Abstract: A method is provided for a simultaneous call service of a dual mode mobile terminal that simultaneously supports a CDMA 2000 1x Release A and a EVDO system. A dual mode mobile terminal may set a voice call that is additionally requested regardless of a service system for a data call, which is being provided for service, by a call setting procedure of a simultaneous call service provided by the CDMA 2000 1x Release A system. In addition, if the voice call is released while the voice call and a data call are being simultaneously provided for service from the CDMA 2000 1x Release A system, the dual mode mobile terminal may reselect a service system for the data call to a system having a wider bandwidth.

Abstract: A system and method for managing the communication of information in a mobile network allocates a currently unoccupied, reserve paging channel as a dedicated channel for receiving short message information in a mobile terminal. The method includes determining whether information to be transmitted to the mobile terminal includes short message information or paging information. If the received information includes short message information, a base station transmits reference information to the mobile terminal over a paging channel. The reference information then instructs the mobile terminal to receive the short message over the reserve channel. If the received information includes short message information and paging information, the mobile terminal receives the short message over the reserve channel and then receives the paging information over the paging channel. By receiving short messages over a channel other than the paging channel, load on the paging channel is substantially reduced.
