Abstract:
1. An interworking method comprising: establishing a first wireless data path following a first wireless communication protocol between an interworking device and a first network; establishing a plurality of second wireless data paths between the interworking device and a plurality of terminal devices, wherein the plurality of second wireless data paths respectively correspond to the plurality of terminal devices and follow a second wireless communication protocol; establishing a plurality of first network links between the interworking device and the first network through the first wireless data path, wherein the plurality of first network links respectively correspond to the plurality of terminal devices; storing mapping information for the plurality of first network links that corresponds to relationships between the plurality of terminal devices and the plurality of first network links; receiving a message from a first terminal device of the plurality of terminal devices through one of the plurality of second wireless data paths; and transmitting to the first network the message received from the first terminal device through a corresponding one of the plurality of first network links corresponding to the first terminal device based on the stored mapping information, wherein the first wireless communication protocol supports a handover operation, and the second wireless communication protocol does not support a handover operation.
