Service processing method, pcrf, and service processing system

A policy and charging rules function (PCRF), comprising:

• a non-transitory computer readable medium having a plurality of computer readable instructions stored thereon;
• and
• a first processor coupled to the computer readable medium and configured to:
• obtain service information of a service, wherein the service information comprises a service identity,
• obtain, according to user information and the service information, information indicating that the service requires quality of service (QoS) guarantee, and service chain information,
• determine, according to the service chain information, that a network resource occupied by the service may be changed, and send the service identity and the information indicating that the service requires the QoS guarantee to a value-added service processor,
• receive target service information, from the value-added service processor, of the service corresponding to the service identity,
• generate a first control policy according to the target service information, and
• send the first control policy to a policy and charging enforcement function (PCEF) to reserve, by the PCEF, a first network resource according to the first control policy.

A service processing system, comprising:

• a value-added service processor;
• a policy and charging rules function (PCRF) configured to:
• obtain service information of a service, wherein the service information comprises a service identity,
• obtain, according to user information and the service information, information indicating that the service requires quality of service (QoS) guarantee, and service chain information,
• determine, according to the service chain information, that a network resource occupied by the service may be changed, and send the service identity and the information indicating that the service requires the QoS guarantee to the value-added service processor,
• receive target service information, from the value-added service processor, of the service corresponding to the service identity,
• generate a first control policy according to the target service information, and
• send the first control policy to a policy and charging enforcement function (PCEF) to reserve a first network resource according to the first control policy;
• and
• wherein the value-added service processor is configured to:
• receive the service identity and the information indicating that the service requires the QoS guarantee, and return the target service information of the service corresponding to the service identity to the PCRF, wherein the service identity and the information indicating that the service requires the QoS guarantee are sent by the PCRF.
