In the existing PMIP scheme for SAE-based mobile networks such as LTE, data delivery is performed by GTP between eNB and S-GW, and also between eNBs in X2-based handover, while GRE protocol is used between S-GW and P-GW. However, the use of GTP tunnels between eNB and S-GW and between eNBs tends to induce large tunneling overhead for packets. Existing scheme also tends to incur large registration...
The newly emerging 5G mobile communication system requires an effective design of core network to cope with the mobile data traffic explosions. In this paper, we propose a new architecture for 5G mobile core network, RB-Core, to efficiently deal with such the data traffic explosion problem. The proposed RB-Core network is designed by adopting a distributed architecture and by using the Routing Bridge...
The locator identifier separation protocol (LISP) has been made as an identifier-locator separation scheme for scalable Internet routing. However, the LISP was originally designed for fixed network environment, rather than for mobile network environment. In particular, the existing LISP mobility control schemes use a centralized map server to process all the control traffics, and thus they are intrinsically...
The Locator Identifier Separation Protocol (LISP) has been made as an identifier-locator separation scheme. However, the issue of handover for mobile host is still a serious challenge in LISP. The existing LISP-based handover schemes tend to induce large handover delay and packet loss. To overcome such problems, we propose a new handover control scheme, in which the Map Request and Reply messages...
