The cell reselection method provided by the present application is implemented based on the architecture shown in fig. 1.
Example one
An embodiment of the present application provides a cell reselection method, and as shown in fig. 2, the method may include:
s101, when the current cell enters an idle state, acquiring the priority of the current cell and the priority of an adjacent cell from network side equipment.
An application scenario of the cell reselection method provided by the embodiment of the present invention may be as follows: in the process of moving, when a current cell enters an idle state, a terminal (i.e., UE) needs to perform cell reselection.
It should be noted that, in the idle state, the terminal selects a best cell to provide a service signal by monitoring the signal quality of the neighboring cell and the current cell.
When the signal quality and the level of the adjacent cell meet the S criterion and meet a certain reselection judgment criterion, the terminal accesses the adjacent cell to reside, and the process of cell reselection is realized after the terminal resides in the adjacent cell and stays for a period of time.
The current cell in the embodiment of the present application refers to a cell in which the terminal currently resides, and after the terminal resides in the current cell for a period of time, for example, 1s, the terminal may perform a cell reselection process. The cell reselection process may include two parts, measurement and reselection, and the terminal initiates a corresponding process when a condition is satisfied according to a relevant parameter configured by the network.
It should be noted that, preferably, the network environment implemented by the embodiment of the present invention may be an LTE network.
For an LTE system, a network side device may configure priorities of different frequency points or frequency groups, and inform a terminal in a system message through broadcasting, for example, the priority of a cell is represented by a cell reselection priority parameter, a value may be 0-7, and the priority of inter-frequency cell reselection is a value between 0 and 7, where 0 represents the lowest priority. In general, the priority of the inter-system 2G is 1, the priority of the 3G is 2, and the priority of the 4G is 3(F band: 38400, 38404, 38350), 5(D band: 37900, 38098), and 7(E band: 38950, 39148), which are not limited in this embodiment. That is to say, when the current cell enters the idle state, the terminal acquires the priority of the current cell and the priority of the neighboring cell from the network side device, so that the subsequent terminal can make a measurement and reselection decision based on the priority of the current cell and the priority of the neighboring cell. The system message carries neighbor information.
Further, the terminal may further acquire the information related to the priority through an RRC connection release message.
It should be noted that if the dedicated priority is provided in the system message, the terminal will ignore all the common priorities. If the priority of the cell where the terminal currently resides is not provided in the system message, the terminal sets the priority of the frequency point where the current cell is located to be the lowest. And the terminal performs cell reselection according to the priority strategy only among the frequency points which appear in the system message and provide the priority.
Optionally, the terminal in the embodiment of the present invention may be an electronic device with a wireless communication function, for example, a mobile phone, a tablet, and the like, which is not limited in the embodiment of the present application.
In the embodiment of the present application, when the terminal covers the whole cell well, the terminal is usually in a situation that 2-3 cells (i.e. multiple cells) cover simultaneously when moving. Therefore, when the terminal enters an idle state in the current cell, the cell reselection can be carried out.
In the embodiment of the present application, a terminal mainly aims at a scenario of cell reselection in a pilot frequency cell.
S102, performing reselection measurement based on the priority of the current cell and the priority of the adjacent cell to obtain a first measurement parameter of the adjacent cell.
After the terminal acquires the priority of the current cell and the priority of the adjacent cell, the terminal can determine the starting of the measurement of the adjacent cell, namely perform reselection measurement, based on the priority of the current cell, the priority of the adjacent cell and the measurement judgment condition, so as to obtain the first measurement parameter of the adjacent cell.
It should be noted that the measurement may include: co-frequency measurement and inter-frequency measurement. Wherein, the same frequency measurement is to measure the downlink frequency point of the adjacent cell which is the same as the downlink frequency point of the current cell. The pilot frequency measurement is to measure a downlink frequency point (same cell or adjacent cell) different from the downlink frequency point of the current cell.
In the embodiment of the present application, a scenario in which a terminal mainly aims at a different-frequency cell to implement handover is provided, and therefore, the terminal aims at different-frequency measurement.
In the embodiment of the application, the terminal continuously performs the current cell measurement after the current cell is successfully camped. And the terminal calculates Srxlev (S criterion) (named as a first measurement parameter in the embodiment of the present application) according to the RSRP measurement result (different from the meaning of the first measurement parameter in the embodiment of the present application) through a Radio Resource Control protocol (RRC) layer, and compares the rsxlev (S criterion) (named as the first measurement parameter in the embodiment of the present application) with Sintrasearch (same frequency measurement start threshold) and Snonintrasearch (different frequency/different system measurement start threshold) after comparing based on the priority, and the comparison is used as a judgment condition for whether to start the neighbor measurement. Here, Srxlev is the RSRP value of the measurement cell (current cell) { lowest reception level (typically 0-128dbm) + lowest reception level offset (typically 0) } -power offset (typically 0). Snonintrasearch is also carried in the system message broadcast.
The terminal mainly aims at the inter-frequency cell to realize the cell reselection scene, so the terminal can determine the measurement of the adjacent cell according to the second measurement parameter and Snonintrasearch of the current cell.
The measurement decision conditions in the embodiment of the present application are:
1. when the priority of the adjacent cell is higher than that of the current cell, the terminal performs measurement on the adjacent cell;
2. when the priority of the adjacent cell is lower than that of the current cell, if the Srxlev value of the current cell is less than or equal to Snoninthasearch, measuring the adjacent cell; and if the Srxlev value of the current cell is larger than Snoninthasearch, starting the neighbor cell measurement.
Further, when Snonintrasearch is not carried in the system message broadcast, inter-frequency cell measurement (measurement of inter-frequency neighbor cells) can also be started.
Therefore, after the terminal is based on the measurement judgment, when the neighbor cell measurement is started, the first measurement result of the neighbor cell can be obtained, and then the first measurement parameter is obtained through calculation.
S103, determining the bandwidth of the adjacent cell based on the preset network deployment information.
In the embodiment of the application, the terminal stores preset network deployment information in advance, and the mapping relationship between the position represented by the preset network deployment information and the bandwidth of the adjacent cell is obtained based on historical measurement statistics of the terminal. The specific process can be as follows:
acquiring historical measurement records and historical position information;
analyzing the bandwidth of the historical adjacent cell corresponding to the historical position information from the historical measurement record;
and taking the corresponding relation between the historical position information and the bandwidth of the historical adjacent cell as the preset network deployment information.
In this way, the terminal deploys information based on the preset network, and since the terminal knows the neighbor cell information from the system message of the network side device in the above process, the process that the terminal can determine the bandwidth of the neighbor cell corresponding to the neighbor cell information may include: and S1031-1032. The following were used:
and S1031, obtaining the current position information.
S1032, obtaining the bandwidth of the adjacent cell corresponding to the current position information from the preset network deployment information.
The terminal can acquire the current position information of the terminal through a positioning function or a notification of a base station, and the preset network deployment information is the corresponding relation between the historical position information and the bandwidth of the historical adjacent cell, so that the terminal can acquire the bandwidth of the adjacent cell corresponding to the terminal at the moment from the preset network deployment information as long as the current position of the terminal is the place where the terminal has come before. Thus, after the terminal acquires the preset network deployment information, the terminal can determine the bandwidth of the neighboring cell at the current position based on the preset deployment information.
The location information may be a place name, a longitude and latitude, or a location represented by a cell coverage, and the like, which is not limited in the embodiment of the present application.
It should be noted that in the practical process, a scenario with a small bandwidth may occur due to network deployment of an operator, for example, Band3 and Band8 supported by a mobile operator are only 5M, and Band5 supported by a telecommunications operator is only 3M and 5M, so that when a terminal reselects a cell with a small bandwidth to perform service processing, because the bandwidth is small, the number of resources allocated to the terminal by a wireless network is small, and thus, a stuck phenomenon occurs due to transmission delay when the terminal performs service processing or service data transmission on the allocated resources or frequency bands. Therefore, in the embodiment of the present application, it is determined whether the neighboring cell is a cell with a small bandwidth or not according to the motion trajectory of the user, that is, the current location information, and some different cell reselection processes are performed on the cell with the small bandwidth.
And S104, when the current connection is normal and the bandwidth of the adjacent cell meets the lower limit value of the preset bandwidth, increasing a preset offset to the preset reselection threshold to obtain an adjusted preset reselection threshold.
And S105, determining the resident cell based on the adjusted preset reselection threshold value and the first measurement parameter.
After the terminal acquires the first measurement parameter and the bandwidth of the adjacent cell, when the current connection is normal and the adjacent cell is the cell with the small bandwidth (meeting the preset lower bandwidth limit range), the terminal enters a reselection part, adjusts the preset reselection threshold value for performing reselection judgment on the second measurement parameter, increases a preset offset to the preset reselection threshold value, increases the difficulty of successful reselection judgment, and thus obtains the adjusted preset reselection threshold value.
The preset lower limit of the wideband is a bandwidth range of a small bandwidth, for example, 3M to 5M, and the preset lower limit of the wideband may be a continuous range value or at least one value, which is not limited in the embodiments of the present application.
It should be noted that, in this embodiment of the present application, a premise that the terminal may reselect the cell with good signal quality but small bandwidth in a delayed manner is that a connection status of a current cell of the terminal is normal enough to continuously support that the terminal can implement service data transmission in the current cell. That is, before adjusting the preset reselection threshold, the terminal needs to perform the following process:
and S106, detecting the connection state with the service server to obtain the running information.
And S107, when the operation information represents that the service data transmission is normal, detecting that the current connection is normal.
And S108, when the operation information represents that the service data transmission is abnormal, detecting that the current connection is abnormal.
The terminal tests the connection status of the service data server at the user side, tests parameters (operation information) such as PING or packet loss rate, namely detects the connection state with the service server, and thus obtains the operation information. The terminal can know whether the service data can be normally transmitted or not through the operation information, and then determines whether the current connection state is normal or not, namely when the operation information represents that the service data is normally transmitted, the terminal detects that the current connection is normal (enough to support service processing); when the operation information represents that the service data transmission is abnormal, the terminal detects that the current connection is abnormal (the current connection is not enough to support the service processing). When the current connection is normal, the terminal can improve the difficulty of cell reselection and reselect the neighboring cell with small bandwidth in a delayed manner. When the current connection is abnormal, the terminal performs the existing reselection process to realize cell reselection.
It should be noted that when the terminal acquires the second measurement parameter, the terminal starts to perform reselection judgment, but the terminal increases a threshold on a preset reselection threshold value, which increases the difficulty of reselection judgment, so as to avoid a situation that a user wants to perform traffic data transmission and is stuck when the terminal reselects a neighboring cell with a small bandwidth.
In the embodiment of the present application, the preset offset is a positive number.
After the terminal increases the preset offset from the preset reselection threshold, it may determine whether the reselection decision condition is satisfied according to the new reselection threshold, that is, the preset reselection threshold. That is, the terminal may determine whether the reselection decision satisfies the reselection criterion based on adjusting the preset reselection threshold value and the first measurement parameter, and the reselection decision condition (i.e., the reselection criterion), thereby determining the camping cell where the terminal is to camp on.
Further, the terminal determines that the priority of the current cell and the priority of the neighboring cell need to be used in the process of residing in the cell based on adjusting the preset reselection threshold value and the first measurement parameter.
In the embodiment of the present application, the reselection decision condition is:
when the priority of the adjacent cell is higher than that of the current cell and the first measurement parameter is less than or equal to the preset reselection threshold value, determining that the current cell is the resident cell;
and when the priority of the adjacent cell is higher than that of the current cell and the first measurement parameter is continuously larger than the adjusted preset reselection threshold value within the first preset time, determining that the adjacent cell is the resident cell.
For example, when a cell reselection at a high priority frequency point (i.e. when the priority of a neighboring cell is high), that is, a terminal wants to reselect a neighboring cell camped on a high priority frequency point, the following conditions need to be satisfied:
the time for the UE to reside in the current cell exceeds 1 s; the Srxlev value (obtained based on the first measurement parameter) of the high-priority frequency cell is greater than a preset threshold (ThreshXHigh: high-priority reselection threshold) + a preset offset custom offset (i.e., the preset reselection threshold is adjusted), and the duration exceeds a reselection time parameter T (first preset time).
Otherwise, the Srxlev value of the high-priority frequency point cell is less than or equal to a preset threshold (ThreshXHigh: high-priority reselection threshold) + a preset offset custom offset, and the terminal continuously resides in the current cell, so that the delay reselection is realized.
It can be understood that, in the process of terminal movement, when the current cell of the terminal enters an idle state, and when a network side device (base station) triggers a reselection process, because the terminal can determine whether the neighboring cell belongs to a cell with a small bandwidth (meeting a bandwidth within a preset bandwidth lower limit) on the premise that the current cell still has enough service data processing (i.e., the current connection is normal), by increasing a value of a trigger reselection decision threshold (adjusting a preset reselection threshold value), the difficulty of reselection decision is increased, and the reselection process is delayed, the purpose of delaying the cell reselection process can be achieved, thereby avoiding delay and stuttering of data transmission when the cell with the small bandwidth is reselected, and improving the real-time performance of data transmission and further improving the performance of the terminal under the condition that the current cell can support service data.
Example two
An embodiment of the present application provides a cell reselection method, and as shown in fig. 3, the method may include:
s201, when the current cell enters an idle state, acquiring the priority of the current cell and the priority of an adjacent cell from network side equipment.
In this embodiment of the present application, a process of acquiring the priority of the current cell and the priority of the neighboring cell from the network side device when the current cell enters the idle state is consistent with the description of S101 in the first embodiment, and is not described herein again.
S202, based on the priority of the current cell and the priority of the adjacent cell, reselection measurement is carried out to obtain a first measurement parameter of the adjacent cell, and the current cell is measured to obtain a second measurement parameter of the current cell.
After the terminal acquires the priority of the current cell and the priority of the adjacent cell, the terminal can determine the starting of the measurement of the adjacent cell, namely perform reselection measurement, based on the priority of the current cell, the priority of the adjacent cell and the measurement judgment condition, so as to obtain the first measurement parameter of the adjacent cell.
It should be noted that the measurement may include: co-frequency measurement and inter-frequency measurement. Wherein, the same frequency measurement is to measure the downlink frequency point of the adjacent cell which is the same as the downlink frequency point of the current cell. The pilot frequency measurement is to measure a downlink frequency point (same cell or adjacent cell) different from the downlink frequency point of the current cell.
In the embodiment of the present application, a scenario in which a terminal mainly aims at a different-frequency cell to implement handover is provided, and therefore, the terminal aims at different-frequency measurement.
In the embodiment of the application, the terminal continuously performs the current cell measurement after the current cell is successfully camped. And the terminal calculates Srxlev (S criterion) according to the RSRP measurement result through a Radio Resource Control protocol (RRC) layer, compares the RSRP measurement result with Sintrasearch (same frequency measurement starting threshold) and Snonitrasearch (different frequency/different system measurement starting threshold) after the priority comparison, and takes the comparison as a judgment condition for judging whether to start the neighbor measurement. Here, Srxlev is the RSRP value of the measurement cell (current cell) { lowest reception level (typically 0-128dbm) + lowest reception level offset (typically 0) } -power offset (typically 0). Snonintrasearch is also carried in the system message broadcast.
The terminal mainly aims at the inter-frequency cell to realize the cell reselection scene, so the terminal can determine the measurement of the adjacent cell according to the second measurement parameter and Snonintrasearch of the current cell.
That is, when performing reselection measurement based on the priority of the current cell and the priority of the neighboring cell to obtain the first measurement parameter of the neighboring cell, the terminal has already measured the current cell to obtain the second measurement parameter of the current cell.
The measurement decision conditions in the embodiment of the present application are:
1. when the priority of the adjacent cell is higher than that of the current cell, the terminal performs measurement on the adjacent cell;
2. when the priority of the adjacent cell is lower than that of the current cell, if the Srxlev value of the current cell is less than or equal to Snoninthasearch, measuring the adjacent cell; and if the Srxlev value of the current cell is larger than Snoninthasearch, starting the neighbor cell measurement.
Further, when Snonintrasearch is not carried in the system message broadcast, inter-frequency cell measurement (measurement of inter-frequency neighbor cells) can also be started.
Thus, after the terminal is based on the measurement judgment, when the neighboring cell measurement is started, the first measurement parameter of the neighboring cell can be obtained.
S203, determining the bandwidth of the adjacent cell based on the preset network deployment information.
In this embodiment of the present application, a process of "determining a bandwidth of an adjacent cell based on preset network deployment information" is consistent with the description of S103 in the first embodiment, and is not described herein again.
And S204, when the current connection is normal and the bandwidth of the adjacent cell meets the lower limit value of the preset bandwidth, increasing a preset offset to the preset reselection threshold to obtain an adjusted preset reselection threshold.
S205, determining the resident cell based on the adjustment of the preset reselection threshold value, the first measurement parameter and the second measurement parameter.
After the terminal acquires the first measurement parameter, the second measurement parameter and the bandwidth of the adjacent cell, when the current connection is normal and the adjacent cell is a cell with a small bandwidth (meeting a preset lower limit range), the terminal enters a reselection part, a preset reselection threshold value for performing reselection judgment on the second measurement parameter is adjusted, a preset offset is added to the preset reselection threshold value, the difficulty of success reselection judgment is increased, and the adjusted preset reselection threshold value is obtained.
The preset lower limit of the wideband is a bandwidth range of a small bandwidth, for example, 3M to 5M, and the preset lower limit of the wideband may be a continuous range value or at least one value, which is not limited in the embodiments of the present application.
It should be noted that, in this embodiment of the present application, a premise that the terminal may reselect the cell with good signal quality but small bandwidth in a delayed manner is that a connection status of a current cell of the terminal is normal enough to continuously support that the terminal can implement service data transmission in the current cell. That is, before adjusting the preset reselection threshold, the terminal needs to perform the following process:
and S106, detecting the connection state with the service server to obtain the running information.
And S107, when the operation information represents that the service data transmission is normal, detecting that the current connection is normal.
And S108, when the operation information represents that the service data transmission is abnormal, detecting that the current connection is abnormal.
The terminal tests the connection status of the service data server at the user side, tests parameters (operation information) such as PING or packet loss rate, namely detects the connection state with the service server, and thus obtains the operation information. The terminal can know whether the service data can be normally transmitted or not through the operation information, and then determines whether the current connection state is normal or not, namely when the operation information represents that the service data is normally transmitted, the terminal detects that the current connection is normal (enough to support service processing); when the operation information represents that the service data transmission is abnormal, the terminal detects that the current connection is abnormal (the current connection is not enough to support the service processing). When the current connection is normal, the terminal can improve the difficulty of cell reselection and reselect the neighboring cell with small bandwidth in a delayed manner. When the current connection is abnormal, the terminal performs the existing reselection process to realize cell reselection.
It should be noted that when the terminal acquires the first measurement parameter and the second measurement parameter, the terminal starts to perform reselection judgment, but the terminal increases a threshold on a preset reselection threshold value, which increases the difficulty of reselection judgment, so as to avoid occurrence of a stuck condition in the service data transmission when the terminal reselects a small-bandwidth neighboring cell.
In the embodiment of the present application, the preset offset is a positive number.
After the terminal increases the preset offset from the preset reselection threshold, it may determine whether the reselection decision condition is satisfied according to the new reselection threshold, that is, the preset reselection threshold. That is, the terminal may determine whether the reselection decision satisfies the reselection criterion, based on adjusting the preset reselection threshold value, the first measurement parameter and the second measurement parameter, and the reselection decision condition (i.e., the reselection criterion), so as to determine the camping cell where the terminal is to camp on.
Further, the terminal determines that the priority of the current cell and the priority of the neighboring cell need to be used in the process of residing in the cell based on adjusting the preset reselection threshold value, the first measurement parameter and the second measurement parameter.
In the embodiment of the present application, the reselection decision condition is:
when the priority of the adjacent cell is smaller than that of the current cell and the first measurement parameter is smaller than or equal to the preset reselection threshold value, determining that the current cell is a resident cell;
when the priority of the adjacent cell is smaller than the priority of the current cell and the second measurement parameter is greater than or equal to a low-priority reselection threshold of a preset serving cell, determining that the current cell is a resident cell;
and when the priority of the adjacent cell is smaller than the priority of the current cell, the first measurement parameter is continuously larger than the adjustment preset reselection threshold value within a second preset time, and the second measurement parameter is smaller than the low-priority reselection threshold value of the preset service cell, determining that the adjacent cell is the resident cell.
For example, when a cell reselection at a low priority frequency point (i.e. when the priority of a neighboring cell is low), that is, a terminal wants to reselect a neighboring cell camped on a low priority frequency point, the following conditions need to be satisfied:
the time for the UE to reside in the current cell exceeds 1 s; the cell without the high-priority frequency point meets the reselection requirement condition; the Srxlev value of the low-priority frequency point cell (obtained based on the first measurement parameter) is smaller than a preset threshold (ThreshXlow: low-priority reselection threshold) + a preset offset custom offset (i.e. the preset reselection threshold is adjusted), and the duration exceeds a reselection time parameter M (second preset time), and the Srxlev value of the high-priority frequency point cell (obtained based on the second measurement parameter) is larger than a preset serving cell low-priority reselection threshold. Wherein, M may be the same as or different from T in the first embodiment, and the embodiment of the present application is not limited.
Otherwise, the terminal can continue to camp on the current cell if at least one of the following conditions is met.
The Srxlev value (first measurement parameter) of the low-priority frequency point cell is greater than or equal to a preset threshold (ThreshXlow: low-priority reselection threshold) + a preset offset custom offset (i.e. adjusting the preset reselection threshold), and the terminal continues to reside in the current cell, thereby realizing the delay reselection.
And the Srxlev value (second measurement parameter) of the high-priority frequency point cell is less than or equal to the low-priority reselection threshold of the preset service cell, and the terminal continuously resides in the current cell, so that the delayed reselection is realized.
It can be understood that, in the process of terminal movement, when the current cell of the terminal enters an idle state, and when a network side device (base station) triggers a reselection process, because the terminal can determine whether the neighboring cell belongs to a cell with a small bandwidth (meeting a bandwidth within a preset bandwidth lower limit) on the premise that the current cell still has enough service data processing (i.e., the current connection is normal), by increasing a value of a trigger reselection decision threshold (adjusting a preset reselection threshold value), the difficulty of reselection decision is increased, and the reselection process is delayed, the purpose of delaying the cell reselection process can be achieved, thereby avoiding delay and stuttering of data transmission when the cell with the small bandwidth is reselected, and improving the real-time performance of data transmission and further improving the performance of the terminal under the condition that the current cell can support service data.
