Abstract
The apparatus (D) is dedicated to managing momentarily radio link interruptions between mobile stations (MS-i) and at least one radio network controller (BSC) of a radio access network (RAN) of a communications network. The apparatus comprises firstly detector means (DM) capable of detecting a radio link interruption between a mobile station (MS-i) and a radio network controller (BSCn), and secondly control means (CM) capable, on an interruption being detected by the detector means (DM), of ordering the radio network controller (BSCn) to suspend the radio link and then to attempt reactivate the radio link in application of a selected timetable.
Claims13
A method of managing radio links between at least one mobile station and a radio access network of a communications network, the method comprising:
- detecting whether a radio link interruption occurs which prevents said mobile station and said radio network controller from communicating with each other via a radio link;
- in the event of an interruption being detected in the radio link between said mobile station and said radio access network, suspending said radio link and attempting to reactivate said radio link for a predetermined time interval;
- and
- if said radio link is not reactivated within the predetermined time interval, determining that said interruption is permanent.
An apparatus for managing radio links between at least one mobile station and a radio network controller of a radio access network of a communications network, the apparatus comprising:
- detector means arranged to detect a radio link interruption which prevents said mobile station and said radio network controller from communicating with each other via a radio link;
- and
- control means arranged, in the event of said interruption being detected, to order said radio network controller to suspend said radio link, and then to attempt to reactivate said radio link for a predetermined time interval, and determine that said interruption is permanent if said radio link is not reactivated within said predetermined time interval.
A radio network controller of a radio access network of a communications network, the controller comprising an apparatus for managing radio links between at least one mobile station and the radio network controller, the apparatus comprising detector means arranged to detect a radio link interruption which prevents a mobile station and said radio network controller from communicating with each other via a radio link, and control means arranged, in the event of said interruption being detected, to order said radio network controller to suspend said radio link, and then to attempt to reactivate said radio link for a predetermined time interval, and determine that said interruption is permanent if said radio link is not reactivated within said predetermined time interval.
Equipment for a radio access network of a communications network including at least one radio network controller, the equipment comprising an apparatus for managing radio links between at least one mobile station and the radio network controller, the apparatus comprising detector means arranged to detect a radio link interruption which prevents a mobile station and said radio network controller from communicating with each other via a radio link, and control means arranged, in the event of said interruption being detected, to order said radio network controller to suspend said radio link, and then to attempt to reactivate said radio link for a predetermined time interval, and determine that said interruption is permanent if said radio link is not reactivated within said predetermined time interval.
A communications network comprising a radio access network (RAN) including at least one radio network controller (BSCn), and at least one apparatus for managing radio links between at least one mobile station and the radio network controller, the apparatus comprising detector means arranged to detect a radio link interruption which prevents a mobile station and said radio network controller from communicating with each other via a radio link, and control means arranged, in the event of said interruption being detected, to order said radio network controller to suspend said radio link, and then to attempt to reactivate said radio link for a predetermined time interval, and determine that said interruption is permanent if said radio link is not reactivated within said predetermined time interval.
