Problems solved by technology

However, the scheme cannot avoid monitoring the GSM frame configuration which has been monitored in the previous slot division monitoring cycle
This can result in inefficiencies and wasted monitoring capacity as more slotted frames are required than are actually required

Embodiment Construction

[0027] figure 1 A reference scheme of the invention is shown. A receiving or transmitting and receiving unit R (hereinafter referred to as "monitoring unit" and marked as such in the figure), in particular a mobile or fixed equipment in a cellular communication system, can listen to a suitably determined frequency interval I R And receive (or receive and transmit) information, the frequency interval is after the time division strategy, the information is in accordance with every T FR ms repeated frame F R (see also figure 2 )organize. The frame is further divided into time slots, some of which ( figure 2 U, D) in the same system are used together with other units (such as unit R') in the frequency I R communicate on.

[0028] Unit R also obtains data from one or more transmitting (or monitored) units U1, U2...Un, e.g. belonging to different systems (indicated by vertical dashes) and at different frequencies I Ui (i=1, 2...n) work well with F R Frame F with different ...

Abstract

A receiving unit (R, R') of a monitoring communication system operating according to a first time scale uses idle Windows in its frames to search for information emitted by at least one transmitting unit (U1, U2...Un) of a monitored communication system operating according to a second time scale different from and asynchronous with respect to the first one. To efficiently cope with the need of temporarily suspending, from time to time, the monitoring for carrying out other tasks during the idle windows, the pattern of search and no-search intervals is set up so that the search intervals have a duration not exceeding a maximum time that can be devoted to the monitoring itself before starting execution of said other tasks; and the no-search interval are intervals within which the information searched for takes at least once all possible positions with respect to an idle window.

Description

technical field [0001] The present invention relates to digital communication systems, and more particularly to a method for monitoring, at a receiving unit belonging to a system operating according to a first time scale, a signal transmitted by a transmitting unit belonging to a system operating according to a first time scale A system that operates on a time scale that is different from and asynchronous to the first time scale. Background technique [0002] In a communication system, it is usually required that a unit performing a specific service obtain certain information from other units without stopping the specific service being performed. For example, in a mobile communication system, a receiving unit (a mobile device or a fixed device such as a base station) must also monitor multiple transmitting units for data transmitted by the latter according to predetermined rules: for example, a unit in a cell must periodically Neighboring cells are monitored for information...
