| 20080267128 | Handover from E-UTRAN to UTRAN/GERAN CS - The present invention relates to a method for a handover of a UE (User Equipment) currently engaged in a voice call. More particularly, the invention relates to a handover from 1) a packet based radio where Voice Service is provided via VoIP over the radio and is controlled via Session Initiation Protocol (SIP) based signalling (e.g. LTE, E-UTRAN or WIMAX radio) to 2) a radio access network where Voice Service can be only provided via circuit switched (CS) domain (a visited mobile switching centre (VMSC) is needed) such as legacy 3GPP UMTS Terrestrial Radio Access Network (UTRAN)/GSM/Edge Radio Access Network (GERAN) coverage. A MSC-S entity acting as a Packet Core Control Node on a Packet Switched (PS) network and as an Anchor Visited Mobile Switching Centre (VMSC) for a handover to a Circuit Switched (CS) network on the CS domain side is proposed, the MSC-S preparing a new path with a remote UE-B and a CS domain handover towards a target legacy radio coverage before requesting a UE-A to execute the handover. | 10-30-2008 |
| 20080311913 | METHOD FOR MOBILITY MANAGEMENT IN A SYSTEM ARCHITECTURE SUPPORTING MOBILITY BETWEEN DIFFERENT ACCESS SYSTEMS - One object of the present invention is a method for Mobility Management MM in a system architecture supporting mobility between different access systems having separate Core Network CN-level MM entities while using common MM Area, said method comprising a step of:

| 20090245123 | METHOD FOR SIMULTANEOUSLY ACCESSING CIRCUIT SERVICES AND PACKET SERVICES IN A CELLULAR MOBILE RADIO SYSTEM - A method for simultaneous access to circuit services and packet services in a cellular mobile radio system comprising second generation cells and third generation cells, in which method, if a packet or a circuit connection is required by a terminal already having a circuit or a packet connection set up in a second generation cell, the method determines whether a change of cell to a third generation cell is possible and, if so, effects said change of cell in order to allow said circuit and packet connections simultaneously in a third generation cell. | 10-01-2009 |
| 20090310622 | Minimal GAN RTP packet length via multi-level header compression - The present invention involves a method for IP header compression for Real-Time Transport Protocol (RTP) packets that includes header compression for the outer IP layer that carries IPsec ESP tunnel traffic. The preferred embodiment of the invention involves a method of producing minimal VoIP packet size in a GAN user plane by defining an ESP/UDP/IP profile for ROHC; using the ESP/UDP/IP profile to compress the outer layers carrying IPsec ESP tunnel traffic in the GAN user plane; and using a ROHC RTP/UDP/IP profile between IPsec ESP tunnel endpoints for additional compression. | 12-17-2009 |
| 20110158121 | EXPLICIT INDICATION OF BEARERS SUBJECT TO VOICE CALL CONTINUITY - A method, user equipment and a network entity are disclosed. The method comprises the steps of: determining which of a plurality of packet bearers carry voice media components for handover between a packet-switched network and a circuit-switched network to ensure voice call continuity; and notifying an entity that will said enforce voice call continuity for which of said plurality of packet bearers carry said voice media components. | 06-30-2011 |
| 20120023178 | MESSAGE TRANSMISSION - A method of transmitting a message to user equipment within a telecommunications network, a controller operable to transmit a message to user equipment within a telecommunications network, a base station and a computer program product are disclosed. The method comprises the steps of: receiving a message having message content to be transmitted to user equipment within a predefined geographical area of the telecommunications network; identifying at least one multicast IP address designated as being associated with base stations providing telecommunications coverage with user equipment within the predefined geographical area; and transmitting the message content within at least one multicast message, each multicast message using a corresponding one of the at least one multicast IP address, over an IP network to base stations providing telecommunications coverage within the predetermined geographical area for onward transmission to user equipment. In this way, each base station identified by the multicast IP address will simultaneously receive the message, rather than each individual base station needing to have its own dedicated message sent to each base station sequentially. This not only significantly speeds the time taken for identified base stations to receive the message, it also reduces the amount of traffic required since the message is transmitted in a multicast manner. Furthermore, only those base stations which are associated with the multicast IP address will act on the message, all other base stations may ignore it. This helps to ensure that the message is only relayed to user equipment in a particular geographical region, rather than being delivered to all user equipment supported by all base stations associated with a particular controller. | 01-26-2012 |
