8. the prohibition period of the timer T390 is generated according to the formula (1), and T390 is started.
T390＝(0.7+0.6*rand)*uac-BarringTime (1)
Wherein, T390 in the formula (1) is the prohibited duration of the timer T390, rand is a random number generated between 0 and 1 implemented in 7, and uac-BarringTime is the value of the access control parameter uac-BarringTime.
Through the implementation process, after the fact that the access is forbidden at this time is judged, the operation duration of the T390 is also set, the T390 is started, the terminal is in the access forbidden state in the operation process of the T390, and the terminal is forbidden to access the network at this time, so that the problem of network congestion can be greatly relieved.
Currently, in the process of T390 operation, T390 may be stopped in the following scenarios to link access to the forbidden state, such as: a terminal performs a cell reselection scene; the terminal enters a scene of a connection state; the terminal receives the wireless link reconfiguration and the wireless link reconfiguration message carries the scene of the reconfigurationWithSync; a scene that the Pcell changes in a connected state; a terminal receives a scene of a command for switching to Long Term Evolution (LTE); and the terminal receives the scene of the wireless link release message.
However, when the terminal receives a new system message and the new system message is used to indicate that the access class and the access identifier corresponding to the access barring are not barred, the barring access status and T390 are not processed in the current protocol; or when the terminal receives a new system message, and the access class and the access identifier corresponding to the access barring are still barred in the new system message, but the access control parameter changes, the current protocol does not process the barred access state and the T390. Therefore, for the current protocol, in the operation process of T390, the network side cannot control the terminal to change the access prohibition state and the T390 state, thereby causing the problem of poor flexibility of network access.
In order to solve the above problem, the present application provides an access control method, and specific embodiments are described below.
It should be understood that the specific embodiments described herein are merely illustrative of the present application. And are not intended to limit the present application.
An embodiment of the present application provides an access control method, as shown in fig. 4, the method may include:
s101, when the timer for prohibiting access runs and is in a state of prohibiting access to a network and the first system message is received, controlling the timer for prohibiting access according to the first system message so as to control the access operation to the network.
The access control method provided by the embodiment of the application is suitable for a scene that a terminal accesses a network in an access forbidden period.
In the embodiment of the present application, the terminal implementing access control may be any device having communication and storage functions, for example, including but not limited to: chips, tablet computers, mobile phones, personal Computers (PCs), notebook computers, cameras, wearable devices, and the like.
It should be noted that, when the terminal is triggered to enter the access prohibition state, the timer for prohibiting access is started, and the access prohibition is used for prohibiting the terminal from accessing the network during the running process of the timer; before the terminal enters the access prohibition state, an access prohibition period is set for the timer for prohibiting access, and the access prohibition period is the timing duration of the timer for prohibiting access.
The prohibit access timer is a timer such as a T390 timer for controlling the terminal to prohibit access to the network, and may be specifically selected according to the actual situation, and the embodiment of the present application is not specifically limited.
In the embodiment of the application, in the process of the operation of the timer for prohibiting access, a first system message sent by a network side is received, and at this time, the terminal can control the timer for prohibiting access according to parameters carried in the first system message so as to control the terminal to perform the operation of network access.
Specifically, whether a first system message carries a first access control parameter is judged, and under the condition that the first system message comprises the first access control parameter, a timer for forbidding access is controlled according to the first access control parameter; performing a network access operation under the condition that the first system message does not contain the first access control parameter; at this time, the terminal may send a data service access request to the network side.
In this embodiment of the present application, when the first system message includes the first access control parameter, a specific process of controlling the timer for barring access according to the first access control parameter is as follows: firstly searching for a received access grade when a timer for forbidding access is generated, judging whether a first access grade which is the same as the access grade received when the timer for forbidding access is generated can be searched from a first access control parameter, and controlling the timer for forbidding access according to the first access grade under the condition that the first access control parameter comprises the first access grade; and performing network access operation when the first access control parameter does not include the first access level.
In the embodiment of the present application, when the first access control parameter includes the first access class, a specific process of controlling the timer for barring access according to the first access class is as follows: acquiring an identification bit of an access mark corresponding to a first access grade from a first access control parameter; if the identification bit of the access mark is characterized as access permission, performing network access operation; and if the zone bit of the access identifier is characterized as access prohibition, acquiring a first prohibition time parameter from the first access control parameter, and controlling the timer for prohibiting access according to the first prohibition time parameter.
Illustratively, the first barring time parameter is a uac-BarringTime parameter, and when the flag bit of the access identifier is 0, the terminal notifies the high level of the terminal of the access barring status release and performs a network access operation; and when the identification bit of the access mark is 1, acquiring a parameter value of the uac-BarringTime from the first access control parameter, and controlling a timer for forbidding access according to the parameter value of the uac-BarringTime.
Specifically, the specific process of controlling the timer for barring access according to the first barring time parameter includes: and controlling the timer for forbidding access according to the first forbidding time parameter, the timing duration of the timer for forbidding access and the running time period of the timer for forbidding access.
In an alternative embodiment, the specific process of controlling the timer for barring access according to the first barring time parameter, the timing duration of the timer for barring access and the running period of the timer for barring access may be: determining a current prohibiting period maximum and a current prohibiting period minimum based on the first prohibiting time parameter; updating the timing duration of the timer for forbidding access under the condition that the timing duration of the timer for forbidding access is greater than the maximum value of the current forbidding period or the timing duration of the timer for forbidding access is less than the minimum value of the current forbidding period; and under the condition that the timing duration of the timer for prohibiting access is between the maximum value of the current prohibiting period and the minimum value of the current prohibiting period, the terminal continues to run the timer until the timer stops running and then performs network access operation.
It should be noted that, the process of determining the maximum value of the current prohibition period based on the first prohibition time parameter can be implemented by formula (2):
T max ＝uac-BarringTime×(0.7+0.6) (2)
wherein, T max Is the maximum value of the current forbidden time period; the uac-BarringTime is the first barring time parameter.
It should be noted that, the process of determining the minimum value of the current prohibition period based on the first prohibition time parameter can be implemented by equation (3):
T min ＝uac-BarringTime×0.7 (3)
wherein, T min A current forbidden time period minimum value; the uac-BarringTime is the first barring time parameter.
For an alternative embodiment, the process of updating the timing duration of the timer for prohibiting access may specifically be: under the condition that the timing duration of the timer for forbidding access is greater than the maximum value of the current forbidding time period, determining the updated forbidding access time period according to the running time period of the timer for forbidding access and the maximum value of the current forbidding time period; and under the condition that the timing duration of the timer for forbidding access is smaller than the minimum value of the current forbidding time period, determining the updated forbidding access time period according to the running time period of the timer for forbidding access and the minimum value of the current forbidding time period.
Illustratively, when T is determined max Then, the updated prohibited access time period is T max A difference value with an already running period of the timer for prohibiting access; when T is determined min Then, the updated prohibited access time period is T min And the running time period of the timer for forbidding access.
In another alternative embodiment, the specific process of controlling the timer for barring access according to the first barring time parameter, the timing duration of the timer for barring access, and the running period of the timer for barring access may be: firstly, generating a random number; then calculating a new access prohibition period based on the first prohibition time parameter and the random number; acquiring the running time of the timer in the access prohibition period; the terminal compares the new access prohibition time period with the running time period of the timer for prohibiting access, and updates the timing duration of the timer for prohibiting access under the condition that the new access prohibition time period is greater than the running time period of the timer for prohibiting access; and performing network access operation when the new access prohibition period is less than or equal to the running period of the timer for prohibiting access.
Illustratively, a random number rand is generated between 0-1, after which a new barred access period is calculated using equation (4).
T390_temp＝(0.7+0.6×rand)×uac-BarringTime (4)
Wherein, T390_ temp is a new barring time period, and uac-BarringTime is a first barring time parameter.
It should be noted that, the process of comparing the new prohibited access period with the running period of the timer for prohibited access by the terminal may be directly comparing the new prohibited access period with the running period of the timer for prohibited access; or determining a difference value between the new access prohibition period and the running period of the timer for prohibiting access, and comparing the difference value with 0, for example, when the difference value between the new access prohibition period and the running period of the timer for prohibiting access is greater than 0, updating the timing duration of the timer for prohibiting access; when the difference value between the new access prohibition period and the running period of the timer for prohibiting access is not more than 0, performing network access operation; the specific comparison method may be selected according to actual situations, and is not limited specifically herein.
For the another alternative embodiment, the process of updating the timing duration of the timer for barring access may specifically be: firstly, determining the difference value of the new access prohibition period and the running period of the timer for prohibiting access; and determining the difference value as the updated access prohibition period.
It should be noted that, for the method of comparing the difference between the new prohibited access period and the running period of the timer for prohibited access with 0, when the difference between the new prohibited access period and the running period of the timer for prohibited access is greater than 0, the difference between the new prohibited access period and the running period of the timer for prohibited access is directly determined as the updated prohibited access period.
It is to be understood that, by the above-mentioned one alternative embodiment and the above-mentioned another alternative embodiment, the terminal may update the prohibited access period of the timer according to the first prohibited time parameter, set the timer according to the updated prohibited access period, and restart the timer. Therefore, when the congestion state of the network changes, such as the congestion state is relieved or the congestion state is aggravated, the network side can modify the access control parameters based on the change of the congestion state, further update the current access prohibition period, and shorten or prolong the access prohibition duration of the terminal according to the current congestion state.
