移动虚拟网络运营技术研究

[摘要] 探讨了为实现移动虚拟网络运营（MVNO）核心网网元需要解决的关键技术问题，包括：归属位置寄存器（HLR）需要提供“虚拟”HLR功能；电路交换（CS）网元的移动交换中心服务器（MSC Server）/拜访位置寄存器（VLR）需要提供等效公众陆地移动网（EPLMN）功能、网络标识和时区（NITZ）功能，MSC Server/VLR还需要解决路由选择的问题；分组交换/演进分组核心网（PS/EPC）网元服务通用分组无线业务支持节点/网关通用分组无线业务支持节点/移动性管理实体/分组数据网网关（SGSN/GGSN/MME/PGW）需要支持多公众陆地移动网（PLMN）功能以及虚拟路由转发表（VRF）等。

[Abstract] Core network elements require solutions in order to realize mobile virtual network operator (MVNO). The home location register (HLR) needs to support virtual HLR function; the mobile switching center (MSC) server and visitor location register (VLR) of circuit switching needs to support equivalent public land mobile network (EPLMN), network identity and time zone (NITZ), and the routing-selection strategy; and serving GPRS support node (SGSN), gateway GPRS support node (GGSN), mobility management entity (MME) and PDN Gateway (PGW) all need to support multiple PLMN functions and virtual routing forwarding (VRF).
