A multimode network management configuration model upgrade method and apparatus are disclosed. The method includes: expanding a configuration directory of all systems supported by a serving end and a client; conducting secondary development and deployment of a configuration model in the configuration directory; and issuing a configuration to a base station side. By expanding the configuration directory of all systems supported by the serving end and the client, unified management of all systems supported by the serving end and the client is completed, so that the secondary development and deployment of the configuration model conducted in the configuration directory is more convenient and effective. By means of the above method, each product developer can complete automatic upgrading of a multimode configuration model with respect to service constraints of his/her products, thereby reducing the communication cost, and increasing the research and development quality, so that repeated development caused by the same platform service can be avoided.
