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.

The virtual port simply removes the GTP tunnel header and forwards the enclosed user data plane packet out the bound physical port.

The cloud zgsn can initialize a new control plane module or an instance of such a control plane module as a separate virtual machine Block GTP-C—a control plane protocol that supports establishment of tunnels for mobility management and bearers for QoS management that matches wired backhaul and packet core QoS to ericsson link QoS; and GTP-U—a data plane protocol used for implementing tunnels between network elements that act as routers.

The Many Faces of Digital Transformation.

The cloud manager then monitors the resource utilization of each control plane module as well as the amount and type of control plane traffic handled by each control plane module Block Restarting the control plane module ensures a level of load sharing for ghsn pool of control plane modules. Similarly, the control plane entities can be executed as standard software code and modules without virtualization or similar systems.

If the packet has an IP header Blockthen there are a series of steps for processing the IP header Blocks – The secure channel can be provided by any type of network including a local area network LAN or a wide area network WANsuch as the Internet.

Absent the inclusion of an action in the set to execute all accumulated ericzson immediately, the actions are executed at the end of the packet processing pipeline.

In one embodiment, the system implements non-gateway GTP routing. In the embodiment, shown in FIG.

These functions are not typically provided in a fixed broadband network, but they are crucial for wireless networks. Method and cloud computing system for implementing a 3g packet core in a cloud computer with openflow data and control planes.

However, it should be understood that the operations of the ggs diagrams can be performed by embodiments of the invention other than those discussed with reference to FIGS. One skilled in the art would understand that the principles and features described above in relation to the FORCES and Egicsson protocols can also be implemented in other similar control protocols. In one embodiment, a group table can be supported in conjunction with the OpenFlow 1. Post a Comment Read 0. System and method for coordinated remote control of network radio nodes and core network elements.

The cloud computing system can be a private or public system. The GTP tunnel is an established route of the subscriber session across the core network of the 3G PC network to a peering point, the Internet or similar endpoint.

Communication system, serving gateway, communication method therefor, and base station. The switch also writes an entry in the TEID hash table containing the tunnel header fields for the packet.

Methods and apparatus to configure virtual private mobile networks with virtual private networks. The configuration command ericsso be run in ericssson transaction so that, when the results of the action ericssson reported back to the controller, either a GTP-U fast path virtual port for the requested datapath has been instantiated or an error has returned indicating why the request could not be honored.

ericswon The long dash and dotted lines and arrows shows a example of a UE that is obtaining content from an external source. The cloud manager also provides reliability and failover by restarting a VM for a particular control plane entity or function if any of the 3G PC control plane entities should crash.

The control plane entities can communicate with the data plane through the use of the OpenFlow protocol as described herein above or through other control protocols as described herein below.

The transcoding application reformats the content so that it will fit on the UE’s screen. The cloud manager or cloud operating system is a software program that can schedule execution to allow an in-service upgrade of hardware and software without impacting ongoing service provisioning to the VMs and their applications in the cloud computing system.

If the cloud manager detects a threshold level of resource utilization or traffic load for any one of the plurality of control plane modules being monitored Blockthe cloud manager can takes steps to automatically respond to this scenario. If you found this interesting or useful, please use the links to the ericseon below to share it with other readers.

The rest of the structure contains the GTP extension messages. In one embodiment, the process begins with the initialization of the control plane modules of the 3G Ericsso within the OpenFlow controller in the cloud computing system Block The architecture of the core ericszon can change when new services and features are introduced.


Tunnel endpoint device, communication device, communication system, communication method and program. The GTP header flags field can also be wildcarded, this can be partially matched by combining the following bitmasks: CA CAA1 en The method of claim 1further comprising the steps of: The standard 3G PC architecture assumes a standard routed IP network for transport on top of which the mobile network entities and protocols are implemented.

The core network also contains databases and network management functions. The cloud computing system of claim 8wherein the controller is configured to receive a request to modify the GTP tunnel in the PC of the 3G network between the SGSN and GGSN for the subscriber session, the controller is configured to modify configuration of the switch implementing the data plane of the SGSN, via the control plane protocol, to encapsulate and decapsulate packets of the subscriber session and to modify the first GTP tunnel endpoint, and the controller is configured to modify configuration of the switch implementing the data plane of the GGSN, via the control plane protocol, to encapsulate and decapsulate the packets of the subscriber session and to modify the second GTP tunnel endpoint.

This causes the packet to be forwarded ericsspn the gateway switch’s local GTP-U control port for processing by the local software control plane.

This implementation technology is favorable for scalable management of the control plane entities within the cloud, since it allows execution of the control plane entities and the controller to be managed separately according to demand.

It also monitors the control plane traffic between the end user devices UEs and NodeBswhich do not have control plane entities in the cloud computing systemand the 3G PC control plane entities In addition, peering points are usually without cost to operators as long as the service level agreements SLA s are observed.

There are four different types of groups: These are inserted into the encapsulation virtual port. EP EPB1 en In one embodiment, the system implements handling of GTP-U control packets.
