The time information application method, the sending method, the terminal and the network side device provided by the embodiment of the application are described in detail through some embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a time information application method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

step 201, the terminal is switched from a source cell to a target cell.

The above-mentioned handover from the source cell to the target cell may be a handover between cells of different network side devices, i.e. a handover from one network side device to another network side device; alternatively, the above-mentioned handover from the source cell to the target cell may be a handover between cells of the same network side device, i.e. a handover from one cell of one network side device to another cell of the network side device; or the above-mentioned handover from the source cell to the target cell may be a handover from the same cell, i.e. the source cell and the target cell are the same cell.

Step 202, the terminal applies time information obtained through a first signaling, wherein the first signaling is a signaling interacted between the terminal and the target cell;

wherein the first signaling comprises one of:

The time information acquired by the terminal application through the first signaling may be that the terminal receives the first signaling, acquires time information corresponding to the first signaling, and applies the time information. The application time information may be calibrating a local clock based on the time information, or transmitting based on the time information, or the terminal radio resource control (Radio Resource Control, RRC) layer may submit the received time information or the information processed based on the received time information to a protocol layer above the terminal RRC layer, etc., which is not limited to the present application.

The signaling matching with the second signaling may be a signaling having a predefined correspondence with the second signaling.

The target signaling is predefined signaling, such as broadcast signaling or dedicated signaling.

In the embodiment of the present application, the first signaling may be a broadcast signaling or a dedicated signaling, and may specifically be determined by the second signaling or the target signaling.

In the embodiment of the application, the time information acquired by the terminal application through the first signaling interacted between the terminal and the target cell can be realized through the steps, so that the terminal application can be used for applying the time information provided by the target cell.

In the embodiment of the application, under the condition that the first signaling comprises the signaling matched with the second signaling, the signaling provided by the time information applied by the terminal before and after switching can be matched, so that the terminal can follow a mechanism of applying the time information in the source cell after switching, and the implementation complexity of the terminal is reduced. For example: if the terminal applies the time information acquired by the broadcast signaling in the source cell, the terminal can apply the time information acquired by the broadcast or dedicated signaling in the target cell after the switching is completed; if the terminal applies the time information acquired through the special signaling in the source cell, after the switching is completed, the terminal applies the time information acquired through the special signaling in the target cell, and correspondingly, the target network side equipment always provides the time information for the terminal through the special signaling.

In the embodiment of the application, under the condition that the first signaling comprises the target signaling, signaling provided by time information applied before switching of the terminal is not considered, after switching, the time information provided by the target signaling is directly applied, and the target network side equipment directly provides the time information for the terminal through the target signaling, so that signaling interaction is not required between the target network side equipment and the source network side equipment for how the terminal applies the time information provided by the source cell, and signaling cost can be saved. For example: in the case that the priority of the dedicated signaling is higher than the priority of the broadcast signaling, the terminal and the target network side device do not consider the priority, and the terminal applies the time information acquired by the dedicated signaling before switching, and the terminal can apply the time information acquired by the broadcast signaling after switching and can also apply the time information acquired by the dedicated signaling.

The target signaling is any one of broadcast signaling and dedicated signaling, and it is understood that the terminal may apply to time information acquired by any one of broadcast signaling and dedicated signaling. For example: the terminal can apply the time information acquired by the broadcast signaling or the dedicated signaling in the target cell after the handover is completed, regardless of the mode of the terminal applied to the source cell.

The target signaling is special signaling, so that the terminal can only apply the time information acquired by the special signaling in the target cell after the switching is completed no matter what mode the terminal applies in the source cell. For example: after the handover is completed, the terminal always applies the time information obtained through the dedicated signaling in the target cell, and correspondingly, the target network side device always provides the time information for the terminal through the dedicated signaling.

As an alternative embodiment, the broadcast signaling may also be referred to as a broadcast message, which may include system messages or system information, such as: the broadcast signaling may include a system information block (System Information Block, SIB) 9. The following is an example of transmitting time information through SIB9 in a New Radio (NR) system, which may be specifically as follows:

the network side device sends a system message SIB9 to the terminal, wherein the SIB9 indicates time information, and the time information may include: reference time information, which may include GPS (or other satellite positioning system) or local time with a minimum granularity of 10 ns.

When the terminal receives the time information, in order to ensure that the terminal and the network side understand and agree with each other the time corresponding to the broadcasted/received time information, the time corresponding to the reference time information received by the terminal is: the boundary of the system frame number (System Frame Number, SFN) where the end boundary of the system message transmission window of the system message is located. For example: the position of SIB9 where the terminal receives the reference time information is (sfn_2, subframe_9), and the system message transmission window of SIB9 is 20 subframes, wherein 10 subframes in 1 SFN are included, and the system information including SIB9 is repeatedly transmitted within the window. The terminal receives the system message window containing the system information (SI message) of SIB9, the ending boundary of which is sfn_4, and the ending boundary of subframe_0, as shown in fig. 3, and the reference time received by the terminal corresponds to the ending boundary time T of sfn_4.

As an alternative embodiment, the dedicated signaling may also be referred to as unicast messages or dedicated messages, and is illustrated below by sending time information in the NR system via unicast messages, specifically as follows:

the network side device sends the indication time information in the unicast message to the terminal, and the reference time information can include at least one of the following: the reference SFN and reference time information may include GPS (or other satellite positioning system) time or local time with a minimum granularity of 10 ns.

Wherein the reference time information corresponds to an end boundary of one reference SFN nearest to a moment when the terminal receives the reference time information; the SFN may be an already past SFN or an SFN that has not yet started. For example: the location where the terminal receives the reference time information is (sfn_2, subframe_1), and the reference SFN value carried in the unicast message is sfn=3, where the moment corresponding to the reference time received by the terminal is the system frame end boundary of the first sfn=3 in the future.

For another example: after repeated retransmission, the position where the terminal finally receives the reference time information is (sfn_4, subframe_1), the reference SFN value carried in the unicast message is sfn=3, and the moment corresponding to the reference time received by the terminal is the system frame end boundary of the previous SFN (i.e. sfn=3 has passed).

As an alternative embodiment, the time information of the terminal application may include a difference between the target time point and a fixed time point, where the fixed time may be defined by a protocol, for example: the fixed time point is a start time (start of GPS time) of day 1, month 6, and day 0 of the Gregorian calendar 1980, and the target time point may be an end boundary of the SFN determined in the embodiment corresponding to the broadcast message and the unicast message.

As an optional implementation manner, in a case where the second signaling is broadcast signaling, the signaling matching the second signaling includes at least one of the following:

broadcast signaling and dedicated signaling.

In this embodiment, if the terminal obtains the time information by the broadcast signaling in the source cell, after the handover is completed, the terminal may apply the time information obtained by the broadcast signaling or the dedicated signaling in the target cell, so that the terminal may apply more time information.

As an optional implementation manner, in a case that the second signaling is dedicated signaling, the signaling matching the second signaling includes:

dedicated signaling.

In this embodiment, it may be achieved that if the terminal applies the time information acquired through the dedicated signaling in the source cell, the terminal also applies the time information acquired through the dedicated signaling in the target cell, so that the implementation complexity of the terminal is reduced, and once the time information provided by the dedicated signaling is applied, the time information provided by the dedicated signaling is always used, regardless of whether handover occurs.

As an alternative embodiment, the first signaling is: in the signaling matched with the second signaling, the terminal acquires and applies the signaling corresponding to the time information for the first time in the target cell; or alternatively

The first signaling is: and the terminal firstly acquires and applies the target signaling corresponding to the time information in the target cell.

The signaling that the terminal first obtains and applies the corresponding time information in the target cell may be that the terminal first obtains the time information in the target cell after the terminal finishes switching, and applies the time information obtained by the signaling. For example: if the terminal applies the time information received from the source cell through the system information before the handover, the terminal may apply the dedicated signaling or the system information to receive the time information from the target cell in the target cell, specifically, may apply the time information obtained for the first time in the target cell after the handover, regardless of whether the time information is received from the target cell through the dedicated signaling or the system information.

The target signaling that the terminal first obtains and applies the corresponding time information in the target cell may be that the terminal first obtains the target signaling of the time information in the target cell after the terminal finishes switching, and applies the time information obtained by the signaling. For example: before the terminal is switched, whether the time information received from the source cell through the dedicated signaling or the broadcast signaling is applied, after the terminal is switched, the terminal can receive the time information from the target cell through the dedicated signaling or the broadcast signaling, specifically, after the terminal is switched, the terminal can apply the time information obtained for the first time in the target cell, and whether the time information is received from the target cell through the dedicated signaling or the system information.

In the embodiment, the time information acquired by the terminal application for the first time can be realized, so that the working efficiency of the terminal is improved.

As an alternative embodiment, in case the first signaling is dedicated signaling, the terminal applies only time information acquired through dedicated signaling to the target cell.

In this embodiment, it may be achieved that once the terminal is applied to the time information acquired through the dedicated signaling, the terminal only applies the time information acquired through the dedicated signaling in the target cell, so as to reduce complexity of the terminal, and the network side device also always provides the time information to the terminal through the dedicated signaling.

As an optional implementation manner, the source cell and the target cell are the same cell, the target signaling is broadcast signaling, and the terminal uses time information acquired through dedicated signaling before switching to the target cell.

The fact that the source cell and the target cell are the same cell can be understood that the terminal performs the handover from the same cell.

In this embodiment, it may be implemented in the source cell, if the terminal has applied the time information provided by the dedicated signaling, but the source cell has no mechanism to enable the terminal to apply the time information provided by the broadcast signaling, in this case, by using the embodiment in which the first signaling is the target signaling, the source cell may trigger the terminal to perform a co-cell handover, so that the terminal may apply the time information provided by the system information. For example: when only a few terminals in the source cell need time information, the source cell provides the time information by using the special signaling, and after the terminals needing the time information become more, the source cell decides to provide the time information in a broadcasting mode, in this case, the source cell can configure the terminals which have applied the special signaling to provide the time information to perform the same-cell switching, and after the switching, the corresponding terminals can apply the time information provided by the system information, so as to reduce the cost brought by sending the related special signaling.

Referring to fig. 4, fig. 4 is a flowchart of a time information sending method provided in an embodiment of the present application, as shown in fig. 4, including the following steps:

step 401, under the condition that a terminal is switched from a source cell to a target cell, a target network side device sends time information to the terminal through a first signaling in the target cell;

Wherein the first signaling comprises one of:

The above-mentioned target network side device sending time information to the terminal through the first signaling in the target cell may also be understood that the target network side device provides time information to the terminal through the first signaling in the target cell.

Optionally, in the case that the second signaling is broadcast signaling, the signaling matching the second signaling includes at least one of:

broadcast signaling and dedicated signaling.

Optionally, in the case that the second signaling is dedicated signaling, the signaling matching the second signaling includes:

dedicated signaling.

Optionally, in the case that the first signaling is dedicated signaling, the target network side device sends time information to the terminal only through dedicated signaling in the target cell.

Optionally, the method further comprises:

the target network side equipment receives indication information, wherein the indication information is used for indicating one of the following:

the terminal needs time service or the terminal needs time information;

the method for acquiring the time information applied by the terminal in the source cell;

and the source cell provides a providing mode of time information for the terminal.

The terminal time service and the terminal time information are not limited to the instruction by the instruction information, and may be, for example: in some embodiments, it may be determined by context information of the terminal.

The manner of acquiring the time information applied by the terminal in the source cell is not limited to the indication by the indication information, for example: in some embodiments, the determination may be made by context information of the terminal, or the terminal may report.

The manner of providing the time information to the terminal by the source cell is not limited to the indication by the indication information, and may be, for example: in some embodiments, the determination may be by context information of the terminal, or the terminal may report.

Optionally, the target network side device receives indication information, including:

The target network side equipment receives a switching request message sent by the source network side equipment, wherein the switching request message comprises the indication information; or alternatively

And the target network side equipment receives the indication information sent by the core network equipment.

Wherein the handover request message is a handover request message for the terminal.

The indication information sent by the core network device may be that, when no direct interface exists between the target network device and the source network device, the source network device sends a handover request message to the core network device, and the core network device sends the indication information to the target network device. The core network device may include an AMF.

In this embodiment, it may be determined how the time information is applied to the terminal before the handover by the indication information, and specifically, the second signaling may be determined by the indication information, so that the time information is provided to the terminal by the first signaling. For example: in the switching process, the source network side equipment informs the target network side equipment whether the terminal obtains time information through the special signaling or not in the original network side equipment, if so, the target network side equipment can only provide the time information for the terminal through the special signaling, otherwise, the target network side equipment can provide the time information for the terminal through broadcasting or the special signaling.

It should be noted that, as an implementation manner of the network side device corresponding to the embodiment shown in fig. 2, a specific implementation manner of the embodiment may refer to a related description of the embodiment shown in fig. 2, so that in order to avoid repeated description, the embodiment is not repeated.

The method provided by the embodiment of the application is illustrated by a plurality of embodiments by taking network side equipment as a base station for example:

example 1:

this embodiment includes a number of aspects, specifically as follows:

scheme 1-1: xn switch (direct interface between base stations)

The source service base station sends a switching request message to the target base station, wherein the switching request message can comprise the following information:

the terminal to be switched needs time service or time information;

the source cell (which may also be referred to as a source serving cell) provides time information to the terminal through dedicated signaling; or the source cell does not allow the UE to acquire the time information through the broadcast message;

after the switching is completed, the target base station sends time information to the terminal through the special signaling.

Scheme 1-2: xn switch (direct interface between base stations)

The terminal to be switched needs time service or time information;

optionally, the following information is included: the source service cell provides time information for the terminal through a broadcast message; or the source cell allows the terminal to acquire time information through the broadcast message;

after the switching is completed, the target base station sends time information to the terminal through a special signaling or a broadcast message.

Scheme 1-3: NG switch (without direct interface between base stations, AMF transfer is needed)

The source service base station sends a handover request message to the AMF, where the handover request message may include the following information:

the terminal to be switched needs time service or time information;

the source service cell provides time information for the terminal through a special signaling; or the source cell does not allow the terminal to acquire time information through the system information;

the AMF sends the information to a target base station;

after the switching is completed, the target base station sends time information to the UE through the special signaling.

Schemes 1-4: NG switch (without direct interface between base stations, AMF transfer is needed)

The source service base station sends a switching request message to the AMF, wherein the switching request message comprises the following information:

the terminal to be switched needs time service or time information;

optionally, the following information is included: the source service cell provides time information for the terminal through a broadcast message; or the source cell allows the UE to acquire time information through a broadcast message;

The AMF sends the information to a target base station;

Schemes 1-5: terminal side behavior

If the terminal receives time information from the source cell by the application through the special signaling before switching, the terminal only receives the time information from the target cell by the application through the special signaling in the target cell;

if the terminal receives time information from the source cell through the system information before handover, the terminal may receive time information from the target cell using dedicated signaling or system information in the target cell. Preferably, after the handover, the terminal uses time information obtained for the first time in the target cell, whether the time information is received from the target cell through dedicated signaling or system information.

In this embodiment, the time provided by the dedicated signaling may be used all the time once the terminal has applied the time provided by the dedicated signaling, regardless of whether a handover occurs, thereby making the implementation of the terminal simple.

Example 2:

this embodiment includes a number of aspects, specifically as follows:

scheme 2-1: xn switch (direct interface between base stations)

The terminal to be switched needs time service or time information;

Scheme 2-2: NG switch (without direct interface between base stations, AMF transfer is needed)

the terminal to be switched needs time service or time information;

the AMF sends the information to a target base station;

In this embodiment, no additional signaling is needed to be interacted between the base stations, so as to save signaling overhead.

Scheme 2-3: terminal side behavior

Before the terminal is switched, whether the time information received from the source cell through the dedicated signaling or the system information is applied, the terminal can receive the time information from the target cell through the dedicated signaling or the system information after the terminal is switched. Preferably, after the handover, the terminal uses time information obtained for the first time in the target cell, whether the time information is received from the target cell through dedicated signaling or system information.

Scheme 2-3 a preferred implementation and application scenario:

In the source serving cell, if the terminal has applied the time information provided by the dedicated signaling; currently, there is no mechanism for the source serving cell to make the terminal apply the time information provided by the system information. At this time, based on the scheme 2-3, the source cell may trigger the terminal to perform a cell-to-cell handover (i.e., the source cell and the target cell are both own cells), so that the terminal may apply the time information provided by the system information.

Scene: when only a few terminals in the source cell need time information, the source cell provides the time information by using special signaling, and when more terminals need time, the source cell decides to provide the time information in a broadcasting mode. At this time, the source cell may let all terminals, to which dedicated signaling has been applied to provide time information, perform the same-cell handover.

Example 3:

this embodiment includes a number of aspects, specifically as follows:
