[0050] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as User Equipment (UE), and can be a mobile phone, tablet computer, laptop computer, notebook computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among these, in-vehicle devices can also be referred to as in-vehicle terminals, in-vehicle controllers, in-vehicle modules, in-vehicle components, in-vehicle chips, or in-vehicle units, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment. Network-side equipment 12 may include access network equipment or core network equipment, wherein access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit. Access network equipment may include base stations, Wireless Local Area Network (WLAN) access points (APs), or Wireless Fidelity (WiFi) nodes, etc.Among them, base stations can be referred to as Node B (NB), Evolved Node B (eNB), Next Generation Node B (gNB), New Radio Node B (NR Node B), Access Point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B, Transmit / Receive Point (TRP), Non-Terrestrial Network (NTN) equipment (such as satellite or high altitude platform stations). The term "base station" can be any suitable term in the field, such as "station" or any other appropriate term in the relevant field, as long as the same technical effect is achieved. The term "base station" is not limited to specific technical terms. It should be noted that the embodiments of this application only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0051] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), and Binding Support. Functions include BSF, Application Function (AF), Location Management Function (LMF), Gateway Mobile Location Centre (GMLC), Network Data Analytics Function (NWDAF), and Non-Terrestrial Network (NTN) devices (such as satellite or high altitude platform stations).It should be noted that the embodiments of this application only use the core network equipment in the NR system as an example for introduction, and do not limit the specific type of core network equipment. If the name of the core network equipment mentioned in the embodiments of this application changes in subsequent protocol versions (e.g., 6G), it is also within the scope of protection of this application.

[0052] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0053] NTN communication systems include two types: transparent payload-based NTN communication systems and regenerative payload-based NTN communication systems. In 3GPP Releases 17 and 18, only transparent payload-based NTN communication systems were considered. In this deployment environment, terminals, base stations, and core network equipment are all deployed on the ground, and communication data between terminals and network-side equipment is relayed via satellite. In this system, the satellite is only used to relay data between the base station and the terminal; it does not decode or process this data. In 3GPP Release 19, the system was extended to regenerative payload-based NTN systems. In this deployment environment, the satellite has all the functions of a base station and can decode and process uplink or downlink data.

[0054] Based on satellite orbital altitude, NTN communication systems are divided into high-Earth orbit (GEO), low-Earth orbit (LEO), and medium-Earth orbit (MEO) satellite communication systems. GEO satellites are commonly found in geostationary orbits (GEO), with an altitude of 35,786 km, and are stationary relative to the Earth's surface. Low-Earth orbit (LEO) satellites typically have an altitude range of 600 km to 1200 km. Medium-Earth orbit (MEO) satellites typically have an altitude range of 2000 km to 10000 km.

[0055] Narrow Band (NB) Internet of Things (IoT) is a low-power wide-area network technology standard used to connect various smart sensors and devices using wireless cellular networks, providing long-range, wide-coverage, and highly reliable communication services. NB-IoT is developed on the LTE standard and can be understood as a simplified version of LTE. Compared to LTE, NB-IoT UEs do not support the following processes: connected-mode mobility management (e.g., handover and measurement reporting), inter-RAT cell reselection, inter-RAT mobility in connected mode, Radio Resource Control (RRC) inactive mode (RRC_INACTIVE), carrier aggregation (CA), dual connectivity (DC), etc.

[0056] For NB-IoT, multi-carrier operation is supported. The system can simultaneously provide multiple carrier services within a cell, namely one anchor carrier and one or more non-anchor carriers. On the anchor carrier, the terminal receives primary synchronization signals, secondary synchronization information, system messages, paging messages, or performs random access procedures. For connected terminals, the network can configure non-anchor carriers for unicast service transmission via dedicated signaling. If the terminal is not configured with a non-anchor carrier, all transmissions are performed on the anchor carrier. For idle terminals, system messages (such as SIB22 / 23-NB, i.e., SIB22 / 23 in the NB-IoT system) can instruct the terminal to receive paging messages or perform random access on non-anchor carriers. The base station can configure the selection probability of random access resources on anchor and non-anchor carriers via system messages. The terminal selects random access resources on the carrier according to the access probability to perform random access procedures. The base station can configure the paging probability on anchor and non-anchor carriers via system messages (such as SIB22 / 23-NB). The terminal determines the paging carrier based on the paging probability to receive paging from the network.

[0057] High-orbit satellite communication boasts advantages such as wide coverage and high industry maturity, holding immense potential for voice communication in remote environments like oceans and deserts. Currently, 3GPP is researching support for narrowband voice via high-orbit satellites, enabling users to directly connect their mobile phones to these satellites for real-time voice communication, significantly expanding the boundaries of communication services. However, communication capacity is limited in high-orbit scenarios, and preventing unnecessary network access attempts by terminals is a problem that needs to be addressed. In particular, when supporting voice services via high-orbit satellites, the significant communication resources required (e.g., voice calls are bidirectional and can last for extended periods, necessitating substantial uplink and downlink communication resources) can easily limit or exhaust communication capacity, preventing the acceptance of more terminals. Therefore, preventing unnecessary network access attempts by terminals in this scenario is a critical issue. Furthermore, when communication capacity is no longer limited or resources are sufficient, ensuring timely network access for terminals remains a challenge. Additionally, in multi-carrier operation scenarios, while existing mechanisms allow base stations to instruct terminals to select other carriers for random access, the carrier selection probability information is currently provided through system messages. The process of obtaining these messages introduces a delay, preventing terminals from quickly accessing the network. To address these issues, this application proposes an access processing method.

[0058] The access processing method, apparatus, terminal, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0059] Please refer to Figure 2, which is a flowchart of one of the access processing methods provided in an embodiment of this application. The method is executed by a terminal. As shown in Figure 2, the method includes the following steps:

[0060] Step 201: The terminal receives the first information sent by the network-side device.

[0061] The first information includes one or more of the following: access control information and carrier selection information.

[0062] It should be noted that the terminal can be an NB-IoT terminal, and the network-side device can be an NB-IoT network-side device.

[0063] It should be noted that the access control information can be understood as information related to the terminal's access operation. For example, the access control information can indicate that access is prohibited or access is allowed (or can be understood as access not being prohibited), so that the terminal can know whether it can perform the access operation based on the access control information.

[0064] The carrier selection information can be understood as information related to the carrier selection of the terminal. For example, the carrier selection information can indicate whether the anchor carrier is allowed to be selected or prohibited from being selected, or it can also indicate whether the non-anchor carrier is allowed to be selected or prohibited from being selected. Thus, based on the carrier selection information, the terminal can determine whether it can select an anchor carrier or a non-anchor carrier to perform random access.

[0065] Optionally, the first information may be carried via any of the following messages:

[0066] Paging messages;

[0067] Random access response message;

[0068] Connection establishment rejected message;

[0069] Connection reconstruction refused message.

[0070] As an example, when the first information is carried via a paging message, on the one hand, the network-side device can provide the first information to the terminal more dynamically to assist the terminal in performing the operation of accessing the network-side device, and can adapt to changes in network capacity more quickly. On the other hand, compared to obtaining access control-related information (such as access denied or allowed, or carrier selection information) from system messages, obtaining it via paging messages is faster and reduces information reception latency.

[0071] As another example, by carrying the first information in the random access response message, the terminal can obtain the first information in a timely manner during the random access process, enabling the terminal to perform the operation of accessing the network-side device. For instance, if the network capacity is limited or unable to accommodate more users when the terminal performs a random access process to access the network-side device, the network can inform the terminal that access is prohibited through the random access response message, and the terminal will not continue to attempt random access. Alternatively, the network can inform the terminal of the allowed access time information through the random access response message, and the terminal will subsequently attempt random access again within the allowed access time.

[0072] As another example, when the connection establishment rejection message carries the first information, the terminal can obtain the first information in a timely manner during the connection establishment process, enabling the terminal to perform the operation of accessing the network-side device. For instance, if the network capacity is limited or unable to accommodate more users when the terminal performs the connection establishment process to access the network-side device, the network can inform the terminal that access is prohibited through the connection establishment rejection message, and the terminal will no longer attempt to perform the connection establishment process. Alternatively, the network can inform the terminal of the allowed access time information through the connection establishment rejection message, and the terminal will subsequently attempt to perform the connection establishment process again within the allowed access time.

[0073] As another example, when the connection reconstruction rejection message carries the first information, the terminal can obtain the first information in a timely manner during the connection reconstruction process, enabling the terminal to perform the operation of accessing the network-side device. For instance, if the network capacity is limited or unable to accommodate more users when the terminal performs the connection reconstruction process to access the network-side device, the network can inform the terminal that access is prohibited through the connection reconstruction rejection message, and the terminal will no longer attempt to perform the connection reconstruction process. Alternatively, the network can inform the terminal of the allowed access time information through the connection reconstruction rejection message, and the terminal will subsequently attempt to perform the connection reconstruction process again within the allowed access time.

[0074] In this embodiment, the network-side device can carry the first information through any of the above messages, such as carrying the first information in the paging message or in the random access response message. This makes the method of sending the first information more flexible.

[0075] Optionally, the terminal has a first capability, which is the ability of the terminal to receive the first information.

[0076] For example, if the first information is carried via a paging message, then the terminal has the capability to receive the first information via a paging message.

[0077] Optionally, the paging message includes a first indication field, which carries the access control information. Exemplarily, a new information field (e.g., the first indication field) can be introduced into an existing paging message to carry the access control information. As an embodiment, the ability to receive the first information via the paging message can be a signaling-free reporting capability, thereby helping to save terminal power consumption.

[0078] It is understood that when the first information is carried through other messages (e.g., random access response message, connection establishment rejection message, or connection reconstruction rejection message), the terminal has the capability to receive the first message through other messages. Optionally, the terminal can indicate to the network-side device that it possesses the first capability. As one embodiment, when the terminal has the capability to receive the first information from a random access response message, the terminal indicates to the network-side device that it possesses the first capability during the random access process. For example, the terminal can initiate a random access process using dedicated random access resources (such as preambles), and the network-side device implicitly determines that the terminal possesses the first capability based on these dedicated random access resources. As another embodiment, when the terminal has the capability to receive the first information from a connection establishment rejection message, the terminal indicates to the network-side device that it possesses the first capability during the connection establishment process. For example, the terminal can map a connection establishment request message to a dedicated logical channel, and the network-side device implicitly determines that the terminal possesses the first capability based on these dedicated logical channels. As another embodiment, when the terminal has the capability to receive the first information from a connection reconstruction rejection message, the terminal indicates to the network-side device that it possesses the first capability during the connection reconstruction process. For example, the terminal can map the connection reconstruction request message to a dedicated logical channel, and the network-side device can implicitly determine that the terminal has the first capability based on the dedicated logical channel.

[0079] Furthermore, in some embodiments, the prerequisite capability or precondition for receiving the first message may be that the terminal has the capability to support voice functionality. For example, the prerequisite capability or precondition for receiving the first message via a paging message may be that the terminal has the capability to support voice functionality. It is understood that for a terminal supporting voice functionality, the terminal further possesses the capability to receive the first message via a paging message.

[0080] Furthermore, in some embodiments, the ability to receive the first message may be that the terminal has the ability to support voice functionality. In this embodiment, when the terminal supports voice functionality, the terminal also has the ability to receive the first information via a paging message.

[0081] In this embodiment of the application, the method further includes:

[0082] The terminal's access layer (AS) receives the first information;

[0083] The terminal's AS forwards the first information to the terminal's Non-Access Stratum (NAS).

[0084] For example, the terminal's AS receives the first information sent by the network-side device, and further forwards the first information to the terminal's NAS through the AS.

[0085] It should be noted that the AS layer of the terminal can directly forward the received first information to the NAS layer of the terminal. Alternatively, the AS layer of the terminal can indirectly forward the received first information to the NAS layer of the terminal. It is understood that the AS layer of the terminal can convert the information contained in the first information into other information forms before forwarding it to the NAS layer of the terminal.

[0086] Optionally, based on the first information forwarded by the AS layer of the terminal, the NAS layer of the terminal determines whether to trigger a connection establishment process. For example, when an uplink service arrives, if the first information indicates that cell access is prohibited, the NAS layer of the terminal does not trigger the underlying layer (such as the RRC layer) to initiate an RRC connection establishment process. For example, when a voice service needs to be initiated, if the first information indicates that voice service access is prohibited, the NAS layer of the terminal does not trigger the underlying layer (such as the RRC layer) to initiate an RRC connection establishment process.

[0087] Step 202: Based on the first information, the terminal performs operations related to accessing the network-side device.

[0088] For example, in some embodiments, the first information includes access control information. For instance, if the access control information indicates that access is allowed, the terminal accesses the network-side device based on the access control information; or if the access control information indicates that access is prohibited, the terminal does not access the network-side device based on the access control information, or the terminal accesses the network-side device after a preset interval, thereby avoiding unnecessary access attempts by the terminal and helping to save terminal power consumption. It should be noted that the access control information may also include other content, and the terminal performing operations related to accessing the network-side device based on the access control information may also be in other possible situations, which will not be elaborated here.

[0089] In some embodiments, the first information includes carrier selection information. For example, if the carrier selection information includes anchor carrier selection information, the terminal selects an anchor carrier to perform random access based on the carrier selection information. Alternatively, if the carrier selection information includes non-anchor carrier selection information, the terminal selects a non-anchor carrier to perform random access based on the carrier selection information. It should be noted that the carrier selection information may also include other content, and the terminal's operation related to accessing the network-side device based on the carrier selection information may also involve other possibilities, which will not be elaborated here.

[0090] In some embodiments, the first information includes carrier selection information and access control information. For example, the carrier selection information includes anchor carrier selection information, and the access control information indicates that access is allowed, in which case the terminal selects an anchor carrier to perform random access. Alternatively, if the carrier selection information includes anchor carrier selection information and the access control information indicates that access is prohibited, the terminal will not perform any operations related to accessing the network-side device, thereby avoiding unnecessary access attempts by the terminal. It is understood that the carrier selection information and the access control information may also include other content, and the terminal performing operations related to accessing the network-side device based on the carrier selection information may also be in other possible situations, which will not be specifically elaborated here.

[0091] In this embodiment, the terminal receives first information sent by a network-side device. This first information includes at least one of access control information and carrier selection information. Based on this first information, the terminal performs operations related to accessing the network-side device, such as accessing or not accessing the network-side device. Thus, the terminal can determine whether it can access the network-side device based on the first information, avoiding unnecessary access attempts and helping to save terminal power. Furthermore, since the first information includes carrier selection information, the terminal can perform carrier selection based on this information, such as anchor carriers or non-anchor carriers, and perform random access, thereby facilitating rapid access to the network-side device and improving the terminal's communication efficiency.

[0092] Optionally, the access control information includes one or more of the following:

[0093] System capacity indication information; wherein, the system capacity indication information is used to indicate whether the system capacity is limited or unlimited.

[0094] Access indication information; wherein, the access indication information is used to indicate that access is prohibited or access is permitted;

[0095] Access time information; wherein, the access time information is used to indicate the time information during which access is prohibited or allowed.

[0096] Optionally, the system capacity indication information includes any one of the following:

[0097] System capacity limited indication information, which is used to indicate that the system capacity is limited;

[0098] The system capacity is not limited indication information, which is used to indicate that the system capacity is not limited.

[0099] It should be noted that the aforementioned "limited system capacity" can be understood as the system's communication resources being exhausted, about to be exhausted, or insufficient, or as the network-side equipment being unable to accept terminal access or about to be unable to accept terminal access. Conversely, the aforementioned "unlimited system capacity" can be understood as the system's communication resources being surplus or sufficient, or as the network-side equipment still being able to accept terminal access.

[0100] For example, the system capacity indication information can be a 1-bit indication. For instance, when this information field exists or is set to "1", it indicates that the system capacity is limited; when the information field does not exist or is set to "0", it indicates that the system capacity is not limited. As another embodiment, the system capacity indication information can be a percentage value. For example, a percentage value of 100% indicates that the system capacity is exhausted, limited, or about to be exhausted, which can be understood as the network no longer accepting new terminal access. For example, a percentage value of 10% indicates that the system capacity is not limited or has surplus capacity, which can be understood as the network still accepting new terminal access. It should be noted that a specific ratio can be agreed upon or negotiated to represent whether the system capacity is limited. For example, it can be agreed that if the system capacity ratio is less than or equal to 80%, the system capacity is not limited. Or it can be agreed that if the system capacity ratio is greater than or equal to 80%, the system capacity is limited. For instance, when a terminal receives system capacity indication information (e.g., 90%, i.e., >80%) sent by a network-side device, the terminal can know that the system capacity is limited, and the terminal will be prohibited from accessing the network-side device. When the terminal receives system capacity indication information again (e.g., 40%, i.e., <80%), the terminal can know that the system capacity is not limited, and the terminal can access the network-side device.

[0101] It should be noted that when system capacity is limited, meaning the network-side device can no longer accept terminal access, the limited system capacity information indicates that terminal access is prohibited. Based on this information, the terminal will not attempt to access the network-side device, thus avoiding unnecessary access attempts and helping to save terminal power. Conversely, when system capacity is unlimited, meaning the network-side device allows terminal access, the terminal will attempt to access the network-side device based on this information, enabling rapid access based on system capacity.

[0102] In this embodiment of the application, the access control information may further include access indication information, which is used to indicate whether access is prohibited or allowed, so that the terminal can determine whether it can access the network-side device based on the access indication information.

[0103] Optionally, the access indication information includes one or more of the following:

[0104] Community access indication information;

[0105] Carrier access indication information;

[0106] Service access instruction information.

[0107] The cell access indication information is used to indicate whether cell access is prohibited or allowed. For example, the cell access indication information can be a 1-bit indication; for instance, when the indication is set to "barred," it indicates that cell access is prohibited, and the terminal will not access the cell corresponding to that indication; when the indication is set to "not barred," it indicates that cell access is allowed, and the terminal can access the cell corresponding to that indication.

[0108] The carrier access indication information is used to indicate whether carrier access is prohibited or permitted. In some embodiments, the carrier access indication information may be a bitmap, where each bit corresponds to a carrier, and the value of the bit indicates whether the corresponding carrier access is prohibited or permitted. For example, when the value of a bit is "1", it indicates that the carrier access corresponding to that bit is prohibited, and when the value of a bit is "0", it indicates that the carrier access corresponding to that bit is permitted.

[0109] In other embodiments, the carrier access indication information may be a list, where each element of the list corresponds to a carrier, and the element is used to indicate whether access to the corresponding carrier is prohibited or permitted.

[0110] The carrier indicated by the carrier indication information may be an anchor carrier and / or a non-anchor carrier, and the carrier indication information includes anchor carrier indication information and / or non-anchor carrier indication information.

[0111] The service access indication information is used to indicate whether service access is prohibited or permitted. The service can be a calling service or an emergency service, etc. It should be noted that, when the service access indication information indicates that service access is prohibited, the service access indication information also includes a service disabling factor, which indicates the reason for the prohibition of service access.

[0112] In this embodiment, the access control information further includes access time information, which indicates the time during which access is prohibited and / or the time during which access is permitted. Therefore, based on the access time information, the terminal can determine when it can access the network-side device. For example, if the access time information indicates a time during which access is prohibited, the terminal can choose not to access the network during that prohibited time and can access the network outside of that prohibited time. This avoids unnecessary access attempts by the terminal and allows the terminal to access the network promptly outside of the prohibited time.

[0113] Optionally, the access time information includes one or more of the following:

[0114] Access time information for the community;

[0115] Carrier access time information;

[0116] Information on the service access time.

[0117] For example, the access time information includes cell access time information, which indicates the times when access is prohibited and / or permitted in the cell. Based on the cell access time information, the terminal can determine when it can access the cell, avoiding unnecessary access attempts and thus saving terminal power consumption.

[0118] For example, the access time information includes carrier access time information, which is used to indicate the time when access is prohibited and / or the time when access is permitted. Based on the carrier access time information, the terminal can determine when to select a carrier for random access and which carrier to select for random access.

[0119] For example, the access time information includes service access time information, which indicates the times when service access is prohibited and / or the times when access is permitted. Based on the service access time information, the terminal can clearly determine which services are prohibited from accessing at which times and which services are permitted from accessing at which times.

[0120] In this embodiment of the application, when the first information includes access control information, the step of the terminal performing operations related to accessing the network-side device based on the first information includes one or more of the following:

[0121] When the access control information indicates that the system capacity is limited, the terminal is prohibited from accessing the network-side device;

[0122] When the access control information indicates that the system capacity is not limited, the terminal accesses the network-side device;

[0123] When the access control information indicates that access to the first cell is prohibited, the terminal is prohibited from accessing the network-side device through the first cell; for example, the terminal can access the network-side device through a second cell, in which case access to the second cell is allowed.

[0124] When the access control information indicates that access to the first cell is permitted, the terminal accesses the network-side equipment through the first cell;

[0125] When the access control information indicates that access to the first carrier is prohibited, the terminal is prohibited from accessing the network-side device via the first carrier; for example, the terminal can choose to access the network-side device via a second carrier, in which case access to the second carrier is allowed.

[0126] When the access control information indicates that access to the first carrier is permitted, the terminal accesses the network-side device via the first carrier;

[0127] When the access control information indicates that access to the first service is permitted, the terminal accesses the network-side device to obtain the first service.

[0128] When the access control information indicates that access to the first service is prohibited, the terminal is prohibited from accessing the network-side device to obtain the first service.

[0129] When the access control information indicates a time period for allowing access, the terminal accesses the network-side device within the time period indicated by the time period for allowing access.

[0130] When the access control information indicates a time when access is prohibited, the terminal is prohibited from accessing the network-side device during the time indicated by the access prohibition time information. For example, the terminal can choose to access the network-side device outside the time indicated by the access prohibition time information.

[0131] It should be noted that the terminal can perform any one or more of the above operations. As an example, when the access control information indicates that cell access is allowed and first service access is prohibited, the terminal is prohibited from accessing the network-side device to obtain the first service. However, the terminal can access the network-side device to obtain the second service. For example, if the network-side device has insufficient communication resources, and voice services require significant communication resources, the network-side device may indicate that voice services are prohibited, but allow other services (such as SMS services) to access. In this case, the terminal will not initiate voice services on the network-side device. However, the terminal can initiate other services, such as SMS services, on the network-side device.

[0132] In this embodiment, the terminal can perform operations such as accessing the network-side device, not accessing the network-side device, or delaying access to the network-side device according to the content indicated by the access indication information. This helps the terminal avoid unnecessary access attempts and can also effectively improve the terminal's access efficiency.

[0133] In this embodiment of the application, the first information may further include carrier selection information, which is used to assist the terminal in accessing the network-side device.

[0134] Optionally, the carrier selection information includes one or more of the following:

[0135] Anchor carrier selection information;

[0136] Selection information for random access resources on the anchor carrier;

[0137] Selection information for non-anchor carriers;

[0138] Selection information for random access resources on non-anchor carriers.

[0139] It should be noted that the selection information mentioned above can be selection probability information. For example, the selection probability information of the target object (anchor carrier, non-anchor carrier, random access resource on anchor carrier or random access resource on non-anchor carrier) is used to indicate the probability of the target object being selected, such as a selection probability of 0, 1 / 6, 1 / 8, 1 / 2, etc.

[0140] Alternatively, the aforementioned selection information can be availability information. For example, availability information for the target object (anchor carrier, non-anchor carrier, random access resources on an anchor carrier, or random access resources on a non-anchor carrier) indicates that the target object can be selected. Alternatively, the aforementioned selection information can be disallowed information. For example, disallowed information for the target object (anchor carrier, non-anchor carrier, random access resources on an anchor carrier, or random access resources on a non-anchor carrier) indicates that the target object cannot be selected. It should be noted that the aforementioned availability or disallowed information can be 1-bit indication information. For example, when the indication information is set to "true," "setup," or "1," it indicates availability information; when it is set to "false," "release," or "0," it indicates disallowed information.

[0141] For example, when the capacity of the anchor carrier is limited, the anchor carrier selection information can be used to indicate that the selection probability or access probability of the anchor carrier is 0 or that the anchor carrier access is prohibited. Based on the anchor carrier selection information, the terminal can then know that it cannot select the anchor carrier for access.

[0142] The selection information of the random access resource on the anchor carrier can be used to indicate the probability that the random access resource on the anchor carrier is selected. For example, the selection information of the random access resource on the anchor carrier can be represented by a list, where each item in the list corresponds to a random access resource on the anchor carrier, indicating the selection probability of the random access resource, or the probability that the terminal uses the random access resource to access the network.

[0143] The selection information for the non-anchor carrier can be used to indicate the probability of a non-anchor carrier being selected. For example, the selection information for the non-anchor carrier can be a list, where each item in the list corresponds to a non-anchor carrier and indicates the probability of that non-anchor carrier being selected. For instance, when the capacity of the non-anchor carrier is limited, the probability of the non-anchor carrier being selected or the access probability is 0, or access to the non-anchor carrier is prohibited, thereby preventing the terminal from accessing the non-anchor carrier.

[0144] The selection information of random access resources on the non-anchor carrier can be used to indicate the probability of a random access resource being selected on the non-anchor carrier. For example, the selection information of random access resources on the non-anchor carrier can be represented by a list, where each item in the list corresponds to a random access resource on the non-anchor carrier, indicating the selection probability of that random access resource, or the probability that the terminal will use that random access resource to access the network.

[0145] Optionally, in some embodiments, the network can simultaneously indicate selection information for multiple carriers. For example, when carrier 1 has limited capacity, the network-side device can indicate that carrier 1 is prohibited from access, unavailable, or has a selection probability of 0. The network-side device can also indicate that carrier 2 is allowed to access, available, or has a selection probability of 1. In this case, the terminal can select carrier 2 to initiate a random access procedure to access the network-side device.

[0146] It should be noted that when the carrier selection information includes anchor carrier selection information, the carrier selection information may not include non-anchor carrier selection information. In this case, the non-anchor carrier selection information is obtained based on the anchor carrier selection information. For example, the selection probability of a non-anchor carrier = 1 - the selection probability of an anchor carrier. For instance, if the anchor carrier selection probability is 0, then the selection probability of a non-anchor carrier = 1 - the anchor carrier selection probability, which is 1. Further, if there are multiple non-anchor carriers, the selection probability of a certain non-anchor carrier is (1 - the anchor carrier selection probability) / the number of non-anchor carriers. As another embodiment, if multiple non-anchor carriers have random access resources, the non-anchor carrier selection probability = (1 - the anchor carrier selection probability) / the number of random access resources on the non-anchor carrier. For example, if the anchor carrier selection probability is 0 and the number of non-anchor carriers with random resources is 4, then the selection probability of that non-anchor carrier is 1 / 4. Similarly, when the carrier selection information includes non-anchor carrier selection information, the carrier selection information may not include anchor carrier selection information. In this case, the anchor carrier selection information can be obtained based on the non-anchor carrier selection information.

[0147] Optionally, the carrier selection information may further include one or more of the following:

[0148] Carrier selection indication information; wherein, the carrier selection information is used to indicate whether a carrier is allowed to be selected or not, and the carrier may be an anchor carrier or a non-anchor carrier;

[0149] Carrier selection probability information; wherein, carrier selection probability information is used to indicate the probability of a carrier being selected;

[0150] Selection indication information for random resources on a carrier; wherein, the selection indication information for random access resources on a carrier is used to indicate whether random access resources on the carrier are allowed to be selected or prohibited from being selected;

[0151] Selection probability information of random resources on a carrier; wherein, the selection probability information of random resources on a carrier is used to indicate the probability of random access resources on a carrier being selected.

[0152] For example, the carrier selection information includes carrier selection indication information, which indicates that the anchor carrier is allowed to be selected, so the terminal can select the anchor carrier to perform random access; or, the carrier selection indication information indicates that the anchor carrier is prohibited from being selected, so the terminal can select a non-anchor carrier to perform random access.

[0153] For example, the carrier selection information includes carrier selection indication information and random access resource selection indication information on the carrier. The carrier selection indication information is used to indicate that the anchor carrier is allowed to be selected, and the random access resource selection indication information on the carrier indicates that a certain random access resource on the anchor carrier is allowed to be selected. Then the terminal selects the random access resource to perform random access.

[0154] Optionally, if the first information includes carrier selection information, the step of the terminal performing operations related to accessing the network-side device based on the first information includes one or more of the following:

[0155] The terminal selects an anchor carrier to perform random access based on the anchor carrier selection information;

[0156] The terminal selects random access resources on the anchor carrier based on the selection information of random access resources on the anchor carrier to perform random access;

[0157] The terminal selects a non-anchor carrier to perform random access based on the selection information of the non-anchor carrier;

[0158] The terminal selects random access resources on the non-anchor carrier to perform random access based on the selection information of random access resources on the non-anchor carrier.

[0159] In this embodiment, based on the information content included in the carrier selection information, the terminal can select an anchor carrier or a non-anchor carrier for random access, and can further select random access resources on the anchor carrier or random access resources on the non-anchor carrier for random access, which helps to improve the terminal's access efficiency.

[0160] Optionally, when the system message from the network-side device provides access control-related information, the access control information indicated by the first information has a higher priority than the access control-related information provided by the system message; and / or,

[0161] When the network-side device provides carrier selection-related information in its system messages, the priority of the carrier selection information indicated by the first information is higher than the priority of the carrier selection-related information provided in the system messages.

[0162] For example, if the access control information carried in the paging message includes an indication that access is prohibited via the anchor carrier, and the selection probability information of the anchor carrier in the system message is 1, then the terminal will prioritize obeying the access control information in the paging message. That is, the terminal believes that it is prohibited from accessing the network via the anchor carrier, or the terminal believes that the selection probability of the anchor carrier is 0. Therefore, the terminal will not select the anchor carrier to perform random access operation.

[0163] For example, if the carrier selection information carried in the paging message includes anchor carrier selection information (e.g., the selection probability is 0), and the anchor carrier selection probability information in the system message is 0.1, then the terminal will prioritize the carrier selection information in the paging message. That is, the terminal considers the anchor carrier selection probability to be 0, and therefore the terminal will not select the anchor carrier to perform random access operation.

[0164] Understandably, the process of a terminal obtaining system messages introduces a certain delay. In this embodiment, the access control information and / or carrier selection information indicated in the first information are given a higher priority than the access control information and / or carrier selection information provided by the system messages. This avoids terminal delays and enables the terminal to quickly access the network.

[0165] Please refer to Figure 3, which is a second flowchart of an access processing method provided in an embodiment of this application. The method is applied to a network-side device. As shown in Figure 3, the method includes the following steps:

[0166] Step 301: The network-side device sends first information to the terminal; wherein the first information includes one or more of the following:

[0167] Access control information;

[0168] Carrier selection information.

[0169] For example, when the network-side device detects that the system capacity is limited, which can also be understood as the network-side device (will) no longer be able to accept terminal access, the network-side device sends the first information to the terminal. For example, the first information includes access control information, which may indicate that the system capacity is limited.

[0170] Optionally, the access control information includes one or more of the following:

[0171] System capacity indication information;

[0172] Access indication information; wherein, the access indication information is used to indicate that access is prohibited or access is permitted;

[0173] Access time information; wherein, the access time information is used to indicate the time information during which access is prohibited or allowed.

[0174] Optionally, the system capacity indication information includes any one of the following:

[0175] System capacity limited indication information;

[0176] The system capacity is not limited.

[0177] Optionally, the access indication information includes one or more of the following:

[0178] Community access indication information;

[0179] Carrier access indication information;

[0180] Service access instruction information.

[0181] Optionally, the access time information includes one or more of the following:

[0182] Access time information for the community;

[0183] Carrier access time information;

[0184] Information on the service access time.

[0185] Optionally, the carrier selection information includes one or more of the following:

[0186] Anchor carrier selection information;

[0187] Selection information for random access resources on the anchor carrier;

[0188] Selection information for non-anchor carriers;

[0189] Selection information for random access resources on non-anchor carriers.

[0190] Optionally, the carrier selection information includes one or more of the following:

[0191] Carrier selection indication information; wherein the carrier selection information is used to indicate whether a carrier is allowed to be selected or not;

[0192] Carrier selection probability information;

[0193] Selection indication information for random resources on a carrier; wherein, the selection indication information for random access resources on a carrier is used to indicate whether random access resources on the carrier are allowed to be selected or prohibited from being selected;

[0194] Information on the selection probability of random resources on a carrier wave.

[0195] Optionally, the first information may be carried via any of the following messages:

[0196] Paging messages;

[0197] Random access response message;

[0198] Connection establishment rejected message;

[0199] Connection reconstruction refused message.

[0200] Optionally, when the system message from the network-side device provides access control-related information, the access control information indicated by the first information has a higher priority than the access control-related information provided by the system message; and / or,

[0201] When the network-side device provides carrier selection-related information in its system messages, the priority of the carrier selection information indicated by the first information is higher than the priority of the carrier selection-related information provided in the system messages.

[0202] It should be noted that the access processing method for network-side devices provided in this application corresponds to the access processing method for terminal-side devices described above. The relevant concepts and specific implementation processes involved in this application can be referred to the description in the terminal-side method embodiments described above. To avoid repetition, this embodiment will not repeat them.

[0203] In this embodiment, the network-side device sends first information to the terminal. The first information includes at least one of access control information and carrier selection information. The terminal can then perform operations related to accessing the network-side device based on the first information, such as accessing the network-side device or not accessing the network-side device. Thus, the terminal can determine whether it can access the network-side device based on the first information, avoiding unnecessary access attempts and network congestion.

[0204] Please refer to Figure 4a, which is a flowchart of a third access processing method provided in an embodiment of this application. As shown in Figure 4a, the method includes the following steps:

[0205] Step 410a: The base station detects that the system capacity is limited, which can be understood as the base station (will) no longer be able to accept terminal access. Then the base station provides access control information (such as access prohibition information) to the terminal.

[0206] Step 410b: If the base station detects that the system capacity is not limited, which can be understood as the base station being able to accept more terminals, then the base station provides access control information (such as access permission information) to the terminals.

[0207] It should be noted that the above behavior is based on base stations.

[0208] Step 411a (or 411b): The base station provides access control information to the terminal, which assists the terminal in accessing the network. The access control information may be carried via a paging message, a random access response message, a connection establishment rejection message, or a connection reconstruction rejection message.

[0209] For example, a new information field can be introduced into the existing paging-NB message, and the newly introduced information field is used to carry the access control information.

[0210] The access control information includes one or more of the following:

[0211] (1) System capacity indication information;

[0212] The system capacity indication information is used to indicate whether the system capacity is limited or not.

[0213] For example, the system capacity indication information may be a one-bit indication information; for instance, when this information field exists or is set to "1", it is used to indicate that the system capacity is limited. When this information field does not exist or is set to "0", it is used to indicate that the system capacity is not limited.

[0214] For example, when the system capacity indication information indicates that the system capacity is limited, the terminal considers itself to be prohibited from accessing the network; when the system capacity indication information indicates that the system capacity is not limited, the terminal considers itself to be allowed to access the network.

[0215] (2) Access indication information;

[0216] The access indication information is used to indicate whether access is prohibited or allowed.

[0217] (3) Access time information;

[0218] For example, the access time information is used to indicate time information for prohibiting access and / or time information for allowing access. For instance, the access time information may indicate that access is prohibited for 1 minute. Or, for another example, the access time information may indicate that access is prohibited between 12:00 and 12:01.

[0219] Optionally, the access indication information includes one or more of the following:

[0220] (a) Cell access indication information;

[0221] The cell access indication information is used to indicate whether cell access is disabled or not (or allowed).

[0222] For example, the cell access indication information is a 1-bit indication information. When it is set to "barred", the terminal believes that the cell is disabled; when it is set to "not barred", the terminal believes that the cell is not disabled.

[0223] (b) Carrier access indication information;

[0224] The carrier access indication information is used to indicate whether the carrier is disabled or not (or allowed).

[0225] Furthermore, the carrier indicated by the carrier access indication information may be an anchor carrier and / or a non-anchor carrier.

[0226] As an example, the carrier access indication information can be a bitmap; each bit in the bitmap corresponds to a carrier, and the value of the bit is used to indicate whether the corresponding carrier is prohibited or permitted. For example, a value of "1" indicates that the corresponding carrier is prohibited from access, and a value of "0" indicates that the corresponding carrier is permitted to access.

[0227] As another example, the carrier access indication information can be a list; each element of the list corresponds to a carrier and indicates whether the corresponding carrier is disabled or enabled.

[0228] (c) Service access indication information;

[0229] The service mentioned can be a calling service or an emergency service, etc.

[0230] The service access indication information is used to indicate whether a service is prohibited from accessing or is allowed to access; or the service access indication information is also used to indicate the disabling factor of the service, which can be understood as the reason why the service is prohibited.

[0231] Optionally, the access time information includes one or more of the following:

[0232] (1) Access time information of the cell;

[0233] For example, the access time information of the cell is used to indicate the time information when access is prohibited and / or the time information when access is permitted in the cell;

[0234] (2) Carrier access time information;

[0235] For example, the carrier access time information is used to indicate the time information when the carrier is prohibited from access and / or the time information when access is permitted;

[0236] (3) Service access time information;

[0237] For example, the access time information of the service is used to indicate the time information when the service is prohibited from access and / or the time information when access is permitted.

[0238] Step 412a: The terminal receives the aforementioned access control information. Based on the access control information, the terminal performs network access-related operations, such as delaying network access; or...

[0239] Step 412b: The terminal receives the aforementioned access control information. Based on the access control information, the terminal accesses the network.

[0240] It should be noted that the terminal has the capability to receive access control information via paging messages. Furthermore, this capability to receive access control information via paging messages can be a capability without signaling reporting. Furthermore, the prerequisite capability for this capability to receive access control information via paging messages can be that the terminal supports voice functionality.

[0241] Furthermore, the access control information has a higher priority than the access control-related information provided in the system message. For example, if the access control information carried in the paging message includes an indication that access via the anchor carrier is prohibited, and the selection probability information of the anchor carrier carried in the system message is 1, then the terminal prioritizes the access control information in the paging message; that is, the terminal considers itself prohibited from accessing the network via the anchor carrier, meaning the terminal considers the selection probability of the anchor carrier to be 0.

[0242] In this embodiment, the terminal can determine whether it can access the network based on the access control information, thereby avoiding unnecessary access attempts by the terminal and helping to save terminal power consumption.

[0243] Please refer to Figure 4b, which is a flowchart of an access processing method provided in an embodiment of this application. As shown in Figure 4b, the method includes the following steps:

[0244] Step 420a: The base station detects that the system capacity is limited, for example, the capacity of carrier 1 is limited, which can be understood as carrier 1 (will) no longer be able to accept terminal access. Then the base station provides carrier selection information to the terminal (for example, instructing the terminal to switch from carrier 1 to carrier 2).

[0245] Step 420b: If the base station detects that the system capacity is not limited, for example, if the capacity of carrier 1 is limited, it can be understood that carrier 1 can accept more terminal access. Then the base station provides carrier selection information to the terminal (for example, instructing the terminal to switch from carrier 2 to carrier 1).

[0246] It should be noted that the above behavior is based on base stations.

[0247] Step 421a (or 421b): The base station provides carrier selection information to the terminal, which assists the terminal in accessing the network. The carrier selection information is carried via a paging message; or via a random access response message; or via a connection establishment rejection message; or via a connection reconstruction rejection message.

[0248] For example, a new information field can be introduced into the existing paging-NB message, and the newly introduced information field is used to carry the carrier selection information.

[0249] The carrier selection information includes one or more of the following:

[0250] (1) Anchor carrier selection information;

[0251] For example, when the capacity of the anchor carrier is limited, the anchor carrier selection information indicates that the selection probability or access probability of the anchor carrier is 0.

[0252] (2) Selection information of random access resources on anchor carrier;

[0253] For example, the selection information of random access resources on the anchor carrier can be a list. Each item in the list corresponds to a random access resource on the anchor carrier, indicating the selection probability of that random access resource, which can be understood as the probability of accessing the network using the corresponding random access resource.

[0254] (3) Selection information for non-anchor carriers;

[0255] For example, the selection information for the non-anchor carrier can be a list. Each item in the list corresponds to a non-anchor carrier and indicates the selection information for the non-anchor carrier.

[0256] For example, when the capacity of the non-anchor carrier is limited, the selection information of the non-anchor carrier indicates that the selection probability or access probability of the non-anchor carrier is 0.

[0257] (4) Selection information of random access resources on non-anchor carriers;

[0258] For example, the selection information of random access resources on the non-anchor carrier can be a list. Each item in the list corresponds to a random access resource on the non-anchor carrier and indicates the selection probability of the corresponding random access resource, which can be understood as the probability of accessing the network using the corresponding random access resource.

[0259] It should be noted that the selection information mentioned above can be selection probability information. For example, the selection probability information of the target object (such as anchor carrier, non-anchor carrier, random access resources on anchor carrier, or random access resources on non-anchor carrier), such as selection probabilities of 0, 1 / 6, 1 / 8, or 1 / 2.

[0260] Alternatively, the selection information described above can be availability information. For example, availability information of the target object (such as an anchor carrier, a non-anchor carrier, random access resources on an anchor carrier, or random access resources on a non-anchor carrier) can be used to indicate that the target object can be selected.

[0261] Alternatively, the selection information mentioned above can be disabling information. For example, disabling information can be used to indicate that a target object (such as an anchor carrier, a non-anchor carrier, a random access resource on an anchor carrier, or a random access resource on a non-anchor carrier) cannot be selected.

[0262] Furthermore, the aforementioned available or disabled information can be a single-bit indication. For example, setting it to "true", "setup", or "1" indicates that the information is available. Setting it to "false", "release", or "0" indicates that the information is disabled.

[0263] Optionally, the carrier selection information has a higher priority than the carrier selection information provided in the system message. For example, if the carrier selection information carried in the paging message includes anchor carrier selection information (e.g., a selection probability of 0), and the anchor carrier selection probability information provided in the system message is 0.1, then the terminal prioritizes the carrier selection information in the paging message, that is, the terminal considers the anchor carrier selection probability to be 0.

[0264] It should be noted that when the aforementioned carrier selection information includes anchor carrier selection information, the carrier selection information may not include non-anchor carrier selection information. In this case, the non-anchor carrier selection information is obtained based on the anchor carrier selection information. For example, if the anchor carrier selection probability is 0, then the non-anchor carrier selection probability = 1 - anchor carrier selection probability, which is 1. Further, the non-anchor carrier selection probability = (1 - anchor carrier selection probability) / number of random access resources on the non-anchor carrier. Similarly, when the aforementioned carrier selection information includes non-anchor carrier selection information, the carrier selection information may not include anchor carrier selection information. In this case, the anchor carrier selection information can be obtained based on the non-anchor carrier selection information.

[0265] Step 422a: The terminal receives the carrier selection information. Based on the carrier selection information, the terminal selects an available carrier (e.g., carrier 2) to perform random access; or,

[0266] Step 422b: The terminal receives the carrier selection information. Based on the carrier selection information, the terminal selects an available carrier (e.g., carrier 1) to perform random access.

[0267] It should be noted that the terminal has the ability to receive carrier selection information via paging messages. Furthermore, a prerequisite capability of the terminal is that it can perform random access on a non-anchor carrier, i.e., the terminal has multiCarrier-NPRACH capability.

[0268] Wherein, the terminal selects an available carrier based on the carrier selection information, including one or more of the following:

[0269] (a) Based on the anchor carrier selection information, the terminal selects the anchor carrier;

[0270] Wherein, the anchor carrier selection information is carried through the carrier selection information; or, when the carrier selection information carries non-anchor carrier selection information, the anchor carrier selection information is obtained based on the non-anchor carrier information;

[0271] Furthermore, when the anchor carrier selection information indicates the anchor carrier selection probability, the anchor carrier is selected based on the selection probability to perform random access;

[0272] Furthermore, if the anchor carrier selection information indicates that the anchor carrier is disabled, the anchor carrier is not selected to perform random access based on the anchor carrier disablement information.

[0273] Furthermore, when the anchor carrier selection information indicates the availability of the anchor carrier, the anchor carrier is selected based on the availability of the anchor carrier to perform random access.

[0274] (b) Based on the selection information of the non-anchor carrier, the terminal selects a non-anchor carrier;

[0275] Wherein, the selection information of the non-anchor carrier is carried through the carrier selection information; or, when the carrier selection information carries the selection information of the anchor carrier, the selection information of the non-anchor carrier is obtained based on the selection information of the anchor carrier.

[0276] Furthermore, if the selection information of the non-anchor carrier indicates the selection probability of the non-anchor carrier, the non-anchor carrier is selected based on the selection probability to perform random access;

[0277] Furthermore, if the selection information of the non-anchor carrier indicates the disabling information of the non-anchor carrier, the non-anchor carrier is not selected to perform random access based on the disabling information of the non-anchor carrier;

[0278] Furthermore, when the selection information of the non-anchor carrier indicates the availability information of the non-anchor carrier, the non-anchor carrier is selected based on the availability information of the non-anchor carrier to perform random access.

[0279] In this embodiment, when system capacity is limited, the base station provides carrier selection information to the terminal via paging messages. The terminal then selects a suitable carrier to access the network based on this carrier selection information. The terminal can switch to other carriers for access when the system capacity of a particular carrier is limited, thereby solving the problem of the terminal being unable to access the network under limited system capacity and achieving a gain in increasing the probability of terminal access.
