摘要： In some embodiments, a disclosed method involves receiving, by a source gateway, a call request from a source user terminal for establishing a call with a destination user terminal. The method further involves determining, by a source client proxy of the source gateway, a capability related to a parameter(s) of the source user terminal and a capability related to a parameter(s) of the destination user terminal. Also, the method involves sending, by the source client proxy, a call capability offer to a destination gateway based on the determined capabilities. Additionally, the method involves determining, by a destination client proxy of the destination gateway, whether the destination user terminal can support the call capability offer. Also, the method involves sending, by the destination client proxy, a call initiation message to the destination user terminal, when the destination client proxy determines that the destination user terminal can support the call capability offer.

摘要： A method and apparatus for automatically entering information into formatted messages. A communication terminal comprises a receiver for receiving a formatted message, the formatted message comprising a message identification code and a plurality of information fields. A memory contains field-mapping information corresponding to various message identification codes, the field-mapping information indicating which fields of a particular formatted message are to be copied into information fields of a response message to the formatted message. When a response to the formatted message is desired, a processor determines which formatted message to respond to and its corresponding message identification code. A response message is then created, comprising at least one information field, wherein information from one or more of the information fields from the formatted message is copied into the at least one information field of the response message based on the field-mapping information identified by the message identification code.

摘要： A small-sized flat antenna mounted on a portable radio communication device is available for a narrow bandwidth, and the resonance frequency of the flat antenna varies due to interference between the flat antenna and surrounding dielectrics such as a housing and a human body. As a result, the transmission efficiency and reception sensitivity of the antenna have been impaired. A communicating section (constructed of a coaxial line or a microstrip line)is arranged in a portable radio communication device having a circularly polarized antenna for satellite communication, so that an appropriate distance is provided not only between a housing of the portable radio communication device and the antenna but also between a human body and the antenna.

摘要： In a mobile satellite system, a mobile communication system includes a user interface system, an antenna system, a transceiver system, a logic and signaling system. The logic and signaling system provides a communication function permitting the mobile communication system to roam between the mobile satellite system and a terrestrial based communication system responsive to the user selection of a primary service and an alternate service. The mobile communication system also includes a digital terminal equipment unit initiating setup and release for a data call, and a facsimile interface unit initiating setup and release for a facsimile call. The facsimile interface unit generates a line control packet responsive to a line state transition indicating transmission of information associated with a new line state over a communication channel. The facsimile interface unit includes a look ahead buffer to perform early line control packet detection by looking ahead a predetermined time interval into a received satellite data stream and identifying a valid idle line control packet.

摘要： An approach for selecting an asynchronous paging interval involves selecting a set of possible paging schemes for one wireless system; selecting a paging interval for another wireless system that is asynchronous with the paging schemes selected for the one wireless system; determining, after some number of paging repetitions, the probability of collision between a first paging channel in the one wireless system, and a second paging channel in the other wireless system; reselecting the paging interval for the other wireless system, asynchronous with the paging schemes selected for the one wireless system, and repeating the determining of the probability, until after some number of page repetitions, the probability reaches a prescribed minimum; and reselecting the paging interval for the other wireless system, asynchronous with the paging schemes selected for the one wireless system, and repeating the determining of the probability, until the number of paging repetitions needed to reach the prescribed minimum is reaches a selected minimum.
