The radio resource control (Radio Resource Control, RRC) protocol is located at the bottom layer of the third layer of the LTE-a (LTE-Advanced) air interface protocol stack, and an RRC link is established between the terminal device and the network device, where the RRC link mainly includes two types of: an IDLE state (rrc_idle) and a CONNECTED state (rrc_connected).
The IDLE state (rrc_idle) of the RRC link includes two sub-states:
(1) NULL (NULL state): the network end is in an empty state when the network end is just started; or the network device will automatically jump to the null state after an irreparable error such as an underlying link failure occurs.
(2) IDL (idle state): when the network device is in an idle state, the system information can be encoded and a media access control layer (Media Access Control, MAC) sublayer can be configured to broadcast the system information, so that the terminal device can obtain the current system information in real time. The RRC can also configure the terminal equipment to carry out channel measurement in the idle state, so that the network equipment can monitor the channel quality in real time and configure the terminal equipment to realize residence in a more suitable cell. When the network device receives the paging request of another terminal device, the RRC sublayer encodes the paging message through the functional entity of ASN.1 and sends the paging message to the paged terminal.
The state of the connection state (rrc_connected) is similarly divided into three different states, ACC (random access state), CON (connection state) and HO (handover), and will not be described in detail here.
The reference signal received power (Reference Signal Receiving Power, RSRP) is one of the key parameters that can represent the radio signal strength and the physical layer measurement requirements in long-term evolution (LTE) networks.

The network device may also be other types of network devices in future 5G communication systems or future evolution networks.
The terminal device in the embodiment of the present invention may be referred to as a User Equipment (UE). The terminal device may be a personal communication service (personal communication service, PCS) phone, cordless phone, session initiation protocol (session initiation protocol, SIP) phone, wireless local loop (wireless local loop, WLL) station, personal digital assistant (personal digital assistant, PDA) or the like, or a handset, mobile Station (MS), mobile terminal (mobile terminal), laptop or the like, which may communicate with one or more core networks via a radio access network (radio access network, RAN).

The above is merely an example, and the practical application is not limited thereto.
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 that the normal use of a terminal equipment network is not affected, and are beneficial to achieving the purpose of saving power consumption.
Referring to fig. 2, fig. 2 is a schematic diagram of an embodiment of a cell measurement method according to the present invention; in fig. 2, the cell measurement method may include:
201. and when the terminal equipment resides in the current service cell and does not need to switch cells, acquiring the motion data.
The terminal equipment registers a service cell to the network equipment, and the network equipment configures a proper cell for the terminal equipment to realize residence after receiving the application, namely the service cell, and provides network service for the terminal equipment through the service cell.
For example, the terminal device makes a cell measurement first so that the network device configures it with the appropriate serving cell. And when the terminal equipment is started or restarted, acquiring a recently resided cell, selecting a cell with better (such as better signal strength) from the resided cells for access, simultaneously measuring neighbor cells according to measurement configuration information issued by the network equipment, comparing the neighbor cells with the service cells to judge whether the cell needs to be selected from the neighbor cells for switching, if so, performing cell switching, and if not, indicating that the terminal equipment can continuously reside under the current service cell, and further detecting whether the cell measurement can be closed in the process of residing in the current service cell, namely, whether the cell measurement times can be reduced or not, so as to achieve the purpose of saving electricity.
Optionally, when comparing the neighbor cell with the serving cell, parameters such as signal quality, handover priority, and signal-to-noise ratio of the cell may be considered.
202. And if 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 intensity of the current service cell is smaller than or equal to the fluctuation threshold value, closing cell measurement.
Alternatively, the closing of the cell measurement may be closing the measurement for the current serving cell as well as the neighbor cell measurement; alternatively, only neighbor cell measurements are turned off.
Alternatively, the cell measurement is closed by setting preset cell measurement conditions to obtain new cell measurement conditions, so as to achieve the purpose of closing the cell measurement.
Optionally, the signal strength at least includes at least one of: reference signal received power (Reference Signal Receiving Power, RSRP), reference signal received quality (Reference Signal Receiving Quality, RSRQ), signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), and received signal strength indication (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 cell measurement is performed 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, so that cell measurement can be omitted, so that the number of times of cell measurement is reduced under the condition of ensuring that the network of the terminal device is correctly used, electricity is saved, and the standby time of the terminal device is prolonged.
It should be noted that, in the embodiment of the present invention, whether the terminal device can temporarily stop cell measurement is determined by three determination conditions, where the three determination conditions include: the three judging conditions can be triggered and executed simultaneously, cell measurement is carried out normally (namely according to preset cell measurement conditions) when any one of the three judging conditions is not met, and the cell measurement is closed when the three judging conditions are met simultaneously, so that the purpose of saving electricity is achieved, the standby time is prolonged for the terminal equipment, and the performance of the terminal equipment is improved.
It can be seen that, by implementing the above embodiment, when the terminal device resides in the current serving cell, but there is no need to switch cells (there is no need to change cells), determining whether the terminal device moves according to the motion data of the terminal device, and when no movement occurs, 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, turning off cell measurement; it can be seen that the embodiment of the invention flexibly closes the cell measurement through the conditions of the active state, the link state, the signal fluctuation and the like of the terminal equipment, flexibly reduces the cell measurement times under the condition of not influencing the normal use of the network of the terminal equipment, and is beneficial to achieving the purpose of saving the 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 service cell and does not need to switch cells, acquiring the motion data.
302. And under the condition that the motion data indicates that the terminal equipment does not move 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 smaller than or equal to a fluctuation threshold value, the terminal equipment closes cell measurement.
Optionally, under the condition that the motion data indicates that the terminal equipment does not move and the terminal equipment is in a bright screen state, cell measurement is performed according to preset cell measurement conditions.
When the terminal equipment is in a bright screen state, the terminal equipment is indicated to be used, and normal cell measurement can be performed at the moment so as to ensure that the terminal equipment can normally transmit and receive big data, such as data generated by video chat.
Or alternatively, if the motion data indicates that the terminal device does not move and the terminal device is in a black screen state, if the RRC link is in a 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), at this time, the user may be looking at the network state and performing normal cell measurements.
Or under the condition that the motion data indicates that the terminal equipment does not move 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 larger than a fluctuation threshold value, cell measurement is carried out according to preset cell measurement conditions.
The terminal equipment is not moved and is not used, but normal cell measurement is required to ensure that the network of the terminal equipment is normal due to severe fluctuation of the signal intensity of the current service cell.
Therefore, the above embodiment can flexibly close the cell measurement through the conditions of the active state, the use state, the link state, the signal fluctuation and the like of the terminal equipment, flexibly reduce the cell measurement times under the condition of not affecting the normal use of the network of the terminal equipment, and is beneficial to achieving the purpose of saving the power consumption.

403. And the terminal equipment performs neighbor cell measurement 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 strength of the current service cell.
The current serving cell may or may not be the serving cell registered in step 401. For example, after first registering, the current serving cell in step 404 is the serving cell in the previous step 401, but after the terminal device performs cell measurement again and switches cells, 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 device determines whether cell switching is required, wherein if cell switching is required, the process goes to step 406; if a cell change is not required, the process proceeds to step 407.
And determining whether the terminal equipment needs to switch the cell or not by comparing the signal intensity of the current service cell with the signal intensity of the adjacent cell.
406. And the terminal equipment restores the preset cell measurement configuration. Wherein, when execution is completed 406, the process goes to step 402.
It should be noted that, the recovery of the preset cell measurement configuration by the terminal device may include: the terminal equipment resumes the cell measurement according to the preset cell measurement condition, and then normally acquires the measurement configuration information issued by the network equipment, and starts a new round of measurement
407. The terminal device determines whether the motion data indicates that the terminal device is moving. Wherein, when movement occurs, the process goes to step 406, and when no movement occurs, 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 the pedometer.
If the motion data includes acceleration, further optionally, a gravity sensor is built in the terminal device, and the terminal device invokes 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 invokes the three-axis gravity sensor to detect acceleration on three axes, then calculates a combined acceleration, and can analyze the motion state of a user using the terminal device according to the combined acceleration, namely, can be used as the motion state of the terminal device, and can analyze whether the terminal device moves according to the motion state.
408. The terminal device judges whether the screen is in a black screen state. Wherein, when in the non-black screen state, turning to step 409; while in the black screen, the process goes to step 406.
Wherein, the non-black screen state refers to a bright screen state.
409. The terminal device detects whether the RRC link is in an idle state. Wherein, when the RRC link is in an idle state, turning to step 410; while the RRC link is in a non-idle state, the procedure goes to step 406.
410. The terminal equipment judges whether the fluctuation range value of the signal intensity of the current serving cell is smaller than or equal to a fluctuation threshold value. Wherein, when the fluctuation range value is less than or equal to the fluctuation threshold value, the process goes to step 411, and when the fluctuation range value is greater than the fluctuation threshold value, the process goes to step 406.
