US Patent:

7107061, Sep 12, 2006

Filed:

Jun 28, 2002

Appl. No.:

10/184424

Inventors:

Carlos Molina - Plano TX, US
Carlos Motta - Richardson TX, US
Anabella Arosemena - Dallas TX, US

Assignee:

Nortel Networks Limited - St. Laurent

International Classification:

H04Q 7/20

US Classification:

455453, 455450

Abstract:

Provided is a system and method for controlling overload in a telecommunications network. The network carries a traffic load that may exceed a maximum resource capacity and drive the network into an overload state. The method determines whether an overload state has occurred by comparing a current resource capacity to an overload onset threshold. If the threshold has been exceeded, the method blocks a certain percentage of traffic. An incrementally increasing percentage of traffic is blocked until the resource capacity crosses an overload abatement level. The method then incrementally decreases the percentage of blocked traffic until no traffic is blocked.

International Classification:

H04L 12/26

US Classification:

370232

Abstract:

Provided is a system and method for controlling overload in a telecommunications network. The network carries a traffic load that may include traffic of multiple classes and mixed types. The method determines whether the traffic load has exceeded one or more overload thresholds. Each threshold is associated with a class or type of traffic. If one or more of the thresholds have been exceeded, the method sets a timer associated with the exceeded threshold. Each timer has a state (e. g. , expired or not expired) and the states of the timers are used to look up a function for controlling the overload. The function is used to alter the traffic flow of one or more of the traffic classes.

International Classification:

H04W 68/00

US Classification:

455458, 4554561, 455453, 455445, 455440, 455434

Abstract:

An MME keeps track of network tracking mobility characteristics by periodically updating a TA transition probability matrix derived from a global table that maintains UE movement data in the network by noting current TA and most recently known previous TA of each EU for every TAU event and paging event. The MME also maintains data of the number of paging events and TAUs performed by each UE and stores a paging ratio versus TAU for each UE. The UE characteristics, UE paging ratio, and network mobility characteristic are utilized in an algorithm that constructs a TA list for each UE designed to minimize the overall traffic cost function for paging events and TAU events for that UE and the overall network. Optionally, the TA list for each EU is constrained to meet certain minimum performance characteristics such as a predetermined paging success rate target and/or a predetermined delay bound target.

International Classification:

H04L 12/26

US Classification:

370221

Abstract:

This disclosure describes a method to provide stateful geographic redundancy for the LTE MME (Mobility Management Entity) function of the 3GPP E-UTRAN Evolved Packet core (EPC). The method provides MME many-to-one (“n:1”) stateful redundancy by building upon the S1-Flex architecture, which enables a MME Pool Area to be defined as an area within which a UE (User Equipment) may be served without need to change the serving MME. Geographic redundancy is achieved by utilizing a standby MME node deployed to backup a pool of MME nodes, with the standby MME node designed to handle the large volume of journaling or synchronization messages from all the MME nodes in the pool. The standby MME node takes over the personality and responsibility of any MME node in the pool that has failed, with minimal impact to subscribers that were being served by that failed MME node.

International Classification:

H04Q 734

US Classification:

370468

Abstract:

A communication system provides wireless voice and multimedia communications and includes a base station, a plurality of wireless mobile units and a bandwidth allocator. The base station provides wireless coverage throughout a service area and has a bandwidth for providing the wireless coverage. The plurality of wireless mobile units operate within the service area and communicate with the base station to transmit and receive both voice communications and multimedia communications. The bandwidth allocator selectively allocates the bandwidth in response to wireless multimedia communication requirements to achieve a minimum transmission rate for multimedia communications. The communication system may include a plurality of channels, each having a channel bandwidth with the bandwidth allocator selectively allocating the channels in response to the multimedia communication requirements to achieve the minimum transmission rate. The base station may also include a plurality of data modems, each of the data modems providing a respective portion of the bandwidth, the bandwidth allocator selectively allocating the plurality of data modems of the base station to achieve the minimum transmission rate. Further, at least one of the wireless mobile units may include a plurality of data modems with the bandwidth allocator selectively allocating the data modems of the wireless mobile unit to achieve the minimum transmission rate.
