Background
In a Long Term Evolution (LTE) communication system, Cell Reselection (Cell Reselection) refers to a process in which a User Equipment or a terminal (UE) monitors signal quality of a neighboring Cell and a current Cell in an idle mode to select a best Cell to provide a service signal.
In a multi-carrier hierarchical networking scene, in the process of cell reselection, public reselection priorities of cells with different frequency points are generally configured into a high-low priority strategy, high-load is easy to occur in a high-priority cell, or high-load is easy to occur in a cell with a better coverage signal. However, the equalization effect between some cells is not ideal, and the analysis reason is mainly that some users are released soon after being equalized to the target cell, and the equalization effect is poor because the frequency point of the source cell has high priority, so that the users are easy to reselect back to the equalization source cell after being released.
Therefore, the cell reselection mode in the existing network easily results in poor load balancing effect.

Fig. 1 is a flowchart illustrating a cell reselection control method according to an embodiment of the present invention.
As shown in fig. 1, a cell reselection control method provided in the embodiment of the present invention is applied to a network side device, and the method specifically includes the following steps:
Wherein, Radio Resource Control (RRC) Release (Release), that is, RRC Connection Release; the network side device may be a base station, and each base station is configured with a plurality of cells. The source cell is a cell of the network side equipment, and when the network side equipment detects that the source cell executes RRC release, the target adjacent cell of the source cell is firstly determined.
The network side equipment maintains a neighbor relation list, and when the source cell starts load balancing or RRC release caused by other conditions, the network side equipment determines a target neighbor of the source cell according to the neighbor relation list, wherein the target neighbor is used for receiving UE released by the source cell.
102, acquiring a reflux control state of the target adjacent cell; and determining the reflux control state according to the current load parameter of the target adjacent cell.
After the target neighbor cell is determined, a reflux control state of the target neighbor cell is obtained, wherein the reflux control state is used for indicating whether a cell (the target neighbor cell) is a reflux control cell currently or not, and if the cell is the reflux control cell, the cell is in a high-load state currently and is not suitable for receiving UE released by a source cell.
Specifically, the reflux control state is determined by the network side device according to the load parameter thereof, and if the load parameter indicates that the current load of the target neighboring cell is high and is not suitable for receiving the UE released by the source cell, the UE of the cell is prevented from being switched to the target neighboring cell.
Optionally, the load parameter may be a Physical Resource Block (PRB) utilization of the cell; as an implementation manner, when the PRB utilization is greater than or equal to a preset threshold, it is considered that a cell is currently in a high load state, and the cell is a backflow control cell; otherwise, the cell is a non-reflux control cell.
For example, as shown in fig. 2, if the target neighboring cell B is already in a high load state, and after the source cell a balances the UE to the cell B, the UE may be released again by the cell B soon, and after cell reselection, the UE returns to the cell a again, which causes ping-pong handover of the UE between the cell a and the cell B.
And 103, adjusting the reselection priority of the frequency point of the target adjacent cell according to the reflux control state.
Each cell at least occupies one frequency point, and each frequency point is preset with a reselection priority for reference when UE (user equipment) reselects the cell; in general, the UE preferentially selects the frequency point with the higher frequency point priority. In order to avoid that the UE selects a cell with a higher load, the reselection priority of the frequency point of the target neighbor cell is adjusted according to the reflux control state, for example, the reflux control state indicates that the target neighbor cell is a reflux control cell, and if the current load is higher, the reselection priority of the frequency point is reduced; otherwise, if the backflow control state indicates that the target neighbor cell is a non-backflow control cell and the current load is low, the reselection priority of the frequency point is improved, so that the UE is preferentially switched to the target neighbor cell with the low load.
After the network side equipment adjusts the reselection priority of the frequency point, the network side equipment sends the reselection priority to the UE and informs the UE to release the RRC connection and corresponding wireless resources; and the UE releases the RRC connection and corresponding radio resources after receiving the message, executes the process of leaving the connection state and reselects the cell.
In the above embodiment of the present invention, when detecting that a source cell executes radio resource control RRC release, a network side device determines a target neighboring cell of the source cell, and further obtains a reflux control state of the target neighboring cell; and finally, according to the reflux control state, adjusting the reselection priority of the frequency point of the target adjacent cell, so that the idle UE is preferentially switched to the adjacent cell with low load and is difficult to be switched back to the high-load balancing source cell, thereby improving the load balancing effect and avoiding the influence on the user experience of the UE due to the frequent switching of the UE between the source cell and the target adjacent cell. The embodiment of the invention solves the problem that the cell reselection mode in the existing network easily causes poor load balancing effect.
Optionally, in the foregoing embodiment of the present invention, step 103 includes:
if the backflow control state indicates that the target adjacent cell is a backflow control cell, reducing the reselection priority of the frequency point of the backflow control cell to a first preset value;
and if the backflow control state indicates that the target adjacent cell is a non-backflow control cell, improving the reselection priority of the frequency point of the non-backflow control cell by a second preset value.
The target neighbor cell is indicated by the backflow control state to be a backflow control cell, and when the current load is high, the reselection priority of the frequency point of the target neighbor cell is reduced, and the reselection priorities of the frequency points of the backflow control cell are all reduced to a first preset value; optionally, the first preset value may be a lowest value of reselection priorities of frequency points in the LTE system.
On the contrary, if the backflow control state indicates that the target neighboring cell is a non-backflow control cell and the current load is low, the reselection priority of the frequency point of the target neighboring cell is increased, and the reselection priority of the frequency point of the non-backflow control cell is respectively increased by a second preset value, for example, when the second preset value is 1, the reselection priority of the frequency point of the non-backflow control cell is respectively increased by 1, so that the UE is preferentially switched to the target neighboring cell with the low load.
Optionally, as an implementation manner, if the target neighboring cell is a cell of a third Generation mobile communication system (3rd Generation, 3G) or a second Generation mobile communication system (2rd Generation, 2G), in step 103, the frequency point priority is not adjusted.
As a second example, referring to table 1, table 1 shows preset initial reselection priorities of a group of frequency points (F), where F1 and F3 are target frequency points of a target neighboring cell, F4 is a local frequency point of the source cell, and F2, F5, F6, F7, F8 and F9 are non-target frequency points of a non-target neighboring cell; and F1-F5 are frequency points of an LTE system, F6 and F7 are frequency points of a 3G system, and F8 and F9 are frequency points of a 2G system.
Table 1:
| frequency point | Belonging network | Initial reselection priority | Feature(s) |
| F1 | LTE system | 6 | Target frequency point |
| F2 | LTE system | 6 | Non-target frequency point |
| F3 | LTE system | 5 | Target frequency point |
| F4 | LTE system | 5 | Non-target frequency point |
| F5 | LTE system | 4 | Frequency point of this region |
| F6 | 3G system | 3 | Non-target frequency point |
| F7 | 3G system | 2 | Non-target frequency point |
| F8 | 2G system | 1 | Non-target frequency point |
| F9 | 2G system | 0 | Non-target frequency point |
After the adjustment in the above manner, the reselection priorities after the adjustment of the frequency points are shown in table 2:
table 2:
optionally, in the above embodiment of the present invention, the step of detecting that the source cell executes radio resource control RRC release includes:
and increasing the reselection priority of the frequency point of the source cell by a third preset value.
Referring to the second example, since the frequency point of the local cell of the source cell does not need the backflow control, the priority of the frequency point of the local cell that does not need the backflow control is increased by a third preset value, and the priority of other frequency points that need to backflow is set to be the lowest priority of the configured LTE.
Optionally, in the foregoing embodiment of the present invention, after the step of adjusting the reselection priority of the frequency point of the target neighboring cell, the method further includes:
and carrying the adjusted frequency point reselection priority of the target neighboring cell and/or the frequency point reselection priority of the source cell in the RRC release message, and sending the RRC release message to a terminal.
After the network side equipment adjusts the reselection priority of the frequency point, the reselection priority is carried in the RRC release message and is sent to the UE, and the UE is informed of releasing the RRC connection and corresponding wireless resources; the UE releases the RRC connection and corresponding wireless resources after receiving the message, executes the process of leaving the connection state and reselects the cell; if the RRC connection release message includes Idle Mode Mobility Control Information (IMMCI), the frequency point priority information is stored in the IMMCI.
Optionally, in the foregoing embodiment of the present invention, a load detection period is preset in a cell of the network side device, and the method further includes:
and when the overtime of the timer of the load detection period is detected, and the backflow control state of the cell is determined to be changed relative to the backflow control state of the last period of the current load detection period according to the current load quantity parameter of the cell, updating the backflow control state of the cell.
In each load detection period, if the timer is overtime, detecting whether the current backflow control state of the cell changes relative to the previous period, for example, if the backflow control state of the previous period of the current load detection period indicates that the cell is a backflow control cell, and the backflow control state of the current load detection period indicates that the cell is a non-backflow control cell, sending a non-triggering backflow control indication to the cell, and updating the backflow control state of the cell to be the non-backflow control cell;
or the backflow control state of the last period of the current load detection period indicates that the cell is a non-backflow control cell, and the backflow control state of the current load detection period indicates that the cell is a backflow control cell, then sending a triggering backflow control indication to the cell, and updating the backflow control state of the cell to be a backflow control cell;
therefore, when the reflux control state in the period is not changed relative to the previous period, the indication message does not need to be triggered, and the number of the transmitted messages is reduced.
As a third example, referring to fig. 3, fig. 3 shows a backflow control mechanism in the embodiment of the present invention, and the following steps are mainly performed for a specific cell:
in step 301, the idle-state reflux control switch is turned on.
The idle-state backflow control switch starts an idle-state backflow control algorithm in the starting station, and the network side sends an instruction for triggering the backflow control algorithm to a target adjacent cell overlapped and covered by the same station according to the triggering condition of the load balance of the cell.
Step 302, initializing the overlapping coverage neighbor cell state as a non-reflow control neighbor cell.
When the idle-state backflow control switch is turned on, the states of all the overlapped coverage neighbor cells configured in the cell are initialized to be the non-backflow control neighbor cells.
When the load detection period timer is overtime, whether the adjacent cell is instructed to trigger/not trigger idle state backflow control is determined according to the state of the previous period and the current period, and the principle is that the adjacent cell meets the load balancing selectable adjacent cell condition serving as the local cell, and the adjacent cell synchronously triggers the idle state backflow control.
If the non-backflow control cell in the previous period is judged to be the non-backflow control cell in the current period, triggering backflow control; otherwise, the state is not changed and the action is not carried out.
If the previous cycle is the backflow control cell, judging that the current cycle is the backflow control cell and does not act when the state is not sent to change; otherwise, the state changes, and a backflow control instruction is sent without being triggered.
In order to reduce the number of transmitted messages, an event indication mechanism is adopted, namely after the trigger indication is sent, the trigger indication is not sent repeatedly, and after the trigger indication is sent, the trigger indication is not sent repeatedly.
In the above embodiment of the present invention, when detecting that a source cell executes radio resource control RRC release, a network side device determines a target neighboring cell of the source cell, and further obtains a reflux control state of the target neighboring cell; and finally, according to the reflux control state, adjusting the reselection priority of the frequency point of the target adjacent cell, so that the idle UE is preferentially switched to the adjacent cell with low load and is difficult to be switched back to the high-load balancing source cell, thereby improving the load balancing effect and avoiding the influence on the user experience of the UE due to the frequent switching of the UE between the source cell and the target adjacent cell.
