摘要:
A method of conveying a location information representing a physical location of a communication device (1) to another communication device (2) comprises acquiring (6) by the communication device (1) a first location information (11) and a second location information (17), the second location information being acquired (17) subsequently to the acquiring of the first location information (11) and detecting by the communication device (1) a deviation of the second location information from the first location information (18) representing a change of the physical location of the communication device (1). The method further comprises, triggered by the detected change of the physical location of the communication device (1), conveying (27) the most recently acquired physical location of the communication device (1) to the other communication device (2) by sending (26) a signaling message by the communication device (1) to the other communication device (2), the signaling message comprising either the second location information or the deviation of the second location information on the first location information.
摘要:
Using a method for a subscriber unit's communication with a service that requires information about the subscriber unit's location, the subscriber unit sends the service a message containing information about the subscriber unit's location and at least one piece of information about the subscriber unit's location is stored in at least one network component and is made available by a network component.

Disclosed is a method for managing data in a communication network (10) comprising a connection (20), in particular a switch, and at least one local communication terminal connected to the connection device (20). The connection device (20) is connected to or equipped with a second management information base (MIB′), in which information related to the location of the communication terminal is written and is made available for use in a location-dependent service during a data management process, the location-dependent service being designed according to a discovery protocol. The data management process involves feeding the location-related information to the communication network (20) using a location information source (3) and transmitting the fed location-related information from the location information source (3) to the connection device. Across at least one section of the transmission path, the fed location-related information is transmitted according to the discovery protocol.

摘要:
A location information (li) which is available in a mobile terminal device (ME-T) and which indicates the geographical location of the terminal device (ME-T) is embedded in messages (m) of a SIP protocol (SIP) which are exchanged between the terminal device (ME-T) and the network (WLAN) during the establishment of a session and/or during a session and/or during the registration of a terminal device (ME-T) in the network (WLAN), e.g. LAN or UMTS, or during request of a service or a function. By advantageously complementing the SIP protocol (session initiation protocol), the location information can be transmitted from a mobile terminal device (ME-T), which optionally has a telephone function, to the network (WLAN) in any signaling state, thereby substantially reducing the economic outlay for implementing the transmission of location information (li) to the network (WLAN).
摘要:
Transmission parameters for the transmission of at least one ticker information (ti) are transmitted during signaling of the transmission parameters for at least one multimedia data stream (mmd) for a session (S), the parameters establishing an additional logical transmission channel for the transmission of ticker information (ti), specifying the transmission protocol (RTP) and the payload type (555,666, 777,888) and inserting a source information which shows the source of the ticker information (ti). A session description protocol (SDP) embedded in a session initiation protocol (SIP) is used to describe and administer the transmission parameters. The invention allows the signaling for the additional information or ticker information (ti) to be implemented into existing network protocols for packet-oriented networks with only minor additional signaling and transmission operations.
摘要:
There is described a system for switching from an established media path to a new media path for packets transmitted between first and second end points in a packet based network. An instruction is transmitted to the first end point instructing it to set up a new receiving channel for receiving packets transmitted from the second end point over the new media path. An instruction is transmitted to the second end point instructing it to configure a sending channel to send packets over the new media path for reception on the new receiving channel of the first end point. For a time period during the switching, the first end point monitors for packets simultaneously on both its new receiving channel and an established receiving channel configured to receive packets transmitted from the second end point over the established media path. This systems helps ensure a seamless switchover from the established to the new media paths.

摘要:
A method for transmitting on-demand software and/or data from a server to a terminal in a packet network is provided. According to the method, a bandwidth test is performed as a prerequisite for transmission, said test verifying whether the currently available bandwidth is sufficient for transmitting the requested software or data. The server does not transmit the requested software or the requested software or the requested data if the results of the bandwidth test is negative.
摘要:
Method of transmission of data between at least two communication devices which are connected together over a data network. The communication devices are respectively connected to a coding device and the sent data are source-and channel-coded by a coding method respectively furnished within the coding devices. The data are converted within a converting device connected to the data network.
