摘要:
The invention provides persistent communication for address routed communication in an environment where the communication session address changes. The invention is appropriate for any address routed communication, and in particular to packet based (e.g., UDP/IP and TCP/IP) communications to mobile cellular units as the units transition or move between supporting cells. The invention provides a technique to store address information and transitory information related to the session to allow continuation of the session at the new address, thereby reducing or eliminating the need to set up the session at the new address. One application is for streaming multi-media sessions. Another application is for internet protocol (IP) telephony. The invention provides embodiments where the techniques are performed within the mobile unit, or performed in combination with a proxy server that is part of the supporting cellular system.

A servlet-based architecture for dynamic service composition in which service configuration information is received through a communication network. A service template file, including service configuration request information, may be sent to a user and a service configuration response, including the service configuration information, may be received from the user through the communication network. Software components are dynamically selected and configured, based on the received service configuration information, to create a software-based service. The software-based service may then be executed on a server to provide the service for the user.

A modem concentrator is provided that creates network-initiated connections to users of the network. According to the method, active downstream data is received from a data network at one data port. A controller of the modem concentrator reads the active downstream data and compares recipient information contained therein with stored identifiers of users. The identifiers are stored in association with identifiers of a user-side port to which the modem concentrator is connected. The controller identifies another data port associated with the identified recipient and causes a connection to be made between the one data port where the downstream data is received and the other data port connected to the user. The modem concentrator provides a use-once registration feature. When the concentrator processes upstream data, data from a user to be delivered to the network, it reads the upstream data to identify source information identifying the user that generated it. It stores the source information for use in later network-initiated connection attempts.

A customized advertising repository server is connected on the World Wide Web (WWW), which can be accessed by a registered user through his or her browser either by clicking on an icon, or by inputting the specific URL address of the particular server which stores that user's advertising repository. When the user accesses his or her customized ad repository through the browser, a composite advertising page is dynamically configured by the Customized Advertising Repository (CAR) server for that particular user based on that user's previously provided user profile. Furthermore, at least a portion of that composite advertising page can be dynamically configured on a context dependent basis determined from the particular Web site or sites that the user has accessed prior to accessing the CAR. The dynamically configured composite page or pages of advertising provided to the user may contain plural static images, streaming banners, 3-D images, animation, video and/or audio clips, using any of the technologies available on the Web for presenting textual and/or visual information. Such a composite page or pages is configured from a database which stores such images, banners, animation, etc., from plural advertisers. The customized page is created by selecting from among a storehouse of plural different subscribing advertisers and their associated banner ads, images, etc., those particular images, etc. that will be elements of the customized page based on the user's specific areas of interest as determined from the profile, and/or the context dependency. From such dynamically configured composite page or pages, the user can then click on a particular image, video window, banner, etc., to retrieve, through a hyperlink, further information directly from the selected advertiser's own Web site or mirror Web site.
摘要:
This invention provides a more effective method for capacity planning and traffic engineering of packet networks that connect Virtual Private Network (VPN) sites. A distributed architecture efficiently computes traffic matrixes that show the number of bytes and/or packets exchanged among provider edge (PE) routers and/or service nodes. Each PE router in a service node is exports flow records to a Flow Record Processor (FRP) in the same location. The FRPs use these records in conjunction with configuration data extracted from the PE routers to compute partial traffic matrixes. The partial traffic matrixes are uploaded to a Matrix Generator to create a total traffic matrix. The total traffic matrix is essential input for capacity planning or traffic engineering tools.

A method of delivering and minimizing duplication of multimedia content to users in pervasive computing environments is disclosed. A mobile device enters a first environment and establishes a short-range wireless connection to a non-mobile device in its proximity. The non-mobile device transmits metadata as it displays content. The metadata is received by the mobile device and stored in a local buffer. The mobile device accumulates a viewing history of content that has recently been viewed. The mobile device later enters a second environment and establishes short-range wireless connection to another non-mobile device. The viewing history is transmitted from the mobile to the non-mobile device and is used to select and sequence content.

An enhanced network element and method for configuring and deploying computer network elements is disclosed. A customer orders a network element from an equipment provider. Upon receipt of the unconfigured network element, a Trusted Configuration Device (TCD) is shipped from a network provider to the customer. The TCD transmits information to the NE that enables it to download a configuration file from a Provisioning Server (PS) via a secure channel.

摘要:
The provisioning of enhanced 911 service in a mobile communications network is supplemented to include the capability of identifying other mobile stations in close proximity to a mobile station placing a 911 call. This capability may then be used to aid in the identification of witnesses to a crime, car accident, and the like. Constantly updated location information for mobile stations in communication with a switching center is maintained in a database that can be accessed by PSAP agents on an “as needed” basis. In particular, a PSAP agent can submit a search request, using time/date and geographic location information to determine the identity of all mobile stations in a predetermined “radius” associated with a 911 caller.
