The technical solutions of the present invention will be further described below by way of examples. As shown in FIG. 2, it is a schematic diagram of an embodiment of a method for preferentially selecting an ENDC cell in an embodiment of the present invention, which may include:

201. Determine a target cell set, where the target cell set includes a first cell set, and the cells in the first cell set are all ENDC cells, and are sorted in order of channel quality.

Optionally, the acquisition of the first set of cells may include: the terminal device acquiring available cells in the initial network scanning phase; Power threshold, and the reference signal receiving quality (Reference Signal Receiving Quality, RSRQ) is greater than or equal to the quality threshold of the cell, add it to the ENDC cell set to obtain the first set of cells; wherein, the first target available cell is one of the available cells and the preset ENDC The cells that are successfully matched in the cell set.

Exemplarily, the UE acquires and scans out all available cells (available cells) in the initial network scanning phase; matches each available cell (available cell) with the cells in the preset ENDC cell set, and determines that the available cells that are successfully matched can be used again. Decision of RSRP and RSRQ. For example, when RSRP>=T1&&RSRQ>=T2, this available cell is added to the ENDC preferred cell set to obtain the first cell set, where T1 is the power threshold and T2 is the quality threshold. It can be understood that each available cell is matched with a cell in the preset ENDC cell set, mainly to determine whether each available cell belongs to a cell in the preset ENDC cell set.

Optionally, the preset ENDC cell set includes a preset static ENDC cell set, and/or, a preset dynamic ENDC cell set. It can be understood that the order of cells in the preset static ENDC cell set and the preset dynamic ENDC cell set is not limited.

Optionally, the cells in the first cell set are sorted in the order of channel quality from high to low, or in the order of channel quality from low to high.

It can be understood that the preset static ENDC cell set may also be referred to as a static pre-embedded ENDC cell set or a static pre-embedded data set, which is not specifically limited. The high-priority ENDC cell information can be pre-buried based on the actual network commissioning experience and the relevant information disclosed by the operator, and a static ENDC cell information set can be maintained.

The preset dynamic ENDC cell set may also be referred to as a dynamic historical ENDC cell set, or a dynamic historical record data set, which is not specifically limited. That is, it can dynamically learn and record historical ENDC cells: this method is used as the UE to dynamically record the ENDC cells encountered during the actual network stay. The various ENDC cell information configured by the overlay network can only be pre-buried a small part of the ENDC cell information according to some prior information. However, in the actual network environment, there are many kinds of cells that are not statically pre-buried but are ENDC, so it is possible to introduce Dynamically learn the way to record historical ENDC cells. Exemplarily, when the actual UE is on the network and finds that the cell is an ENDC cell and does not belong to a cell in the current static pre-buried ENDC cell set, nor does it belong to a cell in the dynamic historical ENDC cell set, the cell will be recorded in the dynamic In the collection of historical ENDC cells. Optionally, since there are multiple combinations in the real network, the dynamic historical ENDC cell set limits a certain number of cell records in order not to affect the network search performance and to meet the requirements of the ENDC cells to quickly set up the network. For example, N, so it can be designed as a queue data structure with a size of N. When the number of ENDC cells recorded in the queue is less than N, the new ENDC cells are directly added to the end of the queue; when the number of ENDC cells recorded in the queue is equal to N , the ENDC cell information at the head of the team is removed, and the new ENDC cell information is added at the tail of the team.

202. Perform network camping according to the order of cells in the first cell set with channel quality from high to low.

Exemplarily, the UE initiates network camping attempts in sequence according to the order of channel quality in the first cell set from high to low.

203 . In the case that the first cell set fails to successfully camp on the network, perform the network camping according to the order of the cells in the second cell set from high to low channel quality.

Optionally, the target cell set further includes a second cell set, and the cells in the second cell set are sorted in order of channel quality.

Optionally, the acquisition of the second set of cells may include but is not limited to the following implementations:

Implementation 1: The terminal device adds the second target available cell to the set of non-ENDC cells to obtain the first set of non-ENDC cells, and uses the first set of non-ENDC cells as the second set of cells; wherein the second target available cell is available In the cells that fail to match with the preset ENDC cell set, the available cells are the available cells in the initial network scanning phase acquired by the terminal device.

Exemplarily, the UE acquires and scans all available cells (available cells) in the initial network scanning phase; matches each available cell (available cell) with the cells in the preset ENDC cell set, and determines that the available cells that fail to match are added to non-ENDC cells A set of cells is preferred to obtain a first set of non-ENDC cells, where the first set of non-ENDC cells may be used as the second set of cells.

Implementation mode 2: the terminal device adds the second target available cell to the set of non-ENDC cells to obtain the first set of non-ENDC cells; the terminal device adds the reference signal received power in the first target available cell to a power threshold less than the power threshold, and/or, A cell whose reference signal reception quality is lower than the quality threshold is added to the first non-ENDC cell set to obtain a second cell set; wherein, the second target available cell is a cell that fails to match the preset ENDC cell set among the available cells.

Exemplarily, the UE acquires and scans all available cells (available cells) in the initial network scanning phase; matches each available cell (available cell) with the cells in the preset ENDC cell set, and determines that the available cells that fail to match are added to non-ENDC cells A set of cells is preferred to obtain the first set of non-ENDC cells. Further, RSRP and RSRQ can be judged for the successfully matched available cells. For example, when RSRP<T1, and/or, RSRQ<T2, the available cell can be added to the second non-ENDC preferred cell set to obtain the second cell set, where T1 is the power threshold and T2 is the quality threshold.

Implementation 3: The terminal device adds cells whose reference signal received power is less than the power threshold and/or whose reference signal received quality is less than the quality threshold in the first target available cell into the set of non-ENDC cells to obtain the second set of cells.

Exemplarily, when the preset ENDC cell set includes a preset static ENDC cell set and a preset dynamic ENDC cell set. E.g:

The preset static ENDC cell set may include: cell1, cell2, and cell3.

The preset dynamic ENDC cell set may include: cell1, cell3, cell5, cell7, cell9, cell11, cell13, cell15, cell17, cell19.

The currently available cells may include: cell1, cell3, cell7, cell9, cell2, cell4, cell6, cell8, and cell10.

Then, each cell in the currently available cells is matched with the preset ENDC cell set, and the successfully matched ENDC cells are: cell1, cell2, cell3, cell7, cell9; the failed ENDC cells are: cell4, cell6, cell8.

Further, the determination of RSRP and RSRQ is performed on the successfully matched ENDC cells, and it is obtained that the ENDC cells with RSRP>=T1&&RSRQ>=T2 are: cell1, cell3, cell7, cell9; wherein, cell2 does not satisfy RSRP>=T1&&RSRQ>=T2.

At this time, the first cell set may include: cell1, cell3, cell7, and cell9.

The second set of cells may include: cell4, cell6, and cell8; and may also include: cell2, cell4, cell6, and cell8.

Optionally, the cells in the second cell set are sorted in the order of channel quality from high to low, or in the order of channel quality from low to high.

Exemplarily, in the case that the UE initiates an attempt to camp on the network in order in the cells in the first cell set but fails to successfully camp on the network, the UE follows the order of the cells in the second set of cells from high to low channel quality in order. Initiate a network attempt. That is, when the cells in the first cell set fail to camp on the network, the terminal device can also camp on the network in the order of the cells in the second cell set from high to low to ensure the normal operation of UE services.

204. In the case that the preset ENDC cell set includes the preset dynamic ENDC cell set, after successfully camping on the network, determine the current serving cell that successfully camps on the network.

205. If the current serving cell belongs to a cell of the second cell set and is currently an ENDC cell, add the current serving cell to the preset dynamic ENDC cell set to obtain an updated preset dynamic ENDC cell set.

Exemplarily, after the UE successfully resides on the network, it is determined whether the current serving cell (serving cell) needs to be added to the dynamic historical ENDC cell set, and the determination criterion can be added to the dynamic historical ENDC cell set when the following conditions are satisfied simultaneously:

Condition 1: The current serving cell is a cell in the second set of cells before the current serving cell;

Condition 2: The current serving cell is currently updated to an ENDC cell.

Optionally, the terminal device adds the current serving cell to the preset dynamic ENDC cell set, and obtains an updated preset dynamic ENDC cell set, which may include:

If the number of cells in the preset dynamic ENDC cell set does not reach the preset threshold, the current serving cell is added to the preset dynamic cell set to obtain an updated preset dynamic ENDC cell set;

If the number of cells in the preset dynamic ENDC cell set has reached the preset threshold, delete some cells in the preset dynamic ENDC cell set, add the current serving cell to the preset dynamic cell set for deleting some cells, and get the updated The preset dynamic ENDC cell set.

Optionally, the terminal device adds the current serving cell to the preset dynamic cell set, and obtains the updated preset dynamic ENDC cell set, which may include: the terminal device adds the current serving cell to the tail of the preset dynamic cell set, and obtains: The updated preset dynamic ENDC cell set;

The terminal device deletes some cells in the preset dynamic ENDC cell set, adds the current serving cell to the preset dynamic cell set from which some cells are deleted, and obtains an updated preset dynamic ENDC cell set, which may include: the terminal device will preset The head cell of the team in the dynamic ENDC cell set is deleted, and the current serving cell is added to the tail of the preset dynamic cell set in which the head cell of the team is deleted to obtain an updated preset dynamic ENDC cell set.

Exemplarily, if the current serving cell where the terminal equipment successfully camps on the network is cell4. Because cell4 previously belonged to a cell in the second set of cells, however, the terminal device now detects that cell4 has been updated to an ENDC cell. Then, the terminal device can update the ENDC cell of cell4 to the preset dynamic ENDC cell set.

Optionally, before updating, it can be judged whether the number of ENDC cells in the preset dynamic ENDC cell set has reached the preset threshold (for example, 12), if not, cell4 can be directly added to the preset dynamic ENDC cell set. In the tail of the queue, the updated preset dynamic ENDC cell set may include: cell1, cell3, cell5, cell7, cell9, cell11, cell13, cell15, cell17, cell19, and cell4.

Optionally, before updating, it can be judged whether the number of ENDC cells in the preset dynamic ENDC cell set has reached the preset threshold (for example, 10), and if so, the number of the team leader of the preset dynamic ENDC cell set can be directly changed. Delete that cell, and then add cell4 to the tail of the preset dynamic ENDC cell set. Then, the updated preset dynamic ENDC cell set may include: cell3, cell5, cell7, cell9, cell11, cell13, cell15, cell17, cell19, cell4.

Optionally, steps 203-205 are optional steps. For the update of the preset dynamic ENDC cell set, reference may be made to the relevant description in step 201 for a specific example, which will not be repeated here.

It should be noted that the embodiments of the present invention can be applied to terminal devices of various manufacturers. In order to satisfy the priority selection of ENDC cells and ensure the channel quality of the selected cells, a static pre-buried cell set and/or a dynamic historical ENDC cell set are designed, and the threshold value T1 of RSRP and the threshold value of RSRQ are set at the same time. The threshold value T2 implements the network search strategy of preferentially selecting the ENDC cell.

In the embodiment of the present invention, a set of target cells in the initial network scanning phase is obtained, wherein the set of target cells includes a first set of cells, and the cells in the first set of cells are sorted according to the order of channel quality; according to the first set of cells In the cell sequence from high to low channel quality, the network is stationed; further, in the case that the network is not successfully stationed in the first cell set, according to the cell sequence from high to low channel quality in the second cell set, the network is stationed. network. The target cell set further includes a second cell set, and the cells in the second cell set are sorted in order of channel quality. It should be noted that the first cell set and the second cell set do not need to be combined.
