Method and apparatus for prolonging battery charge life in a mobile communication device using a text messaging type protocol for calls
A wireless telecommunication device conducts base station pages at large intervals, such as 30 seconds, rather than the more conventional 0.5 to 4 seconds. The network processes calls placed to that telecommunication device in accordance with an SMS (Short Messaging Service) type protocol rather than a conventional voice call protocol.

Methods for efficient implementation of skip/direct modes in digital video compression algorithms
The approach of the present invention is to take advantage of similarity in implementation between SKIP and DIRECT modes and one other inter-picture prediction modes, namely, the 16×16 partition mode. The SKIP/DIRECT modes are classified into two groups, one involving inter-picture prediction in one temporal direction in which prediction is chosen from either past or future recon pictures, and the other involving prediction in two temporal directions in which prediction is constructed as a superposition of both past and future recon pictures. The first group requires interpolation for only one direction, whereas the latter requires interpolation for both directions, thus requiring roughly twice as much data processing power than the first group. The 16×16 partition mode also allows both prediction schemes, either past or future, or a superposition of past and future. The SKIP/DIRECT and 16×16 partition modes all apply the same motion vector on the entire block unit.Methods of the present invention consider the SKIP/DIRECT modes if and only if the final prediction information of the 16×16 partition mode, including motion vector, reference picture index, and prediction direction, is the same as that of the respective SKIP and/or DIRECT modes. The point here is that the same motion prediction, reference picture index and prediction direction are used for the 16×16 partition mode and the SKIP/DIRECT modes, and therefore, the same interpolation scheme can be used for both SKIP/DIRECT and 16×16 partition modes, thus saving computational cost as well as implementation cost.

If a threshold network CQICH capacity is reached during a subsequent data frame such that a CQICH is no longer available, MAC level messages are generated between the BS and the particular user to trigger reporting of signal quality information to the BS by the particular user. After the next CQICH cycle commences and if a CQICH is still unavailable, the signal quality information is continued to be provided via MAC level messages. Otherwise, a CQICH is reallocated for a particular user and channel quality measurement reporting is transitioned back to the CQICH.
Method and system of multimedia service performance monitoring
A method and system of multimedia service performance monitoring is provided. The method comprises the following steps: (a) a reference point acquires and stores the association relationship between multimedia packet identification number and the corresponding multimedia information; (b) a sample point orders the received packets according to the multimedia packet identification numbers, detects the integrality of the packets, and feeds the identification numbers of the lost multimedia packets back to the reference point if there are lost packets; (c) the reference point obtains the corresponding multimedia information according to the identification numbers of the lost multimedia packets returned by the sample point and the stored association relationship between the multimedia packet identification number and the corresponding multimedia information, and then evaluates the multimedia service quality of the sample point.
Content transfer between nodes in a communications network is required in many situations. For example, between fixed nodes in a data center, between a fixed node such as a base station and a mobile node such as a mobile telephone and between mobile nodes themselves such as personal digital assistants. In an embodiment a content transfer process for use between nodes where one node knows the size of content to be transferred is described. For example, a file is divided into blocks to be sent between the nodes. A node receiving a block keeps a record of the received blocks and sends that record to the sending node at certain times. By controlling the times at which the records are sent the number of messages that need to be sent to transfer the records is low and the blocks are transferred in an efficient manner.
Fast SSL testing using precalculated cryptographyc data
Methods and computer readable storage media to test secure network connections. One or more pre-calculated encryption data (PCCD) sets may be defined in accordance with a secure communications protocol. The one or more PCCD sets may be stored in a first PCCD memory and a second PCCD memory located respectively within a first port unit and a second port unit of a plurality of port units. Each PCCD set may include at least a first parameter and a second parameter generated by encrypting the first parameter. A simulated secure connection between the first port unit and the second port unit via a network under test may be opened using a selected PCCD set from the one or more PCCD sets without performing decryption processing.
Method of securing network access radio systems
A method of providing security for network access radio systems and associated access radio security systems used with the systems. The method includes connecting an access radio having a radio link to a network; communicating between the access radio and a computer over the network using a ping application having ping commands and unique encrypted codes; and enabling operation of the access radio when the access radio is receiving ping commands. Typically, the access radio and the computer are nodes on the network and the network is a local area network (LAN). The ping application sends packets of information from the computer to the access radio and receives a response from the access radio. The ping application must be functioning (i.e., sending and receiving commands between the computer and the access radio) to enable the access radio to communicate via the radio link with a remote network.
Methods, systems and computer readable media for mobile-communication-device-initiated network monitoring services
Methods, systems, and computer readable media for mobile communication device-initiated network monitoring services are disclosed. According to one aspect, a method for monitoring communications in a mobile networking environment by a core network probe-based monitoring system includes detecting, by an agent residing on a mobile communication device, a quality of service or customer experience triggering event; responding to the event by generating a message which includes information about that particular subscriber or device; and, transmitting that message to the network monitoring system to automatically trigger the monitoring system to monitor communications involving that mobile communication device.
Method for processing telephony sessions of a network
A method for processing telephony sessions of a network including at least one application server and a call router, the method including the steps of assigning a primary Uniform Resource Identifier (URI) and at least a secondary URI to an application; mapping a telephony session to the primary URI; communicating with the application server designated by the primary URI using an application layer protocol; receiving telephony instructions from the application server and processing the telephony instructions with the call router; detecting an application event; and upon detecting the application event, communicating with the application server designated by the secondary URI.
Method and apparatus for sending and receiving channel quality indicators (CQIs)
A method and apparatus for sending and receiving channel quality indicators (CQIs) is disclosed. A CQI may be sent or received periodically. A CQI may also be sent or received upon request by a network.
System and method for providing a stable and tamper proof communication between a vehicle, a vehicle related unit, and a remote system
Systems and methods for providing a stable communication between a vehicle's on-board connectivity layer include at least one vehicle located communication node and at least one vehicle associatable communication node, and an off-board connectivity layer including at least one remote system located communication node, wherein each communication node communicates with at least one other communication node over a communication connection, and in case the communication connection to the at least one communication node is disturbed or interrupted, a communication connection to another communication node is established.
