Description

一种分配资源和随机接入的方法及设备
本申请要求在2016年8月5日提交中国专利局、申请号为201610641040.3、发明名称为“一种分配资源和随机接入的方法及设备”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
本发明涉及无线通信技术领域，特别涉及一种分配资源和随机接入的方法及设备。
背景技术
在LTE(Long Term Evolution，长期演进)系统中随机接入的原因主要有如下几种：
1、从RRC(Radio Resource Control，无线资源控制)_IDLE(空闲)状态接入(也称为初始接入(initial access))；
2、无线链路失败发起RRC连接重建(也是初始接入的一种)；
3、切换过程需要随机接入；
4、UE(User Equipment，用户设备)处于RRC_CONNECTED(连接)时有下行数据到达；
5、UE处于RRC_CONNECTED时有上行数据到达。
对于有下行数据到达和切换两种情况，如果有专用preamble(前导)，则可以使用非竞争随机接入，非竞争随机接入的过程如下图1所示，主要分为三步：
Msg0：基站向UE分配用于非竞争随机接入的专用ra-PreambleIndex(Random Access Preamble Index，随机接入前导码序号)以及随机接入使用的RACH(Random Access Channel，随机接入信道)资源ra-RACH-MaskIndex(RACH Mask Index，RACH Mask编号)：对于下行数据到达引起的非竞争随 机接入使用PDCCH(Physical Downlink Control Channel，物理下行控制信道)携带这些信息，对于切换引起的非竞争随机接入通过handover command(切换命令)携带这些信息。
Msg1：UE根据Msg0指示的ra-PreambleIndex和ra-RACH-MaskIndex，在指定的PRACH(Physical Random Access Channel，物理随机接入信道)资源上向基站发送指定的专用preamble。基站接收到Msg1后根据Msg1计算上行定时提前量TA(Timing Advance，时间提前量)。
Msg2：基站向UE发送随机接入响应，随机接入响应中包含定时提前量信息，通知UE后续上行传输的定时提前量。
对于其它所有随机接入原因引起的随机接入均可以使用竞争随机接入，竞争随机接入的过程如下图2所示，主要分为四步：
Msg1：UE选择随机接入preamble和RACH资源并利用该RACH资源向基站发送所选的随机接入preamble；
Msg2：基站接收到preamble，计算定时提前量TA，并向UE发送随机接入响应，随机接入响应中至少包含该定时提前量信息和针对Msg3的UL grant(上行链路调度)；
Msg3：UE在Msg2指定的UL grant上发送上行传输，不同随机接入原因Msg3上行传输的内容不同，比如对于初始接入，Msg3传输的是RRC连接建立请求；
Msg4：竞争解决消息，UE根据Msg4可以判断随机接入是否成功。
根据当前5G的接入网侧的需求，覆盖范围需要达到100公里的要求，同时最大驻留用户数密度要求可以支持到每平方公里1000000个用户的要求。
5G中由于超大小区超密用户数的引入，为维持一个合理的随机接入碰撞概率，考虑到超大用户数的因素，系统实际配置的RACH资源可能会很多，这就需要对RACH资源进行配置，而目前如果要变更RACH资源，需要通过系统信息变更的过程来完成，变化速度比较慢。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部份实施例，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做出创造性劳动前提下所获得的其它所有实施例，都属于本发明保护的范围。
如图3所示，本发明实施例随机接入的系统包括：网络侧设备10和终端20。
网络侧设备10，用于判断是否需要调整RACH资源；在确定需要调整RACH资源后，通过L1信令和/或L2信令调整RACH资源。
终端20，用于确定网络侧设备通过L1信令和/或L2信令调整的RACH资源；通过调整后的RACH资源进行随机接入。
在本发明实施例中，网络侧设备在确定需要调整RACH资源后，通过L1信令和/或L2信令调整RACH资源。由于通过L1信令和/或L2信令调整RACH资源不需要执行系统信息变更的过程，因而可以提高配置RACH资源的速度；进一步的，也因此能保证随机接入资源的使用率，提高系统性能。
在本发明实施例中，调整RACH资源包括增加RACH资源、减少RACH资源以及变更RACH资源中的一种。
当然，也可以在增加RACH资源基础上变更RACH资源，或在减少RACH资源基础上变更RACH资源。
其中，网络侧设备判断是否需要调整RACH资源的方式有很多，至少包括以下列举的几种：
方式一、所述网络侧设备根据预设时间段内发生RACH碰撞的次数，判断是否需要调整RACH资源。
比如可以设定第一阈值和第二阈值，其中所述第一阈值大于第二阈值；
若预设时间段内发生RACH碰撞的次数大于第一阈值，则所述网络侧设备增加所述网络侧设备管理的小区的RACH资源；
若预设时间段内发生RACH碰撞的次数小于第二阈值，则所述网络侧设备减小所述网络侧设备管理的小区的RACH资源。
在实施中，时间段可以根据需要进行设置，比如可以设置一天、半天等。第一阈值和第二阈值可以根据经验、仿真等方式确定。
这里发生RACH碰撞的次数是指网络侧设备管理的小区内部发生RACH碰撞的次数。
方式二、所述网络侧设备根据由预知信息确定的不同时间段小区内的用户数量，判断是否需要调整RACH资源。
比如可以设定第三阈值和第四阈值，其中所述第三阈值大于第四阈值；
若当前所处的时间段小区内的用户数量大于第三阈值，则所述网络侧设备增加所述网络侧设备管理的小区的RACH资源；
若当前所处的时间段小区内的用户数量小于第四阈值，则所述网络侧设备减小所述网络侧设备管理的小区的RACH资源。
由于不同时间段用户数量可能不同，比如同一个区域早上、中午以及晚上用户数量就可能存在比较大的差异，所以设置多个不同的时间段可以更灵活对RACH资源进行调整。
在实施中，时间段可以根据需要进行设置，比如可以一天作为一个时间段、半天作为一个时间段等。第三阈值和第四阈值可以根据经验、仿真等方式确定。
这里小区内的用户数量是指网络侧设备管理的小区内的用户数量。
预知信息为可以预测之后一时间段内的用户数量的信息，比如在电影院覆盖中，根据电影排片的时间信息，来判断观影人数多的时间段。还比如针对场馆、展览馆等也可以根据比赛和展览的安排信息判断用户数量。
方式三、所述网络侧设备根据设定时间段内RACH资源使用情况，判断是否需要调整RACH资源。
比如可以设定第五阈值和第六阈值，其中所述第五阈值大于第六阈值；
若预设时间段内相邻小区发生RACH碰撞的次数大于第五阈值，且预设时间段内所述网络侧设备管理的小区发生RACH碰撞的次数小于第六阈值，则所述网络侧设备减少所述网络侧设备管理的小区的RACH资源；
若预设时间段内相邻小区发生RACH碰撞的次数小于第六阈值，且预设时间段内所述网络侧设备管理的小区发生RACH碰撞的次数大于第五阈值，则所述网络侧设备增加所述网络侧设备管理的小区的RACH资源；其中所述第五阈值大于第六阈值。
在实施中，时间段可以根据需要进行设置，比如可以一天作为一个时间段、半天作为一个时间段等。第五阈值和第六阈值可以根据经验、仿真等方式确定。
还比如若检测到相邻小区发生RACH资源碰撞，则所述网络侧设备确定需要调整RACH资源。
这里根据邻区RACH资源调整本区是为了避免收到邻小区UE发送的随机接入信号。比如如果邻区使用了某个特定资源，那么避免本区收到邻区小区的上行接入信号，所以需要尽可能规避本区和邻区RACH资源的重叠。如果邻区调整邻区的RACH资源，则本区也要调整邻区的RACH资源。
基于此如果邻区的RACH资源碰撞，则邻区调整邻区的RACH资源后， 为了避免本区和邻区的RACH资源碰撞，也需要调整本小区的RACH资源，以避免与邻区的RACH资源发生碰撞。
还比如若所述网络侧设备管理的小区的RACH负荷大于第七阈值，则所述网络侧设备增加所述网络侧设备管理的小区的RACH资源，若所述网络侧设备管理的小区的RACH负荷小于第八阈值，则所述网络侧设备减少所述网络侧设备管理的小区的RACH资源。
其中，第七阈值和第八阈值可以根据经验、仿真等方式确定。第七阈值大于第八阈值。
本发明实施例网络侧设备可以先通过系统信息为终端配置RACH资源，之后在确定需要调整RACH资源后，通过L1信令和/或L2信令调整RACH资源。
可选的，所述网络侧设备调整RACH资源为所述网络侧设备管理的小区的部分或全部RACH资源。具体包括下面三种情况。
情况1、调整的RACH资源是系统信息配置的部分或全部RACH资源。
也就是说，系统信息配置RACH资源是全集，后续调整的RACH资源不能超过系统信息配置的RACH资源。
比如：系统信息配置RACH资源包括A、B、C和D，则后续只能在A、B、C和D中进行调整。
情况2、调整的RACH资源包括系统信息配置的RACH资源。
也就是说，系统信息配置RACH资源是最小集合，后续调整的RACH资源不能小于系统信息配置RACH资源。
比如系统信息配置RACH资源包括A、B、C和D，则后续调整时必须包括A、B、C和D。
情况3、调整的RACH资源包括所述网络侧设备通过系统信息配置的RACH资源中的部分RACH资源或不包括系统信息配置的RACH资源。
也就是说，系统信息配置RACH资源和后续调整的RACH资源之间没有任何关系，后续调整的RACH资源可以完全修改系统信息配置RACH资源。
在实施中，所述网络侧设备可以发送N次用于调整RACH资源的L1信令和/或L2信令，其中N为正整数，比如N可以是1，具体N值可以根据需要、仿真、经验等设定。
所述网络侧设备也可以周期发送用于调整RACH资源的L1信令和/或L2信令。
可选的，所述网络侧设备调整的RACH资源用于M次随机接入过程，其中M为正整数，比如M可以是1，具体N值可以根据需要、仿真、经验等设定。
如果M是1，则终端在用调整后的RACH资源进行了1次随机接入过程后就可以丢弃调整后的RACH资源，并恢复通过系统信息配置的RACH资源。
除了上面提到的调整的RACH资源用于M次随机接入过程，终端也可以将所述网络侧设备调整的RACH资源替换系统信息配置的RACH资源，则后续随机接入过程都采用调整的RACH资源。
可选的，本发明实施例的L1(层1)信令为物理层控制信道携带的信息；
本发明实施例的所述L2(层2)信令为L2控制单元携带的信息。
可选的，所述网络侧设备通过L1信令和/或L2信令调整RACH资源时，只将调整后的RACH资源的配置信息置于L1信令和/或L2信令中发送。
具体的，所述网络侧设备将用于表示调整后的RACH资源的信息，通过L1信令和/或L2信令发送，即full config配置方式，终端根据用于表示调整后的RACH资源的信息就可以确定调整后的RACH资源，比如调整后的RACH资源包括A、B和C，则用于表示调整后的RACH资源的信息包括A、B和C的信息；
相应的，终端根据信息确定调整的RACH资源。或，
所述网络侧设备将用于表示调整后的RACH资源中与前次配置的RACH资源不同的RACH资源的信息，通过L1信令和/或L2信令发送，即delta config配置方式，终端根据用于表示调整后的RACH资源中与前次配置的RACH资源不同的RACH资源的信息，以及前次配置的RACH资源，就可以确定调整 后的RACH资源，比如调整后的RACH资源包括A、B和C，前次配置的RACH资源包括A和B，则用于表示调整后的RACH资源中与前次配置的RACH资源不同的RACH资源的信息包括C的信息；
相应的，终端根据信息和前次配置的RACH资源确定调整的RACH资源。
可选的，用于表示调整后的RACH资源的信息为RACH资源的参数(显示指示)或RACH资源的序号(index方式)；或，
用于表示调整后的RACH资源中与前次配置的RACH资源不同的RACH资源的信息为RACH资源的参数或RACH资源的序号。
对于终端，如果需要进行随机接入，且接收到用于RACH调整的L1信令和/或L2信令，则通过调整后的RACH资源进行随机接入；否则通过系统信息配置的RACH资源进行随机接入。
对于终端，如果需要进行随机接入，也可以通过系统信息配置的RACH资源进行随机接入，在后续由于各种原因，需要重新进行随机接入时，通过调整后的RACH资源进行随机接入。这种方式网络侧设备可以通过随机接入过程中的L2信令配置RACH资源，比如RAR(Random access response，随机接入响应)消息。
其中，本发明实施例的网络侧设备可以是基站(比如宏基站、家庭基站等)，也可以是RN(中继)设备，还可以是其它网络侧设备。

下面以实例对本发明的方案的具体实施方式进行说明。
实施例1、通过L1和/L2信令调整RACH资源，并且调整的RACH资源覆盖系统信息配置的RACH资源。
如图10所示，本发明实施例第一种动态配置的方法包括：
步骤1、网络侧设备发送SIB(System Information Block，系统信息块)。
其中，系统信息中包括用于配置RACH资源的Cfg-1。
Cfg-1可以是具体资源的参数配置，也可以是预配置RACH资源配置表中的某个特定配置的索引。
步骤2、终端存储根据Cfg-1确定的RACH资源配置。
步骤3、网络侧设备判断当前的RACH系统资源负荷过重(例如通过最近T时间段内RACH碰撞概率的统计超过预定义门限，或者当前已在某特定区域内接入的用户数或者处于非激活态的用户数超过预定义门限)，则通过L1和/或L2信令携带调整的RACH资源配置Cfg-2。
其中，Cfg-2可以是完整的RACH配置消息，也可以是基于广播中Cfg-1给出增加或减少的RACH配置，表达形式可以给出具体资源的配置信息，也可以给出预定义或预配置的RACH配置表中资源的索引；
L1信令可以通过特定的控制信道或数据信道来携带更新的RACH信令，和/或用特定的RNTI进行指示；
L2信令可以通过特定的MAC CE携带；
步骤4、用户侧检测到L1和/或L2信令获知RACH资源发生变化，并根据Cfg-2更新自己内部保存的RACH资源配置；
步骤5、当UE要发起随机接入过程，则直接根据当前存储的RACH Cfg-2发起接入过程。
实施例2、RACH资源调整仅用于一次随机接入过程。
如图11所示，本发明实施例第二种动态配置的方法包括：
步骤1、网络侧设备发送系统信息块。
其中，系统信息中包括用于配置RACH资源的Cfg-1。
Cfg-1可以是具体资源的参数配置，也可以是预配置RACH资源配置表中的某个特定配置的索引。
步骤2、终端存储根据Cfg-1确定的RACH资源配置。
步骤3、UE用根据Cfg-1确定的RACH资源配置发起随机接入过程。
步骤4、网络侧设备检测到当前RACH负载过重，通过L1和/或L2信令携带调整的RACH资源配置Cfg-2。
其中，L1和/或L2信令可以直接通过Msg2消息携带；也可以不通过Msg2消息携带，而是作为独立的信令。
步骤5、UE根据L1和/或L2信令更新本次RACH过程使用的RACH资源配置。
当随机接入过程失败，则用根据Cfg-2更新的RACH资源配置重新发送随机接入序列。
这里可以停止之前的RACH过程重新发起一个新的随机接入过程，也可以不中断当前的随机接入过程，直接应用更新的配置进行重传。
当随机接入失败后，终端丢弃根据Cfg-2更新的RACH资源配置，恢复根据Cfg-1确定的RACH资源配置。
