Embodiment 1

[0040] The network side sets the execution time for an action and notifies the UE through control signaling. The time information in the signaling indicates the time difference between the current time and the set execution time; the time information sent by the network side at different times is different. , because as time changes, the above-mentioned time difference is also changing.

[0041] If the above-mentioned time difference is greater than the range indicated by SFN, the network side will add the parameter SFN_Num in the setting information, indicating that the terminal is required to perform corresponding actions in the following SFN cycles. The value range can be determined according to the length of the specific action execution cycle. The value is a positive integer (1, 2, 3...), and the time length represented by it is: SFN_Num*10.24 (SFN cycle length) seconds; at the same time, setting SFN_offset according to the existing technology means that in the subsequent ...

Embodiment 2

[0059] Embodiment 2 shows another method. The network side indicates the execution cycle of an action in the configuration information, and the terminal performs an action according to the cycle after receiving it; different from Embodiment 1, the network side periodically transmits the above configuration When setting parameters, the SFN_Num will not be decremented, that is to say, the configuration information will remain unchanged. The method in this embodiment is mainly aimed at a scenario that does not require multiple terminals to act at the same time.

[0060] The specific implementation process is as follows:

[0061] The network side sets the period for an action. If the period is greater than the range indicated by the SFN, the parameter SFN_Num is added when setting the period, indicating that the period of the action includes several SFN periods; specific frame number;

[0062] In order for terminals accessing the system at different times to obtain the period in...

Embodiment 3

[0080] In some scenarios, the network will periodically broadcast some information. If the information changes infrequently, the network can configure a cycle for the terminal to read information. The cycle can be set according to the frequency of information changes. In the present invention, the cycle can be Greater than 10.24s.

[0081] In this information, the terminal will be instructed to take corresponding actions. For example, a certain service will start to be transmitted at a certain time. The terminal can monitor the information periodically to obtain the start time of service transmission and start receiving the service at the start time. . That is to say, in the above process, there are two time indications, one is periodic signaling reception, and the other is service effective time; the indication of periodic signaling reception can adopt the method described in Embodiment 2; the indication of service effective time The method described in Example 1 can be used...

Abstract

The invention discloses a method for indicating terminal action time by a network side. The method solves the problem that the terminal action time cannot be indicated when the representation range of an action operating cycle is longer than that of a limiting cycle. The method comprises the following steps that: the network side maintains a base time segment serving as a scale, and the base time segment periodically and cyclically represents time by taking a frame as a unit; and the network side sends configuration information to a terminal, the configuration information carries cycle parameters and offset parameters, the cycle parameters are used for indicating the number of the cycles of the base time segment, and the offset parameters are used for indicating the frame numbers of occurrence in the cycle indicated by the cycle parameters.

Description

technical field [0001] The invention relates to the field of mobile communication. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the network side will maintain a reference time value SFN (System Frame Number, system frame number), using SFN can achieve a certain length of time to make the network side and the terminal side in the time unit can be synchronized, and realize the synchronous transmission or reception at a specific point in time. The length of SFN is 10bit, which means that the range is 0~1023. Every time a wireless frame passes, the SFN value is increased by 1; the length of a wireless frame is 10ms; the specific value of SFN is broadcast in the cell through system broadcast information, specifically located in In the MIB (Master Information Block, master information block) of the system information (SIB, System Information Block). MIB is the most important information in the system information. The sending period ...
