Patent number: 9265025Abstract: In a GSM network, mobile stations monitor the paging channel of their respective paging group. Specifically, when a mobile station registers with the GSM network, the GSM network classifies the mobile station as belonging to one of two categories, a first category and a second category. Mobile stations belonging to the first category monitor the paging channel of their paging group at an interval defined by the GSM parameter BS-PA-MFRMS. Mobile stations belonging to the second category monitor the paging channel of their paging group at a second interval which is longer than that defined by the GSM parameter BS-PA-MFRMS.Type: GrantFiled: February 1, 2011Date of Patent: February 16, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Anders Christensson, Andreas Bergström, Paul Schliwa-Bertling
