• HLR location home register

• the user's authority data and new service data are stored in the end office switch, and the end office directly accesses the database of the office to obtain the corresponding information and complete the related call processing functions. Therefore, the user number must be bound to the end office, that is, the data is bound to the end office, and users cannot roam on the local network and cross-office migration.
• the services are provided by the end office, and there are many types of end office models. The service provision capabilities of each end office model are different, so it is difficult to provide or promote unified services across the entire network in the existing fixed communication network; and the data storage method in the fixed communication network also brings intelligent services at the end Bureau difficult to trigger issues.
• HLR unified location attribution register

• the HLR interacts to obtain the user's location information and new service information, and completes the user's basic calling functions.
• MAP protocol is a mobile communication network protocol. None of the fixed network switches support the above protocols, so it cannot be applied to fixed communication networks.
• the intelligent service without the access code is triggered by the end office.
• the calling intelligent service needs to be triggered by the calling end office.
• the intelligent service on the calling side such as a fixed prepaid service, is triggered by the calling end office inserting an access code before the called number and sending it to the SSP.
