Single-Card Dual-Standby Terminal and Data Service Connecting Method

摘要

The present invention relates to processing that a single-card dual-standby terminal establishes a packet switch (PS) connection. In embodiments of the present invention, a single-card dual-standby terminal initiates a data service connection request through a currently used access network, and a packet switch core network performs processing on the data service connection request of the terminal according to a network resource and a data service requested by the terminal, so that a PS connection bearer of the single-card dual-standby terminal is established on a proper network, thereby fully utilizing an existing network resource and reducing electric energy consumption of a single-card dual-standby terminal.
