Abstract: A method for maintaining IP context during an inter RAT handover of a UE between an eHRPD network and an LTE network may include delaying a transfer of an Internet Protocol context for at least one active packet data network until an IP address for an attach (PDN) Packet Data Network has been assigned and in the case where the Internet Protocol address for the Attach Packet Data Network is not assigned, initiating a detach operation from the LTE network without the user equipment losing the Internet Protocol context of the at least one active Packet Data Network.

Abstract: Techniques for maintaining an always-on data session for an access terminal are described. Messages to keep alive the data session may be sent using non-traffic channels to avoid bringing up traffic channels just to send these messages. In one design, an access network may send a first message (e.g., a RouteUpdateRequest message) on a first non-traffic channel (e.g., a control channel) to the access terminal. The access terminal may return a second message (e.g., a RouteUpdate message) on a second non-traffic channel (e.g., an access channel) to the access network. The access network may then send a third message (e.g., for an Echo-Request) on the first non-traffic channel over a smaller area covering an approximate location of the access terminal, which may be determined based on the second message. The access terminal may return a fourth message (e.g., for an Echo-Reply) on the second non-traffic channel to the access network.

Abstract: Systems and methods for automatically providing different levels of Quality of Service (QoS) to applications in a communication network having various content providers. Typically, content is provided to applications that are unable to specify applicable QoS. A service node is provided to coordinate transfer of data to the applications. The service node further cooperates with an access terminal running the applications to specify the QoS.

Abstract: Apparatus and methods are disclosed for power optimization in a wireless device. The apparatus and methods effect monitoring the amount of data stored in a data buffer that buffers data input to and data output from a processor. Dependent on the amount of data stored in the buffers parameters of a control function, such as a Dynamic Clock and Voltage Scaling (DCVS) function are modified based on the amount of data stored in the data buffer. By modifying or pre-empting the parameters of the control function, which controls at least processor frequency, the processor can process applications more dynamically over default parameter settings, especially in situations where one or more real-time activities having strict time constraints for completion are being handled by the processor as evinced by increased buffer depth. As a result, power usage is further optimized as the control function is more responsive to processing conditions.

Abstract: A method for inter-modem coordination is described. A first data connection to a network in a first network coverage area using a first air interface provided by a first modem is established. The method also includes detecting a second network coverage area with a second air interface provided by a second modem. A data call state of the second modem is determined by the first modem. The first data connection to the network by the first modem is terminated when the data call state of the second modem is no data call. A data call state of the first modem is determined by the second modem. A second data connection to the network using the second air interface provided by the second modem is initiated when the data call state of the first modem is no data call.

Abstract: Techniques for managing resources on a wireless device are described. In an aspect, congestion of resources on the wireless device may be detected. If any resources are deemed to be congested, then congestion of the congested resources may be relieved by controlling utilization of the congested resources by at least one client. In one design, flow control may be performed for at least one data flow to relieve congestion of the congested resources. A pattern indicative of when to send messages enabling data transmission and when to send messages disabling data transmission may be selected. Messages may then be sent in accordance with the pattern to control transmission of data for the at least one data flow. Another pattern with a higher ON fraction or a lower ON fraction may be selected based on usage of the congested resources.
