If a user on another network calls a user on the operator's internal GSM network, and the user has roamed to the operator's CDMA network, it needs to go through paths 2 and 3 from the other network to the integrated gateway office, and from the integrated gateway office to the CDMA network.

First, through path 1, the user on another network initiates a call to the GSM network user of the operator, and the call is routed to the integrated gateway office of the operator through the other gateway office, and then through path 3, the integrated gateway office judges that the called user is The GSM network user sets up the call on the service module (G_SPC module) responsible for handling GSM services. When the G_SPC module gets the roaming number, it finds that the GSM user has roamed to the CDMA network. Therefore, the call is moved to the responsible CDMA network through the internal interface.
