A method of utilizing hierarchies for managing policies for wireless traffic optimization in a wireless network (106, 108), the method comprising: defining a first policy set among the policies as global policies, wherein the global policies are deployed to most or all mobile devices in the wireless network (106, 108); defining a second policy set among the policies as device policies, wherein the device policies are deployed to mobile devices in the wireless network (106, 108) so that each device policy is provisioned to devices that fit a respective device criteria; and defining a third policy set among the policies as user policies, wherein the user policies are deployed to mobile devices (106, 108) in the wireless network so that each user policy is provisioned to a specific user's device or a specific group of user devices; the method being characterized in that there is a hierarchy among the global, device and user policies so that user policies have a higher priority than device policies and global policies, and so that device policies have a higher priority than global policies; and in that the method further comprises: deploying the policies of the first policy set, referred to hereinafter as the global policies to the mobile devices in the wireless network (106, 108); deploying the policies of the second policy set, referred to hereinafter as the device policies, to a first subset of mobile devices in the wireless network (106, 108), wherein the first subset of mobile devices meet a device criteria; determining whether any device policy conflicts with any global policy on any of the first subset of mobile devices, and if so, overwriting the conflicting global policy with the conflicting device policy on the first subset of mobile devices; deploying the policies of the third policy set, referred to hereinafter as the user policies, to a second subset of mobile devices in the wireless network (106, 108), wherein the second subset of mobile devices includes a specific user's device or a specific group of user devices; and determining whether any user policy conflicts with any device policy or any global policy on any of the second subset of mobile devices, and if so, overwriting the conflicting global policy and/or the conflicting device policy with the conflicting user policy on applicable mobile devices in the second subset of mobile devices. defining a first policy set among the policies as global policies, wherein the global policies are deployed to most or all mobile devices in the wireless network (106, 108); defining a second policy set among the policies as device policies, wherein the device policies are deployed to mobile devices in the wireless network (106, 108) so that each device policy is provisioned to devices that fit a respective device criteria; and defining a third policy set among the policies as user policies, wherein the user policies are deployed to mobile devices (106, 108) in the wireless network so that each user policy is provisioned to a specific user's device or a specific group of user devices; the method being characterized in that there is a hierarchy among the global, device and user policies so that user policies have a higher priority than device policies and global policies, and so that device policies have a higher priority than global policies; and in that the method further comprises: deploying the policies of the first policy set, referred to hereinafter as the global policies to the mobile devices in the wireless network (106, 108); deploying the policies of the second policy set, referred to hereinafter as the device policies, to a first subset of mobile devices in the wireless network (106, 108), wherein the first subset of mobile devices meet a device criteria; determining whether any device policy conflicts with any global policy on any of the first subset of mobile devices, and if so, overwriting the conflicting global policy with the conflicting device policy on the first subset of mobile devices; deploying the policies of the third policy set, referred to hereinafter as the user policies, to a second subset of mobile devices in the wireless network (106, 108), wherein the second subset of mobile devices includes a specific user's device or a specific group of user devices; and determining whether any user policy conflicts with any device policy or any global policy on any of the second subset of mobile devices, and if so, overwriting the conflicting global policy and/or the conflicting device policy with the conflicting user policy on applicable mobile devices in the second subset of mobile devices.
