Examples of methods, systems, and computer program products relating to supervising data in a wireless network are disclosed. At least part of a system may be located between a packet data network and a base station, and/or may be at least logically separate from the base station. The system may be capable of performing a method of reducing a time period for a packet to travel to a respective user equipment in a wireless network comprising: estimating a parameter indicative of service by a base station; at least partly based on said estimated parameter, determining whether or not to delay arrival at the base station of at least one other data packet so as to reduce the time period for the packet to travel to the respective user equipment; and if determined to delay, delaying of arrival of the at least one other data packet.
