Outline

Reconfigurable core network A “Reconfigurable mobility management platfor

m” is proposed Expected to provide a new direction for the heter

ogeneous networks integration Two extensions Security extension: Authentication, Authorization

… SIP extension: Reconfigurability between SIP and

MIP

SIP extension

Currently, only MIP is used as macro-mobility protocol in RAMP. MN could choose SIP or MIP as the

mobility management protocol while roaming across macro domain.

Integrate SIP in the RAMP architecture In SIP, MN needs to established a SIP

session with a CN while MIP needs not.

Switch form MIP to SIP while roaming

1. Roaming

0. Data path using MIP

2.1 Location update

2.2 Re-invite CN. And new data path.

Security Issues

Architecture security issue: Handle issues such as authentication and

authorization in the core network. Prevent potential security holes in the

core network.

Reconfigurable authentication protocol: MN could select protocol to authenticate

itself to the core network
