Abstract: A method for paying back customers for unused service units remaining after a billing cycle. A payback amount is determined by the product of the number of unused service units remaining and the payback rate amount. The payback amount credited to the customer is the calculated payback rate or a maximum payback amount, wherever is smaller. A total payback amount can be determined based on a combination of payback amounts for various services, including voice services, texting services, email services, and/or data storage services.

Abstract: A method used in a receiver includes measuring first Received Signal Strength Indications (RSSIs) in respective first communication channels, which are located in a given frequency band and which each have a first channel bandwidth. Based on the first RSSIs, second RSSIs are computed for respective second communication channels, which are located in the given frequency band and which each have a second channel bandwidth that is larger than the first channel bandwidth. At least one of the first and second communication channels over which to receive signals at the receiver are selected using the first and second RSSIs.

Abstract: A method for improved system selection by wireless mobile devices in 3GPP networks is provided. Location data is retrieved by the wireless device to estimate an initial system on which the wireless mobile device will attempt initialization. Using the location data, an absolute radio frequency channel number (ARFCN) associated with the location data is determined from an ARFCN table stored in memory in the wireless mobile device. The wireless mobile device can then perform system selection using the determined ARFCN. A server generates and maintains the ARFCN table which is initially provided to the wireless mobile device at manufacturer, during provisioning or as an over-the-air update.

Abstract: A method for locating a wireless communications device WCD (102). The method includes the step of receiving at the WCD (102) a wireless transmission comprising a first auto-location trigger signal. The WCD (102), responsive to the first auto-location trigger signal, operates in an auto-location mode. The auto-location mode includes the automatic collection and communication of predetermined first data, such as audio, video, and GPS location data. After the automatic collection and communication step of the first data is complete, the WCD (102) enters into a standby mode. The standby mode continues until a state detection device (206) of the WCD (102) detects a change in the state of the WCD (102). These changes in state are exclusive of the wireless transmission comprising the first auto-location trigger signal. The change(s) in state produce a second auto-location trigger signal, which causes the automatic collection and communication of a second data that is the same or similar to the first data.

Abstract: A MOAF algorithm is used to resize cells for balancing capacity. The MOAF algorithm bases its decision on a cell and all other cells which the algorithm decides are sufficiently close in a propagation sense to affect the results. The MOAF algorithm also automatically determines those cells in an area which are most heavily loaded and those cells which are lightly loaded. The MOAF algorithm will only decrease the size of a cell if it determines specific adjacent cells that are willing and able to accept the load, and the MOAF algorithm will increase the size of a cell only if there is a nearby heavily loaded cell that requires the removal of load. Moreover, the MOAF algorithm can be tuned (via the threshold parameter T) to shift the focus of the optimization from avoidance of coverage holes to the avoidance of creation of excessive handover legs.

A report of at least one proposed rate plan is then produced and provided to the subscriber, which enables selection of a best telecommunication service provider.

Abstract: Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, ?, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.

Abstract: A wireless communication system broadcasts a control signal at a first frequency band from a base station and allocates additional frequency band(s) for transmitting data via terminal(s). A control signal at the first frequency band indicates the location of the additional frequency band(s) and is not transmitted over the additional frequency band(s). Wireless data transmission is simultaneously performed over the first frequency band and the additional frequency band(s). Each terminal receives the control signal, which is used in time-synchronizing frames between the wireless data transmission at the first frequency band and the wireless data transmission at the additional frequency band(s). The control signal also includes control data for managing wireless data transmission between the base station and the terminal(s) at the first frequency band, and is utilized instead of a control signal at the additional frequency band(s).
