Abstract:
A wireless communication device uses an Orthogonal Frequency Division Multiplex (OFDM) resource block structure. The wireless communication device generates and stores data for wireless transmission. The wireless communication device translates an identifier and a current time into one or more OFDM resource blocks that are reserved for use without base station scheduling. The wireless communication device generates one or more authorization marks. The wireless communication device wirelessly transmits the data and the one or more authorization marks in the one or more OFDM resource blocks that are reserved for use without base station scheduling.
Abstract:
A wireless access node to facilitate voice over long term evolution (VoLTE) communication sessions comprises a wireless communication transceiver and a processing system. The wireless communication transceiver is configured to exchange VoLTE packets with a wireless communication device during a VoLTE communication session, and receive a scheduling request and responsively issue a scheduling grant with a number of hybrid automatic repeat requests (HARQs). The processing system is configured to calculate a quality of service (QoS) score based on a communication quality of the VoLTE communication session after issuing the scheduling grant, and if the QoS score falls below a threshold value, apply a lower level of fragmentation to the VoLTE packets.
Abstract:
Systems, methods, and computer-readable media for facilitating call continuity when transferring calls between mobile access networks to voice over internet protocol networks. The method includes recognizing availability of a voice over internet protocol network during a voice call established via a wireless access network. Thereafter, a data connection between a user device and the voice over internet protocol network is established. A transfer of the voice call from the wireless access network to the voice over internet protocol network is initiated by initiating a three-way call. Such a three-way call includes a first portion routed to a destination device via a public switch telephone network and a second portion routed to the user device via the voice over internet protocol network.
Abstract:
A Long Term Evolution (LTE) Serving Gateway (S-GW) to indicate mode transitions of a wireless communication device comprises a communication transceiver and a processing system. The communication transceiver is configured to establish a default bearer between the LTE S-GW and an LTE Packet Data Network Gateway (P-GW) for the wireless communication device, establish a bearer channel between an LTE access node and the LTE S-GW, and exchange data over the bearer channel responsive to the wireless communication device entering an active mode. The processing system is configured to release the bearer channel between the LTE access node and the LTE S-GW responsive to the wireless communication device entering an idle mode, generate mode transition records indicating idle-to-active mode transitions and indicating active-to-idle mode transitions of the wireless communication device, and direct the communication transceiver to transfer the mode transition records.
Abstract:
A wireless base station schedules allocated resource blocks from an OFDM resource block structure to a UEs and holds unallocated resource blocks from the OFDM resource block structure for machines. The base station decodes wireless OFDM signals based on the OFDM resource block structure to obtain user data from the UEs using the allocated resource blocks and to obtain machine data from the machine devices using the unallocated resource blocks. The base station processes the machine data from the unallocated resource blocks to validate authorization marks in individual resource blocks. The base station transfers portions of the machine data having the valid authorization marks for delivery. The base station inhibits the transfer of machine data not having the valid authorization marks.

Abstract:
Portable mobile devices may have ambient light sensors (ALS) capable of modulating the level of backlight on the display of the portable electronic device in various environmental situations. The ALS is capable of receiving an infrared signal or a visible light signal that may then be read to determine an end and a beginning, and parsed to extract the code. The information sent from the infrared or visible light source to the portable electronic device may be handled by the device in various ways including direct processing and display to present the user of the portable electronic device with a coupon, offer, or other benefit. This may occur in several ways including displaying a coupon or an offer, launching a URL or URI, or launching an application on the portable electronic device.
