信息处理方法及装置、 无线接入网系统
技术领域 本发明涉及通信领域， 具体而言， 涉及一种信息处理方法及装置、 无线接入网系 统。 背景技术 从 20世纪 80年代第一代移动通信系统发展至今， 移动通信技术已经步入 4G时 代， 用户的移动通信需求也经历了从单一的语音业务， 到语音和基础数据业务， 到数 据业务爆发增长的过程， 移动通信已经逐渐上升到目前的移动互联网时代。 移动互联 网时代， 新的移动应用需求， 那些高质量、 高速率、 低延时的移动应用需求出现了爆 发式的增长，根据国际电信同盟（International Telecommunications Union,简称为 ITU) 的预测， 2010年到 2015年间， 移动通信业务相对于此前将出现 15~30倍的增长， 到 2020年， 移动通信业务更是有可能出现超过 500倍的增长。 移动通信业务的爆发式增长和用户对移动通信体验的更高期望， 比如更高的吞吐 量， 更低的延迟， 更快的速率， 更廉价的费用， 都驱使现有移动通信技术和移动通信 网络进一步向前发展升级， 包括扩容网络能力， 增强网络覆盖， 增强不同网络不同小 区之间的协作， 提高网络部署的灵活性， 降低网络部署的费用等。 对用户通信行为和习惯的统计可以发现， 大部分高数据流量的通信集中出现在室 内环境和热点地区， 比如商场， 学校， 用户家里， 大型演出、 集会场所等， 考虑室内 环境和热点地区区域分布广而散、 单区域范围小、 用户集中等特点， 一种低功率节点 (Lower Power Node, 简称为 LPN) 应运而生。 从概念上讲， LPN是指发射功率比传 统宏网络中的宏节点 （Macro Node)或基站（Base Station, 简称为 BS) 的发射功率低 的无线接入网节点， LPN可以是微基站（Pico Node), 家庭基站（ Femto/Home (e)NB ) 以及其他可能出现的任何发射功率低于传统 Macro Node或 BS的蜂窝节点。 LPN的部 署， 可以有效扩容网络能力， 增强网络覆盖， 最终提高终端用户的吞吐量， 提高终端 用户的通信体验。此外由于 LPN发射功率低， LPN可以做到即插即用， 因此网络运营 商可以灵活方便的根据需要部署 LPN，网络运营商甚至可以把部署 LPN的权限开放给 企业、 学校等用户甚至个人用户， 从而提高网络部署的灵活性， 与此同时降低网络部 署和运维费用。 为实现对网络而言扩容网络能力， 增强网络覆盖， 提高网络部署的灵活性， 降低 网络部署的费用， 对用户而言提高用户的通信体验的目标， LPN有望被大量部署， 比 如对于 4G长期演进（Long Term Evolution, 简称为 LTE)系统而言， 在第三代合作伙 伴计划（the 3rd Generation Partner Project, 简称为 3GPP)版本 12 (Released)及 R12+ 之后， 在传统宏网络基础上有望部署大量 LPN， 即包括室内环境也包括室外环境。 部 署大量 LPN提高用户的通信体验， 包括提高用户设备 （User Equipment, 简称为 UE) 的吞吐量， 提高用户设备的移动性能等。 针对相关技术中大量信令冲击， 导致无线接入网和核心网负荷比较大的问题， 目 前尚未提出有效的解决方案。 发明内容 针对大量信令冲击， 导致无线接入网和核心网负荷比较大的问题， 本发明实施例 提供了一种信息处理方法及装置、 无线接入网系统， 以至少解决该问题。 根据本发明实施例的一个方面， 提供了一种信息处理方法， 包括： 通过接口代理 功能网元为核心网网元和无线接入网网元之间提供第一接口代理； 或通过所述接口代 理功能网元提供所述第一接口代理和为所述无线接入网网元之间提供第二接口代理； 通过所述第一接口代理或所述第二接口代理进行信息处理。 优选地， 通过所述第一接口代理进行信息处理包括： 通过所述第一接口代理进行 信息处理包括： 通过所述第一接口代理进行所述核心网网元和所述无线接入网网元之 间的 S1接口代理；通过所述第二接口代理进行信息处理包括：通过所述第二接口代理 中继所述无线接入网网元之间的 X2接口信令。 优选地， 通过所述第一接口代理进行所述核心网网元和所述无线接入网网元之间 的 S1接口代理包括以下之一： 通过所述接口代理功能网元进行所述核心网网元和所述无线接入网网元之间的
