Abstract:
1. A method for transmitting Packet Switch (PS) domain service data, being applied in the service data transmission process between a service application side and a protocol side through serial port, and comprising: establishing a correlation between multiple services and a predetermined transmission channel, wherein the predetermined transmission channel comprises multiple links and multiple channels between a Point-to-Point Protocol (PPP) client and a PPP server; and according to the correlation, transmitting the service data of the multiple services between the service application side and the protocol side via the predetermined transmission channel: wherein the multiple links comprise multiple Packet Data Protocol (PDP) links and multiple PPP links, and the correlation comprises: a first correlation, used to indicate a correlation between PDP link identifiers (IDs) of the multiple PDP links and channel identifiers (IDs) of the multiple channels; a second correlation, used to indicate a correlation between the PDP link ID and port numbers of the multiple services; and a third correlation, used to indicate a correlation between the channel ID and the PPP link identifiers (IDs) of the multiple PPP links; wherein the step of transmitting the service data of the multiple services between the service application side and the protocol side via the predetermined transmission channel according to the correlation comprises: transmitting the service data of the multiple services between the service application side and the PPP client; transmitting the service data of the multiple services between the PPP client and the PPP server according to the first correlation, the second correlation and the third correlation; and transmitting the service data of the multiple services between the PPP server and the protocol side according to the first correlation and the third correlation.
