The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Fig. 1 shows an application scenario diagram of a terminal signal reselection method applied to an embodiment of the present application. Wherein, the terminal 10 can receive the signals sent by the base stations 11 and 12. When the terminal 10 is powered on, it will receive signals from the surrounding base stations 11 and 12, and search for the cells generated by the base stations 11 and 12. In these cells, the terminal can register on only one cell.
Specifically, the terminal is started, signals are received at several central frequency points where cells may exist, whether the cells may exist around the frequency points is judged according to the received signal strength, and if the terminal stores the frequency points and the operator information when the terminal is shut down last time, the terminal tries on the cells which reside last time after the terminal is started; if not, full-band scanning is carried out in the frequency band range divided to the LTE network, a frequency point with a stronger signal is found to try, and signals are received around the central frequency point. When the terminal stores the frequency point and the operator information during the last shutdown, the terminal stores the information related to the carrier frequency and may also include some cell parameter information. The terminal preferentially selects the cell with the relevant information and judges whether the cell meets the preset criterion of cell selection. Once a suitable cell is present, the terminal selects it and camps on. If none of the cells storing the relevant information is suitable, the terminal will initiate a cell reselection procedure.
The execution main body of the embodiment of the application is a terminal, the terminal is an electronic device with a display screen, and the terminal includes but is not limited to: a smart phone, a handheld device, a personal computer, a tablet computer, an in-vehicle device, a computing device, or other processing device connected to a wireless modem, etc. The terminal devices in different networks may be called different names, for example: user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user equipment, cellular telephone, cordless telephone, Personal Digital Assistant (PDA), terminal equipment in a 5th generation mobile network or future evolution network, and the like. The terminal system is an operating system that can run on the terminal, is a program for managing and controlling terminal hardware and terminal applications, and is an indispensable system application of the terminal. The system comprises but is not limited to Android system, IOS system, Windows Phone (WP) system, Ubuntu mobile version operating system and the like.
Next, a terminal signal reselection method provided by the embodiment of the present application is described with reference to the system architecture of the terminal signal reselection method shown in fig. 1. Fig. 2 schematically illustrates a flow chart of a terminal signal reselection method provided by an embodiment of the present application. As shown in fig. 2, the terminal signal reselection method may include at least the following steps:
s201, acquiring the signal intensity and bandwidth of the current cell and the adjacent cell where the terminal is located.
The terminal mainly relies on two mechanisms for acquiring signals of the current cell and the adjacent cell, one is a location updating mechanism, and the other is a paging mechanism. The bandwidth is used to represent a frequency passband, i.e., the upper and lower limit frequencies that are allowed to pass through the channel.
Specifically, the location update mechanism means that the network knows the geographical location of the terminal, so that the network can find the terminal in an accurate or approximate range. When the terminal is in a connected state (which may be understood as working, such as surfing the internet or talking), since the network knows which cell the terminal is connected to, the paging message can be accurately and directly issued in the cell. When the terminal is in the idle state, the terminal is not physically connected with the network, and the network can only know one approximate position of the terminal, so that the network can only require all base stations in the area to send paging messages when the network wants to page the terminal, and the terminal in the idle state can also receive the paging messages to the maximum extent. The reason why the network in the idle state can only know the approximate range of the terminal is that the terminal in the idle state can only initiate a location update to a new area or after a time exceeding the location update timer, considering that if the terminal initiates a location update each time the terminal moves to a new cell, the generated signaling traffic is too heavy, the network may be too heavy, and the terminal is not favorable for saving power (frequent initiation of the location update to the network consumes more power).
S202, determining a signal strength difference based on the signal strengths of the current cell and the neighboring cell.
The signal strength is used to indicate the strength of the signal, for example, when the unit of the number displayed on the handset is dBm, the value is usually negative, and the larger the value is, the higher the signal strength is, for example, when the signal strength is-50 dBm-0 dBm, the handset may be near the base station, and when the signal strength is-90 dBm-60 dBm, the handset may not be able to make a call.
Preferably, the signal strength of the neighboring cell and the signal strength of the current cell are subjected to difference processing to obtain a signal strength difference. For example, assuming that the signal strength of the current cell is-35 dBm and the signal strength of the neighboring cell is-25 dBm, the signal strength difference is-25 dBm- (-35dBm) ═ 10 dBm.
And S203, determining whether the signal of the terminal reselects the adjacent cell based on the signal strength difference and the bandwidths of the current cell and the adjacent cell.
It will be appreciated that bandwidth may be used to identify the data transmission capacity of the signalling, i.e. the highest data rate per unit time passing through a point in the network, the greater the bandwidth the greater the transmission capacity of the signalling data, e.g. 4M bandwidth data transmission capacity is greater than 2M bandwidth data transmission capacity.
Illustratively, it is assumed that the signal strength difference is 10dBm, the bandwidth of the current cell is 2M, and the bandwidth of the neighboring cell is 4M, so that since the signal strength of the neighboring cell is greater than the signal strength of the current cell and the bandwidth of the neighboring cell is also greater than the bandwidth of the current cell, it can be determined that the signal of the terminal can be reselected to the neighboring cell.
In the embodiment of the application, the signal strength and the bandwidth of the current cell and the adjacent cell where the terminal is located can be obtained; determining a signal strength difference based on the signal strengths of the current cell and the neighboring cell; and determining whether the signal of the terminal reselects to the adjacent cell or not based on the signal strength difference and the bandwidths of the current cell and the adjacent cell. Therefore, the terminal can be easier to reside or reselect to the cell supporting the large bandwidth, so that the terminal can obtain more network resources, and the data service performance of the user terminal is improved.
In some embodiments, before step S203, the method of the embodiment of the present application may further include: it is determined whether bandwidths of the current cell and the neighboring cell are equal.
Fig. 3 schematically illustrates a flow chart of a terminal signal reselection method provided by an embodiment of the present application. As shown in fig. 3, the terminal signal reselection method may include at least the following steps:
s301, acquiring the signal strength and bandwidth of the current cell and the adjacent cell where the terminal is located.
Specifically, S301 is identical to S201, and is not described herein again.
S302, based on the signal intensity of the current cell and the signal intensity of the adjacent cell, the signal intensity difference is determined.
Specifically, S302 is identical to S202, and is not described herein again.
And S303, under the condition that the bandwidth of the current cell is equal to the bandwidth of the adjacent cell, if the signal intensity difference is greater than a preset first threshold value, reselecting the adjacent cell by the signal of the terminal.
The first threshold is used for representing the reselection threshold of the terminal signal.
Exemplarily, assuming that the first threshold is 10dBm, the bandwidth of the current cell is 5M, the bandwidth of the neighboring cell is 5M, the signal strength of the current cell is-45 dBm, and the signal strength of the neighboring cell is-20 dBm, since the bandwidth of the current cell is equal to the bandwidth of the neighboring cell, a difference 25dBm between the signal strength of the neighboring cell and the signal strength of the current cell is greater than a preset first threshold of 10dBm, and therefore, the signal of the terminal reselects to the neighboring cell.
Therefore, the embodiment of the application realizes that whether the signal of the terminal needs to be reselected to the adjacent cell is determined according to the preset first threshold value under the condition that the bandwidth of the current cell is equal to the bandwidth of the adjacent cell, so as to ensure that the signal of the terminal is always in the cell with the optimal network resource.
Fig. 4 schematically illustrates a flow chart of a terminal signal reselection method provided by an embodiment of the present application. As shown in fig. 4, the terminal signal reselection method may include at least the following steps:
s401, acquiring the signal intensity and bandwidth of the current cell and the adjacent cell where the terminal is located.
Specifically, S401 is identical to S201, and is not described herein again.
S402, based on the signal intensity of the current cell and the signal intensity of the adjacent cell, the signal intensity difference is determined.
Specifically, S402 is identical to S202, and is not described herein again.
And S403, determining a difference value between the signal strength difference and a preset second threshold value under the condition that the bandwidth of the current cell is greater than the bandwidth of the adjacent cell.
And the second threshold value is used for representing the reselection threshold of the terminal signal under the condition that the bandwidth of the current cell is greater than the bandwidth of the adjacent cell.
Possibly, the second threshold may be set to at least twice the first threshold, e.g. the preset first threshold is 10dBm, then the second threshold may be set to at least 20 dBm.
For example, assuming that the preset second threshold is 20dBm, the signal strength of the current cell is-60 dBm, and the signal strength of the neighboring cell is-35 dBm, the signal strength difference between the signal strength of the neighboring cell and the signal strength of the current cell is-35 dBm- (-60dBm) ═ 25dBm, and further, the difference between the signal strength difference and the preset second threshold is 25dBm-20dBm ═ 5 dBm.
And S404, determining whether the signal of the terminal reselects the adjacent cell based on the difference value between the signal strength difference and a preset second threshold value.
Specifically, in the embodiment of the present application, when the bandwidth of the current cell is greater than the bandwidth of the neighboring cell, if a difference between a signal strength difference and a preset second threshold is greater than 0, it is determined that a signal of the terminal may be reselected to the neighboring cell; and if the difference value between the signal strength difference and the preset second threshold value is not greater than 0, determining that the signal of the terminal is resided in the current cell.
S405, determining that the signal of the terminal is reselected to the neighboring cell when the difference between the signal strength difference and the second threshold is greater than 0.
Illustratively, since the difference between the signal strength difference and the preset second threshold value is 5dBm >0 in the above example, the signal of the terminal can be reselected to the neighboring cell.
Exemplarily, in the case that the bandwidth 9M of the current cell is greater than the bandwidth 8.5M of the neighboring cell, assuming that the preset second threshold is 20dBm, the signal strength of the current cell is-60 dBm, and the signal strength of the neighboring cell is-55 dBm, the signal strength difference between the signal strength of the neighboring cell and the signal strength of the current cell is-55 dBm- (-60dBm) ═ 5dBm, and further, the difference between the signal strength difference and the preset second threshold is 5dBm-20dBm ═ -15dBm <0, it may be determined that the signal of the terminal resides in the current cell.
Therefore, according to the embodiment of the application, under the condition that the bandwidth of the current cell is larger than that of the adjacent cell, the signal intensity of the current cell is compared with that of the adjacent cell again according to the preset second threshold value, various factors influencing network resources of the terminal are considered comprehensively, and whether the signal of the terminal needs to be reselected to the adjacent cell is determined finally, so that the signal of the terminal is ensured to be always in the cell with the optimal network resources.
Fig. 5 is a schematic flowchart illustrating a method for reselecting a terminal signal according to an embodiment of the present application. As shown in fig. 5, the terminal signal reselection method may include at least the following steps:
s501, acquiring the signal intensity and bandwidth of the current cell and the adjacent cell where the terminal is located.
Specifically, S501 is identical to S201, and is not described herein again.
S502, determining a signal strength difference based on the signal strengths of the current cell and the neighboring cell.
Specifically, S502 is identical to S202, and is not described herein again.
S503, determining a sum of the signal strength difference and a preset first threshold value when the bandwidth of the current cell is smaller than the bandwidth of the neighboring cell.
Exemplarily, assuming that the first threshold is 12dBm, the bandwidth of the current cell is 5M, the signal strength of the current cell is-45 dBm, the bandwidth of the neighboring cell is 8M, and the signal strength of the neighboring cell is-55 dBm, determining a signal strength difference between the signal strength of the neighboring cell and the signal strength of the current cell, which is-55 dBm- (-45dBm) ═ 10dBm, and since the bandwidth of the current cell is 5M less than 8M of the bandwidth of the neighboring cell, further determining a sum of the signal strength difference and the preset first threshold, which is-10 dBm +12dBm ═ 2 dBm.
And S504, determining that the signal of the terminal is reselected to the adjacent cell under the condition that the sum of the signal intensity difference and a preset first threshold value is greater than 0.
Continuing with the above example, since the sum of the signal strength difference and the preset first threshold value is determined to be 2dBm >0, it is determined that the signal of the terminal can be reselected to the neighboring cell.
In addition, if the sum of the signal strength difference and the preset first threshold is not greater than 0, it may be determined that the signal of the terminal cannot be reselected to the neighboring cell.
Exemplarily, assuming that the first threshold is 12dBm, the bandwidth of the current cell is 5M, the signal strength of the current cell is-45 dBm, the bandwidth of the neighboring cell is 8M, and the signal strength of the neighboring cell is-58 dBm, it may be determined that a signal strength difference between the signal strength of the neighboring cell and the signal strength of the current cell is-58 dBm- (-45dBm) ═ 13 dBm. Since the bandwidth 5M of the current cell is less than 8M of the bandwidth of the neighboring cell, it may be further determined that a sum of the signal strength difference and the preset first threshold value, which is-13 dBm +12dBm, is-1 dBm <0, and it may be determined that the signal of the terminal cannot reselect the neighboring cell and still resides in the current cell.
Therefore, the embodiment of the application realizes that the cell reselection threshold can be dynamically adjusted according to the bandwidths of the current cell and the adjacent cell under the condition that the bandwidth of the current cell is smaller than the bandwidth of the adjacent cell, so that the terminal can more easily reside or reselect to the cell supporting large bandwidth, thereby obtaining more network resources and improving the data service performance of the user terminal.
