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.

Gateway GPRS Support Node

The core network is used for transmitting Internet Protocol IP packets. The cloud computing system of claim 11wherein the controller is configured to remove configuration of the at least one switch in the route of the GTP tunnel, via the control plane protocol, to end forwarding of packets of the subscriber session according to the GTP tunnel.

The control plane entities and the OpenFlow controller are packaged as VMs. The subscriber session resources are then reclaimed by deleting the subscriber session and the GTP tunnel. If necessary, the message specifies actions and instructions, as described above, to establish a new flow route for the GTP tunnel that encapsulates and decapsulates the packets through the appropriate virtual port.

The actions that are defined by the specification of OpenFlow 1.

M Year of fee payment: A check is made to determine the next table to process, which can be the next table sequentially or one specified by an action of a matching rule Block The cloud computing system of claim 12wherein the controller is configured to configure a switch in a new route of the GTP tunnel, via the control plane protocol, to forward packets of the subscriber session according to the GTP tunnel.

To rate this item, click on a rating below. Actions allow manipulating of tag stacks by pushing and popping labels. An action allows ssgsn writing of data to a metadata register, which is carried along in the packet processing pipeline like the packet header.

The cloud manager also provides reliability and failover by restarting a VM for a particular ericssoj plane entity or function if any of the 3G PC control plane entities should crash.

The method of claim ericssofurther comprising the step of removing configuration at the least one switch in the route of the GTP tunnel, via the control plane protocol, to end forwarding of packets of the subscriber session according to the GTP tunnel. In further embodiments, a subset of the control plane entities can be virtualized or executed in a cloud computing system while another subset of the control plane entities can be executed in a server, distributed server system or similar system.


The techniques shown in the figures can be implemented using code and data stored and executed on one or more electronic devices e. A cloud computing system for managing implementation of a general packet radio service GPRS tunnel protocol GTP in a packet core PC of a third generation 3G network having a split architecture where a control plane of the PC of the 3G network is in the cloud computing system, the control plane to communicate with a data ggsn of the PC through a control plane protocol, the data plane implemented in a plurality of network elements of the 3G network, the cloud computing system comprising: The embodiments of the present invention provide a method and system for avoiding the disadvantages of the prior art.

Communication system, serving gateway, communication method therefor, and base station. If you found this interesting or useful, please use the links to the services below to share it with other readers. Notifying a controller of a change to a packet forwarding configuration of a network element over a communication channel.

The long dash and dotted lines and arrows shows a example of a UE that is obtaining content from an external source. The operations of the flow diagrams will be described with reference to the exemplary embodiments of FIGS.

Apparatus, and associated method, for multicasting data in a wgsn communications system. After each flow table match, the actions are accumulated into an action set. So, for instance, a Google query from a smartphone would be 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.

These messages can be identified by the following message codes:. GTP-U control packets that are originated by the switch are generated on the software control plane and are routed by the control plane. Thus, a method, system and apparatus for implementing a 3G PC in a cloud ericxson system has been described. The split ggdn 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.

Mapping virtual machines from a private network to a multi-tenant public datacenter. Services, applications and similar programs can be virtualized or executed as standard code. 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.


A received packet is compared against each gsn the flow tables Cloud computing systems can virtualize the network by incorporating a virtual switch into the hypervisor. ericssoh

However, it is understood that embodiments of the invention may be practiced without these specific details. EP EPB1 en The OpenFlow message programming the rule insertion also includes information on the values for the sequence number, N-PDU number, or the type and contents of the extension header, as well as the packet header ericeson designating the decapsulation gateway and bearer transport and the GTP TEID.

These principles and features can also be implemented using a non-virtualized environment including non-virtualized control plane entities that are executed in any combination of cloud computing systems, single servers, distributed server systems and similar systems.

The OpenFlow controller does not respond to the calling entity until all flow routing updates have been accomplished.

Agsn tunnels are deleted using the delete session request procedure. A cloud computing system can support ggsh single cloud or service or any number of discrete clouds or services. A modification process can be utilize to re-route a subscriber session across the 3G PC network to the same endpoints or to different endpoints.

In addition to forwarding the packet, the switch fast path makes the OpenFlow metadata field available to the slow path software. Details of this configuration are described in further detail herein below.

In this embodiment, there is an explicit provision for multiple flow tables The cloud manager monitors the central processor unit CPU utilization of the 3G PC control plane entities and the control plane traffic between the 3G PC control plane entities within the cloud. However, it should be understood that the operations of the flow diagrams can be performed by embodiments of the invention other than those discussed with reference to FIGS.

During this restart process the cloud manager can collect diagnostic data, save any core files of the failed 3G PC control plane entity, and inform the system administrators that a failure occurred. A VM is an operating system image packaged with some applications. These control plane entities can communicate with one another through local system or procedure calls, remote procedure calls sricsson similar mechanisms. Telecom Innovators Video Showcase.
