Title: Method for allocating resources during high speed data transmission in a wireless telecommunications system
Inventor: MARKS ROBERT JERROLD
IPC: H04L12/56
Filed: 1999-08-19
Abstract: A wireless telecommunications system includes a selection distribution unit (SDU) for receiving high speed data. The high speed data is stored in a buffer queue within the SDU prior to allocation of high speed data resources by a base station controller. Signaling between the base station controller and the SDU ensures that high speed data resources are not prematurely released. More particularly, constant monitoring of high speed data levels within the buffer queue triggers specific signaling from the SDU to the base station controller to guide the allocation of high speed data resources.

Patent CA-2283971-A1 (CA)
Title: Digital audio broadcast system with local information
Inventor: WARWICK COLIN ALAN
IPC: H04J11/00
Filed: 1999-09-27
Abstract: A digital audio broadcast channel is used in accordance with the principles of the present invention to broadcast local content information signals included with an associated geographically identifying code (e.g., a zip code) for reception only by those receivers associated with the geographically identifying code. Preferably, local content broadcasts containing audible information are preferably compressed for transmission to increase the capacity of the channel. A disclosed receiver monitors received signals for active local broadcasting relating to that particular locality, and switches to the reception of that local content information signal instead of the normal mode of reception of a general broadcast information signal for the duration of the local content information signal. Preferably, the unique local broadcast identifier code is contained in a header of the transmitted data packets. General broadcast content information and local content information can be received substantially simultaneously such that the audio signals relating to the general broadcast content and the local content are superimposed on one another, or reception of the local information may preempt reception of general broadcast information.

Title: Background software loading in cellular telecommunication systems
Inventor: GENELL BROR ERIK GUNNAR
IPC: G06F13/00
Filed: 1998-05-15
Abstract: A method of loading software in cellular telecommunication systems is disclosed. The method permits software data to be loaded in the background while transceiver devices may be engaged in voice or data traffic. Each of the devices includes a run-time memory, backup memory, and a device processor. The data is transmitted from the mobile switching center to the backup memory of the designated device while the device is operating from run-time memory. In a first embodiment, the data is copied from backup memory to run-time memory when the device is idle. In a second embodiment, device operations are switched to run from backup memory when the device is idle. Subsequent software loadings cycle between run-time and backup memories. In a third embodiment, a single memory bank comprises both run-time and backup memory.  The backup memory area is located in a different location in the memory bank than the run-time memory area. The software data is written in the background to the backup memory area without disturbing device traffic. When the device is idle, the location pointer is switched to the backup memory area so that the device runs newly loaded software. The inventive concept permits efficient software loading that reduces down-time and is transparent to the user.
