Abstract: More seamless handoff between access networks is achieved by saving session information for each access network upon being handed off from the access network and invoking the saved session information upon being handed back to the access network. An access terminal establishes a first session with a first access network, which may entail performing QoS negotiation with the first access network and setting up packet filters at a packet data gateway. The access terminal exchanges data with the first access network in accordance with the configuration of the first session. The access terminal saves the first session configuration after being handed off to a second access network, establishes a second session with the second access network, and exchanges data with the second access network in accordance with the configuration of the second session. The access terminal uses the saved first session configuration upon being handed back to the first access network.

Abstract: Systems, methods and apparatus for non-optimized handoffs for wireless communication are provided. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network.

Abstract: A broadband service is provided by allocating air interface resources in a wireless network that conforms to the 1xEV-DO standard. The air interface resources are characterized by various quality of service (QoS) parameters, such as bandwidth, packet priority and error rate. Packetized information is transmitted in data flows between a base station and cell phones. A particular QoS level is reserved for each of the data flows that support the broadband service. An operating system on a cell phone monitors one data flow as well as another data flow in the opposite direction. When the base station runs out of an air interface resource, the base station suspends the QoS reservation of a data flow. The operating system determines that the QoS reservation in one direction has been suspended and sends an unsolicited message to the base station releasing the QoS reservation in the opposite direction, thereby conserving network resources.

Abstract: Commonly, when a mobile device tethers to a computer, one Internet Protocol address is provided. When an embedded application runs continuously, such as with a Internet Protocol Multimedia Subsystem application, tethered applications can be prohibited from operating. If the continuous application is not active, then the continuous application can be disconnected and thus the tethered application can function.
