Wherein the base station 12 may be an evolved base station (eNB) employed in a 4G system. Alternatively, the base station 12 may be a base station (gNB) in a 5G system employing a centralized and distributed architecture. When the base station 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs).

The execution subject to which the embodiments of the present application relate includes, but is not limited to: a terminal or base station in a wireless communication system.

The interactive procedure of the UE releasing the RRC connection from the RRC connected state is shown in fig. 2.

Step 201: and the UE and the network side equipment in the cell transmit and receive the data packet until the data packet transmission and reception are finished. The network side device may be a base station or the like.

Step 202: the network side equipment sends an RRCConnection release instruction to the UE, and instructs the UE to release the RRC connection.

After the UE receives and transmits the data packet, the time period for the different networks to release the RRC connection is set to be inconsistent, which results in relatively higher power consumption of the UE in some networks.

As shown in fig. 3, a data packet is transmitted and received through the a cell at a certain test site, and the whole transmission process can be found to last for about 10 seconds by observing the transmission power consumption. As shown in fig. 4, the same data packet is transmitted and received through the B cell at the same test site, and the whole transmission process can be found to last for about 20 seconds by observing the transmission power consumption. The a cell is different from the B cell

Through judgment, the time difference of the transmission process of the cell A and the cell B is caused by inconsistent RRC connection release time under different networks, the RRC connection release time is mainly controlled by network side equipment such as a base station, and the standby power consumption current of the UE is directly increased due to the longer RRC connection release time, and the UE consumes more power.

Therefore, how to select a cell for registration, to reduce the power consumption problem caused by the overlong RRC connection release time, and to save the UE power, is a problem to be solved.

As shown in fig. 5, the present exemplary embodiment provides a cell registration method, which may be applied to a user equipment UE for wireless communication, the method including:

step 501: determining release time length of Radio Resource Control (RRC) connection of N cells, wherein N is a positive integer greater than or equal to 1;

step 502: and selecting one cell from N cells for registration at least based on the release duration of each cell.

Here, the release duration of each cell RRC connection may be determined by a UE in a wireless communication system, such as a cellular mobile communication system. The UE may determine a release duration of the cell RRC connection during the historical RRC connection release procedure.

The measurement device may also measure the release duration of the RRC connection of each cell, and send the release durations of the RRC connections of the N cells to the UE through indication information, or store the release durations in a predetermined address, such as a network server, etc. The UE may determine a release duration of the RRC connection of the N cells based on the indication information sent by the measurement device. The UE may also acquire the release duration of the RRC connection of the N cells from the predetermined address.

In practical applications, a UE may frequently switch between a plurality of cells. For example, the UE is located at a position covered by one or more cells, and the UE may frequently switch between the cells due to a change in cell priority or the like. The UE may record a release duration of the RRC connection in each cell and determine the registered cell according to the release duration of the RRC connection in each cell.

After determining the release duration of the RRC connections of the N cells, the UE may select a cell to register based on the actual requirement in combination with the release duration of the RRC connections of each cell. Here, the cell is selected for registration, including but not limited to: access to the cell through random access or handover to the cell through cell handover.

The UE may determine the release duration of the RRC connection based on the same rule.

After the UE completes the packet transmission, the UE does not need to maintain the RRC connection, but since the RRC release information is not received, the UE still needs to maintain the RRC connection to know that the RRC release information is received. The duration between the completion of the last data packet transmission and the receipt of the RRC release information by the UE is controlled by the network device, i.e. the release duration of the RRC connection. The RRC release information may include: the RRCConnectionRelease instruction.

In one embodiment, the UE may select a cell with the shortest release duration of the RRC connection for registration.

The cell with the shortest release duration of the RRC connection is selected for registration, the RRC connection can be quickly released after the data packet is transmitted and received, the duration of the RRC connection state after the data packet is transmitted and received is reduced, the power consumption problem caused by the overlong release duration of the RRC connection is reduced, and the electric quantity of the UE is saved.

For example, the UE determines a release duration M of RRC connection of cell a (denoted a), cell B (denoted B), cell C (denoted C), and cell D (denoted D). Sequencing the cells from short to long according to the length of M time, wherein the shorter the M time is, the higher the cell registration priority is; and obtaining A > B > C > D, namely the shortest release time of the RRC connection of the A cell and the longest release time of the RRC connection of the D cell. The UE may select the cell a with the shortest release duration of the RRC connection for registration. Therefore, the power consumption problem caused by overlong RRC connection release time is reduced, and the electric quantity of the UE is saved

In one embodiment, the UE may select a cell that accommodates a release duration of an RRC connection with a data packet based transceiving frequency for access.

For example, a cell with a release time period longer than a data packet interval period of the RRC connection may be selected for registration. So that a plurality of data packets can be transmitted on one time of establishing the RRC connection, the condition that the RRC connection is released and established in the data packet sending interval is reduced, and the communication load is reduced.

Therefore, based on the release time length of each cell, selecting the cell corresponding to the release time length meeting the communication and power consumption requirements for registration, and meeting the UE communication and power consumption requirements, thereby improving the communication efficiency and saving the UE electric quantity.

In order to improve the uniqueness of the corresponding relation between the release time of the RRC connection and the corresponding cell determined by the UE, the cell can be represented by combining the cell identifier and the cell frequency point. And the situation of error record of the release time length of the cell RRC connection caused by non-unique cell identification of the cell is reduced.

For example, the UE may record, in a list manner, a release duration of RRC connection of each cell, where each cell may be represented by a cell identifier plus a cell frequency point, where the cell identifier plus the cell frequency point corresponds to a release duration of RRC connection, so as to implement a one-to-one correspondence between each cell and the release duration of RRC connection.

When the UE selects a cell for registration, a unique cell can be determined based on the cell identification and the cell frequency point for registration. The situation that the cell is wrongly registered because the cell identification is not unique is reduced.

As shown in fig. 6, the present exemplary embodiment provides a cell registration method, which may be applied to a user equipment UE for wireless communication, the method including:

step 601: determining the signal quality of each cell; the selecting one cell from the N cells for registration based on at least the release duration of each cell includes: and selecting one cell from N cells to register based on the release time length of each cell and the signal quality of each cell.

Step 601 may be implemented alone or in combination with other steps.

Determining the signal quality of each of the cells may include: the UE may perform signal measurements on the camping cells, i.e., each cell while the UE camps on a different cell, to determine the signal quality of each cell.

Determining the signal quality of each of the cells may also include: the UE performs signal measurement on the camping cell and the neighbor cells while camping on the current cell, thereby determining the signal quality of each cell.

The signal quality may include: reference signal received power (RSRP, reference Signal Receiving Power), signal to interference plus noise ratio (SINR, signal to Interference plus Noise Ratio), and the like. The UE may measure the same type of signal in different cells, so that the obtained signal quality may have a better reference value. For example, the UE may measure signals such as Synchronization Signal Blocks (SSBs) of different cells, and/or channel state information Reference signals (CSI-RS, channel State Information-Reference signals), and/or tracking Reference signals (TRS, tracking Reference Signal).

The UE can measure the release time length and the signal quality of the cell, and select the cell with the release time length and the signal quality meeting the requirements to register.

The UE may also preferentially select a cell whose release duration meets the requirement, and then select a cell with the best signal quality from the cells whose release duration meets the requirement for registration.

The UE may also select a cell with the optimal release duration, and then determine whether the signal quality of the cell with the optimal release duration meets the requirement, if so, select the cell for registration, otherwise, determine whether the signal quality of the cell with the suboptimal release duration meets the requirement, and so on to determine that the cell is registered.

The UE may also use the cell signal quality as a preference, select a cell that satisfies the required release duration for registration, and so on.

The above manner of selecting a cell by the UE may be implemented alone or in combination.

Thus, based on the release time length and the signal quality of each cell, selecting the cell meeting the communication and power consumption requirements for registration, and meeting the communication and power consumption requirements, thereby reducing the communication load and saving the electric quantity of the UE.

To meet the communication requirements, a signal quality threshold may be set and cells with cell signal quality less than the signal quality threshold may be eliminated. And sequencing the cells with the cell signal quality greater than or equal to the signal quality threshold according to the release time length only. In this way, the signal quality of the cell determined based on the release duration may meet the requirements of UE communication.

Here, the corresponding release duration weight may be determined for the release duration by normalization or the like. The corresponding signal quality weights may be determined for the signal quality by normalization or the like.

The cell may be selected based on the release duration weight and the signal quality weight.

For example, the shorter the release duration, the larger the release duration weight, and the better the signal quality, the larger the signal quality weight may be set, and then the cell with the largest sum of the release duration weight and the signal quality weight may be selected for registration.

The cell is selected through the release time length weight and the signal quality weight, the release time length and the signal quality which cannot be quantized and combined can be quantized, and the cell is selected for registration based on the quantized release time length and the quantized signal quality, so that the accuracy of cell selection is improved.

In one embodiment, the release duration of the cell is inversely related to a release duration weight corresponding to the release duration of the cell; and the signal quality of the cell is positively correlated with the signal quality weight corresponding to the signal quality of the cell.

For example, the shorter the release duration, the greater the release duration weight may be set; the longer the release duration, the smaller the release duration weight. The better the signal quality can be set, the greater the signal quality weight; the better the signal quality is, the less the signal quality weight.

For example, the UE determines that the release duration M of the RRC connection of cell a, cell B, cell C, and cell D becomes sequentially longer. Then the relationship of cell a, cell B, cell C, and cell D release duration weights A1, B1, C1, and D1 is: a1> B1> C1> D1.

The signal quality relationship of cell a, cell B, cell C and cell D is cell B best, cell a times, cell D again, cell C times the most, then the relationship of cell a, cell B, cell C and cell D signal quality weights A2, B2, C2 and D2 is: b2> A2> D2> C2.

The importance of the release duration weight and the signal quality weight in cell selection may be determined based on the requirements of the UE.

For example, in a scenario requiring a cell to have a shorter release duration, the release duration weight may be set to be greater than the signal quality weight. For example, the release duration weight corresponding to the optimal release duration may be greater than the signal quality weight corresponding to the optimal signal quality.

For a scenario where the release duration and the signal quality of the required cell have the same importance, the release duration weight may be set equal to the signal quality weight. For example, the release duration weight corresponding to the optimal release duration may be equal to the signal quality weight corresponding to the optimal signal quality.

For example, if the relationship of the cell a, cell B, cell C, and cell D release duration weights A1, B1, C1, and D1 is: a1> B1> C1> D1; the relationship of cell a, cell B, cell C and cell D signal quality weights A2, B2, C2 and D2 is: b2> A2> D2> C2.

In the scenario requiring a cell with a short release duration, when selecting a cell by means of weight addition, if the sum of the weights of cell a is maximum, cell a may be selected for registration. If the current UE is registered with cell C, the UE may reselect to cell a. If the current UE is registered with cell a, the UE may remain registered with cell a. If the situation of discontinuous and continuous packet receiving and transmitting in a short time exists, the power consumption of the UE can be reduced to a great extent;

a specific example is provided below in connection with any of the embodiments described above:

1. and detecting the release duration M of the RRC connection after the network receives and transmits the last data packet in a cell (an operator adds a cell frequency point and cell identification information). The release duration M corresponds to the cell (frequency point plus cell identity) in which the UE is registered.

2. And sequencing the cells which can be registered in the area from short to long according to the length of M time, wherein the shorter the M time is, the higher the cell registration priority is.

3. Detecting the signal grid distribution of the UE, and detecting the number of signal grids and a signal boundary value; for example, a signal with two frames below-110 is a two-frame signal, for example, two lower limit values of the signal are set as a threshold S; SINR may also be used as a threshold.

4. And detecting the cell (frequency point plus cell identifier) of the signal meeting S in the step 2, wherein the smaller the M is, the higher the weight of the release duration is, and the weight sequence is assumed to be A > B > C > D.

5. And detecting cells (frequency points and cell identifications) meeting the S signals, and carrying out signal quality weight sequence of B > A > D > C according to RSRP.

6. Since the threshold S has been set, the release duration weight setting needs to be greater than or equal to the signal quality weight, and if the calculated cell (frequency point plus cell identity) weights are the same, the currently registered cell and frequency point are maintained.

7. If the weight of the cell A is heavy, the cell A is preferentially registered, and when the cell A is registered in other cells, the cell A and the frequency point are triggered to be reselected.

8. When the terminal uses the card of the same operator to register in the A cell (frequency point plus cell identifier), if the situation of discontinuous continuous receiving and transmitting package in a short time exists, the power consumption can be reduced to a great extent.
