the terminal; the first random access configuration is obtained from the anchor cell of the first cell; the first random access configuration is obtained from the resident cell of the terminal.

[0229] When responding to a paging message using the second method, the terminal does not need to obtain the public information of the first cell. Of course, the terminal may also obtain the public information of the first cell, but the public information does not carry the random access configuration. Alternatively, the terminal may obtain the public information of the first cell, and the public information carries the random access configuration. If the first random access configuration has a higher priority than the random access configuration in the public information, the terminal will preferentially use the first random access configuration to respond to the paging message.

[0230] The first random access configuration is used to configure random access resources for the first cell. The first random access configuration may be predefined by a communication protocol. Alternatively, the first random access configuration may be configured by a network device to the terminal. The network device may be at least one of the following: an access network device of the terminal's last accessed cell, an access network device of the terminal's last serving cell, an access network device of the first cell's anchor cell, an access network device of the terminal's resident cell, or a core network device.

[0231] Optionally, the terminal may first request to obtain public information of the first cell. If the terminal obtains the public information of the first cell, the terminal may respond to the paging message of the first cell based on the public information. If the terminal does not obtain the public information of the first cell, the terminal may respond to the paging message of the first cell based on the first random access configuration.

[0232] For example, if the public information of the first cell is not obtained, the terminal may send a random access configuration acquisition request to the resident cell or the anchor cell of the first cell, where the random access configuration acquisition request is used to request the first random access configuration. The resident cell or the anchor cell may send the first random access configuration to the terminal.

[0233] Alternatively, the first random access configuration is pre-acquired by the terminal (for example, pre-configured to the terminal by the last access cell / last serving cell / anchor cell / resident cell). If the public information of the first cell is not obtained, the terminal can directly use the first random access configuration to respond to the paging message of the first cell.

[0234] The terminal may also respond to the paging message of the first cell directly according to the first random access configuration without requesting to obtain the public information. That is, the terminal may not send an uplink request signal to request to obtain the public information.

[0235] Correspondingly, the access network device of the first cell receives a response message to the paging message based on the public information. Alternatively, the access network device of the first cell receives a random access message from the terminal based on the public information. Alternatively, the access network device of the first cell receives a response message to the paging message based on the random access configuration in the public information. Alternatively, the access network device of the first cell receives a random access message from the terminal based on the random access configuration in the public information. Alternatively, the access network device of the first cell receives a response message to the paging message based on the first random access configuration. Alternatively, the access network device of the first cell receives a random access message from the terminal based on the first random access configuration.

[0236] In summary, the method provided in this embodiment allows a terminal to respond to a paging message from the first cell based on the first cell's public information. Alternatively, the terminal can respond to a paging message from the first cell based on the first random access configuration. This method provides a method for operating a terminal in a cell that does not transmit or actively transmit public information, improving the communication process within a network energy-saving cell.

[0237] Optionally, referring to the embodiments shown in FIG. 2 to FIG. 10 , when the first cell does not send or does not actively send public information, the first cell may not send indication information to the terminal to inform of this situation.

[0238] At this time, the terminal can determine that the first cell does not send or does not actively send public information based on the monitoring situation of the first cell (for example, the public information of the first cell is not received). The terminal can also determine that the first cell does not send or does not actively send public information based on the cell type of the first cell (for example, the first cell is an NES cell or a SIB1less cell). The terminal can also determine that the first cell does not send or does not actively send public information based on the instructions of the terminal's resident cell / the anchor cell of the first cell / other cells. The terminal can also communicate with the first cell directly according to the instructions of the network side without determining that the first cell does not send or does not actively send public information.

[0239] In addition, the first cell may also inform the terminal in advance that the first cell does not send or does not actively send public information. The following describes the situation in which the first cell informs the terminal in advance that the first cell does not send or does not actively send public information.

[0240] Please refer to Figure 11, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied in a terminal. The method includes the following steps.

[0241] Step 410: Receive first information of the first cell; wherein the first information is used to indicate at least one of the following: cell state change of the first cell; the first cell does not send public information; the first cell is converted to not sending public information; the first cell is converted to an inactive state; the first cell is converted to an energy-saving state.

[0242] Optionally, the terminal receives first information sent by the first cell.

[0243] Exemplarily, the first information is carried by system information, or by a dedicated RRC message.

[0244] Optionally, the first cell supports cell state switching: it can be switched from a non-energy-saving state to an energy-saving state; or, switched from an activated state to an inactivated state; or, switched from actively sending public information to not sending or not actively sending public information.

[0245] When the first cell is about to perform a cell state handover, first information may be broadcasted so that terminals in the first cell are informed of the cell state handover of the first cell. The first information is used to indicate the cell state handover of the first cell.

[0246] Optionally, the first information may include time information; wherein the time information includes at least one of the following: time information used to indicate the cell state transition time of the first cell; time information used to indicate the time when the first cell does not send public information; time information used to indicate the time when the first cell switches to not sending public information; time information used to indicate the time when the first cell is in an inactive state; time information used to indicate the time when the first cell is in an energy-saving state.

[0247] That is, the first cell may also inform the terminal of a time when the public information is not sent or not actively sent through the first information. The time information may be used to indicate at least one of the following: a start time (time point), an end time (time point), a duration, a duration period, a time offset corresponding to the start time, and a time offset corresponding to the end time.

[0248] After receiving the first information, the terminal may execute a communication process related to the first cell according to the first information.

[0249] Optionally, when the first cell undergoes another cell state switch, for example, from an energy-saving state to a non-energy-saving state; or from an inactive state to an active state; or from not sending or not actively sending public information to actively sending public information, the first cell may further send third information, where the third information is used to indicate at least one of the following: a cell state switch of the first cell; the first cell actively sending public information; the first cell switching to actively sending public information; the first cell switching to an active state; or the first cell switching to a non-energy-saving state. The terminal receives the third information of the first cell.

[0250] In summary, the method provided in this embodiment allows, for a first cell that does not send or does not proactively send public information, the first cell to send a first message, informing the terminal through the first message that the first cell does not send or does not proactively send public information, so that the terminal can execute the communication process based on the fact that the first cell does not send or does not proactively send public information. This method provides a working mode for a terminal in a cell that does not send or does not proactively send public information, and improves the communication process within a network energy-saving cell.

[0251] Please refer to Figure 12, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied to an access network device of a first cell. The method includes the following steps.

[0252] Step 510: Send first information of the first cell; wherein the first information is used to indicate at least one of the following: cell state change of the first cell; the first cell does not send public information; the first cell is converted to not sending public information; the first cell is converted to an inactive state; the first cell is converted to an energy-saving state.

[0253] Optionally, after the first cell sends the first information, at least one of the following methods may be executed: not sending public information; not actively sending public information; switching to not sending public information; switching to an inactive state; switching to an energy-saving state.

[0254] In summary, the method provided in this embodiment allows, for a first cell that does not send or does not proactively send public information, the first cell to send a first message, informing the terminal through the first message that the first cell does not send or does not proactively send public information, so that the terminal can execute the communication process based on the fact that the first cell does not send or does not proactively send public information. This method provides a working mode for a terminal in a cell that does not send or does not proactively send public information, and improves the communication process within a network energy-saving cell.

[0255] After receiving the first information, the terminal may also send second information to the first cell, and negotiate with the first cell on public information sending matters through the second information.

[0256] Please refer to Figure 13, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied to a terminal and an access network device of a first cell. Based on the embodiment shown in Figure 11 or Figure 12, after sending / receiving the first information, step 601 can also be included.

[0257] Step 601: The terminal sends second information.

[0258] The terminal sends the second information to the first cell, and the access network device of the first cell receives the second information sent by the terminal.

[0259] Among them, the second information is used to indicate at least one of the following: requesting the first cell not to change the cell state; requesting the first cell to send public information; requesting the first cell to continue to send public information; requesting the first cell not to enter the inactive state; requesting the first cell not to enter the energy-saving state; requesting the first cell to postpone entering the inactive state; requesting the first cell to postpone entering the energy-saving state; the terminal is stationed in the first cell; the inactive state time requested by the terminal; the non-energy-saving state time requested by the terminal; the active state time requested by the terminal; the energy-saving state time requested by the terminal; the time when the terminal is located in the first cell; the terminal is within the range of the first cell.

[0260] That is, the terminal may request the first cell not to perform cell state switching and request the first cell to continue to actively send public information through the second information.

[0261] The terminal may also indicate to the first cell, through the second information, an expected time (e.g., inactive state time, non-energy-saving state time, active state time, energy-saving state time) during which public information is not sent or not actively sent. The expected time may include at least one of the following: an expected start time (time point), an expected end time (time point), an expected time period, a time offset corresponding to the expected start time, and a time offset corresponding to the expected end time.

[0262] The terminal can also indicate the terminal status to the first cell through the second information. The terminal status can include the time when the terminal is located in the first cell (start time, end time, time period, time offset, etc.). The terminal status can also include whether the terminal is currently located within the range of the first cell.

[0263] The first cell may adjust the cell state according to the second information, or adjust the switching strategy of the cell state, so as to improve the communication efficiency between the first cell and the terminal.

[0264] For example, when the second information is used to indicate a request for the first cell not to change the cell state / request the first cell to send public information / request the first cell to continue sending public information / request the first cell not to enter the inactive state / request the first cell not to enter the energy-saving state / request the first cell to temporarily postpone entering the inactive state / the terminal resides in the first cell / the terminal is within the range of the first cell, the first cell may not perform cell state switching within the first time period, and after the first time period ends, continue to send the first information to indicate the execution of cell state switching.

[0265] Alternatively, when the second information is used to indicate the inactive state time requested by the terminal / the non-energy-saving state time requested by the terminal / the active state time requested by the terminal / the energy-saving state time requested by the terminal / the time when the terminal is located in the first cell, the first cell can perform cell state switching according to the time requested by the terminal / the indicated time.

[0266] Optionally, the terminal may determine whether to send the second information, and if it is determined to send the second information, send the second information, or if it is determined not to send the second information, not send the second information.

[0267] In summary, the method provided in this embodiment allows the terminal to, after receiving the first information, send the second information to the first cell to request the first cell not to perform a cell state handover, or to request the first cell to perform a cell state handover within a desired time, or to indicate the current state of the terminal to the first cell. This facilitates negotiation between the first cell and the terminal regarding the network state of the first cell, thereby improving communication between the first cell and the terminal.

[0268] After receiving the first information, the terminal may also perform cell reselection, or determine that the first cell is not allowed to be accessed, resided, or used.

[0269] Please refer to Figure 14, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied to a terminal and an access network device of a first cell. Based on the embodiment shown in Figure 11 or Figure 12, after sending / receiving the first information, step 602 can also be included.

[0270] Step 602: When the terminal is camped in the first cell, the terminal performs a cell reselection process, or reselects the cell where the terminal is camped, or the terminal determines that the first cell is not allowed to be accessed, camped on, or used.

[0271] Optionally, not allowing access, residing or using the first cell may mean that the first cell is not allowed to be accessed, not allowed to be resided or not allowed to be used. For example, the terminal determines that the first cell is unavailable, cannot be selected to reside, is prohibited, cannot be selected, and cannot be reselected.

[0272] Alternatively, the terminal determines that the first cell is not allowed to be accessed, resided on, or used within a second duration, which may be 300 seconds.

[0273] Optionally, after the terminal learns that the first cell does not send or does not actively send public information, the terminal reselects another cell to reside on, or reselects another cell to access.

[0274] For example, the terminal currently resides in the first cell. After receiving the first information, the terminal cannot continue to reside in the first cell, so the terminal performs cell reselection and reselects to reside in another cell.

[0275] In summary, the method provided in this embodiment allows a terminal to determine that the first cell is unavailable after receiving the first information. If the terminal is currently resident in the first cell, the terminal can reselect to reside in another cell. This method provides a method for operating a terminal in a cell that does not transmit or actively transmit public information, improving the communication process within a network energy-saving cell.

[0276] After receiving the first information, the terminal may also send an uplink request signal to request to obtain public information.

[0277] Please refer to Figure 15, which shows a flow chart of a cell communication method provided by an embodiment of the present application, which can be applied to a terminal and an access network device of a first cell. Based on the embodiment shown in Figure 11 or Figure 12, after sending / receiving the first information, step 603 can also be included.

[0278] Step 603: The terminal sends an uplink request signal, or determines whether to send an uplink request signal, where the uplink request signal is used to request to obtain public information of the first cell.

[0279] Optionally, the terminal sends an uplink request signal when not receiving the SIB1 of the first cell; or determines whether to send an uplink request signal when not receiving the SIB1 of the first cell.

[0280] For example, the relevant implementation method of step 603 can refer to any embodiment shown in FIG. 2 to FIG. 10 .

[0281] Optionally, the above steps 601, 602, and 603 may be arbitrarily combined to form a new embodiment. Steps 601 and 602 may be combined to form a new embodiment. For example, the terminal feeds back the second information to the first cell and performs cell reselection.

[0282] Step 601 and step 603 are combined to form a new embodiment. For example, the terminal feeds back the second information to the first cell and sends an uplink request signal to request public information.

[0283] Steps 602 and 603 are combined to form a new embodiment. For example, the terminal sends an uplink request signal to request public information, and if the request fails, performs cell reselection. Alternatively, the terminal performs cell reselection, and if cell reselection fails, sends an uplink request signal to request public information.

[0284] Step 601, step 602, and step 603 are combined to form a new embodiment. For example, the terminal feeds back the second information to the first cell, performs cell reselection, and sends an uplink request signal to request public information.

[0285] In summary, the method provided in this embodiment allows the terminal to, after receiving the first information, send an uplink request signal to the network, requesting the first cell to send public information, thereby waking up the first cell to send public information (e.g., SIB1) and executing a communication process with the first cell based on the public information. This method provides a method for operating a terminal in a cell that does not send or does not actively send public information, improving the communication process within a network energy-saving cell.

[0286] Energy consumption has become a significant component of operators' operating costs. According to a GSMA report, mobile network energy costs account for approximately 23% of operators' total costs. Most of this energy consumption comes from radio access networks, particularly active antenna units (AAUs), while data centers and fiber optic transmission contribute only a smaller share.

[0287] There are two types of network power consumption:

[0288] - Dynamic part: such as consumption during data transmission / reception;

[0289] - Static part: such as the consumption required to maintain the operation of the wireless access device, even when there is no continuous data transmission / reception.

[0290] This research should not only evaluate potential network energy savings but also assess and balance the impact on network and user performance. For example, it should not significantly impact certain KPIs (Key Performance Indicators), such as spectrum efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, and initial access performance.

[0291] Possible research directions include:

[0292] 1. Study procedures and signaling method(s) to support on-demand SIB1 for UEs in idle / inactive mode, including: [RAN1 / 2 / 3]

[0293] Triggering method by uplink wake-up-signal using an existing signal / channel.

[0294] Wake-up-signal configuration provisioning to UE.

[0295] -Note: No modification of SSB will be discussed under this objective.

[0296] Information exchange between gNBs at least for the configuration of wake-up signal, if necessary.

[0297] Checkpoint for normative work in RAN#105.

[0298] This application aims to solve the problem of how a UE can operate in a SIB1-less cell. A SIB1-less cell is a cell that sends SSBs but does not send or actively send SIB1.

[0299] Exemplarily, the uplink request signal may be a UL WUS, the first cell may be an NES cell, and the public information may include SIB 1. An exemplary embodiment of applying the method provided by the present application is given below.

[0300] In an optional embodiment, a method for triggering and sending a UL WUS is provided.

[0301] 1. The UE determines whether the sending of an UL WUS message can be triggered and / or in which cell the UE sends the UL WUS message. Optionally, this includes at least one of the following:

[0302] a) The conditions for sending UL WUS are configured by the network, or predefined, or determined by the UE implementation.

[0303] b) In which cell the UL WUS is sent is predefined or indicated by the network.

[0304] c) The conditions for UL WUS transmission can be found in Table 1.

[0305] 2. The UE sends a UL WUS message to the network. Optionally, this includes at least one of the following:

[0306] a) When the UL WUS sending conditions are met, the UE sends a UL WUS message to the network.

[0307] b) UL WUS message, used by the UE to request the NES cell to send common information, where the common information includes at least SIB1.

[0308] c) The UL WUS message may be sent on the cell where the UE currently resides (such as the anchor cell of the NES cell), or on the anchor cell of the NES cell, or by the UE on the NES cell.

[0309] d) Optionally, if the UL WUS is sent to the currently resident or anchor cell (ie, non-NES cell), the current base station forwards the SIB1 requirement information to the NES cell, or notifies the NES cell to send the SIB1.

[0310] 3. Optionally, if the UL WUS fails to be sent, or the NES cell does not send SIB1, or the network (NES or other cell) does not indicate that the UL WUS is received successfully, or the UE considers that the UL WUS fails or the request is unsuccessful or the request is not responded to, the UE may perform a first behavior, which includes at least one of the following:

[0311] a) Perform the actions for entering RRC IDLE (such as any of the items described in 3GPP TS 38.331 5.3.11);

[0312] b) record or indicate the failure cause value as UL WUS sending failure or response failure;

[0313] c) Stop the T390 timer;

[0314] d) perform UAC actions (at least one of the actions specified in 3GPP TS 38.331 5.3.14.4);

[0315] e) performing at least one of the RRC connection reject actions;

[0316] f) The T300 timer is considered to have timed out (further, at least one of the actions of the T300 timer timeout is performed).

[0317] Extended solution: For SIB1-less NES cells (with SSB), the processing of downlink paging messages received / related to paging messages. In this case, how to monitor paging, obtain SIB1 or request SIB1 transmission, or how to respond to paging can be one of the following methods:

[0318] 1) Solution 1: The core network, or the base station of the anchor cell, or the base station of the cell where the UE is currently camped, notifies the NES cell to send SIB1. Furthermore, the UE monitors paging based on the received SIB1.

[0319] Solution 2: Use a specific paging configuration to monitor paging messages from cells with SSBs but no SIB1. Furthermore, the UE can request the SIB1 of the NES cell to respond to paging or access the cell. Alternatively, the UE can use specific PRACH (Physical Random Access Channel) / RACH resources to respond to paging or access the cell. Optionally, the specific paging configuration and / or (P)RACH resources are predefined.

[0320] 3) Solution 3: The UE monitors paging in the NES cell. The configuration of the paging monitoring is obtained through the last serving cell (the last serving cell), or from the anchor cell / UE's current cell. Optionally, it is obtained through RRC release (RRC release message) or system information. Furthermore, the UE may request SIB1 of the NES cell to respond to paging or access the cell, or the UE uses specific PRACH / RACH resources to respond to paging or access the cell. Optionally, the specific PRACH / RACH resources may be obtained through the last serving cell, or from the anchor cell / UE's current cell. Optionally, it is obtained through RRC release or system information.

[0321] Extended Implementation Example 1: See Table 2. Before the NES cell wakes up (i.e., before SIB1 is sent), the UE cannot camp on the NES or can only camp on the anchor cell or other cells. For example, the UE camps on the anchor cell or other cells before the NES cell wakes up. For example, the UE can camp on the NES cell after the NES cell wakes up.

[0322] Table 2

[0323] Extended Implementation Example 2: See Table 3. Before the NES cell wakes up (i.e., before SIB1 is sent), the UE resides on the NES cell; after the NES cell wakes up, the UE resides on the NES cell. For example, before the NES cell wakes up (i.e., before SIB1 is sent), the UE pre-resides on the NES cell, and then, based on the public information of the NES cell (e.g., at least one of the information included in SIB1), ultimately resides on the NES cell, or whether it ultimately resides on the NES cell. For another example, upon discovering or detecting the NES cell, the UE sends a wake-up request, and after the NES cell wakes up, the UE resides on the NES cell. For another example, after the NES cell wakes up, the UE resides on the NES cell.

[0324] Table 3

[0325] The above method provides the process of how to trigger and send the UL WUS message, and clarifies the UL WUS process.

[0326] In another optional embodiment, a method for processing SIB1 shutdown is provided.

[0327] Among them, after the NES cell switches to sending SIB1, or the cell is in the SIB1 sending state, but the cell wants to save energy, that is, turn off SIB1, or not send SIB1, or not actively send SIB1, the processing method in this case is given below.

[0328] Solution 1 (Compared to Solution 2, Solution 1 involves interaction between the NES cell and the UE, ensuring that the UE and the network know each other's next actions or demands and perform relevant processing or judgment):

[0329] 1. The NES cell indicates first information, where the first information is used to instruct the NES cell not to send SIB1, or the NES cell switches to not sending SIB1, or the NES cell switches to an inactive state.

[0330] a) Optionally, the first information is carried by system information, such as indicated by MIB (Master Information Block) or SIB1.

[0331] b) Optionally, the first information may further indicate the inactive or non-sending SIB1 time period (including at least one of the following: start time, end time, time period).

[0332] 2. The UE receives the first information and / or responds to the first information.

[0333] a) For example, the UE sends second information to the network, where the second information is used to indicate to the network that the UE wishes the network state not to change, or to send SIB1, or to continue sending SIB1, or not to enter inactive mode, or to postpone entering inactive mode (e.g., further indicating the time point / time period at which the UE wishes the network to enter inactive mode), or that a UE exists in the cell or resides in the cell. Optionally, before sending the second information, the UE may determine whether to send the second information.

[0334] b) For example, the UE reselects to another cell, or considers the NES cell to be unavailable / cannot reside / barred / cannot be selected / cannot be reselected (further, the NES cell is considered to be unavailable / cannot reside / barred / cannot be selected / cannot be reselected for 300 seconds or the specified time period).

[0335] c) For example, the UE sends a UL WUS message to request the sending of SIB1 (for specific implementation, please refer to the embodiment described above).

[0336] Option 2:

[0337] 1. The NES cell does not send SIB1, or switches to not sending SIB1.

[0338] 2. The UE sends a UL WUS message to request the transmission of SIB1. Alternatively, if the UE cannot receive SIB1, the UE sends a UL WUS message to request the transmission of SIB1 (for specific implementation, please refer to the above-mentioned embodiment).

[0339] The above method provides the behavior when the network does not want to send SIB1, which can ensure the performance of UE and network.
