摘要： Techniques involving a wireless user device adapted to operate in a carrier network, and associated with a private organization having a private communication network which is not part of the carrier network, are described. The wireless user device gains wireless access via the carrier network and communicates, via the carrier network, with other wireless user devices in a push-to-talk (PTT) voice communication session. The PTT voice communication session is delivered via a carrier processing element of the carrier network, where voice communications of the PTT voice communication session are routed and processed through a private processing element of the private communication network. The voice communications from the wireless user device are assigned and communicated with a generic identifier of the private organization instead of a user identifier of the wireless user device.

摘要： 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.

摘要： A method is performed by a wireless device. The method includes (a) preselecting a set of the base stations; (b) selecting a reverse link cost according to a preselected reverse link cost metric; (c) selecting a base station from the set of base stations; and (d) sending a probe signal at the selected reverse link cost to the selected base station. If a response is not received from the selected base station within a preselected time period and not all the base stations have been sent a probe signal at substantially the selected reverse link cost, then steps (c) through (d) are repeated with a different one of the base stations at substantially the selected reverse link cost. If a response is received from the selected base station within the timeout period, then the responding base station is selected to provide access to the wireless network.

摘要： A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.

摘要： It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.

摘要： 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.

摘要： According to the embodiments of the techniques of this application, a wireless data device or other data node sends solicitation messages periodically to a wireless gateway, such as a PDSN, when there is no data traffic between the wireless data device and a wireless data network. Each solicitation message resets the simple IP inactivity timer on the wireless gateway. When multiple wireless data devices send solicitation messages, the interval between subsequent transmissions of solicitation messages is randomised to reduce the probability of collision with the solicitations from other devices on the same wireless link. The solicitation timer, for instance, may be based on the simple IP inactivity timer setting on the wireless network, and the number of wireless data devices that the wireless data network serves. Expiration of the solicitation timer at the wireless data device or other data node causes the next solicitation message to be sent from or on behalf of the wireless data device.
