摘要： Disclosed is a method and system for performing handoffs in a wireless communications network which incorporates Voice over Internet Protocol (VoIP) using shared supplemental spreading codes. In this method and system, a mobile station is assigned a first and second primary code and a first and second set of supplemental codes. The first primary and set of supplemental codes are associated with a first base station. The second primary and set of supplemental codes are associated with a second base station and assigned to the mobile station when the mobile station is entering into a handoff state. The first and second set of supplemental codes belong to a pool of shared supplemental codes associated with the first and second base stations, respectively. A specific supplemental code is assigned from each of the first and second sets of supplemental codes when a complete packet cannot be transmitted over a single transmission time interval on the first and second primary channels. Each of the specific supplemental codes must be currently available before it could be assigned. Mapping tables may be used to associate assigned specific supplemental code indicators to specific supplemental codes belonging to the first and second set of supplemental codes. The mapping tables may be Transport Combination Format (TFC) mapping tables, and the assigned specific supplemental code indicators may be Transport Combination Format Indicators (TFCI). A single TFCI or equivalent may be used to indicate a same or different supplemental code at each of the first and second base stations.

摘要： Disclosed is a method and system thereof for transmitting a Voice over Internet Protocol (VoIP) packet over a primary channel and a supplemental channel belonging to a shared pool of supplemental channels in a wireless communications network such that Orthogonal Variable Spreading Factor (OVSF) codes associated with higher spreading factors (SF) may be used, thereby minimizing the adverse effects on system resources associated with implementing VoIP over downlink Dedicated CHannels (DCH). In the method and system, if an entire VoIP packet cannot be transmitted over a single transmission time interval on a primary channel, a specific supplemental channel (or code associated therewith) is assigned to a User Equipment (UE) to which the VoIP packet is intended. A portion of the VoIP packet is transmitted to the UE over a Dedicated Physical Data CHannel (DPDCH) on the primary channel, and another portion of the VoIP packet is transmitted to the UE over a DPDCH on the supplemental channel. The assigned specific OVSF code (or supplemental channel associated therewith) belongs to a set of supplemental OVSF codes assigned to the UE, and the set of assigned supplemental OVSF codes belongs to a shared pool of supplemental OVSF codes reserved at Node B. The identity of the assigned specific supplemental OVSF code used for the supplemental channel is indicated to the UE over a Dedicated Physical Control CHannel (DPCCH) on the primary channel. The UE examines the DPCCH on the primary channel to determine whether a specific supplemental channel (or code associated therewith) has been assigned to it. If a specific supplemental channel was assigned, then the UE will decode the data on the assigned specific supplemental channel along with the data on its primary channel. Otherwise, the UE will only decode the data on its primary channel.

摘要： In a UMTS wireless communication system, the enhanced dedicated physical control channel (E-DPCCH) that is usually always transmitted together with the enhanced dedicated physical data channel (E-DPDCH) on the uplink from a UE to a NodeB is instead only transmitted when a predetermined “start criterion” is met and is turned off when a predetermined “stop criterion” is met until a “start criterion” is later met again. The UE starts transmitting E-DPCCH whenever the corresponding E-DPDCH transport format combination is different from the previous one in the same HARQ process or some other “start criterion” is met. Multiple mechanisms can be used to decide when the UE should switch off E-DPCCH transmission after the transport format combination of E-DPDCH has changed.

摘要： In a UMTS wireless communication system, when the packet size on the enhanced dedicated physical data channel (E-DPDCH) on the uplink from a UE to a NodeB reaches a converged default packet size, the corresponding dedicated physical control channel (E-DPCCH) is turned off. The NodeB uses the default packet size to decode the frame received on the E-DPDCH using each possible redundancy version. Alternatively, the E-DPCCH is turned off and a new transmission flag is transmitted by the UE only when a new frame is transmitted by the UE. NodeB then uses the presence or absence of that flag in conjunction with the absence of E-DPCCH to determine which redundancy version is to be assumed in decoding the frame received on E-DPDCH.

摘要： In a UMTS wireless communication system a UE autonomously determines that it is going to transit from an active traffic mode into an idle traffic mode and informs the NodeBs in its active set that it is doing so. It does so either by using Layer 1 signaling, using the uplink DPCCH to send a message to the NodeBs indicating the transition, or by using Layer 2 signaling by via MAC PDUs that contain the message, which are delivered on the uplink E-DPDCH to the NodeBs.

摘要： A host computer system is configured to present each of multiple resident contexts with an address space that may be mapped, at least in part, to corresponding portions of a host memory. The address space of a selected context is sampled, and, for each of a plurality of sampled portions of the address space of the selected context that are backed by a corresponding portion of host memory, a count of the number of portions of address spaces of any contexts that are backed by the same portion of the host memory is obtained. A metric is then computed as a function of the count. A decision about swapping out or reclaiming the allocation of the memory of the contexts is based on the metric. The metric is preferably a function of a mean (such as harmonic, geometric or arithmetic) or median of the counts for each context.

摘要： A system and method is disclosed in which the buses and physical characteristics of a server computer are monitored through server management software. A data structure for a monitored characteristic or group of characteristics is created and stored in a repository of data structures for other monitored devices and attributes within the server computer. As events, such as failure and pre-failure events, occur on one or more of the monitored attributes, the event is recorded in an event log. Using the server management software, monitoring commands can be issued by the baseboard management controller to each monitored bus to check the status of the attribute or device.

摘要： A method and system for providing Voice over Internet Protocol (VoIP) in a wireless communications system using a Packet Data Conversion Protocol (PDCP) with enhanced functionality that allows sub-packets to be processed for transmission over different Radio Bearers (RB) with unequal or different levels of error protection and/or error detection based on perceptual importance of the bits in the sub-packets. The enhanced PDCP being operable to partition a packet into a plurality of sub-packets such that different levels of error protection and/or error detection may be applied to the packet. An overall gain in system capacity can be expected due to transmit power savings provided via unequal error detection and error protection.

摘要： A method for allocating memory in a computer system is disclosed. The method includes creating a kernel memory class, the kernel memory class acting as a logical container for at least a first kernel memory resource group. The method further includes processing a kernel client's request for additional memory by ascertaining whether there is sufficient free memory in the first kernel memory resource group to accommodate the kernel client's request. The method additionally includes denying the kernel client's request if there is insufficient free memory in the first kernel memory resource group to accommodate the kernel client's request.
