Abstract

Abstract:

With the explosive growth of the mobile internet applications，coordination between mobile networks and WLAN is playing an important role in telecom operators’ smart pipe development. The feasibility of 3GPP-WLAN interworking structures with consideration of the capability of existing networks and UE，were studied. A feasible structure based on the 3GPP SaMOG standard was also proposed，with corresponding solutions to the key issues in its implementation.

Key words: mobile internet, mobile network, WLAN, nterworking, SaMOG

场景	耦合度	需求
客户关系和账单统一	松耦合	移动网络接入和WLAN接入、计费点是分离的，但在IT系统出账单上实现了统一账单，移动用户和 WLAN用户客户关系上实现了关联；无需网络支持
基于移动网络的统一认证	松耦合	WLAN接入通过移动网络HSS实现统一的认证、计费，基于3GPP的SIM/USIM卡的认证方式，但WLAN只提供与Internet的IP连接；需要网络支持
统一接入移动分组域网络	紧耦合	在接入认证基于移动网络的基础上， WLAN 业务流也接入3GPP 分组域，向WLAN用户提供了3GPP业务，进一步可以为WLAN 业务流提供移动网络的QoS机制保障服务；需要网络支持
接入移动分组域网络，提供（无缝的）业务连续性	紧耦合	移动网络与WLAN实现有机协同，在移动网络、WLAN间支持业务的连续性，提供移动网络、WLAN间的无缝切换机制；需要网络支持

方案	网络改造要求	终端要求	方案分析
S2a	固网 BRAS 支持移动网的 EAPSIM/AKA 认证、GTP/PMIP 隧道协议及 WLAN 接入的业务分流控制	无特殊要求	对固网改造较大，由于BRAS按区域部署，因此涉及设备、厂商众多，推动难度大
S2b	固网无特殊要求，移动网络需引入ePDG网元	终端需支持IPSec协议	终端支持成为方案的瓶颈，目前主流终端都还不支持 IPSec 协议，且IPSec协议额外开销比较大，对终端待机时间提出巨大挑战
S2c	对固网无特殊要求，移动核心网元PDN GW 需支持DSMIPv6	终端需支持DSMIPv6	终端支持成为方案瓶颈，目前还没有支持DSMIPv6 的手机芯片，网络也未支持DSMIPv6
