Abstract
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.
Claims10
A data service connection establishing method for a single-card dual-standby terminal, comprising:
- initiating a data service connection request through a first network;
- receiving a response to the data service connection request through the first network;
- establishing a data service connection bearer on the first network when the response to the data service connection request indicates that a data service bearing capability of a general packet radio service (GPRS) of the first network can bear the data service connection request;
- enabling a radio frequency of a second network on the single-card dual-standby terminal when the response to the data service connection request indicates that the data service bearing capability of the GPRS of the first network cannot bear the data service connection request;
- establishing the data service connection bearer on the second network when the response to the data service connection request indicates that the data service bearing capability of the GPRS of the first network cannot bear the data service connection request;
- and
- switching the data service connection bearer from the second network back to the first network when a message is received indicating that the data service bearing capability of the GPRS of the first network can bear the data service connection request.
