A wireless packet data communications system that includes a number of modem pool transceivers (MPTs), one or more modem pool controllers (MPCs), and one or more servers. Each MPT receives and processes data packets to generate a modulated signal (e.g., a CDMA spread spectrum signal) suitable for transmission over a terrestrial communications link. Each MPC provides call related processing for one or more MPTs. The servers couple to the MPTs and MPCs via an Internet Protocol (IP) back-bone and provide management of the communications system. The IP back-bone further interconnects the MPTs with one or more data networks and includes a number of routers that route data packets between the data networks and the MPTs. Each MPT can couple to two or more routers for redundancy. Each MPT is operated as an element in an IP network and is associated with an IP address that identifies the MPT. One to three MPTs can be deployed at each cell site to provide wireless data service coverage for up to three sectors at the cell site. The MPCs can either be centralized and coupled to the MPTs via the IP back-bone or distributed about the communications system.

An improved method and system for accessing wireless data services that reduce messaging and enable roaming subscribers to access data services are described. A wireless communication system in accordance with the present invention includes at least a service control point and a gateway system (e.g., a Gateway Generalized Packet Radio Service Serving Node (GGSN)) that is coupled to a data network. To obtain access to data services, a wireless subscriber unit establishes communication with a gateway system and requests data services from the gateway system. In response to the request, the gateway system queries the service control point regarding authorized data services for the subscriber unit. If the gateway system receives a negative reply from the service control point, then the gateway system denies access to the data services by the subscriber Unit. However, if the gateway system receives a positive reply from the service control point, then the gateway system enables access to the data services by the subscriber unit. In a preferred embodiment, the gateway system tracks the requested data services utilizing pre-defined resource units. In one embodiment, the gateway system tracks service utilization by periodically querying and receiving a reply from the service control point after each pre-defined resource unit has been utilized. In this embodiment, the service control point updates an account balance of remaining resource units in response to receiving the queries and informs the gateway system when data access should be denied.

Wireless data services such as wireless email are becoming common, and in particular, “always-on” systems, where new email is automatically forwarded by the service provider to the wireless device. The problem is that there is no effective mechanism for implementing “always-on” systems when the user is moving around a network, or from one network to another. The invention addresses this problem by generating a session key at the service provider's system for a given data session, and returning this session key to the mobile device. Each time the mobile device communicates with the service provider, it enters this session key into a field that will simply pass through the communication network to the service provider. This allows the service provider to manage the data session, preparing proper accounting records and directing the deletion of stale data sessions on network resources.

A mobile station attempts to access wireless data services such as WAP applications via a data call, by first transmitting a session request to a wireless network, where the session request identifies an initial data bearer that should be used to establish the session. Upon receiving notification that the network is unable to establish the data session using the initial data bearer, the mobile station accesses a bearer table stored in its memory, selects an alternate data bearer which may be the next best data bearer, and automatically reattempts the data call without user intervention. The process repeats until the session is successfully established using one of the data bearers in the bearer table, or until the occurrence of a terminating event, such as cancellation of the data call by the user of the mobile station, or expiration of a predetermined time limit.
