20110022834 | SYSTEMS AND METHODS FOR SHARED SECRET DATA GENERATION - Disclosed examples of secure communications involve generating, by a mobile communication network device, a shared secret data having a length of M units. A first operation on groups of one of N units of a randomly generated base shared secret data and one of a plurality of secret values thereby generates a plurality of first operation results. A second operation on a select plurality of the first operation results generates a plurality of second operation results. The randomly generated base shared secret data can have a length of N units, where N is less than M. The shared secret data is constructed from at least one of the first operation results and the plurality of second operation results. | 01-27-2011 |
20130163444 | MULTICAST RESOURCE OPTIMIZATION - Content may be transmitted to mobile devices, in a network, using a Multimedia Broadcast Multicast Services (MBMS) multicast technique over wireless interfaces in the network. In one implementation, network elements in the network may receive feedback about the MBMS multicast transmission, where the feedback relates to a quality of the content, as received by the one or more mobile devices, or to the quality of the radio channel. The devices may determine whether to modify transmission parameters relating to the MBMS multicast transmission and may determine whether to retransmit lost data, corresponding to the content, to the mobile devices. The lost data may be retransmitted as a unicast transmission or a multicast transmission. | 06-27-2013 |
20140126469 | LIMITING OF PACKET DATA NETWORK CONNECTION REQUESTS FOR WIRELESS DEVICES - Packet data network (PDN) connection requests from a mobile device may be limited by the mobile device. In one implementation, the mobile device may track an amount of successful PDN connection requests issued by the mobile device over a cellular network and maintain a timer value relating to an amount of time over which the successful PDN connection requests have been tracked. The mobile device may determine an allowable number of PDN connection requests and compare the amount of successful PDN connection requests to the allowable number of PDN connection requests. The mobile device may determine, based on the comparison, whether to block a PDN connection request from being issued to the cellular network. | 05-08-2014 |
20140310398 | CLASSIFYING CLIENT DEVICES IN A NETWORK - One or more devices may receive attribute information identifying multiple attributes associated with a client device; classify the client device based on the attribute information; and provide, based on classifying the client device, classification information to a network device to cause the network device to associate a particular policy set, of multiple policy sets, with the client device. The classification information may identify a classification of the client device. The particular policy set may be based on the classification of the client device and may include an instruction used to process a data flow provided to or provided from the client device. | 10-16-2014 |
20140379935 | MOBILE DEVICE PERCEPTIVE AUDIO AND VIDEO QUALITY ANALYSIS USING ONBOARD TEST SIGNALS - Techniques described herein may use perceptual quality measurement techniques to test and/or evaluate communication sessions between mobile devices. A method may include receiving, by a mobile device and as part of an audio or video call with a second mobile device, a streamed version of a reference audio or video file; and reading a version of the reference audio or video file that was previously stored locally to the mobile device. The method may further include calculating, based on a comparison of the streamed version of the reference audio or video file to the version of the reference audio video file that was stored locally, a perceptual quality score for the streamed version of the reference audio or video file. | 12-25-2014 |
20150038110 | RESOURCE-BASED BILLING AND MONITORING FOR M2M - A device may obtain resource utilization data associated with a machine-to-machine device. The resource utilization data may include information identifying a quantity of data transmitted by the machine-to-machine device during a particular period of time, and an amount of network resources utilized by the machine-to-machine device during the particular period of time. The device may determine a billing metric based on the quantity of data and the amount of network resources utilized by the machine-to-machine device. The device may determine, based on the billing metric, a cost associated with the amount of network resources utilized by the machine-to-machine device. The device may charge the fee associated with the utilization of the network resources by the machine-to-machine device to an account of a subscriber associated with the machine-to-machine device. | 02-05-2015 |
20150117184 | MANAGEMENT OF ACCESS NETWORK RETRY ACROSS POWER CYCLE - A device creates a list of permanent evolved packet system (EPS) mobility management (EMM) failure events associated with the device, where the list includes information associated with one or more permanent EMM failure events encountered by the device. The device stores the list of permanent EMM failure events, provides an attach request message to an access network, and receives, from the access network, a reject message as a response to the attach request message. The device performs a power cycle based on receiving the reject message, and erases, based on the power cycle, a forbidden public land mobile network (PLMN) list and a forbidden tracking area list maintained by the device. The device repopulates the forbidden PLMN list and the forbidden tracking area list with information included in the list of permanent EMM failure events. | 04-30-2015 |
20150186564 | NETWORK DEVICE AND CALL SIMULATION TOOL - A first network device executing a device simulation tool receives a selection of a second network device in a communications network. The first network device receives a selection of at least one use case, scenario or error condition associated with operation of the second network device or the communications network, and executes a network simulation of the communications network based on the at least one use case, scenario or error condition. The first network device generates a call flow diagram, which involves the selected second network device, based on the executed network simulation, and provides a graphical display of the generated call flow diagram. | 07-02-2015 |
20150189525 | METHOD AND SYSTEM FOR PLATFORM-BASED DEVICE FIELD TESTS - An approach for receiving an input for specifying one or more parameters for evaluating a device under testing. The approach further involves generating a test route based on the input, wherein the test route represents a test environment in which the device under testing is expected to be subjected to the one or more parameters. | 07-02-2015 |
