Method and Apparatus for Processing Bearer

A method for processing a bearer, the method comprising:

• according to a preset layer-7 protocol type matching rule, performing depth packet inspection DPI processing on a traffic flow of a service, so as to obtain a DPI processing result;
• according to the DPI result and the preset matching rule, determining a service quality attribute parameter of the service;
• and
• reporting the service quality attribute parameter of the service to a PCRF through an Rx interface, so that the PCRF creates a dedicated bearer of the service according to the service quality attribute parameter of the service;
• or
• according to a preset layer-3 or layer-4 protocol type matching rule, performing shallow packet inspection SPI processing on a traffic flow of a service, so as to obtain an SPI processing result;
• according to the SPI result and the preset matching rule, determining a service quality attribute parameter of the service;
• and
• reporting the service quality attribute parameter of the service to a PCRF through an Rx interface, so that the PCRF creates a dedicated bearer of the service according to the service quality attribute parameter of the service.

An apparatus for processing a bearer, comprising:

• a processing module configured to:
• perform depth packet inspection DPI processing on a traffic flow of a service according to a preset layer-7 protocol type matching rule so as to obtain a DPI processing result, or
• perform shallow packet inspection SPI processing on a traffic flow of a service according to a preset layer-3 or layer-4 protocol type matching rule so as to obtain an SPI processing result;
• a service quality attribute parameter determining module configured to determine a service quality attribute parameter of the service according to the DPI result and the preset matching rule, or according to the SPI result and the preset matching rule;
• and
• a dedicated bearer creating module configured to determine whether the service quality attribute parameter is the same as a service quality attribute parameter of an existing bearer, and if different, create a dedicated bearer for the service.
