下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互组合。
本文中的终端是一种固定移动融合 ( Fix-Mobile Convergence , FMC )终 端, 此类终端既可接入无线局域网, 也可以接入 CDMA lx、 CDMA evdo、 GSM/GPRS、 WCDMA和 TD-SCDMA等移动网络中, 本文中将此类终端简 称为终端。
本实施方式中, 当终端建立多个网络接入后, 会根据网络接入优先级选 择一个网络接入作为当前可用网络接入, 比如无线局域网链路, 并通过 SIP 信令发布给策略服务器, 以便在其他终端发起对本端的业务交互时, 可以查 询到当前选择的可用网络接入以及相应的 IP地址。相当于在开机或者未启动 任何应用的情况下配置一个缺省的网络接入。
终端通过对不同网络接入数据流量和业务运行状态的监测, 在业务启动 时, 根据终端上预置策略中业务的网络接入优先级, 为业务动态选择网络接 入, 并通过与策略服务器的交互, 发布当前选择的网络接入, 同时可以从策 略服务器获知业务对端的当前可用网络接入的选择情况。 当终端某个网络接 入出现拥塞时, 终端可以选择一个相对空闲的网络接入, 当本端发起一个新 的业务或接收到一个新的来自对端的业务请求时, 由当前选择的网络接入进 行承载, 避免了终端上多路网络接入的数据负载不均衡的问题。
实现本实施方式的方法的前提条件是具备至少两个网络接入能力的终 端, 并获取到各网络分配的 IP地址。 终端通过一个五元组来分流各项业务的 数据, 五元组内容包含: 源 IP地址、 源端口、 目的 IP地址、 目的端口和传 输层协议, 分别对应发起业务的终端的 IP地址和端口、 业务对端的 IP地址 和端口以及传输层协议名称。 源 IP地址为发起业务的终端在网络接入上获取 的 IP地址。
本实施方式在终端中增加接口选择模块, 用以进行网络接入选择, 网络 接入选择的判定条件为各网络接入上的负载情况和终端上配置的策略。 当终 端启动某个业务并发起网络数据传输时, 接口选择模块根据策略中业务对应 的网络接入优先级, 先考察无线局域网链路, 在无线局域网链路上数据流量 已经达到或超过阔值, 而蜂窝网络分组域链路上数据流量没有达到阔值, 且 满足业务对接入网络的要求时, 终端选择蜂窝网络分组域链路作为当前业务 的网络接入。 终端在为业务分配五元组时, 将五元组中源 IP地址设置为蜂窝 网络中分组链路上获取的 IP地址, 源端口和目的端口的选择取决于业务本身 的要求, 比如浏览器应用通常只在 80端口上收发数据。 通过上述过程, 作为 发送方的终端完成对网络接入的选择。
终端与策略服务器间信令釆用 SIP协议, SIP信令各个头域字段釆用标准 定义, SIP信令中的用户身份标识, 釆用 SIP URI格式, 基于用户 MSISDN 号和配置的域名扩展, 例如用户 MSISDN号为 13313333133 , 域名扩展为 cmobile . com , 则用户 SIP身份标识为 sip :13313333133 @cmobile . com。 SIP信 令的收发与解析由终端上的接口选择模块完成。
策略服务器设置为接收和下发终端发布的当前可用网络接入的信息。 为 完成终端与策略服务器之间信令交互, 终端在满足策略服务器的可访问条件 时, 即当终端的接口选择模块与服务器之间的消息路由畅通时, 接口选择模 块发起注册过程。 判断服务器路由是否畅通可以通过服务器域名解析的方式 进行,或者确定某一类网络接入可以保证服务器路由畅通,例如通过 WCDMA 分组链路才能访问策略服务器。 当终端发起注册时, 釆用 SIP信令中 Register 消息, 身份标识釆用上文描述的基于 MSISDN号扩展的 SIP URI。 信令中各 个头域字段中涉及的终端 IP地址均设置为满足策略服务器路由畅通的网络接 入上获取的 IP地址。 Register釆用 RFC3261规范定义的标准格式。
终端在选择了当前可用网络接入后, 通过 SIP Publish消息向策略服务器 通知选择结果, 消息体釆用自定义 XML编码格式, 格式如下: <access_preference>
<id>sip :13313333133 @cmobile . com</ id>
<name>WLAN</name>
<address> 10.11.12.13</address>
</access_preference>
以上消息体中 , <access_preference>^。</access_preference>分另 ll为接入参 数的起始和结束标识; <id>sip :13313333133 @cmobile .。0111</ (1>表示终端标识; <name>WLAN</name>表示网络接入的名称; <address>10.11.12.13</address> 表示 IP地址。
终端在发起业务之前, 还需了解业务对端对网络接入的选择。 终端向策 略服务器发起针对业务对端的订阅请求, 订阅请求为 SIP信令的 Subscribe消 息。 终端向策略服务器发出对业务对端的网络接入选择的订阅请求, 即 SIP 的 Subscribe信令,终端在收到策略服务器返回的通知消息后,即 SIP的 Notify 信令, 得到业务对端的当前可用网络接入。 Notify釆用 RFC3261定义的标准 格式, 消息体釆用自定义 XML编码格式, 格式釆用上文描述的 Publish消息 体格式。
下面结合附图对本发明的实施方式进行更详细的说明。
结合图 1说明实现本实施方式的终端的各个模块和接口。 终端新增接口 选择模块和接口监测模块, 接口选择模块设置为管理业务配置信息, 每条配 置信息对应于业务中的每个媒体流(包括视频、 音频、 图像和字符文本等), 业务配置信息包括: 占用的端口、 缺省流量、 协议名称和预留扩展项。 配置 信息由业务通过图 1中接口 2向接口选择模块注册, 也可通过独立的设置界 面完成各个业务配置信息的注册。
业务使用标准的 TCP/IP协议提供的 Socket接口,完成应用数据收发,参 见图 1接口 1。 接口选择模块在确定了网络接入后, 通过接口 4 , 设置 TCP/UDP协议模 块中的路由选项, 指定当前网络接入对应的设备接口为缺省路由中的本地设 备接口, 部分终端操作系统支持路由表设置, 接口 4可以通过操作系统提供 的路由表控制接口完成路由设置。
接口选择模块在为终端发起的业务选择本地的网络接入时, 根据业务的 网络接入优先级和从接口监测模块查询的网络接入的数据流量进行选择, 首 先从根据业务的网络接入优先级挑选出一个网络接入, 判断该网络接入的数 据流量与业务配置信息中的缺省流量之和是否大于该网络接入的负荷上限, 如果大于, 则从网络接入优先级中挑选下一级的网络接入, 再判断否则判断 该网络接入的数据流量与业务配置信息中的缺省流量之和是否大于该网络接 入的负荷上限; 如果不大于, 选择该网络接入作为本地的网络接入。
接口选择模块从策略服务器订阅业务对端的当前可用网络接入的信息 后, 按照本地的网络接入的信息和业务对端的当前可用网络接入的信息配置 业务连接, 包括: 为该业务连接配置源 IP地址、 源端口、 目的 IP地址、 目 的端口以和传输层协议, 其中, 源 IP地址为本地的网络接入的 IP地址, 目 的 IP地址为所述业务对端的可用网络接入的 IP地址, 源端口和目的端口均 为业务对应的业务配置信息中业务占用的端口, 传输层协议为所述业务配置 信息中的协议名称。
TCP/UDP协议模块在发送数据时通过接口 3得到发送数据所需设备接口 和源 IP地址, 设备接口和源 IP均通过路由选项得到。
接口选择模块通过接口 7向接口监测模块查询各个网络接入上的实时流 量统计。
TCP/UDP协议模块通过接口 5和接口 6收发 IP数据报文,接口 6为数据 链路层与 IP层之间的开放接口, 与接口 1一样, 为通用实现。 接口 5与接口 6的区别在于所连接设备的不同, 图 1 中所示 "设备" 为一概念模块, 实际 指代了包含射频、 无线协议栈、 相关设备驱动在内的无线设备模块。 "设备 一"指代了在无线分组域链路提供 IP链路的设备,如 WCDMA或 TD-SCDMA 或 LTE终端等, 而 "设备二" 指代了如无线局域网 802.11a/g等类的无线设 备, 两者的区别在于提供给上层协议的层次不同, "设备一" 直接提供 IP功 能接口, 而 "设备二" 提供数据链路层的功能接口。 接口 5与接口 6的实际 功能相同, 均为 IP报文收发接口。
接口监测模块通过接口 8完成各个接口上数据流量监测, 可以釆用在 IP 协议中收发接口中注册回调函数来实现。
IP获取模块只用于 "设备二" 所在链路上。 "设备一" 在分组域链路建 立过程中, 由网络侧完成 IP申请和分配过程。 当无线局域网链路建立成功之 后, 通常终端釆用动态主机设置协议( Dynamic Host Configuration Protocol, DHCP )获取合法 IP地址, IP协议模块通过接口 9获知 IP地址。 设备一所获 IP地址可由 TCP/UDP协议模块通过接口 5获取。
IP协议模块调用数据链路层的接口 10完成数据收发。 接口 11为设备提 供的驱动接口。 两部分均为开放接口, 具体实现根据硬件厂家定义或数据链 路层协议而定。
图 3为网络结构示意图, 图中策略服务器连接移动网络分组域网关, 此 处默认定义为终端只能通过移动蜂窝网络的分组域访问策略服务器。
结合图 3说明终端确定业务数据所用网络接入的流程。 假设终端具备同 时接入无线局域网和 WCDMA网络的能力且已经同时接入两个网络。
步骤 301 , 当用户在界面上发起视频通话业务时, 首先触发了接口选择 模块中网络接入的选择功能;
步骤 302 , 接口选择模块查询视频通话业务对应的网络接入优先级策略; 假定 WCDMA网络优先;
步骤 303 , 接口选择模块向接口监测模块查询当前 WCDMA分组链路上 负载情况,如果当前 WCDMA网络分组域链路上实时数据流量与视频通话业 务的缺省流量相加之和大于网络接入所能承担的负载上限, 即超过预置的阔 值, 而优先级策略中次一级的无线局域网链路上的数据流量状况满足视频通 话业务需求, 且无线局域网链路满足视频通话业务对接入网络的要求, 则接 口选择模块为视频通话业务选定无线局域网链路作为业务数据所用的网络接 入; 步骤 304, 接口选择模块确定了业务使用的网络接入后, 比较上一次的 网络接入选择结果,如果发生改变则利用 SIP Publish发布新的网络接入选择。
结合图 4说明终端完成策略五元组设置并启动业务数据交互的流程, 包 括:
步骤 401 , 接口选择模块管理业务配置信息, 如业务缺省流量、 媒体流 对应的端口号和协议名称;
步骤 402, 接口选择模块在为业务选定网络接入后, 为业务配置五元组 中的源 IP地址、 源端口号和协议名称;
视频通话业务涉及音频和视频两类媒体流交互, 接口选择模块在为业务 选定网络接入后, 为业务的两类媒体流, 分别配置一条五元组, 将通话模块 交换获得的无线局域网链路上分配的 IP地址作为五元组的源 IP地址, 端口 号分别设置为业务配置信息中的端口记录, 协议名称字段也根据业务配置信 息中记录来做设置, 本例中音频流和视频流均釆用 UDP协议。
步骤 403 , 接口选择模块利用 SIP Subscribe向策略服务器发起一次对于 业务对端的当前可用网络接入选择的订阅请求;
五元组中的目的 IP地址代表了业务会话对端的网络接入选择。 当业务对 端的用户所在终端也通过 SIP Publish及时发布最新的可用网络接入选择时, 可以认为终端向策略服务器发起订阅后, 得到的网络接入选择通知反映了业 务对端当前最新可用网络接入。 为简化服务器的处理逻辑, 订阅没有有效时 限, 仅单次有效。
步骤 404, 终端在得到业务对端发布的可用网络接入选择后, 即设定视 频会话业务关联的五元组中目的 IP地址, 并根据业务配置信息设置目的端口 号。
至此, 视频会话的通讯两端均根据各自网络接入状况, 实时分配了合适 的网络接入来进行业务交互。 设置路由控制选项, 开始业务数据收发。
