Base station device, gateway device, call connecting method, and wireless communication system
10721738 · 2020-07-21 · ·

A system is provided which is capable of connecting a call without degrading the security level in a mobile terminal network, even when a call addressed to a user equipment (UE) arrives via the Internet or a home network. A femto base station receives a packet addressed to a UE via the Internet or a home network, and starts a paging procedure. The UE establishes an RRC connection to the femto base station. The UE transmits, to the femto base station, a paging response addressed to the SGSN. The femto base station performs NAS verification. If the femto base station detects the paging response to a paging request that the femto base station itself has issued, the femto base station changes the service type of the service request received from the UE from the paging response to signaling.

Certain aspects of the present disclosure provide an apparatus for wireless communication. The apparatus generally includes an interface configured to obtain at least one voice packet from an access point (AP), wherein the at least one voice packet is obtained during one or more service periods (SPs) of a target wake time (TWT) protocol, and a processing system configured to process the at least one voice packet obtained during the one or more SPs.

Heterogeneous downhole acoustic network

An acoustic network is located in a formation traversed by a borehole having a pipe contained therein. The acoustic network includes a backbone network having a number of backbone modems engaging the pipe and acoustically communicating along the pipe using a first modulation technique. A number of end node modems acoustically communicate using a second modulation technique orthogonal to the first modulation technique. At least one of the backbone modems is a bridge hub modem that is coupled to both the backbone network and an end node modem and communicates with the backbone network using the first modulation technique and with the end node modem using the second modulation technique. The end node modems may have a hibernation mode defined by low energy usage with no transmission or receipt of data, and a transmission mode defined by transmission of data by the end node modem.

SOLAR-POWERED ACCESS POINT FOR LOAD BALANCING NETWORK TRAFFIC ACROSS BACKHAUL NETWORKS
20200213929 · 2020-07-02 ·

A solar-powered device (SPD) node operates as an access point for leaf nodes. The SPD node load balances network traffic received from leaf nodes across different backhaul networks. The SPD node determines a specific backhaul network across which to route the network traffic based on several different factors associated with the SPD node. Those factors include a current battery level, a current solar generation rate, and a current communication link status. The SPD access point also determines the specific backhaul network across which to route the network traffic based on characteristics of the different backhaul networks, including a network latency, among other characteristics.

Methods of combining semi-persistent resource allocation and dynamic resource allocation are provided. Packets, such as VoIP packets, are transmitted on the uplink and downlink using respective semi-persistent resources. For each mobile device, awake periods and sleep periods are defined. The semi-persistent resources are aligned with the awake periods so that most of the time the mobile device can turn of its wireless access radio during the sleep periods. In addition, signalling to request, and to allocate, resources for additional packets are transmitted during the awake periods, and the resources allocated for the additional packets are within the awake windows.

10700856 · 2020-06-30 · ·

A module with an embedded universal integrated circuit card (eUICC) can include a received eUICC profile and a set of cryptographic algorithms. The received eUICC profile can include an initial shared secret key for authentication with a wireless network. The module can receive a key K network token and send a key K module token to the wireless network. The module can use the key K network token, a derived module private key, and a key derivation function to derive a secret shared network key K that supports communication with the wireless network. The wireless network can use the received key K module token, a network private key, and the key derivation function in order to derive the same secret shared network key K derived by the module. The module and the wireless network can subsequently use the mutually derived key K to communicate using traditional wireless network standards.

Reducing power consumption in wireless stations providing network connectivity for embedded devices
10701630 · 2020-06-30 · ·

A system contains a wireless station connected to an embedded device by a wired path, with the wireless station being part of a wireless network. According to an aspect of the present disclosure, the wireless station places a receiver (communicating on the wireless network) in power savings mode upon occurrence of a first condition, and restores the receiver to active mode upon occurrence of a second condition. Such transitions between active and power savings modes are employed while receiving data units from a wireless network and providing the data units to the embedded device. In one embodiment, the first and second conditions correspond to a higher threshold and lower threshold for available data in the memory of the wireless station used for buffering not-yet-transferred data units. In alternative embodiments, the conditions are determined based on corresponding express indications by the embedded device.

ADAPTIVE ROUTE, BI-DIRECTIONAL NETWORK COMMUNICATION
20200205055 · 2020-06-25 ·

In an adaptive route wireless network and bi-directional protocol, each computing device along a route to a gateway appends the previous node's network address to downstream messages as they are transmitted along the route from an originating computing device to the gateway. The list of appended network addresses thus records the route taken by the downstream network message through the adaptive route network. A server computing device maintains a route table including the list of appended network addresses received with each downstream message. To send unsolicited upstream messages to any computing device on the wireless network, the server generates an upstream network message that includes the appended network address(es) from the portion of the route table corresponding to the destination computing device. The upstream route to the destination computing device is thus contained in the list of appended network addresses within the network message.
