摘要:
An scheduler module is provided for acting on a request to establish a communication session between a first device and a second device, wherein the first device, the second device, or both are associated with a respective activity schedule that specifies, at least in part, a wake-up time when the respective device will be in an active state. The scheduler module also determines whether the first device, the second device, or both are in an inactive state, to determine a next wake-up time to effect establishment of the communication session.

An approach is provided for collaborative context data sensing and communications. A context platform determines context data from a plurality of devices. The context platform processes and/or facilitates a processing of the context data to determine scheduling information for causing, at least in part, a sensing, a transmission, or a combination thereof of additional context data by at least one of the plurality of devices. The context platform then determines the additional context data based, at least in part, on the scheduling information.

A system and method for determining the minimum and/or maximum values from a number of sample parameter values utilizes a table of last occurrence (TOLO-table), together with a sliding window or filter, to greatly enhance the speed and efficiency when determining the minimum and/or maximum value from a number of sample parameter values that fall within the sliding window. The TOLO-table typically includes a parameter column for storing entries for each one of a limited number of discrete parameter values, and also includes a time stamp column which provides entries for storing time of receipt data associated with each parameter value defined in the parameter column. Alternatively, an order number column may be employed for storing number order entries corresponding to the order in which the parameter values are received. Every time a parameter value is received, the time stamp or order number entry associated with the parameter value is updated to the current time or order number. The sliding window may be defined on the basis of time or by a selected number of sample parameter values. The parameter values falling within the sliding window are scanned to determine the minimum and/or maximum of the applicable parameter values. A minimum/maximum determination methodology that employs a TOLO-table and sliding window may be used in a wide variety of applications, and is particularly useful in ATM network applications, particularly in implementing the cell discarding strategy of a network node.

A remaining energy E of a battery is estimated based on a measurement of a momentary voltage and a momentary current. E is defined as a function of its voltage U or power owing to a characteristic function (E/U) or (E/P). Instead of the function, a lookup table can be used. E/U function is defined by using a reference battery having the same or similar characteristics. A set of low and high current or power loads are applied to the reference battery to cause voltage drops which are measured and then used to determine function (E/U) and a parameter Alpha which is specific to the type of reference battery. During the operation of the battery, momentary voltage and current are measured and Alpha is used to correct the momentary voltage. Afterwards, function (E/U) enables to estimate E. The battery size is used to scale E for a better estimation.

摘要:
A system and method for reducing network node congestion by filtering out comparatively low priority packets prior to execution of other node functions, such as routing and switching, in packet-based network transmissions. The volume of packets is reduced by intercepting the information packets prior to their input to the network node. A portion of the intercepted packets are filtered out based on parameters corresponding to a probable packet acceptability at the network node. The remaining portion of the intercepted packets are forwarded to the network node for processing by the network packet functions.
摘要:
A system and method for achieving a comparable quality of service for each of the receivers of a multicast transmission incorporating a priority-based quality of service is provided. Packet acceptance criteria established at each individual connection of a network node is overridden to provide a collective packet acceptance criteria for each packet of a multicast transmission targeted for the individual connections. The packet acceptance criteria is collected from each of the individual connections in the network node that are targeted for the multicast transmission. A multicast packet priority is calculated for each of the packets associated with the multicast transmission based on an aggregate analysis of the packet acceptance criteria of each of the individual connections. Each of the packets associated with the multicast transmission is collectively accepted or discarded based on the calculated multicast packet priority.
摘要:
A system and method for integrating a priority-based quality of service in CDMA communication systems that implement data packet transmission, in order to effectively allocate radio resources. Data packet transfers are selectively allocated over a wireless interface operating under a Code Division Multiple Access (CDMA) protocol. A nominal bit rate is established for each user desiring access to the CDMA interface. A relative packet priority is calculated for each of the data packets based on an actual bit rate at the source of the CDMA interface and the established nominal bit rate. An allowable packet priority is calculated for the CDMA interface based on a signal-to-noise ratio of the CDMA interface, and those of the data packets having a relative packet priority greater than or equal to the allowable packet priority of the CDMA interface are transmitted across the CDMA interface.
