20080285495 | Systems and Methods for Communicating to a Disassociated Station in a Protected Network - Stations in standby mode in a wireless local area network (WLAN) become disassociated with their access point. In the event traffic is intended for the station in standby mode, a wakeup message needs to be communicated to the station. Typically, a wakeup message could be broadcast on a broadcast or multicast address, and when the station checks for broadcasts, the station can determine whether it needs to wake up. However, in a protected network, a disassociated station cannot decrypt messages from the access point without reassociating. However, the cost of reassociating in time and power can be significant, so reassociating should not be performed unless the station needs to wake up, leading to a vicious cycle as the station does not know it must wake up unless it can decrypt the message. To address this issue, in one embodiment the access points do not encrypt messages on a select multicast address, whereby messages such as wakeup message can be transmitted. In another embodiment, the messages are still encrypted. However, the identification of which station must wake up is encoded as the length of the encrypted payload. These methods allow a general message of communicating to disassociated stations in a protected WLAN environment. | 2008-11-20 |

20080285541 | Intelligent computer network routing using logically centralized, physically distributed servers distinct form network routers - A route control architecture allows a network operator to flexibly control routing between the traffic ingresses and egresses in a computer network, without modifying existing routers. An intelligent route service control point (IRSCP) replaces distributed BGP decision processes of conventional network routers with a route computation that is flexible and logically centralized but physically distributed. One embodiment supplements the traditional BGP decision process with a ranking decision process that allows route-control applications to explicitly rank traffic egresses on a per-destination, per-router basis. A straightforward set of correctness requirements prevents routing anomalies in implementations that are scalable and fault-tolerant. | 2008-11-20 |
20080285542 | LOCATION BASED PRESENCE GROUPS - A presence system creates location based presence groups for presentities based on the current geographical location of the presentities. The presence system calculates respective distances between the presentities and forms respective location based presence groups for the presentities by including within each location based presence group those presentities whose calculated distance from the respective presentity is less than a configurable proximity metric. Each presentity is then provided with the presence information of all of the presentities within their location based presence group. | 2008-11-20 |
20080285543 | METHODS AND APPARATUS TO MANAGE INTERNET PROTCOL (IP) MULTIMEDIA SUBSYSTEM (IMS) NETWORK CAPACITY - Methods and apparatus to manage Internet Protocol (IP) Multimedia Subsystem (IMS) network capacity are disclosed. An example method comprises identifying a terminating voice over Internet protocol (VoIP) call server associated with a called device, and returning a call rejection indicator when the terminating VoIP call server is in a first condition, the call rejection indicator returned without a call initiation request message sent to the terminating VoIP call server. | 2008-11-20 |
