  • Patent number: 8538387
    Abstract: Single voicemail for dual-mode phones. Functionality is added to a dual-mode phone such that the dual-mode phone when operating in cellular mode sends a predetermined signal when it answers an incoming call. An enterprise mobility controller, on forwarding a call to the cellular side of a dual-mode phone after failing to complete a Wi-Fi connection, starts a timer. If the mobility controller does not receive the predetermined signal before the timer expires, it assumes that the cellular call has been handed off to the cellular voicemail system, terminates the cellular call, and sends the call to the enterprise voicemail system.

  • Publication number: 20130201978
    Abstract: The present disclosure discloses a method and system for partitioning WLAN in order to separate network traffic from different WLANs. Specifically, a network device receives a packet from a client connected to a first network device on an access network. The network device then determines that the received packet is associated with a VLAN that is pre-configured on the first network device based on the access network to which the client is connected. Furthermore, the network device transmits the packet to a MAC layer switching device, which is not configured with the VLAN that is pre-configured on the network device. The packet includes one of a DHCP discovery message, an ARP request message, a unicast message, a multicast message, and a broadcast message. The unicast message will be transmitted to the second network device on the pre-configured VLAN prior to being transmitted to another network device outside the pre-configured VLAN.

  • Publication number: 20130111066
    Abstract: Automatically configuring split DNS operation in a wireless network device connected to a network. The wireless network device snoops one or more exchanged DHCP messages to obtain domain name(s) associated with the organization that are now used as target domain name suffix(es) for split DNS operations. For subsequent DNS queries, information within the message is analyzed to determine if the request includes a domain delimiter. If no delimiter, the DNS query message is sent to an internal DNS server that is located within an organization. If a delimiter exists, but the domain name in the message matches one of the target domain name suffixes, the DNS query message is sent to the internal DNS server as well. Otherwise, the DNS query message is routed over a different communication path.

  • Publication number: 20130100857
    Abstract: Secure hotspot roaming in wireless networks. An enterprise works with one or more hotspot providers to provide secure access to its clients through hotspot locations. The enterprise provides the (hotspot) service provider (SP), with the addresses of enterprise controllers used for client authentication. The SP maintains a database which maps the enterprise realm to the address of the enterprise controller. When a client connects to a hotspot access point (AP), the hotspot AP sends client information such as MAC address to a SP controller. The SP controller determines if the client is new or already known. If the client is known and the realm associated with the client has an entry in the realm to enterprise database, the hotspot AP is instructed to begin client authentication with the specified enterprise controller. If the client is unknown, authentication begins with the SP controller, and the client is queried for realm information.

  • Publication number: 20130080614
    Abstract: The management of DHCP address leased based on client properties is described. According to a method of operation, clients are managed in a wireless digital network by modifying a requested lease time for an assigned Internet Protocol (IP) address based on properties of a client requesting the lease time. The assigned IP address is released if (i) no communication activity is detected by the client for a prescribed duration or (ii) upon detecting a DHCP Release message from the client. When the DHCP server receives a renewal request, it checks if the client has generated more than a predetermined amount of traffic. If the client has generated traffic exceeding this threshold level, the lease is renewed for a longer period. If the client traffic has not met the threshold level, the lease is renewed with the short lease time.

  • Publication number: 20130036188
    Abstract: Infrastructure-based client management uses synthesized beacon reports to effect client association with APs in a wireless digital network. Beacon reports are synthesized by having a plurality of APs in the network collect client reports and send those reports to a report process on the network. The report process accumulates client reports from the plurality of APs and selects one or more candidate APs to support a client. Selection may be made on reported SNR, AP loading, channel loading, AP characteristics, or a combination. The report process may produce blacklists and optionally whitelists for use by APs to use in processing client probe and connection requests.

  • Publication number: 20130003654
    Abstract: Embodiments of the present disclosure provide for configuring and managing mesh nodes during occasional failure of mesh nodes or addition of new mesh nodes. The disclosed system first determines whether a mesh node is a mesh portal or a mesh point. If it is a mesh portal, the mesh node will advertise its capacity as a mesh portal to other mesh nodes in the network. If it is a mesh point, the mesh node attempts to automatically recover connection to the wireless mesh network if it identifies a unique wireless network based on its associated network identifier. If more than one network identifiers are discovered, the mesh node delays establishing connection to the wireless mesh network until a selection is received.

  • Publication number: 20130007104
    Abstract: Displaying time from a network device according to the time zone of the client. A network device keeps time to a first known time zone, such as UTC, and provides a web server. When a client device makes a request of the network device's webserver, the webserver returns an HTML document which includes code to extract the time zone offset from the client. This may be done for example using the javascript .getTime zone Offset( ) method, through the use of DLLs, or through other programming methods. The document also contains the time at the network device, which is displayed on the client device using the client time zone, and not using the clock or time information in the client device, only using the time zone offset in the client device.

  • Publication number: 20120275320
    Abstract: A system or method that receives a current request from a client, and responds to the current request based on signal strength associated with a previous request. If the current request is received on a non-preferred communication band, and a previous request was received on a preferred communication band within a pre-determined time, the system determines whether the signal strength associated with the previous request is weaker than a pre-determined threshold signal strength level for the preferred communication band. If so, the system responds to the current request. Otherwise, the system ignores the current request. If no recent request on the preferred communication band is received, and the signal strength associated with the current request is weaker than a pre-determined threshold signal strength level for the non-preferred communication band, the system responds to the current request on the non-preferred communication band. Otherwise, the system ignores the current request.

  • Publication number: 20120278440
    Abstract: The present disclosure describes a system for dynamic transaction-persistent server load balancing. The disclosed system receives a client request associated with a new transaction. In response to receiving the client request, the system dynamically infers relative capacities of a plurality of servers coupled to the device in a network. In particular, the system maintains a set of variables corresponding to the servers. Each variable indicates a number of outstanding requests transmitted from the device to a respective server. The system infers relative server capacities and transmission latencies between the device and the servers based on a comparison of current values of the variables. The system identifies and selects a server associated with high capacity or low transmission latency between the device and the server relative to one or more other servers, and transmits an outstanding request corresponding to the client request from the new transaction to the identified server.

  • Publication number: 20120243456
    Abstract: Mobility of firewall rules for clients moving among bridge AP nodes in a wireless network. APs operate in bridge mode. A wireless client C is associated with a first AP. As part of that association, the first AP establishes and maintains personal firewall rules and state for client C. When wireless client C associates with a second AP in the L2 domain, the second AP sends session request to other APs. This may be in the form of a multicast message. Optionally, the second AP may send a unicast message to the first AP indicating that client C has associated with the second AP. APs receiving the multicast session request message for client C check their tables to see if they have stored firewall or other state for client C. APs having storied firewall or other state for client C send session response messages to the second AP containing stored firewall sessions and other state for client C. When the second AP receives a session response, it sends an acknowledgement to the AP which sent the response.
