Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1, fig. 1 is a schematic flow chart of a power saving method according to an embodiment of the present disclosure, where the power saving method includes the following steps:
step S10: the narrowband communication device receives the public broadcast signaling.
A narrowband generally refers to a network access method in which a network access speed is lower than a certain value, and in a communication system, a narrowband system refers to a channel in which an effective bandwidth of a modulated signal is much smaller than a carrier frequency or a center frequency of the modulated signal, where a radio channel is a typical narrowband channel. Specifically, the narrowband communication device may be an intercom, such as a narrowband Digital intercom using technologies of Digital Mobile Radio (DMR), Professional Digital Trunking (PDT), pan european trunked Radio (TETRA), and Long Term Evolution (LTE).
The narrow-band communication equipment receives public broadcast signaling, the public broadcast signaling is sent by a narrow-band communication service system, the public broadcast signaling carries a short-link control signaling, and the short-link control signaling contains corresponding power saving indication information.
Step S12: and analyzing the public broadcast signaling to acquire the power saving indication information.
The narrow-band communication equipment analyzes the received public broadcast signaling, acquires a short link control signaling in the public broadcast signaling, and continues to analyze the short link control signaling to acquire power saving indication information. Specifically, the power saving indication information is used to indicate that the narrowband communication device exits/enters the power saving mode.
Step S14: exiting/entering a power saving mode in response to the power saving indication information;
the narrowband communication equipment responds to the power saving indication information analyzed from the public broadcast signaling, so as to exit or enter a power saving mode. The narrow-band communication equipment which exits from the power saving mode enters the working mode, can normally receive service signaling, and the narrow-band communication equipment which enters the power saving mode enters the dormant state, and the dormant state can be periodically awakened to receive the public broadcast signaling, so that whether the narrow-band communication equipment continues to be in the dormant state or not is determined, the power consumption can be obviously reduced, and the cruising ability of the narrow-band communication equipment is improved.
According to the method, the narrowband communication service equipment does not need to repeatedly send the service signaling to cover the sleep time of the narrowband communication equipment, and does not need to wait for downlink service signaling when the narrowband communication equipment is not in sleep, the narrowband communication equipment can respond to the power saving indication information to exit/enter the power saving mode, so that the response speed of private network services can be met, and a better power saving duration result can be achieved.
In one embodiment, the narrowband communication device in the power saving mode and the narrowband communication device in the operating mode both receive the common broadcast signaling, and specifically, the narrowband communication device periodically receives the common broadcast signaling. For a narrowband communication device in a power saving mode, a sleep period of the narrowband communication device may be set to wake up periodically to receive common broadcast signaling. Taking a 30ms timeslot as an example, the narrowband communication device may be set to wake up once every 27.5ms, and the woken narrowband communication device receives 2.5ms public broadcast signaling and enters the next timeslot in a sleep state or in an operating state according to the signaling indication. For the narrow-band communication device in the working mode, the receiving period of the public broadcast signaling can be set, for example, the public broadcast signaling can be received once every 27.5ms, and the narrow-band communication device can normally receive the service signaling in the interval time.
The public broadcast signaling carries a short link control signaling, and based on the DMR communication standard, please refer to fig. 2 and fig. 3, a 28-bit short link control signaling may be split and transmitted through a plurality of consecutive public broadcast signaling, for example, through 4 consecutive public broadcast signaling. Therefore, after receiving the public broadcast signaling, the 4 continuous public broadcast signaling are combined and analyzed to obtain the complete Short link control signaling (Short LC (28)). The short link control signaling contains corresponding power saving indication information for indicating the narrowband communication equipment to exit/enter the power saving mode. The short link control signaling structure comprises a 28-bit information section, the first 4 bits comprise a short link control information operation code (SLCO), the last 24 bits comprise signaling Data information (Data), and the power saving indication information can be expanded into the signaling Data information. The power saving indication information may be identified in various forms. If the address code of the narrowband communication device can be used as the power saving indication information identifier, specifically, the address code of the narrowband communication device that needs to enter/exit the power saving mode can be embedded in the signaling data information, so that the narrowband communication device can determine whether to enter/exit the power saving mode after analyzing the short link control signaling. If the address code in the power saving indication information is consistent with the address code of a certain narrow-band communication device, the narrow-band communication device responds to the power saving indication information.
The address code information in the short link control signaling may include individual call address codes and/or group call address codes. The group calling address code is an address code corresponding to a single narrow-band communication device, and the group calling address code is an address code corresponding to a plurality of narrow-band communication devices. When the narrowband communication service equipment needs to downlink a service signaling to a selected narrowband communication equipment, the narrowband communication equipment can be awakened to exit a power saving mode by carrying an address code corresponding to the narrowband communication equipment in a short link control signaling; usually, a plurality of narrowband communication devices are grouped according to the commonalities, and when a downlink service signaling is required for all the narrowband communication devices in the group, a group call address code corresponding to the group is carried in a short link control signaling, so that all the narrowband communication devices in the group can be waken to exit a power saving mode.
In one embodiment, the address code may be self-contained, assigned upon registration, or a certain number/code. Specifically, the narrowband communication device needs to register with the narrowband communication service system when being powered on or when a base station is replaced, and whether normal operation is allowed in the narrowband communication service system is determined. When the narrowband communication equipment registers, the narrowband communication service system can directly allocate the corresponding address code to the narrowband communication equipment through a registration confirmation signaling, and at the moment, the narrowband communication equipment takes the address code allocated by the system during registration as the standard, namely the address code of the narrowband communication equipment is the address code allocated by the narrowband communication service system during registration; of course, when the narrowband communication device registers with the narrowband communication service system, the narrowband communication service system may not be assigned with its corresponding address code, and the address code of the narrowband communication device is its own address code at this time.
Referring to fig. 4, fig. 4 is a flowchart illustrating another embodiment of a power saving method according to the present application.
The narrow-band communication device registers with the narrow-band communication service system, and confirms whether normal operation under the narrow-band communication service system is allowed. The narrowband communication service system confirms that the narrowband communication equipment is allowed to operate and sends a confirmation signaling to the narrowband communication equipment, wherein the confirmation signaling can contain a corresponding address code which is allocated to the narrowband communication equipment by the narrowband communication service system or does not contain the corresponding address code, and the narrowband communication equipment uses the address code of the narrowband communication equipment. The narrow-band communication equipment keeps a working state, and meanwhile, public broadcast signaling is received periodically according to the setting, the public broadcast signaling is sent by a narrow-band communication service system, wherein the public broadcast signaling carries short-link control signaling, and the short-link control signaling contains corresponding power saving indication information. The narrow-band communication equipment analyzes the public broadcast signaling to obtain a short link control signaling; specifically, the narrowband communication device comprehensively analyzes four continuous public broadcast signals to obtain a short link control signal. After the narrowband communication equipment analyzes the short link control signaling, whether the address code carried by the short link control signaling is matched with the corresponding address code of the narrowband communication equipment is judged.
If the two signals are matched, the narrowband communication service system indicates that downlink service signaling is needed for the narrowband communication service system, and the narrowband communication equipment continues to keep a working state;
if not, counting the unmatched times, judging whether the continuous unmatched times are larger than a threshold value, if so, entering a power saving mode, and if not, continuing to keep the working state. Specifically, the number of consecutive unmatched thresholds may be 3, 4 or 10, and the corresponding threshold setting may be made according to a specific power saving requirement, and is not specifically limited herein. When the number of consecutive mismatches is not greater than the threshold, the narrowband communication apparatus continues to maintain the operating state. At this time, the narrowband communication service system may temporarily have no downlink traffic signaling to the narrowband communication device, and in order to avoid frequent switching between the power saving mode and the operating state of the narrowband communication device, the narrowband communication device maintains the operating state. When the number of continuous mismatching times is greater than the threshold, it indicates that the narrowband communication service system does not downlink the service signaling to the narrowband communication device in the period of time, that is, it indicates that the narrowband communication device does not receive the related service signaling in the continuous period of time, that is, the narrowband communication device is in the no-task standby state, therefore, when the number of continuous mismatching times of the address codes is greater than the threshold, the narrowband communication device enters the power saving mode, and the narrowband communication device entering the power saving mode periodically receives the public broadcast signaling, so that the power consumption is reduced, and the cruising ability is improved. The narrow-band communication equipment entering the power saving mode periodically wakes up to receive the public broadcast signaling, analyzes the public broadcast signaling and acquires a short link control signaling; after the narrowband communication equipment analyzes the short link control signaling, judging whether an address code carried by the short link control signaling is matched with a corresponding address code of the narrowband communication equipment, if so, indicating that a narrowband communication service system needs to send a downlink service signaling to the narrowband communication service system, and exiting the power saving mode by the narrowband communication equipment; if not, it indicates that the narrowband communication service system does not need to send a downlink service signaling to the narrowband communication service system, and the narrowband communication device keeps the power saving mode, thereby prolonging the endurance time.
In the embodiment, the narrow-band communication equipment receives and analyzes the public broadcast signaling to acquire the short link control signaling, the corresponding address code of the narrow-band communication equipment is matched with the address code in the short link control signaling, if the continuous mismatching times are greater than a threshold value, the narrow-band communication equipment enters a power saving mode, otherwise, the narrow-band communication equipment continues to exit the power saving mode, and can receive the service signaling.
The narrowband communication equipment analyzes the received public broadcast signaling to acquire corresponding power saving indication information, and the narrowband communication equipment exits/enters the power saving mode in response to the power saving indication information.
