Enhanced access class barring mechanism in LTE
View Patent ↗Systems, methods, and computer-readable media for providing enhanced access class barring in LTE are provided. In embodiments, the method includes receiving, on a mobile device, a SIB2 message. A barring factor associated with the SIB2 message is identified. In embodiments, the barring factor is dynamic based on traffic parameters associated with a network. An upper limit for a random number is set on the mobile device and the random number is generated. The random number is generated and compared to the barring factor. If the random number is less than the barring factor, access to the network is provided to the mobile device. In embodiments, an additional random number is generated for special users or devices if the random number is greater than or equal to the barring factor.
1. Non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, facilitate a method of providing priority access to special users or devices, the method comprising:
designating a mobile device as a special mobile device, the special mobile device being configured to set an upper limit for a random number generated by the special mobile device, wherein the special mobile device is associated with one or more users having priority access to a network;
receiving, on the special mobile device, a SIB2 message;
determining a barring factor associated with the SIB2 message;
setting, on the special mobile device, the upper limit for the random number, the upper limit being less than the barring factor;
generating the random number, wherein the random number is less than the barring factor;
comparing the random number to the barring factor; and
providing access to the special mobile device.
2. The media of claim 1 , wherein the special mobile device is associated with a special access class.
3. The media of claim 1 , wherein the special mobile device is a machine-to-machine (M2M) device.
4. The media of claim 1 , wherein the barring factor is dynamic and based on a load associated with the network.
5. The media of claim 1 , wherein the network is a telecommunications network.
6. A computer system for providing access control for special users and devices, the computer system comprising a processor coupled to a non-transitory computer-storage medium, the computer-storage medium having stored thereon a plurality of computer software components executable by the processor, the computer software components comprising:
a receiving component for receiving a SIB2 message;
a determining component for determining a barring factor associated with the SIB2 message;
an upper limit component for setting, on a special mobile device, an upper limit for the random number, the upper limit being less than the barring factor, wherein the special mobile device is associated with one or more users having priority access to a network;
a random number component for generating a random number below the barring factor;
a comparison component for comparing the random number to the barring factor; and
an access component for providing access to the mobile device.
7. The computer system of claim 6 , wherein the network is a telecommunications network.
8. The computer system of claim 7 , wherein the barring factor is static.
9. The computer system of claim 6 , wherein the special mobile device is associated with a special access class.
10. The computer system of claim 6 , wherein the special mobile device is a machine-to-machine (M2M) device.
11. The computer system of claim 6 , wherein the barring factor is dynamic and based on a load associated with a network.
