A system service reloading method, comprising: receiving (S21) a call request for calling a system service that is a network service, wherein the system service includes at least two service processes having same configuration information recording at least port information and socket information; according (S23) to a pre-configured service reloading state, determining whether to perform system service reloading after receiving the call request for calling the system service, wherein the service reloading state includes at least an open state that indicates the system service is in the reloading state and a close state that indicates the system service is not in the reloading state; when the service reloading state is the open state (S25), obtaining a process attribute corresponding to each of the service processes, wherein the process attribute is used to record a creation order of the corresponding service process to distinguish an original service process and a newly created service process among the service processes; and according (S27) to the process attributes, choosing the newly created service process of the service processes in the system service to respond to the call request, wherein, each of the process attributes is in a form of a time parameter recording a service process creation time, choosing the newly created service process of the service processes in the system service to respond to the call request according to the process attributes includes: comparing the time parameters of all service processes with an obtained system time; determining target service processes according to the comparison results, wherein the target service process is a service process that has a positive time difference between its time parameter and the obtained system time; and randomly selecting a target service process among the target service processes as the newly created service process to respond to the call request. receiving (S21) a call request for calling a system service that is a network service, wherein the system service includes at least two service processes having same configuration information recording at least port information and socket information; according (S23) to a pre-configured service reloading state, determining whether to perform system service reloading after receiving the call request for calling the system service, wherein the service reloading state includes at least an open state that indicates the system service is in the reloading state and a close state that indicates the system service is not in the reloading state; when the service reloading state is the open state (S25), obtaining a process attribute corresponding to each of the service processes, wherein the process attribute is used to record a creation order of the corresponding service process to distinguish an original service process and a newly created service process among the service processes; and according (S27) to the process attributes, choosing the newly created service process of the service processes in the system service to respond to the call request, comparing the time parameters of all service processes with an obtained system time; determining target service processes according to the comparison results, wherein the target service process is a service process that has a positive time difference between its time parameter and the obtained system time; and randomly selecting a target service process among the target service processes as the newly created service process to respond to the call request. <EOS>
