COMMUNICATION SYSTEM |
摘要 |
When a representative service control device receives a PDP context succession request signal according to a handover communication procedure prescribed in an applicable standard, the representative service control device transmits a P-TMSI contained in the PDP context succession request signal as an address request to a database device. When the representative service control device receives address information of a service control device from the database device, the representative service control device forwards the PDP context succession request signal received from the request transmission means to the received address. |
