Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1a is a flowchart of a data receiving method of a low power consumption network according to a first embodiment of the present invention, where the present embodiment is applicable to a case where a low power consumption terminal device continuously receives downlink service data, and the method may be performed by a data receiving apparatus of the low power consumption network, where the apparatus may be implemented by hardware and/or software, and may be generally integrated in an electronic device, for example, a terminal device, and used with a base station. As shown in fig. 1a, the method comprises:
and 110, responding to the uplink service transmission request, exiting the low power consumption mode, and transmitting uplink service data to the base station in an uplink time slot.
In this embodiment, the terminal device and the base station may perform data transmission based on a time division multiple access (Time Division Multiple Address, TDMA) technology, where TDMA is to divide time into periodic time frames, and each time frame is further divided into a plurality of time slots, as shown in fig. 1b, where each time frame includes a broadcast time slot, a downlink time slot, and an uplink time slot. The base station transmits broadcast messages in broadcast time slots, the terminal equipment completes time synchronization with the base station by receiving the broadcast messages, and transmits signals to the base station in uplink time slots, and under the condition that timing and synchronization are met, the base station can respectively receive signals of mobile terminals in each time slot without mixing. Signals sent by the base station to the plurality of terminal devices are sequentially arranged in the appointed time slot for transmission, and each mobile terminal can distinguish and receive the signals sent by the base station to the mobile terminal only by receiving in the appointed time slot. When the base station has no service, the receiving and transmitting window is closed, and the base station is in a low power consumption mode.
In this embodiment, as shown in fig. 1c, when there is uplink service data to be transmitted, the terminal device exits the low power consumption mode, and performs time synchronization with the base station by receiving a beacon frame periodically transmitted by the base station, that is, a broadcast message transmitted by the base station in a broadcast time slot, so as to occupy the uplink time slot to transmit the uplink service data to the base station.
And 120, receiving a broadcast message issued by the base station in a subsequent frame after the uplink service data is sent, opening a receiving window of a designated downlink time slot to receive the downlink service data according to time slot opening indication information carried in the broadcast message, closing the receiving window of the broadcast time slot until the closing condition of the receiving window is met, and entering a low power consumption mode.
In this embodiment, as shown in fig. 1c, after the terminal device finishes sending the next frame of the uplink service data, the terminal device opens the receiving window in the broadcast time slot to receive the broadcast message, and determines whether to open the receiving window of the designated downlink time slot in the frame to receive the downlink service data according to the time slot opening indication information carried in the broadcast message. If the downlink time slot receiving window is opened in the present frame to receive the downlink service data, the receiving window needs to be continuously opened in the broadcasting time slot of the next frame to receive the broadcasting message, so as to judge whether the downlink service data needs to be received in the next frame. It should be noted that, as long as the downlink service reception is started in one frame, the broadcast reception needs to be continuously started in the next frame of the frame, so as to determine whether the downlink service data of the base station is already transmitted according to the time slot start indication information in the broadcast message. If it is determined that the downlink service data is not required to be received by opening the downlink time slot receiving window in the present frame according to the time slot opening indication information, or if no broadcast message is received in the present frame, it is further required to verify whether the receiving window closing condition is satisfied. When the receiving window closing condition is met, the receiving window of the broadcasting time slot of the following frame is closed, the broadcasting message is not received any more, and the low power consumption mode is entered to reduce the energy consumption.
Optionally, according to the time slot opening indication information carried in the broadcast message, opening a receiving window for designating a downlink time slot to receive the downlink service data may include: extracting time slot opening indication information from a broadcast message, wherein the time slot opening indication information comprises: node identification of at least one node to be started for downlink reception and a time slot bitmap; if the time slot opening indication information comprises the node identification of the node, opening a receiving window of the appointed downlink time slot to receive the downlink service data according to the time slot bitmap corresponding to the node identification of the node.
The time slot bitmap is to use one bit to mark whether a downlink time slot opens a receiving window, for example, if the value of the bit corresponding to the downlink time slot is 1, the downlink time slot opens the receiving window to receive downlink service data. If the value of the bit corresponding to one downlink time slot is 0, it means that the downlink time slot does not need to open the receiving window. Since the data is stored in units of bits, a great saving can be made in terms of storage space.
Optionally, determining whether the receiving window closing condition is satisfied may include: if the node identification of the node does not exist in the time slot opening indication information carried by the broadcast messages received by the continuous first number of frames, determining that the receiving window closing condition is met; alternatively, if the broadcast message is not received for the consecutive second number of frames, it is determined that the reception window closing condition is satisfied.
In this embodiment, the first number and the second number may set corresponding values according to the requirement, and the first number may be three and the second number may be four, for example. When the terminal equipment does not detect the node identification of the terminal equipment in the time slot opening indication information carried by the broadcast message, the terminal equipment indicates that the base station has no downlink service data to be transmitted or the downlink service data is transmitted completely. And the terminal equipment continuously receives the broadcast message in three frames, and if the node identification of the terminal equipment still does not exist in the time slot opening indication information of the broadcast message in the three frames, the terminal equipment determines that the receiving window closing condition is met, and closes the broadcast reception to enter a low power consumption mode. If the terminal device does not receive the broadcast message of the base station during this period, the terminal device continues to keep the receiving window of the broadcast slot open and normally receives the broadcast message, as shown in fig. 1 d. If the continuous four frames do not receive the broadcast message, the terminal equipment is determined to be temporarily disconnected with the base station, the terminal equipment closes the receiving window of the broadcast time slot, and the low power consumption mode is entered.
In the embodiment of the invention, the terminal equipment responds to an uplink service sending request, exits from a low-power consumption mode and sends uplink service data to the base station in an uplink time slot; and receiving a broadcast message issued by the base station in a subsequent frame after the uplink service data is sent, starting a receiving window of an appointed downlink time slot to receive the downlink service data according to time slot starting indication information carried in the broadcast message, closing the receiving window of the broadcast time slot until a receiving window closing condition is met, and entering a low-power consumption mode, thereby solving the problem that the low-power consumption terminal equipment is not friendly to the receiving of the downlink service data in the prior art, realizing continuous receiving of the low-power consumption terminal equipment when the downlink service data is received, and automatically switching to the low-power consumption mode after the downlink service data is received.

As shown in fig. 2, the method includes:
In this embodiment, after receiving uplink service data sent by a terminal device in an uplink timeslot, a base station determines that the terminal device is in an active state, and at this time, the base station detects whether downlink service data needs to be sent to the terminal device, and notifies, through a broadcast message of a next frame, whether information that downlink reception is needed to be sent to the terminal device.
Optionally, the time slot opening indication information includes: node identification of at least one node to be started for downlink reception and a slot bitmap. In this embodiment, if it is determined that there is downlink service data to be sent to the terminal device, a downlink timeslot is allocated to the terminal device, and timeslot opening indication information matched with the terminal device is written in a broadcast message of a next frame, that is, a node identifier of the terminal device and a timeslot bitmap indicating the allocated downlink timeslot, so that the terminal device can open a receiving window of the downlink timeslot to receive the downlink service data according to the broadcast message.
In this embodiment, if the base station does not have downlink service data that needs to be sent to the terminal device, no downlink timeslot is allocated to the terminal device, and timeslot opening indication information that matches with the terminal device is not carried in a broadcast message of a next frame, so when the terminal device receives the broadcast message, it can be determined that the downlink service has been received according to the fact that there is no node identifier of the node in the timeslot opening indication information of the broadcast message, and it can be further verified whether the broadcast message of the first number of frames meets the condition of closing the receiving window, and then the broadcast timeslot receiving window is closed when the condition of closing the receiving window is met, and the low power consumption mode is entered.
In the embodiment of the invention, after receiving uplink service data sent by the terminal equipment in an uplink time slot, the base station detects whether downlink service data to be sent to the terminal equipment exists or not; if the time slot opening indication information matched with the terminal equipment is carried in the transmitted broadcast message, the terminal equipment is instructed to open a receiving window for designating a downlink time slot to receive downlink service data, if the time slot opening indication information does not exist, the time slot opening indication information matched with the terminal equipment is not carried in the transmitted broadcast message, so that the terminal equipment closes the receiving window of the broadcast time slot when the condition for closing the receiving window is confirmed to be met, and the terminal equipment enters a low-power mode, thereby solving the problem that the low-power terminal equipment is not friendly to the reception of the downlink service data in the prior art, realizing continuous reception of the low-power terminal equipment when the downlink service data is received, and automatically switching to the low-power mode after the reception of the downlink service data is completed.
