Embodiment Construction

[0024] Figures 1 through 1 are used in this patent document to describe the principles of the invention, which will be discussed below. Figure 4 And the examples are for illustration only and should not be construed as limiting the scope of the present invention in any way. Those skilled in the art will understand that the principles of the invention may be implemented in any suitably arranged wireless communication network.

[0025] Figure 1 shows an exemplary wireless network in which a Supplementary Channel (SCH) can be dynamically assigned to a single mobile station in accordance with the principles of the present invention. The wireless network 100 includes a plurality of cell sites 121-123, each of which includes one of a plurality of base stations, namely a first BS 101, a second BS 102 or a third BS 103. Base stations 101-103 communicate with a plurality of mobile stations (MS) 111-114 via Code Division Multiple Access (CDMA) channels according to the IS-2000-C stand...

Abstract

A wireless network that provides a packet data call connection between a source mobile station (MS) and a destination mobile station (MS) in a coverage area of the wireless network. The wireless network comprises a first base station that wirelessly communicates with the source mobile station, a second base station that wirelessly communicates with the destination mobile station, and a mobile switching center that connecting the first and second base stations. The first base station receives a first message from the source mobile station requesting a MS-MS packet data call connection to the destination mobile station. In response to the first message, the first base station initiates establishment of the MS-MS packet data call connection on a local IP network coupling the first and second base stations.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a system and related method for packet data calls between mobile stations in a wireless network. Background technique [0002] Wireless communication systems have been ubiquitous in society. A wide variety of fixed and mobile wireless terminals are used by businesses and consumers, including cellular telephones, pagers, Personal Communications Services (PCS) systems, and fixed wireless access equipment (ie, vending machines with cellular capabilities). Wireless service providers are constantly attempting to create new wireless device markets and expand existing ones by making wireless devices and services cheaper and more reliable. The price of wireless devices has dropped to such a point that these devices are affordable to almost everyone, and the price of wireless devices is only a small fraction of the total cost incurred by the user (subscriber). In order to const...
