Abstract: A distributed test equipment system for testing analog communications systems. One or more analog signal receivers and one or more computers are connected via a packet-switched network such that each computer can remotely control and receive signal data from each receiver. Analog signal data measured by each receiver is available for relaying to each computer where it is processed for analysis in conformance with respective user commands.

Abstract: A user uses a wireless communication device to engage in a communication session over a packet-switched network. The communication session is one of a plurality of different session types, e.g., a push-to-talk (PTT) session or a Web browsing session. The user is identified in the communication session by a user identifier that is dependent on the session type. The user identifier used in a particular communication session is included in a usage record generated for that communications session. A billing system determines the session type from the user identifier in the usage record. Based on this session type, the billing system selects a billing formula to calculate a charge to the user for the communication session.

Abstract: A wireless switch comprising: a sensor for sensing a change of a state of a barrier; a selector positionable between a first position and a second position; a transmitter operatively coupled to the sensor and selector; and wherein the transmitter transmits a first wireless signal when the selector is positioned in the first position and the sensor senses a change of state, and the transmitter transmits a second wireless signal different from the first signal when the selector is positioned in the second position and the sensor senses the change of state.

Abstract: For a call flow to perform position determination, a network (100) sends to a user equipment (UE) (120) an indication (e.g., a request for permission) to perform a position fix for the UE (120). The UE (120) responds by sending to the network an acknowledgment (e.g., a grant of permission) to perform the position fix. The UE (120) selectively sends a position estimate for itself to the network (100), typically along with the acknowledgment. The network (100) may initiate location processing if (1) a position estimate is not received from the UE (120) or (2) a position estimate is received from the UE (120) but the network (100) decides not to use this position estimate. In this case, the network (100) and the UE (120) perform location processing to obtain a position fix for the UE (120). However, if a position estimate is received from the UE (120) and the network (100) decides to use the position estimate, then the location processing is bypassed or short circuited.

Abstract: A method and system for actually identifying a source of real-time media within an RTP stream. A sending node such as a client station or conference server inserts into an RTP header of at least one packet of the RTP stream an actual identification of the media source, such as a text representation of the name or e-mail address of a user who provided the media or a phone number of the station that provided the media. For instance, the sending node could insert the actual identification into an RTP header extension. A receiving node can then receive the RTP stream, read the actual identification from the RTP header, and present the actual identification to a user while playing out the underlying media to the user.
