In a wireless communications network (10), different service levels can be subscribed to by users of mobile stations (12) for packet-switched communications, such as electronic mail, web browsing, text chat, packet-switched voice communications, and so forth. In one arrangement, two different levels are defined. For a first level, when there is no more data to send over a wireless interface between a mobile station (12) and a wireless access system (14), a logical connection between the mobile station (12) and wireless access system (14) is released. However, at a second level, the logical connection between the mobile station (12) and the wireless access system (14) is not released until after a predetermined timed period from when a send buffer becomes empty, with the send buffer containing data for sending over the wireless interface. |
