Description

一种跨系统网络信息交互的方法、 终端系统网络网元
技术领域
本发明涉及通信领域,无线局域网( WLAN )及其后续演进系统如( High Efficient WLAN (高效 WLAN ) , 简称 HEW )和 3 GPP 互联系统架构下的 一种跨系统网络信息交互的方法、 终端系统网络网元。
背景技术
移动互联网是当今世界发展最快、 市场潜力最大、 前景最诱人的产业, 而无线接入是移动互联网行业的核心技术。 目前, 多种先进的无线接入技术 ( Multiple Radio Access Technology, 简称 Multi-RAT )并存, 使得用户终端 高速接入无线网络, 并享受高质量的服务。 其中, 典型的技术包括以 LTE为 代表的无线广域网接入技术, 和以 IEEE 802.11为代表的无线局域网技术。 WLAN是利用无线通信技术在一定局部范围内建立的网络,架构示意图见图 1 , 与 LTE ( Long Term Evolution , 长期演进)相比 WLAN 的覆盖范围小, 接入速率高, 使用成本低。
LTE网络作为 3GPP ( 3rd Generation Partnership Project, 第三代合作伙 伴计划)无线通信家族网络下的典型代表, 由 E-UTRAN ( Evolved UTRAN ( UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) Terrestrial Radio Access Network陆地无线接入网)基站 eNB( Evolved NodeB ) 和演进分组交换中心 ( Evolved Packet Core, 简称 EPC )组成, 网络扁平化。 其中, EUTRAN包含和 EPC通过 S1接口连接的 eNB的集合, eNB之间能 通过 X2连接。 Sl、 X2是逻辑接口。 一个 EPC可以管理一个或多个 eNB, 一个 NodeB也可以受控于多个 EPC, —个 eNB可以管理一个或多个小区。 LTE-A系统由 LTE系统演进而来 , 网络架构与 LTE—致。 LTE是 4G技术 , 与 3G相比, LTE具有各方面的技术优势: 更高的数据率、 低延时的传输、 业务服务质量(QoS )保障。 与 WLAN相比, LTE具有更广的覆盖, 支持 用户终端高速移动和漫游。
随着未来通信网络的不断演进, 各种制式的网络模式共存是不可避免的 趋势, 包括 2G、 3G、 LTE融合组网, 3GPP-WLAN融合组网等, 3GPP-WLAN 融合组网示意图见图 2。由于 WLAN和 3GPP无线通信家族网络的互补特性, 3GPP-WLAN的互联互通成为设备制造商、 系统集成商、 运营商以及科研机 构的热点问题之一。
在多种接入技术并存的条件下, 如何选择合适的接入网络, 保障用户终 端的 QoS需求, 以及避免不必要的乒乓切换是一个至关重要的问题。 目前历 史信息中历史小区只包含 UTRAN\LTE\GERAN ( GSM ( Global System for Mobile Communications,全球移动通讯系统 ) EDGE ( Enhanced Data Rate for GSM Evolution , 增强型数据速率 GSM演进技术) Radio Access Network ) 小区信息, 且只在切换流程中携带, 作用是用于 RRM ( Radio Resource Management, 无线资源管理)决策, 主要是解决乒乓切换。 LTE历史小区信 息包括 Global Cell ID(小区全局标识)、 Cell Type(小区类型 X ENUMERATED (枚举型态 ) (verysmall, small, medium, large, ... ) ) 、 Time UE stayed in Cell (终端驻留小区的时间) 、 HO Cause Value (切换原因值) (UE切换 from E-UTRAN to UTRAN 的原因 ) 。 UTRAN 历史小区信息包括小区 ID ( PLMN+CID )、 Cell Type ( ENUMERATED(macro, micro, pico, femto, ...) )、 Time UE stayed in Cell。而对终端在 WLAN系统下的历史记录目前并无定义, 并且由于目前 LTE和 WIFI之间没有直接的跨系统切换流程,也就意味着 UE 从 LTE切换到 WIFI或者从 WIFI切换到 LTE系统, 之前的 UE驻留系统历 史信息将无法通过相关切换流程方式传递到目标系统。 网络侧如果知道 UE 在 WLAN系统下的业务类型、驻留时间、 流量等相关信息, 那么网络侧可以 才艮据该信息优化 ANDSF ( Access Network Discovery and Selection Function, 接入网发现和选择功能)策略或者 RAN ( Residential Access Network, 居民 接入网) 策略, 实现空口配置参数的优化和测量事件参数优化以及避免 3GPP-WLAN系统间乒乓切换。
因此, 在多种接入技术并存的时候, 跨系统场景下如何将终端在 WLAN 系统下的历史记录信息进行有效传递和利用的问题需要得到解决, 怎样才能 更好实现资源管理和跨系统切换策略优化, 同时提升用户满意度。 发明内容
本发明要解决的技术问题是提供一种跨系统网络信息交互的方法、 终端 系统网络网元, 以实现终端历史信息跨系统交互。
