Summary of the application
In reality, there are many users of the same vehicle, for example, users who take the same high-speed train and high-speed bus, all access to the same cell because the physical spatial positions are the same, as shown in fig. 1, all user terminals located in the cell a can continuously perform signal measurement and reporting of the cell and adjacent cells, and frequently perform cell switching, which is very power-consuming for the user terminals and increases the data processing amount of the base station.
In view of the above technical problems, the inventor finds that all user terminals in a same-vehicle scene are connected to the same base station/cell, and the signal strength and the measurement result of all the user terminals are basically the same, so the idea of the present application is to provide a cell measurement control method, in which a core network device divides the same-vehicle user terminals into a first type of user terminals and a second type of user terminals, wherein the first type of user terminals need to perform normal measurement reporting and signaling switching interaction according to the existing flow, and the second type of user terminals do not need to perform measurement reporting, thereby effectively reducing the power consumption of the second type of user terminals.
Having described the basic principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Example 1:
the present embodiment provides a cell measurement control method, which is applied to a core network device, and as shown in fig. 2, the method includes:
step S102: and acquiring the user terminal of the same vehicle.
In this embodiment, before the user terminal of the same vehicle is obtained, the user terminal of the same vehicle may be identified by the core network device, for example, the core network device may identify the user terminal of the same vehicle according to a preset clustering algorithm, big data analysis, and the like; or, the core network device may also identify the user terminal in the same vehicle according to the location information, the moving speed, and the currently accessed cell information of the user terminal, and at this time, all the user terminals have sent an RRC (Radio Resource Control) connection reconfiguration complete message to the source base station, and all the user terminals measure the signal strengths of the current cell and the neighboring cell and report the measurement result to the source base station.
Optionally, identifying the user terminal in the same vehicle according to the location information of the user terminal, the moving speed, and the currently accessed cell information may specifically include:
acquiring the position information, the moving speed and the currently accessed cell information of each user terminal;
and identifying the user terminals with the same cell information, similar position information and similar moving speed which are accessed currently in all the user terminals as the same vehicle user terminal.
In this embodiment, since the location information of the co-user is very close and the moving speed is close, and the co-user accesses the same cell, the user terminals with the same currently accessed cell information, the same location information and the same moving speed in all the user terminals can be identified as the co-user terminals. Specifically, the core network device may first acquire all user terminals with the same currently accessed cell information, then acquire all user terminals with the same cell information and the same position distance difference values within a preset first range according to the position information, then acquire all user terminals with the same position distance difference values within a preset first range and the same moving speed difference values within a preset second range according to the moving speed, and finally identify all user terminals with the same moving speed difference values within the preset second range as the user terminals for the same vehicle. For example, all the user terminals with position distance difference values within a preset first range among all the user terminals may be obtained according to the position information, and then the step of judging the cell information and the moving speed may be performed. It should be noted that the method for identifying the co-vehicle user terminal is only an example, and the implementation includes but is not limited to the above identification method, and other methods may be used to identify the co-vehicle user terminal in this embodiment.
Step S104: and dividing the user terminals of the same vehicle into a first class of user terminals and a second class of user terminals.
In this embodiment, the number or the ratio of the first class user terminals and/or the second class user terminals may be configurable, for example, the core network device may divide the in-vehicle user terminals into the first class user terminals and the second class user terminals according to a preset ratio, and assume that the preset ratio is 2: and 8, taking 20% of the user terminals of the same vehicle as the first type of user terminals, and taking 80% of the user terminals of the same vehicle as the second type of user terminals, wherein the first type of user terminals need to carry out measurement reporting all the time according to the existing flow, and the second type of user terminals do not need to carry out measurement reporting so as to save electric quantity.
In this embodiment, since the first-class user terminals need to consume electric power for measurement and reporting, if the electric power residual amount of the first-class user terminals is insufficient at this time, normal use of other services is certainly affected, and therefore, in addition to the random classification according to the proportion or the number, the core network device may also classify the same-vehicle user terminals into the first-class user terminals and the second-class user terminals according to electric power information reported by the same-vehicle user terminals respectively, so as to save the electric power of the user terminals with insufficient electric power residual amount. Specifically, the core network device may send an electric quantity reporting request to all the user terminals of the same vehicle, respectively, and request the user terminals of the same vehicle to report the electric quantity. After receiving the request, each in-vehicle user terminal respectively replies the electric quantity of the user to the core network device, where the electric quantity information may be a specific remaining electric quantity value or information used for roughly representing the electric quantity condition, for example, 00 represents that the electric quantity is extremely low; 01 denotes low battery; 10 represents the electric quantity is medium; 11 indicates that the electric quantity is high, etc. After receiving the electric quantity information respectively reported by each co-vehicle user terminal based on the electric quantity reporting request, the core network equipment takes the co-vehicle user terminal with the electric quantity information larger than a preset electric quantity threshold value or the electric quantity information indicating that the electric quantity is high as a first-class user terminal, and takes the rest co-vehicle user terminals as a second-class user terminal. Or, the user terminal in the same vehicle may also actively report the electric quantity information in the vacant fields of some existing messages (for example, the vacant fields of the existing measurement report messages), and the remaining situation of the electric quantity is roughly represented by several vacant bits.
Step S106: and sending a measurement report stopping indication message to each second type user terminal so that the second type user terminals stop performing signal measurement on the current cell and the adjacent cell or stop sending the respective corresponding measurement results of the current cell and the adjacent cell to the source base station.
In this embodiment, the core network device sends a measurement report stop indication message to each second type user equipment, indicating that it does not need to send respective measurement results of the current cell and the neighboring cell to the source base station, or indicating that it does not need to perform signal measurement of the current cell and the neighboring cell and send respective measurement results of the current cell and the neighboring cell to the source base station. And after receiving the indication message, the second type of user terminal suspends measuring or reporting the signals of the current cell and the adjacent cell so as to save the electric quantity.
Optionally, after sending the measurement report stop indication message to each second class user equipment, the method may further include:
receiving a second type user terminal information acquisition request sent by a target base station, wherein the second type user terminal information acquisition request is sent after the target base station receives a switching request which is sent by a source base station and carries identity identification information of all first type user terminals;
and sending the identity identification information of all the second class user terminals to the target base station, wherein the identity identification information of the second class user terminals is used for triggering the target base station to send indication information for indicating that the switching preparation of the first class user terminals and the second class user terminals is completed to a source base station, so that the source base station sends RRC connection reconfiguration messages to all the first class user terminals and the second class user terminals respectively after receiving the indication information, and the first class user terminals and the second class user terminals are switched to the target base station.
In this embodiment, when the cell handover is required, all the user terminals in the same vehicle need to perform the cell handover. Specifically, the source base station receives the measurement result of the first user terminal, and triggers a handover decision when it determines that all the first user terminals or the first user terminals higher than a certain threshold (for example, 80%) need to be handed over, and the source base station sends a handover request to the target base station to notify the target base station of a handover preparation, where the handover request carries identification information of all the first type user terminals, and the identification information may be related information that can indicate the Identity of the first type user terminal, such as an IMSI (International Mobile Subscriber Identity), so that the target base station prepares wireless resources for the first type user terminal. And after receiving the switching request, the target base station sends a second type user terminal information acquisition request to the core network equipment so as to acquire the information of the second type user terminal. The core network equipment sends the identity identification information of all the second type user terminals to the target base station, and after the target base station prepares radio resources for the target base station, the target base station sends indication information for indicating that the switching preparation of the first type user terminals and the second type user terminals is completed, so that the source base station respectively sends RRC connection reconfiguration messages to all the first type user terminals and the second type user terminals after receiving the indication information and informs the first type user terminals and the second type user terminals of the information of the target cell. The first type user terminal and the second type user terminal are accessed into the target cell and send RRC connection reconfiguration finishing messages to the target cell.
According to the cell measurement control method provided by the embodiment of the invention, the same-vehicle user terminals are obtained and are divided into the first-class user terminals and the second-class user terminals, and the measurement report stopping indication message is sent to each second-class user terminal, so that the second-class user terminals can stop performing signal measurement on the current cell and the adjacent cell, the signaling exchange between the second-class user terminals and a network can be further reduced, the power consumption of the second-class user terminals is effectively reduced, and the problem of high power consumption of the user terminals caused by the fact that all the user terminals based on the same-vehicle scene need to perform measurement report in the related technology is solved.
Specifically, referring to fig. 3, an interaction schematic diagram of a cell measurement control method provided in an embodiment of the present invention is shown, and in this embodiment, the method includes the following steps:
step S01: the core network equipment identifies the user terminals of the same vehicle and divides the user terminals into a first type of user terminals and a second type of user terminals.
Before this, all the user terminals send RRC connection reconfiguration complete messages to the source base station, and all the user terminals measure the signal strengths of the current cell and the neighboring cell and report the measurement results to the source base station.
Step S02: and the core network equipment sends a measurement report stopping indication message to the second type user terminal.
Step S03-04: the second type of user terminal stops measurement reporting to save power consumption, and only the first type of user terminal performs measurement reporting at this time.
Step S05: the source base station triggers a handover decision.
Because the locations are very close, the signal strengths of all the first-class user terminals are similar, and the source base station may trigger the handover decision when all the first-class user terminals need to be handed over, or may trigger the handover decision when the first-class user terminals higher than a certain threshold (for example, 80%) need to be handed over.
Step S06: the source base station informs the target base station to prepare for handover.
Specifically, the information carries the identity information of all the first class user terminals, so that the target base station reserves resources for the first class user terminals.
Step S07: and the target base station sends a second type user terminal information acquisition request to the core network equipment.
Step S08: and the core network equipment sends the identity identification information of all the second type user terminals to the target base station.
Step S09: and the target base station informs the source base station that the preparation of switching between the first type user terminal and the second type user terminal is completed.
Specifically, the target base station prepares radio resources for the first class of user terminals and the second class of user terminals, and sends cell admission completion messages of all the first class of user terminals and the second class of user terminals to the source base station.
Step S10: and the source base station sends RRC connection reconfiguration information to all the user terminals in the same vehicle, and informs the first type of user terminals and the second type of user terminals of the information of the target cells.
Step S11: the first type user terminal and the second type user terminal are accessed into the target cell and send RRC connection reconfiguration finishing messages to the target cell.
Step S12: and the source base station releases resources.
The invention reduces the power consumption by regarding the passengers of the same high-speed rail or the same passenger car as the same class of users, selecting some users (first class users) from the core network to carry out normal measurement reporting and switching signaling interaction, and informing other users (second class users) that the measurement reporting is not needed. When the cell switching is needed, the target base station acquires the information of the second type of users from the core network and prepares resources for the second type of users. And the target base station sends cell access completion messages of all the first-class users and the second-class users to the source base station, and the source base station sends RRC connection reconfiguration messages to all the first-class users and the second-class users to carry out cell switching. Therefore, the signaling exchange between the user and the network under the scenes of a 5G network high-speed railway, a high-speed passenger car and the like can be effectively reduced, the power consumption of the user terminal is effectively reduced, the switching time delay is reduced, and the switching success rate is increased.
