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. Show less

Exemplary network infrastructures and methods employing a Security Gateway utilize client authentication for use of a secure connection between an application client and an application server of a protected network. Once a secure connection has been set up, a Security Gateway can start a timer for establishing a period within which a password and username are to be received from the application client before traffic is allowed to exit the Security Gateway. If a username and password are provided while the timer is running, the Security Gateway can contact a single sign on (SSO) server to check whether the username and password are correct. If the username and password are valid, the Security Gateway can start relaying traffic externally to the application server. If an invalid username and password are provided or the timer times out before receipt of a username and password, the secure connection can be terminated. Show less

Method and system for routing traffic across multiple network interfaces with use of VPN traffic selector as part of decision making, for example, in the context of a mobile communication network. A packet data unit (PDU) is generated in association with an application that can be selectively activated on a mobile device and carries a destination Internet protocol (IP) address representing a server that supports the application. A broker associated with the mobile device retrieves information relating to traffic selectors and determines whether the PDU is associated with an operator application or a non-operator application based on the destination IP address and the information relating to traffic selectors. The broker routes the PDU to one of the multiple network interfaces based on whether the PDU is from an operator application traffic and local policies. When the PDU is associated with an operator application and the mobile device is not connected to its operator network, the PDU is routed via a virtual private network (VPN) selector. Show less

restrictions for a subscriber station for some time period when
it is detected that an emergency call was made by that subscriber
station, so as to disable the restriction that would
otherwise block completion of an incoming call to that station.
This allows a call placed by emergency personnel in
response to the emergency call from the subscriber station
(i.e. when the emergency personnel calls back the user that is
involved in the emergency) to bypass any restrictions setup by
the subscriber or by the network that would otherwise block
the callback and allows the emergency callback to potentially
reach the caller. This approach results in a systematic solution
to blocking of emergency callbacks that applies to various
kinds of restriction services yet is relatively simple to administer. Show less

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. Show less

In a network offering prepaid services, for example, an applicable accounting policy is identified each time a user requests a new session. Different session classifications are possible under the identified policy. For example, if the prepaid subscriber also subscribes to a push-to-talk (PTT) service, the policy enables classification of each session as either PTT or non-PTT. A different policy would apply if the prepaid subscriber did not subscribe to the PTT service. A network element serving the mobile station during the session monitors packets, until it can detect a packet enabling appropriate classification under the applicable policy. The prepaid platform bases its accounting on the session classification. For a prepaid subscriber with PTT service, for example, a non-PTT session receives normal prepaid treatment based on session duration, whereas packet transport for a PTT session may be free.
