Abstract:
Methods are provided for a multi-mode mobile station to perform multi-mode system selection using a multi-mode system selection algorithm as a function of multi-mode overlay information. The multi-mode overlay information includes a plurality of associations, each association being between a respective set of systems that serve at least a common geographical area, at least some of the associations being between systems using differing radio access technology. Methods are also provided for a system to prepare multi-mode overlay information that includes a plurality of associations and send the multi-mode overlay information to the mobile station.
Abstract:
Methods are provided for transitioning between SIP and MIP. Mobile devices, upon detecting a new system, automatically attempt a MIP session to avoid the default position of SIP. A history is maintained of systems visited, and for systems that did not support MIP in the past, a MIP session is not attempted, but rather SIP is initiated from the start.
Abstract:
Provided are systems and methods for generating a blacklist for femtocells. According to an embodiment of the application, a mobile device generates and maintains a femtocell blacklist including an identification of at least one femtocell to be avoided by the mobile device. Upon detecting a femtocell, the mobile device determines whether the femtocell is identified in the femtocell blacklist. If the femtocell is identified in the femtocell blacklist, then the mobile device avoids any attempt to use the femtocell. This might allow the mobile device to conserve battery power and reduce wireless communication resources. Since the femtocell blacklist is generated and maintained by the mobile device, the network infrastructure does not need to generate and manage the femtocell blacklist. Also, there is no need for the mobile device to download a femtocell blacklist or updates thereof from the network infrastructure.
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:
The present invention provides methods, systems, and devices for selective override of do-not-disturb in a wireless communications network, in which a user is provided with the option to query and modify the ignoring of do-not-disturb (DnD) for certain reasons. In some embodiments, DnD is ignored when an incoming call is an urgent call. In other embodiments DnD is ignored when an incoming call is an emergency call. In some embodiments a call processing server manages and performs selective override of do-not-disturb in an OMA compatible system. In yet other embodiments, a mobile device is adapted to send to a dispatch network a request to query or set an ignoreDnD flag, along with associated ignoreDnD reasons.
Abstract:
A method and apparatus for reverse and forward link dynamic packet transport to and from a wireless data device in a CDMA2000 network, the method comprising the steps of: determining a frame transport capability of a reverse access channel or a forward common channel; checking whether a 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; sending the data burst message over the reverse access channel or forward common channel; receiving the data burst message; and reforming the data packet.

Abstract:
In accordance with the teachings described herein, systems and methods are provided for always-on wireless IP communication. An access provider network (APN) that includes an always-on packet data serving node (PDSN) may be used to communicate over a wireless communication link with a mobile station. The PDSN may include an inactivity timer and may be used to set the inactivity timer to an inactivity timer starting value and send a starting value estimate to the mobile station over the wireless communication link, wherein the starting value estimate is a function of the inactivity timer starting value. The mobile station may include an inactivity timer estimate and may be used to receive the starting value estimate and set the inactivity timer estimate to the starting value estimate. The mobile station may also be used to reset the inactivity timer estimate to the starting value estimate when the mobile station communicates with the APN.
