<p>A method for synchronously maintaining packet data protocol (PDP) context status between a wireless communication network and a mobile station and an associated mobile station are disclosed to prevent from the asynchronous PDP context status caused by the prior arts. When both the mobile station and the network activate a PDP context for a packet-switched service, if the mobile station is to establish a circuit-switched connection with the network and dual transfer mode (DTM) is not supported, the mobile station will request the network to suspend the packet-switched service. After the circuit-switched connection is established, the mobile station locally deactivates the PDP context. After the circuit-switched connection is disconnected, if the network informs the mobile station that the packet-switched service is resumed, the mobile station will inform the network that the PDP context has been deactivated.</p> |
