Abstract: A system may be configured to determine a floor of a building in which the user device is located at a time a call was placed. The information, indicating the determined floor, may be provided to a callee, such as a public safety answering point (“PSAP”). The floor may be determined based on, for example, comparing an altitude of the user device and/or a list of networks or devices that are visible to the user device, to a set of reference information.

Abstract: A first device may receive a service authorization instruction from a second device. The service authorization instruction may include one or more authorization parameters and an instruction to associate or disassociate a key, with a service, to permit or prevent the service to be accessed using the key. The key may be embedded in an application used to provide an application instruction corresponding to a request for the service. The first device may validate the service authorization instruction based on the one or more authorization parameters; and update, based on validating the service authorization instruction, information identifying services that are accessible using the key to permit or prevent the service to be accessed using the key without modifying the key embedded in the application.

Abstract: Digital signal processors (DSPs) process the digital baseband signals associated with CPRI links between BBUs and RRHs. The DSPs may be implemented at the RRH nodes (e.g., at the link leading to the BBU node), at the BBU node (e.g., at the links leading to the RRH nodes), or at both. The DSPs may be used to increase performance of the RAN. For example, the DSPs may implement digital filters designed to enhance the performance of the RAN.

Abstract: A server device may receive information identifying property features relating to for-sale properties; identify a plurality of properties having one or more of the property features; identify particular properties, of the plurality of properties, having the one or more of the property features; receive location information for the particular properties; and generate, based on the location information, a trip plan identifying the particular properties. The trip plan may identify a sequence in which the particular properties should be visited and a route that should be taken when traveling between the particular properties. The server device may store or output the trip plan.

Abstract: One or more first servers may receive a token, generated by a second server based on the second server validating an authorization parameter received by a third server; receive, from the second server, a token parameter, associated with the token and being associated with the authorization parameter and identifying a credential associated with the third server; receive, from the third server, a request to update the credential, the request including the token; validate the token; form an updated credential based on the token parameter and based on validating the token; and provide the updated credential to the third server. The credential may be replaced, by the third server, with the updated credential without interaction with a user of the third server.

Abstract: A system may be configured to request, from a user device, consent for an application server to output one or more messages to the user device. When requesting the consent, the system may output a consent message associated with the application server. The system may receive, from the user device, an indication of consent, the indication being sent by the user device based on the consent message; and enforce, by the consent gateway device, the consent indicated by the user device. When enforcing the consent, the system may allow or disallow application traffic, from the application server, based on the indication of consent. The application traffic may be associated with the user device.

Abstract: A network device receives utilization information, for an infrastructure network, that provides data for individual segments of the infrastructure network. Based on the data for the individual segments, the network device generates a costing matrix that includes prices for each segment of the individual segments. The network device identifies particular segments of the infrastructure network associated with an end-to-end path for a subscriber and generates pricing of different service levels for the end-to-end path. The pricing is based on the costing matrix and a particular time period. The network device provides, to the subscriber, a user interface that includes service plan options with the pricing of different service levels for the end-to-end path and receives, via the user interface, a selection of one of the service plan options. The network device sends instructions to provision the infrastructure network to support the selected service plan option.

Abstract: An emergency message handling system may manage emergency SMS text messages sent by wireless mobile communication devices, such as to 911. Each message may be sent to an emergency call service having a TTY messaging system. The emergency message handling system may include an SMS network interface, a computer processing system, and a TTY network interface. The SMS network interface may be configured to receive the emergency SMS text messages. The computer processing system may include an SMS-To-TTY message converter configured to convert each of the emergency SMS text messages into TTY format. The TTY network interface may be configured to deliver each of the converted emergency SMS text messages in TTY format to the TTY messaging system of the emergency call service to which the emergency SMS text message was sent.

Abstract: A system and method for synchronizing clocks related to telecommunications throughout s point-to-multipoint optical network utilizes downstream data timed using a high frequency transmission clock to distribute timing information of a central telecom-based clock to remote terminals. In an exemplary embodiment, the point-to-multipoint optical network system is an Ethernet-based passive optical network (PON) system that operates in accordance with a Gigabit Ethernet standard. The timing information of the central telecom-based clock is extracted from the downstream data at each remote terminal by recovering the high frequency transmission clock and then, deriving a reference clock, which is synchronized with the central telecom-based clock, from the recovered transmission clock. The reference clock is then used to generate one or more telecom-related clocks that are needed by the remote terminal.
