Patent ID: 8457051

Claim:
A method for differentiating operators in a network, comprising: receiving information about a frequency occupied by an air interface resource of a service; and querying corresponding operator information from configured mapping relation between frequency information and operator information according to the received information about the frequency occupied by the air interface resource of the service; wherein the mapping relation between the frequency information and the operator information is configured at a mobile switching center (MSC), and the querying of the corresponding operator information comprises: querying, by the MSC, the corresponding operator information from the configured mapping relation between the frequency information and the operator information according to information about a frequency occupied by an air interface resource of a circuit switched (CS) voice service from a base station controller (BSC)/packet control function (PCF); or wherein the mapping relation between the frequency information and the operator information is configured at a packet data serving node (PDSN), and the querying of the corresponding operator information comprises: querying, by the PDSN, the corresponding operator information from the configured mapping relation between the frequency information and the operator information according to information about a frequency occupied by an air interface resource of a packet switched (PS) data service from a base station controller (BSC)/packet control function (PCF).
