Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0124] The embodiments of this disclosure are applicable to non-terrestrial networks (NTNs), which may include networks or network segments that use airborne or space-based vehicles to carry transmission equipment relay nodes or base stations, and may also include any network involving non-terrestrial flying objects. For example, an NTN may include a satellite communication network, high altitude platform systems (HAPs), etc. In this disclosure, a satellite communication network is used as an example of an NTN for illustration.
[0125] With the development of communication technology, satellite communication technology is considered an important aspect of future wireless communication technology development. Communication systems that support satellite access technology (such as 4G and 5G networks) can also be called satellite communication networks. In this communication network, terminals can access the core network (such as EPC and 5GC) and conduct business through the satellite access network. However, due to insufficient satellite deployment, satellite access networks may experience limited coverage, and therefore, satellites may not be able to provide continuous connection services. This discontinuous satellite connection includes situations where the service connection between the satellite and the terminal or the feeder connection between the satellite and the ground station is interrupted.
[0126] In some embodiments, the connection between the satellite and the terminal may also be referred to as a service link, and the connection between the satellite and the ground station may also be referred to as a feeder link.
[0127] In some embodiments, the satellite communication network can have two different architectures. These two architectures are a satellite communication network architecture based on transparent payloads (i.e., transparent mode) and a satellite communication network architecture based on regenerative payloads (i.e., regenerative mode).
[0128] In some embodiments, as shown in FIG1B, FIG1B is a schematic diagram of a satellite communication system architecture based on a transparent payload according to an embodiment of the present disclosure. In this satellite communication system architecture, the core network is described as 5GC. Of course, the core network can also be other evolved versions of the core network, and the embodiments of the present disclosure do not specifically limit this. In transparent mode, gNB 20 is deployed on the ground, and satellite 10 implements the radio frequency function of gNB 20. The ground station sends the signal of gNB 20 to satellite 10. Satellite 10 converts the signal to the satellite frequency band and then transmits it to the terminal through the satellite frequency band. Except for frequency conversion and signal amplification, satellite 10 does not demodulate the signal of gNB 20. The role of satellite 10 is equivalent to a repeater.
[0129] In some embodiments, as shown in FIG1C, FIG1C is a schematic diagram of a satellite communication system architecture based on a regenerative payload according to an embodiment of the present disclosure. In this satellite communication system architecture, the core network is still described as 5GC. Of course, the core network can also be other evolved versions of the core network, and the embodiments of the present disclosure do not specifically limit this. In regenerative mode, gNB 20 is deployed on satellite 10. At this time, gNB can be referred to as onboard gNB. After the ground station sends the signal to the satellite, satellite 10 demodulates and decodes the signal and then re-encodes and modulates it (this process can be called regeneration) and sends the regenerated signal to the terminal through the satellite frequency band.
[0130] In some embodiments, the operating mode of the satellite communication system based on the above-described transparent transmission mode or regeneration mode can be described as normal or default satellite operation.
[0131] In some embodiments, to provide latency-tolerant communication services, satellite communication systems support store-and-forward (S&F) functionality. Store-and-forward (S&F) satellite operation is an operating mode for communication systems with satellite access (i.e., satellite communication systems). When satellite connectivity is intermittent or temporarily unavailable, the communication system can provide a certain level of service (such as storing and forwarding data). For example, it can provide communication services to terminals within satellite coverage without simultaneously connecting to a ground-based feeder link.
[0132] In some embodiments, S&F satellite operation is a commonly used data transmission method in satellite communications, suitable for scenarios where real-time communication is not possible or the communication link is unstable. In some embodiments, S&F satellite operation can be applied in fields such as ocean monitoring, environmental monitoring, telemedicine, and disaster response, enabling effective data transmission even in the absence of a stable real-time communication link.
[0133] Under S&F satellite operation, data transmission typically includes at least one of the following steps:
[0134] Step 1, Terminal uplink data transmission: First, the terminal sends data to the satellite. If there is no connection between the satellite and the ground station (e.g., gateway) (e.g., no feeder link), the satellite stores the data. Then, if there is a connection between the satellite and the ground station (e.g., feeder link exists), the satellite forwards the data to the ground station. Finally, the ground station receives the data sent by the terminal.
[0135] Step 2: Terminal receives downlink data: First, if the ground station is not connected to the satellite (e.g., without feederlink), the ground station (e.g., S-GW or MME) buffers the data. Then, if the ground station establishes a connection with the satellite (e.g., feederlink), the ground station sends the data to the satellite. If the satellite establishes a connection with the terminal, the satellite sends the data to the terminal. If the satellite does not establish a connection with the terminal, the satellite buffers the data until a connection is established, at which point the satellite sends the data to the terminal. Finally, the terminal receives the data sent by the ground station.
[0136] In some embodiments, S&F satellite operation has the following advantages: it can overcome geographical limitations, i.e., since the satellite can cover any place on Earth, it can enable communication in remote areas or for mobile targets; it can cope with unstable communication links, i.e., in the event of an unstable or unavailable communication link, data can be temporarily stored on the satellite and transmitted when the link is restored; and it can enable batch transmission of data, i.e., the satellite can collect a large amount of data and transmit it all at once, which can improve communication efficiency.
[0137] In some embodiments, as shown in FIG2A, FIG2A is a schematic diagram illustrating normal or default satellite operation according to an embodiment of the present disclosure. In the "normal / default satellite operation" mode, the interaction of signaling and data transmission between the terminal and the remote terrestrial network (TN) via the satellite requires the simultaneous activity of the serving link and the feeder link. Therefore, when the terminal interacts with the satellite via the serving link, there is a continuous, end-to-end connection path between the terminal, the satellite, and the terrestrial network.
[0138] In some embodiments, as shown in FIG2B, FIG2B is a schematic diagram illustrating a store-and-forward satellite operation according to an embodiment of the present disclosure. In contrast to the normal satellite operation described above, under S&F satellite operation, the interaction of end-to-end signaling or data transmission is processed as a combination of two steps that are not performed simultaneously (steps A and B in FIG2B). In step A, signaling or data transmission occurs between the terminal and the satellite, at which time the satellite may not be connected to the terrestrial network (i.e., the satellite can use the service link even without an available feeder link connection). In step B, a connection is established between the satellite and the terrestrial network (i.e., a feeder link is established), enabling communication between the satellite and the terrestrial network. Therefore, the satellite moves from connecting to the terminal in step A to connecting to the terrestrial network in step B.
[0139] In some embodiments, support for S&F satellite operations is particularly applicable to providing latency-tolerant or non-real-time IoT satellite services for non-geostationary satellite orbit (NGSO) satellites.
[0140] The terminology used in the embodiments of this disclosure will now be explained and interpreted.
[0141] I. Introduction to Measurement of Neighboring Communities
[0142] If t-Service exists in the serving cell's system information (such as SystemInformationBlockType3), the terminal should perform intra-frequency, inter-frequency, or inter-system (inter-RAT) measurements before time t-Service, regardless of whether the serving cell satisfies Srxlev>S. IntraSearchP And Squal>S IntraSearchQ , or Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ The exact time before t-Service begins measurement can depend on the terminal implementation. If t-ServiceStartNeigh exists in system information (such as SystemInformationBlockType33), it can be used to determine when to start measurement. The terminal should perform higher-priority inter-frequency or inter-system measurements, regardless of the remaining service time of the serving cell.
[0143] Where Srxlev is the received power of the serving cell; Squal is the received signal quality of the serving cell; S IntraSearchP S represents the Srxlev threshold for same-frequency measurements; S IntraSearchQ Squal represents the threshold for same-frequency measurements; S nonIntraSearchP This represents the Srxlev threshold for inter-frequency and inter-system measurements on access network equipment; S nonIntraSearchQ This represents the Squal threshold for inter-frequency and inter-system measurements of access network equipment.
[0144] In some embodiments, neighbor cell measurement may include at least one of the following: intra-frequency cell measurement, inter-frequency cell measurement, inter-system cell measurement, intra-frequency measurement, inter-frequency measurement, and inter-system measurement performed by a radio resource control (RRC) idle-state terminal. In some embodiments, neighbor cell measurement may include at least one of the following: intra-frequency cell measurement, inter-frequency cell measurement, inter-system cell measurement, intra-frequency measurement, inter-frequency measurement, and inter-system measurement performed by an RRC inactive-state terminal.
[0145] In some embodiments, terms such as "co-frequency cell measurement", "co-frequency measurement", and "co-frequency measurement of neighboring cells" can be used interchangeably.
[0146] In some embodiments, terms such as "inter-frequency cell measurement", "inter-frequency measurement", and "inter-frequency measurement of neighboring cells" can be used interchangeably.
[0147] In some embodiments, terms such as "inter-system cell measurement", "inter-system measurement", and "inter-system measurement of neighboring cells" can be used interchangeably.
[0148] In some embodiments, "neighbor cell measurement" and "measure neighbor cells" can be used interchangeably.
[0149] II. Introduction to t-Service
[0150] t-Service indicates the time information when the serving cell provided by the NTN system will cease providing service to its currently covered area; that is, the time during which the serving cell provides service to the terminal. This field applies to service link transitions in the NTN quasi-Earth fixed system and feeder link transitions in the NTN quasi-Earth fixed and Earth moving system.
[0151] For the aforementioned satellite access regenerative architecture, the gNB function is deployed on the satellite. Even in the event of discontinuous satellite connections, latency-tolerant services can still be provided. This requires the satellite to support data storage and forwarding capabilities, so that data can be stored on the satellite in the event of a satellite connection interruption and forwarded when the satellite connection is restored. However, even when both the satellite and the terminal support storage and forwarding capabilities, whether to perform measurements on neighboring cells is a problem that urgently needs to be solved.
[0152] To address the aforementioned issues, embodiments of this disclosure provide a communication method, communication device, terminal, access network equipment, and storage medium that can determine whether to measure neighboring cells, thereby avoiding unnecessary measurements by the terminal and saving power consumption.
[0153] In this embodiment of the disclosure, the access network device can be deployed on a satellite, and in this case, the access network device can be described as a satellite-borne access network device.

[0212] In some embodiments, when the terminal receives the first information and time information, and the signal quality of the serving cell is greater than the first value, it determines not to measure neighboring cells before the time indicated by the time information. This can be divided into the following two cases:
[0213] Case 1: If the terminal receives the first information and time information and the first parameter is greater than the first threshold value, it determines not to measure neighboring cells before the time indicated by the time information.
[0214] Scenario 2: When the terminal receives the first information and time information, and the first parameter is greater than the first threshold value and the second parameter is greater than the second threshold value, it determines not to measure neighboring cells before the time indicated by the time information.
[0215] In one example, case 1 could include: the terminal receives the first information and the time information, and Srxlev > S IntraSearchP In such cases, before the time indicated by the time information, it is determined not to perform co-frequency measurements on neighboring cells.
[0216] In one example, case 1 could include: the terminal receives the first information and the time information, and Srxlev > S nonIntraSearchP In the case of this, before the time indicated by the time information, it is determined not to perform inter-frequency measurements on neighboring cells.
[0217] In one example, case 1 could include: the terminal receives the first information and the time information, and Srxlev > S nonIntraSearchP In such cases, before the time indicated by the time information, it is determined not to perform inter-system measurements on neighboring cells.

As shown in Figure 5B, the present disclosure relates to a communication method applied to the aforementioned access network device, and the method includes step S5201.
[0370] In step S5201, the first information is sent.
[0371] The optional implementation of step S5201 can be found in Figure 3A, Figure 3B, and other related parts in the embodiments involved in Figures 3A and 3B, which will not be repeated here.
[0372] In some embodiments, if the UE supports store and forward, and the serving cell has store and forward enabled, the UE determines whether to measure neighboring cells based on the signal quality of the serving cell.
[0373] In some embodiments, if the UE supports store and forward function and the serving cell has store and forward function enabled, and if the network is configured with time information for neighbor cell measurement, the UE ignores the time information and determines whether to measure neighbor cells based on the signal quality of the serving cell.
[0374] In some embodiments, the time information is t-service, which includes service link switching in the NTN quasi-geo-fixed system and feeder link switching in the NTN quasi-geo-fixed and geomobile systems.
[0375] In some embodiments, the time information is the time of switching the feeder link (such as a feeder link switch).
[0376] In some embodiments, neighbor cell measurement includes same-frequency measurement, different-frequency measurement, and different-system measurement.
[0377] In some embodiments, if the UE supports store and forward, and the serving cell has store and forward enabled, if the network is configured with time information for neighbor cell measurements, and if the signal quality of the serving cell is higher than a threshold, the UE may choose not to perform neighbor cell measurements.
[0378] In some embodiments, if the UE supports store and forward, and the serving cell has store and forward enabled, if the network is configured with time information for neighbor cell measurements, and if the signal quality of the serving cell is below a threshold, the UE should perform neighbor cell measurements before the time information is available.
[0379] In one example, if the measurement is performed using a specified received signal strength (RSS), and the serving cell satisfies Srxlev > S IntraSearchP If the time information is stored in the system information, and the UE supports store-and-forward functionality, and the serving cell has store-and-forward functionality enabled, the UE can choose not to perform in-frequency measurements. If the UE does not support store-and-forward functionality, and / or the serving cell has not enabled store-and-forward functionality, regardless of whether the serving cell satisfies Srxlev>S IntraSearchP The UE should perform co-frequency measurement before the time information; if the time information is not available in the system information, the UE can choose not to perform co-frequency measurement.
[0380] In one example, if the serving cell satisfies Srxlev>S IntraSearchP And Squal>S IntraSearchQIf the time information is stored in the system information, and the UE supports store-and-forward functionality, and the serving cell has store-and-forward functionality enabled, the UE can choose not to perform in-frequency measurements. If the UE does not support store-and-forward functionality, and / or the serving cell has not enabled store-and-forward functionality, regardless of whether the serving cell satisfies Srxlev>S IntraSearchP And Squal>S IntraSearchQ The UE should perform co-frequency measurement before the time information is available; if the time information is not available in the system information, the UE may choose not to perform co-frequency measurement.
[0381] In one example, if the measurement is performed using the specified RSS, and the serving cell satisfies Srxlev>S nonIntraSearchP Time information is contained in the system information. If the UE supports store-and-forward functionality and the serving cell has store-and-forward functionality enabled, the UE can choose not to perform inter-frequency measurements and / or inter-system measurements. If the UE does not support store-and-forward functionality, and / or the serving cell has not enabled store-and-forward functionality, regardless of whether the serving cell satisfies Srxlev>S nonIntraSearchP The UE should perform inter-frequency measurements and / or inter-system measurements before the time information; if the time information is not present in the system information, the UE may choose not to perform inter-frequency measurements and / or inter-system measurements.
[0382] In one example, if the serving cell satisfies Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ Time information is contained in the system information. If the UE supports store-and-forward functionality and the serving cell has store-and-forward functionality enabled, the UE can choose not to perform inter-frequency measurements and / or inter-system measurements. If the UE does not support store-and-forward functionality, and / or the serving cell has not enabled store-and-forward functionality, regardless of whether the serving cell satisfies Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ The UE should perform inter-frequency measurements and / or inter-system measurements before the time information; if the time information is not present in the system information, the UE may choose not to perform inter-frequency measurements and / or inter-system measurements.
