Method and arrangement in a telecommunication system

摘要

A method (200) for use in a GSM network (11), comprising monitoring (205) by mobile stations (18) in the GSM network (11) of the paging channel of their paging group. When a mobile station (18) registers (210) with the GSM network (11), the GSM network classifies (215) the mobile station as belonging to one of two categories, the two categories being such that one of the two categories monitors (225) the paging channel of its paging group at an interval defined by the GSM parameter BS-PA-MFRMS and the other category monitors (230) the paging channel of its paging group at a second interval which is longer than that defined by the GSM parameter BS-PA- MFRMS.
