Abstract: The Packet Control Function (PCF) has limited knowledge about the nature of the packet data arriving on a bearer path connected via the Packet Data Serving Node (PDSN), and cannot make an intelligent decision on its own as to how best to handle the packet data. Thus, the PDSN provides bearer-specific information by classifying the priority of received packet data; encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame; and for high priority packet data i) setting a protocol type field in the header of the GRE frame indicating said packet includes an attribute field; and ii) adding an attribute field to the payload of the GRE packet which provides an indication of said high priority data. Furthermore, the PCF can send an A-11 request to the PDSN indicating the features that the PCF is requesting the PDSN enable.

Abstract: Various embodiments provide for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.

Abstract: A dual-mode mobile device comprises two mode systems. If both of two mode systems of the dual-mode mobile device are in a working status, the mobile device uses a first mode system to control a first power amplifier of the first mode system to transmit power signals, informs a second mode system that the first power amplifier is transmitting power signals, and controls the second mode system to enter into a mixed mode. If the second mode system is in a working status and the first mode system is in a required to work status, the mobile device uses the first mode system to inform the second mode system enter into the mixed mode, and controls the first mode system to inform a second power amplifier of the second mode system to transmit power signals causing both of the first and second mode systems to work synchronously.

Abstract: In video quality control and estimation, the joint evaluation of compression artifacts and channel artifacts is a problem. The invention considers the joint perception of both a compression artifact level Dm(V) and a channel artifact level Dh(V) in a method for calculating overall distortion in a video being affected by compression artifacts and channel artifacts. The method comprises a step of adding a compression artifact level Dm(V) and a summand S that is derived from log (Dh(V)) multiplied with a factor that decreases with increasing compression artifact level Dm, such as D(V)=Dm(V)+c·(K?Dm(V))·log(Dh(V)). The result obtained is a measure for the overall distortion.

Abstract: One embodiment pre-builds translations of kernel functions (KFs) and loads them into a translation pool and corresponding indexed table. The KFs are thus quickly loaded and do not necessarily await trapping and emulation via a LIB emulator. This results in faster access to KFs. Other embodiments provide hybrid emulation where some application functions (e.g., those that need quick performance) are translated from a source ISA library while other applications functions are processed via emulation to a target ISA library. Doing so provides faster access to certain functions. Other embodiments are described herein.
