Means for transferring a call number or the radio call code and associated message information to the control station. The other communication network is based on CCITT Recommendation X.264. An e-mail network having an interface function of 400 is desirable.

Here, a feature of the present invention is that the radio paging network has means for receiving an inter-network connection request coming from another communication network and connecting this communication network to the radio paging network. The connecting means includes means for searching for information of a control station in which a corresponding receiver is registered in advance according to the public telephone network shared radio call number or the radio call code coming from the another communication network. And means for transferring the radio call number shared by the public telephone network or the radio call code and associated message information to the control station according to the search result of the search means. The other communication network is based on CCITT Recommendation X.264. An e-mail network having an interface function of 400 is desirable.

[0011]

When a paging receiver is called from a data terminal connected to an e-mail network, a communication network identifier is sent to the paging network as an inter-network connection request from the data terminal connected to the e-mail network. Send out. In this communication network identifier, information of the communication network of the transmission source of this identifier and information of the communication network of the destination are written and transferred to the communication network of the destination. The communication network receiving this establishes a communication path with the communication network of the transmission source of the communication network identifier. In order to execute this opening procedure, a gateway device is provided here.

When the communication networks are connected, a radio call code of a radio call receiver to be called is input from the data terminal device. The e-mail network sends this paging code to the paging network. The paging code reaches the paging network and is input to the gateway device. In this gateway device, a control station in a radio paging network corresponding to the radio paging code registered in advance is searched with reference to a database in accordance with the radio paging code.

The paging code is transferred to the control station of the paging network together with the paging request and the message information of the paging receiver. In the control station, the user of the radio paging receiver having the radio paging code retrieves a desired call area registered in advance with reference to the database and transmits a paging signal.

Thus, the radio selective calling system by the electronic mail network and the radio selective calling system by the telephone network are mutually connected, and the service provided by the radio selective calling system by the telephone network is selectively transmitted by the radio network. It can also be used in systems.
