Enhance AT command for backoff timer control
First Claim
1. A method, comprising:
- transmitting a first Attention (AT) command by a terminal equipment (TE) in a mobile communication network, wherein the first AT command is for querying backoff timer status information associated with an access point name (APN);
receiving a response from a mobile termination (MT), wherein the response includes the backoff timer status information; and
scheduling a second AT command associated with the corresponding APN based on the backoff timer status information.

Abstract
AT commands are used for controlling Mobile Termination (MT) functions and GSM/UMTS network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). 3GPP introduces multiple backoff timers and barring to solve network congestion problem. However, a TE does not know the timer value and the barring status. In accordance with one novel aspect, a new AT command interface that can respond timer value and barring status to the TE is proposed. It reduces wasteful retries and saves power consumption of the TE. Through the new AT command interface, the TE can query backoff timer status. Via unsolicited result code (URC), the MT can detect backoff timer status change and report updated backoff timer status to the TE.

17. A method, comprising:
-
receiving a first Attention (AT) command by a mobile termination (MT) from a co-located terminal equipment (TE) of a user equipment (UE) in a mobile communication network, wherein the first AT command is for querying backoff timer status information associated with an access point name (APN); determining the backoff status information by the MT, wherein the MT transmits a response including the backoff timer status information to the TE; and scheduling a second AT command associated with the corresponding APN based on the backoff timer status information such that the second AT command is not barred by the network. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
