发明名称 Method and apparatus for cell barring in a wireless communication system
摘要 Systems and methodologies are described herein that facilitate cell barring based on erroneous messages received within a wireless communication system. As described herein, in the event that a device fails to receive and/or decode respective messages transmitted from a network cell over a common communication channel, the device can implement one or more error handling procedures as described herein to reselect away from the network cell and/or a frequency associated with the network cell (e.g., as if the network cell was explicitly barred). Cell barring can be triggered as described herein based on a count of erroneous messages (e.g., consecutive messages, messages received within a predetermined time window, etc.), elapsed time between erroneous messages, or the like. Further, cell barring can be performed as described herein based on failure to acquire pre-scheduled system information, common system information determined to have invalid abstract syntax, or the like.

主权项 1. A method, comprising: obtaining one or more messages from a designated network cell over a common channel; attempting decoding of the one or more messages; tracking respective errors encountered during the attempted decoding of the one or more messages, wherein the tracking comprises maintaining a count of erroneous messages encountered during the attempted decoding of the one or more messages; and initiating an avoidance procedure associated with barred network cells with respect to the designated network cell according to respective tracked errors associated with the attempted decoding of the one or more messages, wherein the initiating comprises initiating the avoidance procedure associated with barred network cells with respect to the designated network cell upon determining that the count exceeds a predetermined threshold.
