20090124262 | EFFICIENT NEIGHBOR LIST CREATION FOR CELLULAR NETWORKS - A method of constructing a neighbor list for a plurality of sectors in a cellular communication environment sorts reference neighbor pairs in the network by number of occurrences based on data derived from one or more PSMM transmissions, analyzes pairs in the sorted list and determines for each pair whether a percentage of occurrence exceeds a first threshold and whether a measure of direct transition statistics exceeds a second threshold. If the percentage of occurrence exceeds a first threshold and the measure of direct transition statistics exceeds a second threshold, then if the reference's neighbor list and reciprocal neighbor list have fewer than a predetermined number of neighbors, the process adds neighbors to the reference's NL and reciprocal NL in order of occurrence percentage to create a final neighbor list. | 05-14-2009 |
20090168726 | ENHANCED CONFIGURATION AND HANDOFF SCHEME FOR FEMTO SYSTEMS - The enhanced configuration and handoff scheme leverages the configuration of the Femto system, the Femto access network conditions and the mobile device conditions to facilitate an attractive user-experience. In an embodiment the invention is based on the use of the access network conditions, IP (Internet Protocol) multimedia service QoS constraints, and the user profile for an enhanced configuration and handoff scheme, in a multimode Femto system. | 07-02-2009 |
20090171717 | APPLICATIONS OF CLUSTER ANALYSIS FOR CELLULAR OPERATORS - Subscriber travel behavior is defined using cellular call location data. The defined travel behavior is used to segment the customer population. In a further aspect of the disclosed principles, a method to consolidate numerous of price plans is disclosed wherein price plans are grouped using cluster analysis. In the context of this disclosure, the term “cluster analysis” encompasses a number of different algorithms and methods for grouping objects of similar kind into respective categories to thus organize observed data into meaningful structures. In this context, cluster analysis is a data analysis process for sorting different objects into groups in a way that the degree of association between two objects is maximal if they belong to the same group and minimal otherwise. | 07-02-2009 |
20090172782 | Service Utilization Control Manager - Aspects of the invention allow mobile network users as well as mobile network providers to define policies that are managed across several applications and services. Thus, several application servers and network elements are coordinated to implement a service policy. More specifically, aspects of the invention define service level policies for any service be within an IMS based or non-IMS based wireless network implemented by SIP or non-SIP network elements. | 07-02-2009 |
20100066306 | MOBILE TELEPHONE CHARGER WITH PROMOTIONAL AUDIO OUTPUT - A mobile telephone charger capable of reproducing a promotional audio tune is provided comprising a housing, a power input connector attached to the housing for receiving an electrical power input, a power output connector attached to the housing for charging a mobile telephone responsive to the electrical power input, a power detector module for generating an enabling signal in response to detecting the electrical power input, an audio chip module responsive to the enabling signal for generating a predetermined audio signal, the predetermined audio signal corresponding to audio data stored in a computer readable medium disposed in the mobile telephone charger, and an audio transducer for generating an audio output in response to the predetermined audio signal. | 03-18-2010 |
20100167724 | SYSTEM SELECTION BASED ON SERVICE-SPECIFIC PREFERRED ROAMING LIST IN A WIRELESS NETWORK - A home wireless network is provided that communicates an improved Preferred Roaming List (PRL) that includes service type and service priority indicators for a plurality of wireless service combinations and corresponding roaming networks. Preferably, the service type indicator is a numerical indicator that encodes a combination of multiple wireless services offered by each roaming partner network. In case when more than one roaming network provides the requested wireless service, the service priority indicator provides a priority of selection of roaming networks for a given requested service in accordance with a plurality of parameters. | 07-01-2010 |
20100311416 | SYSTEM AND METHOD FOR LANDLINE REPLACEMENT - A femto cell is provided that automatically routes new communication sessions among the connected mobile and landline handsets based upon local detection of mobile registration with the femto cell, which helps to reduce the backhaul bandwidth requirements and offload backend network processing load. When the mobile handset successfully registers with the femto cell, a User Detection Module at the femto cell routes new calls destined for the mobile telephone number to one or more traditional landline handsets. The femto cell also provides a ring tone to the connected landline handsets for making the outgoing calls. Since the mobile handset remains available for conducting additional communication sessions, the user is able to talk on the landline handset while conducting a simultaneous data session using the mobile phone. | 12-09-2010 |
20100325285 | SYSTEM AND METHOD FOR TEARING DOWN INDIVIDUAL IP COMMUNICATION SESSIONS IN MULTIPLE IP STACK DEVICES - Embodiments of the invention are used to provide a system and method for tearing down and reclaiming an IP address from a multi-IP stack device based on configurable timer parameters that provide a network operator with independent control over each protocol-specific IP network layer session. Dedicated idle and session timers for each IP network layer session are implemented at the network layer of various network nodes in order to independently tear down IPv4 and IPv6 network sessions while maintaining the underlying link layer connection. In embodiments, the IP protocol-specific idle and session timers are processed by the Packet Data Serving Node (PDSN) or the Home Agent (HA). To achieve user session level control of IP protocol-specific network layer sessions, embodiments of the invention provide for storing the network layer idle and session timer attributes at the Authentication, Authorization and Accounting (AAA) server prior to passing such attributes to the PDSN or the HA for processing during the dual-stack communication session. | 12-23-2010 |
20110080839 | DATA PRE-PAID IN SIMPLE IP ROAMING - The described embodiments of the present invention outline two solutions to the problems described above regarding simple IP data access for pre-paid subscribers. The first solutions includes a method for providing pre-paid simple IP data service to a subscriber in a network, including: sending an access request from a point of attachment in an access network capable of providing an IP network access to a home network remote authentication server which deploys a Pre-Paid Client (PPC) and receiving in the point of attachment an access request response from the home network remote authentication server. The second solution includes a method for providing pre-paid simple IP data service to a subscriber in a network, including: sending an access request from a Mobile Station (MS) which deploys a Pre-Paid Client (PPC) to a home network remote authentication server and receiving in the MS an access request response from the home network remote authentication server. | 04-07-2011 |
