Background technology

With the continuous development of mobile application to become more diverse with mobile terminal, occur a large amount of using battery powered Mobile terminal, reducing the energy consumption of mobile terminal becomes one of the important technology of future wireless network.Wake on wireless electricity (wake-up Radio, WUR) technology be it is a kind of reduce power consumption of terminal and cost technology, in WUR systems, mobile terminal can be selected intelligently Selecting the suitable time enters battery saving mode, the i.e. main radio of turning-off mobile terminal, makes the terminal works in narrow band mode, and energy It is enough persistently to intercept narrow band signal when closing main radio, once receive the wake-up association (wake-up of network equipment transmission Packet, WUP), then the terminal opens main radio.

In WUR systems, the network equipment needs periodically to send beacon frame, so that with the associated shifting of the network equipment Dynamic terminal knows that the network equipment is in running order.In addition, can also not pass through with the associated mobile terminal of the network equipment The beacon frame perceives the presence of the network equipment.But the network equipment, which periodically transmits beacon frame, can occupy and largely eat dishes without rice or wine The expense of resource, i.e. beacon frame is bigger.

In existing WUR, when the network equipment sends wake-up association to mobile terminal, other mobile terminals can be with Using the wake-up association as beacon frame, when the network equipment sends another wake-up association to another mobile terminal, other-end is again Any movement can be not given using another wake-up association as beacon frame, until the network equipment determines within a preset period of time When terminal sends wake-up association, just beacon frame can be sent to all mobile terminals in the form of broadcast, to reduce the expense of beacon frame.

Invention content

This application provides a kind of method and apparatus of data transmission, can reduce the expense of beacon frame.

In a first aspect, the application provides a kind of method of data transmission in fact, this method includes:

The network equipment determines that in first time period, there are the first wake-up association to be sent, first wake-up association is used for First terminal equipment is waken up, the first time period includes the first delivery time of preset beacon frame, and the beacon frame is week What phase property was sent, the duration of the first time period is greater than or equal to 0, and less than the sending cycle of the beacon frame, wherein when When the duration of the first time period is equal to 0, which is first delivery time;

The network equipment sends first wake-up association, to replace sending the beacon frame.

Optionally, the first time period in the embodiment of the present application can be at least one period, and the first delivery time can Think that at least one delivery time, the first wake-up association can be at least one wake-up association, when first delivery time is multiple hairs When sending the moment, multiple delivery time can be multiple continuous cycles delivery time or multiple discontinuous periodics transmission when Carve, multiple period can be understood as with each delivery time one-to-one period in multiple delivery time, this is more A wake-up association can be understood as wake-up association to be sent in each period, and the embodiment of the present application is not construed as limiting this.

It should also be understood that when the duration of the period is equal to 0, which is the delivery time;The duration of the period When more than 0, the initial time of the period and the duration between finish time include the delivery time or of the period Moment beginning is the delivery time or the finish time of the period is the delivery time.

Optionally, the beacon frame in the embodiment of the present application can be sent in the form of unicast, multicast or broadcast, the application Embodiment is not construed as limiting this.

The method of data transmission provided by the embodiments of the present application, the network equipment determine that there are to be sent in first time period The first wake-up association, which includes the first delivery time of preset beacon frame, which is periodicity sending , the duration of the first time period is greater than or equal to 0, and less than the sending cycle of the beacon frame, the network equipment send this One wake-up association can reduce the expense of beacon frame to replace sending the beacon frame.

It should be understood that the network equipment sends first wake-up association, to replace sending the beacon frame so that the network equipment exists The delivery time is without sending the beacon frame, correspondingly, other terminal devices in addition to the first terminal equipment can by this One wake-up association is as beacon frame, therefore, it is possible to reduce the expense of beacon frame.

In addition, if the network equipment determines that there are to be sent within each delivery time corresponding period of beacon frame Wake-up association, and replace sending beacon frame by sending wake-up association, then while reducing the expense of beacon frame, it is also possible to ensure Terminal device obtains beacon frame within the period of each beacon frame so that the WUR systems of terminal device can carry out periodically sleeping It sleeps, so as to further decrease the energy consumption of terminal device.

In one possible implementation, first wake-up association carries synchronizing information, when the synchronizing information is used for Between synchronous or Frequency Synchronization.

As an alternative embodiment, which can carry synchronizing information field, which uses In the time-domain information or frequency information of the instruction network equipment, in order to which terminal device is set according to the synchronizing information field with the network It is standby to carry out time synchronization or Frequency Synchronization.
