Abstract: An user equipment and a data connection recovery method thereof are provided. The user equipment transmits at least one UDP query packets to a robust server via the base station, and determines that there is no response from the robust server during a default period. Then the user equipment determines that a data connection with a backhaul network is abnormal between the base station and the backhaul network. Accordingly, the user equipment transmits a trigger packet to the backhaul network via the base station under NAS protocol and recovers the data connection with the backhaul network.

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.

Abstract: An electronic device includes a circuit module with a circuit board, and a plug connector with a supporting base, several terminals, and an outer shell. The terminals are disposed at the supporting base, and connected to the circuit board. The outer shell surrounds the supporting base, and has two parallel horizontal plates. Two extending plates are extended from a front surface of one of the horizontal plates. A slot is formed among that horizontal plate and the two extending plates. Via these arrangements, the out shell of the plug connector has the slot, so that the deformation of the outer shell is more easily caused. Thus, even if the assembly tolerance between the plug connector and the socket connector is deviated, the force for plugging or unplugging the plug connector would not be too abnormal. That is because the outer shell can be easily deformed to compensate for the deviation.
