Description

资源调度方法和MME、eNodeB、UE 技术领域
本发明涉及通信技术，尤其涉及一种资源调度方法和MME、eNodeB、UE。
背景技术
接近业务(ProSe，Proximity based Services)是由第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)提出的，ProSe的应用之一是可以实现距离较近的两终端之间采用直接或者间接方式相互发现。在两终端相互发现的过程中，需要两终端(UE)中的一个终端(announcing UE)从基站(eNodeB)获取ProSe广播资源，从而根据获取到的ProSe广播资源对ProSe业务标识进行广播，以使两终端中的另一个终端(monitoring UE)根据广播的ProSe业务标识发现广播终端。
现有技术中，如果UE需要进入无线资源控制连接态，从而向eNodeB请求获取为该UE分配的专有的ProSe广播资源，并利用该专有的ProSe广播资源广播ProSe业务标识，在此期间UE必须保持在无线资源控制连接状态，一旦UE从无线资源控制连接态切换到空闲状态，为UE分配的专有的ProSe广播资源即不再可用。显然，现有技术中UE必须保持在无线资源控制连接态才能使用专有的ProSe广播资源广播ProSe业务标识，导致UE的电量消耗增大。

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。
图1为本发明第一个实施例提供的一种资源调度方法的流程示意图，如图1所示，包括：
101、移动管理实体(Mobility Management Entity，MME)接收第一消息。
其中，第一消息，是当UE小区重选后所驻留的目的eNodeB不同于所述UE小区重选前所驻留的源eNodeB时，所述UE通过该目的eNodeB向MME所发送的；所述第一消息用于请求为所述UE分配ProSe广播资源。
102、MME指示目的eNodeB为UE分配第一消息所请求的ProSe广播资源。
可选的，MME在指示目的eNodeB为UE分配资源之前，MME生成ProSe资源码(ProSe resource code)，ProSe资源码包括随机生成的随机码和生成所述ProSe资源码时所述UE所驻留的目的eNodeB的eNodeB标识。向所述UE的目的eNodeB发送包含ProSe资源码的ProSe广播资源分配请求，以使目的eNodeB为UE分配ProSe广播资源之后，建立所述ProSe资源码与为UE分配的ProSe广播资源之间的对应关系。所述对应关系，用于后续所述目的eNodeB根据ProSe资源码，释放ProSe资源码对应的ProSe广播资源。
或者，可选的，MME向所述UE的目的eNodeB发送包含所述UE的标识的ProSe广播资源分配请求，以使所述目的eNodeB根据所述ProSe广播资源分配请求的指示，为所述UE分配ProSe广播资源之后，建立所述UE的标识与为所述UE分配的ProSe广播资源之间的对应关系；所述对应关系，用于后续所述目的eNodeB根据UE的标识，释放UE的标识对应的ProSe广播资源。
进一步，资源调度方法还可包括：所述MME指示所述UE的源eNodeB释放已向所述UE分配的ProSe广播资源。
可选的，MME在收到第一消息后，判断其上是否已经保存有该UE的ProSe业务信息，该业务信息包括ProSe资源码，且该ProSe业务信息指示了已经为该UE分配了广播资源。如果MME确定已经保存有该UE的ProSe资源码， 则根据ProSe资源码中的eNodeB标识，即源eNodeB标识，向该源eNodeB发送第二消息；所述第二消息用于指示源eNodeB释放为该UE之前已经分配的ProSe广播资源，第二消息中包含ProSe资源码，以使得源eNodeB根据ProSe资源码匹配到对应的ProSe广播资源；ProSe资源码中的第一码字是随机生成的，第二码字用于标识分配ProSe广播资源的源eNodeB。
需要说明的是，第一消息可以为服务请求消息和\或跟踪区更新(Tracking Area Update，TAU)消息。
或者，可选的，MME在收到第一消息后，判断其上是否保存了该UE的ProSe业务信息，ProSe业务信息用于指示UE上存在ProSe业务，并已经为该UE分配了ProSe广播资源。如果MME确定保存有该UE的ProSe业务信息，则向源eNodeB发送第二消息；所述第二消息用于指示源eNodeB释放其已经为该UE分配的广播资源，第二消息中包含UE的标识，以使得eNodeB根据UE的标识匹配到对应的ProSe广播资源。
本发明实施例中，通过处于空闲状态的UE进行小区重选后所驻留的目的eNodeB不同于UE小区重选前所驻留的源eNodeB时，UE向网络实体请求获取目的eNodeB为其分配的ProSe广播资源，另外，还可触发源eNodeB释放为其分配的ProSe广播资源，从而解决现了有技术中UE必须保持在无线资源控制连接态才能使用专有的ProSe广播资源广播ProSe业务标识，导致UE的电量消耗增大的技术问题。
图2为本发明第二个实施例提供的一种资源调度方法的流程示意图，本实施例中UE小区重选前后eNodeB发生改变，小区重选前UE驻留在eNodeB B，小区重选后UE驻留在eNodeB A，如图2所示，资源调度方法包括：
