Patent number: 9008056Abstract: Remote access for a terminal to a first network via a second network is managed; the first network being linked to the second network via a network apparatus. At the level of the network apparatus, there is received, from the terminal via the second network, a request for remote access to the first network indicating access information comprising a first parameter corresponding to a physical address of the terminal and a second parameter corresponding to a secret key of the gateway. The network apparatus thereafter decides whether the terminal is authorized to remotely access the first network on the basis of said access information. This network apparatus subsequently emits, bound for the terminal via the second network, a message indicating whether the terminal is authorized to remotely access the first network.Type: GrantFiled: June 23, 2009Date of Patent: April 14, 2015Assignee: OrangeInventors: Erwan Le Ber, Philippe Hemon

Patent number: 9001669Abstract: In one embodiment, in response to a trigger condition being detected at a particular location in a primary directed acyclic graph (DAG) in a computer network, a particular node in the primary DAG at the particular location may be determined to act as a remote stitched (RS)-DAG root for an RS-DAG at the particular location. The determined RS-DAG root may then be instructed to initiate the RS-DAG, the instructing indicating one or more properties for the RS-DAG that are based on the trigger condition and that are different from properties of the primary DAG. In another embodiment, a particular node receives instructions to initiate an RS-DAG as its RS-DAG root, initiates the RS-DAG, and relays messages of the RS-DAG with a primary root of the primary DAG.Type: GrantFiled: March 8, 2011Date of Patent: April 7, 2015Assignee: Cisco Technology, Inc.Inventors: Jean-Philippe Vasseur, Shmuel Shaffer, Sandeep Jay Shetty

Patent number: 8995466Abstract: A base station uses a common link layer controller for multiple physical attachment points to facilitate concurrent wireless connections between different sector physical attachment points and a wireless terminal using the same link layer link. A wireless terminal maintains multiple simultaneous wireless connections for the same link layer link. A packet of user data is fragmented into a plurality of grouping of MAC frames, thus a packet portion can be communicated over a connection. A single packet is sometimes communicated with different portions conveyed over different wireless connections. Automatic repeat request, using the common link layer controller, allows for retransmission of a packet portion over a different connection than it was initially transmitted over. A wireless terminal sends connection request messages including lists of link layer identifiers associated with the wireless terminal. A base station responds with an indication of whether logical link state was already present.Type: GrantFiled: December 22, 2005Date of Patent: March 31, 2015Assignee: QUALCOMM IncorporatedInventors: Pablo Anigstein, Murari Srinivasan, Sathyadev Venkata Uppala, Rakesh Champalal Dugad, Arnab Das, Vladimir Parizhsky, Rajiv Laroia

Patent number: 8885584Abstract: An apparatus and method of determining an allocation of data across multiple data communications networks. A first portion of a data set is received through a first data communications network. A second portion, that is different from the first portion, of the data set is received through a second data communications network that uses a different data communications protocol than the first data communications network. A respective characteristic of the first data communications network and the second data communication network are determined at a receiver. In response to determining these respective characteristics and based upon the respective characteristics, an allocation of data between the first data communications network and the second communications network is determined such that the allocation satisfies at least one data transfer performance requirement associated with the data set.
