A method for configuration of wireless network functions of a cloud radio access network, C-RAN, comprising: determining, by a first wireless network node of the C-RAN, a first policy that is used by the first wireless network node and a second wireless network node of the C-RAN to perform the configuration of the wireless network functions, wherein the first policy comprises a first part of wireless network functions that are of wireless network functions and implemented by the first wireless network node, and a second part of wireless network functions that are of the wireless network functions and implemented by the second wireless network node, wherein the second part of wireless network functions includes other wireless network functions other than the first part of wireless network functions; and sending, by the first wireless network node and to the second wireless network node, first information for configuration of functions corresponding to the second part of wireless network functions that are in the first policy and implemented by the second wireless network node, so that the second wireless network node completes configuration of functions of the second wireless network node according to the first information characterized in that the first part of wireless network functions comprises functions corresponding to a packet data convergence protocol, PDCP, layer and an upper layer of the PDCP layer, or corresponding to a radio link control, RLC, layer and an upper layer of the RLC layer, wherein the determining, by a first wireless network node, a first policy that is used by the first wireless network node and the second wireless network node to perform the configuration of the wireless network comprises: determining, by the first wireless network node according to a second policy, the first policy that is used by the first wireless network node and the second wireless network node to perform the configuration of the wireless network functions, wherein the second policy is pre-configured for the first wireless network node by an operation, administration and maintenance, OAM, device and wherein the second policy includes function configuration information corresponding to wireless network functions implemented by all wireless network nodes. determining, by a first wireless network node of the C-RAN, a first policy that is used by the first wireless network node and a second wireless network node of the C-RAN to perform the configuration of the wireless network functions, wherein the first policy comprises a first part of wireless network functions that are of wireless network functions and implemented by the first wireless network node, and a second part of wireless network functions that are of the wireless network functions and implemented by the second wireless network node, wherein the second part of wireless network functions includes other wireless network functions other than the first part of wireless network functions; and sending, by the first wireless network node and to the second wireless network node, first information for configuration of functions corresponding to the second part of wireless network functions that are in the first policy and implemented by the second wireless network node, so that the second wireless network node completes configuration of functions of the second wireless network node according to the first information characterized in that the first part of wireless network functions comprises functions corresponding to a packet data convergence protocol, PDCP, layer and an upper layer of the PDCP layer, or corresponding to a radio link control, RLC, layer and an upper layer of the RLC layer, wherein the determining, by a first wireless network node, a first policy that is used by the first wireless network node and the second wireless network node to perform the configuration of the wireless network comprises: determining, by the first wireless network node according to a second policy, the first policy that is used by the first wireless network node and the second wireless network node to perform the configuration of the wireless network functions, wherein the second policy is pre-configured for the first wireless network node by an operation, administration and maintenance, OAM, device and wherein the second policy includes function configuration information corresponding to wireless network functions implemented by all wireless network nodes. determining, by the first wireless network node according to a second policy, the first policy that is used by the first wireless network node and the second wireless network node to perform the configuration of the wireless network functions, wherein the second policy is pre-configured for the first wireless network node by an operation, administration and maintenance, OAM, device and wherein the second policy includes function configuration information corresponding to wireless network functions implemented by all wireless network nodes.
