Abstract: An example method is provided in one example embodiment and includes establishing a mobility context associated with a user equipment that includes a designation of a first radio access network as a primary access network and a second radio access network as a secondary access network. The method further includes defining an initial value for a data count variable representative of a number of consecutive uplink packets associated with the user equipment received over the first radio access network. The method further includes receiving at least one first uplink packet associated with the user equipment from at least one of the first radio access network and the second radio access network, modifying a value of the data count variable when the first uplink packet is received over the second radio access network, setting the value of the data count variable to the initial value of the data count variable when the first uplink packet is received over the first radio access network, and modifying the mobility context if the value of the data count variable is equal to a predetermined value.

Abstract: A system may provide connectivity service in a multi-tenant network. A first node in the multi-tenant network can receive data packets, each of the data packets identifying one of a plurality of tenant devices. The first node can determine an Internet Protocol (IP) address associated with each of the data packets. The first node can determine a Virtual Local Area Network Identifier (VLAN ID) based on the IP address, the VLAN ID being a unique identifier of a respective one of the tenants. The first node can add the VLAN ID of a corresponding one of the tenants into a header of each of the data packets. The first node can transport the data packets to a second node in the multi-tenant network via a multi-tenant network tunnel protocol.

Abstract: The techniques described herein provide mechanism that allows a Vehicular Communication Systems (VCSs) server, e.g., a cluster server, or other network attached device to group or cluster a set of vehicles into a multicast group according to common mobility characteristics shared by the set of vehicles. For example, the set of vehicles may be in close proximity to each other and are traveling on the same road, or share a common destination. Information pertinent to the cluster, can be broadcast to the multicast group in lieu of traditional individual unicast messages that would typically be sent to each vehicle.

Abstract: Methods and systems for providing a dynamic and real time load factor that can be shared with other network elements is disclosed. The load factor can be used in determining the relative load among a set of network elements and in distributing new sessions requests as well as existing session on the set of network elements. The load factor can also be used for determining to which network element a user equipment is handed off. The dynamic load factor can also be shared amongst network elements to determine how the load is balanced among the network elements, such as a mobility management entity (MME).
