Description

Wireless communication method, device, communication equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, but is not limited to the field of communications technologies, and in particular, to a wireless communication method, apparatus, communication device, and storage medium.

Background

The satellite access technology is one of the New air interface (NR) access technologies. When a terminal accesses a core network by using a satellite access technology, the terminal is affected by the satellite access type, the number of satellite deployments, the coverage of satellite beams and the like, and the problem of discontinuous coverage exists. That is, when a terminal uses non-geosynchronous satellite access, the current satellite signal covers the area where the terminal is located, and as the satellite moves relative to the earth, the satellite will move out of the signal coverage area of the terminal, thereby causing the satellite access of the terminal to be lost. And the signal coverage of the area where the terminal is located cannot be restored until the next satellite of the access network moves into the signal coverage area of the terminal.

In the related art, an extended discontinuous reception period (eDRX, enhanced Discontinuous Reception) is introduced. However, in the eDRX scenario without signal coverage, the terminal still cannot access the network, and how to further achieve the terminal power saving and/or reduce the probability of paging failure is a problem to be considered.

Execution bodies to which embodiments of the present disclosure relate include, but are not limited to: a terminal (UE) in a cellular mobile communication system, a base station for cellular mobile communication, and the like.

For a better understanding of the embodiments of the present disclosure, the following describes an application scenario of wireless communication:

In some application scenarios, the terminal accesses the network, and the power of the terminal is consumed when the service is developed. Limited by the terminal volume, power is often limited, especially for some internet of things terminals, its power supply is more limited. In order to be more efficient and to extend the power usage time as much as possible, some power saving mechanisms and power saving modes have been developed to save terminal power. For example, when the terminal is in a non-working state, the terminal is in a dormant state so as to save electric quantity. For example, in an area where the communication signal is not covered, the terminal continues to perform cell search and power consumption of the terminal increases, and thus in an area where the communication signal is not covered, it is desirable that the terminal does not perform cell search, network connection, or the like, in order to save the terminal power.

Referring to fig. 2, eDRX mechanisms have been developed in the communication technology for helping terminals save power. The eDRX related parameters are negotiated by the terminal and the access and mobility management function (AMF, access and Mobility Management Function), and mainly include eDRX period (cycle length) and paging time window (PTW, paging Time Window) parameters. In each eDRX cycle, there is one PTW, and the terminal listens to the paging channel in the PTW according to the DRX cycle (the DRX cycle time is short, and the terminal can be considered to be not dormant and can be reached all the time) so as to receive the downlink data, and the rest of the time is in a dormant state and does not receive the downlink data.

The eDRX mode may consider that the terminal device is reachable at any time, but the delay is larger, and the delay depends on eDRX cycle configuration, so that a balance between low power consumption and delay can be achieved.

The core network configures eDRX parameters to the UE through an initial registration or registration update procedure. In addition, the core network may also send the parameter to the gNB through a paging message, i.e. when the core network pages the UE, the eDRX parameter is also sent to the gNB.

eDRX parameters (e.g., period and PTW) are negotiated between a terminal and an AMF through a Non-Access Stratum (NAS). The related art defines a scenario for WB-E-UTRA and LTE-M connection 5GC, eDRX cycle values may be configured to 5.12s, 10.24s, 20.48s, etc., and maximum configuration values may be 2621.44s (approximately 44 minutes); for the NR connection 5GC scenario, eDRX cycle values may be configured to be 2.56s, 5.12s, 10.24s, 20.48s, etc., and the maximum configuration values may be 10485.76s (approximately 3 hours). For NR, PTW in eDRX needs to be greater than 10.24s. If the eDRX period is 2.56s or 5.12s, the network uses the paging strategy of DRX.

In one embodiment, the satellite access technology is one of the NR access technologies. When a terminal accesses 5GC using a satellite access technology, there is a problem of discontinuous coverage due to the influence of the satellite access type, the number of satellite deployments and the coverage of satellite beams, that is, when the terminal accesses using non-geosynchronous satellites (for example, low-orbit satellites, medium-orbit satellites and high-orbit satellites), the current satellite signal covers the area where the terminal is located, and as the satellite moves relative to the earth, the satellite moves out of the signal coverage area of the terminal, thereby causing the satellite access loss of the terminal until the next satellite of the access network moves into the signal coverage area of the terminal, so that the signal coverage of the terminal area is restored.

If a satellite access network is deployed with a smaller number of satellites, the time to form signal coverage for a particular area is shorter and the no signal coverage time is longer. For example, the time for which the signal coverage is provided for the area where the terminal is located is 20 minutes every 10 hours, that is, after the specified area is covered for 20 minutes, the coverage is required to be closed for 10 hours, and then the coverage is formed for 20 minutes.

Obviously, in the scene of satellite access discontinuous coverage, power saving technologies such as eDRX and the like are needed to be used for the terminal, so that actions such as continuously executing cell search when the terminal is not covered by satellite signals, trying network connection and the like are reduced, and the energy consumption of the terminal is saved.

Since the eDRX cycle in the related art is maximally configured to 3 hours, i.e., when more than 3 hours, the terminal enters the next eDRX cycle. According to the eDRX implementation technology, the terminal wakes up in the PTW of the next period, can execute network access, and sends uplink data and other operations. Similarly, when the terminal enters the next eDRX cycle, the network side will also attempt to page the terminal in the PTW of the cycle, send downlink data, etc. At this time, if the non-coverage time of the satellite access used by the terminal exceeds 3 hours (for example, 10 hours), the terminal is still in a non-signal coverage state, i.e. still unable to access the network, but the terminal initiates network access and performs operations such as cell search when the next eDRX cycle arrives. Therefore, in this scenario, the terminal power saving maximization is not achieved, and the probability of the network side paging terminal failure is increased.

As shown in fig. 3, in this embodiment, there is provided a wireless communication method, which is performed by a terminal, the method including:

step 31, determining an extended discontinuous reception eDRX parameter and an extended power saving time period (ePSL, extended Power Saving Length) parameter in response to a terminal through a satellite access network being in a discontinuous coverage area of a satellite signal;

wherein the eDRX parameters include a paging time window PTW and an eDRX period; the PTW is not greater than the duration of the coverage of the terminal by satellite signals; and the terminal is in a dormant state in the duration indicated by the ePSL parameter.

In one embodiment, the terminal is in a dormant state for a duration indicated by the ePSL parameter after the eDRX period.

Here, the terminal related to the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device, and/or a medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a predetermined version of a new air-interface NR terminal (e.g., an NR terminal of R17).

The network functions referred to in this disclosure may be various types of network functions, such as network functions of a fifth generation mobile communication (5G) network or other evolved network functions.

In order to better understand the technical solutions of the present disclosure, the following further describes the technical solutions of the present disclosure through 1 implementation routine embodiment:

example 1:

as shown in fig. 16, in this embodiment, there is provided a wireless communication method, which is performed by a network function, the method including:

step 161, the UE accesses the 5G network through a satellite. And the UE determines an eDRX parameter and an ePSL parameter according to the satellite coverage information, wherein PTW is set to be not more than satellite signal coverage duration, eDRX is set to be not less than PTW for not more than 3 hours, and ePSL is set to deduct the residual duration of the eDRX period from the satellite coverage period. For example, if the satellite provides 20 minutes of coverage every 10 hours, the PTW may be set to 655.36s (about 11 minutes), the eDRX period to 10485.76s (approximately 3 hours), and the ePSL to 7.2 hours, which may ensure that when the UE enters the next eDRX period after the ePSL timer expires, the UE is within satellite coverage, thereby ensuring that the UE may access the network or that the network may page the UE.

Step 162, the UE initiates a registration request to the network, where the request message includes eDRX parameters and ePSL parameters.

Step 163, the AMF determines eDRX and ePSL parameters according to the subscriber subscription information, the operator policy, and the terminal capability information. And determining parameters of a periodic registration update timer according to the eDRX parameter and the ePSL parameter, wherein the duration of the timer is not less than the sum of the eDRX period value and the ePSL value.

Step 164, the AMF returns a registration success message to the UE, where the message sends eDRX and ePSL parameters, and parameters of the registration update timer to the UE.

And step 165, after the registration is successful, the UE enters a connection state, and the UE can develop services and interact data with the network. The UE is about to enter an idle state for a certain period of time without data interaction. The connection between the UE and the RAN is released and the N2 connection between the RAN and the AMF is released.

Step 166, after the UE transitions to the idle state, it enters eDRX mode and starts the power saving mode. During the PTW time, the network may still initiate paging operations and the UE may still initiate uplink data. When the PTW times out, the UE is considered not to be within satellite coverage either, and a sleep mode is initiated. When eDRX expires, the UE remains in sleep mode according to ePSL. The network side still considers the UE to be in sleep mode according to the ePSL. When the ePSL expires, the UE wakes up, at which time it can be ensured that the UE is under satellite coverage. Specifically including 6a, 6b and 6c.

After the ePSL expires at step 167, the UE may send an SR request. Or initiates a registration update request based on expiration of a timer registration update timer. The network side may also send a paging message to the UE after the ePSL expires.

Therefore, through the scheme, the UE can be ensured to be always in a dormant state in a satellite coverage loss period, the purpose of saving electricity is realized, and the network side can not page the UE in the period. When the duration indicated by the ePSL parameter expires, the UE is ensured to be in satellite coverage, the UE may send a service request message or a registration update message, and the network side may page the UE. Therefore, the electricity saving maximization of the UE can be realized, and the probability of paging failure of the network side is reduced.
