Abstract: Devices, softwares and methods enable SIP devices to operate in H.323 networks, and devices, softwares and methods enable H.323 devices to operate in SIP networks. Messages that initiate communication from a first protocol are translated into the appropriate messages of the second, responded to, and the replies are translated back into the first. Routing by the legacy network is thus seamlessly exploited.

Abstract: In one embodiment, a carrier-managed system such as the cellular network or the Global Positioning System (GPS), is leveraged to directly determine or triangulate geographic locations of the dual mode device and then the access point. Advantageously, a service provider may constantly and automatically update its database with the geolocation of APs and associated devices to thereby provide accurate information and improved emergency services.

Abstract: A call authorization system moves state maintenance for authorization based phone calls from a central authorization server to different gateways in a packet switched network. A simple authorization session protocol is used between the authorization server and the gateways to minimize network traffic. The authorization session protocol releases the authorization server from having to maintain states for open authorization based phone calls.

Abstract: A system and method provide for managing presentation delay for presenting media or control information to participants in a multimedia experience. Embodiments provide for determining whether a presentation timing for presenting information to the participants is calculated to correspond with a predetermined presentation timing relationship, and if the presentation timing is calculated to conflict with the predetermined presentation timing relationship, determining one or more delay modifications that are calculated to cause a presentation timing to the participant to correspond with the predetermined presentation timing relationship, and causing the modification to be implemented.

Abstract: A network processing device is signaled to establish a media path with another network processing device in a packet switched network with Session Initiated Protocol (SIP), International Telecommunication Union (ITU) standard H.323, MGCP, Megaco, or some other signaling protocol. The network processing device receives a request to send information to an observer device that is not directly in the media path. The network processing device then sends information about the media path to the observer device.

Abstract: A service grammar can be defined in Backus Naur Form for a protocol. The service grammar can be compiled into a service analyzer, which can identify services from a trace of messages sent using the protocol. Similarly, a workflow grammar can be defined for services implemented using the protocol (a meta-grammar). The workflow grammar can be compiled into a workflow analyzer, which can identify workflows from the services (and therefore, indirectly from the trace). This workflow information can be used to define actions for a User Agent (UA) that can act on behalf of a person. The UA can be validated using the service analyzer and workflow analyzer to verify that the UA is acting correctly.

Abstract: Media that is normally packetized into many separate individual packets and then queued for individual transmission during a transmit window is combined together into one, or a few, packets. The larger packets more efficiently carry media over a time slotted communication media since only one, or a few, packet headers are used for carrying a larger amount of media. Since packets cannot be transmitted until the start of a new transmit window, the larger packets do not substantially add to the overall packet delay that normally occurs when larger packets are formatted and transmitted in non-time slotted networks. In another aspect of the system, probe packets are used to identify the start of the transmit window. The transmit window start time is inferred from the round trip times for the probe packets and media packetization is then synchronized with the identified transmit windows.

Abstract: A communication system quarantines text and then automatically transmits the text across a network at the end of a quarantine time period. This text quarantine period gives a user the chance to edit or delete text for a brief amount of time after the text has been entered. This allows editing or deletion of spelling errors, and inadvertent or indiscriminate text responses before the text is sent to a remote user. Since the text characters are automatically transmitted after the quarantine period, normal human communications and interactions are maintained allowing a receiver to interject or interrupt with text comments in the middle of a received text message. Thus, the communication system maintains the interactive advantages of TTY/TDD systems while also providing the editing flexibility of instant messaging systems. In another aspect of the text system, characters are buffered until they form a complete expression.

Abstract: In accordance with a particular embodiment of the present invention, a method for providing privacy protection to network users includes receiving a subscription request from a first end user. The subscription request identifies a second end user for whom the first end user would like to become a registered presence watcher. A cost to be assessed to become the registered presence watcher of the second end user is determined, and the first user is registered as the registered presence watcher of the second end user.

Abstract: In accordance with a particular embodiment of the present invention, a method using presence information to manage network access includes maintaining presence information for an end user. When a remote access request is received from the end user at a remote endpoint, the presence information for the end user is updated to identify the presence of the end user at one or more network endpoints associated with a private network. An access point to the private network is then automatically configured to allow any communications addressed to an IP address associated with the one or more network endpoints to pass through the access point.

Abstract: In accordance with a particular embodiment of the present invention, a method using shared configuration information to manage network access for externally generated communications includes maintaining association information for a first end user of a private network and maintaining configuration information for a first endpoint associated with the first end user. When an externally generated communication that is addressed for delivery to a second endpoint associated with a second end user is received at an access point to the private network, the association information is used to determine an association between the first end user and the second end user.

Abstract: In accordance with a particular embodiment of the present invention, a method for providing security information associated with a prospective communication session to a user includes providing at least one communication network for the establishment of a prospective communication session between a first network device and a second network device. A security rating is assigned to the prospective communication session, and security information is provided to a user associated with the first network device that includes the security rating.

Abstract: In accordance with a particular embodiment of the present invention, a method using Quality of Service (QoS) information to influence a user's presence state is provided that includes the establishment of a virtual communication session between a first network device and a second network device. The virtual communication session emulates a communication session that may be established in the future. At least one QoS parameter associated with the virtual connection is monitored. Presence information is then provided to a first user that includes the QoS parameter.

Abstract: The present invention relates generally to a system and method of managing a Push To Talk (PTT) conversation while the recipient is watching television. PTT messages may be conveyed by an initiator to a recipient through the use of a telephone connected to a network. The network is also connected to either a set top box (STB) or a Digital Video Recorder (DVR). Within the network resides a presence state machine, which determines if a PTT conversation may be initiated. Upon initiation of a PTT conversation the presence state machine may pause the television by a command to the STB or DVR. If the television has been paused, upon termination of the PTT conversation, the presence state machine instructs the STB or DVR to resume television display.
