A method and system for updating a mobile services database by caching some or all of relevant portions thereof, identifying and optionally prioritize those data objects that need updating, and periodically update only those data objects in response to a triggering event.

System and method for caching mobile services database objects

A method, system and apparatus for allocating a finite number of identifiers to a plurality of base stations in a wireless network and for iteratively processing respective ranges of identifiers to adapt identifier assignments in response to detected collision/confusion conditions.

Method and apparatus for dynamically allocating physical cell identifiers

A system, method and apparatus for policy-driven load balancing of MMEs and MME pools by migrating eNodeBs service responsibilities among MMEs and/or MME processing components or modules.

System and method for load balancing MMEs and MME pools

A method and apparatus for managing network resource consumption. In various embodiments, excessive resource consumption within a network such as a Long Term Evolution (LTE) wireless network attributed to one or more user devices (UDs) is constrained by adjusting a Policy Control and Charging (PCC) rule associated with a network element serving the UD such that the corresponding network resource consumption level is reduced.

Method and apparatus for managing mobile resource usage

A method and apparatus for analyzing mobile services delivery to provide a coherent, path-based awareness of the mobile services and the corresponding underlying transport elements supporting each service or path. In various embodiments, configuration information, status information and connections information associated with elements within a network such as a Long Term Evolution (LTE) wireless network are used to help infer or determine the connections between network elements to be managed.

Method and apparatus for analyzing mobile services delivery

A method and apparatus for rapidly discovering unknown or unmanaged portions of network using hints defining possible transport layer infrastructure topology and the like.

Method and apparatus for hint-based discovery of path supporting infrastructure

A method and apparatus for auditing mobile services delivery to provide a coherent, path-based awareness of the quality level of the mobile services and the corresponding underlying transport elements supporting each service or path. In various embodiments, service or connection audits triggered within a network such as a 4G Long Term Evolution (LTE) wireless network result in the execution of one or more test sequences adapted to provide service, connection or other information pertaining to the network or the supported mobile services.

Method and apparatus for auditing 4G mobility networks

Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving a selection of a configuration template and a second network node to serve a first network node, the configuration template including at least one template field; receiving at least one value for the at least one template field of the configuration template; configuring the first network node according to the configuration template and the at least one value; receiving, in the network management system, configured device information from the first network node; using the configured device information to identify at least one configuration operation to perform on the second network node to provide connectivity to the first network node; generating at least one configuration module for performing the at least one configuration operation; and applying the at least one configuration module to the second network node.

Rapid provisioning of network devices using automated configuration

A method and apparatus for determining a path supporting a mobile session to identify the underlying transport elements supporting the path. In various embodiments mobile session tracing is implemented within a network such as a Long Term Evolution (LTE) wireless network by determining elements in a path supporting a mobile session of a user equipment (UE) having an specific identifier, such as an IP address or terminal identification number.

Method and apparatus for tracing mobile sessions

A system and method for substantially preventing firewall generated communication losses in regard to communications by authorized users in a managed computer network system is provided. The method comprises transmitting one or more status inquiry commands to at least one node in the managed computer network system, wherein the status inquiry command requests a first quantity of objects from the at least one node; receiving a non-zero quantity of objects response from the at least one node; and limiting communications through the firewall in the managed computer network system with the at least one node to a message size substantially equivalent to the received non-zero quantity of objects response from the at least one node, thereby substantially preventing firewall generated communication losses in the managed computer network system.

System and method for determining a maximum packet data unit (PDU) payload transmission size for communicating in a managed computer network system

The invention includes a method and apparatus for configuring logical connectivity for a network comprising a plurality of nodes. A method includes determining a physical topology of the network, determining a set of LSP paths based on the physical topology of the network, and determining a set of LSPs using the set of LSP paths, where the set of LSPs includes a plurality of LSPs adapted for providing full logical connectivity between the nodes of the network. The physical topology is determined using information indicative of physical connectivity between nodes of the network. The set of LSP paths includes, for each pair of nodes in the network, at least two logical paths between the nodes of the node pair. The set of LSPs includes a plurality of LSPs adapted for providing full logical connectivity between the nodes of the network. The full logical connectivity between the nodes of the network may be maintained in response to physical topology change events, such as addition of nodes to the network removal of nodes from the network, and the like.

Method and apparatus for providing full logical connectivity in MPLS networks

Various exemplary embodiments relate to a network management system (NMS) and a method performed on the NMS including one or more of the following: receiving a notification of a new endpoint discovered in the network, the new endpoint representing an endpoint in a multi-chassis pair; determining that an address of the new endpoint conflicts with an address of a first existing endpoint of an existing multi-chassis pair, wherein the first existing endpoint is currently paired with a second existing endpoint; determining whether the new endpoint or the first existing endpoint is a proper endpoint of the existing multi-chassis pair; and when the new endpoint is the proper endpoint of the existing multi-chassis pair, updating the data representing the topology in the storage module to replace the first existing endpoint with the new endpoint as paired with the second existing endpoint.
