Patent number: 9088884Abstract: A method for assigning a Voice Control Continuity (VCC) server to a User Equipment (UE) in a telecommunications network includes receiving an indication that the UE is registering with the network or attempting to make or receive an IMS communication session. A telephony network routing identifier and a VCC point code are assigned to the UE. The telephony network routing identifier is sent to the UE through the network and the VCC point code for the UE is sent through the network to the HLR to update the UE's profile data in the HLR.Type: GrantFiled: April 25, 2014Date of Patent: July 21, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Pierre Boulos

Patent number: 9014695Abstract: A Local Dialing Routing Application Server (LDR-AS) for resolving local dialing plans by a roaming mobile device in regard to a visiting network in which the mobile device is located with a Local Dialing Database (LDD) of the visiting network. The LDR-AS of a home network of the mobile device spatially distinct from the visiting network. Methods for resolving local dialing plans by a roaming mobile device with respect to a visiting network. A Local Dialing Database (LDD) for resolving local dialing plans by a roaming mobile device.Type: GrantFiled: September 18, 2012Date of Patent: April 21, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: David Brombal, Pierre Boulos

Patent number: 8811282Abstract: A system and method to provide call delivery to an Internet Protocol Multimedia Subsystem (IMS) network for a Mobile Directory Number (MDN) homed in a second generation (2G) wireless network, without requiring Wireless Intelligent Network (WIN) operations and associated Mobile Switching Center emulation (MSCe) translations for routing the call request. A Home Location Register (HLR) determines whether the subscriber has subscribed to the IMS services. The HLR-based subscriber profile is enhanced with new IMS-related subscriber information. Enhanced American National Standards Institute-41 (ANSI-41) Mobile Application Part (MAP) operations and a new ANSI-41 parameter allow the MSCe to re-route the call origination request from a Public Switched Telephone Network (PSTN) to an entry point for the IMS network based upon the new IMS-related subscriber information received from the HLR. A Domain Name Server (DNS) supports routing-related traffic distribution.Type: GrantFiled: June 29, 2011Date of Patent: August 19, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Pierre Boulos, Marvin Bienn, David Brombal

Patent number: 8738014Abstract: A VCC in a telecommunications network which also has an HLR, an S-CSCF, and an IMS mobile or UE. The VCC includes a network interface unit of the VCC which receives an indication that the mobile is registering with the network or attempting to make or receive an IMS communication session. The VCC includes a processing unit of the VCC which assigns a VDN or a telephony network routing identifier for the mobile, and assigns a VCC point code. The VDN is sent from the network interface unit through the network to the UE or the mobile. The VCC point code for the mobile or the UE is sent from the network interface through the network to the HLR to update the mobile's or UE's profile data in the HLR. A method for assigning a VCC to an IMS mobile or UE in a telecommunications network which also has an HLR and an S-CSCF.Type: GrantFiled: June 15, 2012Date of Patent: May 27, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventor: Pierre Boulos

Patent number: 7545766Abstract: The present invention supports an authentication protocol on a foreign agent to avoid rejecting re-registration request when congestion has delayed receipt at a mobile node of a foreign agent challenge code in a registration reply or agent advertisement message. Upon receipt of a re-registration request message containing a stale foreign agent challenge code, the identification code of the re-registration request message is compared to the identification code of the previous valid registration request message. If the identification code is greater than and not equal to the identification code in the previous valid request message, the foreign agent authenticates the message. The authenticated registration request message is processed to reset the lifetime so the communication session can continue.Type: GrantFiled: May 3, 2004Date of Patent: June 9, 2009Assignee: Nortel Networks LimitedInventors: Ahmad Muhanna, Pete Wenzel, Pierre Boulos

Patent number: 7167466Abstract: A method and apparatus for dynamically assigning a home agent to a mobile station for a mobile IP session. The method and apparatus allow the telecommunications network to assign the home agent that is best able to serve the mobile station. This is achieved by utilizing a predetermined IP address that indicates to the network components, such as the packet-switched data network, the home agent, the home authorization, authentication, and accounting server, and the like, that the mobile station is requesting a dynamically assigned home agent.Type: GrantFiled: November 20, 2001Date of Patent: January 23, 2007Assignee: Nortel Networks LimitedInventors: Kuntal Chowdhury, Serge Manning, Pierre Boulos

Publication number: 20030073439Abstract: A subscriber unit is assigned a primary home agent (HA) and at least one secondary HA. Upon an initial registration, the subscriber unit first attempts to access the primary HA. Should this operation fail the subscriber unit will attempt registration with one or more of the secondary HAs. The subscriber unit may rank order a plurality of secondary HAs for which it has been programmed. Such ranking may be based upon the generation of a random number and with the random number used to rank the plurality of secondary home agents. In another operation according to the present invention, a date or time of day is employed in rank ordering the plurality of secondary home agents.Type: ApplicationFiled: October 17, 2001Publication date: April 17, 2003Inventors: Peter W. Wenzel, Pierre Boulos, Steven J. Currin

Patent number: 6208634Abstract: Methods and apparatus for initiating calls between a mobile station and a base station in a wireless CDMA system wherein status request messages and status response messages are not required for the base station to determine alternate service options supported by the mobile stations are disclosed in accordance with the teachings of the present invention. The invention includes the mobile station transmitting an origination message to the base station wherein the origination message includes all service options supported by the mobile station. The invention also includes the situation where the base station sends a page message to the mobile station. The mobile station responds by determining whether the page message is intended therefor. If it is and if the mobile station is configured to receive mobile station terminated calls, the mobile station transmits a page response message to the base station which includes the service options supported by the mobile station.Type: GrantFiled: March 30, 1998Date of Patent: March 27, 2001Assignee: Nortel Networks LimitedInventors: Pierre Boulos, Ahmet Baltas
