Abstract: A Packet Data Protocol (PDP) context handling method for a Mobile Station (MS) with a PDP context for an emergency bearer service is provided, wherein a radio access bearer (RAB) associated with the PDP context is released by a network. The method comprises the steps of: downgrading the maximum uplink bit rate and the maximum downlink bit rate associated with the PDP context from original non-zero positive values to a zero value; sending a request signal associated with a modification of the maximum uplink bit rate and the maximum downlink bit rate; and re-establishing the RAB for the PDP context with the maximum uplink bit rate and the maximum downlink bit rate reconfigured as the original non-zero values after the request signal has been sent.

Abstract: A method of handling CSG list synchronization for a network in a wireless communication system is disclosed. The method comprises associating a version number with a user subscribed CSG identities (IDs) list, wherein the user subscribed CSG IDs list is stored in the network; and sending the version number in a OTA (over-the-air) message or in a NAS (non-access stratum) message when the version number is currently used by the network, wherein the OTA message is intended to update an operator CSG list which is stored in a mobile device.
