Description
Technical Field
The embodiments of the present invention relate to, but are not limited to, the field of communications technologies, and in particular, but not limited to, a method, an apparatus, a terminal, and a computer-readable storage medium for cell handover of a base station
Background
At present, the experience of mobile communication users on high-speed rails is not good all the time. The following pain points prevail: (1) signals on some lines and road sections of high-speed rails are not good, so that the mobile phone is disconnected; (2) the mobile phone needs to frequently find a network on a high-speed rail, and uses high-data-rate applications, such as frequent jamming like video; (3) the mobile phone consumes fast power. Causes of these phenomena include:
reason 1: the speed of the high-speed rail is very fast, the speed is 50-100 meters per second, only 10 seconds are needed for traversing a space of 1 kilometer, and along the high-speed rail, the coverage area of a mobile communication base station is small and 500 meters are large and is less than 2 kilometers (4G LTE, if 5G, the distance is closer); this means that the mobile terminal on the train needs to make a cell handover in less than 10 seconds, and the handover is so frequent that the continuity of the data service is necessarily interrupted. On some road segments, the terminal is constantly in frequent signaling handover.
Reason 2: the high-speed rail is covered by a network along the line, the base station of the public network and the base station of the high-speed rail private network exist, due to the high-speed moving characteristic of the high-speed rail, radio frequency signals sent by a terminal can generate Doppler frequency shift dominance when the base station side receives the radio frequency signals, and therefore the base station of the high-speed rail private network can perform special processing. But the terminal on the train may try to connect to the base station of the public network. The frequent switching of the mobile phone between the high-speed rail private network base station and the public network base station can cause the mobile phone signal to be unstable and to be disconnected.
Reason 3: the high-speed railway carriage is a metal covering, and radio waves of the mobile terminal are transmitted out, so that great attenuation is caused, and the transmission power of a mobile phone is increased for effective receiving of the terminal. In addition, the power consumption is continuously improved in the process of finding the network, so that the power consumption of the mobile phone is increased, and the mobile phone consumes fast power.
At present, in order to solve the user experience problems, generally adopted methods mainly include:
the method comprises the following steps: the mobile phone increases a high-speed rail mode, and in the high-speed rail mode, the mobile phone increases the power consumption of receiving and sending. The scheme can compensate for signal attenuation caused by carriage skin, but the improvement effect on frequent network searching and invalid connection is not large, and the power consumption of the mobile phone is increased.
The second method comprises the following steps: base station data information along a high-speed rail is preset on the terminal, and when the terminal moves along with a train, the base station information in the advancing direction can be acquired according to the current position, so that the priority is improved, and switching preparation is made. Theoretically, the method can greatly reduce unnecessary signal interference of the non-preset base station, and also reduces unnecessary work of searching available networks nearby, measuring and comparing base station signals and the like; therefore, the efficiency of mobile phone connection and cell switching is ensured. This scheme can reduce interference from non-subscribing base stations, but is difficult to implement. High-speed rail network construction and network optimization are carried out at any time, and base station data are quite huge and can be changed. With this scheme, the data information maintenance cost is considerable, and once the preset base station data information is wrong, the side effect is that the connection is dropped.
Therefore, how to provide a better method for switching base station cells in a high-speed moving scene is an urgent problem to be solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
in order to solve the problems of high call drop rate, high reestablishment rate and high power consumption of a terminal in a high-speed mobile scene, referring to fig. 1, an embodiment of the present invention provides a base station cell switching method, including:
s101: and when the terminal is in a high-speed rail mode, determining that the base station cell of the high-speed rail mobile network meeting the preset residence condition exists in the adjacent cell.
S102: and if the terminal is not resident in the base station cell of the high-speed rail mobile network at present, controlling the terminal to be switched to the base station cell of the high-speed rail mobile network.
The embodiment of the invention is suitable for occasions with mobile base stations on high-speed rails, for example, the base stations of a mobile communication network are installed on a high-speed rail train, and each carriage or a plurality of carriages can share one micro base station according to requirements. It can be understood that, in this application scenario, the base station cells where the terminal can camp include: a base station cell of a high-speed rail mobile network, a base station cell of a high-speed rail private network and a base station cell of a public network.
Through the steps S101 and S102, the terminal can be preferentially connected with the base station cell of the high-speed rail mobile network, and the terminal always resides in the base station cell of the high-speed rail mobile network when the base station cell of the high-speed rail mobile network meets the preset residence condition. Therefore, the network communication quality of the terminal is effectively improved, the problems of frequent network searching and switching of the terminal are avoided, the internet access consistency of the terminal is ensured, and the power consumption of the terminal is also reduced.
Before the above steps, it is also necessary to determine whether the terminal is in the high-speed rail module. Ways for determining that the terminal is in the high-speed mode include, but are not limited to, the following:
the first method is as follows:
in some embodiments, the method further comprises, prior to: and detecting the cell information of the adjacent cell according to a preset period, and determining that the terminal is in a high-speed rail mode according to the cell information of the adjacent cell.
In some embodiments, the cell information of the detected neighboring cell per period includes: presetting a preset number of base station cell identification information;
the determining that the terminal is in a high-speed rail mode according to the cell information of the neighboring cell comprises:
and acquiring cell information of the neighbor cells detected in a plurality of current periods, and determining that the terminal is in a high-speed rail mode when the number of the different base station cell identification information in the two adjacent periods reaches a preset number threshold value.
It should be noted that the cell information of the neighboring cell detected in each period includes a plurality of pieces of base station cell information, such as base station cell identification information and signal measurement values of the base station cell. The Signal measurement value of the base station cell refers to parameters such as RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio), and the like. And the terminal is provided with a neighbor cell list for storing the received cell information of the neighbor cells. And the terminal acquires the cell information of the nearby base station according to a preset search period and ensures the acquired cell information of the base station in a neighbor cell list. For example, several (including but not limited to 50, 100, 200) recently received nearby base station cell information and received time information are stored in the neighbor list. The information stored in the neighbor list can be used to determine whether the terminal is in a high-speed rail mode. For example, the terminal may obtain information of 5 base station cells in each search period, and update the neighbor cell list according to the obtained information of the base station cells. Then, the base station cell identification information obtained in the last continuous 10 periods can be extracted from the neighbor cell list, whether the same base station cell identification information is obtained in the two adjacent periods is judged, and if 3 or more different base station cell identification information exists in each two adjacent periods in the 10 periods, it can be determined that the terminal is in the high-speed railway mode. In some scenarios, when the terminal is in the high-speed rail mode, the same base station cell identification information is acquired in all of the 10 periods, and at this time, the same base station cell can be considered as the base station cell of the high-speed rail mobile network.
The second method comprises the following steps:
in some embodiments, when it is determined that the base station cell of the high-speed rail mobile network exists in the neighboring cell according to the identification information of the base station cell of the high-speed rail mobile network, the terminal is in a high-speed rail mode.
It can be understood that the base station cells of the high-speed rail mobile network have special identification information, and the terminal can directly identify the base station cells of the high-speed rail mobile network. In this way, the terminal determines the base station cell of the nearby high-speed rail mobile network, so as to obtain that the terminal is in a high-speed rail mode.
The third method comprises the following steps:
the terminal inquires whether the user is in the high-speed rail mode or not through a pop-up prompt interface, and then determines whether the terminal is in the high-speed rail mode or not according to feedback information of the user. For example, the prompt interface that the terminal can pop up includes query information of "whether the terminal is in the high-speed rail mode" and selection keys of "yes" and "no", and when the terminal detects that the user clicks "yes", it is determined that the terminal is in the high-speed rail mode.
In some embodiments, the controlling the terminal to switch to the base station cell of the high-speed rail mobile network further comprises:
and stopping acquiring the base station cell information of the adjacent cell when the base station cell of the high-speed rail mobile network is determined to meet the preset measurement optimization condition.
It can be understood that, in order to further optimize unnecessary network measurements on the terminal and reduce power consumption of the terminal, a preset measurement optimization condition may be added. Specifically, whether the signal measurement value of the base station cell of the high-speed rail mobile network reaches a preset measurement threshold is judged, and if yes, it is determined that the base station cell of the high-speed rail mobile network meets a preset measurement optimization condition. The signal quality of the base station cell of the high-speed rail mobile network is good, and the terminal can be locked in the base station cell of the high-speed rail mobile network for a long time; at this time, the terminal does not measure signals of the neighbor cells any more to reduce unnecessary power consumption. In addition, if the signal measurement value of the base station cell of the high-speed rail mobile network is between the preset residence threshold and the preset measurement threshold, the terminal keeps measuring the signals of the adjacent cells. If a plurality of base station cells to be measured around the cell are detected, the signal of only one of the base station cells can be measured. Meanwhile, the obtained signal measurement value of the base station cell is not reported, and the base station cell is used as an alternative and can be switched when the base station cell where the terminal resides is abnormal.
In some embodiments, the controlling the terminal to switch to the base station cell of the high-speed rail mobile network further comprises:
and determining that the base station cell of the high-speed rail mobile network does not meet the preset residence condition, and controlling the terminal to be switched to the base station cell of the high-speed rail private network when the base station cell of the high-speed rail private network meeting the preset residence condition exists in the adjacent cell.
Specifically, the signal measurement value of the base station cell of the current high-speed rail mobile network is lower than the preset residence threshold, and other types of base station cells meeting the preset residence condition exist around the current high-speed rail mobile network, such as the base station cell of a high-speed rail private network and the base station cell of a public network. At this point, a base station cell handover may be initiated to camp on the terminal in other types of base station cells. In addition, after the terminal resides in other types of base station cells, whether the current terminal is in a high-speed rail mode can be further judged. If yes, it indicates that there is a stable available base station cell of the high-speed rail mobile network around, and then the base station cell residing in the high-speed rail mobile network can be made.
In some embodiments, the controlling the terminal to switch to the base station cell of the high-speed rail private network further comprises:
and when the base station cell of the high-speed rail mobile network meeting the preset residence condition is not detected in the adjacent cell within the preset time period, controlling the terminal to exit the high-speed rail mode.
Specifically, if the base station cell of the high-speed rail mobile network which is stably available is not found for a while, indicating that the base station cell of the high-speed rail mobile network is inaccessible, the terminal exits the high-speed rail mode. And when the terminal is in a non-high-speed rail mode, the terminal can be connected with a base station cell of a high-speed rail private network or a base station cell of a public network according to a default network protocol.
Example two:
for better understanding of the present invention, an embodiment of the present invention provides a method for switching a cell of a base station in a specific application scenario, please refer to fig. 2, where the method includes the following steps:
s201: the train starts to accelerate and the terminal is in a non-high-speed rail mode.
When the train is not started or starts to accelerate, the terminal is in a non-high-speed railway mode, and the terminal is connected to a suitable available base station cell according to a default network protocol. The terminal may be connected to a base station cell of a public network, or a base station cell of a high-speed rail private network, or a base station cell of a high-speed rail mobile network at this time.
S202: and when the speed of the train reaches a preset speed threshold value, triggering the terminal to judge the high-speed railway mode.
When the train speed reaches a preset speed threshold value, the change value of the base station cell information received by the terminal reaches a preset value, for example, when new base station cell information is added into a neighbor list in 10 seconds, a high-speed rail mode judgment program is triggered.
S203: the terminal is in high-speed rail mode.
The first method is as follows: if the base station cell information of the high-speed rail mobile network has the special identification, the terminal directly identifies the base station cell of the high-speed rail mobile network, and the terminal can directly switch the current network scene into a high-speed rail mode.
The second method comprises the following steps: if the base station cell information of the high-speed rail mobile network has no special identifier, the base station cell identifier information acquired in the last continuous 10 periods can be read from the neighbor cell list, and the 10 periods all acquire the same base station cell identifier information (the base station cell can be regarded as the base station cell of the high-speed rail mobile network), and 3 or more different base station cell identifier information exist in the adjacent two periods, the terminal switches the current network scene to be in the high-speed rail mode.
In addition, if the current terminal does not satisfy any of the above situations, the terminal keeps the current network connection mode and is still in the non-high-speed rail mode.
S204: whether or not to camp on a base station cell of a high-speed rail mobile network.
After the network scene of the terminal is switched to a high-speed rail mode, checking whether a base station cell where the terminal resides currently is a base station cell of a high-speed rail mobile network, if not, executing S205, namely switching the terminal to the base station cell of the high-speed rail mobile network; if yes, go to step S206.
S205: and switching to the base station cell of the high-speed rail mobile network.
If the specified measured neighbor cell has the base station cell of the high-speed rail mobile network in the reconfiguration message of the base station received by the current terminal, measuring the signal quality of the base station cell of the high-speed rail mobile network, and if the signal measurement value of the base station cell of the high-speed rail mobile network meets the switching condition, reporting the signal measurement value of the base station cell of the high-speed rail mobile network, so that the terminal is switched to the base station cell of the high-speed rail mobile network.
S206: whether a preset stay condition is satisfied.
After the terminal resides in a base station cell of a high-speed rail mobile network, judging whether a signal measurement value of the base station cell of the high-speed rail mobile network reaches a preset residence threshold; if yes, go to step S207, and stay in the base station cell of the high-speed rail mobile network; otherwise, S301 is executed.
S207: and the terminal is locked in a base station cell of the high-speed rail mobile network.
S208: whether a preset measurement optimization condition is met.
Whether the signal measurement value of the high-speed rail mobile network where the terminal currently resides reaches a preset measurement threshold or not can be further judged, and if yes, S209 is executed; otherwise, S210 is executed.
S209: the signals of the base station cells in the neighbouring cell are no longer measured.
And if the signal measurement value of the high-speed rail mobile network where the terminal currently resides is higher than a preset measurement threshold, optimizing a base station measurement strategy. Namely, the signal of the base station cell in the adjacent cell is not measured any more, and the measurement result is not reported.
S210: and measuring signals of a small number of base station cells in the adjacent cell.
And if the signal measurement value of the high-speed rail mobile network where the terminal currently resides is between the preset residence threshold and the preset measurement threshold, the terminal responds to the reconfiguration message sent by the base station and measures the signal of the base station cell in the adjacent cell. However, when there are multiple base station cells to be measured at the same time, only the signal of one base station cell is measured, and the measurement result is not reported, and the base station cell is used as an alternative.
S301: whether the reconfiguration message sent by the base station can be received or not.
If the signal measurement value of the base station cell of the high-speed rail mobile network where the terminal currently resides is lower than a preset residence threshold and the current network scene still meets a high-speed rail mode, further judging whether a reconfiguration message issued by the base station cell can be received; if yes, go to S302; otherwise, S303 is executed.
S302: the terminal initiates the handover.
The terminal can receive the reconfiguration message issued by the base station, report the measurement result and initiate the switching.
S303: the network is searched again.
And the terminal can not receive the reconfiguration message sent by the base station, and then searches the network again.
S304: and selecting other base station cells for access.
And when the network is searched again, setting the base station cell of the high-speed rail mobile network to be preferentially selected for access. And if the base station cell of the high-speed rail mobile network in the adjacent cell still does not meet the preset residence condition, and other base station cells (such as the base station cell of the high-speed rail private network or the base station cell of the public network) meet the preset residence condition, selecting other base station cells for access.
S305: whether in high-speed mode.
And after accessing other base station cells, responding to the reconfiguration message sent by the base station cell, measuring the base station cell in the adjacent cell, and refreshing the judgment of the high-speed rail mode according to the received cell information of the adjacent cell. If the judgment result of the high-speed rail mode is yes, the fact that a base station cell of a stable and available high-speed rail mobile network appears in the adjacent cell is indicated, and S204 is repeated; otherwise, S306 is executed.
S306: and exiting the high-speed rail mode.
If the time is kept for a while, no base station cell of the stably available high-speed rail mobile network exists in the adjacent cell, which indicates that the base station cell of the high-speed rail mobile network can not be accessed, and the terminal exits the high-speed rail mode. In the non-high-speed rail mode, the terminal still executes S201 and S202, and the process after S203 is repeated again when the condition is satisfied.
Example three:
in order to solve the problems of high call drop rate, high reestablishment rate and high power consumption of a terminal in a high-speed mobile scene, referring to fig. 3, an embodiment of the present invention provides a network selection apparatus for a terminal, where the apparatus at least includes the following modules:
