A wireless detection device receives a user input indicating at least one wireless communication network service. The detection device processes the user input to select a pseudo-pilot signal configuration. The detection device wirelessly transmits a pseudo-pilot signal having the selected pseudo-pilot signal configuration. The detection device wirelessly receives a device identifier from a wireless communication device responsive to the pseudo-pilot signal. The detection device stores data indicating the device identifier and a time when the device identifier was received from the wireless communication device. The detection device may transfer the data to a control system or display the data to the user.

Wireless communication device detection with a pseudo-pilot signal

Systems, methods, and software for operating a wireless communication system are provided herein. In one example, method of operating a wireless communication system is provided. The method includes processing a voice call directed to a user device and alerting the user device of the voice call, determining that the user device has not answered the voice call, and determining a status of the wireless communication system. When the status of the wireless communication system indicates a first condition, then the method includes initiating a first connection for the voice call to a voicemail service for the wireless communication system. When the status of the wireless communication system indicates a second condition, then the method includes initiating a second connection for the voice call to a voicemail service on the user device.

Conditional voicemail routing in wireless communication networks

Security in an asymmetrical network is addressed. At a security element, a handshake message is received on a path within the asymmetrical network. The handshake message is associated with an attempt to establish a session. A determination is made as to whether there is an entry for the handshake message in a local state table. When there is no entry in the local state table, then an entry is generated in the local state table, a notification of the handshake message is sent to a centralized computing platform that tracks handshake messages received by a plurality of security elements in the asymmetrical network, and the handshake message is allowed to pass along the path. A notification is received from the centralized computing platform that the session associated with the handshake message is allowed, based on associated handshake messages received at the centralized computing platform.

Addressing security in asymmetrical networks

Embodiments disclosed herein provide systems and methods for dynamically selecting a wireless transceiver in a wireless communication device. In a particular embodiment, a method operating a wireless communication device having multiple wireless transceivers provides exchanging wireless media communications with a first communication network using a first one of the wireless transceivers. The method further provides processing a data structure of access connections and instructions to select a wireless data connection in a second communication network, wherein the instructions are associated with a wireless data service of the second communication network in the data structure, and processing one of the instructions to disable the first wireless transceiver. The method further provides exchanging additional wireless media communications with the second communication network using a second one of the wireless transceivers.

Dynamic wireless transceiver selection in a wireless communication device

Wireless networks comprise base stations that each have communication ports. The wireless networks exchange media with user devices through the communication ports. The wireless networks are identified by Ethernet OUIs, and the base stations and ports are identified by unique codes. An Ethernet backhaul network exchanges the media in Ethernet frames between the communication ports. The Ethernet backhaul network routes the Ethernet frames based on MAC addresses that indicate a destination OUI, a destination base station code, a destination port code, a source OUI, a source base station code, and a source port code.

Ethernet backhaul for wireless base stations

Systems, methods, and computer-readable media for assigning priority to scalable video codings are provided. In one method, the dependency_id, quality_id, and temporal_id of a NAL unit header is used to calculate the priorty_id for the NAL unit header. In another method, the DiffServe field of an IP packet is modified based on the priority markings of the NAL unit header to provide different levels of assured forwarding.

Scalable video coding priority marking

Addressing security in an asymmetrical network. At a centralized database, a handshake message is received from a security element that received the message on a first path. A second handshake message is received from a second security element that received the second message on a second path, where the centralized database tracks handshake messages and associations between the messages and communication sessions. A determination is made that the first message is associated with a session. Another determination is made that the second message is associated with the same session. An association between the second message and the first message is stored in the centralized database, based on the associations of the first message and the second message with the same communication session. A determination that the communication session is allowed is stored in the centralized database, based on the association of the second handshake message to the first handshake message.

A method and system are provided for centralizing services subscribed to by customers of a service provider for detecting attacks at the customer-end of a communications network. A signal diverter is installed in a signal path carrying inbound communication signals common to subscribed customers and a portion of the collective inbound signals for each customer is diverted to a detection apparatus. Finally, based on parameters for each subscribed customer, a determination is made as to if a subscribed customer is experiencing an attack.

Shared tap DOS-attack protection

A method and system are provided for preventing network service shutdowns resulting from denial of service (DOS) attacks. First, parameters are monitored corresponding to network elements carrying communication signal traffic in a communications network, and, based on the parameters, if a DOS attack is indicated, performing the following for each instance of communication signal traffic: accessing data structures for data relating to protected communication signal traffic, and, based on the data, determining if the communication signal traffic is designated as protected. Finally; based on the determination, cleaning and forwarding each protected communication signal to its respective destination.

Detecting and addressing network attacks

Embodiments of the present invention provide systems, methods and apparatuses for addressing security by keeping track of handshake messages received by security elements along paths in an asymmetrical network. An Intelligent Security System receives handshake messages, thereby determining whether a session is allowed, and communicating information about the handshake messages, associations, and allowed sessions, to the security elements.
