Patent number: 9918248Abstract: Service continuity when a user equipment (UE) employing local breakout mechanisms at a femto access point (FAP) for a communication session and moves out of the femto coverage area is disclosed. In particular, a network change detection component can be employed to detect when the UE, attached to the FAP, changes its connection from the femto network to the macro network. Further, an active communication session can exist between the UE and a device/service/application on a local Area network (LAN) connected to a FAP, and/or the Internet, which utilizes local breakout at the FAP. When the UE moves out of the femto network, a context management component can be employed to seamlessly resume the communication session, via the macro network.Type: GrantFiled: July 20, 2015Date of Patent: March 13, 2018Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., AT&T MOBILITY II LLCInventors: Cheng P.

Patent number: 9843519Abstract: Local breakout mechanisms can be performed by a femto access point (FAP) to facilitate efficient utilization of backhaul and/or macro networks. In particular, a slave Gateway GPRS Support Node (GGSN) can be integrated within the FAP to directly route the incoming traffic from a user equipment (UE) at the FAP. In one example, Internet bound traffic can be directly routed to the Internet, without employing macro network resources. Further, the system can avoid hairpinning by routing traffic between the UE and a home Local Area Network (LAN) by a anchoring a call or a session in the slave GGSN and facilitate integration of UEs with home applications by employing a UE Digital Home Agent. In addition, the FAP can perform UE-to-UE CS media breakout to facilitate communication between UEs attached to the FAP, without routing the traffic through the core macro network.Type: GrantFiled: April 5, 2017Date of Patent: December 12, 2017Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., AT&T MOBILITY II LLCInventors: Cheng P.

Patent number: 7830861Abstract: In order to provide a single common cost-efficient architecture for real time communication services for audio, video, and data over internet protocol, a voice over internet protocol (VoIP) system and architecture is provided by placing border elements (BEs) at the interface boundaries between the access network the user devices use and the VoIP infrastructure. The BEs use SIP protocol as the access call control protocol over any access networking technologies, for example, IP, Ethernet, ATM, and FR, and provides all services transparently to the end users that use SIP-enabled devices. To enable a scalable system, the SIP BEs are decomposed into separate communicating entities that make the SIP BE scalable and provide new capabilities not previously available by a self-contained SIP BE.Type: GrantFiled: March 1, 2004Date of Patent: November 9, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Siroos K.

Publication number: 20100130170Abstract: A system and methodology that provides management services during local breakout at a femto access point (FAP) is provided. In particular, the FAP facilitates policy management and employs a policy component to perform an analysis and enforce a set of policies for dynamically selecting an optimal route for traffic received at the FAP based on a decision-making process. Typically, the set of policies can specify different routes based on various factors, such as, but not limited to, type of traffic, current and/or future network resource availability, current time, day and/or date, location of the FAP, location of a UE sending/receiving the traffic, a lowest cost route, and/or route based on cost-benefit, etc. Further, a monitoring component is employed to observe the route employed by that traffic, which can be utilized by various services, such as, billing, Quality of Service, security management, address management, failure management and/or provisioning.Type: ApplicationFiled: November 20, 2009Publication date: May 27, 2010Inventors: Cheng P.
