Abstract:
A method for providing network services includes receiving a configuration request. The configuration request identifies a mobile node. The method also includes determining a location of the mobile node and selecting a directory agent based at least on the location of the mobile node. Additionally, the method includes transmitting to the mobile node a configuration response that identifies the directory agent.
Abstract:
Described is a system and method for scheduling delivery of traffic in a wireless network. The method comprises receiving packets addressed to a plurality of wireless computing units. A classification of each packet is determined. A transmission schedule is generated for the corresponding packet as a function of at least one of the classification and a priority request from at least one of the plurality of units. An indication message is generated as a function of the transmission schedule. A signal including the indication message is wirelessly transmitted.
Abstract:
Described is a system and method for management of a wireless environment. The system may includes a network management arrangement ("NMA"), a wireless mobile unit ("MU") and an access point ("AP). The AP receives a request for an association from the MU and transmits the request to the NMA. The NMA determines if the request is to be granted as a function of at least one of a plurality of predetermined factors which may include a data traffic load of the AP. If the request is not granted, the NMA determines a further AP to grant the request instead of the AP and instructs the AP to transmit a response to the MU including identification data of the further AP.
Abstract:
A method and system for managing presence information in a communication network (100) is provided. The method includes receiving (304) the presence information from at least one client of a set of clients at a protocol server (102). The presence information is associated with the at least one client of the set of clients is unique. Further, the method includes storing (306) the presence information of the at least one client of the set of clients in the protocol server. Moreover the method includes providing (308) the presence information of the at least one client of the set of clients to at least one client of a remaining set of clients by the protocol server. The remaining set of clients being the set of clients other than the at least one client of the set of clients.
Abstract:
Disclosed is a novel anion receptor and electrolytes containing the same. A novel anion receptor is a linear polyalkylene oxide compound having an amine substituted with electron withdrawing groups as (a) terminal group(s). When the anion receptor is added to the electrolyte, ionic conductivity and cation transference number of electrolytes are enhanced, thereby increasing the electrochemical stability of alkali metal batteries using the electrolytes.
Abstract:
The invention generally relates to a method for providing presence and instant messaging in a computer network (8). In particular, the invention is directed to a modified implementation of known wireless networking protocols (20) to provide instant messaging and presence services to mobile units (14). The instant messaging and presence services are provided within the framework of the native wireless networking protocol (20).
Abstract:
A method for executing end to end authentication in a network environment is provided that includes initiating a communications tunnel with a layer two tunnel protocol (L2TP) network server (LNS) and communicating an activate context request that includes an authentication protocol in a protocol configuration option (PCO) field, the activate context request being received by a gateway general packet radio service (GPRS) support node (GGSN) that initiates a link control protocol (LCP) negotiation with the LNS, the GGSN being operable to communicate an activate context response that may be received by the mobile terminal. An authentication response may be calculated by using a secret value and a challenge value which is provided by the GGSN, the authentication response being used to establish a communication session associated with the mobile terminal.
