In some embodiments, if the wake-up of the base station fails, the communication device controls the terminal device to still maintain the state of accessing the target satellite, so that the terminal device does not receive the information of the wake-up candidate base station failure sent by the communication device, the network icon of the main interface of the terminal device still displays the satellite network, and the terminal device does not perceive the information of the wake-up base station failure.
In some embodiments, if the base station is not woken up, the communication device regenerates the base station wake-up list according to the positions of the terminal device and the base station at the current time, and wakes up the base station again; if the wake-up base station list is regenerated and then the wake-up base station fails, the control terminal equipment keeps connected with the target satellite, and the network icon of the main interface of the terminal equipment still displays the satellite network; if the list of wake-up base stations is regenerated and then the wake-up base stations are successful, the terminal equipment disconnects from the target satellite, and the network icon of the main interface of the terminal equipment displays the cellular network.
In some embodiments, if the base station is successfully woken up, the communication device controls the terminal device to disconnect from the target satellite, and after the terminal device accesses one of the candidate base stations, the network icon of the main interface of the terminal device displays the cellular network.
As can be seen from the above, the communication method according to the embodiment of the present application may at least include the following scenarios:
the method comprises the steps that a first communication device obtains that a load value of a satellite communication load of a target satellite is smaller than a preset load threshold, qoS of a service applied to the target satellite by terminal equipment is smaller than a preset quality threshold, and the terminal equipment is not in a coverage range of a candidate base station;
second, all candidate base stations wake up to fail.
In the above two scenarios, the communication device controls the terminal device to keep the state of accessing the target satellite, so as to ensure that the terminal device can at least acquire the basic communication service through the target satellite even when the load value of the satellite communication load of the target satellite is greater than or equal to the preset load threshold or the QoS of the service applied by the terminal device to the target satellite is greater than or equal to the preset quality threshold, and the terminal device is not within the coverage range of the candidate base station or wakes up all the candidate base stations. Thereby ensuring wide communication coverage in remote areas.
Because the target satellite consumes solar energy instead of electric energy when working, the base station is kept dormant under the conditions that the target satellite can meet the service QoS requirement of the terminal equipment and the load value of the satellite communication load of the target satellite is smaller than a preset load threshold, so that the power consumption of the base station can be reduced; when the load capacity of the target satellite is exceeded or the QoS provided by the satellite does not meet the service QoS applied by the terminal equipment, part of base stations nearby the terminal equipment are awakened according to the requirement, so that high-quality communication service is provided for users using the terminal equipment, the energy consumption of the base stations is reduced, and the electricity saving of the base stations is realized on the basis of realizing wide coverage in remote areas and guaranteeing the communication quality.
In some embodiments, referring to FIG. 3, the method further comprises the following steps S301-S303.
After accessing to a target base station, when the terminal device is in an idle state, judging whether the terminal device searches a cell meeting a first preset condition, continuously executing S302 when the terminal device searches the cell meeting the first preset condition, and executing S303 when the terminal device does not search the cell meeting the first preset condition.
Wherein the first preset condition includes that the reception power of the signal of the cell by the terminal device is greater than zero and the reception quality of the signal of the cell by the terminal device is greater than zero, and in some embodiments, the first preset condition may be expressed as formulas (2-1), (2-2), (2-3) and (2-4).
Srxlev>0dB (2-1)
Squal>0dB (2-2)
Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–Qoffsettemp (2-3)
Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)–Qoffsettemp
(2-4)
Wherein Srxlev is the receiving power of the terminal equipment to the signal of the cell, square is the receiving quality of the terminal equipment to the signal of the cell, qrxlevmeas is the RSRP value of the terminal equipment measurement cell, qrxLevMin is the lowest receiving level of the cell, qrxLevMinOffset is the lowest receiving level bias of the cell, pcompensation is a preset penalty value set for the UE which cannot reach the maximum power of the cell, so that the UE which cannot reach the maximum power of the cell is more difficult to access the cell; qqualmeas is the reference signal received quality RSRQ value of the cell measured by the terminal device, qqualmein is the minimum received signal quality of the cell, and qqualmeinoffset is the minimum received signal received quality offset value.
Illustratively, the first preset condition may represent an S criterion in 3GPP TSG 38.304 subclause 5.2.3.2 Cell Selection Criterion.
In some embodiments, the communication device wakes up the candidate base station successfully, and after the terminal device accesses one of the target base stations successfully, when the terminal device is in an idle state, the terminal device is controlled to set the frequency priority of the signal of the candidate base station to be higher than the frequency priority of the signal of the target satellite, so as to ensure that the terminal device accesses the candidate base station preferentially.
S302, the terminal equipment is controlled to be switched to the cell meeting the first preset condition.
In some embodiments, when the terminal device is in an idle state, if the terminal device searches for a cell that satisfies the first preset condition, the terminal device is controlled to reselect to a cell that satisfies the first preset condition.
S303, the control terminal equipment disconnects the connection with the target base station and then accesses the target satellite.
In some embodiments, when the terminal device is in an idle state, if the terminal device does not search for a cell that meets the first preset condition, which indicates that all cells corresponding to the candidate base station are unavailable, the terminal device cannot obtain the communication service through the candidate base station, and the terminal device is controlled to disconnect from the target base station and then access the target satellite.
In some embodiments, if the terminal device does not search for a cell satisfying the first preset condition, the terminal device is controlled to disconnect from the target base station and then access the target satellite. The network icon of the main interface of the terminal device displays the satellite network.
As can be seen from the above, in the above method according to the embodiment of the present application, after the terminal device successfully accesses the target base station, the communication service quality of the terminal device is ensured by the mobility management of the terminal device in the idle state, including the flow of cell switching/reselection, that is, the terminal device resides in the cell with the highest receiving power when in the idle state through cell switching; when the terminal equipment cannot search available cells, the terminal equipment is controlled to access the target satellite, so that the communication service quality of the terminal equipment is ensured on the basis of the satellite-ground cooperative wide coverage of a remote area.
In some embodiments, referring to FIG. 4, the method further comprises the following steps S401-S403.
S401, when the terminal equipment is in a connection state, judging whether the terminal equipment meets a second preset condition, continuously executing the step S402 when the terminal equipment meets the second preset condition, and executing the step S403 when the terminal equipment does not meet the second preset condition.
Wherein the second preset condition comprises the terminal device measuring that the RSRP of other cells than the cell to which the terminal device is connected is greater than the preset power threshold.
In some embodiments, after the terminal device successfully accesses to a target base station, when the terminal device is in a connection state, if the terminal device reports an A4 measurement report or an A3 measurement report to the target base station, where the A4 measurement report includes that the RSRP of at least one other cell serving as a neighboring cell exceeds a preset power threshold 1, the A3 measurement report includes that the RSRP of at least one other cell serving as a neighboring cell exceeds a preset power threshold 2 and the RSRP of a cell currently accessed by the terminal device is lower than a preset power threshold 3, and the terminal device is controlled to switch to a cell with the highest RSRP measured by the terminal device so as to ensure that the terminal device accesses to the cell with the highest RSRP.
Wherein the A3 measurement report conforms to the 3GPP protocol standard TSG 38.331subclause 5.5.4.4 Event A3 (Neighbour becomes offset better than SpCell), and the A4 measurement report conforms to the 3GPP protocol standard TSG 38.331subclause 5.5.4.5 Event A4 (Neighbour becomes better than threshold).
S402, controlling the terminal equipment to conduct cell switching to the target cell.
The target cell is a cell with the highest RSRP measured by the terminal equipment in other cells.
S403, the control terminal equipment keeps accessing the current cell.
In some embodiments, after the terminal device successfully accesses one target base station, when the terminal device is in a connected state, if the terminal device does not report an A4 measurement report or an A3 measurement report to the target base station, it indicates that the terminal device does not measure:
the RSRP of the first cell and other cells except the cell accessed by the terminal equipment is higher than a preset power threshold;
the RSRP of the second cell except the cell accessed by the terminal equipment is higher than a preset power threshold 2;
thirdly, the RSRP of the cell which is accessed by the terminal equipment currently is lower than a preset power threshold value 3;
the terminal device does not measure the above information indicating that the RSRP of the cell to which the terminal device has access is highest at this time, and controls the terminal device to remain access the current cell.
As can be seen from the above, in the above method according to the embodiment of the present application, through mobility management of the terminal device in the connected state, the target base station may control the terminal device to always access the cell with the highest RSRP. Therefore, the communication quality of the user using the terminal equipment is ensured on the basis of satellite-ground cooperative wide coverage in a remote area.
In some embodiments, referring to FIG. 5, the method further comprises the following steps S501-S503.
S501, after the terminal equipment accesses the target base station in at least one candidate base station, periodically detecting the state of the candidate base station, judging whether the candidate base station has terminal equipment access within a preset time period, if the communication device detects that the candidate base station has terminal equipment access within the preset time period, executing step S502, and if the communication device detects that the candidate base station has no terminal equipment access within the preset time period, executing step S503.
In some embodiments, the communication device wakes up at least one candidate base station after the terminal device accesses the target base station. And periodically accessing the OAM, the communication device acquires the terminal equipment access states of all the candidate base stations, and controls the awakened base stations which are accessed by the terminal equipment within a preset time period to enter dormancy so as to reduce the power consumption of the base stations. The OAM is a module of the core network responsible for managing operation, maintenance and management of the operator network.
S502, controlling the candidate base station to keep an awake state.
S503, controlling the candidate base station to enter a dormant state.
In some embodiments, the candidate base station temporarily turns off the base station power when it enters a sleep state, at which time the candidate base station does not transmit or receive any radio frequency signals, including broadcasts.
As can be seen from the above, in the above method according to the embodiment of the present application, because the base station in the remote area has idle running due to no terminal device access, by periodically detecting the access state of the terminal device of the candidate base station, the candidate base station without terminal device access in the preset duration is controlled to enter the sleep state, and then the base station sleep is maintained under the condition that the load value of the target satellite is less than the preset threshold and the target satellite can satisfy the QoS of the service applied by the terminal device to the target satellite, so as to achieve the purpose of base station energy saving.
