A packetised data network includes IP telephones (ITs) and a network intelligence (NI). All of the keys of each IT are 'soft' keys (i.e., they have no fixed function). The NI associates a configuration data structure with the IT which correlates the keys with functions, and, based on this, may control the display of the IT to indicate the current function of certain of the soft keys. Some of the functions are requests for data services at the telephone (e.g., video or programmed audio over the internet). When a user requests such a service with a key press, the NI sets up the service between the data source and the telephone. This may require associating a new configuration data structure with the keys of the IT. The IT user may activate multiple data services through the NI.

Telephony and data network services at a telephone

A mobile communications device includes a communication subsystem operable to conduct a plurality of wireless data connections between the mobile communications device and a wireless network wherein each of the data connections is associated with a connected application operating on the mobile communications device. A processor, coupled to the communication subsystem, is configured to process requests for new wireless data connections for a plurality of applications, releasing existing data connections and establishing new wireless data connections between the mobile communications device and a wireless network. The mobile communications device also includes means for prompting a user of the mobile communications device for releasing at least one application having an existing wireless data connection upon determining that a further wireless data connection cannot be effected when a request for a new wireless data connection for an application is received.

System and method for resolving contention among applications requiring data connections between a mobile communications device and a wireless network

One illustrative method for use in efficiently establishing a data connection, such as a Packet Data Protocol (PDP) Context, between a mobile station and a wireless communication network includes the steps of causing at least one data connection request to be transmitted to the wireless network in attempt to establish a data connection between the mobile station and the wireless network; setting a delay timer to an initial value and running the delay timer; if the data connection has not been established in response to transmitting the at least one data connection request, causing at least one subsequent data connection request to be transmitted after expiration of the delay timer set to the initial value; setting the delay timer to a subsequent initial value which is greater than the initial value and running the delay timer; and if the data connection has not been established in response to transmitting the at least one subsequent data connection request, causing at least one other subsequent data connection request to be transmitted after expiration of the delay timer set to the subsequent initial value. This technique continues until the data connection is established with the wireless network, if at all. If a new wireless network is selected during the technique, the process is reset such that the first initial value is again utilized first for the delay timer. Preferably, the technique works in combination with relatively more quick retries implemented in lower radio layer(s) (i.e. the physical, data link, or network layer). Thus, each data connection request may be a plurality of data connection retries which are performed much closer together in time than other retry attempts.

A cellular communications system may include at least one base station and at least one mobile cellular communications device. More particularly, the at least one mobile cellular communications device may include a controller, at least one user input device connected to the controller, and a wireless transceiver cooperating with the controller for attempting to establish a wireless communications link with at least one base station, and if the wireless communications link cannot be established, then continuing to attempt to establish the wireless communications link at a first attempt rate. Moreover, if a user provides a request to access the at least one base station via the at least one user input device, then the controller may continue to attempt to establish the wireless communications link based upon a second attempt rate greater than the first attempt rate.

Cellular communications system providing mobile cellular device battery saving features while accommodating user access requests and related methods

A cellular communications system may include at least one base station selectively denying attempts to establish wireless communications links therewith, and wirelessly transmitting denial messages for denied attempts. The system may further include at least one mobile cellular communications device including a wireless transceiver and a controller cooperating therewith for attempting to establish a wireless communications link with the at least one base station having a quality of service (QoS) level associated therewith. If a denial message is received, the controller continues to attempt to establish the wireless communications link at a first attempt rate. Yet, if the wireless communications link cannot be established with the desired QoS level, and if no denial message is received, then the controller continues to attempt to establish the wireless communications link at a second attempt rate different than the first attempt rate.

A mobile communications device () includes a wireless transceiver () operable to conduct at least two data connections between the mobile communications device () and a wireless network () wherein each of the data connections is associated with a connected application operating on the mobile communications device. A processor () is coupled to the wireless transceiver (). The processor () is operable to process a request for a data connection for an unconnected application operable on the mobile communications device (), to release one of the data connections associated with one of the connected applications and to establish a data connection between the mobile communications device () and the wireless network () for the unconnected application. A contention manager () is operable to select the connected application to be released based upon a comparison of a contention parameter associated with each of the connected applications.

A method and apparatus for saving network resources in a CDMA2000 network, the method comprising the steps of receiving a data packet for a wireless data device at a base station controller in the CDMA2000 network; determining a frame transport capability of a forward common channel; checking whether the data packet falls within the frame transport capability; and if the data packet falls within the frame transport capability, encapsulating the data packet as a data burst message; and sending the data burst message over the forward common channel, wherein the sending step over the forward common channel precludes a dedicated data traffic channel being established for the data packet thereby saving network resources on the CDMA2000 network.

The processor is further operable to reestablish the PDP context associated with the first application responsive to a second input received from the user.
