Patent number: 9930075Abstract: A method for controlling media communication session between a user and a receiving equipment via a core network is disclosed. The method includes checking a database to retrieve policy rules applicable to the user. The method also includes identifying the establishment of a default bearer for the user and analyzing all traffic packets originating from or directed to the user. The method further includes checking the establishment of a requested media communication session and determining the type of media session requested and established, and the IP addresses and ports of the user and the receiving equipment. The method also includes creating a dedicated bearer between the IP addresses and related ports of the already established media session, on the basis of the information retrievable from the packets belonging to the established media session and the database.Type: GrantFiled: June 27, 2014Date of Patent: March 27, 2018Assignee: ATHONET S.R.L.Inventors: Gianluca Verin, Karim El Malki

Patent number: 7353027Abstract: In a system and method for handing off a mobile node in a seamless manner in a wireless access network, procedures are implemented for allowing the mobile node to synchronize the handoff with a base node (e.g., a home agent) and a correspondent node. In this way, a seamless handoff may be achieved, since few or no data packets sent between the base node or the correspondent node and the mobile node are lost. The procedures are supported by both Mobile IPv4 and Mobile IPv6 as well as Hierarchical Mobile IPv4 and Hierarchical Mobile IPv6.Type: GrantFiled: October 18, 2001Date of Patent: April 1, 2008Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Georgios Karagiannis, Geert Heijenk, Karim El Malki, Hesham Soliman

Patent number: 6947401Abstract: Methods and apparatus for providing a hierarchical mobility management function for routing packets to mobile nodes are provided. The hierarchical mobility management function may be placed anywhere within the network and provide efficient use of IPv6 addresses. A node implementing the hierarchical mobility management function receives packets intended for the mobile node and routes the packets to the mobile node's current address. Load sharing of packets intended for a mobile node may be implemented across several access routers. Additional, bi-casting of packets is provided to allow for seamless handoff of the mobile node as it switches from one access router to another access router.Type: GrantFiled: February 16, 2001Date of Patent: September 20, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Karim El-Malki, Hesham Soliman

Patent number: 6044068Abstract: An echo cancellation method and apparatus (20) determines whether a window W(m) of samples on an incoming communications path (30) contains silence, the window W(m) including the sample obtained at time t(m) and prior samples. If the window W(m) contains silence, coefficients of an adaptive filter (52) of the echo canceller (20) are set to silence detection values prior to receipt of a sample at time t(m+1). If the window W(m) does not contain silence and there is no double-talk, the sample obtained at time t(m) is used to update coefficients of the adaptive filter; the adaptive filter as updated generates an echo estimate after a sample is obtained at time t(m+1); and, the echo estimate is used to modify a signal on an outgoing communications path (32).Type: GrantFiled: October 1, 1996Date of Patent: March 28, 2000Assignee: Telefonaktiebolaget LM EricssonInventor: Karim El Malki

Patent number: 5920548Abstract: An echo cancellation apparatus (20) and method involves an operation AEPR for analyzing echo path response and thereafter an operation CR for configuring an adaptive FIR filter (52). The configuration of the adaptive filter (52) advantageously results in only a range of filter taps and coefficients between two specified tap endpoints being involved in filter multiplication, addition, and storage during the echo cancellation operation.Type: GrantFiled: October 1, 1996Date of Patent: July 6, 1999Assignee: Telefonaktiebolaget L M EricssonInventor: Karim El Malki
