Detailed ways

In order to facilitate understanding of the present disclosure, some concepts involved in the embodiments of the present disclosure are briefly introduced here.

1. NTN (non-terrestrialnetworks, non-terrestrial/terrestrial networks) communication method is shown in Figure 1.

According to the different ways in which satellites process signals, they can be divided into transparent transmission mode and regeneration mode. The transparent transmission mode is shown in Figure 2. The NTN ground station sends the base station signal to the satellite. The satellite converts the signal to the satellite frequency band and then sends it to the terminal (also called terminal equipment) through the satellite frequency band. In addition to frequency conversion and signal amplification, Satellites do not demodulate base station signals.

The regeneration mode is shown in Figure 3. After the NTN ground station sends the base station signal to the satellite, the satellite first demodulates and decodes the signal, then re-encodes and modulates it, and sends the regenerated signal through the satellite frequency band.

Table 1 below gives the satellite altitude, orbit, and satellite coverage of a typical NTN network:

Table 1

It can be understood that each element in Table 1 exists independently, and these elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element does not depend on the value of any other element in Table 1. Therefore, those skilled in the art can understand that the value of each element in Table 1 is an independent embodiment.

2. Discontinuous reception (DRX): For IoT services where data transmission is infrequent, data transmission is usually bursty. When there is no data transmission, power consumption can be reduced by turning off the receiving circuit of the terminal device. , thereby improving battery life. In each DRX cycle, the terminal device will detect whether downlink traffic arrives. One DRX cycle is equal to the sum of the terminal device wake-up time and the terminal device sleep time. The terminal device wake-up time is the time for the terminal device to monitor the paging channel. In During this period, the terminal device is in the awake state; the terminal device sleep time is the time when the terminal device enters sleep without monitoring the paging channel in order to save power. During this period, the terminal device is in the sleep state. Since the DRX cycle is short, for example, the cycle can be 1.28s, 2.56s, 5.12s or 10.24s, it can be considered that downlink services can be reached at any time. Therefore, DRX is suitable for services that have high requirements on latency, but the power consumption is relatively high. .

3. Extended discontinuous reception (eDRX)

Depending on the number of deployed satellites, when the number of satellites is small, satellite coverage may be discontinuous, which means that the terminal device may be within satellite coverage from time to time, and may be outside satellite coverage from time to time.

If the terminal device wishes to maximize its power consumption, it can request eDRX to the mobility management entity (mobility management entity) through a non-access stratum (NAS) message (registration or tracking area update (TAU) procedure) entity, MME). The NAS message includes its preferred eDRX period. If accepted, the MME will configure eDRX for the terminal device, transparently to the access network device. eDRX configuration includes eDRX period (TeDRX) and PTW (Paging Time Window) length. When the MME sends the paging of the terminal device to the access network device, the eDRX configuration will be provided together. The eDRX cycle length configured by the core network (Core Network, CN) equipment is 5.12s, 10.24s,..., 10485.76s (that is, 1024 super frame numbers (Hyper system Frame Number, Hyper SFN)), and the wireless access network ( radioaccess network (RAN) only supports a maximum of 1024 Hyper SFNs, because the Hyper SFN broadcast in the system message only has 10 bits).

PTW does not apply to RAN paging. The paging time window length of WB-S1 mode is 1.28 seconds, 2.56 seconds,...,20.48 seconds. The paging time window length of NB-S1 mode is 2.56 seconds,...,40.96 seconds. The PTW is specific to the terminal device and is determined by the paging hyperframe (PH), the start position (PTW_start) and the end position (PTW_end) within the PH. The PH is selected from one of the CN eDRX superframes based on the identification of the terminal equipment (UE_ID), for example, if CNeDRX=20.56s, there will be 2 superframes (20.56/10.24). PH is further divided into 4 parts, each part is equal to 256 SFN. PTW_start is the starting SFN of one of the sections. Select part based on UE_ID.

eDRX has the same function as DRX. They both achieve the purpose of saving battery consumption by allowing the terminal device to enter sleep state periodically at certain times. In the IoT system, the low speed and low frequency of services require terminal equipment to have extremely low power consumption. In order to further reduce the energy consumption of terminal equipment and meet the extremely low power consumption requirements of IoT equipment, eDRX was introduced to cope with its business characteristics. , eDRX is an enhancement to DRX, supports longer sleep, and significantly reduces the power consumption of terminal equipment. Each eDRX cycle contains several DRX cycles. Several DRX cycles form a paging time window (PTW). The value of the paging time window determines the size of the window and the number of paging. The terminal The device monitors the paging channel according to the DRX cycle within the PTW (the DRX cycle is short, it can be considered that the terminal does not sleep and is always reachable). During the rest of the eDRX cycle, the terminal device is in a sleep state and does not receive downlink data.

In addition, in order to facilitate understanding of the embodiments of the present disclosure, the following points are explained.

First, in the embodiment of the present disclosure, "used for indicating" may include used for direct indicating and used for indirect indicating. When describing certain information as indicating A, it may include that the information carries A, or it may also include that the information directly indicates A or indirectly indicates A, but it does not mean that the information must carry A.

The information indicated by the information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the information to be indicated.

The information to be instructed can be sent together as a whole, or can be divided into multiple sub-information and sent separately, and the sending period and/or sending timing of these sub-information can be the same or different. This disclosure does not limit the specific sending method. The sending period and/or sending timing of these sub-information may be predefined, for example, according to a protocol.

Second, in the embodiments shown below, the first, second and various numerical numbers (such as the first indication information, the second indication information) are only used for the convenience of description and are not used to limit the embodiments of the present disclosure. scope.

Fourth, “at least one” refers to one or more, and “multiple” refers to two or more. "And/or" describes the association of associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A, B can be singular or plural.

In the related technology, as shown in Figure 5, when the core network device configures eDRX parameters for the terminal device, it only configures the eDRX cycle and the length of the PTW, but does not configure the starting position of the PTW. The starting position of the PTW is calculated based on the identification (ID) of the terminal device. The starting position of the PTW calculated by the terminal device may be at any position within the eDRX cycle. However, in a discontinuous coverage scenario, it is difficult to guarantee that the PTW of eDRX falls within the covered time period. This is an urgent problem that needs to be solved.
