A network node adapted to forward incoming data packets, the network node including a tag identifying unit, adapted to identify a tag of an incoming data packet as a replicate tag; a tag look-up module, adapted to retrieve from a tag table a number of replications and destinations for the replicate tag; a replicating engine, configured to replicate the incoming data packet according to the number of replications, thereby generating replicated data packets; and a forwarding unit, adapted to forward the replicated data packets to the destinations.

Network node for network based multicast replication

A Policy Enforcement Function such as PCEF or TDF is configured to receive from a Policy Controller such as PCRF, over an interface such as Gx or Sd interface, a command related to a User Equipment UE, the command referring to a Sponsoring Context Identifier, Sponsoring Context ID, the Sponsoring Context ID serving as an identifier of a Sponsoring Context to be applied to application-related data traffic to be sponsored for the UE, the Sponsoring Context providing a list of data flows to be sponsored.

Dynamic provision of application related sponsored data connectivity

The disclosure relates generally to supporting bonded services at non-anchor nodes. A non-anchor gateway device is configured to support service bonding for a user device and communication with an anchor node of the user device. The non-anchor gateway device is configured to associated a set of user device data plane connections of the user device to form a bonded session for the user device where the set of user device data plane sessions includes a first user device data plane connection associated with a first access network and a second user device data plane connection associated with a second access network. The non-anchor gateway device is configured to map user device traffic of the user device between the user device data plane connections of the bonded session and a user device data plane session between the gateway device and the anchor node for the user device.

Providing bonded services at a non-anchor node

This disclosure relates to supporting handling of state information for a stateful network function of a communication network. The network function of the communication network is provided by a network function environment including a set of network function instances configured to provide the network function, a scheduler configured to receive messages of subscribers of the communication network and to distribute the messages to the network function instances for processing by the network functions instances in accordance with the network function, and a state information storage device configured to store state information of the subscribers. The network function instances are configured to temporarily store state information of the subscribers locally at the network function instances while subscribers are associated with the network function instances and to transfer state information of the subscribers to the state information storage device when the subscribers are no longer associated with the network function instances.

State-efficient network function support

Systems, methods, apparatus and mechanism for maintaining an existing UE control session attachment while changing bearers of a UE data session, such as migrating between UMTS and non-UMTS bearers terminating at a common gateway device.

System and method for seamless Wi-Fi to UMTS handover

Various embodiments provide a method and apparatus for processing incoming packets in an efficient manner. A service ID bitmap indicating available services associated with the user is established. The available services are grouped into service set. Common service set having common set of rules is determined. A user associated with common service set and incoming traffic is identified. The incoming traffic is processed according to the common set of rules indicated by the service ID bitmap. The efficient use of Ternary Content Addressable Memory (TCAM) results in faster search result, lower power consumption and chip footprint among others.

Method and apparatus for optimizing usage of ternary content addressable memory (TCAM)

A method and system for managing a backup service gateway (SGW) associated with a primary SGW, comprising periodically receiving from the primary SGW at least a portion of corresponding UE session state information, the received portion of session state information being sufficient to enable the secondary SGW to indicate to an inquiring management entity that all user sessions associated with a group of mobile devices supported by the primary SGW are in a live state; and in response to a failure of the primary SGW, assuming management of IP addresses and paths associated with the primary SGW and causing each UE supported by the failed primary SGW to reauthorize itself to the network.

System and method for session restoration at geo-redundant gateways

A method, system and apparatus for managing a backup service gateway (SGW) associated with a primary SGW, the backup SGW periodically receiving from the primary SGW at least a portion of corresponding UE session state information and in response to a failure of the primary SGW, assuming management of IP addresses and paths associated with the primary SGW, and in response to receiving control or data plane traffic associated with a UE, generating a Downlink Data Notification (DDN) message adapted to inform an MME that the UE is in a live state.

System and method for session resiliancy at geo-redundant gateways

A method, system and apparatus for reversion of UE sessions from a backup SGW or protect node to an operationally restored primary SGW or working node.

System and method for failover handling at geo-redundant gateways

Provided is a method for avoiding traffic duplication in a point to multi-point network, the method including monitoring a status of first interconnection links in a first data path from a source to a destination, the first data path including an ingress node, an egress node, and one or more intermediate nodes. The method further includes establishing a second data path if a link of the first interconnecting links is determined to be an inoperable link, the second data path including the ingress node, the egress node, at least one of the one or more intermediate nodes and second interconnecting links, the second interconnecting links including new interconnecting links and a subset of the first interconnecting links, the subset not including the inoperable link in the first interconnecting links.

Duplicate traffic avoidance in a point to multi-point network

A session bundle allocation capability enables dynamic allocation of bundles of sessions being handled by a network element to modules of the network element (e.g., modules such as processing modules configured to perform one or more of traffic processing, traffic switching, and like functions). A bundle of sessions may be allocated by associating a plurality of sessions to form thereby a bundle of sessions, and assigning the bundle of sessions to a processing module group including one or more processing modules configured for processing traffic for the sessions of the bundle of sessions. A bundle of sessions may have a bundle identifier associated therewith and may be migrated from a first processing module group to a second processing module group by changing a mapping of the bundle identifier from being associated with the first processing module group to being associated with the second processing module group.

Method and apparatus for allocating bundles of sessions in a network element

Providing a network service is disclosed. A data associated with the service is received. It is determined whether a local context associated with the service is in an active state with respect to the service. The data is redirected to another chassis, via an inter-chassis backup connection, if it is determined that the local context is not in an active state with respect to the service.
