Detailed ways

When the UE is in the connected state, the network side configures the neighboring cells around the cell where the UE resides to the UE through measurement configuration. When necessary, the UE measures these neighboring cells and reports the measurement results to the network side. The network side decides whether to handover the UE to another cell according to the measurement result and the current network side load.

When the UE is in the connected state, since the UE does not know its own mobility state, it will perform neighbor cell measurement and report the neighbor cell measurement report according to the measurement parameters in the low-speed motion state. However, when the UE is moving at a high speed or at a medium speed, if the measurement parameters in the low-speed motion state continue to be used, the measurement may not be completed and the cell where the UE resides has changed, resulting in the UE being unable to switch to the target in time. community and off the grid.

In the embodiment of the present invention, when the network side sends the RRC connection reconfiguration message to the user terminal, it carries the movement state indication information of the user terminal, so that the user terminal can know its own current movement state. After the user terminal completes the cell handover, in the connected state, when the user terminal is in the high-speed motion state or the medium-speed motion state, compared with the low-speed motion state, the waiting time between successfully camping in the cell and initiating neighbor cell measurement is shortened time, which shortens the trigger time for reporting neighbor cell measurement reports, enables the network side to perform neighbor cell measurement operations as soon as possible, obtain user terminal neighbor cell measurement reports as soon as possible, and instruct user terminals to perform cell handover as soon as possible, thereby avoiding The occurrence of off-network situations caused by too late measurement and reporting.

In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

An embodiment of the present invention provides a method for controlling a user terminal. With reference to FIG. 1 , specific steps will be described in detail below.

In practical applications, only when the user terminal is in the connected state, the network side can send an RRC connection reconfiguration message to the user terminal. Therefore, before executing the user terminal control method provided by the embodiment of the present invention, it is possible to judge the Whether the terminal is connected. The user terminal being in the connected state means that there is a wireless connection between the user terminal and the base station, and there is data interaction between the two. The following steps are executed only when it is determined that the user terminal is in a connected state.

Step S101, judging whether an RRC connection reconfiguration message sent by the network side is received. When the RRC connection reconfiguration message delivered by the network side is received, step S102 is executed; otherwise, the operation process is ended.

In a specific implementation, the network side may decide whether to handover the user terminal from the cell where it currently resides to other cells according to factors such as the current network load status. For example, when the current network load on the network side is heavy, the user terminal may be handed over from the cell where it currently resides to other cells. The network side may indicate the target cell to which the user terminal is handed over by sending an RRC connection reconfiguration message to the user terminal. When receiving the RRC connection reconfiguration message, the user terminal can switch to the corresponding target cell according to the indication of the RRC connection reconfiguration message.

Step S102, judging whether there is motion state indication information in the RRC connection reconfiguration message. When there is motion state indication information, execute step S103, otherwise, execute step S105.

Step S103, acquiring the motion state indication information from the RRC connection reconfiguration message.

In a specific implementation, the motion state indication information of the user terminal may be generated by the network side when it detects that the user terminal is in a high-speed motion state or a medium-speed motion state, and is used to indicate that the user terminal is in a high-speed motion state or a medium-speed motion state.

That is to say, only when the network side detects that the user terminal is in a high-speed motion state or a medium-speed motion state, the motion state indication information of the user terminal will be generated, and the user terminal will be included in the RRC connection reconfiguration message sent to the user terminal. Indication information of the motion state of the terminal.

In practical applications, the network side can evaluate the movement state of the user terminal based on the mobility information reported by the user terminal when establishing a connection with the network side, or it can evaluate the movement state of the user terminal based on the switching times and switching time of the user terminal in the connected state state.

It should be noted that the high-speed movement state or the medium-speed movement state of the user terminal is not divided according to the actual movement speed of the user terminal, but according to the number of cell handovers completed by the user terminal within a certain period of time. When the number of cell handovers completed by the user terminal within a certain period of time reaches the judgment threshold of the high-speed motion state, it is determined that the user terminal is in the high-speed motion state; The user terminal is in a medium-speed motion state. Wherein, the high-speed motion state determination threshold is greater than the medium-speed motion state determination threshold.

For example, within the preset evaluation time, if the number of cell handovers completed by the user terminal reaches 10 times, it is determined that the user terminal is in a high-speed motion state; if the number of cell handovers completed by the user terminal reaches 8 times, it is determined that the user terminal is in a medium-speed motion state .

Step S104, when the cell handover is completed, according to the motion state indication information, perform the operation corresponding to the connection state in the motion state.

In a specific implementation, after receiving the RRC connection reconfiguration message, the user terminal can perform a corresponding handover operation to switch to the target cell indicated by the RRC connection reconfiguration message. After the handover is successful, the user terminal is in the connected state, and the network side can configure the neighboring cells around the cell where the user terminal currently resides to the user terminal through measurement configuration. The user terminal can measure these neighboring cells and report the measurement results to the base station. The connected state operation of the user terminal includes: neighboring cell measurement operation and reporting of neighboring cell measurement report.

In the embodiment of the present invention, since the RRC connection reconfiguration message carries the moving state indication information of the user terminal, the user terminal can perform the operation corresponding to the connection state in the moving state according to the moving state indication information. When the user terminal is in a high-speed motion state or a medium-speed motion state, the operation in the connected state must meet at least one of the following conditions:

1) When performing neighbor cell measurement operations, the first waiting period of the user terminal in the high-speed movement state or the medium-speed movement state is shorter than the first waiting period of the user terminal in the low-speed movement state. The first time length is: successfully parked in The waiting time between the target cell and the start of the neighbor cell measurement operation.

The first waiting period of the user terminal in the high-speed movement state may be less than or equal to the first waiting period of the user terminal in the medium-speed movement state.

2) When reporting the neighbor cell measurement report, the second waiting period of the user terminal in the high-speed movement state or the medium-speed movement state is shorter than the second waiting period of the user terminal in the low-speed movement state, and the second waiting period is: report the neighbor cell The trigger time of the measurement report.

The second waiting period of the user terminal in the high-speed movement state may be less than or equal to the second waiting period of the user terminal in the medium-speed movement state.

For example, when the user terminal is in the low-speed motion state, the trigger time for reporting the neighbor cell measurement report is t ₁ ; if the user terminal is in the medium-speed motion state, the trigger time for reporting the neighbor cell measurement report is 0.8×t ₁ ; In the motion state, the trigger time for reporting the neighbor cell measurement report is 0.6×t ₁ .

That is to say, in the embodiment of the present invention, when the user terminal is in a high-speed motion state or a medium-speed motion state, the time for initiating neighbor cell measurement and the trigger time for reporting the neighbor cell measurement report are shortened, so that the network side can know the neighbor cell as soon as possible. Measurement reports, so as to decide whether to instruct the user terminal to perform handover as early as possible. When the operation of the user terminal in the connected state satisfies any of the above conditions, the time required for the user to switch to the target cell can be reduced.

Step S105, using the first waiting time and the second waiting time in the low-speed motion state to execute the operation in the connected state.

In the embodiment of the present invention, there may also be a scenario where the motion state indication information of the user terminal is not obtained from the RRC connection reconfiguration message. For example, if the network side detects that the user terminal is not in a high-speed motion state or a medium-speed motion state, it may not need to generate motion state indication information, that is, there will be no motion state indication information in the RRC connection reconfiguration message.

When the user terminal does not obtain the motion state indication information from the RRC connection reconfiguration message, it can be determined that the user terminal is currently in a low-speed motion state or a static state, and the user terminal can use the corresponding first waiting time in the low-speed motion state and the second waiting time. Waiting time to perform connection state operations.

It can be seen that, when the network side sends the RRC connection reconfiguration message to the user terminal, it carries the motion state indication information of the user terminal, so that the user terminal can know its own current motion state. After the user terminal completes the cell handover, in the connected state, when the user terminal is in the high-speed motion state or the medium-speed motion state, compared with the low-speed motion state, the waiting time between successfully camping in the cell and initiating neighbor cell measurement is shortened time, which shortens the trigger time for reporting neighbor cell measurement reports, enables the network side to perform neighbor cell measurement operations as soon as possible, obtain user terminal neighbor cell measurement reports as soon as possible, and instruct user terminals to perform cell handover as soon as possible, thereby avoiding The occurrence of off-network situations caused by too late measurement and reporting.

The embodiment of the present invention also provides another method for controlling a mobile terminal. Referring to FIG. 2 , it will be described in detail through specific steps below.

Step S201, judging whether an RRC connection release message sent by the network side is received. When the RRC connection release message sent by the network side is received, step 202 is executed; otherwise, the operation process ends.

In a specific implementation, when the network side decides to migrate the user terminal from the current camping cell to the idle state according to the current network load status or other factors, an RRC connection release message may be sent to the user terminal. After receiving the RRC connection release message, the user terminal can transition from the connected state to the idle state.

In a specific implementation, when the network side sends the RRC connection release message to the user terminal, the RRC connection release message may carry the movement state indication information of the user terminal. When the user terminal receives the RRC connection release message, it can acquire the motion state indication information of the user terminal therefrom.

Step S202, judging whether there is movement state indication information in the RRC connection release message. When there is motion state indication information, execute step S203, otherwise, execute step S205.

Step S203, acquiring the motion status indication information from the RRC connection release message.

In this embodiment of the present invention, reference may be made to step S103 in the foregoing embodiments of the present invention for generating the exercise state indication information, which will not be described in detail here.

Step S204, according to the exercise state indication information, perform an operation corresponding to the idle state in the exercise state.

In a specific implementation, the operation in the idle state may include cell reselection measurement, cell reselection operation, and cell selection measurement.

In the embodiment of the present invention, the operation of the idle state when the user terminal is in a high-speed motion state or a medium-speed motion state needs to meet at least one of the following conditions:

① When performing cell reselection measurement, the third waiting period of the user terminal in the high-speed or medium-speed movement state is shorter than the third waiting period in the low-speed movement state, and the third waiting period is: from the user terminal to the idle state The waiting time between when the cell reselection measurement is initiated.

The third waiting period of the user terminal in the high-speed movement state may be less than or equal to the third waiting period of the user terminal in the medium-speed movement state.

② During the cell reselection operation, the fourth waiting period of the user terminal in the high-speed movement state or the medium-speed movement state is shorter than the fourth waiting period in the low-speed movement state, and the fourth waiting period is: preset reselection Timer reselection duration.

The fourth waiting period of the user terminal in the high-speed movement state may be less than or equal to the fourth waiting period of the user terminal in the medium-speed movement state.

③ When performing cell selection measurement, the fifth waiting period of the user terminal in the high-speed movement state or the medium-speed movement state is shorter than the fifth waiting period in the low-speed movement state. Waiting time between backing up and performing cell selection measurements.

The fifth waiting period of the user terminal in the high-speed movement state may be less than or equal to the fifth waiting period of the user terminal in the medium-speed movement state.

For example, when the user terminal is in the low-speed motion state, the reselection time of the reselection timer is _t2 ; then the user terminal is in the medium-speed motion state, and the reselection time of the reselection timer is 0.8× _t2 ; When the user terminal is in a high-speed motion state, the reselection duration of the reselection timer is 0.6×t ₂ .

When the operation of the user terminal in the idle state satisfies any of the above conditions, the time for the user terminal to perform cell selection or cell reselection can be shortened.

Step S205, using the third waiting time, the fourth waiting time and the fifth waiting time in the low-speed motion state to execute the operation in the idle state.

In the embodiment of the present invention, there may also be a scenario where the motion state indication information of the user terminal is not obtained from the RRC connection release message. For example, if the network side detects that the user terminal is not in a high-speed motion state or a medium-speed motion state, it may not need to generate motion state indication information, that is, there will be no motion state indication information in the RRC connection release message.

When the user terminal does not obtain the motion state indication information from the RRC connection release message, it can be determined that the user terminal is currently in a low-speed motion state or a static state, and the user terminal can use the corresponding third waiting time and fourth waiting time in the low-speed motion state. The duration and the fifth waiting duration are used to perform idle state operations.

It can be seen that, when the network side sends the RRC connection release message to the user terminal, it carries the motion state indication information of the user terminal, so that the user terminal can know its own current motion state. After the user terminal migrates to the idle state, when the user terminal is in the high-speed motion state or the medium-speed motion state, compared with the low-speed motion state, the waiting time between entering the idle state and initiating cell reselection measurement is shortened, and the Long reselection time, which shortens the waiting time from when the resident cell goes off-line to when the cell selection measurement is performed, so that cell selection and cell reselection operations can be performed as early as possible, thereby avoiding that the user terminal is too late to select the target due to the fast movement speed The community is disconnected from the network.

It can be understood that, in the embodiment of the present invention, in step S101, after it is determined that the RRC connection reconfiguration message delivered by the network side has not been received, steps S201 to S205 may be executed. Similarly, in step S201, after judging that the RRC connection release message sent by the network side has not been received, step S101 to step S105 may be executed. There is no necessary logical sequence between steps S101 to S105 and steps S201 to S205.

The embodiment of the present invention also provides a method for acquiring mobility of a user terminal. Referring to FIG. 3 , the specific steps will be described in detail below.

Step S301, when the user terminal is in a connected state, evaluate the mobility of the user terminal.

In a specific implementation, the network side can evaluate the movement state of the user terminal according to the mobility information reported by the user terminal when establishing a connection on the network side, or it can evaluate the movement state of the user terminal based on the switching times and switching time of the user terminal in the connected state state.

Step S302, when the user terminal is in a high-speed motion state or a medium-speed motion state, generate motion state indication information of the user terminal.

In the embodiment of the present invention, the movement state of the user terminal is evaluated by acquiring the number of times the user terminal completes cell switching within the evaluation time. When the number of cell handovers completed by the user terminal within the evaluation time reaches the judgment threshold of the high-speed motion state, it is determined that the user terminal is in the high-speed motion state; The user terminal is in a medium-speed motion state. The high-speed motion state determination threshold may be greater than the medium-speed motion state determination threshold.

Step S305, judging whether it is necessary to instruct the user terminal to transition to an idle state. When it is necessary to instruct the user terminal to transition to the idle state, perform step S306; otherwise, end the operation process.

Step S306, sending an RRC connection release message to the user terminal.

In the embodiment of the present invention, when the RRC connection release message is sent to the user terminal, the movement state indication information of the user terminal may be carried in the RRC connection release message.

When the user terminal receives the RRC connection reconfiguration message or the RRC connection release message, it can execute step S102 to step S104 or step S202 to step S204.
