摘要:
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 carrier to 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.

There are provided an interconnection agreement determining system, apparatus, and method capable of accurately determining whether the carrier to which an originating communication terminal subscribes and the carrier to 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 carrier to 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.
摘要:
The unnecessarily increase of the information amount of subscriber information retained by a local subscriber information management device is prevented even if the number of subscribers increases, so that the limit of the number of subscribers is extended to support the increasing number of subscribers without increasing the capacity of subscriber information retaining means in the local station (local subscriber information management device). Based on information contained in subscriber management information 211, 221 including information representing each mobile terminal 310, 320 acquired by local stations 210, 220 of a mobile communication system 100 and subscriber information corresponding to each mobile terminal 310, 320, the relevant subscriber management information 211, 221 are selected and processed to be prevented from being retained after call control is performed according to the acquired subscriber management information.
