  • Publication number: 20070116220
    Abstract: A method and a system for representing the attributes of an incoming call are disclosed. A determination module is used to determine certain attributes of an incoming call. The attributes can be the caller ID, urgency of call or call location, among others. The determined attributes are then converted into an audio-tone that is representative of the incoming call. Characteristics, such as pitch, volume and cadence of the audio-tone are chosen to represent the attributes of the incoming call.

  • Publication number: 20070116006
    Abstract: A method for communicating data in a network environment is provided that includes receiving a request from an end user for a communications link, the request being used to initiate a communication session. A response is then received that is communicated to the end user in order to establish the communication session, the response being generated by a network node that was selected as a result of a loadbalancing decision. Port-level filtering for the communication session may then be invoked after the response such that separate data and signal pathways are established for selected information associated with the communication session.

  • Publication number: 20070116237
    Abstract: A system includes a computer workstation associated with an agent of a call center and a subsystem that includes automatic call distributor (ACD) functions for connecting a caller to the computer workstation of the agent, the subsystem being connected with a device of the caller via an Internet Protocol (IP) network. The agent transmits a first message over the IP network to a device of the caller during the call. The first message contains notes electronically recorded by the agent. Prior to or coincident with an end of the call, the caller sends a second message back to the system confirming the agent's notes. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

  • Publication number: 20070118670
    Abstract: A method of load balancing network access requests comprises receiving a network access request from a serving node linked to a radio access network. The network access request identifies a mobile node receiving wireless service from the radio access network and identifies a data network to which the mobile node has requested access. The network access request requests a communication channel with the serving node for transporting data communications between the mobile node and the data network. The method further comprising determining one or more gateways providing access to the data network, selecting one of the gateways, and forwarding the network access request to the selected gateway.

  • Publication number: 20070115963
    Abstract: A Real-Time Protocol (RTP) source node of a network operates to send a first data packet of a first size to a destination node over a path of the network that includes a plurality of intermediate nodes, at least one of the intermediate nodes having a maximum transmission unit (MTU) size smaller than the first size such that fragmentation of the first data packet occurs. The destination node sends back to the source node a RTCP report that includes a number of fragments received and a largest minimum data packet size. In response, the source node sends subsequent data packets having a second size less than or equal to the largest data packet size of the fragments. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

  • Patent number: 7222333
    Abstract: Techniques for forming an application from a particular file that has source code in a particular language include receiving, from the particular file, comment data. The comment data is ignored according to the particular language. The comment data includes build data indicating how to use the source code in a build process. The build process packages compiled code to form the application. Based on the build data in the comment data, build-input data is generated. The build-input data indicates input for the build process. These techniques automatically provide, for the application build process, build information known to the application developer who produced the source code.

  • Patent number: 7221712
    Abstract: Methods and apparatus are provided for determining transmission power levels. The power characteristics of a cable modem family are determined by testing cable modems in a cable modem family with various downstream frequencies and transmission power levels to determine internal gain levels. The power characteristics of the cable modem family can then be stored in an efficient manner in each cable modem by using interpolation. The individual cable modem can then be characterized by testing the cable modem with a limited set of downstream frequencies and transmission power levels to determine an internal gain level offset for that particular cable modem. With the power characteristics table, internal gain level offset, and interpolation, transmission power levels can be determined during network operation when downstream frequencies and internal gain levels are known.

  • Patent number: 7221750
    Abstract: Methods, apparatuses, and systems directed to managing wireless node access to one or more wireless networks. According to one implementation, a business logic application may function as a package tracking application to manage access to wireless access points in different WLANs along the route. A sensor node is initialized and configured with one or more connection parameter sets allowing it to associate with a given wireless network implemented by one or more access points. In one implementation, the sensor node is configured only to accept received wireless frames that it can properly decrypt using the currently stored encryption key. When the sensor node and such a wireless access point associate, they may exchange encrypted information (e.g., data regarding the package) using an encryption key. Before the sensor node disassociates with time wireless access point, the wireless access point transmits a new connection parameter set to the sensor node.

  • Patent number: 7222185
    Abstract: A system controller selects a transmission mode for content distribution based upon the relative popularity of the content within the content distribution system. The system controller receives a content distribution request from a content source and detects a content distribution characteristic for content to be distributed by the content source, in response to receiving the content distribution request. When the content distribution characteristic indicates the content as being relatively popular, or frequently requested by receivers in the content distribution system, the system controller selects a one-to-many transmission mode for the content. When the content distribution characteristic indicates the content as being relatively unpopular, or infrequently requested by receivers in the content distribution system), the system controller selects a one-to-one transmission mode for the content.

  • Patent number: 7221684
    Abstract: A communication device for compressing packets includes a first interface, a grouping module and a second interface. The first interface receives packets from a group of media streams, the grouping module generates a group packet that includes a group identifier as well as the payloads of the packets, and the second interface communicates the group packet for receipt by a remote device. A communication device for decompressing packets includes a memory, an interface, and a processor. The memory stores state information for a group of media streams, the interface receives a group packet carrying payloads from the media streams, and the processor reconstructs the headers of the packets using the state information.
