Description

Radio Resource Control (RRC) state switching method, device, user equipment, base station and storage medium

Technical Field

The disclosure relates to the field of communication technologies, and in particular, to a radio resource control RRC state handover measurement method, a device, a user equipment, a base station, and a storage medium.

Background

In the 5G communication system, satellite communication technology is an important aspect of future development, but is limited by the number of satellites or the movement track of the satellites, so that the satellites cannot achieve all-weather coverage. Based on this, in order to save power consumption of a UE (User Equipment), when the UE is not in satellite coverage, the UE is generally configured not to receive downlink signaling or transmit uplink signaling.

In the related art, the base station generally periodically configures DRX (Discontinuous Reception ) for the UE so that the UE does not perform reception of downlink signaling or transmission of uplink signaling for a short time. However, the period of DRX in the related art is short (for example, typically several tens of milliseconds), and the time that the UE is not in satellite coverage in satellite communication is long (for example, typically several hours), so that the manner of configuring DRX in the related art cannot be applied to the satellite communication system, and therefore a UE power saving method applicable to the satellite communication system is needed.

The following describes in detail a radio resource control RRC (Radio Resource Control ) state switching method, apparatus, user equipment, base station, and storage medium provided in embodiments of the present disclosure with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a radio resource control RRC state switching method provided in an embodiment of the present disclosure, where the method is performed by a UE, and as shown in fig. 1, the radio resource control RRC state switching method may include the following steps:

step 101, receiving RRC state indication information sent by the base station, where the RRC state indication information includes a target RRC state and/or a service start time of a satellite for a next service of the UE.

It should be noted that, the RRC state switching method according to the embodiments of the present disclosure may be applied to any UE. A UE may be a device that provides voice and/or data connectivity to a user. The UE may communicate with one or more core networks via a RAN (Radio Access Network ), which may be an internet of things terminal such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things terminal, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile), remote Station (remote Station), access point, remote terminal (remote), access terminal (access terminal), user device (user terminal), or user agent (user agent). Alternatively, the UE may be a device of an unmanned aerial vehicle. Alternatively, the UE may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless terminal externally connected to the laptop. Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

In one embodiment of the present disclosure, a method of receiving RRC state indication information transmitted by a base station may include at least one of:

receiving RRC state indication information sent by a base station through a high-layer signaling;

and receiving RRC state indication information sent by the base station through physical layer signaling.

Among other things, in one embodiment of the present disclosure, the above-described higher layer signaling may include at least one of:

RRC signaling;

MAC CE (Media Access Control Address Control Element, medium access control layer control element) signaling.

And, in one embodiment of the present disclosure, the above-mentioned physical layer signaling may include DCI (Downlink Control Information ) signaling. Further, in one embodiment of the present disclosure, when the state of the terminal and/or the corresponding time information is notified through the physical layer signaling, the RRC state indication information may be transmitted over a certain information domain of the DCI signaling when the above information is transmitted using the DCI signaling. In one embodiment of the present disclosure, the information field carrying RRC state indication information may be a fixed information field in DCI signaling. In another embodiment of the present disclosure, the information field carrying RRC state indication information may be a configurable information field, and by way of example, may be an information field configured by a base station. And, in one embodiment of the present disclosure, the length of the information field carrying RRC state indication information may be fixed. In one embodiment of the present disclosure, the length of the information field carrying the RRC state indication information may be configurable (e.g., may be configured by the base station).

In one embodiment of the present disclosure, the service start time of the next service of the satellite to the UE may include at least one of:

the service start time of the current service satellite for the next service of the UE;

the other service satellites start time for the next service of the UE.

It should be noted that, in one embodiment of the present disclosure, the RRC state indication information may be specifically sent to the UE by the base station when it is determined that the service end time of the current service satellite is about to arrive.

And, in one embodiment of the present disclosure, the above-mentioned RRC state indication information may include only the target RRC state. Wherein the target RRC state may be an RRC non-connected state. Specifically, in one embodiment of the present disclosure, the target RRC state may be a first predefined RRC state or a second predefined RRC state. And whether the target RRC state in the RRC state indication information received by the UE is specifically the first predefined RRC state or the second predefined RRC state is determined by the base station based on an interval value between a service end time of the currently serving satellite and a service start time of the next service.

Specifically, in one embodiment of the present disclosure, the base station may first determine a service end time of a current service satellite of the UE and a service start time of the satellite for a next service of the UE; then, if the current time arrives at the service end time and the interval value between the service end time and the service start time of the next service is greater than a first threshold value (that is, the time that the satellite does not provide service for the UE is longer), the target RRC state in the RRC state indication information sent by the base station to the UE may be a first predefined RRC state, where in the first predefined RRC state, the UE may not send and receive signaling with the base station for a longer time. If the current time arrives at the service end time and the interval value between the service end time and the service start time of the next service is less than or equal to a second threshold value (i.e. the time that the satellite does not provide service for the UE is shorter), the target RRC state in the RRC state indication information sent by the base station to the UE may be a second predefined RRC state, where in the second predefined RRC state, the UE may not send and receive signaling with the base station in a shorter time.

Among other things, in one embodiment of the present disclosure, the base station may specifically determine a service end time of a currently serviced satellite and a service start time of a next service based on ephemeris information of the satellite.

And, in one embodiment of the present disclosure, the first threshold value may be greater than or equal to the second threshold value.

Further, in another embodiment of the present disclosure, the RRC state indicating information described above may include only a service start time of a next service of the satellite to the UE. Based on this, the UE, after receiving the RRC state indication information, may determine a target RRC state to which it is to be handed over based on an interval value between a current time and a service start time of a next service of the UE.

Specifically, in one embodiment of the present disclosure, if the interval value between the current time and the service start time of the next service is greater than a first threshold value (i.e., the time during which the satellite does not provide the service to the UE is longer), the UE may determine that the target RRC state to be switched is a first predefined RRC state, where the UE may not send and receive signaling with the base station for a longer time in the first predefined RRC state. If the interval value between the current time and the service start time of the next service is less than or equal to the second threshold value (i.e. the time that the satellite does not provide service for the UE is shorter), the UE may determine that the target RRC state to be switched is the second predefined RRC state, where in the second predefined RRC state, the UE may not send and receive signaling with the base station in a shorter time.

In still another embodiment of the present disclosure, the RRC state indicating information may include a target RRC state and a service start time of a satellite for a next service of the UE.

Step 102, switching to the target RRC state based on the RRC state indication information.

In one embodiment of the present disclosure, after determining the target RRC state based on the RRC state indication information (the process of determining the target RRC state may be described with reference to the above), the UE may switch to the target RRC state and perform an operation corresponding to the target RRC state on the target RRC state.

Among other things, in one embodiment of the present disclosure, at least one of the following operations may be specifically performed when the UE switches to the first predefined RRC state:

the UE shuts down all hardware modules for cellular communication (e.g., shuts down all cellular modules);

the UE does not perform DRX (Discontinuous Reception );

the UE stops detecting paging information;

the UE stops acquiring the system information;

the UE does not perform neighbor cell measurement operations.

That is, in one embodiment of the present disclosure, the UE may not communicate with the base station for a long time in the first predefined RRC state.

As can be seen from the foregoing, in one embodiment of the present disclosure, when the target RRC state is the first predefined RRC state, it is indicated that the interval value between the service end time of the currently served satellite and the service start time of the next service is greater than the first threshold value (i.e., the time during which the satellite does not provide service for the UE is longer), and at this time, the UE may switch to the first predefined RRC state to implement long-time communication without the base station, so as to avoid the UE from performing an invalid operation and save power consumption of the UE.

In another embodiment of the present disclosure, when the target RRC state is the second predefined RRC state, the UE may specifically perform the following operations when switching to the second predefined RRC state: the UE performs DRX.

Specifically, in one embodiment of the present disclosure, a method for a UE to perform DRX may include: receiving first configuration information sent by a base station, wherein the first configuration information comprises indication information of parameters when UE executes DRX; the first configuration information is specifically determined by the base station based on the service starting time of the next service; and then, the UE executes DRX operation according to the indication of the first configuration information.

It follows that in one embodiment of the present disclosure, the UE may not communicate with the base station for a short time in the second predefined RRC state.

As can be seen from the foregoing, in one embodiment of the present disclosure, when the target RRC state is the second predefined RRC state, it is indicated that the interval value between the service end time of the currently served satellite and the service start time of the next service is less than or equal to the second threshold value (i.e., the time that the satellite does not provide service for the UE is shorter), and at this time, the UE may switch to the second predefined RRC state to implement that communication with the base station is not performed in a short time, so that the UE may be prevented from performing an invalid operation and power consumption of the UE may be saved.

Fig. 2 is a flowchart of a radio resource control RRC state switching method provided in an embodiment of the present disclosure, where the method is performed by a UE, and as shown in fig. 2, the radio resource control RRC state switching method may include the following steps:

Step 201, receiving RRC state indication information sent by a base station, where the RRC state indication information includes a first predefined RRC state and/or a service start time of a satellite for a next service of the UE.

Wherein, in one embodiment of the present disclosure, the RRC state indicating information in step 201 may include only the first predefined RRC state.

In another embodiment of the present disclosure, the RRC state indicating information in step 201 may include only a service start time of the next service of the satellite to the UE. Wherein, in one embodiment of the present disclosure, the interval value between the current time and the service start time of the next service of the satellite to the UE should be greater than the first threshold value.

In yet another embodiment of the present disclosure, the RRC state indication information in step 201 may include a first predefined RRC state and a service start time of a satellite for a next service of the UE.

Step 202, switching to a first predefined RRC state based on the RRC state indication information.

The detailed descriptions of steps 201-202 may be described with reference to the above embodiments, and the embodiments of the disclosure are not repeated herein.

Fig. 3 is a flowchart illustrating a radio resource control RRC state switching procedure according to an embodiment of the present disclosure, where the method is performed by a UE, and as shown in fig. 3, the radio resource control RRC state switching method may include the following steps:

step 301, receiving RRC state indication information sent by the base station, where the RRC state indication information includes a second predefined RRC state and/or a service start time of a satellite for a next service of the UE.

Wherein, in one embodiment of the present disclosure, the RRC state indicating information in step 301 may include only the second predefined RRC state.

In another embodiment of the present disclosure, the RRC state indicating information in step 301 may include only a service start time of the next service of the satellite to the UE. Wherein, in one embodiment of the present disclosure, an interval value between a current time and a service start time of a next service of the satellite to the UE should be less than or equal to a second threshold value.

In yet another embodiment of the present disclosure, the RRC state indication information in step 301 may include a second predefined RRC state and a service start time of the satellite for a next service of the UE.

Step 302, switching to a second predefined RRC state based on the RRC state indication information.

In summary, the UE receives RRC state indication information sent by the base station, where the RRC state indication information includes a target RRC state and/or a service start time of a satellite for a next service of the UE, and then the UE switches to the target RRC state based on the RRC state indication information. In the embodiment of the present disclosure, the target RRC state in the RRC state indication information is specifically determined by the base station based on an interval value between a service end time of a currently serving satellite of the UE and a service start time of a next service of the satellite to the UE, and in the embodiment of the present disclosure, the target RRC state is specifically an RRC non-connected state. It can be seen that in the embodiments of the present disclosure, the UE is determined to be switched to the RRC non-connected state based on the interval value between the service end time of the current service satellite and the service start time of the next service, so as to avoid the situation that the UE performs data transmission and reception when the satellite does not provide the service (i.e., when the satellite is not covered), avoid the invalid operation of the UE, and save the power consumption.

Fig. 4 is a flowchart of a radio resource control RRC state switching method provided in an embodiment of the present disclosure, where the method is performed by a UE, and as shown in fig. 4, the radio resource control RRC state switching method may include the following steps:

Step 401, receiving RRC state indication information sent by a base station, where the RRC state indication information includes a target RRC state and/or a service start time of a satellite for a next service of the UE.

Step 402, switching to the target RRC state based on the RRC state indication information.

The detailed descriptions of steps 401-402 may be described with reference to the above embodiments, and the embodiments of the disclosure are not repeated herein.

Step 403, receiving second configuration information sent by the base station.

In one embodiment of the present disclosure, the second configuration information may specifically be used to instruct the UE to switch from the target RRC state (i.e. RRC non-connected state) back to the RRC connected state, so as to communicate with the base station normally.

Specifically, the method for the base station to send the second configuration information mainly comprises the following steps: if the current time reaches the service start time of the next service (i.e. when the satellite is about to provide the service for the UE), the base station may send second configuration information to the UE to instruct the UE to switch back to the RRC connected state, so as to ensure normal communication between the UE and the base station during the period when the satellite provides the service for the UE.

Wherein, in one embodiment of the present disclosure, the second configuration information may include at least one of:

Service beam information of a target service satellite for providing service next time;

the resource allocation information when performing random access (e.g., may be a random access signal characteristic and/or a time-frequency resource location where the random access signal is located);

and the time-frequency resource corresponding to the UE.

Step 404, performing random access based on the configuration information to switch to the RRC connected state.

Fig. 5 is a flowchart of a radio resource control RRC state switching method according to an embodiment of the present disclosure, where the method is performed by a base station, and as shown in fig. 5, the radio resource control RRC state switching method may include the following steps:

step 501, determining the service end time of the current service satellite of the UE and the service start time of the satellite for the next service of the UE.

In one embodiment of the present disclosure, the base station may specifically determine a service end time of a currently serving satellite and a service start time of a next service of the satellite to the UE based on the ephemeris information.

And, in one embodiment of the present disclosure, the method of the base station transmitting RRC state indication information to the UE may include at least one of:

transmitting RRC state indication information to the UE through a high-layer signaling;

and sending RRC state indication information to the UE through physical layer signaling.

the signaling of the RRC is performed,

MAC CE signaling

And, in one embodiment of the present disclosure, the physical layer signaling described above may include DCI signaling. Further, in one embodiment of the present disclosure, when the RRC state indicating information is transmitted using DCI signaling, the RRC state indicating information may be transmitted over a certain information field of the DCI signaling. In one embodiment of the present disclosure, the information field carrying RRC state indication information may be a fixed information field in DCI signaling. In another embodiment of the present disclosure, the information field carrying RRC state indication information may be a configurable information field, and by way of example, may be an information field configured by a base station. And, in one embodiment of the present disclosure, the length of the information field carrying RRC state indication information may be fixed. In one embodiment of the present disclosure, the length of the information field carrying the RRC state indication information may be configurable (e.g., may be configured by the base station).

In one embodiment of the present disclosure, the service start time of the next service of the satellite to the UE includes at least one of:

the other service satellites start time for the next service of the UE.

Step 502, sending RRC state indication information to the UE, where the RRC state indication information includes a target RRC state and/or a service start time of a next service, and the RRC state indication information is used to indicate the UE to switch to the target RRC state.

Among other things, in one embodiment of the present disclosure, the RRC state indication information may include only the target RRC state.

And, in one embodiment of the present disclosure, when the RRC state indicating information may include a target RRC state, the base station transmits the state indicating information to the UE, specifically, based on an interval value between a service end time of a current service satellite and a service start time of a next service.

Specifically, in one embodiment of the present disclosure, if the current time arrives at the service end time (e.g., the interval value between the current time and the service end time is smaller than the first threshold value), and the interval value between the service end time and the service start time of the next service is greater than the first threshold value (i.e., the time that the satellite does not provide service to the UE is longer), the target RRC state in the RRC state indication information sent by the base station to the UE may be a first predefined RRC state, where the UE may not send and receive signaling with the base station for a longer time in the first predefined RRC state.

In another embodiment of the present disclosure, if the current time arrives at the service end time and the interval value between the service end time and the service start time of the next service is less than or equal to the second threshold (i.e. the time that the satellite does not provide service for the UE is shorter), the target RRC state in the RRC state indication information sent by the base station to the UE may be a second predefined RRC state, where in the second predefined RRC state, the UE may not send and receive signaling with the base station in a shorter time.

In another embodiment of the present disclosure, the RRC state indication information may include only a service start time of the next service of the satellite to the UE.

It should be noted that, in one embodiment of the present disclosure, when the RRC state indicating information includes a service start time of a next service of the satellite to the UE, the base station specifically sends, to the UE, RRC state indicating information including only the service start time of the next service of the satellite to the UE when determining that the current time reaches the service end time, so that the UE can determine that it will switch the target RRC state based on the service start time of the next service of the satellite to the UE.

And, in still another embodiment of the present disclosure, the RRC state indication information may include a target RRC state and a service start time of a satellite for a next service of the UE, and the UE may determine that it is to switch the target RRC state based on the RRC state information.

Further, in one embodiment of the present disclosure, when the target RRC state in the RRC state indication information is different, the operation performed by the UE in the target RRC state is also different.

Wherein, in one embodiment of the present disclosure, the UE may specifically perform at least one of the following operations on the first predefined RRC state:

the UE does not perform DRX;

the UE stops detecting paging information;

the UE stops acquiring the system information;

the UE does not perform neighbor cell measurement operations.

As can be seen from the foregoing, in one embodiment of the present disclosure, when the target RRC state is the first predefined RRC state, it is indicated that the interval value between the service end time of the currently served satellite and the service start time of the next service is greater than the first threshold value (i.e., the time during which the satellite does not provide service for the UE is longer), and at this time, the UE may switch to the first predefined RRC state through the RRC state indication information to implement long-time communication without the base station, so as to avoid the UE from performing an invalid operation and save power consumption of the UE.

In another embodiment of the present disclosure, when the target RRC state is a second predefined RRC state, the UE may specifically perform the following operations on the second predefined RRC state:

In another embodiment of the present disclosure, the RRC state indicating information in step 602 may include only a service start time of the next service of the satellite to the UE. Wherein, in one embodiment of the present disclosure, the interval value between the current time and the service start time of the next service of the satellite to the UE should be greater than the first threshold value.

In yet another embodiment of the present disclosure, the RRC state indication information in step 602 may include a first predefined RRC state and a service start time of a satellite for a next service of the UE.
