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.

A method for applying a differentiated Quality of Service (QoS) to a payload using a profile indicator that can identify or be used to identify portions of the payload having different QoS requirements. The profile indicator may be one or more length indicators for indicating the lengths of each portion of the payload, or it may be an index to a table which indicates the lengths of each portion of the payload. The table can be used to map the profile indicator to a number of portions in the packet, the lengths of each portion and a QoS requirement for each portion.

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.

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.

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.

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.
摘要:
A conventional keyboard-style ACPI interface is greatly enhanced by the inclusion of a bi-directional hardware buffer and a special software protocol that allows multiple byte command and data messages to be sent in a burst fashion. The illustrative enhanced ACPI interface alleviates congestion in data transmission that results from the overhead incurred by transferring messages using multiple interrupts per message. An extended embedded controller includes a buffer for temporary storage of a plurality of data bytes and a program code for controlling data transfers to and from the buffer using a data handling technique that is ACPI-compliant.
