Description
网络通信方法和装置
技术领域
本发明实施例涉及无线通信领域, 尤其涉及一种网络通信方法和装置。 背景技术
随着通信技术的快速发展以及智能用户终端的普及, 用户终端可以支持 多种通信制式的通信系统, 例如无线蜂窝网络、 无线局域网 (Wireless Local Area Networks, WLAN) 、 全球微波互联接入 (Worldwide Interoperability for Microwave Access, WiMAX)、 蓝牙和红外线等其他通信制式, 用户终端可以 根据一定的策略来选择通信制式进行数据通信。具体的制式选择策略有很多, 比较常见的包括: 流量费用最少、 下载速度最快、 电池能耗最小、 默认优先 使用 WLAN等等。
为适应用户终端的多种通信制式或者多种连接的差异化需求, 无线网络 的演进趋势正在加速向无线蜂窝网络与无线局域网络异构融合发展。 现有的 通信网络融合架构由核心网(Core Network , CN)和接入网(Radio Access Network, RAN)两部分构成。 核心网具体由网关 GPRS 支持节点 (Gateway GPRS Support Node, GGSN)/分组数据网关 (Packet Gateway, PGW) 、 GPRS 服务支持节点(Serving GPRS Support Node , SGSN), 服务网关(Serving Gateway , SGW)等网元组成控制面和用户面, 以及归属用户服务器 (Home Subscriber Server, HSS)、 策略与计费规则功能单元 (Policy and Charging Rules Function , PCRF) , 验证、 授权和记账服务器(Authentication Authorization Accounting Server , AAA Server)、 接入网络发现和选择功能单元 (Access Network Discovery and Selection Function , ANDSF)等辅助网元组成用户信息 数据库。接入网既包括基站控制器 (Base Station Controller, BSC) /无线网络控 制器 (Radio Network Controller, RNC)、 基站收发台(Base Transceiver Station, BTS) /基站 NodeB/演进型基站 eNodeB等组成的无线蜂窝网络,也包括 WLAN 接入点 (Access Point, AP)组成的 WLAN网络。 另外还有一种无线蜂窝网络 与 WLAN 网络融合的方案是在 RAN 新增一个无线保真控制器 (Wireless
Fidelity Controller, WIC)。 WIC利用一套自定义的接口与第二代无线蜂窝网 络的 BSC、第三代无线蜂窝网络的 RNC和第四代无线蜂窝网络的移动管理实 体 (Mobility Management Entity, MME)进行通信。
现有技术中无线蜂窝网络与无线局域网络的融合方案都是工作在网络层 及其以上的网络融合方式, 网络融合节点是 GGSN / PGW或 WIC。 将用户终 端和 Internet业务服务器视作用户业务流的两端, 当业务流在 GGSN I PGW 或者 WIC进行无线蜂窝网络与 WLAN网络之间的切换时, 该业务流将会使 用完全不同的互联网协议(Internet Protocol, IP )地址和路由路径, 这样会造 成业务流的中断。 而且, 由于无线蜂窝网络在授权频谱采用资源预留策略, 拥有较好的服务质量(Quality of Service, QoS )保障; 而 WLAN网络在非授 权频谱采用共享竞争策略, 无法提供良好的 QoS保障。 这种由于不同通信制 式对频谱的分配策略导致的 QoS差异会导致切换通信制式后用户体验难以保 持一致性。 综上, 现有技术存在如下的问题: 通信制式切换过程造成业务流 暂时中断并且在切换之后无法保证用户体验的一致性。 发明内容

的终端 1, 可以和不同制式的无线网络接入点 200进行统一的通信。 如图 lc, 所示的系统中, 无线网络接入点 200、 终端 1和终端 2上可以都具有多种制 式控制功能(无线通信控制装置 10) 。 当然, 如图 ld, 无线网络中可以只包 括具有多种制式控制功能 (无线通信控制装置 10) 的终端 1和终端 2 (可以 不具有多种制式控制功能(无线通信控制装置 10) , 只有多制式通信功能) , 终端 1和终端 2可以通过本发明提供的实施方式进行直接的多种制式的无线 通信。
其中,无线通信控制装置 10可以包括两种或两种以上的独立的无线接入 制式的物理层, 并且将它们的数据链路层的传输功能及以上层次的功能进行 融合; 可以将数据链路层的控制功能剥离出来形成独立的融合控制层; 通过 融合控制层与数据链路层之间的接口, 可以实现存储在共享存储区内的用户 数据在多种通信制式之间的无缝传输切换和传输质量的一致性。
参考图 2, 为本发明实施方式中一种无线通信控制装置 10的协议层简单 示意图, 用于说明其工作原理。
图 2所示的无线通信控制装置 10, 包括两种或两种以上相互独立的物理 层, 以支持多种通信制式的无线通信的物理层部分; 多种通信制式的数据链 路层融合成单一的数据链路层; 数据链路层之上有一个融合控制层; 数据链 路层和融合控制层之上都有接口与网络层相连。 其中数据链路层内部可以有 一块高速的共享内存可以同时被多种通信制式的物理层读取和写入。
其中, 图 2中数据链路层支持多种通信制式, 多种通信制式包括但不限 于: 无线蜂窝网络、 无线局域网 WLAN、 全球微波互联接入 WiMAX、 蓝牙 以及红外线。
示例性的, 上述图 2中的物理层可以是芯片或者单板等硬件模块, 融合 控制层可以是独立的控制网元 (参考图 3 ) , 或者为软件, 与图 2中数据链 路层结合, 网络层可以是运行在 CPU 的传输控制协议 /因特网互联协议 (Transmission Control Protocol/Internet Protocol, TCP/IP)协议。 图 2中数据链 路层支持多种通信制式具体是指运行在同一个物理实体上的、 不同的通信协 议所规定的各项控制面功能和数据面功能的软件和硬件模块。 具体的, 多种 通信制式的数据链路层融合之后得到的新的数据链路层可以是在一个通信单 板上 (通常是多核处理器架构) 同时运行着一组软件程序, 在程序组中的部
分程序对应于第一通信制式的独有的数据链路层功能, 部分程序对应于第二 通信制式的独有的数据链路层功能, 部分程序对应于第一通信制式和第二通 信制式的公有的数据链路层功能, 其中, 第一通信制式或第二通信制式是多 种通信制式中的不同的通信制式。以长期演进(Long Term Evolution, LTE) 时 分双工 (Time Division Duplexing, TDD)通信制式和 WLAN通信制式为例, 它们两者的数据链路层功能大约有 30%左右是可以公用的, 例如速率自适应 功能, 拆组包功能, 乱序重排功能, 等等。 值得注意的是那些公有的数据链 路层功能在处理不同的通信制式的数据时采用的系统参数是不同的。 融合之 后的新的数据链路层的可以是将不同的通信制式的数据链路层视作一个更大 的、 更宏观的数据链路层之和, 剔除不同的通信制式之间重复的功能, 并且 在这些数据链路层之上封装一层统一的对外接口。对于更高层或更低层而言, 它们看到的是只有统一接口的新的数据链路层, 而不再区分究竟对应于哪一 种通信制式的数据链路层。 统一接口之下的不同的通信制式的数据链路层之 间的协调工作则由无线通信控制装置 10 (图 2所示的融合控制层)负责调度。
需要说明的是, 本发明实施例中表述的数据链路层是指多种通信制式的 数据链路层融合之后得到的新的数据链路层, 为了简化表述, 下文中的数据 链路层如无特殊说明均为前述融合后得到的新的数据链路层。
参考图 3, 为无线通信控制装置 10的一个实施方式的示意图, 以无线蜂 窝网络制式和 WLAN制式为例, 融合控制层在物理上是独立的, 可以与图 3 中的数据链路层和网络层分别通信, 其中多种制式融合后的数据链路层中包 括: 寻呼信道 (Paging Channel , PCH)、广播信道 (Broadcast Channel, BCH)、 随机接入信道 (Random Access Channel, RACH)、 下行共享信道 (Downlink Shared Channel, DL-SCH)、 上行共享信道 (Uplink Shared Channel, UL-SCH) 以及载波侦听多路访问 /冲突避免(Carrier Sense Multiple Access with Collision Avoidance, CSMA/CA) ; 无线蜂窝网络制式的物理层包括: 物理广 播信道 (Physical Broadcast Channel , PBCH)、 物理随机接入信道 (Physical Random Access Channel , PRACH)、 物理下行共享信道 (Physical Downlink Shared Channel Packet Data Channel, PDSCH)以及物理上行共享信道 (Physical Uplink Shared Channel, PUSCH)。

若吞吐量或缓存队列长度或入网认证用户个数大于对应的预设阈值, 则 确定需要使用其他的通信制式来传输用户的数据。
示例性的, 监测单元 11 监测到的无线蜂窝网络的入网认证用户个数为 110, 大于预设的阈值 100, 则可以确定无线蜂窝网络的承载超出了负荷, 用 户数据将不能被及时的发送给用户终端, 因此, 需要选择使用 WLAN来发送 用户数据。
可选的, 选择单元 13具体用于:
选择除了当前使用的通信制式外的其他的通信制式中的任一种通信制式 来传输用户的数据; 或者
选择除了当前使用的通信制式外的其他的通信制式中的至少两种通信制 式按照预设比例同时来传输用户的数据; 或者
选择当前使用的制式和其他的通信制式中至少一种通信制式按照预设比 例同时来传输用户的数据。
示例性的, 无线蜂窝网络承载超出负荷, 可以选择使用 WLAN发送用户 的数据; 或者可以选择 WLAN和 WiMAX两种制式同时传输用户的数据, 其 中两种制式按照规定的比例来传输用户的数据 (例如可以两种制式各承担 50%的用户数据) ; 或者还可以选择无线蜂窝网络、 WLAN以及 WiMAX三 种制式同时传输用户的数据, 其中三种制式按照规定的比例来传输用户的数 据(例如,无线蜂窝网络承担 20%的用户数据、 WLAN承担 50%的用户数据、 WiMAX承担剩余的 30%的用户数据) 。 选择多种通信制式传输用户的数据 时, 多种通信制式可以按照比例来发送用户数据, 每种制式承担的比例根据 实际需要在 0%〜100%之间选择, 这样可以合理使用多种通信制式, 提高传 输数据的效率, 改善用户体验。
可选的, 匹配单元 14具体用于:
根据选择的通信制式对应的系统参数对用户的数据进行不同通信制式间 的包长匹配、 服务质量匹配 (包括速率匹配) 、 或安全匹配。
其中, 包长匹配是指第二制式 (例如 WLAN) 将来自第一制式 (例如无 线蜂窝网络) 的待传输数据包拆分或者组合为符合第二制式的, 并具有新长 度和格式的数据包。
示例性的, 包长匹配的具体实现时分为发送数据和接收数据两种情况: 发送数据的情况, 包长匹配包括: 无线通信控制装置 10在第一通信制式 下从网络层获取待发送的第一数据包; 在数据链路层, 根据第一通信制式的 第一系统参数将第一数据包拆分成第一通信制式对应的物理层所需的包长 度, 得到若干个第二数据包; 如果判断需要由第二通信制式继续第二数据包 的发送过程; 在数据链路层, 根据第二通信制式的第二系统参数将第二数据 包组装或拆分成第二通信制式对应的物理层所需的包长度, 得到若干个第三
数据包; 通过数据链路层, 将第三数据包发送至第二通信制式的物理层, 由 物理层中的发送机完成数据包的发送。
接收数据的情况, 包长匹配包括: 无线通信控制装置 10在第一通信制式 下从物理层的无线信道收到第四数据包; 在数据链路层, 将来自第一通信制 式的物理层的第四数据包根据第一通信制式对应的第一系统参数组装成第一 通信制式对应的第五数据包; 如果判断需要由第二通信制式继续第五数据包 的接收过程; 在数据链路层, 根据第二通信制式的第二系统参数将第五数据 包组装或拆分成第二通信制式对应的网络层所需的包长度, 得到若干的第六 数据包; 通过数据链路层, 将第六数据包发送至网络层。
服务质量 QoS匹配是指第一制式(例如无线蜂窝网络)告知第二制式(例 如 WLAN) 用户在第一制式下的服务质量要求参数, 第二制式按照第一制式 下的服务质量要求参数为用户提供服务。 其中, 服务质量要求参数包括但不 局限于: 速率、 时延或者抖动。
示例性的, 已知不同的通信制式分别定义了不同的 QoS等级。 例如, 第 三代合作伙伴计划 (The 3rd Generation Partnership Project, 3GPP) 的 LTE定 义的 8级 QoS等级, 从 Level 0到 Level 7优先级逐歩递减; WLAN定义的 4级 QoS等级, 从 Voice (ACO) -> Video (ACl) -> Best Effort (AC2) -> Background (AC3)优先级逐歩递减。
QoS 匹配包括: 网络拥有者或网络运营商实现定义不同的通信制式之间 不同的 QoS等级之间的映射关系,例如 3GPP Level 0和 Level 1约等于 WLAN 的 Voice (ACO); 无线通信控制装置 10在第一通信制式从网络层获取待发送 的第一数据包; 在数据链路层为第一数据包确定采用第一通信制式下的第一 服务质量等级; 在数据链路层, 根据第一通信制式的第一系统参数将第一数 据包拆分成第一通信制式对应的物理层所需的包长度, 得到若干个第二数据 包; 如果判断需要由第二通信制式继续第二数据包的发送过程; 在数据链路 层将第一通信制式下的第一服务质量等级映射为第二通信制式下的第二服务 质量等级; 通过数据链路层使物理层的发送机按照第二服务质量等级发送数 据包。
更为具体的, 上述 QoS匹配中的速率匹配是指第一制式 (例如无线蜂窝 网络) 告知第二制式 (例如 WLAN) 用户在第一制式下的数据需求速率和实
际速率, 第二制式根据自身承载能力为用户提供接近第一制式下的数据需求 速率的速率。
示例性的, 速率匹配包括: 在第一通信制式下, 无线通信控制装置 10从 网络层获取待发送的第一数据包; 在数据链路层, 为第一数据包确定采用第 一通信制式下的第一系统参数所决定的第一编码调制方式和第一多天线空间 流方式, 即第一发送速率; 在数据链路层, 根据第一通信制式的第一系统参 数将第一数据包拆分成第一通信制式对应的物理层所需的包长度, 得到若干 个第二数据包; 如果判断需要由第二通信制式继续第二数据包的发送过程; 在数据链路层, 从第二通信制式下的第二系统参数中挑选出最接近第一发送 速率的第二发送速率; 在数据链路层, 根据第二发送速率映射得到后续发送 第二数据包的第二编码调制方式和第二多天线空间流方式;通过数据链路层, 将第二编码调制方式和第二多天线空间流方式通知第二通信制式对应的物理 层, 由物理层的发送机完成数据包的发送。
安全匹配是指第一制式 (例如无线蜂窝网络)告知第二制式 (例如 WLAN) 用户在第一制式的安全等级, 第二制式按照第一制式下的安全等级为用户提 供服务, 并且反馈第一制式。 如果第二制式为用户提供服务时的安全等级不 能达到第一制式的安全等级则不使用第二制式为用户提供服务。
示例性的, 安全匹配包括: 由网络拥有者或网络运营者定义不同的通信 制式之间不同的安全等级之间的映射关系;无线通信控制装置 10在第一通信 制式以第一安全等级为用户提供通信服务; 如果判断需要从第一制式切换到 第二制式为用户提供通信服务, 在数据链路层检査第二通信制式是否能够提 供不低于第一通信制式下的第一安全等级的第二通信制式下的第二安全等 级, 如果能提供, 则进行切换; 如果不能提供, 则不进行切换。
可选的, 匹配单元 14还可以具体用于:
若选择的其他通信制式中的通信制式中有属于采用频谱资源预留策略的 第一类通信制式的通信制式, 则需要向选择的属于第一类通信制式的通信制 式的资源管理器申请传输资源, 申请到传输资源后对用户的数据进行参数匹 配;其中,第一类通信制式包括:无线蜂窝网络和全球微波互联接入 WiMAX。
示例性的, 假设判断单元 12判断 WLAN承载超出负荷, 需要选择使用 无线蜂窝网络来发送用户数据, 因为无线蜂窝网络采用频谱资源预留策略,
需要先向无线蜂窝网络的资源管理器申请传输资源, 申请到传输资源后对用 户的全部或部分数据进行不同通信制式间的包长匹配、 速率匹配、 服务质量 匹配以及安全匹配。
可选的, 如图 5所示, 该无线通信控制装置 10还包括:
接收单元 16,用于接收确认反馈消息 ACK或者非确认反馈消息 NACK, 确认反馈消息是数据接收端在确认正确接收到数据以后发送的消息, 非确认 反馈消息是数据接收端在确认未正确接收到数据以后发送的消息。
示例性的, 如果是网络侧向用户终端发送数据, 用户终端在正确接收到 数据后会发送确认反馈消息 ACK给无线通信控制装置 10以便于无线通信控 制装置 10确认数据发送成功,用户终端在未正确接收到数据时会向无线通信 控制装置 10发送非确认反馈消息 NACK以便于无线通信控制装置 10确认数 据未发送成功需要指示数据链路层以及物理层重新发送数据给用户终端, 另 夕卜, 如果无线通信控制装置 10在预设的时间内既没有收到 ACK也未收到 NACK, 则认为超时 (Timeout), 需要指示数据链路层以及物理层重新发送数 据给用户终端。
需要说明的是,本发明实施例提供的无线通信控制装置 10基于数据链路 层执行相应的功能, 相比现有技术中的多种通信制式网络切换发生在网络层 能够对链路状态的动态响应更加灵敏, 并且在本发明实施例中数据交换在数 据链路层数据,而不是现有技术的 IP会话重新建立、 IP重路由、 IP转向发送、 IP头重新解析, 因此, 业务数据的性能抖动时间更短, 可以保证多种通信制 式下网络的无缝切换以及用户体验的一致性。
还需指出的是, 参考图 la-ld, 本发明实施例还提出了包含无线通信控制 装置 10的网络侧的基站或者接入点(名称不限), 或者终端, 例如智能手机、 平板电脑以及便携式计算机等。
此外, 各个实施例提到的终端也可以称为系统、 用户单元、 用户站、 移 动站、 移动台、 远方站、 远程终端、 移动设备、 用户终端、 终端、 无线通信 设备、 用户代理、 用户装置或 UE (User Equipment, 用户设备) 。 终端可以 是蜂窝电话、 无绳电话、 SIP ( Session Initiation Protocol, 会话启动协议) 电 话、 WLL (Wireless Local Loop, 无线本地环路) 站、 PDA (Personal Digital Assistant, 个人数字处理)、 具有无线通信功能的手持设备、 计算设备或连接
到无线调制解调器的其它处理设备。 其也可以是车载设备或者可穿戴设备。 本发明实施例提供的无线通信控制装置, 首先监测数据链路层所支持的 多种通信制式各自对应的链路性能参数, 然后根据当前使用的通信制式对应 的链路性能参数判断是否需要使用其他的通信制式来传输用户的数据, 若需 要使用其他的通信制式, 则选择传输用户的数据要使用的通信制式, 再根据 选择的通信制式对应的系统参数对用户的数据进行参数匹配, 最后通过数据 链路层以及物理层传输参数匹配后的数据。 这样, 能够使用不同的通信制式 给用户提供业务服务, 可以避免用户终端的业务流暂时中断, 同时保证用户 体验的一致性; 通信系统整体效率更高。
进一歩的, 通过上述各实施方式可以看到, 无线通信控制装置 10中的控 制功能位于数据链路层, 而不是 IP层。 这样, 可以对链路状态的动态响应更 加灵敏, 因而针对不同制式之间的切换决策可以更快。
另外, 通过上述实施方式可以看到, 对于数据交换过程, 在数据链路层 包括数据存储区, 而不需要在 IP层进行处理, 因而不需要 IP会话重新建立、 IP重路由、 IP转向发送以及 IP头重新解析等等过程。所以, 采用本发明的实 施方式后, 业务数据的性能抖动时间更短, 换言之, 在不同制式之间进行无 线通信切换的过程可以更快。

为了使本领域技术人员能够更清楚地理解本发明实施例提供的技术方 案, 下面通过具体的实施例, 对本发明的实施例提供的网络通信方法进行详 细说明, 如图 7所示, 该方法包括:
歩骤 201、 监测数据链路层所支持的多种通信制式各自对应的链路性能 参数。
其中, 数据链路层支持多种通信制式, 多种通信制式包括: 无线蜂窝网 络、 无线局域网 WLAN、 全球微波互联接入 WiMAX、 蓝牙以及红外线。
具体的, 该数据链路层如图 2以及前文所述, 是由多种通信制式的数据 链路层融合得到的, 同时运行多种通信制式的通信协议, 其细节不再赘述。 一种通信制式的链路性能参数可以包括: 吞吐量、 缓存队列长度以及入网认 证用户个数之一或者组合。
歩骤 202、 根据当前使用的通信制式对应的链路性能参数判断是否需要 使用其他的通信制式来传输用户的数据。
具体的, 将当前使用的通信制式的吞吐量或缓存队列长度或入网认证用 户个数分别与对应的预设阈值比较;
若吞吐量或缓存队列长度或入网认证用户个数大于对应的预设阈值, 则 确定需要使用不同的通信制式来传输用户的全部或部分数据。
示例性的, 若监测到的无线蜂窝网络的入网认证用户个数为 110, 大于 预设的阈值 100, 则可以确定无线蜂窝网络的承载超出了负荷, 用户数据将 不能被及时的发送给用户终端,因此,需要选择使用 WLAN来发送用户数据。
歩骤 203、 若需要使用其他的通信制式, 则选择传输用户的数据要使用 的通信制式。
选择除了当前使用的通信制式外的其他的通信制式中的任一种通信制式 来传输用户的数据; 或者
选择除了当前使用的通信制式外的其他的通信制式中的至少两种通信制 式按照预设比例同时来传输用户的数据; 或者
选择当前使用的制式和其他的通信制式中至少一种通信制式按照预设比 例同时来传输用户的数据。
示例性的, 无线蜂窝网络承载超出负荷, 可以选择使用 WLAN发送用户 的数据; 或者可以选择 WLAN和 WiMAX两种制式同时传输用户的数据, 其 中两种制式按照规定的比例来传输用户的数据 (例如可以两种制式各承担 50%的用户数据) ; 或者还可以选择无线蜂窝网络、 WLAN以及 WiMAX三 种制式同时传输用户的数据, 其中三种制式按照规定的比例来传输用户的数 据(例如,无线蜂窝网络承担 20%的用户数据、 WLAN承担 50%的用户数据、 WiMAX承担剩余的 30%的用户数据) 。 选择多种通信制式传输用户的数据 时, 多种通信制式可以按照比例来发送用户数据, 每种制式承担的比例根据 实际需要在 0%〜100%之间选择, 这样可以合理使用多种通信制式, 提高传 输数据的效率, 改善用户体验。
歩骤 204、 若选择的其他通信制式中的通信制式中有属于采用频谱资源 预留策略的第一类通信制式的通信制式, 则需要向选择的属于第一类通信制 式的通信制式的资源管理器申请传输资源。
其中,第一类通信制式包括:无线蜂窝网络和全球微波互联接入 WiMAX。 示例性的, 假设判断 WLAN承载超出负荷, 需要选择使用无线蜂窝网络 来发送用户数据, 因为无线蜂窝网络采用频谱资源预留策略, 需要先向无线 蜂窝网络的资源管理器申请传输资源, 申请到传输资源才能利用申请到传输 资源传输数据。
歩骤 205、 根据选择的通信制式对应的系统参数对用户的数据进行参数 匹配。
具体的, 参数匹配包括但不限于: 包长匹配、 速率匹配、 服务质量匹配 或者安全匹配。上述参数匹配的细节可以参考前述匹配单元 14的描述, 此处 不再赘述。

示例性的, 在数据链路层对数据进行拆组包、 速率自适应以及分配传输 信道后将数据转发到物理层, 然后通过物理层将数据发送出去。
歩骤 207、 接收确认反馈消息 ACK或者非确认反馈消息 NACK。
其中, 确认反馈消息是数据接收端在确认正确接收到数据以后发送的消 息,非确认反馈消息是数据接收端在确认未正确接收到数据以后发送的消息。
示例性的,如果是无线通信控制装置 10所在的网络侧向用户终端发送数
据,用户终端在正确接收到数据后会发送确认反馈消息 ACK给无线通信控制 装置 10以便于无线通信控制装置 10确认数据发送成功, 用户终端在未正确 接收到数据时会向无线通信控制装置 10发送非确认反馈消息 NACK以便于 无线通信控制装置 10 确认数据未发送成功需要指示数据链路层以及物理层 重新发送数据给用户终端, 另外, 如果无线通信控制装置 10在预设的时间内 既没有收到 ACK也未收到 NACK, 则认为超时 (Timeout), 需要指示数据链 路层以及物理层重新发送数据给用户终端。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的技术方 案, 下面通过具体的实施例, 对上述本发明的实施例提供的多种通信制式的 网络通信方法进行举例详细说明, 为了方便阐述, 将多种通信制式简化为无 线蜂窝网络与 WLAN这两种制式, 链路性能参数以吞吐量为例:

参考图 9, 无线通信控制装置 10包括融合控制模块, WLAN制式模块, 无线蜂窝网络制式模块 (本领域技术人员知道上述模块为从功能上的划分以 便于清晰的描述方案)。 融合控制模块监测无线蜂窝网络制式与 WLAN制式 的吞吐量, 判断 WLAN制式的吞吐量超过了设定的阈值, 则选择使用无线蜂 窝网络制式来传输用户的部分数据 (实际中按照设定的规则划分用户的数据 经由哪种通信制式按比例传输) , 因为无线蜂窝网络制式采用的是频谱资源 预留策略, 在传输数据前需要先向无线蜂窝网络的资源管理器申请传输的资 源, 申请到传输资源后, 对经由无线蜂窝网络制式传输的数据进行 WLAN制 式与无线蜂窝网络制式之间的参数匹配, 然后该部分数据在数据链路层完成 封包处理、 信道分配等处理后由物理层的发送机将该部分数据发送给接收设
备。
本发明实施例提供的网络通信方法, 首先监测数据链路层所支持的多 种通信制式各自对应的链路性能参数, 然后根据当前使用的通信制式对应 的链路性能参数判断是否需要使用其他的通信制式来传输用户的数据, 若 需要使用其他的通信制式, 则选择传输用户的数据要使用的通信制式, 再 根据选择的通信制式对应的系统参数对用户的数据进行参数匹配, 最后通 过数据链路层以及物理层传输参数匹配后的数据。 这样, 能够使用不同的 通信制式给用户提供业务服务, 可以避免用户终端的业务流暂时中断, 同 时保证用户体验的一致性; 通信系统整体效率更高。
