For the convenience of understanding the embodiments of the present application, a communication system applicable to the embodiments of the present application will be described in detail by taking the communication system shown in fig. 1 and 2 as an example. Fig. 1 and 2 are schematic diagrams of wireless communication systems suitable for use with embodiments of the present application. The wireless communication system may comprise a single or multiple network devices, as shown in fig. 1, or a single or multiple terminal devices, as shown in fig. 2.

The power consumption of the digital indoor distribution system is higher than that of the traditional indoor distribution system, and the energy consumption needs to be reduced through technical means. The coverage range of the digital head end is 200-1000 square meters, no user exists within the small range at all, and the digital head end still normally works in the scene and consumes electric energy. Considering the millions of digital head ends in the network, the average time proportion without users is about 35%, and the power-saving space is huge.
A Power Amplifier (PA) of a radio frequency unit of a conventional base station consumes a relatively large amount of energy, and even if the PA does not transmit a signal to the outside, a fixed amount of energy is consumed. Therefore, the traditional energy-saving means is mainly to close the PA, and the PA is closed in a short time when no data is actually sent, so that the energy-saving purpose is achieved. The transmission power of the radio frequency unit of the digital room is extremely low, so the power consumption of the PA is also extremely low, the energy-saving effect is not good by closing the PA, and other obvious energy-saving measures are required.
To save power, the digital headend may be dormant, but when the digital headend is in the dormant state, it is not aware of the terminal devices moving into the coverage area, which may result in a dropped call or a service cannot be initiated from the idle state. Especially, the idle-state terminal device cannot be perceived by the network through other digital head ends, when the idle-state terminal device enters the service range of the dormant digital head end, the terminal device cannot initiate a service request at all because of no signal, and the network considers that the area has no users all the time, so that a long-time coverage hole is caused. In order to solve the above-described problems, the present application provides a communication method, which will be described in detail below.
Fig. 3 is a flowchart illustrating a communication method according to an embodiment of the present application.
As shown in fig. 3, a communication method provided by the present application may include:
301. and the network equipment determines that no terminal equipment is connected within the coverage range of the radio frequency head end within the preset time length, and the radio frequency head end enters a dormant state.
The network device determines whether there is a terminal device under each radio frequency head end, that is, the network device determines whether there is Radio Resource Control (RRC) connection in each radio frequency head end, and if there is no terminal device within a specified time, the network device enters a sleep state, and the specific network device sleeps the radio frequency head end, thereby saving power consumption. The dormant rf headend retains a detection circuit that has the capability to detect a particular signal. For example, in a specific embodiment, the specific signal is a single-frequency dc signal, that is, the detection circuit has a detection capability of a single-frequency dc signal, for example, the network device reserves an independent circuit or a small independently powered circuit in a chip to operate for detecting the single-frequency dc signal, and the other part enters a sleep state.
In this application, the rf head is also referred to as a digital head, and both have the same meaning.
302. And when the terminal equipment determines that the terminal equipment is in a non-signal coverage state, sending a specific signal.
In the normal use process of the terminal equipment, if the operator where the terminal equipment is located is found not to be covered by the wireless cellular network signal, a specific signal is sent according to the agreement. For example, in a specific embodiment, the specific signal may be a single-frequency dc signal, and in this embodiment, the terminal device has a single-frequency dc signal sending capability, specifically, the single-frequency dc signal sending capability may be provided by a terminal device chip, or the single-frequency dc signal sending capability may be provided by an independent circuit.
In a specific embodiment, the frequency point for sending the specific signal is a frequency point with a reference offset fixed frequency, where the reference frequency point is a central frequency point of a cell where the terminal device last resided, or a central frequency point of a cell where the terminal device last received a broadcast message.
In a specific embodiment, if there are multiple frequency points to be transmitted, the terminal device transmits specific signals of the multiple frequency points.
In one specific embodiment, the signal has a duration of 1 second.
In a specific embodiment, the interval duration of the terminal equipment transmitting the specific signal is gradually lengthened. For example, the time interval between the first time of transmitting the specific signal and the second time of transmitting the specific signal by the terminal device is t1, the time interval between the second time of transmitting the specific signal and the third time of transmitting the specific signal by the terminal device is t2, and t2 is greater than t 1.
The terminal device may also be referred to as a terminal, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, or a wireless terminal applied to Virtual Reality (VR), Augmented Reality (AR), industrial control (industrial control), unmanned driving (self driving), remote medical (remote medical), smart grid (smart grid), transportation safety (transportation safety), smart city (smart city), and smart home (smart home). The terminal device and the chip applicable to the terminal device are collectively referred to as a terminal device in the present application. It should be understood that the embodiment of the present application does not limit the specific technology and the specific device form adopted by the terminal device.
303. When the network equipment detects a specific signal, the radio frequency head end exits the dormant state.
After the rf headend of the network device goes to sleep, the digital headend reverts from sleep when a particular signal is detected. For example, if the specific signal is a single-frequency dc signal, the single-frequency dc signal detection circuit is kept after the rf head is in sleep, and when the specific dc signal is detected, the digital head is recovered from the sleep.
304. The terminal device receives the broadcast message.
And when the terminal equipment finds the effective coverage, receiving the broadcast message sent by the network equipment.
305. And if the terminal equipment determines that the terminal equipment is the local operator according to the broadcast message, the terminal equipment stops sending the specific signal.
After the terminal device receives the cellular signal again, the transmission process of the specific signal is stopped. Specifically, when the terminal device finds the effective coverage, the terminal device receives the broadcast message sent by the network device, and when the terminal device determines that the operator is the carrier according to the received broadcast message, the terminal device stops sending the specific signal.
As can be seen from the embodiment corresponding to fig. 3, when the network device determines that there is no terminal device under each radio frequency head end, the digital head end of the network device enters a sleep state, so as to achieve the purpose of saving energy.
As shown in fig. 4, which is a flowchart illustrating a communication method provided in an embodiment of the present application, as shown in fig. 4, the method may include:
401. the terminal device determines whether cellular coverage exists.
402. And when the terminal equipment determines that no honeycomb is covered, the single-frequency direct current signal of the specific frequency point is sent, and the sending interval is gradually lengthened.
The terminal equipment has single-frequency direct-current signal sending capability, can be provided by a terminal equipment chip and can be provided by an independent circuit. The frequency point for sending the signal is a reference frequency point with offset fixed frequency, the reference frequency point is a central frequency point of a last resident cell, and a last resident cell may be a resident cell where the terminal device is currently located or an adjacent cell of the resident cell where the terminal device is currently located. If a plurality of frequency points need to be sent, the terminal equipment needs to poll for sending. When the terminal equipment finds that the terminal equipment is in a non-coverage state, the single-frequency direct-current signal with the fixed frequency point is sent, the signal duration is 1 second, and the sending interval can be gradually lengthened. And when the terminal equipment finds effective coverage, receiving system broadcast, and stopping the action of sending the single-frequency direct current signal after judging that the local operator is the local operator.
As shown in fig. 5, which is a flowchart illustrating a communication method provided in an embodiment of the present application, as shown in fig. 5, the method may include:
501. whether the radio head end has no RRC connection for a certain time.
502. If the radio head end has no RRC connection within a certain time, the radio head end enters a sleep state.
503. And the radio frequency head end receives the uplink frequency point signal of the cell.
504. The network equipment judges whether the radio frequency head end receives a specific single-frequency direct current signal.
505. And if the single-frequency direct current signal is received, the radio frequency head end exits the dormancy.
The digital indoor sub-radio frequency head end judges whether no user exists in a certain time under the coverage of the digital indoor sub-radio frequency head end, and if not, the digital indoor sub-radio frequency head end enters a dormant state. After the digital indoor sub-radio frequency head end is dormant, the single-frequency direct current signal detection circuit is kept to work, and when a specific direct current signal is detected, the digital head end is recovered from the dormancy. The digital room sub-radio frequency head end only detects single-frequency direct current signals corresponding to the configuration frequency points.

It is understood that the network device and the terminal device include hardware structures and/or software modules for performing the functions in order to realize the functions.
