Abstract:
1. A method for paging a terminal device across heterogeneous networks, comprising: selecting, by a current network, another network to execute a paging procedure, when the current network, upon receipt of user data, determines that a communication interface of the terminal device in the current network is in a Dormant Mode, wherein the another network uses different wireless standards from the current network; sending, by the another network, a paging message to the terminal device to enable the terminal device to reconnect to the current network, sending, by a network where the terminal device is located, a request message to another network selected by the network, to instruct the terminal device to enter the Dormant Mode, wherein the another network uses different wireless standards from the network where the terminal device is located; and initiating, by the another network having received the request message of entering Dormant Mode, a procedure for enabling the corresponding communication interface of the terminal device to enter the Dormant Mode.
