Abstract:
A telecommunications system for managing congestion within a home location register within a cellular network, said telecommunication system comprising:a central processor within said home location register, said central processor having a current load associated therewith; at least one mobile switching center physically separate from and in communication with said home location register, said at least one mobile switching center being capable of receiving registration requests from mobile stations in wireless communication with said at least one mobile switching center and transmitting at least one registration message associated with each of said registration requests to said home location register; wherein said home location register periodically transmits said current toad to said at least one mobile switching center; at least one threshold associated with said at least one mobile switching center, said current load being compared with said at least one threshold; a reduction algorithm associated with said at least one mobile switching center, said reduction algorithm being capable of determining a reduction amount when said current load exceeds said at least one threshold; and an access restriction algorithm associated with said at least one mobile switching center, said access restriction algorithm being capable of receiving said reduction amount and reducing the number of said at least one registration message transmitted from said mobile switching center to said home location register by at least said reduction amount.
