The present invention provides a method and an apparatus for processing a bearer. The method includes: according to a preset layer-7 protocol type matching rule, performing depth packet inspection DPI processing on a traffic flow of a 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 a DPI/SPI processing result; according to the DPI/SPI result and the preset matching rule, determining a service quality attribute parameter of the service; and determining whether the quality attribute parameter is the same as a quality attribute parameter of an existing bearer, and if different, creating a dedicated bearer for the service. The apparatus includes: a processing module, a service quality attribute parameter determining module, and a dedicated bearer creating module, so as to implement that a dedicated bearer of a corresponding service is created by a PDN GW only through performing depth packet inspection DPI/SPI processing on the traffic flow of the service without the need of creating a dedicated bearer through a PCRF, which increases diversity of a dedicated bearer creating apparatus.
