The Evolved Packet Core portfolio includes SGSN/MME* and Mobile Packet Gateway – software upgrades of the existing SGSN and GGSN. PDF | SGSN and GGSN are the two core network elements of the general packet radio service which enables Ahmad Ali Habeeb at Ericsson. GGSN communicates to SGSN and when it receives data variables. It was designed by Ericsson to support fault-tolerant and distributed applications.

One skilled in the art would understand that the principles and features described above in relation to the FORCES and OpenFlow protocols can also be implemented in other similar control protocols.

A gateway location register GLR can be used to optimize the subscriber handling between network boundaries. GTP-U control packets that are originated by the switch are generated on the software control plane and are routed by the control plane.

Mobile network operators cannot set up multiple peering points and PoPs between neighboring operators within the aggregation network. For example, one flow table can perform QoS processing while a second flow table does routing. EP EPB1 en It is the user that decides whether he is satisfied with the provided QoS or not.

The OpenFlow control plane can in principle use the same physical control plane paths as the GTP-C and other sgzn network signaling.

Each 3G PC instance is in a VPC A,B that isolates the mobile operator’s traffic from other tenants in the cloud computing facility of the data center.

A layer of software called a hypervisor sits between the operating system and the hardware. Restarting the control plane module ensures a level of load sharing for a pool of control plane modules.


So, for instance, a Google query from a smartphone would ericson routed via the SGSN to the GGSN and sent on as a query to the Internet search engine, then the process would be reversed for the reply to the phone user. The split between the control and data plane parts of the 3G PC can be used together with virtual private cloud VPC technology to implement multiple PoPs within a single 3G PC, provide GTP flow-specific routing for specialized applications, and run multiple operator networks from a single cloud computing facility.

One skilled in the art would understand that the principles and features described above in relation to the cloud computing system can also be implemented in other configurations such as single servers or distributed server systems. The core network also contains databases and network management gsn.

However, when demand is high for the services of the home subscriber server HSSthe server pool dedicated to the HSS servers will be heavily utilized, but the server pool for the SGSN is underutilized.

To rate this item, click on a rating below. The primary functions of the core network with respect to mobile wireless networking are mobility management and QoS. The GTP ericssno flags field sricsson also ericsaon wildcarded, this can be partially matched by combining the following bitmasks: Actions allow manipulating of tag stacks by pushing and popping labels. The mask is combined with the message type and header field of the packet using logical AND; the result becomes the value of the match.

A GTP-extended Openflow switch can also accomplish GTP routing without performing the gateway functions of encapsulation and decapsulation. The GTP tunnel establishes the route of the subscriber session across the core network of the 3G PC network to a peering point, the Internet or similar endpoint. An OpenFlow mobile gateway can be used to support GTP encapsulation and decapsulation with virtual ports.

The type can be been randomly generated so as not to interfere with other extended types. When additional signaling demands ericson that extra capacity, then a new SGSN instance is instantiated in the server pool.

The managed services cloud computing facility runs separate instances of the 3G PC control plane for every mobile operator with which the managed services company has a contract.

The subscriber session and associated GTP tunnel are deleted when the associated application on the user equipment or egsn application on the other user equipment or the server application on the other end of the subscriber session terminate the connection. Similar principles and features to those described above can be implemented in single server systems, ericdson server systems and similar computing environments.

Implementing the control plane of an 3G PC in a cloud computing facility and the data plane of the 3G PC using a set of OpenFlow switches, as well as managing communication between the control plane and the dataplane using the OpenFlow protocol e. The main function of the core network is to provide switching, routing and transit for user traffic from the user equipment The VM is created on a hypervisor managed server with in the VPC for the enterprise requesting the new service instance step 1.

Software defined network-based load balancing for physical and virtual networks. Communication system and method for providing access to the external network to the wireless terminal. Network node and method for handling a traffic flow related to a local service cloud. GTP virtual ports are configured from the OpenFlow controller using a configuration protocol.
