A service configuration method, comprising: sending, by a core network device, first configuration information to an access network device, the first configuration information being used to indicate one Quality of Service, QoS, resource type in a plurality of QoS resource types to be selected, and the one QoS resource type indicated by the first configuration information being used for the access network device to transmit a first service; and the plurality of QoS resource types comprising a Guaranteed Bit Rate, GBR, type, a Non-Guaranteed Bit Rate, Non-GBR, type and a delay critical Guaranteed Bit Rate, GBR, type; characterized in that, the method further comprises: receiving, by the core network device, feedback information sent by the access network device, the feedback information being used to indicate that the access network device does not support the one QoS resource type; and sending, by the core network device, second configuration information to the access network device according to the feedback information, the second configuration information being used to indicate other QoS resource types in the plurality of QoS resource types except the one QoS resource type, and said other QoS resource types indicated by the second configuration information being used for the access network device to transmit the first service; wherein the feedback information is further used to indicate at least one QoS resource type in the plurality of QoS resource types that is supported by the access network device; and said other QoS resource types belong to the QoS resource type in the at least one QoS resource type. sending, by a core network device, first configuration information to an access network device, the first configuration information being used to indicate one Quality of Service, QoS, resource type in a plurality of QoS resource types to be selected, and the one QoS resource type indicated by the first configuration information being used for the access network device to transmit a first service; and the plurality of QoS resource types comprising a Guaranteed Bit Rate, GBR, type, a Non-Guaranteed Bit Rate, Non-GBR, type and a delay critical Guaranteed Bit Rate, GBR, type; characterized in that, the method further comprises: receiving, by the core network device, feedback information sent by the access network device, the feedback information being used to indicate that the access network device does not support the one QoS resource type; and sending, by the core network device, second configuration information to the access network device according to the feedback information, the second configuration information being used to indicate other QoS resource types in the plurality of QoS resource types except the one QoS resource type, and said other QoS resource types indicated by the second configuration information being used for the access network device to transmit the first service; wherein the feedback information is further used to indicate at least one QoS resource type in the plurality of QoS resource types that is supported by the access network device; and said other QoS resource types belong to the QoS resource type in the at least one QoS resource type. receiving, by the core network device, feedback information sent by the access network device, the feedback information being used to indicate that the access network device does not support the one QoS resource type; and sending, by the core network device, second configuration information to the access network device according to the feedback information, the second configuration information being used to indicate other QoS resource types in the plurality of QoS resource types except the one QoS resource type, and said other QoS resource types indicated by the second configuration information being used for the access network device to transmit the first service; wherein the feedback information is further used to indicate at least one QoS resource type in the plurality of QoS resource types that is supported by the access network device; and said other QoS resource types belong to the QoS resource type in the at least one QoS resource type.
