Patent number: 8699461Abstract: A method to provide an optimized intra-HeNB GW handover operation that reduces signaling to and from an LTE MME (Mobility Management Entity) function of the 3GPP E-UTRAN Evolved Packet core (EPC). In operation, an HeNB Gateway (GW) intercepts handover requests from a source HeNB to a target HeNB and processes these requests locally, with minimal interaction from the MME. Where possible, messaging to and from the MME is minimized and/or reduced, irrespective of the 3GPP requirement that the GW relay all handover-related messages to the MME.Type: GrantFiled: August 19, 2011Date of Patent: April 15, 2014Assignee: Hitachi, Ltd.Inventors: Haibo Qian, Michael Brown, Curtis Provost

Publication number: 20100290621Abstract: In a network that supports mobility of a mobile node, a tunnel between a first mobility node and a second mobility node is established in the network. The established tunnel is according to a tunneling protocol (e.g., Generic Routing Encapsulation tunneling protocol) that uses at least one key (208) for encapsulating data communicated through the tunnel. The symmetric or asymmetric key may be used for identifying a particular traffic flow in either the forward or the reverse direction between mobility nodes, e.g., when supporting mobility nodes that are using overlapping private IPv4 addressing. Signaling is communicated to provide mobility support of the mobile node according to a mobility protocol, where the mobility protocol is selected from among a Proxy Mobile Internet Protocol and Mobile IP version 6.Type: ApplicationFiled: March 12, 2008Publication date: November 18, 2010Applicant: NORTEL NETWORKS LIMITEDInventors: Ahmad Muhanna, Mohamed Khalil, Barnaba Barnowski, Curtis Provost

Patent number: 7702311Abstract: A serving GPRS node (SGSN) is made content aware by passing content based rate information in the GPRS tunnel protocol (GTP) header. The SGSN uses the PDP context request to inform a GPRS support node (GGSN) that it is content aware and can process the content based rate information. In one embodiment, the rate information is passed in a GTP extension header. A new GTP header type tells the SGSN that rate information is present in the GTP header content field. In an alternate embodiment, the rate information is passed in a fourth octet of a four octet tunnel endpoint identifier (TEID).Type: GrantFiled: June 30, 2003Date of Patent: April 20, 2010Assignee: Nortel Networks LimitedInventors: Jerry Mizell, David J. Lauson, Curtis Provost

Patent number: 7027825Abstract: A system for delivering SMS messages to a mobile terminal includes an apparatus and method that deliver the SMS messages either using legacy SMS message formats or data packet formats. Additionally, a connection is created between a message center and a gateway GPRS support node wherein SMS messages may be transmitted to the gateway GPRS support node in a data packet format. To provide this capability, the gateway GPRS support node includes a unique port address for receiving SMS messages and circuitry for processing SMS messages received in a data packet format. A serving GPRS support node is formed to include circuitry for determining whether to transmit the SMS message to the mobile terminal in a data packet format or in a legacy SMS message format.Type: GrantFiled: December 20, 2000Date of Patent: April 11, 2006Assignee: Nortel Networks, LimitedInventors: Jerry Mizell, Curtis Provost, David J.
