Description

一种异构网络中的接入方法和装置
本申请要求在2014年08月08日提交中国专利局、申请号为201410389810.0、发明名称为“一种异构网络中的接入方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，特别涉及一种异构网络中的接入方法和装置。
背景技术
随着新的无线接入技术(Radio Access Technology，RAT)的不断涌现，如蜂窝网接入技术、无线保真(Wireless Fidelity，WiFi)接入技术等，出现了多种无线接入技术共存的无线通信网络格局。目前，有多家网络运营商为用户提供服务，从用户的角度来看，由于垄断和相互排斥，以及用户终端的单模特性，网络运营商的市场份额是相互独立的。随着多模终端的出现，网络运营商的市场份额在用户层面上有交叉，携号转网政策的出台也允许了网络运营商市场之间的相互转化。
从业务的角度来看，目前，用户的同一个业务仍只是选择一家运营商，根据业务流量和网络承载量，运营商可能会用自身的WiFi网络分担3G网络的流量，但是不同的运营商之间在同一项业务上是不存在合作关系的，这在很大程度上限制了用户选择的自由，尤其是对移动性较强的车载终端。此外，网络运营商一般采用固定的收费规则，即使采用不同服务对应不同收费的套餐模式，也不能让每个用户按照自己的意愿选择付费和对应的服务质量。
网络服务未来的趋势应该是动态的定价模式，不同的运营商之间可能同时为一项业务提供不同的接入服务，在合作的同时竞争流量。这样，对于用户来说，可以按照自己的需求自由选择；对于运营商来说，竞争更细化使得运营商的服务也会更加完善，运营商也可以避免重复建设，减少部署成本，同时也扩大了对市场的占有。
综上所述，在异构无线网络的网络选择方面，现有方案侧重于用户(业务)的实际需求，为用户(业务)的实际需求选择一个最合适的接入网络，使得用户(业务)在任一时刻，只能享受到一个网络的服务，而不能同时得到不同网络的服务，从而限制了用户选择的自由，降低了用户体验。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，本发明的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)等。
还应理解，在本发明实施例中，用户设备(UE，User Equipment)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中，基站(例如，接入点)可以是指接入网中在空中接口上通过一个 或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本发明并不限定。
本发明基于各接入点需要为用户设备提供的接入速率和该接入点当前能够提供的接入速率，为用户设备选择多个接入点进行接入，实现了各运营商在不浪费已有通信基础设施的前提条件下，对于用户采用多种接入技术进行合作竞争。
下面结合说明书附图对本发明实施例作进一步详细描述。应当理解，此处所描述的实施例仅用于说明和解释本发明，并不用于限定本发明。
为了使不同的运营商同时为一项业务提供不同的接入服务，以满足用户可以按照自己的需求自由选择接入点，首要的是建立一种可实施的竞争机制，这种流量的竞争在用户设备看来就是选择接入点和接入速率，也就是异构网络流量竞争问题。本发明实施例提供了这样一种异构网络流量竞争的方案，在运营商采用动态定价进行合作竞争的前提下，将竞争的粒度细化到流量，突破现有研究中一项业务在同一时刻只能由一家运营商服务的模式，打破运营商间互联互通的障碍，由于建立了网络多径路由与流量分配的模型，使用户设备可以选择不同的接入方式，为网络的发展提供新的流量运营模式，尤其适用于移动速度高的车联网系统。
本发明实施例提供的第一种异构网络中的接入方法，如图1所示，该方法包括如下步骤：
步骤11、将能够为用户设备提供服务的接入点划分为至少一个竞争组。
本步骤中，将能够为用户设备提供服务的接入点划分为至少一个组，每个组称为一个竞争组，每个竞争组中包含至少一个能够为用户设备提供服务的接入点。
步骤12、确定竞争组的接入开销，并根据确定出的接入开销，从竞争组中，为用户设备选择一个目标竞争组进行接入。
本步骤中，根据确定出的接入开销，从竞争组中，为用户设备选择一个竞争组进行接入，所选择的竞争组定义为目标竞争组，用户设备可以接入目标竞争组中的每个接入点。
本发明实施例中，先将能够为用户设备提供服务的接入点划分为至少一个竞争组；再确定竞争组的接入开销，并根据确定出的接入开销，从竞争组中，为用户设备选择一个目标竞争组进行接入，从而提供了一种异构网络流量竞争的方案，突破现有研究中一项业务在同一时刻只能由一家运营商服务的模式，并使用户设备可以选择不同的接入方式，为网络的发展提供新的流量运营模式。
在实施中，在步骤11之前，该方法还包括：建立异构网络模型，即确定异构网络中能够为用户设备提供服务的接入点。
以车联网系统为例，车联网系统中，车载终端可能同时处于蜂窝网络、WiFi网络以及无线自组织(ad hoc)网络的异构网络中。从功能而言，三种网络互为补充，各有优势。从网络结构看，车辆间组成的ad hoc网络可以理解为无线接入网的补充，可以将网络模型中将ad hoc网络中的某些节点看作是接入点，而这些节点又可以作为无线接入点的转发节点。建立异构网络模型即从蜂窝网络、WiFi网络以及无线ad hoc网络的异构网络中，确定出能够为车载终端提供服务的接入点。
较佳地，步骤11中进行划分的接入点，可以是该异构网络中能够为用户设备提供服务的所有接入点，也可以是该异构网络中能够为用户设备提供服务的接入点的一个子集。
举例说明，以车联网系统为例，假设车载终端S目前所在ad hoc网络中有两个车载终端可以为该车载终端S提供中间接入服务，即该车载终端S可以通过这两个车载终端连接到接入点1和接入点2，将这两个车载终端记为中间节点1和中间节点2，同时，车载终端S还可以接入运营商A的3G接入点3和接入点4，运营商A的WiFi接入点5和接入点6，运营商B的3G接入点7和接入点8，运营商B的WiFi接入点9和接入点10。则对车载终端S所建立的车联网异构网络模型记为网络G，可以如图2所示，也可以是图2中包含车载终端S的任一子图。
又如，车载终端S目前所在ad hoc网络中有两个车载终端可以直接提供服务，记为接入点1和接入点2，即车载终端S可以通过这两个车载设备直接连接到接入网络，同时，车载终端S还可以接入运营商A的3G接入点3和接入点4，运营商A的WiFi接入点5和接入点6，运营商B的3G接入点7和接入点8，运营商B的WiFi接入点9和接入点10。则对车载终端S所建立的车联网异构网络模型记为网络G，可以如图3所示，也可以是图3中包含车载终端S的任一子图。
在实施中，步骤11中，将能够为用户设备提供服务的接入点划分为至少一个竞争组，包括但不限于以下几种优选方式：
根据归属于同一运营商的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，归属于同一运营商的每个接入点被划分在不同的竞争组；或者
根据归属于同一运营商的同一接入技术的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，归属于同一运营商的同一接入技术的每个接入点被划分在不同的竞争组；或者
根据设定距离范围内的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，设定距离范围内的每个接入点被划分在不同的竞争组；或者
根据属于同一接入技术的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，属于同一接入技术的接入点被划分在不同的竞争组；
或者
根据当前能够提供的接入速率之间差值超过给定阈值的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，当前能够提供的接入速率差值超过给定阈值的接入点被划分在不同的竞争组；
或者
根据当前能够提供的接入速率与给定接入速率参考值的差值满足给定阈值范围的接入点必须竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，当前能够提供的接入速率与给定接入速率参考值的差值满足给定阈值范围的接入点被划分在相同的竞争组；
或者
将能够为用户设备提供服务的接入点随机划分为至少一个竞争组。
除了上述列举的几种优选划分方式，还可以采用其他方式将能够为用户设备提供服务的接入点划分为至少一个竞争组，本发明不对划分方式进行限定。
在实施中，步骤12中，确定竞争组的接入开销，包括：
根据竞争组的单位信息的收益与该竞争组中每个接入点需要为用户设备提供的接入速率，确定每个竞争组的接入开销。
具体的，根据竞争组的单位信息的收益与该竞争组中每个接入点需要为用户设备提供的接入速率，确定步骤11中所划分的至少一个竞争组中的每个竞争组的接入开销。
其中，针对每个竞争组，分别确定该竞争组中每个接入点需要为用户设备提供的接入速率，包括：
针对每个竞争组，按照该竞争组中的各接入点的纯收益最大原则，分别确定出该竞争组中每个接入点需要为用户设备提供的接入速率。
作为一种优选的实现方式，针对每个竞争组，可以建立微分博弈模型，以求解每个竞争组的单位信息的收益和该竞争组中每个接入点需要为用户设备提供的接入速率。微分博弈模型包括多种具体实现方式，主要思想如下：
微分博弈中包括n个参与者(即接入点)，微分博弈模型包括两个部分：一部分是参与竞争的接入点的最大纯收益的表达式，接入点的纯收益等于毛收益减去接入点的成本，如果是ad hoc网络中的接入点，则接入点的毛收益还要考虑与其它节点的分摊；另一部分体现的是各接入点采取的竞争策略之间的相互影响，即接入点提供的接入速率与单位信息的收益之间的关系。通过对上述微分博弈模型求解，可计算出每个竞争组的单位信息的收益和该竞争组中每个接入点需要为用户设备提供的接入速率。
较佳地，针对每个竞争组，按照以下微分博弈模型，分别确定出该竞争组的单位信息的收益和该竞争组中每个接入点需要为用户设备提供的接入速率：

本步骤中，将能够为用户设备提供服务的接入点划分为至少一个组，每个组称为一个 竞争组，每个竞争组中包含至少一个能够为用户设备提供服务的接入点。
步骤42、针对每个竞争组，分别确定该竞争组中每个接入点需要为用户设备提供的接入速率，并在该竞争组中每个接入点当前能够提供的接入速率均不小于自身需要为用户设备提供的接入速率时，将该竞争组确定为预选竞争组；
本步骤中，先对步骤11划分出的竞争组进行筛选，将满足条件(即该竞争组中每个接入点当前能够提供的接入速率均不小于自身需要为用户设备提供的接入速率)的竞争组确定为预选竞争组，以提高处理效率。
步骤43、确定每个预选竞争组的接入开销，并根据确定出的接入开销，从预选竞争组中，为用户设备选择一个目标竞争组进行接入。
本步骤中，根据确定出的接入开销，从预选竞争组中，为用户设备选择一个预选竞争组进行接入，所选择的预选竞争组定义为目标竞争组，用户设备可以接入目标竞争组中的每个接入点。
本发明实施例中，先将能够为用户设备提供服务的接入点划分为多个竞争组；再针对每个竞争组，确定该竞争组中每个接入点需要为用户设备提供的接入速率，并在该竞争组中每个接入点当前能够提供的接入速率均不小于自身需要为用户设备提供的接入速率时，将该竞争组确定为预选竞争组；最后确定每个预选竞争组的接入开销，并根据确定出的接入开销，从预选竞争组中，为用户设备选择一个目标竞争组进行接入，从而提供了一种异构网络流量竞争的方案，突破现有研究中一项业务在同一时刻只能由一家运营商服务的模式，并使用户设备可以选择不同的接入方式，为网络的发展提供新的流量运营模式。
在实施中，在步骤41之前，该方法还包括：建立异构网络模型，即确定异构网络中能够为用户设备提供服务的接入点。具体建立异构网络模型的过程参见上述第一种异构网络中的接入方法中的内容，此处不再赘述。
较佳地，步骤41中进行划分的接入点，可以是该异构网络中能够为用户设备提供服务的所有接入点，也可以是该异构网络中能够为用户设备提供服务的接入点的一个子集。
在实施中，步骤41中，将能够为用户设备提供服务的接入点划分为至少一个竞争组，包括但不限于以下几种优选方式：
根据归属于同一运营商的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，归属于同一运营商的每个接入点被划分在不同的竞争组；或者
根据归属于同一运营商的同一接入技术的接入点不竞争的原则，将能够为用户设备提供服务的接入点划分为至少一个竞争组，其中，归属于同一运营商的同一接入技术的每个接入点被划分在不同的竞争组；或者

或者
将能够为用户设备提供服务的接入点随机划分为至少一个竞争组。
除了上述列举的几种优选划分方式，还可以采用其他方式将能够为用户设备提供服务的接入点划分为至少一个竞争组，本发明不对划分方式进行限定。
在实施中，步骤42还包括：针对每个竞争组，若该竞争组中至少一个接入点当前能够提供的接入速率小于自身需要为用户设备提供的接入速率时，放弃该竞争组。
具体的，针对每个竞争组，根据各接入点的网络负荷情况，实时检测该竞争组中每个接入点当前能够提供的接入速率，若该竞争组中每个接入点当前能够提供的接入速率都不小于该接入点需要为用户设备提供的接入速率，则将该竞争组确定为预选竞争组，并计算该预选竞争组的接入开销；否则，即若该竞争组中至少一个接入点当前的能够提供的接入速率小于该接入点需要为用户设备提供的接入速率，则放弃该竞争组。

作为一种优选的实现方式，针对每个竞争组，可以建立微分博弈模型，以求解每个竞争组中每个接入点需要为用户设备提供的接入速率。微分博弈模型包括多种具体实现方式，主要思想如下：
微分博弈中包括n个参与者(即接入点)，微分博弈模型包括两个部分：一部分是参与竞争的接入点的最大纯收益的表达式，接入点的纯收益等于毛收益减去接入点的成本，如果是ad hoc网络中的接入点，则接入点的毛收益还要考虑与其它节点的分摊；另一部分 体现的是各接入点采取的竞争策略之间的相互影响，即接入点提供的接入速率与单位信息的收益之间的关系。通过对上述微分博弈模型求解，可计算出每个竞争组的单位信息的收益和该竞争组中每个接入点需要为用户设备提供的接入速率。
较佳地，针对每个竞争组，按照上述公式一所示的微分博弈模型，分别确定出该竞争组中每个接入点需要为用户设备提供的接入速率。具体求解过程参见上述第一种异构网络中的接入方法中的内容，此处不再赘述。

较佳地，按照上述公式二，确定每个预选竞争组的接入开销，具体求解过程参见上述第一种异构网络中的接入方法中的内容，此处不再赘述。
基于上述任一实施例，步骤43中，根据确定出的接入开销，从预选竞争组中，为用户设备选择一个目标竞争组进行接入，还包括：
根据用户设备对接入网络的网络质量的需求，从预选竞争组中，为用户设备选择一个目标竞争组进行接入。
其中，用户设备对接入网络的网络质量的需求包括但不限于以下需求中的一种或多种：

用户设备对接入网络的抖动需求，如接入网络的抖动小于设定的阈值等；
用户设备对接入网络的丢包率需求，如接入网络的丢包率小于设定的阈值等。
具体的，步骤43中，根据确定出的每个预选竞争组的接入开销，从预选竞争组中，为用户设备选择一个目标竞争组进行接入时，可以仅依据每个预选竞争组的接入开销，选择满足设定接入开销条件的预选竞争组作为目标竞争组；也可以依据每个预选竞争组的接入开销和用户设备对接入网络的网络质量的需求，将同时满足设定接入开销条件和用户设备对接入网络的网络质量的需求的预选竞争组确定为目标竞争组。
其中，设定的接入开销条件可以为：接入开销最小、或者接入开销小于设定阈值、或者在设定的阈值范围内等等)。若至少两个竞争组均满足设定的接入开销条件，则可以从该至少两个竞争组中，随机选择一个竞争组作为目标竞争组。
需要说明的是，本发明实施例中所涉及的接入速率也可理解为频谱资源的其他量化指标，如带宽等，即接入点当前能够提供的接入速率可理解为接入点当前能够提供的带宽，接入点需要为用户设备提供的接入速率可理解为接入点需要为用户设备提供的带宽。
下面以车联网系统为例，结合以下具体实施例，对本发明提供的异构网络中的接入方 法进行说明。
实施例一、本实施例的处理过程如图5所示，包括如下步骤：
步骤51：网络建模，确定出网络中能够为用户设备提供服务的接入点。
步骤52：将确定出的接入点划分为多个竞争组。
以图3所示的网络模型为例，假设本步骤中基于同一家运营商的同一种接入技术之间不竞争的原则进行竞争组的划分，则接入点可划分为16组竞争组，每个竞争组包含6个接入点，分别是(1,2,3,5,7,9)，(1,2,3,5,7,10)，(1,2,3,5,8,9)，(1,2,3,5,8,10)，(1,2,3,6,7,9)，(1,2,3,6,7,10)，(1,2,3,6,8,9)，(1,2,3,6,8,10)，(1,2,4,5,7,9)，(1,2,4,5,7,10)，(1,2,4,5,8,9)，(1,2,4,5,8,10)，(1,2,4,6,7,9)，(1,2,4,6,7,10)，(1,2,4,6,8,9)，(1,2,4,6,8,10)。
步骤53：微分博弈建模。
具体的，在某个竞争组中，有n个参与者(接入点)，记为V1,V2,…,Vn，hi为车载终端到第i个接入点所经历的跳数。记时刻s单位信息的收益为P(s)，参与者Vi的策略就是它提供的接入速率vi(s)，参与者Vi的成本主要考虑电源成本和网络成本，与其提供的接入速率为二次函数关系，记为vi 2bi+vici。记初始时刻单位信息的收益为P0，将Tsutsui和Mino定义的描述双寡头市场参与者策略关系推广到n个参与者，就得到n个接入点的竞争策略关系，也即时刻s单位信息的收益P(s)与参与者Vi的接入速率vi(s)之间的关系。
步骤54：针对每个竞争组，根据已建立的微分博弈模型，计算该竞争组的单位信息的收益和该竞争组中每个接入点需要为用户设备提供的接入速率。
步骤55：针对每个竞争组，计算出该竞争组中每个接入点当前能够提供的接入速率。
步骤56：针对每个竞争组，判断该竞争组中每个接入点当前能够提供的接入速率是否都不小于该接入点需要为用户设备提供的接入速率；
若是，执行步骤57；
若否，执行步骤58；
步骤57：计算该竞争组的接入开销，并执行步骤59；
步骤58：放弃这个竞争组；
步骤59：根据计算得到的竞争组的接入开销、以及用户设备对接入网络的网络质量的需求，为该用户设备选择一个竞争组进行接入。
