Abstract
In some implementations, a method includes receiving a connection request from a user application. A service request is sent to a radio resource control (RRC) module. An indication of failure of or a rejection to the service request due to access class barring is received from the RRC module. A retry of the user application connection request is prevented until expiration of an access-class-barring timer of the RRC module that resulted in the access class barring.
Claims15
A method, comprising:
- sending a service request to a radio resource control (RRC) module, wherein the service request is generated in response to a connection request from a user application or a non-access stratum (NAS) module;
- receiving, from the RRC module, an indication of failure of or a rejection to the service request due to access class barring;
- in response to receiving the indication of failure or the rejection, preventing a retry of the service request until expiration of an access-class-barring timer of the RRC module that resulted in the access class barring, wherein preventing a retry of the service request comprises aligning a retry timer for the service request to the access-class-barring timer;
- and
- informing the user application when the access-class-barring timer will expire.

A mobile device, comprising:
- one or more processors configured to:
- send a service request to a radio resource control (RRC) module;
- receive, from the RRC module, an indication of failure of or a rejection to the service request due to access class barring;
- in response to receiving the indication of failure or the rejection, prevent a retry of the service request until expiration of an access-class-barring timer of the RRC module that resulted in the access class barring, wherein preventing a retry of the service request comprises aligning a retry timer for the service request to the access-class-barring timer;
- and
- inform the user application when the access-class-barring timer will expire.
