Description

公用数据网的建立方法、 装置及系统 技术领域  Method, device and system for establishing public data network
本发明涉及网络通信技术领域, 尤其涉及一种公用数据网的建立方 法、 装置及系统。  The present invention relates to the field of network communication technologies, and in particular, to a method, device and system for establishing a public data network.
背景技术 Background technique
随着通信技术的发展, 公用数据网 ( Public Data Network, 简称 PDN) 得到了广泛的应用。 当前的 PDN网络有 艮多类型的架构, 例如演进的分组 系统 ( Evolved Packet System, 简称 EPS ) 架构、 分布式移动性管理 With the development of communication technologies, the Public Data Network (PDN) has been widely used. The current PDN network has many types of architectures, such as Evolved Packet System (EPS) architecture, distributed mobility management.
( Distributed Mobility Management, 简称 醒) 架构等。 在 EPS 架构 中, 包括分组数据网网关 ( Packet Data Network Gateway, 简称 P_GW)、 服务网关 (Serving Gateway, 简称 S_GW)、 移动性管理实体 ( Mobility Management Ent i ty , 简称 MME)、 演进基站 ( evolved Node Base s tat ion, 简称 eNB) 以及用户设备 ( User Equipment, 简称 UE)。 (Downware Mobility Management, abbreviated wake up) architecture. In the EPS architecture, including a Packet Data Network Gateway (P_GW), a Serving Gateway (S_GW), a Mobility Management Entity (MME), and an evolved Node (evolved Node) Base s tat, eNB for short, and User Equipment (UE).
具体的 EPS架构如图 1所示, 在 UE开机时, UE所在的 eNB会选择 UE 需要附着的 MME, 并由 MME选择 UE要附着的 S-GW和 P-GW。 之后需要建立 EPS ,默认 载, 即从 UE到 eNB, 再到 S-GW, 再到 P_GW。 在为 UE月良务的过 程中, P-GW作为移动性管理的锚点, 一般会保持不变。 当 UE没有业务进 行, 即处于 IDLE态, 发生移动时, 如果 UE检测到当前的 eNB不在跟踪区 The specific EPS architecture is as shown in FIG. 1. When the UE is powered on, the eNB where the UE is located selects the MME to which the UE needs to be attached, and the MME selects the S-GW and the P-GW to which the UE is to attach. After that, the EPS needs to be established, and the default load is from the UE to the eNB, then to the S-GW, and then to the P_GW. In the process of UE UE service, P-GW as the anchor of mobility management will generally remain unchanged. When the UE does not have a service, that is, in the IDLE state, when the mobile occurs, if the UE detects that the current eNB is not in the tracking area.
( Tracking Area, 简称 TA)歹 'J表中,贝' J会发起 3艮踪区更新( Tracking Area Update, 简称 TAU ) 流程。 如果在 TAU流程中, UE所附着的 S-GW发生改 变, 则会在新的 S-GW建立承载资源, 由于 P-GW—般保持不变, S-GW到 P-GW之间的核心网的承载一般已经预先建立好,因此只需要建立 UE到 eNB 再到 S-GW之间的承载连接即可。 (Tracking Area, referred to as TA) 歹 'J table, Bay' J will initiate a Tracking Area Update (TAU) process. If the S-GW attached to the UE changes in the TAU process, the bearer resource is established in the new S-GW, and the core network between the S-GW and the P-GW remains unchanged due to the P-GW. The bearer is generally pre-established, so only the bearer connection between the UE and the eNB and then to the S-GW needs to be established.
在 DMM架构中, 包括本地网关 (Local Gateway, 简称 L-GW)、 移动 性管理 MME、 演进基站 eNB以及用户设备 UE等。 具体的 DMM架构一般如 图 1 所示, 在控制面存在 MME、 策略与计费规则功能单元 (Po l i cy and Char g i ng Con t ro l , 简称 PCRF ) 等实体的集中控制功能, 在接入网部署 L-GW来作为移动性管理的锚点, 为 UE分配 I P地址, 创建 EPS承载。 在 图 2中, 每个 eNB都有一个 L-GW与之对应。 当 UE发生移动时, 其所附着 的 eNB和 eNB对应的 L-GW均会改变, 为了保证业务的连续性, 需要建立 当前的网关与之前为 UE分配 IP地址的网关之间的隧道, 在 UE移动速度 较快时, 所附着的 eNB和 eNB对应的 L-GW改变较快, 从而需要建立当前 的网关与之前为 UE分配 I P地址的多个网关之间的多条隧道,浪费了系统 资源。 In the DMM architecture, a Local Gateway (L-GW), a mobility management MME, an evolved base station eNB, and a user equipment UE are included. The specific DMM architecture is generally like As shown in Figure 1, there is a centralized control function of entities such as MME, Policy and Charging Rules Function Unit (PCRF) on the control plane, and L-GW is deployed on the access network. As an anchor of mobility management, an IP address is assigned to the UE, and an EPS bearer is created. In Figure 2, each eNB has an L-GW corresponding to it. When the UE moves, the L-GW corresponding to the eNB and the eNB to which the UE is attached changes. To ensure the continuity of the service, a tunnel between the current gateway and the gateway that previously assigned the IP address to the UE needs to be established. When the moving speed is fast, the L-GW corresponding to the attached eNB and the eNB changes rapidly, so that multiple tunnels between the current gateway and multiple gateways that previously allocated IP addresses to the UE need to be established, which wastes system resources.
发明内容 Summary of the invention
