    Abstract: A method and apparatus for user data traffic handling for an EVDO enabled hybrid mode mobile device, the method having the steps of: blocking a system selection at the mobile device until no EVDO traffic state exists, the blocking step includes either monitoring whether a user changes a scan mode on the mobile device; and if the user changes the scan mode, checking whether the mobile device is in an EVDO traffic state; and if yes delaying a system selection until the EVDO traffic state is ended, or monitoring whether a user is in an EVDO traffic state, and if yes, preventing a user from accessing a scan mode menu on the mobile device.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 根据本申请的技术的实施例，当无线数据设备和无线数据网络之间没有数据业务时，无线数据设备或其他数据节点周期性地向无线网关（例如PDSN）发送请求消息。 每个请求消息复位无线网关上的简单IP不活动定时器。 当多个无线数据设备发送请求消息时，随机发送请求消息的后续传输间隔，以减少与同一无线链路上的其他设备的请求相冲突的概率。 例如，请求定时器可以基于无线网络上的简单IP不活动定时器设置，以及无线数据网络服务的无线数据设备的数量。 在无线数据设备或其他数据节点处的请求定时器的到期导致下一个请求消息从无线数据设备或代表无线数据设备发送。
