  • the present invention relates to a distributed service management system and method to support the fast deployment of personal communication services. Specifically, the present invention enables a nomadic user to subscribe to, activate, and use personal communication services anywhere and at any time without interoperability problems among different personal communication service providers and phone companies.
  • One important goal of personal communication services is to allow users to communicate from anywhere to anywhere at any time.
  • Such personal communication services generally involve multiple service providers including local and long distance telephone companies and cellular telephone companies.
  • An example of a personal communication service is as follows:
  • a personal communication service provider e.g., a cellular telephone company
  • a rental phone company e.g., from an airline or car rental company
  • a sales representative travels from a home location e.g., New Jersey, to a visiting location, e.g., California. In order to get in touch with his/her boss and his/her home, the user rents a wireless portable phone immediately upon arrival in
  • the user Using the rental phone, the user is provided with basic mobile phone service from the personal communication service provider.
  • the user would like the following features:
  • This kind of personal communication service involves a plurality of service providers. There are (a) the local telephone company at the home location, (b) a long distance telephone company, (c) the local telephone company at the visiting location, and (d) the personal communication service provider (i.e. the cellular telephone company) at the visiting location. All of these are referred to herein as "service providers" .
  • interoperability problems among the different service providers must be resolved.
  • the interoperability problems can be divided into two categories: (a) location tracking and (b) service management.
  • the interoperability problem for location tracking has been addressed by adopting signaling protocols used by the mobile phone industry.
  • Location tracking functions are implemented using two location registers.
  • One of the registers, maintained by the local telephone company of the user's home location, is called the Home Location Register (HLR) .
  • the other register, maintained by the local telephone company of the visiting location, is called the Visiting Location Register (VLR) .
  • the HLR stores the customer profile data and the location of the VLR of the user.
  • the customer profile data contains important information such as the user name/address, preferred long distance carrier, service features (e.g., call forwarding and call restriction), billing, and other administrative related information.
  • a new VLR is created in the new location.
  • a part of the profile data is loaded into the VLR such that the service provider at the visiting location can implement service features (e.g. call restriction) for the visiting user.
  • the location of VLR in the HLR is changed to the new VLR location, and the VLR in the previously visited location is deleted.
  • the process of creating a new VLR, loading profile data to the VLR, and updating the visiting location of a user in the HLR is called "automatic roamer registration" .
  • the interoperability problem for service management is much more complex than that for location tracking.
  • Service management refers to a collection of functions required to enable a personal communication service user to subscribe to, modify, and activate service features anywhere and at any time.
  • Examples of service management functions include phone number administration, customer profile data management, service activation, and security administration.
  • the phone number administration function is important for maintaining the uniqueness of phone numbers.
  • the customer profile data management function provides customer profile databases and user interfaces for creating, modifying or transferring such databases.
  • the service activation function extracts part of the data specifying service features from the profile data and loads this data into physical communication systems that process calls.
  • the service activation function also controls the activation and deactivation of the service features.
  • the security administration function prevents or detects unauthorized uses of services and service management functions.
  • Service management functions of this type need to be implemented to provide personal communication services involving multiple service providers.
  • Such implementation of the service management functions generally requires interactions between application software and various databases owned and operated by the different service providers.
  • An example of such a service is call forwarding to a temporarily rented portable phone.
  • the application may, for example, need to perform the following database access operations at databases maintained by various different service providers: check credit databases owned by credit card companies or phone companies to determine whether the user is able to pay for the service; check the customer profile database in the user's HLR to determine whether the user is currently located in a place other than the visiting location currently stored in the HLR; check the credit and network databases of long distance phone companies specified by the user to determine whether the user can use a particular long distance carrier in the visiting location,- load profile data into the VLR at the visiting location and update the HLR with the location of the VLR if necessary; and ⁇ load the profile data to the call processing systems and activate the service.

The VLR will be transmitted to a service control point 420 or central office 402 that performs call restriction and routing at the visiting local telephone network.
  • the long distance carrier service management system 310 determines whether it has coverage at the visiting location and also performs a credit check using the credit records maintained in its database. If both the area of coverage and credit check are positive, the insertion request is granted. 5.
  • the home local telephone company through its service management system 210, will check the customer credit record, create an HLR containing the call forwarding information and VRL location, and down load the HLR to a local service control point (e.g. service control point 220) or central office (e.g. the central office 202) covering the base telephone 203.
  • a local service control point e.g. service control point 220
  • central office e.g. the central office 202
  • the call forwarding service is activated by causing the central office 202 to route calls originally directed to the base telephone 203 through the networks 200, 300, and 400 to the mobile phone 506. There are several techniques by which the calls can be forwarded through the networks 200, 300 and 400 and these are discussed below.

  • the local coordinator agent at service management system 510 also arranges for participant agents at the other service management systems 410, 310, 210 to delete this customer profile record.
  • the home local telephone company deactivates the call forwarding service and deletes the HLR from the service control point or central office which controls the call forwarding.
  • the service management system 410 will delete the VLR for this user.
  • the call forwarding operation can be carried out in a number ys described below:
  • a call originally directed to the user's base phone can be forwarded to a unique number assigned to the user's portable phone by the personal communication service provider.
  • a call originally directed to a user's base phone can be forwarded to a group number assigned to the personal communication service provider.
  • the personal communication service provider maintains a database in a storage device which links a base number provided by the user (e.g. the user's home number or office number or any other base number provided by the user) to the telephone number assigned to the rental portable phone.
  • the base phone number serves as a key to retrieve the rental phone number. After retrieving the rental phone number, the incoming call is routed to the user.
  • This method is the same as the previous method but there is a single nationwide group number.
  • the call is forwarded from the user's base phone to the nationwide group number.
  • the call is forwarded to the appropriate service provider or telephone having the retrieved entry. If the call is routed to the group number of a specific service provider, another table is indexed to obtain the telephone number of the phone to which the call is to be forwarded.
  • All of these forwarding procedures can be implemented using the distributed service management system of the present invention by inserting the appropriate call forwarding information into the databases of the appropriate service providers .
  • the provision of a personalized communication service to a user comprises a plurality of database operations including, insertion, record checking and deletion operations. These are carried out across multiple databases of multiple service providers using the distributed service management system and method of the present invention. It should be noted that some trigger rules may be created to implement a service such as call forwarding to a temporary user of a portable phone. For example, to carry out step 5 by the service management system of the home local company, a trigger rule represented by the following pseudocode may be used.

Abstract

Un système réparti de gestion de services permettant de fournir des services de communications comprend une pluralité de systèmes de gestion de services individuels (210, 310, 410, 510) offerts par une pluralité de fournisseurs de services. Chaque système de gestion de services comporte sa propre base de données locale (214, 314, 414, 514) et une interface moniteur interactif de transactions réparties (IDTM) dans un ordinateur (212, 312, 412, 512), qui permet aux applications à fonctionnement local d'accéder à la base de données locale, ainsi qu'aux bases de données à distance appartenant à des systèmes de gestions de services à distance. Les interfaces permettent d'intégrer de multiples systèmes de gestion de services individuels dans un seul système de gestion de transactions à plusieurs bases de données. Le système réparti de gestion de services peut être utilisé pour fournir des services de communications personnelles spéciaux impliquant de multiples fournisseurs de services, tels qu'un transfert d'appels vers un téléphone mobile loué temporairement.
