Abstract: A method of initiating a wireless communication session with a communication network is provided. A cost estimate for the communication session is determined based on a quality of service level and a quantity of information to be communicated. The communication session is initiated when the cost estimate is accepted. In one embodiment, the user may select a second quality of service level for the communication session when the first cost estimate is not accepted and is provided a second cost estimate for the second quality of service level. In yet another embodiment, a communication session is initiated when there is sufficient balance available to the wireless communication device or a user's smart card for a communication session at a quality of service level selected by the user. In one embodiment, the method may be performed in accordance with a packet radio service network providing packet data services.

Abstract: A wireless communication device includes an applications processor to operate one or more personal information management (PIM) applications. Upon initial registration or when transiting to a new location, a baseband processor of the device automatically derives the local time using a time-zone database and current location information received from the communication network. The PIM applications operating within the device are updated with the local time. The device may receive location-based services such as advertisements that depend on the current location.

Abstract: Middleware may accommodate both packet data and circuit data services in the same cellular telephone. A cellular telephone may travel between networks that are packet and circuit data service based. A protocol middleware may determine whether packet data services are available, and, if so, may determine the mobility management state of the system. Depending on the mobility management state of the system, inappropriate applications may be closed or suspended.

Abstract: A mobile unit-based system enables real time estimates of charges for both roaming and non-roaming services and for mobile originated and mobile terminated calls in some embodiments. In addition, each of a plurality of contexts or sessions may be separately estimated based on quality of service parameters associated with those sessions. Moreover, mobility management state information may be utilized to estimate the real time charges per session incurred during roaming and non-roaming situations in some embodiments.
