A method for planning capacity of a wireless broadband network, comprising: in a network constructed according to a network planning parameter, performing access scheduling on a User Equipment UE in accordance with a type of a service of the UE; acquiring statistics on an indicator of performing access scheduling on the UE; and determining whether the indicator meets a requirement in network capacity planning; and when the indicator meets the requirement, determining a target planning parameter as the network planning parameter; otherwise when the indicator does not meet the requirement, adjusting the network planning parameter until the indicator meets the requirement in network capacity planning, wherein the performing access scheduling on a UE in accordance with a type of a service of the UE comprises: simulating a data flow of the service of the UE in accordance with the type of the service of the UE; allocating a resource for transmitting the data flow of the service of the UE in accordance with a pre-allocated Signal to Interference plus Noise Ratio SINR; and scheduling a UE in an access queue in accordance with a service priority of the UE and the allocated resource, wherein the simulating a data flow of the service of the UE in accordance with the type of the service of the UE comprises: randomly determining a time interval for transmitting a real-time service in a Transmission Time Interval TTI, and randomly determining an amount of data transmitted in the time interval; and determining, in accordance with a random distribution, an amount of data transmitted for a non-real-time service in a TTI, by: determining the type of the service; in response to the service being a streaming service, generating an eligible amount of data per TTI in accordance with the random distribution; in response to the service being a session-type service, randomly generating an interval for transmitting data of the session-type service, as well as an amount of data transmitted on the interval. in a network constructed according to a network planning parameter, performing access scheduling on a User Equipment UE in accordance with a type of a service of the UE;
