A method for sharing network resources includes: setting a sharing group based on service types in the process of setting up a bearer and determining a maximum network resource for the sharing group; and allocating a resource for the bearer in the range of the maximum network resource. The present invention also provides a system and an apparatus for sharing network resources. The embodiments of the present invention implement the sharing of a maximum transmission rate among multiple bearers in an evolved network, solve the problem of low network resource utilization caused by the fact that each bearer occupies a fixed bandwidth resource, and implement maximum utilization of network resources.
