Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides an apparatus control method, as shown in fig. 1, including:
step 101: acquiring at least one signal quality parameter of a return signal of network equipment;
step 102: determining an operating state of the network device based at least on at least one signal quality parameter of the backtransmission signal; wherein, the working state at least comprises that the network equipment is in a self-excited state, an abnormal state and a normal state;
step 103: and determining an adjustment mode aiming at the network equipment based on the working state of the network equipment.
Here, the network device may be a wireless repeater in a network structure, for example, specifically, the network device may be a TD-LTE wireless repeater. In order to reliably detect the self-excitation and perform control accordingly, the embodiment proposes to detect whether the network device (i.e. the wireless repeater) is in the self-excitation state by detecting a characteristic signal quantity (such as RSRP, CRS-SINR, or the like) of TD-LTE.
The embodiment determines whether the self-excitation occurs by detecting the signal quality parameters of the network device in different communication states or the change of the signal quality parameters. Without loss of generality, the CRS-SINR is used as the signal quality parameter in the following description, for example, when severe self-excitation occurs, the CRS-SINR cannot be detected, and when slight self-excitation occurs, the CRS-SINR is obviously deteriorated, and when the input signal power is too high, the CRS-SINR is not obviously affected.
It should be understood that, in this embodiment, the determination of the working state is performed based on at least one signal quality parameter of the backhaul signal of the network device, and the determination is performed cooperatively based on which communication state the network device is in, that is, it needs to determine which communication state the network device is in first:
when the communication state of the network equipment is a network searching state, judging whether the network searching is successful, and if the network searching is successful, determining that the network equipment enters a synchronous state;
after the network equipment enters a synchronization state, when the network equipment is in an uplink and downlink transmission link closing state, acquiring a signal quality parameter of a return signal received by the network equipment within a first preset time period, and determining an initial signal quality parameter based on the signal quality parameter of the return signal received within the first time period.
The successful network search may be to determine whether a cell suitable for the network device to reside in is searched, and if the cell is searched, the network search is determined to be successful.
Further, after entering the synchronization state, the network device is first in a state where the uplink and downlink transmission links are closed, and then acquires that the return signal is received within a certain time period, and detects a signal quality parameter of the return signal.
The signal quality parameter may specifically be a parameter such as RSRP, RSSI, SINR, etc. of the detected backhaul signal. That is, at least one of all parameters that can represent the signal strength, or the interference signal strength, or the signal-to-noise ratio of the backhaul signal may belong to the signal quality parameters described in this embodiment, and this embodiment is not exhaustive.
In addition, the first preset time length may be set according to an actual situation, and the length of the first preset time length may be not greater than a time length from entering the synchronization state to the time when the network device is in the synchronization state and the uplink and downlink transmission links are opened.
Before performing the above steps of this embodiment, first, when the uplink and downlink transmission link is in a closed state, the detected signal quality parameter is used as an initial signal quality parameter; it should be noted that the initial signal quality parameter may be an average value of all signal quality parameters measured in the first time period; or, the value may be the maximum or minimum value of all the signal quality parameters measured within the first preset time period; alternatively, the average value of the maximum signal to the minimum signal measured in the first preset time period may be also used. It is not exhaustive here. For example, the RSRP may be an average of all RSRPs, or may be an average of RSRPs, an average of SINRs, an average of RSSIs, and the like.
On the premise of the above processing, in this embodiment, the acquiring at least one signal quality parameter of a backhaul signal of a network device includes:
and after the network equipment enters the synchronization state and is in the uplink and downlink transmission link starting state, acquiring at least one signal quality parameter of the returned signal within a second preset time.
The second preset time period may be set based on an actual situation, and is not limited herein, for example, the second preset time period may be set to be within 1 minute after the network device enters the synchronization state and is in the uplink and downlink transmission link open state, or the second preset time period (for example, 2 minutes) may be set to be started after the network device enters the synchronization state and is 10 minutes after the network device enters the uplink and downlink transmission link open state.
The following is a description of how the determination of the operating state of the network device is made:
said determining an operational status of said network device based on at least one signal quality parameter of said backtransmission signal comprises:
judging whether at least one signal quality parameter of the backtransmission signal is in a first threshold range;
if the at least one signal quality parameter is in a first threshold range, determining that the working state of the network equipment is a self-excitation state;
and if the at least one signal quality parameter is not in the first threshold range, determining that the network equipment is in a normal working state or an abnormal working state based on the initial signal quality parameter and the at least one signal quality parameter.
The determining whether the at least one signal quality parameter is within the first threshold range may be: averaging all signal quality parameters of at least one signal quality parameter, and judging whether the obtained average value is in a first threshold range; or, a maximum signal quality parameter and a minimum signal quality parameter can be selected for averaging, and whether the obtained average value is within the first threshold range or not is judged; alternatively, it may be determined whether the maximum signal quality parameter or the minimum signal quality parameter is within the first threshold range.
Wherein the first threshold range may include at least one of: a threshold range for signal quality, a threshold range for signal-to-noise ratio; for example, the threshold range may include a threshold range corresponding to RSSI (Received Signal Strength Indication), a threshold range corresponding to RSRP (Reference Signal Receiving Power), and a threshold range corresponding to SINR (Signal to Interference plus Noise Ratio).
That is, firstly, based on the comparison between at least one measured signal quality parameter and the corresponding first threshold range, determining whether the signal quality parameter is in a self-excited state; if not, comparing in the second threshold range to judge whether the device is in an abnormal state or a normal state; specifically, the method comprises the following steps:
the determining that the network device is in a normal operating state or an abnormal operating state based on the initial signal quality parameter and the at least one signal quality parameter includes:
determining a signal variation parameter for the network device based on the initial signal quality parameter and the at least one signal quality parameter;
and if the signal change parameter is within a second threshold value range, determining that the network equipment is in a normal working state, otherwise, determining that the network equipment is in an abnormal working state.
After determining that the network device is not in the self-excited state, judging a signal change parameter corresponding to the network device by using the initial signal quality parameter, and then judging an abnormal working state or a normal working state of the network device based on whether the change parameter is in a second threshold range.
In addition, when the abnormal working state is determined, whether the network equipment is in the abnormal working state or in the slight self-excitation state can be further judged.
Further, on the basis of the above processing, there is also a corresponding adjustment mode:
the determining an adjustment mode for the network device based on the operating state of the network device includes:
when the working state of the network equipment is determined to be a self-excitation state, determining that the adjustment mode aiming at the network equipment is to adjust the communication state of the network equipment to be a network searching state;
and when the working state of the network equipment is determined to be an abnormal state, determining that the adjustment mode aiming at the network equipment is to adjust the communication state of the network equipment to be a synchronous state and control an uplink and downlink transmission link to be in a closed state.
That is, when the network device is in a severe self-excited state, the network device is directly controlled to be in an initial state, and network searching is carried out again; otherwise, the synchronization process is resumed.
Based on the idea of the embodiment, a specific processing scheme is provided for the embodiment below in conjunction with fig. 2: the main steps are as follows:
the first step is as follows: state 0: the equipment (namely TD-LTE wireless repeater) is electrified and initialized, at the moment, an uplink amplification link and a downlink amplification link are in a closed state, and the equipment starts to search the network. For example, as shown in fig. 3, the uplink and downlink of the access antenna and the backhaul antenna are both in an off state, and only the backhaul signal is received.
When the device satisfies condition 0: that is, the device searches for a suitable TD-LTE cell to camp on and synchronizes with the target cell, the device enters state 1.
If the synchronization fails, the device is always in the network searching state of state 0.
If the state is re-entered into the state 0, the cell search is preferentially carried out on the frequency points synchronized last time during the network search.
The second step is that: state 1: after the devices are synchronized, the devices detect the quality (such as RSRP or SINR) of the backhaul link signal in a time window T1 (a first preset duration), record an average value in this time period, that is, an average RSRP or an average SINR, as RSRP0 and SINR0, and calculate initial uplink and downlink nominal gains GU1 and GD1, for example, calculation is performed according to RSRP0, and the specific calculation process is not in the scope of the present invention.
After the time T1 has elapsed, state 2 is entered. Note that during this measurement, the uplink and downlink transmission links of the device are still in the off state, i.e. neither the downlink nor uplink forwarding direction outputs power.
The third step: state 2: and after the device opens the uplink and downlink amplification links, continuously measuring the RSRP and SINR values. And detecting whether the following conditions are satisfied:
condition 1: n1 consecutive measurements that do not satisfy the second threshold range, e.g., | RSRPN-RSRP0| ≦ th1& | SINRn-SINR0| ≦ th2
Condition 2: within the time window T2 (the second preset duration), there are N2 measured values, which satisfy the second threshold range, for example, RSRP0-RSRPn > th1| | SINR0-SINRn > th2
Condition 3: within the time window T2, there are N3 measurements that satisfy a first threshold range, such as SINRn ≦ th4& & RSSIn ≧ th6
Condition 4: in a time window T2, N4 measurement values exist, and the RSRPN-RSRP0> th1| | SINRn-SINR0> th2| | | RSSIn is more than or equal to PD-GD1+ th5
Condition 5: the duration in state 2 exceeds T3; in the time window T2, N5 measured values exist, which do not satisfy the first threshold range, specifically (RSRPn < th3) | (SINRn ≦ th4& & RSSIn < th6)
Wherein the priority ordering of the above conditions is: condition 3> condition 5> condition 2> condition 4> condition 1.
When the condition 1 is satisfied, the state 3, normal operation state, is entered.
When condition 2 is satisfied, state 4, a slightly self-excited state, is entered.
When condition 3 is satisfied, state 5 is entered, the severe self-excited state.
When condition 4 is satisfied, state 6, an abnormal state, is entered.
When condition 5 is satisfied, the state 0 is entered, and the initialization is performed again.
Otherwise, state 2 is always in and the RSRP and SINR detection continues for a sliding time window T2.
The fourth step: state 3: the Manger is in normal operation and continuously detects RSRP and SINR within a sliding time window T2.
When condition 2 is satisfied, state 4, a slightly self-excited state, is entered.
When condition 3 is satisfied, state 5 is entered, the severe self-excited state.
When condition 4 is satisfied, state 6, an abnormal state, is entered.
Otherwise, state 3 is always present.
The fifth step: and 4: enters a slightly self-excited state and enters state 7.
And a sixth step: and state 5: enters a severely self-excited state and enters state 0.
The seventh step: and 6: enter abnormal state and enter state 7.
Eighth step: and state 7: the output of the uplink and downlink amplification links is turned off and state 1 is entered.
Therefore, by adopting the scheme, the working state of the network equipment can be determined based on the signal quality of the return signal of the network equipment, including whether the network equipment is in the self-excitation state, and then the adjustment mode aiming at the network equipment is determined based on the working state; therefore, the problem of misjudgment generated in the self-excitation detection processing based on the transmitting power in the prior art can be avoided, the self-excitation state generated due to the problem of the input signal is distinguished, and the accuracy and the reliability of state judgment are improved.
