相互接続契約判定システム、相互接続契約判定装置、及び、相互接続契約判定方法
Document Type and Number:
Japanese Patent JP4056971
Kind Code:
B2
Abstract:
There are provided an interconnection agreement determining system, apparatus, and method capable of accurately determining whether the carrierto which an originating communication terminal subscribes and the carrierto which a receiving communication terminal subscribes have a short message interconnection agreement with each other, even if the receiving communication terminal uses number portability. When a location-area MSC 20 receives an SMS originating signal, an interrogating unit 21 sends an SRIforSM signal including the MSISDN of a receiving terminal 10b to an HLR 30. When the location-area MSC 20 receives an SRIforSMack signal from the HLR 30, a subscriber-identification-information obtaining unit 22 obtains an IMUI contained in the SRIforSMack. An on-origination carrier identifying unit 23 identifies from the IMUI the carrierto which the receiving terminal 10b subscribes. The location-area MSC 20 determines whether the carriers have an SMS interconnection agreement with each other, on the basis of identification made by an on-origination carrier identifying unit 23.
