Abstract
The invention relates to a GSM-type telecommunications system having a superordinate unit or Home Location Register (HLR) which includes software necessary for base functions and relevant supplementary services. The software in the superordinate unit (HLR) is structured such to provide a first software set-up (21) for requisite base functions, a second software set-up (22) for added supplementary services, and a third software set-up (23) for coordinating the first and second software set-ups, so that the third software set-up (23) can be adapted to enable a supplementary service-related portion (22a) of the second software set-up (22) to be included or removed without affecting the first software set-up.
Claims21
A GSM-type telecommunications system adapted for mobile subscribers in which the level of services can be increased or reduced by one or more supplementary services, wherein in addition to said mobile subscribers (MS), the GSM system comprises:
- one or more base station systems (BSS) for managing the radio resources needed for setting-up and releasing connections to and from mobile subscribers located in an area covered by respective base station systems, and
- one or more local mobile services switching centers (MSC/VLR) connected to one or more superordinate units (HLR),
- wherein said one or more superordinate units (HLR) include software for providing base functions and relevant supplementary services, and
- wherein the software in a superordinate unit (HLR) is structured to provide
- a first software set-up (21) for providing the necessary base functions;
- a second software set-up (22) for adding supplementary services, and
- a third software set-up (23) for coordinating the first and the second software set-ups and for enabling a part (22a) of said second software set-up (22) belonging to a supplementary service to be added or removed without affecting the first software set-up.
