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.

Abstract: Methods and apparatus are provided for inter-RAT bearer change for the 3GPP network. In one novel aspect, a bearer termination procedure is performed upon detecting one or more triggering events for the inter-RAT bearer modification. In one embodiment, the UE established the 4G EPS bearer. The UE successfully performs a bearer change from 4G to 3G. Subsequently, the UE detects missing mandatory parameters during inter-RAT bearer change from 3G to 2G in an idle state. The UE performs bearer termination by releasing the PDP context. In one embodiment, the PDP context is locally released. In other embodiments, the UE explicitly releases bearer using the PDP context deactivation procedure. The locally released procedure can be triggered by the UE, or by the network, or by both the UE and the network. The explicitly PDP context release procedure can be triggered by the UE, or by the network, or by both the UE and the network.

Abstract: Methods and apparatus are provided for enhanced bearer continuity for the 3GPP network. In one novel aspect, the UE detects missing parameters for the inter-RAT bearer change in an idle state. The UE performs bearer preservation procedures to maintain the bearer continuity. In one embodiment, predefined/preconfigured parameter settings are used. In one embodiment, a mapping rule is used to map the missing parameter to a predefined value based on one or more known parameters. In another embodiment, the missing parameters are obtained from the network. In another embodiment, signaling procedures used to obtain the missing parameters. The signaling procedures include a service request, a UE-initiated bearer modification procedure. In one embodiment, the cell reselection is suspended such that the signaling procedure is performed to obtain the missing parameters before the cell reselection. In another embodiment, a RAU procedure is used upon detecting the missing of parameters.
