Abstract: The method and apparatus for accelerating connection establishment in a mobile communications system are provided. The method includes transmitting, by a user equipment, an Activate PDP Context Request to a network; determining whether the user equipment can be confirmed that the network received the Activate PDP Context Request by an lower layer; shortening a default timer value and retransmitting the Activate PDP Context Request to the network after the shortened default value if the lower layer does not confirm that the network received the Activate PDP Context Request; and preserving the default timer value if the lower layer confirms that the network received the Activate PDP Context Request.

Abstract translation: 提供了一种用于加速移动通信系统中的连接建立的方法和装置。 该方法包括：通过用户设备向网络发送激活PDP上下文请求; 确定用户设备是否可以确认网络是否通过下层接收到激活PDP上下文请求; 缩短默认定时器值，如果下层未确认网络接收到激活PDP上下文请求，则在缩短的默认值之后，向网络重传激活PDP上下文请求; 并且如果下层确认网络接收到激活PDP上下文请求，则保留默认定时器值。

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a first cell of a first Public Land Mobile Network (PLMN) and a second cell of a second PLMN. The controller performs a Location Update (LU) procedure with the second cell via the wireless transceiver in response to an inter-PLMN handover of the UE from the first cell of the first PLMN to the second cell of the second PLMN, and obtains one or more Session Management (SM), Evolved SM (ESM), or 5GSM parameters of the second PLMN from a Protocol Data Unit (PDU) session modification command, a bearer modification command, or a Packet Data Protocol (PDP) context modification command which is received from the second cell via the wireless transceiver in response to completing the LU procedure caused by the inter-PLMN handover.
