Wherein the IDLE state (RRC _ IDLE) of the RRC link comprises two sub-states:
(1) NULL (NULL state): the network end is in an empty state when just starting up; or the network equipment automatically jumps to the empty state after irreparable errors such as failure of a bottom link and the like occur.
(2) IDL (idle state): when the network device is in an idle state, the system information may be encoded and a Media Access Control (MAC) sublayer may be configured to broadcast the system information, so that the terminal device may obtain the current system information in real time. In the idle state, the RRC may also configure the terminal device to perform channel measurement, so that the network device may monitor the channel quality in real time and configure the terminal device to camp in a more suitable cell. When the network equipment receives the paging request of another terminal equipment, the RRC sublayer encodes the paging message through the functional entity of the ASN.1 and sends the paging message to the paged terminal.
The state of the CONNECTED state (RRC _ CONNECTED) is also divided into three different states, ACC (random access state), CON (CONNECTED state), and HO (handover), which will not be described in detail herein.

The embodiment of the invention provides a cell measurement method and terminal equipment, which are used for flexibly reducing the cell measurement times under the condition of not influencing the normal use of a terminal equipment network and are beneficial to achieving the purpose of saving power consumption.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a cell measurement method according to an embodiment of the present invention; in fig. 2, the cell measurement method may include:
201. and when the terminal equipment resides in the current serving cell and does not need to switch the cell, acquiring the motion data.
The terminal equipment applies for registering the service cell to the network equipment, the network equipment configures a proper cell for the terminal equipment after receiving the application to realize residence, namely the service cell, and provides network service for the terminal equipment through the service cell.
For example, the terminal device first performs a cell measurement, so that the network device configures an appropriate serving cell for the terminal device. Then, when the terminal device is started up or the network is restarted, the cell which is resided recently is obtained, then a better cell (such as better signal strength) is selected from the resided cells for access, meanwhile, the measurement of the adjacent cell is carried out according to the measurement configuration information issued by the network device, the adjacent cell and the serving cell are compared to judge whether the cell needs to be selected from the adjacent cells for switching, if so, the cell switching is carried out, if not, the terminal device can be resided under the current serving cell continuously, and whether the cell measurement can be closed in the process of residing in the current serving cell is further detected, namely, the cell measurement times can be reduced, so that the purpose of saving power is achieved.
Optionally, when comparing the neighboring cell with the serving cell, parameters such as signal quality, handover priority, signal-to-noise ratio, and the like of the cell may be considered.
202. And under the condition that the motion data indicates that the terminal equipment does not move, if the RRC link is in an idle state and the fluctuation range value of the signal strength of the current service cell is less than or equal to the fluctuation threshold value, the terminal equipment closes the cell measurement.
Optionally, the closing of the cell measurement may be closing of the measurement for the current serving cell and the neighbor cell measurement; alternatively, only the neighbor cell measurements are turned off.
Optionally, the cell measurement is closed by setting a preset cell measurement condition to obtain a new cell measurement condition, so as to achieve the purpose of closing the cell measurement.
Optionally, the signal strength at least includes at least one of the following: reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Received Signal Strength Indication (RSSI).
It can be understood that when the terminal device moves, it indicates that the network around the terminal device changes, and performs cell measurement to detect whether cell switching is needed, and when the terminal device does not move, it indicates that the terminal device is in a static state, and the terminal device can maintain the current serving cell unchanged.
It should be noted that, in the embodiment of the present invention, it is determined whether the terminal device may temporarily stop cell measurement according to three determination conditions, where the three determination conditions include: whether the terminal equipment moves or not, whether an RRC link is in an idle state or not and whether the fluctuation range value of the signal intensity of the current service cell is smaller than or equal to a fluctuation threshold value or not, the three judgment conditions can be triggered to be executed simultaneously, cell measurement is normally carried out (namely according to preset cell measurement conditions) when any one of the three judgment conditions is not met, and the cell measurement is closed when the three judgment conditions are met simultaneously, so that the purpose of saving electricity is achieved, the standby time length of the terminal equipment is prolonged, and the performance of the terminal equipment is improved.
It can be seen that, with the above embodiments, when the terminal device resides in the current serving cell but does not need to switch the cell (it does not need to change the cell), it can be determined whether the terminal device moves according to the motion data of the terminal device, and when the terminal device does not move, if the RRC link is also in an idle state and the fluctuation range value of the signal strength of the current serving cell is less than or equal to the fluctuation threshold value, the cell measurement is closed; it can be seen that the embodiment of the present invention flexibly closes the cell measurement through the conditions of the activity state, the link state, the signal fluctuation, etc. of the terminal device, flexibly reduces the cell measurement times without affecting the normal use of the terminal device network, and is favorable for achieving the purpose of saving power consumption.
Referring to fig. 3, fig. 3 is a schematic diagram of another embodiment of a cell measurement method according to the present invention; in fig. 3, the cell measurement method may include:
301. and when the terminal equipment resides in the current serving cell and does not need to switch the cell, acquiring the motion data.
302. And under the condition that the motion data indicate that the terminal equipment is not moved and the terminal equipment is in a black screen state, if the RRC link is in an idle state and the fluctuation range value of the signal intensity of the current service cell is less than or equal to the fluctuation threshold value, the terminal equipment closes the cell measurement.
Optionally, under the condition that the motion data indicates that the terminal device is not moved and the terminal device is in a bright screen state, cell measurement is performed according to preset cell measurement conditions.
When the terminal device is in a bright screen state, it is indicated that the terminal device is being used, and normal cell measurement can be performed at this time, so as to ensure that the terminal device can normally receive and transmit big data, such as data generated by video chat.
Or optionally, under the condition that the motion data indicates that the terminal device is not moved and the terminal device is in the black screen state, if the RRC link is in the non-idle state, performing cell measurement according to a preset cell measurement condition.
When the terminal device is in the black screen state, but the RRC link is in a non-idle state (connected state), it may be that the user is checking the network state and performing normal cell measurement.
Or, under the condition that the motion data indicates that the terminal device is not moved and the terminal device is in the black screen state, if the RRC link is in the idle state and the fluctuation range value of the signal strength of the current serving cell is greater than the fluctuation threshold, performing cell measurement according to a preset cell measurement condition.
However, since the signal strength of the current serving cell fluctuates dramatically, normal cell measurement is required to ensure that the network of the terminal device is normal.
Therefore, the cell measurement can be flexibly closed through the conditions of the activity state, the use state, the link state, the signal fluctuation and the like of the terminal equipment, the cell measurement times can be flexibly reduced under the condition of not influencing the normal use of the terminal equipment network, and the purpose of saving power consumption can be favorably achieved.

401. the terminal equipment obtains a serving cell configured by the network equipment.
It can be understood that the terminal device applies for registration of the serving cell on LTE to the network device.
402. The terminal equipment receives measurement configuration information sent by the network equipment, wherein the measurement configuration information comprises measurement parameters of same frequency and different frequency.
Wherein, the network device sends the measurement configuration Information through a System Information Block (SIB).
Optionally, the common-frequency and different-frequency measurement parameters include measurement frequency points, and certainly, the measurement period may further include a measurement period, and then, after receiving the measurement configuration information, the terminal device performs cell measurement according to the common-frequency and different-frequency measurement parameters, that is, completes measurement of a cell corresponding to the measurement frequency points.
403. And the terminal equipment measures the adjacent cell according to the measurement configuration information to obtain a measurement result, wherein the measurement result comprises the signal intensity of the cell.
404. The terminal equipment acquires the signal intensity of the current serving cell.
It should be noted that the current serving cell may be the registered serving cell in step 401, or may not be the registered serving cell in step 401. For example, after registration, the current serving cell in step 404 is the serving cell in step 401, but after the terminal device performs cell measurement again and switches the cell, the current serving cell is switched to a new cell, and at this time, the current serving cell is no longer the serving cell registered in step 401.
405. The terminal equipment judges whether the cell needs to be switched, wherein if the cell needs to be switched, the step 406 is turned to; if the handover of the cell is not required, go to step 407.
And determining whether the terminal equipment needs to switch the cell or not by comparing the signal intensity of the current serving cell with the signal intensity of the adjacent cell.
406. And the terminal equipment recovers the preset cell measurement configuration. Wherein, when 406 is executed, the process goes to step 402.
It should be noted that, the recovering, by the terminal device, the preset cell measurement configuration may include: the terminal equipment resumes cell measurement according to the preset cell measurement conditions, further normally acquires the measurement configuration information issued by the network equipment, and starts a new round
407. The terminal equipment judges whether the motion data indicate that the terminal equipment moves. If the movement occurs, the process goes to step 406, and if the movement does not occur, the process goes to step 408.
Optionally, the motion data includes, but is not limited to, at least one of acceleration, angular velocity, and number of steps of a pedometer.
If the motion data comprises acceleration, optionally, a gravity sensor is arranged in the terminal device, and the terminal device calls the gravity sensor to detect the acceleration of the terminal device. For example, the gravity sensor is a three-axis gravity sensor, the terminal device calls the three-axis gravity sensor to detect acceleration on three axes, then a resultant acceleration is calculated, the motion state of a user using the terminal device can be analyzed according to the resultant acceleration, the motion state can be used as the motion state of the terminal device, and whether the terminal device moves or not can be analyzed according to the motion state.
408. The terminal equipment judges whether the screen is in a black screen state. When the screen is in the non-black screen state, turning to step 409; while in the black screen, go to step 406.
Wherein, the non-black screen state refers to a bright screen state.
409. The terminal equipment detects whether the RRC link is in an idle state. Wherein, when the RRC link is in an idle state, go to step 410; when the RRC link is in a non-idle state, go to step 406.
410. The terminal equipment judges whether the fluctuation range value of the signal intensity of the current service cell is smaller than or equal to the fluctuation threshold value. If the fluctuation range value is less than or equal to the fluctuation threshold value, the process goes to step 411, and if the fluctuation range value is greater than the fluctuation threshold value, the process goes to step 406.
411. The terminal equipment closes the cell measurement.
