Main Consideration for Evolution

1

Migration directly from legacy PS

 _{Legacy GSN should support LTE access}

 _{Legacy GSN should provide huge capacity for} LTE

 _{Legacy GSN should support the all IP} networking

 Lower CAPEX at initial stage

 _{Higher OPEX, because of GSN ‘s lower capacity} and integration

 _{Upgrading from GSN may impact the legacy} network

2

Build new EPC and integrate 2/3G

 _{EPC has the Huge capacity for LTE access}  _{EPC should support All IP networking}  _{EPC should support 2/3G access}  _{Higher CAPEX at initial stage}
