Description

一种实现邻近直接发现的方法、基站和终端 技术领域
本发明实施例涉及设备到设备(D2D，Device-to-Device)技术，尤指一种实现邻近直接发现的方法、基站和终端。
背景技术
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日益增长，从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。另一方面，随着社交网络、近距离数据共享、本地广告等应用的普及，人们对了解附近感兴趣的人或事物并与之通信(如邻近服务)的需求也逐渐增加。传统以基站为中心的蜂窝网络对高数据速率以及邻近服务(ProSe，Proximity Services)的支持存在明显的局限性。在这种需求背景下，代表未来通信技术发展新方向的设备到设备(D2D，Device-to-Device)技术应运而生。而D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足了上述高数据速率业务和邻近服务的要求。
D2D业务(或称为ProSe业务)可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备，即D2D用户设备(D2D UE，D2D User Equipment)在有网络基础设施或无网络基础设施的情况下进行D2D业务。D2D业务通常包括：邻近直接发现(PROSE DIRECT DISCOVERY)技术和D2D通信技术；其中，邻近直接发现技术是指用于判断或确定两个或两个以上D2D UE之间相互邻近(例如在可进行D2D通讯范围之内)，或用于判断或确定第一用户设备邻近第二用户设备的技术。通常，D2D UE间可通过发送或接收发现信号或发现信息来发现对方，在有蜂窝网络覆盖下，网络可辅助D2D UE进行邻近直接发现。D2D通信技术是指D2D UE之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
邻近区域的终端利用D2D通讯能够给终端带来很多好处，比如更高的速率，更低的延迟以及更小的功耗，同时也极大地提高了运营商的无线资源利用效率，D2D的中继(Relay)模式有利于运营商提高无线覆盖；对于应用 来说，利用D2D通讯过程中的邻近信息可以开发出更加吸引人的新业务。公共安全(Public Safety)系统也可以利用D2D技术实现没有无线覆盖的情况下终端之间的通讯。
邻近直接发现技术又可分为两种不同的方式，一种方式是D2D直接发现(Direct Discovery)；另一种方式为演进的分组网络(EPC，Evolved Packet Core)方式，也就是通过核心网保存各终端的地理位置信息，根据保存的信息进一步提供邻近直接发现功能。
在实际部署中，存在多个载波重叠覆盖的区域，其中，部分载波用于覆盖而其他载频用于提高吞吐量，因此，大部分终端将选择用于覆盖的载频作为服务小区(serving cell)。在这种情况下，如果这些终端需要进行邻近直接发现过程，则根据现有技术，只能使用服务小区的资源池的信息来发送邻近直接发现消息，这样，势必加重了服务小区的D2D资源池的负荷，从而增加了网络侧载频间负荷不均匀问题的风险，并降低了D2D UE的性能。

本发明的较佳实施方式
为了便于本领域技术人员的理解，下面结合附图对本发明实施例作进一步的描述，并不能用来限制本发明的保护范围。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各种方式可以相互组合。
本发明技术方案包括：包括基站配置用于终端实现邻近直接发现的异频邻近直接发现的发送资源池信息，并发送给终端。
图1为本发明实施例实现邻近直接发现的方法的流程图，如图1所示，包括：
步骤100：基站配置异频邻近直接发现的发送资源池信息并发送给终端。
本步骤中，基站可以通过无线资源控制(RRC，Radio Resource Control)消息将配置的异频邻近直接发现的发送资源池信息发送给终端。其中，RRC消息可以是系统广播消息或RRC专用消息。
本步骤中的异频邻近直接发现的发送资源池信息可以是异频邻近直接发现的发送资源池的配置信息，或者是异频支持邻近直接发现的发送指示。其中，
发送资源池的配置信息包括但不限于：资源池所定义的时频资源、和/或异频间同步时间差、和/或异频所归属的频率信息，以及公共陆地移动网络(PLMN，Public Land Mobile Network)列表信息等。此时，发送资源池的类型包括终端自主资源选择(UE Autonomous Resource Selection)，或者调度资源配置(Scheduled Resource Allocation)。
异频支持邻近直接发现的发送指示包括：可以支持邻近直接发现的发送的异频所归属的频率信息，及PLMN列表信息。此时，异频支持邻近直接发现的发送资源池的类型为终端自主选择资源。
其中，终端为空闲态或连接态。
步骤101：终端使用基站配置的异频邻近直接发现的资源池实现邻近直接发现。
当异频邻近直接发现的发送资源池信息是异频邻近直接发现的发送资源池的配置信息时，
本步骤具体包括：终端根据配置信息，使用异频邻近直接发现的发送资源池发送邻近直接发现消息，以实现邻近直接发现。
当异频邻近直接发现的发送资源池信息是异频支持邻近直接发现的发送指示时，
本步骤之前还包括：终端根据获得的异频支持邻近直接发现的发送指示，通过收听异频系统广播消息获得邻近直接发现的发送资源池的配置信息。本步骤具体包括：根据终端收听到的配置信息，使用异频邻近直接发现的发送资源池发送邻近直接发现消息，以实现邻近直接发现。
当异频邻近直接发现的发送资源池信息是异频支持邻近直接发现的发送指示，但是基站没有明确区分是异频支持邻近直接发现的发送(即不区分是服务小区支持邻近直接发现的发送，还是异频小区支持邻近直接发现的发送)时，
本步骤之前还包括：进入连接态的终端向基站发送第一邻近直接发现请求；基站将异频邻近直接发现的发送资源池的配置信息发送给终端。比如，终端可以在RRC消息的随路用户信息(Side link UE Information)消息中携带邻近直接发现请求。本步骤具体包括：根据接收到配置信息，使用异频邻近直接发现的发送资源池发送邻近直接发现消息，以实现邻近直接发现。
通过本发明实施例提供的技术方案，实现了D2D终端利用非服务小区资源池发送邻近直接发现消息，这样，降低了服务小区的D2D资源池的负荷，从而减少了网络侧载频间负荷不均匀问题的风险，并提高了D2D UE的性能。
进一步地，在基站配置异频邻近直接发现的发送资源池的配置信息的同时，本发明实施例方法还包括：配置服务小区的发送资源池并发送给终端。具体实现属于本领域技术人员的公知技术，并不用于限定本发明实施例的保护范围，这里不再赘述。这样，当终端检查到异频资源池未授权和/或PLMN选择失败时，终端也可以使用基站配置的服务小区的发送资源池实现邻近直接发现，进一步保证了邻近直接发现的顺利实现。
基站可以同时将服务小区的发送资源池的配置信息携带在系统广播消息或RRC专用消息中发送给终端。此时，
在步骤101中还包括：终端可以随机或自主选择发送资源池。
进一步地，在基站配置异频邻近直接发现的发送资源池的配置信息和服务小区的发送资源池的配置信息的同时，还可以包括：基站还配置发送资源池的优先级信息并发送给终端。此时，
在步骤101中还包括：终端根据优先级信息选择发送资源池。
这里，发送资源池包括：异频邻近直接发现的发送资源池即异频资源池，以及服务小区的发送资源池。
其中，优先级信息用于表明指示终端优先选择的发送资源池的信息。优先级信息中可以包括异频资源池和服务小区的发送资源池的优先级，也可以包括异频资源池和服务小区的发送资源池内包含的资源块的优先级信息。
进一步地，基站还可以为不同的终端设计不同的优先级，例如终端按照归属的PLMN不同，或者是否支持多个射频设备，或者终端是公共安全终端或是非公共安全的终端等选择不同的发送资源池。比如基站希望公共安全的终端优先选择服务小区的发送资源池，或希望有两个或两个以上射频设备的终端优先选择异频的发送资源池，则可以在优先级信息中体现，终端读取优先级信息后，再根据终端的PLMN，射频设备，公共安全属性等信息，选择不同的发送资源池即可。
进一步地，
步骤100中的异频邻近直接发现的发送资源池信息是异频邻近直接发现的发送资源池的配置信息。在步骤100之前还包括：终端在连接态向基站发 送第二邻近直接发现请求；基站配置终端进行异频测量，比如基站根据载频间负荷情况，希望终端在某异频资源上发送邻近直接发现消息；终端向基站上报测量结果。当测量结果显示终端进入到基站希望的频率的覆盖范围内，执行步骤100。
其中，基站配置终端进行异频测量的触发条件为：终端进入到基站希望的频率的覆盖范围内。比如：基站为终端配置异频测量时或之前，基站为终端配置服务小区的发送资源池；再如：当异频测量触发上报后，基站为终端配置异频发现的发送资源池的配置信息；又如：终端检查该异频资源池授权和/或PLMN选择成功后，覆盖服务小区的发送资源池。
进一步地，
步骤100中的异频邻近直接发现的发送资源池信息是异频支持邻近直接发现的发送指示。步骤100还包括：基站配置异频选择指示并发送给终端；此时，
步骤100与步骤101之间还包括：终端根据异频选择指示，在异频支持邻近直接发现的发送指示中确定自身感兴趣的频率和对应的PLMN列表信息；终端在连接态，将确定出的感兴趣的频率和对应的PLMN列表信息携带在邻近直接发现请求中发送给基站；基站根据载频负荷情况和终端感兴趣的载频，为终端配置频率以及频率上的发送资源池的配置信息。或者，
在步骤100与步骤101之间还包括：终端根据异频选择指示，在异频支持邻近直接发现的发送指示中确定自身感兴趣的频率，并将确定出的感兴趣的频率和终端自身支持的PLMN的列表携带在邻近直接发现请求中发送给基站；基站根据载频负荷情况和终端感兴趣的载频，为终端配置频率以及频率上的发送资源池的配置信息。
为了本地基站获取到邻区基站的配置信息，本发明实施例方法之前还包括：
基站间交互异频邻近直接发现的发送资源池信息。
异频邻近直接发现的发送资源池信息可以是异频邻近直接发现的发送资源池的配置信息，或者是异频支持邻近直接发现的发送指示。
其中，异频邻近直接发现的发送资源池的配置信息包括但不限于：资源池所定义的时频资源、和/或异频间同步时间差、和/或异频所归属的频率信息，以及PLMN列表信息等。
异频支持邻近直接发现的发送指示包括：可以支持邻近直接发现的发送的异频所归属的载频信息，及PLMN列表信息。
其中，
异频邻近直接发现的发送资源池的配置信息可以通过网管配置或通过基站间接口配置，其中，基站间接口可以是如X2接口；或者更优地，可以使用类型二的基本流程(Class 2Elementary Procedures)交互异频邻近直接发现的发送资源池的配置信息。

下面结合具体实施例对本发明实施例提供的技术方案进行详细描述。
图4为本发明实现邻近直接发现的第一实施例的流程示意图，第一实施例为基站为空闲(idle)UE提供异频配置，终端直接使用的场景。如图4所示，具体包括以下步骤：
步骤400：基站将异频邻近直接发现的发送资源池的配置信息携带在系统广播消息发送给终端。
第一实施例中，假设异频临近直接发现的发送资源池的类型为终端自主选择资源。
通过网管配置或通过基站间接口如X2接口，基站如eNB获得其他载频上的发送资源池的配置信息，包括资源池所定义的时频资源、和/或异频间同步时间差、和/或异频所归属的频率信息，以及PLMN列表信息等。
步骤401：终端使用接收到的异频邻近直接发现的发送资源池发送邻近直接发现消息。
终端处于空闲态时，如果接收到系统广播消息中的异频邻近直接发现的发送资源池的配置信息，此时的类型为终端自主选择资源类型，因此，终端可以在不改变服务小区的情况下使用接收到的载频上的发送资源池来发送邻近直接发现消息。
图5为本发明实现邻近直接发现的第二实施例的流程示意图，第二实施例为基站为idle UE提供异频支持邻近直接发现的发送指示，终端在idle态读取异频SIB后获取发送资源池的配置信息的场景，具体实现包括以下步骤：
步骤500：基站将异频支持邻近直接发现的发送指示携带在系统广播消息中发送给终端。
第二实施例中，假设异频临近直接发现的发送资源池的类型为终端自主选择资源。
通过网管配置或通过基站间接口，基站如eNB获得其他载频上可以支持邻近直接发现的发送信息，包括可以支持邻近直接发现的发送的异频所归属的频率信息，及PLMN列表信息。
步骤501：终端根据接收到的异频支持邻近直接发现的发送指示，通过收听异频系统广播消息获得邻近直接发现的发送资源池的配置信息。
本步骤中，终端可以在服务小区空闲态时，根据接收到的异频支持邻近直接发现的发送指示，主动接收异频系统广播消息，获得异频邻近直接发现的发送资源池的配置信息。
步骤502：终端使用获得的异频邻近直接发现的发送资源池发送邻近直接发现消息。
终端处于空闲态时，如果接收到所述系统广播消息中异频邻近直接发现的发送资源池的配置信息，此时的类型为终端自主选择资源类型，因此，终端可以在不改变服务小区的情况下使用获得的载频上的发送资源池发送邻近直接发现消息。
图6为本发明实现邻近直接发现的第三实施例和第四实施例的流程示意图，第三实施例为引导idle UE进入连接态，基站在专用信令中直接配置资源池的配置信息的场景，如图6所示，具体实现包括以下步骤：
步骤600：基站将异频支持邻近直接发现的发送指示携带在系统广播消息中发送给终端。
本实施例中，假设基站广播中并不区分是服务小区还是异频小区支持邻近直接发现的发送。比如，基站如eNB可以在系统广播消息19(SIB19)中指示其支持邻近直接发现，但不提供资源池的配置信息。
步骤601：终端进入连接态，向基站发送邻近直接发现请求。
当终端在系统广播消息中接收到支持邻近直接发现的发送指示后，如果终端需要发送邻近直接发现请求(如终端高层的软件有需要传递邻近发现请求时就会触发)，则终端会主动进入连接态。
终端可以在RRC消息的Side link UE Information消息中携带邻近直接发现请求。
步骤602：基站接收到邻近直接发现请求，将异频邻近直接发现的发送资源池的配置信息携带在配置消息中发送给终端。
本步骤中，基站可以根据载频间负荷情况，将同频和/或异频邻近直接发送资源池的配置信息发送给终端；
进一步地，基站也可以根据自身的安排优先选择合适的发送资源池的配置信息发送给终端，比如负荷较重的发送资源池放在列表前端，负荷较轻的发送资源池排在列表后端，这样，以便于终端根据列表的顺序选择发送资源池。
本实施例中，发送资源池的类型包括终端自主资源选择，或调度资源配置。
本步骤中的配置消息可以是RRC连接重配置(RRC Connection Reconfiguration)消息，比如新增字段用于指示异频邻近直接发现的发送资源池。于此同时，本实施例中还可以包括：服务小区的发现的发送资源池也可以同时携带在配置消息中发送给终端。
步骤603：终端使用获得的邻近直接发现的发送资源池发送邻近直接发现请求。
本步骤中，终端处于连接态时，还包括：检查基站配置的邻近直接发现资源池，检查授权和/或PLMN是否允许使用。如果基站为终端分配的高优先级的发送资源池不允许使用，终端继续检查次优先的资源池。选定成功后，终端可以在不改变服务小区的情况下使用选定的载频上的发送资源池发送邻近直接发现消息。
仍然参见图6，第四实施例为引导idle UE进入连接态，基站引导终端去读异频SIB的场景，与第三实施例不同的是：
在步骤602，本实施例中是基站根据载频间负荷情况，判断需要在异频上发送，将异频支持邻近直接发现的发送指示配置给终端；
通过网管配置或通过基站间接口，基站如eNB获得其他载频上可以支持邻近直接发现的发送信息，包括可以支持邻近直接发现的发送的异频所归属的频率信息和PLMN列表信息。
进一步地，基站还可以同时配置本载频，即服务小区发现的发送资源池。这样，当终端因PLMN选择失败或其他原因无法使用异频资源池时，可以使用本服务小区的资源池进行邻近直接发现消息的传递。
与第三实施例不同的是，此时，异频资源池的类型只能是自主资源选。
但是，服务小区发现的发送资源池的类型可以包括终端自主资源选择，或调度资源配置。
在步骤603中，本实施例具体实现是：终端处于连接态时，检查异频支持邻近直接发现的发送指示中的授权和/或PLMN是否允许使用，如果不允许使用，那么，基站检查自身是否还配置有服务小区的资源池；如果通过了授权和/或PLMN检查，终端在连接态时读取异频上的系统广播资源信息中的发送资源池的配置信息；
然后，终端可以在不改变服务小区的情况下使用获得的载频上的发送资源池发送邻近直接发现消息。
图7为本发明实现邻近直接发现的第五实施例的流程示意图，第五实施例中是在优化情况下，比如CA的某些场景下，基站要求终端进行异频测量，只有进入异频范围内才启动发送的场景，如图7所示，具体包括：
步骤700：终端在连接态向基站发送邻近直接发现请求。
终端终端可以在RRC消息的Side link UE Information消息中携带邻近直接发现请求。
步骤701：基站配置终端进行异频测量。
基站可以根据载频间负荷情况，希望终端在某异频资源上发送发现消息；基站为终端配置该频率的异频测量，触发条件为：终端是否进入到基站希望的频率的覆盖范围内。
较佳地，基站为终端配置服务小区的发现资源时，可以直接使用所述资源，也就是说，基站在配置终端进行测量的同时，也有可能会配置服务小区的发现的发送资源，因此，终端一旦收到这个配置后，在启动测量的同时，也可以同时使用基站配置的服务小区的发现的发送资源；
步骤702：终端上报测量结果，基站通过配置消息配置发送资源池配置。
当终端进入到基站希望的某频率的覆盖范围内时触发测量上报，基站收到测量报告后，基站再将异频邻近直接发现的发送资源池的配置信息发送给终端。
本实施例中，资源池的类型包括终端自主资源选择，或调度资源配置。
其中，上报测量结果的消息可以使用RRC测量上报消息。
其中，配置消息可以是RRC Connection Reconfiguration消息，比如新增字段用于指示异频邻近直接发现的发送资源池。于此同时，本实施例中还可以包括：服务小区的发现的发送资源池也可以同时携带在配置消息中发送给终端。配置消息也可以是新增RRC消息。
步骤703：终端使用获得的邻近直接发现的发送资源池发送邻近直接发现消息。
本步骤中，终端处于连接态时，还包括：检查基站配置的邻近直接发现资源池，检查授权和/或PLMN是否允许使用。比如步骤702中基站为终端分配的资源池不允许使用，那么，终端继续使用步骤701中配置的服务小区的资源池；如果步骤702中的资源池可以使用，那么终端删除步骤701中配置的资源池信息而改用步骤702中配置的资源池。
选定成功后，终端可以在不改变服务小区的情况下使用选定的载频上的发送资源池发送邻近直接发现消息。
图8为本发明实现邻近直接发现的第六实施例的流程示意图，第六实施例中为通过广播一个异频选择指示，终端可以向基站上报感兴趣的频率的场景，如图8所示，具体实现包括以下步骤：
步骤800：基站将异频支持邻近直接发现的发送指示和异频选择指示携带在系统广播消息中发送给终端。
其中，异频支持邻近直接发现的发送指示包括可以支持临近直接发现的发送的异频所归属的频率信息和PLMN列表信息；
异频选择指示使得终端不用直接去读异频的系统广播消息，而是可以根据异频支持邻近直接发现的发送指示中的频率和PLMN信息，选择自身感兴趣的PLMN下的频率。
步骤801：终端在连接态向基站发送邻近直接发现请求。
本步骤包括：终端根据异频选择指示，在异频支持邻近直接发现的发送指示中确定出自身感兴趣的频率和对应的PLMN列表信息。并将确定出的感 兴趣的频率和对应的PLMN列表信息携带在邻近直接发现请求中发送给基站。这里，邻近直接发现请求可以携带在RRC消息的Side link UE Information消息中。
步骤802：基站通过配置消息为终端配置发送资源池的配置信息。
本步骤包括：基站根据载频负荷情况和终端上报的感兴趣的载频，为终端配置频率以及该频率上的发送资源池。其中，发送资源池的类型包括终端自主资源选择，或调度资源配置。
其中，配置消息可以是RRC Connection Reconfiguration消息，比如新增字段用于指示异频邻近直接发现的发送资源池。于此同时，本实施例中还可以包括：服务小区的发现的发送资源池也可以同时携带在配置消息中发送给终端。配置消息也可以是新增RRC消息。
进一步地，本步骤还包括：基站同时为终端配置服务小区的资源池。
步骤803：终端使用获得的邻近直接发现的发送资源池发送邻近直接发现消息。
本步骤中，终端处于连接态时，还包括：检查基站配置的邻近直接发现资源池，检查授权和/或PLMN是否允许使用。比如步骤802中基站为终端分配的异频资源池不允许使用，那么，终端继续使用步骤801中配置的服务小区的资源池；如果步骤802中的资源池可以使用，那么终端使用异频资源池。
选定成功后，终端可以在不改变服务小区的情况下使用选定的载频上的发送资源池发送邻近直接发现消息。
图9为本发明实现邻近直接发现的第七实施例的流程示意图，第七实施例中为通过广播一个异频选择指示，终端可以向基站上报终端支持的PLMN的列表的场景，如图9所示，具体实现包括以下步骤：
步骤900：基站将异频支持邻近直接发现的发送指示和异频选择指示携带在系统广播消息中发送给终端。
步骤901：终端在连接态向基站发送邻近直接发现请求的同时提供终端支持的PLMN的列表。
本步骤包括：终端在流程之前已经获取到终端支持的PLMN的列表，终 端将该信息携带在邻近直接发现请求中发送给基站。这里，邻近直接发现请求可以携带在RRC消息的Side link UE Information消息中。
步骤902：基站通过配置消息为终端配置发送资源池的配置信息。
本步骤包括：基站根据载频负荷情况和终端上报的终端支持的PLMN的列表，为终端配置频率以及该频率上的发送资源池。其中，发送资源池的类型包括终端自主资源选择，或调度资源配置。
其中，配置消息可以是RRC Connection Reconfiguration消息，比如新增字段用于指示异频邻近直接发现的发送资源池。于此同时，本实施例中还可以包括：服务小区的发现的发送资源池也可以同时携带在配置消息中发送给终端。配置消息也可以是新增RRC消息。
进一步地，本步骤还包括：基站同时为终端配置服务小区的资源池。
步骤903：终端使用获得的邻近直接发现的发送资源池发送邻近直接发现消息。
本步骤中，终端处于连接态时，还包括：检查基站配置的邻近直接发现资源池，检查授权和/或PLMN是否允许使用。比如步骤902中基站为终端分配的异频资源池不允许使用，那么，终端继续使用步骤901中配置的服务小区的资源池；如果步骤902中的资源池可以使用，那么终端使用异频资源池。
选定成功后，终端可以在不改变服务小区的情况下使用选定的载频上的发送资源池发送邻近直接发现消息。
在图4所示的第一实施例的基础上，本发明实施例还提供第八实施例，第八实施例为基站为空闲(idle)UE提供异频配置和服务小区资源池配置，终端直接使用的场景，结合图4所示，具体包括：
在步骤400中，基站会将异频邻近直接发现的发送资源池的配置信息和服务小区资源池的配置信息携带在系统广播消息发送给终端；而且基站会同时配置发送资源池的优先级信息(这里，发送资源池包括：异频邻近直接发现的发送资源池即异频资源池，以及服务小区的发送资源池即服务小区资源池)。
第八实施例中，假设异频临近直接发现的发送资源池的类型为终端自主 选择资源。
通过网管配置或通过基站间接口如X2接口，基站如eNB获得其他载频上的发送资源池的配置信息，包括资源池所定义的时频资源、和/或异频间同步时间差、和/或异频所归属的频率信息，以及PLMN列表信息等。
其中的优先级信息用于表明指示终端优先选择发送资源池的信息。优先级信息中可以包括异频资源池和服务小区资源池的优先级，也可以包括异频资源池和服务小区资源池内包含的资源块的优先级信息。
进一步地，基站还可以为不同的终端设计不同的优先级，例如终端按照归属的PLMN不同，或者是否支持多个射频设备，或者终端是公共安全终端或是非公共安全的终端等选择不同的资源池。比如基站希望公共安全的终端优先选择本小区资源池，或希望有两个或两个以上射频设备的终端优先选择异频资源池，则可以在优先级信息中体现，终端读取优先级信息后，再根据终端的PLMN，射频设备，公共安全属性等信息，选择不同的发送资源池。
在步骤401中，终端会根据优先级信息选择发送资源池，并使用发送资源池发送邻近直接发现消息。
终端处于空闲态时，如果同时可以接收到系统广播消息中的异频邻近直接发现的发送资源池的配置信息和服务小区的发送资源池的配置信息，以及资源池的优先级信息，终端可以根据基站配置的优先级信息优先选择适合自身的发送资源池。
终端读取优先级信息后，也可以进一步根据终端的PLMN，射频设备，公共安全属性等信息，选择不同的发送资源池。
此时的类型为终端自主选择资源类型，因此，终端可以在不改变服务小区的情况下使用接收到的载频上的发送资源池来发送邻近直接发现消息。
在图4所示的第一实施例的基础上，本发明实施例还提供第九实施例，第九实施例为基站为空闲(idle)UE提供异频配置和服务小区资源池配置，终端随机使用资源池的场景，结合图4所示，具体包括：
在步骤400中，基站会将异频邻近直接发现的发送资源池的配置信息和服务小区资源池的配置信息携带在系统广播消息发送给终端。本实施例与第 八实施例的区别是：基站没有配置发送资源池的优先级信息。
第九实施例中，假设异频临近直接发现的发送资源池的类型为终端自主选择资源。
通过网管配置或通过基站间接口如X2接口，基站如eNB获得其他载频上的发送资源池的配置信息，包括资源池所定义的时频资源、和/或异频间同步时间差、和/或异频所归属的频率信息，以及PLMN列表信息等。
在步骤401中，终端会随机或自主选择发送资源池，并使用发送资源池发送邻近直接发现消息。
终端处于空闲态时，如果同时可以接收到系统广播消息中的异频邻近直接发现的发送资源池的配置信息和本小区的资源池的配置信息，但是没有接收到指示资源池优先级的优先级信息，终端可以随机选择资源池或自主选择发送资源池。其中，
自主选择资源池可以参考终端归属的PLMN信息，射频设备，公共安全属性，和历史选择等信息进行选择。比如：终端有多个射频设备，则可以自主优先使用异频资源池；再如：终端有公共安全的属性，则可以自主选择服务小区的发送资源池。
此时的类型为终端自主选择资源类型，因此，终端可以在不改变服务小区的情况下使用接收到的载频上的发送资源池来发送邻近直接发现消息。
在图6所示的实施例的基础上，本发明实施例还提供第十实施例，第十实施例为基站在专用信令中同时配置异频资源池的配置信息和服务小区资源池的配置信息的场景，结合图6所示，本实施例与第三实施例不同之处在于：
在步骤602中，本实施例中是基站可以同时配置异频资源池和服务小区资源池。基站还可以同时配置发送资源池的优先级信息。
其中的优先级信息用于表明指示终端优先选择发送资源池的信息。优先级信息中可以包括异频资源池和服务小区资源池的优先级，也可以包括异频资源池和服务小区资源池内包含的资源块的优先级信息。
进一步地，基站还可以为不同的终端设计不同的优先级，例如终端按照归属的的PLMN不同，或者是否支持多个射频设备，或者终端是公共安全终 端或是非公共安全的终端等选择不同的发送资源池。比如基站希望公共安全的终端优先选择本小区资源池，或希望有两个或两个以上射频设备的终端优先选择异频资源池，则可以在优先级信息中体现，终端读取优先级信息后，再根据终端的PLMN，射频设备，公共安全属性等信息，选择不同的发送资源池。
相应地，在步骤603中，本实施例中的终端可以随机或自主选择发送资源池，或根据基站配置的优先级信息选择发送资源池。
终端处于连接态时，如果基站通过专用RRC消息配置有异频邻近直接发现的发送资源池的配置信息和本小区的资源池配置信息，但是没有配置资源池优先级信息，终端可以随机选择资源池或自主选择发送资源池。如果基站配置有优先级信息，终端可以根据基站配置的优先级信息选择发送资源池。
其中，自主选择资源池可以参考终端归属的PLMN信息，射频设备，公共安全属性，和历史选择等信息进行选择。比如：终端有多个射频设备，则可以自主优先使用异频资源池；再如：终端有公共安全的属性，则可以自主选择本小区资源池。
此时的类型为终端自主选择资源类型，因此，终端可以在不改变服务小区的情况下使用获得的载频上的发送资源池发送邻近直接发现消息。
以上所述，仅为本发明的较佳实例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
