Abstract: The present invention provides the benefits of negotiated network resources to session-unaware applications. When a session-unaware application runs on a mobile device, the device, knowing that the application is session-unaware, negotiates appropriate network-policy parameters for the application. The application remains unaware, but it receives the benefits of the network-policy parameter negotiation. The network-policy parameter negotiation is carried on between the mobile device and a “network policy mediator” in the network. Together, they reserve the appropriate network resources and secure the appropriate guarantees. In some embodiments, a software “shim” runs in the network-protocol stack on the mobile device. By intercepting network-access attempts sent by the session-unaware application, the shim knows to begin the network-policy parameter negotiation. In some embodiments, the mobile device downloads information about session-unaware applications from the network.

Abstract: A system and method are described whereby an IP telemetry gateway is hosted by an MVNO in order to relay the telemetry information between remote devices located in an IP network and telemetry servers operated by legacy telemetry customers. In an embodiment, the IP network is a CDMA2000 1X wireless network. Once the IP network identifies a device as part of the telemetry network, it assigns such device a static private IP address. A VPN connection is used to extend the private network of remote devices to the IP telemetry gateway. The IP telemetry gateway maps each remote device's legacy address to its corresponding IP address in order to communicate with the legacy servers and the wireless network via circuit switched and packet data connections respectively. Preferably, the remote devices maintain an always on data connection to allow the telemetry servers to address the remote devices at any time.

Abstract: Embodiments of the invention are used to provide a system and method for tearing down and reclaiming an IP address from a multi-IP stack device based on configurable timer parameters that provide a network operator with independent control over each protocol-specific IP network layer session. Dedicated idle and session timers for each IP network layer session are implemented at the network layer of various network nodes in order to independently tear down IPv4 and IPv6 network sessions while maintaining the underlying link layer connection. In embodiments, the IP protocol-specific idle and session timers are processed by the Packet Data Serving Node (PDSN) or the Home Agent (HA).

Abstract: A femto cell is provided that automatically routes new communication sessions among the connected mobile and landline handsets based upon local detection of mobile registration with the femto cell, which helps to reduce the backhaul bandwidth requirements and offload backend network processing load. When the mobile handset successfully registers with the femto cell, a User Detection Module at the femto cell routes new calls destined for the mobile telephone number to one or more traditional landline handsets. The femto cell also provides a ring tone to the connected landline handsets for making the outgoing calls. Since the mobile handset remains available for conducting additional communication sessions, the user is able to talk on the landline handset while conducting a simultaneous data session using the mobile phone.

Abstract: A system and method are described for providing and using an inter-working location gateway (IWLG) that allows a trusted/non-trusted user plane mobile node to successfully utilize user location services while data roaming. In an embodiment, once the mobile node establishes a data connection while roaming, the mobile node uses IP connectivity to exchange messages, e.g., IS-801 messages, with an IWLG located in the home network. Via the messaging, the mobile node provides certain parameters which the IWLG uses to determine which network the mobile node is roaming. The IWLG interfaces with the appropriate network elements in the visited network to determine the location of the mobile node.

Abstract: The invention increases billing options for a wireless service provider by allowing the provider to make billing decisions based upon what a client or mobile station application does both on and off the network. This type of billing, based on context, generates a billing record of events whether or not a particular client accesses the wireless network or not. The invention also provides transmission quality data allowing the wireless network provider to improve user experience in a wireless network. The invention captures the context, including content, quantity, and/or quality of data processed by a mobile station using a client-based application rather than a network-based application. The client-based application causes the mobile station to transmit a billing record corresponding to the captured context to a user monitoring server. The user monitoring server processes the billing record for determining billing and for generating engineering reports.

Abstract: Aspects of the invention allow mobile network users as well as mobile network providers to define policies that are managed across several applications and services. Thus, several application servers and network elements are coordinated to implement a service policy. More specifically, aspects of the invention define service level policies for any service be within an IMS based or non-IMS based wireless network implemented by SIP or non-SIP network elements. A service policy is a set of rules that is applied when a subscriber uses a specific service (Web Browsing, Location, Presence, MMS, SMS, PoC, etc). The policy may be applicable on a per-need, per-subscriber basis. A service policy enhances or restricts use of the service functionality by the subscriber. A service level policy should also allow definition of service utilization rules that constrain how the service may be used by the subscriber.
