Abstract:
A telecommunications system comprises a source base station (BSS), a destination base station (BSD) having a synchronization searcher (S), and a synchronization start position determination unit (101) which establishes a start position (SP) of a synchronization search window for the synchronization searcher of the destination station. The synchronization search window detects, for synchronization purposes, a transmission of the specified mobile station received at the destination base station during a handover of a connection involving the specified mobile station from the source station to the destination base station. In accordance with an aspect of the present invention, the synchronization start position determination unit establishes the start position of the synchronization search window with reference to a calculated distance of the mobile station from the destination base station.
Abstract:
A telecommunications system (18) capitalizes employment of a system frame number (SFN) for synchronizing plural real time clocks (206) provided at one or more nodes of the network. System frame signals (e.g., pulses) are distributed from a source (210, 310) to processors (202) having slave clocks (206S) that need to be synchronized with a master clock. A master processor (202M, 302T) sends a clock set message (500) to the processors, the clock set message including a reference master clock time (506) and a reference system frame number (504). The recipient processors which receive the clock set message resynchronize their respective slave clocks using the reference master clock time and the reference system frame number. In one mode, the clock set message directs the recipient processors to set their respective slave clocks to the reference master clock time upon the recipient processors obtaining the reference system frame number. In another mode, the clock set message advises the recipient processors of an actual master clock time at the reference system frame number, thereby enabling the recipient processor to calculate an adjusted slave clock time.
Abstract:
In a mobile radio communications system, first radio resources are allocated to a first mobile radio communication. The term "radio resources" relates to one or more resources used to support a mobile radio communication and may include, for example, radio bandwidth, transmit power, signal and data processing hardware and software resources, radio transceiving resources, etc. A second group of radio resources is allocated to a second mobile radio communication. When a block of user information needs to be transmitted that requires an additional amount of radio resources, the first and second mobile radio communications are interrupted or their service levels are reduced for a brief time period. At least part of the block of information is transmitted during that time period using at least some of the first and second radio resources allocated for the first and second mobile radio communications. After that time period, transmission of the first and second mobile radio communications is resumed at full (or partial) service levels.
Abstract:
Un método de transmitir datos entre una base station (BS -Estación de Base) y un número de usuarios conectados a la estación de base, caracterizado por, cuando se recibe una solicitud (104) de enviar un bloque de datos grande desde uno de los usuarios, imponer interrupciones alternantes (118) sobre los otros usuarios, y transmitir el bloque de datos grande durante las interrupciones.
