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 service network. The controller receives a response message of a Non-Access Stratum (NAS) procedure for establishing or modifying a Protocol Data Unit (PDU) session from the service network via the wireless transceiver, and determines that Reflective Quality of Service (RQoS) is not applied for the PDU session in response to the response message including an RQoS timer (RQ timer) value set to zero or deactivated.

Abstract: A method can include receiving a non-access stratum (NAS) message for establishing or modifying a protocol data unit (PDU) session at a user equipment (UE) from a core network, determining whether there is a quality of service (QoS) flow description resulting from the establishment or modification of the PDU session that is associated with a guaranteed bit rate (GBR) QoS flow of the PDU session, and invalid, and when it is determined that there is the invalid QoS flow description associated with the GBR QoS flow of the PDU session, performing an error handling operation.

Abstract: A method for handling network recommended Mobile Country Code (MCC) information is provided. A User Equipment (UE) receives an indication of country of UE location from a satellite-access 3rd Generation Partnership Project (3GPP) network. The UE stores the indication and starts a timer in response to receiving the indication. The UE keeps the stored indication valid until the timer expires.

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。
