Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an access indication method and related apparatus. Background Technology

[0002] When users use their terminals to make calls or access the internet, they may encounter issues such as being unable to reach the recipient or network interruptions. Taking being unable to reach the recipient as an example, analysis reveals that the cause of this problem is that the terminal is restricted to using voice services on a specific network, but the terminal is unaware of this restriction. Summary of the Invention

[0003] This application provides an access indication method and related apparatus, the purpose of which is to enable a terminal to clearly understand the limitations of its use of network services.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] Firstly, this application provides an access indication method, which can be executed by a terminal, or by a component configured in the terminal (such as a circuit, chip, or chip system), or by a logic module or software capable of implementing all or part of the terminal's functions. This application does not limit the scope of the method. The following description uses a terminal as an example.

[0006] The access indication method includes: receiving a first message, the first message indicating the availability of capabilities of one or more radio access networks, the capabilities including voice capabilities and / or data capabilities, and the multiple radio access networks having different network standards.

[0007] In the above technical solution, the network device sends a first message, which is used to indicate the availability of one or more wireless access network capabilities, including voice capabilities and / or data capabilities. This enables the terminal to clearly understand whether it is restricted from using the network's voice and data capabilities, that is, to understand the restrictions on its use of wireless access network services. It also avoids the terminal from initiating a registration request to the network device that restricts the use of voice or data capabilities in order to use the restricted capabilities, effectively reducing the signaling interaction of such registration requests and reducing power consumption.

[0008] In some possible implementations, when the first message indicates that the capability of the radio access network is unavailable, the first message is also used to indicate a first duration, which is the duration for which the capability of the radio access network is unavailable.

[0012] In some possible implementations, the utilization control information unit further includes a second field, which indicates whether access to multiple radio access networks is restricted; when the second field indicates that access to the radio access network is not restricted, the first field indicates the availability of the radio access network's capabilities.

[0013] In some possible implementations, the method further includes: when the user equipment is set to prioritize the first capability and the first message indicates that the first capability of the first radio access network is unavailable, prohibiting the measurement of the channel quality of the cell under the first radio access network, or measuring the channel quality of the cell under the first radio access network but not transmitting the channel quality of the cell under the first radio access network, and not reselecting to the cell under the first radio access network; wherein the first capability is a voice capability and / or a data capability.

[0014] In some possible implementations, the first message is also used to indicate that, in the case of a first duration, the measurement of the channel quality of the cell under the first radio access network is prohibited during the first duration, or the channel quality of the cell under the first radio access network is measured during the first duration, but the channel quality of the cell under the first radio access network is not transmitted, and the cell under the first radio access network is not reselected during the first duration, wherein the first duration is the duration during which the first capability of the first radio access network is unavailable.

[0015] In some possible implementations, the method further includes: setting the user equipment to prioritize a third capability when the user equipment is configured to use a second capability first and a first message indicates that the second capability of multiple radio access networks is unavailable; wherein the second capability and the third capability are voice capabilities or data capabilities, and the second capability and the third capability are different.

[0016] In some possible implementations, the first message is also used to indicate, in the case of a first duration of multiple radio access networks, a second duration of which the user equipment is set to use the third capability as the priority, the second duration being one of the first durations of multiple radio access networks, and the first duration of the radio access network being the duration during which the capability of the radio access network is unavailable.

[0017] Secondly, this application provides an access indication method, which can be executed by a network device, or by a component (such as a circuit, chip, or chip system) configured in the network device, or by a logic module or software capable of implementing all or part of the functions of the network device.

The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0055] The "multiple" mentioned in the embodiments of this application refers to two or more.

[0056] The technical solutions provided in this application can be applied to communication systems, which can be second-generation (2G) communication systems, third-generation (3G) communication systems, LTE systems, fifth-generation (5G) communication systems, LTE and 5G hybrid architectures, 5G New Radio (5G NR) systems, and new communication systems that will emerge in the future development of communication, etc. This application does not make any specific limitations on these.

[0057] like Figure 1 As shown, the communication system includes a first device 100 and a second device 200. The first device 100 can be a network-side device used to provide network communication functions; in some cases, it is also called a network device or network element. A network device can typically be a base station (including functional units of a base station, or a combination of functional units of base stations) or a core network unit. The core network unit can be a functional unit within the core network, including but not limited to access and mobility management function (AMF) units or session management function (SMF) units. The second device 200 can be a device accessing the network, typically a terminal.

[0058] In this embodiment, the base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. The base station can include one or more co-located or non-co-located transmission reception points (TRPs). The base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radioaccess network (CRAN) scenario. The base station can communicate with the terminal 200, or it can communicate with the terminal 200 through a relay station. The terminal can communicate with multiple base stations using different technologies. For example, the terminal can communicate with base stations that support LTE networks, base stations that support 5G networks, and can also establish dual connections with both LTE and 5G base stations.

[0059] In the embodiments of this application, the terminal can be of various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. The terminal may also be referred to as terminal equipment, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, wireless communication equipment, UE agent, or UE device, etc. The terminal can also be a fixed terminal or a mobile terminal.

[0060] In some embodiments, the communication system may also include other devices that communicate with the first device and / or the second device, which is not a limitation of this application.

[0061] To facilitate understanding, the concepts involved in this application will be explained below.

[0062] 1. Network standard refers to the type of network. In this application, network standard mainly refers to the type of mobile communication network. For example, network standard may include second generation (2G), Global System for Mobile Communications (GSM), third generation (3G), code division multiple access (CMDA), 4G, LTE, EPS, 5G, NR, 5GS, etc.

[0063] 2. Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN are radio access technologies for different generations of mobile communication networks. The following is a brief introduction to them:

[0064] Sat-NG-RAN is a radio access network for 5G satellite non-terrestrial networks. It is based on 5G technology and supports interoperability with terrestrial 5G networks.

[0065] Sat-E-UTRAN is a radio access network for 4G satellite non-terrestrial networks. It is also based on LTE technology and can interoperate with terrestrial 4G networks to expand the coverage of 4G services.

[0066] NG-RAN is a next-generation radio access network and a core component of 5G NR (new radio).

[0067] E-UTRAN is an Evolutionary Universal Terrestrial Radio Access Network, which is the radio network portion of LTE and LTE-A systems.

[0068] UTRAN (UMTS terrestrial radio access network) is the radio access network component of the 3G Universal Mobile Telecommunications System (UMTS), responsible for functions such as radio resource management and user data transmission.

[0069] GERAN stands for GSM EDGE radio access network, which is the radio access component of the Global System for Mobile communication (GSM) / enhanced data rate for GSM evolution (EDGE).

[0070] 3. The terminal supports multiple radio access technologies (RATs), such as those under 2G, 3G, 4G, and 5G network standards. This multi-mode coexistence capability enables the terminal to maintain service continuity and stability when moving between different access systems. However, there are still scenarios where it is necessary to restrict the terminal's access to certain networks. Based on this, 3GPP introduced a RAT access restriction scheme through the "enhancement of controlling RAT utilization" in the work item description (WID). Network devices can configure the RAT list through the RAT utilization control information element, which can include multiple RATs and indicate whether access to multiple RATs is restricted.

[0071] 4. User Equipment (UE) usage settings are primarily used to indicate the user equipment's preference between voice and data services. They include the following two settings:

[0072] Voice centric: If the user device prefers voice services, then voice is prioritized. This means that if the network cannot simultaneously meet both voice and data needs, the user device will prioritize voice services.

[0073] Data centric: If the user device prefers data services, then data centric is set. This means that if the network cannot simultaneously meet both voice and data needs, the user device will prioritize data services.

[0074] Taking voice-first mode as an example, when a user equipment (UE) is operating in voice-first mode but fails to obtain IP multimedia subsystem (IMS) services, it can downgrade its network mode in order to obtain voice services. For instance, if a UE cannot obtain IMS services on NR, it will disable NR and obtain voice services from LTE.

[0075] The descriptions of the concepts involved in this application are merely for the purpose of facilitating understanding of the technical solutions in this application and do not constitute any limitation on this application.

[0076] Taking mobile phones as an example, when users make calls using their devices, there is a problem where the called party cannot get through. For instance, Figure 2 In the big data list shown, the probability of being unable to reach someone by phone is relatively high in some cases, such as 10.09% and 16.16%. This results in 2.5% or even 16.12% of users experiencing being unable to reach someone by phone, which has a significant impact on users and leads to a poor user experience.

[0077] Analysis revealed that the inability to connect to a caller typically occurs when the phone is running on a 5G network; voice calls function normally when the phone is running on an LTE network. This is because the terminal is restricted to using voice services on the LTE network, but the terminal is unaware of this restriction. In some application scenarios, the terminal's subscriber identity module card (SIM card) is subject to restrictions, allowing voice services only on LTE networks. In other application scenarios, the terminal uses an IoT card, which only supports voice services on LTE networks.

[0078] For the procedure regarding the issue of a terminal being unable to make a call on a 5G network, please refer to [link / reference]. Figure 3 , Figure 3This diagram illustrates a process for resolving the issue of a missed call. For example, the terminal is in voice-first mode.

[0079] like Figure 3 As shown, after the terminal successfully registers with 5G through step 1, it can send a PDU (protocol data unit) session establishment request to the NR through step 2. The data network name (DNN) carried in this request is IMS. The NR carries the DNN as CMDTJ in the PDU acceptance message it replies in step 3. The terminal executes step 4 to determine that the requested DNN and the received DNN do not match, and then releases the PDU through step 5.

[0080] Because the terminal is in voice-first mode, failure to register IMS in this mode will disable NR for a period of time and trigger the terminal to drop LTE. Therefore, the terminal disables NR in step 6 and starts a timer, for example, with a duration of 10 minutes. The terminal also successfully registers with LTE in step 7. In step 8, the terminal sends a Packet Data Network (PDN) establishment request to LTE, carrying the Access Point Name (APN) as IMS. LTE responds with a PDN acceptance message in step 9, also carrying the APN as IMS. Since the APN requested by the terminal matches the APN received, voice calls can proceed normally on LTE, and the called party can be reached.

[0081] After the timer started by the terminal in step 6 times out, the terminal can attempt to rejoin NR in step 10. The terminal successfully registers for 5G in step 11, and then sends a PDU session establishment request to NR in step 12. This request carries the DNN as IMS. The NR replies with a PDU acceptance message in step 13, carrying the DNN as CMDTJ. The terminal executes step 14 to determine that the requested DNN and the received DNN do not match. Therefore, it releases the PDU again in step 15. Since it is in voice-first mode, the lack of IMS registration can disable NR for a period of time in step 16, triggering the terminal to drop LTE. Subsequent steps are described in steps 7-10 above.

[0082] As can be seen from the above process: Because the terminal is in voice-first mode, it does not register IMS on the 5G network. It can switch from 5G to LTE, but after a period of time, such as 10 minutes, the terminal will return to the 5G network to retry IMS registration. Each time it returns to the 5G network, IMS registration fails, and it switches back to LTE, repeating this process. During the IMS registration process on the 5G network, if... Figure 3 During the T1 and T2 periods shown, the terminal may experience issues where it cannot connect to incoming calls.

[0083] To address this, embodiments of this application provide an access indication method in which a network device indicates to a terminal whether one or more wireless access networks provide voice capabilities and / or data capabilities, so that the terminal can determine whether its use of the network's voice and data capabilities is restricted through information from the network device.

[0084] Figure 4 A flowchart illustrating an access indication method according to an embodiment of this application is shown.

[0085] like Figure 4 As shown, the access indication method includes:

[0086] S401, the network device sends the first message, and the corresponding terminal receives the first message.

[0087] The first message is used to indicate the availability of capabilities of one or more radio access networks, including voice and / or data capabilities.

[0088] Understandably: Taking a radio access network as an example, the first message indicates the availability of the capabilities of the radio access network, which may include: the first message indicating whether the radio access network provides voice capabilities, and / or whether it provides data capabilities.

[0089] In some embodiments, the timeliness of the first message indicating the availability of the capabilities of one or more radio access networks can be fixed, i.e., the first message indicates the availability of one or more radio access networks within a fixed time period, which can be in the form of days, hours, minutes, seconds, etc. In one example, the first message indicates that the voice capability of a wireless communication network is unavailable within a day; in another example, the first message indicates that the data capability of a wireless communication network is unavailable within 3 hours.

[0090] In other embodiments, the first message may include a first duration, which indicates the duration for which the capability of the radio access network is unavailable; that is, the first duration is the duration for which the capability of the radio access network is unavailable. In one implementation, the first duration is used to indicate the duration for which the capability of one radio access network is unavailable. For example, the first message indicates that the capability of three radio access networks is unavailable, and the first message also includes three first durations, each of which may indicate the duration for which the capability of one radio access network is unavailable. In another implementation, the first message includes a first duration that indicates the duration for which the capability of one or more radio access networks is unavailable. For example, the first message indicates that the capability of three radio access networks is unavailable, and the first message includes a first duration that indicates that the capability of the three radio access networks is unavailable within a first duration.

[0091] In some embodiments, the first duration can be a fixed duration or one or more time units, such as days, hours, minutes, seconds, etc. When the first duration is indicated in terms of time units, the first message also includes a specific numerical value for that time unit. In one example, if the first message indicates that the capability of a wireless access network is unavailable for one day, the first message includes a first duration in days and includes the value 1 to indicate a time unit.

[0092] Multiple radio access networks may have different network standards. For example, multiple radio access networks may include: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, GERAN, but this does not constitute a limitation on the network standard of the radio access network indicated by the first message.

[0093] For example, in multiple radio access networks such as Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN, the first message may indicate the availability of capabilities of one or more of Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN, which may include voice capabilities and / or data capabilities.

[0094] In this embodiment of the application, the network device sends a first message to the terminal. The first message is used to indicate the availability of the capabilities of one or more wireless access networks, including voice capabilities and / or data capabilities. This enables the terminal to clearly understand whether it is restricted from using the network's voice and data capabilities, and also avoids the terminal from initiating a registration request to the network device that restricts the use of voice or data capabilities, effectively reducing the signaling interaction of such registration requests and reducing power consumption.

[0095] For example, when a wireless access network restricts a terminal's use of voice capabilities, once the terminal acknowledges this restriction via a first message, it can reduce or eliminate the use of the wireless access network's voice capabilities, thereby decreasing the frequency of missed calls and improving the user experience.

[0096] In some embodiments, the first message includes a utilization control information element of a radio access network, the utilization control information element including a first field for indicating the availability of the capabilities of one or more radio access networks.

[0097] In one implementation, the Radio Access Network (RAT) utilization control information element includes at least two fields: a first field indicating the availability of one or more radio access networks, and a second field indicating whether access to multiple radio access networks is restricted. Optionally, the first field further includes a first duration, which is the duration for which the capability of the one or more radio access networks indicated by the first field is unavailable. The first duration corresponds one-to-one with the radio access networks indicated by the first field.

[0098] Figure 5 and Figure 6 The diagram illustrates two structural schematics of the utilization control information unit of the wireless access network provided in this implementation.

[0099] Figure 5 and Figure 6 The utilization control information unit of the wireless access network shown is illustrated with an example of a single line containing 8 bits, illustrating its structure. Figure 5 Each of octet1 through octet13 shown indicates 8 bits. Figure 6 Each of octet1 through octet20 shown indicates 8 bits. In a single line, from right to left, the bits are numbered 1 through 8.

[0100] For example, such as Figure 5 As shown, in the utilization control information unit of the radio access network, the second field indicates whether access to the six radio access networks—Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN—is restricted. Optionally, each bit in the second field indicates whether access to a radio access network is restricted, as shown in (octet4, bit 3) to (octet4, bit 8). A bit value of 1 indicates that the corresponding radio access network is restricted, a bit value of 0 indicates that the corresponding radio access network is not restricted, and vice versa, indicating no restriction.

[0101] Optionally, the second field includes six bits, each corresponding to one of the six radio access networks: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN. That is, the position of the six bits in the radio access network utilization control information unit is used to indicate a radio access network, and the value of the bits is used to indicate whether a radio access network is restricted.

[0102] For example, the position (octet 4, bit 5) in the utilization control information unit of the radio access network is used to indicate Sat-E-UTRAN. A value of 0 indicates that Sat-E-UTRAN is not restricted from access, and a value of 1 indicates that Sat-E-UTRAN is restricted from access.

[0103] In the utilization control information unit of the radio access network, the first field can indicate the availability of voice and data capabilities of the six radio access networks: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN. It can also indicate the duration during which the voice or data capabilities of the six radio access networks are unavailable, i.e., the first duration corresponding to each of the six radio access networks: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN.

[0104] In some embodiments, when the first field indicates the availability of voice and data capabilities of a radio access network, and when indicating the duration for which voice or data capabilities are unavailable, the first field includes a 3-bit Radio Access Network Identifier (RATID), a 1-bit voice available, a 1-bit data available, a 2-bit time unit, and a 5-bit duration value. Of course, the number of bits occupied by the Radio Access Network Identifier, voice available, data available, time unit, and duration value is not limited thereto.

[0105] The RAT ID is used to indicate the radio access network, such as the ID of Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, or GERAN.

[0106] A value of 0 for both "voice available" and "data available" indicates that the capability is not available, while a value of 1 indicates that the capability is available; the reverse is also true, and there are no restrictions.

[0107] The time unit can be seconds, minutes, hours, days, etc., with no restrictions. The duration value indicates the number of time units. It can be understood that the time unit and duration value together indicate the initial duration. That is, the time unit and duration value together indicate the duration during which the data or voice capabilities of the radio access network are unavailable. In some cases, both the data and voice capabilities of a radio access network are available, and both the time unit and duration value can be 0 or other meaningless values.

[0108] In one example, the RAT ID is Sat-NG-RAN, voice available is 0, data available is 1, the time unit is days, and the duration is 1. This indicates that the data capability of the radio access network is available to the terminal, but the voice capability is unavailable within a day.

[0109] Figure 5 The document illustrates the 72 bits comprised of octets 5 to 13, used to indicate the availability of voice and data capabilities for the six radio access networks: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN, as well as the duration for which voice or data capabilities are unavailable. Furthermore, the order of Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN is not limited to [specific order not specified in the original text]. Figure 5 The display method is not limited to RAT ID, voice available, data available, or the order of time unit and duration values. Figure 5 The way it is displayed.

[0110] Figure 5 The demonstrated radio access network (RAN) utilization control information unit clearly and completely indicates the availability of a RAN's voice and / or data capabilities, specifying the duration of unavailability while minimizing bit usage and improving message transmission efficiency. Furthermore, this combination of time units and duration values ​​allows for flexible and convenient indication of the unavailability duration of a RAN's voice or data capabilities.

[0111] Figure 6 The demonstrated radio access network utilization control information unit also exemplarily indicates, through a second field, whether access to the six radio access networks—Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN—is restricted. The method by which the second field indicates whether access to the six radio access networks—Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN—is restricted is similar to... Figure 5 The presentation method is the same, so it will not be repeated here.

[0112] Figure 6In the utilization control information unit of the radio access network shown, the first field can indicate the availability of voice and data capabilities of the six radio access networks: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN. It can also indicate the duration of voice capability unavailability and the duration of data capability unavailability separately.

[0113] Based on this, in some embodiments, when the first field indicates the availability of voice and data capabilities of a radio access network, and when indicating the duration of unavailability of voice and data capabilities, the first field includes a 3-bit Radio Access Network ID (RAT ID), a 1-bit voice availability, a 1-bit data availability, two sets of 2-bit time units, and two sets of 5-bit duration values. Of course, the number of bits occupied by the RAT ID, voice availability, data availability, time units, and duration values ​​is not limited to this.

[0114] For explanations of RAT ID, voice available, data available, time unit, and duration values, please refer to the aforementioned content, which will not be repeated here.

[0115] Of the two sets of 2-bit time units and two sets of 5-bit duration values, the first set of 2-bit time units and the first set of 5-bit duration values ​​can be used to indicate the duration for which a radio access network's voice capability is unavailable, and the second set of 2-bit time units and the second set of 5-bit duration values ​​can be used to indicate the duration for which a radio access network's data capability is unavailable; the reverse is also possible, and there is no limitation.

[0116] Figure 6 The demonstration shows one sorting method for Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN, but the sorting is not limited to this. Furthermore, the order of RAT ID, voice available, data available, time unit, and duration values ​​is also not limited. Figure 6 The way it is displayed.

[0117] Figure 6 The utilization control information unit of the wireless access network shown improves the comprehensiveness of the indication information by indicating the duration of unavailability of both voice and data capabilities of a wireless access network.

[0118] It should be noted that, Figure 5 and Figure 6 The first duration of the display includes one or more time units; if the first duration is a fixed duration, Figure 5 and Figure 6 The displayed time unit and duration value can be replaced with this fixed duration, or it can be configured without the time unit and duration value, in a manner agreed upon by the network device and the terminal.

[0119] In another implementation, the utilization control information unit of the radio access network includes at least two fields. The second field indicates whether access to multiple radio access networks is restricted, and the first field indicates the availability of the capabilities of the unrestricted radio access networks indicated by the second field. Optionally, the first field also includes a first duration, which is the duration during which the capabilities of the radio access networks indicated by the first field are unavailable. The first duration corresponds one-to-one with the radio access networks indicated by the first field.

[0120] Understandable: If a wireless access network is restricted, it means that its data and voice capabilities are unavailable to the terminal. To avoid the first field occupying too many bits, the second field indicates that when a wireless access network is restricted, the first field does not indicate the availability of the wireless access network's capabilities.

[0121] Figure 7 A schematic diagram of the structure of the utilization control information unit of the wireless access network provided in this implementation is shown.

[0122] Figure 7 The utilization control information unit of the wireless access network shown is also illustrated using an example of a single row containing 8 bits. Within a row, bits 1 through 8 are arranged from right to left.

[0123] Figure 7 The demonstrated radio access network utilization control information unit also exemplarily indicates, through a second field, whether access to the six radio access networks—Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN—is restricted. The method by which the second field indicates whether access to the six radio access networks—Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN—is restricted is similar to... Figure 5 The presentation method is the same, so it will not be repeated here.

[0124] In one example, Figure 7The demonstrated Sat-NG-RAN and NG-RAN have restricted access, while Sat-E-UTRAN, E-UTRAN, UTRAN, and GERAN have unrestricted access. Based on this, the first field indicates the availability of voice and data capabilities for Sat-E-UTRAN, E-UTRAN, UTRAN, and GERAN, as well as the duration for which voice or data capabilities are unavailable. This further reduces the number of bits occupied by the first field, thereby improving data transmission efficiency.

[0125] In some embodiments, when the first field indicates the availability of voice and data capabilities of a radio access network, and when indicating the duration for which voice or data capabilities are unavailable, the first field includes a 3-bit Radio Access Network Identifier (RATID), a 1-bit voice available, a 1-bit data available, a 2-bit time unit, and a 5-bit duration value. Of course, the number of bits occupied by the Radio Access Network Identifier, voice available, data available, time unit, and duration value is not limited thereto.

[0126] For explanations of RAT ID, voice available, data available, time unit, and duration values, please refer to the aforementioned content, which will not be repeated here.

[0127] In other embodiments, when the first field indicates the availability of voice and data capabilities of a radio access network, and when indicating the duration of unavailability of voice and data capabilities, the first field includes a 3-bit Radio Access Network Identifier (RATID), a 1-bit voice available, a 1-bit data available, two sets of 2-bit time units, and two sets of 5-bit duration values. Of course, the number of bits occupied by the Radio Access Network Identifier, voice availability, data availability, time units, and duration values ​​is not limited to this.

[0128] For explanations of RAT ID, voice available, data available, time unit, and duration values, please refer to the aforementioned content, which will not be repeated here.

[0129] Of the two sets of 2-bit time units and two sets of 5-bit duration values, the first set of 2-bit time units and the first set of 5-bit duration values ​​can be used to indicate the duration for which a radio access network's voice capability is unavailable, and the second set of 2-bit time units and the second set of 5-bit duration values ​​can be used to indicate the duration for which a radio access network's data capability is unavailable; the reverse is also possible, and there is no limitation.

[0130] Figure 7 The displayed sorting methods are Sat-E-UTRAN, E-UTRAN, UTRAN, and GERAN, but the sorting is not limited to these. Furthermore, the order of RAT ID, voice available, data available, time unit, and duration values ​​is also not limited. Figure 7 The way it is displayed.

[0131] It should be noted that, Figure 7 The first duration of the display includes one or more time units; if the first duration is a fixed duration, Figure 7 The displayed time unit and duration value can be replaced with this fixed duration, or it can be configured without the time unit and duration value, in a manner agreed upon by the network device and the terminal.

[0132] Figures 5 to 7 In the demonstrated radio access network utilization control information unit, the first field includes a RAT ID to indicate a radio access network. In other embodiments, the first field may not include a RAT ID; instead, a radio access network may be indicated by the positions of voice available, data available, time unit, and duration value. That is, the positions of voice available, data available, time unit, and duration value correspond to a fixed radio access network. This configuration reduces the number of bits occupied by the RAT ID and can also improve data transmission efficiency.

[0133] For explanations of voice available, data available, time units, and duration values, please refer to the aforementioned content, which will not be repeated here.

[0134] For example, such as Figure 8 As shown, the utilization control information unit of the radio access network indicates whether access to the six radio access networks—Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN—is restricted. Following the order of GERAN, UTRAN, E-UTRAN, NG-RAN, Sat-E-UTRAN, and Sat-NG-RAN, bits from octet5 to octet11 sequentially indicate the availability of voice and data capabilities for each radio access network, as well as the duration of unavailability of voice or data capabilities.

[0135] Figure 8 The utilization control information unit of the wireless access network shown is also illustrated using an example of a single row containing 8 bits. Within a row, bits 1 through 8 are arranged from right to left.

[0136] like Figure 8 As shown, the 8 bits in octet5 and the first bit in octet6 are used to indicate the availability of GERAN's voice and data capabilities, as well as the duration for which GERAN's voice or data capabilities are unavailable.

[0137] Bits 2 through 8 in octet6, and bits 1 and 2 in octet7, are used to indicate the availability of the UTRAN’s voice and data capabilities, and the duration during which the UTRAN’s voice or data capabilities are unavailable.

[0138] Bits 3 through 8 of octet7 and bits 1 through 3 of octet8 indicate the availability of voice and data capabilities of the E-UTRAN, and the duration during which voice or data capabilities of the E-UTRAN are unavailable.

[0139] Bits 4 through 8 in octet8 and bits 1 through 4 in octet9 indicate the availability of voice and data capabilities of the NG-RAN, and the duration during which voice or data capabilities of the NG-RAN are unavailable.

[0140] Bits 5 through 8 of octet9 and bits 1 through 5 of octet10 indicate the availability of the Sat-E-UTRAN's voice and data capabilities, and the duration during which the Sat-E-UTRAN's voice or data capabilities are unavailable.

[0141] Bits 6 through 8 of octet10 and bits 1 through 6 of octet8 indicate the availability of the Sat-E-UTRAN's voice and data capabilities, and the duration during which the Sat-E-UTRAN's voice or data capabilities are unavailable.

[0142] It should be noted that, Figure 8 The first duration of the display includes one or more time units; if the first duration is a fixed duration, Figure 8 The displayed time unit and duration value can be replaced with this fixed duration, or it can be configured without the time unit and duration value, in a manner agreed upon by the network device and the terminal.

[0143] When the first field indicates the duration of unavailability of voice and data capabilities of a radio access network, the second field may include two sets of 2-bit time units and two sets of 5-bit duration values. Of the two sets of 2-bit time units and the two sets of 5-bit duration values, the first set of 2-bit time units and the first set of 5-bit duration values ​​can be used to indicate the duration of unavailability of voice capabilities of a radio access network, and the second set of 2-bit time units and the second set of 5-bit duration values ​​can be used to indicate the duration of unavailability of data capabilities of a radio access network; the reverse is also possible, and there is no limitation.

[0144] Figures 5 to 8 The demonstrated radio access network utilization control information unit indicates the availability of the radio access network's voice and data capabilities. When the radio access network utilization control information unit indicates only the availability of the radio access network's voice capabilities, or only the availability of the data capabilities, Figures 5 to 8 The utilization control information unit of the wireless access network shown may include only the voice available value or only the data available value.

[0145] In some embodiments, the first message may be included in a registration accept message, i.e., the network device sends a registration accept message to the terminal, which includes the first message. Optionally, the first message is a utilization control information element of the radio access network. The structure of the utilization control information element of the radio access network can be found in the foregoing description.

[0146] In other embodiments, the first message may also be included in a message sent by the network device to the terminal during the registration process. Optionally, the first message includes a first field indicating the availability of one or more radio access network capabilities. Optionally, the first field may also indicate the duration for which the radio access network capabilities are unavailable. The structure of the first field can be found in [reference needed]. Figures 5 to 8 The structure of the utilization control information unit of the wireless access network is shown.

[0147] In other embodiments, a new message may be added between the network device and the terminal; this message is the first message. Optionally, the first message may include an information unit, which includes a first field. The first field is used to indicate the availability of the capabilities of one or more radio access networks. Optionally, the first field may also be used to indicate the duration for which the capabilities of the radio access network are unavailable. The structure of the first field can be found in [reference needed]. Figures 5 to 8 The structure of the utilization control information unit of the wireless access network is shown.

[0148] The following example uses the first message, including the registration acceptance message, in conjunction with... Figure 9 and Figure 10 The access indication methods provided in the embodiments of this application are described in detail.

[0149] Figure 9 The demonstrated access indication method uses an example where the first message indicates that voice capabilities of Sat-NG-RAN and NG-RAN are unavailable for one day; however, this does not constitute a limitation on the content of the first message indication. Similarly, the example of a terminal initiating a UE attach procedure to LTE does not constitute a limitation on the objects to which the terminal executes the attach procedure. In the following text, LTE can be understood as network devices in the LTE system, such as access network devices and core network devices that support LTE; NR can be understood as network devices in the NR system, such as access network devices and core network devices that support 5G.

[0150] like Figure 9 As shown, the access indication method provided in this application embodiment includes:

[0151] S901, the terminal sends a request message, and the corresponding LTE receives the request message.

[0152] This can be understood as follows: When a terminal first connects to a network, it can perform an attach process. The terminal can first send an attach request message to the network to obtain network services. For example, when a terminal is powered on and needs to connect to a mobile network for operations such as making calls or accessing the internet, it can send an attach request message.

[0153] Once the terminal is attached to the network, it can send a request message to the network when updating its location. This request message is called a TAUrequest (tracking area update request) message. For example, when the terminal moves from one area to another, it can send a tracking area update request message to the network to inform it of its new location.

[0154] S902, LTE sends and receives messages, and correspondingly, the terminal receives and accepts messages.

[0155] The received message includes a first message, which indicates the availability of one or more radio access network capabilities. Optionally, it can also indicate the duration for which a radio access network capability is unavailable, which may refer to voice capability and / or data capability.

[0156] It is understandable that the availability of a radio access network (RAN) refers to whether a terminal can use the RAN's capabilities, and does not indicate that the RAN itself does not support voice or data services. Therefore, given the different limitations of SIM cards in different terminals, the content of the first message in the LTE-returned acceptance message may differ depending on the terminal's request message. In some scenarios, the content of the first message in the LTE-returned acceptance message may also be the same for different terminals.

[0157] After the terminal sends an attach request message, and the terminal and LTE perform authentication and authorization operations, LTE can send an attach accept message, which may include the first message.

[0158] After the terminal sends a TAU request message and the terminal and LTE perform a location update, LTE can send a Tracking Area Update Accept (TAU accept) message, which may include a first message.

[0159] The attached accept message and the tracking area update accept message belong to the registered accept message category.

[0160] It can be understood that the first message can be a utilization control information unit for the wireless access network, and its structure can be found in [reference needed]. Figures 5 to 8 The corresponding implementation details are not described here.

[0161] In Example 1, the first message indicates the availability and unavailability duration of Sat-NG-RAN and NG-RAN capabilities as follows: Sat-NG-RAN data capabilities are available, but voice capabilities are disabled for one day; NG-RAN data capabilities are available, but voice capabilities are disabled for one day. The first message also indicates that both voice and data capabilities are available for Sat-E-UTRAN, E-UTRAN, UTRAN, and GERAN.

[0162] S903: The terminal parses the first message to determine the availability and duration of unavailability of one or more radio access networks.

[0163] Upon receiving an acceptance message, the terminal retrieves the first message within it and parses it. This allows it to determine the availability and duration of unavailability of the capabilities of one or more radio access networks indicated by the first message. In essence, the terminal can use the moment it receives the first message as a start time to determine that, from that start time, it cannot use the capabilities of the radio access network during the specified unavailability period.

[0164] In Example 1 above, the terminal resolves that voice services from Sat-NG-RAN and NG-RAN are not provided to the terminal for one day, while data services are provided. Furthermore, voice and data services from Sat-E-UTRAN, E-UTRAN, UTRAN, and GERAN are all provided to the terminal. Thus, the terminal can explicitly use voice and data services from Sat-E-UTRAN, E-UTRAN, UTRAN, and GERAN, and can use data services from Sat-NG-RAN and NG-RAN, but cannot use voice services from Sat-NG-RAN and NGRAN for one day after receiving the acceptance message.

[0165] S904: The terminal determines whether the user's device is set to voice priority.

[0166] If the terminal determines that the user equipment is not set to voice priority, it can execute the following steps S905a, S906a, and S905b. If the terminal determines that the user equipment is set to voice priority, it can execute the following steps S907 to S910. The terminal may execute steps S905a and S906a, or step S905b, depending on its own state.

[0167] S905a: When the terminal is in connected state, it reports the channel quality of cells under Sat-NG-RAN and NG-RAN to LTE.

[0168] Once the terminal establishes a radio resource control (RRC) connection with LTE, the terminal is in connected mode. In connected mode, the terminal can measure the channel quality of surrounding serving cells and report the measurement results to the network side, facilitating a switch to a cell with better channel quality.

[0169] If the user equipment settings of the terminal are not voice-priority, but usually data-priority, then the fact that the voice services of Sat-NG-RAN and NG-RAN indicated by the first message are not provided to the terminal for a day will not affect the terminal's use of data services of cells under Sat-NG-RAN and NG-RAN. Therefore, the terminal's measurement of the channel quality of surrounding serving cells is not limited by the first message.

[0170] Understandably, the terminal can measure and report the channel quality of cells under Sat-NG-RAN and NG-RAN to LTE. Of course, when the surrounding serving cells are cells of other network standards, the terminal can also measure and report their channel quality.

[0171] S906a, Terminal access to NR cell.

[0172] In one application scenario, the terminal reports that the channel quality of the cell under NG-RAN is good, and the terminal can access the cell under NG-RAN under the action of the LTE handover command.

[0173] It is understandable that step S906a is an example of an NG-RAN cell having good channel quality and the LTE control terminal switching to that cell. This does not constitute a restriction on the way the terminal accesses the cell.

[0174] S905b: The terminal is in an idle state; reselect a cell under NR.

[0175] The RRC connection between the terminal and LTE is released, and the terminal is in an idle state. The terminal can reselect the cell camp according to the network reselection policy.

[0176] Similarly, since the user equipment settings of the terminal are not voice-first, the fact that the voice services of Sat-NG-RAN and NG-RAN indicated by the first message are not provided to the terminal for one day will not affect the terminal's use of data services of cells under Sat-NG-RAN and NG-RAN. Therefore, the terminal can reselect to cells under Sat-NG-RAN and NG-RAN.

[0177] In one application scenario, the terminal reselects to a cell under NG-RAN. Of course, this is just an example and does not constitute a limitation on cell reselection.

[0178] S907, Terminal startup restriction, and startup timer.

[0179] The terminal's user equipment is set to voice priority. The first message indicates that the Sat-NG-RAN and NG-RAN voice services will not provide the terminal with voice services that could affect the terminal's use of cells under Sat-NG-RAN and NG-RAN for one day. In order to avoid meaningless power consumption caused by the terminal attempting to switch to cells under Sat-NG-RAN or NG-RAN when it cannot use the voice services under Sat-NG-RAN and NG-RAN, the terminal can activate the restriction, which can reduce signaling interaction and avoid being unable to reach the user by calling, thereby improving the user experience.

[0180] The restriction can be understood as a restriction strategy, including: prohibiting the measurement and reporting of channel quality of cells under radio access networks where voice capability is unavailable as indicated by the first message, and prohibiting reselection to cells under radio access networks where voice capability is unavailable as indicated by the first message. The prohibition of measurement and reporting may include: not measuring, or measuring but not reporting to the network side.

[0181] For example, the first message indicates that the capability of the first radio access network is unavailable. This restriction may include: prohibiting the measurement of channel quality of cells under the first radio access network, or measuring the channel quality of cells under the first radio access network but not transmitting the channel quality of cells under the first radio access network to the network side, and may also include not reselecting to cells under the first radio access network. In Example 1, the first radio access network is Sat-NG-RAN and NG-RAN, and the capability is voice capability.

[0182] Optionally, the first message indicates the duration for which voice services on Sat-NG-RAN and NG-RAN are unavailable, based on which the terminal may also start a timer to keep track of the duration.

[0183] In some embodiments, the terminal may be configured with an identifier that indicates whether the terminal has activated a restriction policy. When the terminal activates a restriction policy, the identifier is set to a first value, such as 1, to indicate that the terminal has activated the restriction policy.

[0184] Under the restrictions imposed by the terminal's activation policy, the terminal can perform channel quality monitoring and reporting on cells under the second radio access network, or reselect cells under the second radio access network. This second access network is not a radio access network whose first message indication capability is unavailable. In Example 1, the second access network is a network other than Sat-NG-RAN and NG-RAN. The following steps S908a and S908b are described using LTE as an example of the second access network.

[0185] The terminal may execute steps S908a and S909a, or execute step S908b, depending on its own state.

[0186] S908a: When the terminal is in connected state, it reports the channel quality of the cell under LTE.

[0187] S909a, Terminal access to LTE-enabled cells.

[0188] S908b: The terminal is in an idle state; reselect a cell under NR.

[0189] The specific implementation methods of steps S908a, S909a, and S908b can be found in the aforementioned steps S905a, S906a, and S905b, and will not be elaborated here.

[0190] S910: When the timer reaches one day, the terminal is unrestricted.

[0191] After the timer has elapsed for the duration indicated by the first message that the capability is unavailable, the terminal can lift the aforementioned restrictions and resume channel quality monitoring and reselection for the cell under the radio access network where the capability is unavailable as indicated by the first message.

[0192] In Example 1, when the timer reaches the duration of one day, the terminal resumes channel quality monitoring and reselection for cells under Sat-NG-RAN and NG-RAN.

[0193] In some embodiments, the terminal may set the identifier to a second value, which is different from the first value, such as 0, to instruct the terminal to remove the restriction.

[0194] It should be noted that, Figure 9 The demonstration shows a scenario where the terminal prioritizes voice input.

[0195] In some embodiments, the terminal prioritizes data. When the terminal receives a first message indicating that the data capability of the first radio access network is unavailable, the terminal also implements steps S907 to S910 to prohibit the measurement of the channel quality of the cell under the first radio access network, or to measure the channel quality of the cell under the first radio access network but not to transmit the channel quality of the cell under the first radio access network, and not to reselect to a cell under the first radio access network. Optionally, the first message further indicates that the unavailability of the first radio access network is for a first duration. During the first duration, the terminal prohibits the measurement of the channel quality of the cell under the first radio access network, or to measure the channel quality of the cell under the first radio access network during the first duration but not to transmit the channel quality of the cell under the first radio access network, and not to reselect to a cell under the first radio access network during the first duration.

[0196] In other embodiments, when the terminal receives a first message indicating that the data and voice capabilities of the first radio access network are both unavailable, the terminal may skip step S904 and directly prohibit the measurement of the channel quality of the cell under the first radio access network, or measure the channel quality of the cell under the first radio access network but do not transmit the channel quality of the cell under the first radio access network and do not reselect to the cell under the first radio access network.

[0197] Similarly, optionally, the first message may also indicate that the unavailability period of the first radio access network is a first duration, during which the terminal is prohibited from measuring the channel quality of the cell under the first radio access network, or, during the first duration, it measures the channel quality of the cell under the first radio access network but does not transmit the channel quality of the cell under the first radio access network, and does not reselect to the cell under the first radio access network during the first duration.

[0198] Figure 10The demonstrated access indication method uses an example where the first message indicates that the voice capability of all radio access networks is unavailable for one day; however, this does not constitute a limitation on the content of the first message indication. Similarly, the example of a terminal initiating a UE attach procedure to LTE does not constitute a limitation on the objects to which the terminal executes the attach procedure. In the following text, LTE can be understood as network devices in the LTE system, such as access network devices and core network devices that support LTE; NR can be understood as network devices in the NR system, such as access network devices and core network devices that support 5G.

[0199] All radio access networks can be understood as radio access networks that can provide network services to terminals. There are multiple such networks. For example, all radio access networks may include Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN.

[0200] like Figure 10 As shown, the access indication method provided in this application embodiment includes:

[0201] S1001, The terminal sends a request message, and the corresponding LTE receives the request message.

[0202] For details on the request message, please refer to step S901; it will not be repeated here.

[0203] S1002, LTE sends and receives messages, and correspondingly, the terminal receives and receives messages.

[0204] For details on the message received, please refer to step S902; it will not be repeated here.

[0205] The received message includes a first message, which indicates the availability of capabilities of multiple radio access networks. Optionally, it can also indicate the duration for which a radio access network capability is unavailable, which may refer to voice and / or data capabilities. The multiple radio access networks include: Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN.

[0206] In Example 2, the first message indicates the availability of data capabilities for Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN, while voice capabilities are disabled for one day.

[0207] S1003. The terminal parses the first message to determine the availability and duration of unavailability of multiple wireless access network capabilities.

[0208] Upon receiving the acceptance message, the terminal retrieves the first message within it and parses it. This allows it to determine the availability and duration of unavailability of the capabilities of the multiple radio access networks indicated by the first message. In essence, the terminal can use the moment it receives the first message as a start time to determine that, from that start time, it cannot use the capabilities of the radio access networks during the specified unavailability period.

[0209] In Example 2 above, the terminal resolves that voice services from Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN will not be provided to the terminal for one day, while data services will be provided. Thus, the terminal can clearly use data services from Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN, but cannot use voice services from these providers for one day.

[0210] S1004. The terminal determines whether the user device is set to voice priority.

[0211] If the terminal determines that the user's device is set to voice priority, it can perform the following steps.

[0212] If the terminal determines that the user's device settings are not voice-first, it can perform the standard procedures after the terminal registers with the network. For details, please refer to the relevant protocol content, which will not be elaborated here.

[0213] S1005. The terminal sets the user equipment usage to data priority and starts the timer.

[0214] The terminal's user equipment (UE) is configured to prioritize voice. The first message indicates that voice services from Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN will not be provided to the terminal for one day. Understandably, the terminal will be unable to use the voice service of any radio access network for one day. To avoid the terminal continuously attempting to use voice services by downgrading the network standard, resulting in meaningless signaling interactions, while still unable to use the voice services of all radio access networks, the UE can be configured to prioritize data. This further ensures that the terminal enjoys high-quality data services.

[0215] Optionally, the first message indicates the duration for which the voice service is unavailable, based on which the terminal may also start a timer to keep track of the duration.

[0216] In some embodiments, the terminal's user equipment uses settings to make changes, and the terminal informs the network side of these changes. The following steps S1006 and S1007 are one way to implement the terminal informing the network side of its user equipment settings changes.

[0217] S1006, The terminal sends a request message, and the corresponding LTE receives the request message.

[0218] The request message includes information about the terminal's user equipment being set to prioritize data. Optionally, the request message can be a registration request message such as an attach request or a TAU request.

[0219] S1007, LTE sends and receives messages, and correspondingly, the terminal receives and receives messages.

[0220] The corresponding request message can be a registration acceptance message such as attach accept or TAU accept.

[0221] S1008a. The terminal is in connected state and reports the channel quality of the cell under NR.

[0222] Once the terminal establishes an RRC connection with LTE, the terminal is in connected mode. In connected mode, the terminal can measure the channel quality of surrounding serving cells and report the measurement results to the network side, facilitating a switch to a cell with better channel quality.

[0223] If the user equipment settings of the terminal are changed to data priority, the fact that the voice service of the radio access network indicated by the first message is not provided to the terminal for one day will not affect the terminal's use of data service. Therefore, the terminal measures the channel quality of the surrounding serving cells.

[0224] It is understandable that the terminal can measure and report the channel quality of cells under Sat-NG-RAN, Sat-E-UTRAN, NG-RAN, E-UTRAN, UTRAN, and GERAN to LTE. Typically, measuring cells under higher-level network standards ensures the terminal enjoys high-quality network services. Steps S1008a and S1009a below are illustrated using NG-RAN as an example, but this is not a limitation.

[0225] S1009a, Terminal access to a cell under NR.

[0226] In one application scenario, the terminal reports that the channel quality of the cell under NG-RAN is good, and the terminal can access the cell under NG-RAN under the action of the LTE handover command.

[0227] S1008b: The terminal is in an idle state; reselect the cell under NR.

[0228] The RRC connection between the terminal and LTE is released, and the terminal is in an idle state. The terminal can reselect the cell camp according to the network reselection policy.

[0229] Similarly, since the user equipment settings of the terminal are changed to data priority, the fact that the voice service of the radio access network indicated by the first message is not provided to the terminal for one day will not affect the terminal's use of data service. Therefore, the terminal can reselect to cells under various networks such as Sat-NG-RAN and NG-RAN.

[0230] In one application scenario, the terminal reselects to a cell under NG-RAN. Of course, this is just an example and does not constitute a limitation on cell reselection.

[0231] S1010: When the timer reaches one day, the terminal settings will prioritize voice for user equipment usage.

[0232] After the timer has run for the duration indicated by the first message that the capability is unavailable, the terminal can set the user equipment usage to voice priority. In Example 2, after the timer has run for one day, the terminal sets the user equipment usage to voice priority.

[0233] When a terminal changes its user equipment settings, it notifies the network side of this change. Steps S1011 and S1012 below are one way to implement the terminal informing the network side of the changes in its user equipment settings.

[0234] It is understandable that in some application scenarios, the terminal camps on a cell under the NR through step S1009a or step S1008b. Therefore, the following steps S1011 and S1012 are the interaction steps between the terminal and the NR, but this does not constitute a limitation.

[0235] In some embodiments, when the first message indicates that the durations of the unavailability of the capabilities of multiple radio access networks are not the same, the duration for which the terminal sets the user equipment to use data priority can be the duration of the unavailability of any one of the radio access networks, or alternatively, it can be the shortest duration among the unavailability durations of the capabilities of multiple radio access networks.

[0236] S1011, The terminal sends a request message, and the corresponding NR receives the request message.

[0237] The request message includes information that the user equipment of the terminal is set to voice priority. Optionally, the request message can be a registration request message such as an attach request or a TAU request.

[0238] S1012, NR sends and receives messages, and the corresponding terminal receives and receives the messages.

[0239] The corresponding request message can be a registration acceptance message such as attach accept or TAU accept.

[0240] It should be noted that, Figure 10 The demonstration also showcases a scenario where the terminal prioritizes voice input.

[0241] In some embodiments, the terminal prioritizes data. When the terminal receives a first message indicating that the data capabilities of multiple wireless access networks are unavailable, the terminal can set the user equipment usage to voice priority and notify the network of the change through steps S1006 to S1007. It can also execute steps S1008a to S1008b.

[0242] Optionally, the first message further indicates that the unavailability duration of multiple radio access networks is a first duration, and the duration for which the terminal sets the user equipment to prioritize data capability is a second duration, wherein the second duration is one of the first durations of the multiple radio access networks. Optionally, the duration for which the terminal sets the user equipment to prioritize data capability can be the shortest duration among the multiple first durations.
