Systems and methods for placing virtual serving gateways for mobility management

Abstract

Methods and systems for determining placement of a virtual serving gateway. The method includes obtaining a set of input information. The input information includes network information and configuration information providing one or more parameters for placing the virtual serving gateway, and includes at least one mobility insensitivity criterion. Placement of the virtual serving gateway at one or more physical hosts is determined in accordance with the network information and the configuration information. The virtual serving gateway is distributively placeable across physical hosts. A set of output information is generated. The output information includes information identifying placement of the virtual serving gateway at the physical hosts, and a hosting percentage for each physical host.

1 . A logical virtual gateway comprising:
 a first host comprising a processor and a computer readable storage medium for storing instructions that when executed by the processor cause the first host to:
 instantiate a first virtual gateway fractional component; and 
   a second host comprising a processor and a computer readable storage medium for storing instructions that when executed by the processor cause the second host to:
 instantiate a second virtual gateway fractional component that in conjunction with the first virtual gateway fractional component provides a logical virtual gateway for association with a user equipment, wherein each of the first and second virtual gateway fractional components treats a fraction of traffic associated with a user equipment associated with the logical virtual gateway. 
   
     
     
         2 . The logical virtual gateway of  claim 1 , wherein the logical virtual gateway is a virtual serving gateway. 
     
     
         3 . The logical virtual gateway of  claim 1 , wherein the logical virtual gateways is a virtual user-specific gateway. 
     
     
         4 . The logical virtual gateway of  claim 1 , wherein the first and second virtual gateway fractional components serve as anchor points for the user equipment associated with the logical virtual gateway. 
     
     
         5 . The logical virtual gateway of  claim 1 , wherein the traffic associated with the user equipment is at least one of uplink and downlink traffic. 
     
     
         6 . The logical virtual gateway of  claim 1 , wherein the first host are distinct physical hosts. 
     
     
         7 . The logical virtual gateway of  claim 1 , wherein the first host and the second host are virtual entities instantiated upon a common resource pool. 
     
     
         8 . The logical virtual gateway of  claim 1 , wherein the first host has access to a first content cache and the second host has access to a second content cache. 
     
     
         9 . The logical virtual gateway of  claim 8 , wherein the first content cache and second content cache are the same content cache. 
     
     
         10 . The logical virtual gateway of  claim 8 , wherein content stored by the first content cache is one of the same as, different than and overlapping with, content stored by the second content cache.
