Detailed Description

To facilitate an understanding of the present disclosure, some concepts related to the embodiments of the present disclosure are briefly described herein.

1. NTN (non-terrestrial/land network) communication is shown in fig. 1, for example.

The transmission mode and the reproduction mode can be classified according to the manner in which the satellite processes the signal. The transparent transmission mode is shown in fig. 2, where the NTN ground station transmits the base station signal to the satellite, and the satellite converts the signal to the satellite frequency band and transmits the signal to the terminal (also called terminal equipment) through the satellite frequency band, except for frequency conversion and signal amplification, the satellite does not demodulate the base station signal.

As shown in fig. 3, the NTN ground station transmits the base station signal to the satellite, and the satellite demodulates and decodes the signal, then re-encodes and modulates the signal, and transmits the regenerated signal through the satellite frequency band.

Table 1 below gives the satellite heights, orbits, satellite coverage of a typical NTN network:

TABLE 1

It will be appreciated that each element in table 1 is independent, and that these elements are illustratively listed in the same table, but do not represent that all elements in the table must exist simultaneously in accordance with what is shown in the table. Wherein the value of each element is independent of any other element value in table 1. It will be appreciated by those skilled in the art that the values of each of the elements in Table 1 are a separate embodiment.

2. Discontinuous reception (discontinuous reception, DRX): for internet of things service with infrequent data transmission, the data transmission is usually bursty, and when no data transmission exists, the power consumption can be reduced by closing a receiving circuit of the terminal equipment, so that the service time of a battery is prolonged. In each DRX period, the terminal equipment detects whether downlink service arrives once, wherein one DRX period is equal to the sum of the wake-up time of the terminal equipment and the sleep time of the terminal equipment, and the wake-up time of the terminal equipment is the time for the terminal equipment to monitor a paging channel, and in the period of time, the terminal equipment is in a wake-up state; the sleep time of the terminal device is the time that the terminal device enters sleep without monitoring the paging channel in order to save power, and during this time, the terminal device is in a sleep state. Due to the short DRX cycle, for example: the period may be 1.28s,2.56s,5.12s or 10.24s, and downlink traffic may be considered to be reachable at any time, so DRX is suitable for traffic with high requirements on delay, but the power consumption is relatively high.

3. Extended discontinuous reception (extended discontinuous reception, eDRX)

Depending on the number of satellites deployed, the coverage of the satellites may be discontinuous when the number of satellites is small, which means that the terminal device may be in and out of satellite coverage.

If the terminal device wishes to save its power consumption to a maximum, it may request eDRX to the mobility management entity (mobility management entity, MME) via a non-access stratum (nonaccess stratum, NAS) message (registration or tracking area update (tracking area update, TAU) procedure). The NAS message includes its preferred eDRX period. If accepted, the MME configures eDRX for the terminal device, transparent to the access network device. The eDRX configuration includes eDRX period (terx) and PTW (paging time window) length. When the MME sends the paging of the terminal device to the access network device, eDRX configuration will be provided together. The Core Network (CN) devices are configured with eDRX cycle lengths of 5.12s,10.24s, 10485.76s (i.e. 1024 superframe numbers (Hyper system Frame Number, hyper SFN), the radio access Network (radio access Network, RAN) only supports a maximum of 1024 Hyper SFNs, since the Hyper SFN broadcast in the system message is only 10 bits).

PTW is not applicable to RAN paging. The paging time window length for WB-S1 mode is 1.28 seconds, 2.56 seconds. The paging time window length for NB-S1 mode is 2.56 seconds. The PTW is terminal-specific and is determined by the paging superframe (paging hyperframe, PH), a start position (ptw_start) and an end position (ptw_end) within the PH. The PH is selected from one of the CN eDRX superframes based on the identity of the terminal device (ue_id), e.g. if CN edrx=20.56 s, there will be 2 superframes (20.56/10.24). The PH is further divided into 4 parts, each equal to 256 SFNs. Ptw_start is the start SFN of one of the parts. The portion is selected according to the ue_id.

The eDRX and the DRX have the same functions, and the purpose of saving battery consumption is achieved by periodically enabling the terminal device to enter a sleep state at certain moments. In an IoT system, the low rate and low frequency of the traffic require the terminal device to have extremely low power consumption, so as to further reduce the energy consumption of the terminal device, meet the extremely low power consumption requirement of the IoT device, introduce eDRX to cope with the traffic characteristics thereof, eDRX is an enhancement of DRX, support longer dormancy, and obviously reduce the power consumption of the terminal device. In each eDRX period, a plurality of DRX periods are included, the plurality of DRX periods form a paging time window (paging timewindow, PTW), the value of the paging time window determines the size of the window and the paging times, the terminal equipment monitors a paging channel in the PTW according to the DRX period (the DRX period time is short, the terminal can be considered to be not dormant and can be always reached), and the rest of the terminal equipment in the eDRX period is in a dormant state and does not receive downlink data.

Further, in order to facilitate understanding of the embodiments of the present disclosure, the following description is made.

First, in embodiments of the present disclosure, "for indicating" may include for direct indication and for indirect indication. When describing that a certain information is used to indicate a, it may be included that the information carries a, or it may also be included that the information indicates a directly or indirectly, and does not necessarily represent that a is carried in the information.

In the specific implementation process, the manner of indicating the information to be indicated is various, for example, but not limited to, the information to be indicated may be directly indicated, such as the information to be indicated itself or an index of the information to be indicated.

It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of the specific information may also be achieved by means of a pre-agreed (e.g., protocol-specified) arrangement sequence of the respective information, thereby reducing the indication overhead to some extent.

The information to be indicated can be sent together as a whole or can be divided into a plurality of pieces of sub-information to be sent separately, and the sending periods and/or sending occasions of the sub-information can be the same or different. The specific transmission method is not limited by the disclosure.
