[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] The present invention is based on and claims the priority of Chinese patent application with application number 202410009938.3 and application date January 2, 2024. The entire content of the Chinese patent application is hereby incorporated by reference into the present invention. Technical Field

[0003] The present application relates to the field of communication technologies, and in particular to a network access method, apparatus, terminal equipment, base station, and readable storage medium. Background Art

[0004] With the evolution of communication technology, networks will deploy different radio access technologies (RATs) simultaneously, such as the 4th Generation Mobile Communication Technology (4G) and the 5th Generation Mobile Communication Technology (5G). Similar to the 5G voice fallback mechanism, the functions supported by different RATs may vary or have different advantages and disadvantages. Therefore, fallback or redirection is required to allow user equipment (UE) to access cells of different standards to complete certain services.

[0005] In the Evolved Packet System (EPS) Fallback mechanism of 5G voice, the service request (Service Request) in the voice establishment process is sent in Message 5 (Msg5) when the UE enters the connected state (Connected). That is, in order to enable the UE to enter the connected state, the network side and the UE have performed necessary resource configuration and protocol stack establishment and other related processes. Redirection requires releasing the UE to the idle state (Idle) again, and the UE reselects to the appropriate cell based on the reselection priority information carried in the release (Release).

[0143] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0144] To make the embodiments of the present application clearer, the technical knowledge related to the embodiments of the present application is first introduced as follows:

[0145] 1. 5G Voice Solution

[0146] As the 4th Generation Mobile Communication Technology (4G) Long Term Evolution (LTE) enters the large-scale commercial stage, the future-oriented 5G has become a global research and development hotspot. There are many different voice solutions for 5G related to different networking modes. At present, the 3rd Generation Partnership Project (3GPP) has defined two solutions for 5G New Radio (NR) networking, namely Standalone (SA) and Non-Standalone (NSA). For the 5G non-standalone networking mode, since the control plane is anchored on the 4G network, it is a natural choice for voice services to use the LTE voice bearer (Voice over LTE, VoLTE) solution; for the 5G independent networking mode, 3GPP has proposed two solutions: Ultra High Definition Audio and Video Calls (Voice Over New Radio, VoNR) and EPS Fallback. Among them, the VoNR solution refers to the voice service based on the IP Multimedia Subsystem (IMS) provided by the 5G access network and core network, while the EPS Fallback solution refers to the terminal falling back to 4G when initiating an IMS call on 5G, and establishing VoLTE voice service through the 4G access network and core network. The fallback method can be switching.

[0147] 2. Terminal 5G call establishment process

[0148] The main processes include:

[0149] 1) After the terminal is powered on and a 5G cell is selected for residency, it first performs the power-on registration process (i.e., Registration). This is followed by the Protocol Data Unit (PDU) session establishment process, which establishes a Quality of Service (QoS) level 5 flow to carry Session Initiation Protocol (SIP) signaling. This process then initiates the IMS registration process. After completing IMS registration, the terminal enters the idle state.

[0150] 2) When the terminal initiates a call in idle state or receives a paging message as the called party, it first performs the Service Request process, re-establishes a QoS flow of level 5 to carry SIP signaling, and then sends a SIP signaling Invite to the IMS.

[0151] 3) After receiving the message, the IMS notifies the core network to prepare to establish a bearer. The core network then requires the base station to establish a QoS flow of level 1 to carry voice services. At this time, the VoNR and EPS Fallback schemes will be distinguished: if the base station selects the EPS Fallback scheme, it will refuse to establish the QoS flow for the voice service and execute the EPS Fallback process, that is, switching or redirecting the terminal to 4G. After that, the terminal completes the VoLTE call establishment on 4G; if the base station selects the VoNR scheme, it will send a Radio Resource Control (RRC) connection reconfiguration message to require the terminal to establish the QoS flow for the voice service until the VoNR voice establishment process is completed.

[0152] 3. Flexible community and network energy-saving technology

[0153] Current discussions on flexible cells and network energy-saving technologies involve the concepts of anchor cells and non-anchor cells. Generally speaking, anchor cells are mainly used to receive system messages and initiate random access channels (RACH), while non-anchor cells are mainly used for data reception.

[0154] From the above related technical introduction, we can see that due to the evolution of technology, the network will deploy different RAT technologies at the same time, such as 4G and 5G. Similarly, in the future, 5G may be deployed with other newer technologies, such as 6G (6 th Therefore, there is a mechanism similar to 5G voice fallback. The functions supported by different RATs may vary or have advantages and disadvantages. Therefore, it is necessary to use fallback or redirection to allow the UE to access cells of other standards to complete a certain service. From the EPS fallback mechanism for voice, the Service Request is sent in Msg5, that is, it is sent when the UE enters the connected state. It can be seen that both the network and the UE have made necessary resource configuration and protocol stack establishment for the UE to enter the connected state. Redirection requires releasing the UE to the Idle state again, and then the UE reselects the appropriate cell based on the reselection priority information carried in the Release.

[0155] It can be seen that the early operations of the UE and the network are useless. How to avoid useless operations on the network side and the UE side that bring power-consumption and achieve correct access of the UE is a problem existing in the existing technology and is also a problem that the solution of this application needs to solve.

[0156] In addition, similar to the above scenario, there are similar scenarios in flexible cell / network energy-saving technology. The UE may be configured with one anchor cell and one non-anchor cell. It is also necessary to solve which non-anchor cell the network activates and schedules to avoid useless scheduling and additional network power consumption, and to achieve correct UE access in this scenario.

[0157] The network access method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0158] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following description, but these technologies can also be applied to applications other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0160] Referring to FIG. 2 , FIG. 2 is a flowchart of a network access method provided in an embodiment of the present application, which is executed by a terminal device and includes the following steps:

[0161] Step 201: When the terminal device is about to access the network for the first time, first information is sent to the base station, where the first information is used to indicate access request related information.

[0162] The terminal device in the embodiment of the present application may refer to a UE, such as a mobile phone, a portable mobile terminal, etc. For the convenience of description, the embodiment of the present application is mainly explained using the UE as an example.

[0163] The base station in the embodiments of the present application may refer to a 5G, 6G, or other base station, without specific limitation. For example, the embodiments of the present application may be applicable to a UE initiating an access request to a 5G base station, with the 5G base station providing corresponding access resources for the UE, or providing the UE with 4G base station access resources for the UE to quickly access 4G, rather than rejecting the access request and requiring the UE to re-initiate the access process with the 4G base station.

[0164] In an embodiment of the present application, in order to avoid useless operations in the early stage of establishing a connection due to the base station selecting the EPS Fallback mechanism when the UE accesses the base station network, the signaling interaction process between the UE and the network side when accessing the network is improved and designed. In the scenario where the UE first accesses the network, the UE first reports relevant indication information to the base station. Specifically, the UE sends a first message to the base station, and the first information is used to indicate access request related information to inform the base station of the cell, frequency or service information that the UE wants to access, so that the base station can determine whether it can support the UE's access request based on the indication information, thereby determining the specific access resource related information to be fed back to the UE.

[0165] Optionally, the access request related information includes at least one of the following: the service requested by the terminal device, the frequency that the terminal device expects to access, and the cell that the terminal device expects to access.

[0166] That is, in some embodiments, the access request related information sent by the UE to the base station may include at least one of the service requested by the UE, the frequency that the UE expects to access, and the cell that the UE expects to access. That is, the UE can send relevant indication information to the pre-accessed base station to inform the base station of the service that the UE wants to receive, the cell and / or frequency that the UE expects to access, so that the base station can determine whether it can support the service requested by the UE, whether it is the cell that the UE expects to access, and / or whether the cell frequency is the frequency that the UE expects to access, etc., based on the indication information, thereby determining the specific information content to be fed back to the UE.

[0167] Step 202: Receive a first feedback message sent by the base station, wherein the first feedback message is determined based on the first information, and the first feedback message carries access resource related information.

[0168] The above-mentioned first feedback message is determined by the base station based on the first information sent by the UE. Specifically, the base station can determine whether it can support the UE's access request based on the information, such as whether it supports the service requested by the UE, whether it is the cell that the UE expects to access, and / or whether the cell frequency is the frequency that the UE expects to access, etc., thereby determining the access resource-related information that needs to be specifically carried in the feedback message to be sent to the UE.

[0169] Optionally, the access resource related information includes at least one of the following information: cell access resource information, first uplink scheduling resource information, and cell registration information.

[0170] In some specific embodiments, the base station may provide the UE with access resources of the current cell, i.e., the serving cell corresponding to the base station, upon determining that the base station can support the service requested by the UE, is the cell that the UE desires to access, and has the desired frequency. In this case, the base station may provide the UE with access resources of the current cell, i.e., the serving cell corresponding to the base station. In this case, the base station may provide the UE with feedback including access resource information of the current cell, so that the UE can quickly access the current cell according to the access resource information provided by the base station.

[0171] In any of the following situations, such as when the base station determines that it cannot support the service requested by the UE, is not the cell that the UE expects to access, or the cell frequency is not the frequency that the UE expects to access, the base station can provide the UE with other cell access resources that can support the service requested by the UE, or provide the UE with the cell access resources that the UE expects, or provide the UE with the cell access resources of the frequency that the UE expects. Of course, the base station can also provide the UE with the current cell access resources, or other accessible cell access resources, where the current cell is the service cell corresponding to the base station. That is, in this case, the base station can feedback a message including other relevant cell access resource information and / or access resource information of the current cell to the UE, so that the UE can quickly access other cells and / or the current cell according to the access resource information provided by the base station.

[0172] It should be noted that before the base station sends other cell access resource information to the UE, the UE may need additional uplink scheduling resources, such as uplink authorization (UL Grant), to receive the cell access resources fed back by the base station. At this time, the base station can first feed back a message including additional uplink scheduling resources to the UE, that is, the first feedback message carries the first uplink scheduling resource information. Subsequently, the UE can continue to listen to the next scheduling information from the base station based on the uplink scheduling resources, and obtain the access resource information of other cells fed back by the base station to the UE.

[0173] In one case, the base station can directly access the current cell for the UE, or interact with other cells to access other cells for the UE, that is, the base station can assist the UE to register for access to the current cell or other cells, and then send the registration information of the UE in the accessed cell to the UE. At this time, the first feedback message carries the cell registration information.

[0174] In this way, the terminal device reports relevant indication information to the base station when accessing the network for the first time, so that the base station can provide the terminal device with corresponding cell access resources according to the indication information, or assist in providing corresponding cell access resources, or provide access for the terminal device, thereby avoiding redirecting the terminal device to other cells for access after the RRC establishment is completed, that is, avoiding the useless early operations of establishing a connection between the UE and the network side in the related technology, and saving signaling interaction resources.

[0175] Optionally, the access resource related information includes cell access resource information, and the cell access resource information includes at least one of the access resource information of the first cell and the access resource information of the second cell, the first cell is the service cell corresponding to the base station, and the second cell is other cells outside the first cell.

[0176] In some embodiments, the access resource-related information includes cell access resource information, that is, after receiving the first information of the UE, the base station can provide the UE with cell access resource information, such as the access resource information of the first cell, that is, the current cell and / or the access resource information of the second cell, that is, other accessible cells. The specific cell access resource information carried can be determined by the base station based on the first information of the UE.

[0177] Furthermore, the method further comprises:

[0178] Performing network access based on the cell access resource information;

[0179] Alternatively, the access resource related information includes first uplink scheduling resource information, and the method further includes:

[0180] Sending a resource acquisition request to the base station based on the first uplink scheduling resource information;

[0181] receiving cell access resource information including access resource information of a second cell sent by the base station, where the second cell is a cell other than a serving cell corresponding to the base station;

[0182] Network access is performed based on the cell access resource information.

[0183] In some embodiments, after receiving the first feedback message, the UE may perform network access based on the access resource information of the specific cells carried in the first feedback message, that is, initiate registration with these cells to establish an RRC connection.

[0184] In other embodiments, the first feedback message carries first uplink scheduling resource information, and the first uplink scheduling resource information may refer to uplink resource information used for uplink scheduling, such as including an additional UL Grant, which is used for subsequent UL information transmission in the RACH, such as for the UE to send measurement results or other service requests, expected serving cell and / or frequency information, etc. That is, after receiving the first information from the UE, if the base station determines that the current cell cannot support the UE's service, or is not the cell and frequency expected by the UE, it may first provide the UE with uplink scheduling resource information, so that the UE can use the uplink scheduling resource information to continue related resource scheduling with the base station.

[0185] Specifically, the UE can use the uplink scheduling resource information provided by the base station to send an uplink message to the base station, such as a resource acquisition request. The base station responds to the UE's request and returns corresponding cell access resource information to the UE, such as feedback on access resource information of other accessible cells; the UE can then access the network based on the cell access resource information, that is, initiate registration with other cells to establish an RRC connection.

[0186] Through this implementation, the UE can quickly access the cell network, avoid excessive and useless signaling interactions between the UE and the network side, and avoid additional power consumption.

[0187] Optionally, the first information is carried in message (Message, MSG) 1, MSG3 or MSG5.

[0188] In some embodiments, when the UE sends the first information to the base station, the UE may specifically send the first information through a message such as MSG1, MSG3, or MSG5 during a random access process. That is, the first information may be carried in the MSG1, MSG3, or MSG5 message and sent to the base station. In this way, signaling overhead can be saved, and no additional signaling resources are required to send the indication information.

[0189] Optionally, the first information is indicated by a preamble code and / or a random access channel RACH resource preconfigured in MSG1;

[0190] Alternatively, the first information is indicated by a designated field in MSG3, where the designated field includes at least one of a designated logical channel identifier (LCID) and a designated bit or a bit sequence;

[0191] Alternatively, the first information is carried in the terminal capability information and / or the scheduling request (SR) in MSG5.

[0192] In some embodiments, when the first information is sent via the MSG1 message, it can be implicitly indicated via a preamble preconfigured in the MSG1. For example, different preamble symbols can be used to indicate different services, cell IDs, or cell frequencies. It can also be implicitly indicated via RACH resources, such as using different RACH resources to indicate different services, cell IDs, or cell frequencies. Alternatively, the preamble and RACH resources preconfigured in the MSG1 can be combined to perform implicit indication using different preamble and RACH resource combinations. In this way, implicit indication can be implemented via the MSG1 message, and the security of information exchange between the UE and the network can be improved to a certain extent.

[0193] In other embodiments, when the first information is sent via an MSG3 message, it can be specifically indicated via a specific field in the MSG3 message, such as a specific LCID, a specific bit, or a specific bit sequence. In this way, specific indication can be provided via the MSG3 message, and the base station can obtain UE indication information from the MSG3 message.

[0194] In some other embodiments, when the first information is sent via an MSG5 message, it may be specifically carried in the terminal capability information and / or SR of the MSG5 for indication, i.e., the terminal capability information and / or SR include the first information. In this way, specific indication can be provided via the MSG5 message, and the base station can obtain UE indication information from the MSG5 message.

[0195] Optionally, before step 201, the method further includes:

[0196] Sending second information to the base station, wherein the second information is used to instruct the base station to allocate uplink scheduling resources for the terminal device, and / or to instruct the terminal device to support access in multiple cells;

[0197] In a case where the second information is used to instruct the base station to allocate uplink scheduling resources to the terminal device, the method further includes:

[0198] receiving second uplink scheduling resource information sent by the base station, wherein the second uplink scheduling resource information includes at least one of scheduling information of MSG3 and uplink scheduling resources;

[0199] The step 201 includes:

[0200] The first information is sent to the base station based on the second uplink scheduling resource information.

[0201] In some embodiments, the UE may send second information to the base station before sending the first information to instruct the base station to allocate uplink scheduling resources for sending the first information. For example, the UE may first indicate to the base station that more UL Grants need to be allocated to send the first information; or it may indicate to the base station that the UE supports access to multiple cells (also called indicating dual registration). In this way, the base station may subsequently provide the UE with multiple cell access resources or access multiple cells for the UE.

[0202] If the second information instructs the base station to allocate uplink scheduling resources to the UE, the base station can send second uplink scheduling resource information to the UE based on the indication. Specifically, the base station can provide scheduling information of MSG3 or MSG5, and can also provide additional uplink scheduling resources, such as providing an additional UL Grant, for the UE to send the first information, that is, the UE can use the scheduling information of MSG3 and / or the additional UL Grant provided by the base station to send the first information, such as sending the desired service, cell and / or frequency information.

[0203] When the UE sends the second information to the base station, it may specifically be sent via a message such as MSG1 or MSG3 during a random access process. That is, the second information may be carried in an MSG1 or MSG3 message and sent to the base station. This saves signaling overhead and eliminates the need for additional signaling resources to send indication information. After receiving the first information, the base station allocates uplink scheduling resources to the UE. The UE may then send the first information to the base station based on the allocated uplink scheduling resources. Specifically, it may be sent via a message such as MSG3 or MSG5 during a random access process.

[0204] In this way, the UE can obtain uplink scheduling resources from the base station, and then send access-related indication information to the base station to achieve cell network access.

[0205] Optionally, before step 201, the method further includes:

[0206] receiving third information sent by the base station, wherein the third information includes service information supported by different cells or frequencies, and / or the third information is used to indicate that the base station supports collaborative work;

[0207] The step 201 includes:

[0208] Based on the third information, the first information is sent to the base station.

[0209] In some embodiments, the UE may send the first information based on the relevant indication information sent by the base station. Specifically, the base station may first send third information to the UE, and the third information may indicate the services supported by different cells or frequencies, so that the UE may determine the service, cell and / or frequency information specifically indicated in the first information based on the information and its own service usage requirements; the third information may also indicate that the base station supports collaborative work, that is, supports collaborative work with other base stations, and can interact with other base stations when necessary to obtain access resource information of other cells to provide to the UE or directly access other cells for the UE.

[0210] In this way, the UE can determine, based on the third information and the actual requested service, to which cell to send the first information, or determine the desired cell and / or frequency information specifically indicated in the first information, and then send the specific first information to the corresponding base station. In this embodiment, by initiating a corresponding access indication based on the relevant information provided by the base station, the efficiency and success rate of access can be improved.

[0211] It should be noted that the UE may also send the first information to the base station when it has a dual registration capability, such as supporting registration in two or more cells.

[0212] Optionally, the first information includes a service requested by the terminal device;

[0213] If the first cell supports the service, the first feedback message is sent through a random access response (RAR) or MSG4, and the access resource related information includes at least access resource information of the first cell, where the first cell is a serving cell corresponding to the base station;

[0214] When the first cell does not support the service, the first feedback message is sent through RAR, MSG4 or the first downlink message, and the access resource related information includes at least one of the access resource information of the second cell, the first uplink scheduling resource information and the cell registration information. The second cell is a cell other than the first cell, and the cell registration information is the registration information in the second cell.

[0215] In the embodiment of the present application, the base station may perform scheduling based on the first information of the UE. The scheduling here may include the following situations:

[0216] 1. The UE indicates service information, that is, the first information indicates the service requested by the UE

[0217] In this case, the base station will also have two different scheduling situations, specifically divided into two types: the current cell supports the service requested by the UE, and the current cell does not support the service. The specific scheduling methods are as follows:

[0218] If the current cell supports the service indicated by the UE, the base station can send a corresponding feedback message according to the existing mechanism, so that the UE can complete the random access process and receive the service data. The feedback message can be sent through messages such as RAR and MSG4. The access resource related information carried in the feedback message can include at least the access resource information of the current cell. The feedback message can also carry a scheduling message for scheduling UEMSG3 and MSG5, so that the UE completes RACH.

[0219] If the current cell does not support the service indicated by the UE, the base station may carry one or more of the following information in subsequent feedback messages, such as RAR, MSG4, or other new downlink messages: access resource information of other cells that support the service indicated by the UE, resource information used for the UE to send uplink scheduling information, and registration information of other cells that support the service indicated by the UE.

[0220] Through this implementation, when the UE indicates a service request, the base station can feed back corresponding information to the UE based on whether the service is supported, so that the UE can quickly access the cell network, or assist the UE in accessing an available cell network.

[0221] Optionally, when the first cell does not support the service, the access resource related information includes at least one of the following information:

[0222] Information about cells supporting the service;

[0223] Frequency information supporting the service;

[0224] Dedicated identification or neighboring cell access resources;

[0225] Scheduling information for uplink messages;

[0226] Uplink scheduling resources;

[0227] The first indication bit is used to instruct the terminal device to continue receiving uplink scheduling resources;

[0228] Access indication information, used to indicate whether the terminal device accesses the first cell and other cells;

[0229] Community registration information.

[0230] That is, in some embodiments, when the current cell does not support the UE-indicated service, the base station may carry one or more of the following information in the feedback message:

[0231] 1) Scheduling information of UE uplink messages, such as UL Grant, used to schedule UE MSG3 and MSG5, so that the UE can use the scheduling information to complete RACH;

[0232] 2) Other cells and / or frequency information that can support / access the services desired by the UE;

[0233] 3) Additional UL Grant, used for subsequent UL information transmission in RACH other than uplink messages (MSG3 or MSG5), such as measurement results, or for the UE to send other services and / or desired serving cell and / or frequency information;

[0234] 4) an indication bit, used to instruct the UE to continue receiving allocation of additional UL Grants. After receiving the indication, the UE will continue to listen, such as receiving the additional UL Grants described in 3);

[0235] 5) Dual registration indication information (also known as access indication information), used to indicate whether the UE completes RRC establishment in the current cell and completes RRC establishment in other cells;

[0236] 6) Dedicated UE identity (indicated as UE dedicated cell) or neighboring cell access resources, used for accessing the cell indicated by the base station;

[0237] 7) Cell registration information: For example, the current cell can trigger the UE to register in other RATs, that is, the UE registers in other cells, and the corresponding registration information can be sent to the UE, specifically through the current feedback message or through an additional downlink message.

[0238] The above information can better instruct the UE to complete cell network access, thereby improving access efficiency and success rate.

[0239] It should be noted that in some embodiments, the current cell may interact with other cells (such as those that can work in conjunction and / or indicate access to the UE), such as indicating UE information to other cells and / or obtaining identifiers and / or access resources available to UEs in other cells. This process may occur when the Xn interface is established and / or during UE random access.

[0240] Optionally, the first information includes a desired access frequency and / or a desired access cell;

[0241] The access resource related information includes at least one of the following:

[0242] Accessible cell information;

[0243] Accessible frequency information;

[0244] Scheduling information for uplink messages;

[0245] An indication of whether the cell desired to be accessed is activated;

[0246] Access indication information, used to indicate whether the terminal device accesses the first cell and other cells;

[0247] Community registration information.

[0248] In the embodiment of the present application, the scheduling performed by the base station based on the first information of the UE may also include the following second case:

[0249] 2. The UE indicates the frequency and / or cell that the UE expects to access. That is, the first information indicates the frequency and / or cell that the UE expects to access.

[0250] In this case, the base station may carry one or more of the following information in the feedback message:

[0251] 1) Scheduling information of UE uplink messages, such as UL Grant, used for scheduling UE MSG3 and MSG5;

[0252] 2) The UE expects an indication of whether the cell is activated, and possibly information related to its synchronization signal block (SSB) and / or access resources;

[0253] 3) Dual registration indication information (also known as access indication information), which is used to indicate whether the UE has completed RRC establishment in the current cell and in other cells;

[0254] 4) Information about accessible cells and / or frequencies; this information may be different from the desired cell / frequency information indicated by the UE;

[0255] 5) Cell registration information: For example, the current cell can trigger the UE to register in other RATs, that is, the UE registers in other cells, and the corresponding registration information can be sent to the UE, specifically through the current feedback message or through an additional downlink message.

[0256] The above information can better instruct the UE to complete cell network access, thereby improving access efficiency and success rate.

[0257] It should be noted that, in the embodiment of the present application, the scheduling performed by the base station based on the first information of the UE may also include the following third case:

[0258] 3. The UE indicates that an additional UL Grant is required for the transmission of the desired service and / or cell / frequency information

[0259] In this case, similar to the above, the base station may provide scheduling for MSG3, or additionally provide uplink scheduling for sending the UE's desired service and / or cell / frequency information.

[0260] Optionally, the performing network access based on the cell access resource information includes at least one of the following:

[0261] When the cell access resource information includes only the access resource information of the first cell, accessing the first cell based on the access resource information of the first cell;

[0262] When the cell access resource information includes only the access resource information of the second cell, terminating access to the first cell, and accessing the second cell based on the access resource information of the second cell;

[0263] In a case where the cell access resource information includes access resource information of the first cell and access resource information of the second cell, the first cell and the second cell are accessed based on the access resource information of the first cell and the access resource information of the second cell, respectively.

[0264] That is, in some embodiments, the UE may perform different access behaviors based on different base station feedback information. Specifically, based on the network feedback information, the UE's access behavior may be one or more of the following behaviors:

[0265] 1) If the base station feedback message indicates access to the current cell and / or access resources to the current cell are provided, the UE may continue to complete the RRC establishment in the current cell and then receive services;

[0266] 2) If the base station feedback message indicates access to other cells and / or access resources to other cells are provided, the UE may terminate the RACH process in the current cell based on the network indication information and reselect to the other cell indicated by the network for access and service data reception;

[0267] 3) When the base station feedback message carries uplink scheduling resource information, the UE can terminate the RACH process in the current cell, listen to the second scheduling information, obtain information about other cells, and reselect to other cells indicated by the network for access and service data reception;

[0268] 4) If the base station feedback message indicates that both the current cell and other cells are accessed, and / or access resources for the current cell and other cells are provided, the UE may continue the RRC establishment of the current cell and establish RRC in other cells indicated by the network (the network indication information may be directly carried in MSG2 or MSG4 or in other messages), retaining two RRCs, i.e., accessing two cells, and receiving service data in the cell indicated by the network;

[0269] 5) When the base station feedback message carries uplink scheduling resource information, the UE may also perform measurement according to the measurement target configured by the base station and send the measurement results and / or the current access cell and frequency information.

[0270] In this way, the UE can perform corresponding access behaviors according to different feedback / scheduling information of the network, and can complete network access with fewer signaling interaction processes.

[0271] It should be noted that when the above-mentioned UE accesses the current cell and other cells at the same time, it is convenient for the UE to receive other services in the future without having to access the current cell again, and it can also avoid the uselessness of the previous interaction process; and when the above-mentioned UE is only connected to one cell, the UE behavior can be simpler, and the network side does not need to perform resource configuration and scheduling with the UE.

[0272] Optionally, the cell access resource information includes only access resource information of the second cell;

[0273] The performing network access based on the cell access resource information includes:

[0274] An access request is initiated to the second cell, wherein the access request carries fourth information, and the fourth information is used to indicate that the access request is initiated based on an indication of a cell other than the second cell.

[0275] In other words, in some embodiments, if a UE accesses another cell to receive service data, a relevant indication can be included during the access process to indicate whether the access is being directed by a cell other than the currently accessed cell. For example, when initiating an access request to a second cell, the request can indicate that the access is being made based on the indication from the first cell. In this way, the cell requesting access can respond to the UE's access request first, thereby increasing the probability of successful access.

[0276] The embodiments of the present application indicate the network's desired service, cell, and frequency information upon initial network access, allowing the base station to provide corresponding access resources or assist in providing access resources to other cells based on the UE's instructions, without requiring the UE to fall back to other cells and re-initiate the access process. Compared to existing redirection or cell reselection methods, this can significantly save interactive signaling. In other words, the embodiments of the present application can avoid redirecting the UE to other cells to access and then receive certain service data after RRC establishment is complete, thereby avoiding additional power consumption and signaling interaction between the UE and the network.

[0277] In the network access method of an embodiment of the present application, when a terminal device is about to access the network for the first time, the terminal device sends a first message to the base station, where the first message is used to indicate information related to the access request; and receives a first feedback message sent by the base station, where the first feedback message is determined based on the first information and carries information related to access resources. In this way, the terminal device reports relevant indication information to the base station when accessing the network for the first time, so that the base station can provide the terminal device with corresponding information related to access resources according to the indication information, thereby avoiding redirecting the terminal device to other cells for access after the RRC establishment is completed, that is, avoiding the useless early operations of establishing a connection between the UE and the network side in the related technology, and saving signaling interaction resources.

[0303] Based on the second information, second uplink scheduling resource information is sent to the terminal device, wherein the second uplink scheduling resource information includes at least one of the scheduling information of MSG3 and the uplink scheduling resource;

[0304] The step 301 includes:
