摘要:
A system and method of transferring data to and from a mobile station (MS) in a cellular telecommunications network. When the MS originates a data transmission, the MS simultaneously seizes additional voice channels or control channels from the serving cell or adjacent cells, fills time slots with data packets, and asynchronously transmits the data packets over the plurality of channels in order to increase the data transfer rate. For data calls terminating at the MS, the serving mobile switching center (MSC) reserves a plurality of channels having sufficient signal strength to maintain a connection with the destination MS. The MSC informs the involved base stations that an asynchronous transmission is to be made to the MS. The MSC then assembles the data packets and starts transmission through the involved base stations to the MS over the reserved channels. The MS assembles the packets in numerical order and delevers the data to the user.

An IPTV service provider makes use of a detection that a request for content cannot be fulfilled as a result of content distribution agreements as a trigger to select a roaming partner that is able to serve the requested content. The ITF making the request is redirected to the roaming partner to allow user requests to be served. This improves user experience and provides a potential new revenue source to the service provider.

An apparatus herein coordinates streaming of multimedia content from a streaming server to a client device. While the client device is receiving a first multicast stream from the streaming server, the apparatus receives notification of the recent or impending occurrence of a defined event of interest characteristic of the multimedia content in a second multicast stream. Responsive to receiving such notification, the apparatus directs the streaming server to stream to the client device a third stream whose video content comprises windowed video content of both the first and second multicast streams. This windowed video content comprises video content from the first and second multicast streams arranged in respective windows. Such event-triggered streaming thus enables a user of the client device to simultaneously watch both the first and second streams, as desired, by efficiently receiving only a single third stream.

A system and method for automatically storing a geographic position, without requiring user interaction, makes use of the ability of a location-aware mobile device to detect its state of motion using velocity or type of movement information. A transition between motion states is used to determine a parking location of a vehicle.

In a TDMA/TDD communication system and method, communication throughput is increased by allowing direct duplex communication between the mobile stations that are within close proximity of each other. The system and method determines the range of the mobile stations from each other. Based on the range, the communication units may communicate with each other in one of either direct mode or indirect mode. If an in-range condition is determined, the mobile stations engage in direct duplex communication with each other. Otherwise, they communicate with each other in the indirect mode.

Procedures are disclosed for supporting roaming subscriber mobile station access to stored subscriber data messages. In one aspect, a received subscriber data message is routed for storage and subsequent forwarding/retrieval, not to a “home” message center, but instead to a message center either optimally positioned with respect to a current known location of the subscriber mobile station or associated with an initially receiving mobile switching center. In another aspect, a mailbox established for a given subscriber mobile station in the home message center is transferred (perhaps on a periodic basis) for storage in a local mailbox of a proximate message center within a cellular telephone network where the subscriber is currently roaming. In either case, the storing message center thereafter performs any requisite operations needed to facilitate message forwarding to or retrieval by the addressee subscriber mobile station.

A number of different mechanisms are proposed for effectuating the delivery of digital data messages to mobile stations which have currently selected an analog control channel. In one method, a signal is sent to the mobile station instructing it to make a server reselection and choose the best available digital control channel. Once the reselection is accomplished, the digital data message is delivered in a conventional manner using the digital control channel. In another method, the digital data message is reformatted for analog delivery, and the reformatted message sent over either the analog control channel or a selected analog voice channel. In yet another method, a call connection is made with the mobile station over a voice channel, and a synthesized audible message corresponding to the digital data message is transmitted over the voice channel after the subscriber answers the call. In instances where message delivery over the control channel is interrupted due to mobile station roaming, a forced re-registration occurs following the new server reselection, thus triggering continued message delivery over the new control channel.

An interface between a dual mode mobile station and a piece of data terminal equipment supports both a logical digital interface and a logical analog interface, with the analog interface passing through a modem. At set-up of either a mobile originated or mobile terminated data/fax call, a supporting dual mode communications network determines whether a digital traffic channel is available on an air interface. If so, the channel is allocated to the mobile station, and data/fax communication with the data terminal equipment occurs using the logical digital interface. Otherwise, an analog voice channel is allocated, and the data/fax communication with the data terminal equipment occurs using the logical analog interface and modem. Within the supporting network, data/fax communications via the digital traffic channel are routed through an interworking functionality that terminates a radio link protocol utilized for communicating over the digital air interface. Analog voice channel data/fax communications are instead routed through a modem pool that terminates a selected modem protocol utilized by the modem for communicating over the analog air interface.

A method of handling SMS messages in a radio telecommunications network when an originating mobile station-based Short Message Entity (MS-SME) sends a SMS origination message while operating in a first Mobile Switching Center (MSC) and then moves into a second MSC before the MS-SME receives a SMS acknowledgement message. The method begins by including a R.sub.-- Transaction ID parameter in the SMS origination message sent over the Digital Traffic Channel (DTC) from the originating MS-SME to the first MSC. If the MS-SME moved back to an anchor MSC, a SMS.sub.-- Transaction ID (SMSTID) parameter is included in an ANSI-41 SMS Delivery Backward (SMDBACK) Invoke message sent from the first MSC to the anchor MSC. The SMSTID parameter utilizes information from the R.sub.-- Transaction ID parameter to enable the MS-SME to correlate a SMS acknowledgement message with the SME origination message. If the MS-SME moved to a new serving MSC, the SMSTID parameter is placed in a SMS Delivery Point-to-Point Acknowledgement (SMDPPACK) Invoke message, and sent from the anchor MSC to the new serving MSC. The information in the SMSTID parameter is used by the second MSC to send a SMS acknowledgement message to the originating MS-SME.
摘要:
The present invention is a method within a radio telecommunications network for delivering a telephone call to a mobile station having a telephone portion, a pager portion, and a relay switch between the telephone portion and the pager portion. Data indicating that the mobile station is capable of receiving standard paging messages from a paging network is recorded in a home location register (HLR) associated with the mobile station. The method enables a subscriber to turn off the telephone portion to conserve battery power. When a call is received in a cellular network for the mobile station, and the mobile station cannot be contacted, the cellular network requests an associated paging network to send a page to the pager portion. The paging network is requested to page the pager portion of the mobile station via a datalink from the cellular network. The pager portion then activates the telephone portion through the relay switch, and the cellular network completes the call.
