Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Referring to fig. 1, a flowchart illustrating a first step of an access control method of a mobile terminal according to the present application is shown, which may specifically include the following steps:
Wherein, the resource usage status may include: saturated and unsaturated states. The saturation state means that the physical resources and the RRC resources of the cell are not idle or have a small amount of idle, but cannot support the service requirement of the newly accessed mobile terminal; the unsaturated state means that there is enough idle physical resources and RRC resources of the cell to support the service requirement of the newly accessed mobile terminal.
The broadcast information is information sent by the cell to the mobile terminal, and is used for sending the relevant information of the cell to the mobile terminal so as to assist the mobile terminal in making a decision. The broadcast information is generated periodically, for example, once in 20 milliseconds.
The resource usage rate may include, but is not limited to: physical resource usage and radio resource usage.
The physical resource usage may be obtained according to the following sub-steps a1 to a 2:
sub-step a1, determining the total number of physical channels of the cell of the base station and the number of physical channels in use among the physical channels.
Sub-step a2, determining the physical resource usage rate of the cell of the base station according to the ratio of the number of physical channels in use state to the total number of the physical channels.
It is understood that the sum of the number of physical channels in the used state and the number of physical channels in the idle state is the total number of physical channels.
Specifically, the ratio of the number of physical channels in use to the total number of physical channels may be used as the physical resource usage rate. For example, the total number of physical channels is PC1, the number of physical channels in the use state is PC2, and the number of physical channels in the idle state is PC1 to PC2, so that PC2/PC1 can be used as a physical resource.
In addition, the ratio may be subjected to linear transformation or nonlinear transformation to obtain the physical resource usage rate, but a forward relationship between the ratio and the physical resource usage rate needs to be ensured: if the ratio is larger, the physical resource utilization rate is larger; if the ratio is smaller, the physical resource utilization rate is smaller. For example, the total number of physical channels is PC1, the number of physical channels in the use state is PC2, and the number of physical channels in the idle state is PC1-PC2, so that the PC2/PC1 can be subjected to linear transformation a × PC2/PC1+ b to obtain the physical resource usage rate, where a and b are coefficients of the linear transformation, respectively.
The radio resource usage may be obtained according to sub-steps B1 to B2 as follows:
sub-step B1, determining the total number of radio channels of the cell of the base station and the number of radio channels in use among the radio channels.
And a sub-step B2 of determining the radio resource utilization rate of the cell of the base station according to the ratio of the number of the radio channels in the use state to the total number of the radio channels.
It is understood that the sum of the number of radio channels in the used state and the number of radio channels in the idle state is the total number of radio channels.
Specifically, the ratio of the number of radio channels in use to the total number of radio channels may be directly used as the radio resource usage rate. For example, the total number of radio channels is RC1, the number of radio channels in the use state is RC2, and the number of radio channels in the idle state is RC1 to RC2, so that RC2/RC1 can be used as a radio resource.
In addition, the ratio may also be subjected to linear transformation or nonlinear transformation to obtain the radio resource usage rate, but a forward relationship between the ratio and the radio resource usage rate needs to be ensured: if the ratio is larger, the wireless resource utilization rate is larger; if the ratio is smaller, the radio resource usage rate is smaller. For example, the total number of radio channels is RC1, the number of radio channels in the use state is RC2, and the number of radio channels in the idle state is RC1 to RC2, so that linear transformation a × RC2/RC1+ b can be performed on RC2/RC1 to obtain the radio resource usage rate, where a and b are coefficients of the linear transformation, respectively.
It is to be understood that in practical applications, at least one of the physical resource usage rate and the wireless resource usage rate may be used as the resource usage rate.
The usage threshold may be set according to an actual application scenario, and is not limited in the present application. For example, the usage threshold may be set to 80%. It can be understood that, when the usage rate threshold is too large, for example, the usage rate threshold is set to 95%, which results in determining the actual saturated state as the unsaturated state, for example, determining the resource usage rate as 90% as the unsaturated state, but after the mobile terminal is accessed to the cell, the cell cannot actually support the service requirement of the newly accessed cell, and finally, the service requirement cannot be supported after the mobile terminal is accessed to the cell, so that the user experience is poor; when the usage threshold is too small, for example, the usage threshold is set to 30%, which results in determining that the actual non-saturated state is the saturated state, for example, determining that the resource usage rate is 40% as the saturated state, but actually the cell may also support the service requirement of the newly accessed cell, and finally the cell resource is wasted.
The saturation state can be identified by any type of character, for example, by the value "1" or by the string "plump". The present application does not impose limitations on the specific representation of the saturation state. Thus, the value "1" representing the saturation state may be assigned to the variable "cellResourceForUse" representing the resource usage state, and the character string "plomp" representing the saturation state may be assigned to the variable "cellResourceForUse" representing the resource usage state.
Specifically, when the resource utilization rate is the physical resource utilization rate, the resource utilization rate of the cell is greater than or equal to a preset utilization rate threshold, that is: the physical resource utilization rate of the cell is greater than or equal to a preset physical resource utilization rate threshold value; the resource utilization rate of the cell is smaller than a preset utilization rate threshold, namely: the physical resource utilization rate of the cell is less than a preset physical resource utilization rate threshold value.
When the resource utilization rate is the wireless resource utilization rate, the resource utilization rate of the cell is greater than or equal to a preset utilization rate threshold, that is: the wireless resource utilization rate of the cell is greater than or equal to a preset wireless resource utilization rate threshold value; the resource utilization rate of the cell is smaller than a preset utilization rate threshold, namely: the wireless resource utilization rate of the cell is less than a preset wireless resource utilization rate threshold value.
Of course, the relationship between the resource usage rate of the cell and the usage rate threshold may also be determined by combining the physical resource usage rate and the radio resource usage rate, that is: if the physical resource utilization rate of the cell is greater than or equal to a preset physical resource utilization rate threshold value, and the wireless resource utilization rate of the cell is greater than or equal to a preset wireless resource utilization rate threshold value, determining that the resource utilization rate of the cell is greater than or equal to the preset utilization rate threshold value; and if the physical resource utilization rate of the cell is smaller than a preset physical resource utilization rate threshold value, or the wireless resource utilization rate of the cell is smaller than a preset wireless resource utilization rate threshold value, determining that the resource utilization rate of the cell is smaller than the preset utilization rate threshold value.
It can be understood that, since the broadcast information is generated periodically and the period is short, the resource usage state can be updated to the saturation state in real time, which is helpful for the mobile terminal to accurately determine the accessed cell according to the latest resource usage state.
And 104, sending the broadcast information to a mobile terminal in the coverage of the cell so that the mobile terminal can determine whether to access the cell according to the resource use state.
In practical applications, there are usually a plurality of mobile terminals within the coverage area of the cell, so that these mobile terminals can all receive the broadcast information.
Of course, each mobile terminal may receive broadcast information of multiple cells, so that which cell is accessed may be determined according to the resource usage status and the access policy in the broadcast information. Wherein, the access strategy can be as follows: randomly selecting a cell from the cells with the resource use state being the unsaturated state to access the cell; or, if the resource usage states of the cells are all saturated states, randomly selecting one cell from all the cells to access the cell. In addition, the accessed cell can be further selected by combining the resource utilization rate. For example, a cell with the lowest resource utilization rate is selected from cells with resource utilization states in unsaturated states to access the cell; or, if the resource usage states of the cells are all in a saturated state, selecting the cell with the lowest resource usage rate from all the cells to access the cell.
Optionally, in another embodiment of the present application, the broadcast information includes a cell access information element, and the cell access information element includes a field indicating a resource usage state.
The broadcast information includes a plurality of information elements, and the cell access information element is used as an information element in the broadcast information. The broadcast information may be, for example, systemlnformationblock 1, i.e.: system information block 1.
The information in the cell access information element, which may be, for example, cellaccesratedinfo, is used to assist the mobile terminal in determining whether to access the cell.
The resource usage status may be a field of the cell access information element, and the resource usage status may be, for example, cellResourceForUse, so that the systemlnformaticblock 1 includes cellaccesratedlnfo information element and the rest of the information elements, the cellaccesratedlnfo information element includes several fields, and cellResourceForUse is one of the fields.
According to the method and the device, a new field can be added in the cell access information element in the broadcast information to serve as a resource use state, and the method and the device are favorable for improving the uniformity of the broadcast information.
Optionally, in another embodiment of the present application, the method further includes step a:
step A, if the resource utilization rate of the cell is smaller than the utilization rate threshold, setting the resource utilization state to be a non-saturated state.
Specifically, the setting of the resource usage state to the unsaturated state may be, for example, assigning a character string "not p" representing the unsaturated state to a variable "cellResourceForUse" representing the resource usage state, or assigning a value "0" representing the unsaturated state to a variable "cellResourceForUse" representing the resource usage state.
It can be understood that since the broadcast information is generated periodically and the period is short, the resource usage state can be updated to the unsaturated state in real time, which is helpful for the mobile terminal to accurately determine the accessed cell according to the latest resource usage state.
The resource usage state can be set to the unsaturated state when the resource usage rate is smaller than the usage rate threshold, and step 104 is performed. Thereby controlling the access of the mobile terminal to the cell.
Optionally, in another embodiment of the present application, the step 104 includes the sub-step B1:
sub-step B1, sending the broadcast information to the mobile terminal in the coverage of the cell, so that the mobile terminal determines to access the cell when the resource usage state of the cell is a non-saturated state.
Specifically, the mobile terminal has searched three cells: cell1, Cell2, and Cell3 may allow the mobile terminal to access Cell1 if the resource usage status of Cell1 is not saturated.
According to the method and the device, when the resource use state of the cell is the unsaturated state, the mobile terminal can be directly accessed to the cell in the unsaturated state without judging the state of other cells, so that the access efficiency of the mobile terminal is improved.
Optionally, in another embodiment of the present application, the step 104 includes the sub-step B2:
substep B2, sending the broadcast information to a mobile terminal in the coverage of the cell, so that the mobile terminal determines not to access the cell when the resource usage state of the cell is a saturated state and a non-saturated cell exists, where the non-saturated cell includes: and the cell of which the resource use state is the unsaturated state in the cell list searched by the mobile terminal.
Specifically, for three cells searched by the mobile terminal: cell1, Cell2, and Cell3, if the resource usage states of Cell1, Cell2, and Cell3 are non-saturated state, and non-saturated state, respectively, the mobile terminal is not allowed to access Cell 2.
According to the method and the device, when the resource use state of the cell is in the saturation state, the mobile terminal is not accessed to the cell in the saturation state but is accessed to the cell in the non-saturation state, and therefore the communication quality of the mobile terminal after being accessed to the cell is improved.
Optionally, in another embodiment of the present application, the step 104 includes the sub-step B3:
and a substep B3, sending the broadcast information to the mobile terminal in the coverage of the cell, so that the mobile terminal determines whether to access the cell according to a random policy when the resource usage state of the cell is a saturated state and a non-saturated cell does not exist.
Specifically, for three cells searched by the mobile terminal: the Cell1, the Cell2, and the Cell3 may allow the mobile terminal to access any one of the cells of the Cell1, the Cell2, and the Cell3 if the resource usage states of the received cells 1, Cell2, and Cell3 are all non-saturated states.
According to the method and the device, the mobile terminal can be randomly accessed to one of the cells when the searched cells are all in a saturated state, so that the situation that the mobile terminal cannot be accessed to any cell is avoided, and the access rate is improved.
Optionally, in another embodiment of the present application, after the broadcast information is generated, the method further includes step C:
and step C, setting the resource use state as a default unsaturated state.
The resource using state is set to be an unsaturated state under the default condition. For example, when broadcast information is generated for the first time after cell activation, a string "not plunger" representing a non-saturated state may be assigned to a variable "cellResourceForUse" representing a resource usage state, or a value "0" representing a non-saturated state may be assigned to a variable "cellResourceForUse" representing a resource usage state.
The resource usage status may be set to the non-saturated status by default, and step 104 is performed, so that the mobile terminal is allowed to access the cell by default.
The application provides an access control method of a mobile terminal, which comprises the following steps: generating broadcast information, wherein the broadcast information comprises a resource use state; determining a resource utilization rate of a cell of the base station; if the resource utilization rate of the cell is greater than or equal to a preset utilization rate threshold value, setting the resource utilization state to be a saturated state; and sending the broadcast information to a mobile terminal within the coverage range of the cell so that the mobile terminal determines whether to access the cell according to the resource use state. According to the method and the device, the resource using state of the cell can be sent to the mobile terminal through the broadcast information, so that the mobile terminal can determine whether to access the cell, the time consumed by access failure is reduced, and the access efficiency of the mobile terminal is improved.
