20110235505 | Efficient deployment of mobility management entity (MME) with stateful geo-redundancy - 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. | 09-29-2011 |
20110294524 | TRACKING AREA MANAGEMENT METHOD AND APPARATUS FOR LONG TERM EVOLUTION TELECOMMUNICATION SYSTEMS - 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. | 12-01-2011 |
20130044730 | Optimized Home Evolved NodeB (eNB) Handover in an LTE Network - A method to provide an optimized intra-HeNB GW handover operation that reduces signaling to and from an LTE MME (Mobility Management Entity) function of the 3GPP E-UTRAN Evolved Packet core (EPC). In operation, an HeNB Gateway (GW) intercepts handover requests from a source HeNB to a target HeNB and processes these requests locally, with minimal interaction from the MME. Where possible, messaging to and from the MME is minimized and/or reduced, irrespective of the 3GPP requirement that the GW relay all handover-related messages to the MME. | 02-21-2013 |
20160088518 | METHOD OF DIRECTED UE RELOCATION WITHIN AN MME/SGSN FLEX POOL - Example implementations described herein are directed to a support node apparatus configured to support a wireless network system. The support node apparatus can be in the form of a mobility management entity and/or a serving general packet radio service. The example implementations directed herein can provide a network resource identifier and/or a globally unique temporary identifier to an associated user equipment to facilitate the transfer of the user equipment from a source support node apparatus to a target support node apparatus. In example implementations, the target support node apparatus can thereby be directly specified by use of the identifier. | 03-24-2016 |
