A wireless mobile communication device includes a wireless communication subsystem configured to wirelessly communicate through a local data access point to cause a query to be delivered to a remote access point location database. The location database contains information about the location of local data access points within a widespread area. The query is for location information for data access points located near the wireless device. The wireless device receives nearby access point location information from the database, and the device causes at least a portion of the access point location information to be delivered to a user. This may be done through a user interface, upon request of the user, and while the wireless communication subsystem is not connected to a local data access point.

Duration based accounting for a packet data service, for example offered as a prepaid mobile IP (MIP) service through a public mobile wireless communication network, uses last detected user activity to determine the end of each session for accounting purposes. The accounting policy or algorithm defines user activity so as to include receipt of signaling related to the MIP session, such as signaling related to a termination by the user or the user's mobile station, in addition to packet data routed for the mobile station. If a session ends due to a network termination, e.g. binding expires or the network disconnects upon prepaid quota exhaustion, then the last user activity used for accounting purposes is the last data packet communication to/from the mobile station or the last received MIP session-related signaling message. For example, if MIP signaling terminates the session, then the session duration runs until receipt of that signaling.

A method and system for facilitating prepaid mobile messaging. Mobile messages are forwarded to their intended one or more destinations before the debit account of the one or more prepaid mobile messaging subscribers associated with the mobile message are debited.
