Definitions

  • the present invention belongs to the field of communications, and in particular, to a call processing method and system. Background of the invention
  • number portability allows users to continue to use the original number without changing the number when the address is relocated, replaced with a service provider, or replaced. Therefore, it is very popular with users.
  • the basic point of implementation of the number portability service is that when the user who owns the number portability service is called, the called number will not change due to the change of the geographical location or the change of the operator, and the user will call the called party as the calling party.
  • the calling number displayed is also the original number of the user.
  • the number portability service can be implemented in the network or implemented in the network.
  • the implementation in the network is basically limited to the local network, and it is difficult to handle the situation of user roaming.
  • Inter-network implementation is generally implemented by call forwarding or database query. Call forwarding can only be carried by the number of the voice. The user can apply for a call transfer service from the old number to the new number, but cannot receive text and multimedia information sent to the old number.
  • the database query method is adopted, the data may be a centralized database or a distributed database, and the centralized database stores all the carried numbers in a dedicated database; the distributed database means that each operator has its own database. Responsible for maintaining their number.
  • the centralized database is conducive to management, and it is not easy to see the situation where the operator's responsibility is unclear, but the construction cost is high and the construction is difficult. Due to the maintenance of various operators, the distributed database is relatively difficult to construct, but there is a phenomenon that the responsibility is unclear, which is not conducive to the implementation of the number portability service.
  • the database query method to achieve the number When the code carries the service, it also needs to adopt the route selection technology of all call inquiry (ACQ) mode, which has relatively large changes to the existing network, and involves complex account opening and billing processing, which is complicated to implement and at the same time, does not consider the short message service. Implementation. Summary of the invention
