Systems, methods and computer software are disclosed for providing multi-User Equipment (UE) and multi-message support in tunnel management messages. In one embodiment, a method is disclosed, comprising: determining, for a first node and a second node using GPRS Tunneling Protocol (GTP) tunneling support for UE management, if the first node and the second node support multi-UE messaging; when the first node and the second node support multi-UE messaging, then switching to multi-UE multi-messaging mode wherein a chain of messages are formed; and when at least one of the first node and second node do not support multi-UE messaging, then using conventional tunnel management messaging.

Multi-UE and multi-message support in tunnel management messages

Systems, methods and computer software are disclosed for providing core High Availability (HA) for a wireless network. In one embodiment, a method is disclosed, comprising: providing a first node, a second node and a third node; allocating a set of locally generated Tunnel Endpoint Identifiers (TEIDs) for UEs anchored on the second node; detecting, by a first node, a second node having a connectivity issue; and migrating a User Equipment (UE) connected to the second node to a third node which is accessible; using the set of locally generated TEIDs to identify the UE migration.

Locally-generated TEIDs for core high availability

Systems, methods and computer software are disclosed for providing network address translation with a tunnel identifier (TEID) in a cellular network. A HetNet Gateway (HNG) allocates at least a portion of a unique TEID for a user equipment (UE). The HNG receives a packet having a source field in the packet header including an Internet Protocol (IP) address. The HNG replaces the IP address in a source field of the packet header of the packet with the unique TEID for the UE and forwards the packet using the unique TEID to a packet gateway (PGW).

Network address translation with TEID

Systems, methods and computer software are disclosed for supporting idle mode signaling reduction (ISR) core offload. In one embodiment a method includes providing an eNodeB co-located with a NodeB, and a User Equipment (UE) with ISR enabled; activating ISR when the UE goes idle and is switching between different Radio Access Technologies (RATs), and wherein UE connections are maintained with a Serving GPRS Support Node (SGSN) and a Mobility Management Entity (MME).

Idle mode signaling reduction core offload

Method and system for transmitting same data by at least two different ports of a network device coupled to a computing device or to at least two different destinations coupled to a same port of the network device is provided. The computing device sends a single command for sending the same data to the network device. The network device obtains the same data from the computing device via one direct memory access (DMA) operation; and then sends only one notification for transmitting the same data via at least two different ports or to two different destinations via the same port.
