具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
在本公开的实施例中，MulteFire可以支持PLMN接入模式和NHN接入模式。在MulteFire的NHN网络中引入了PSP-ID以实现支持多种服务提供商，本公开实施例可以应用到如NHN网络的系统架构中。下面将示例性地描述PLMN接入模式的系统架构和NHN接入模式的系统架构。
其中，PLMN接入模式的系统架构可以如图1所示，MulteFire的用户终端(User Equipment，UE)与MulteFire的无线接入网(Radio Access Network，RAN)中的接入点(Access Point，AP)建立通信，其中，MulteFire简称MF，MulteFire的UE简称MF-UE，MulteFire的RAN中的AP简称MF-AP。另外，MulteFire的RAN还可以与演进的分组核心网(Evolved Packet Core network，EPC)中的移动管理模块(Mobility Management Entity，MME)以及服务网关(Serving Gateway，SGW)建立通信，另外，MulteFire的RAN还可以与第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)RAN建立通信，且3GPP RAN还可以与EPC建立通信。在EPC中，MME可以与归属签约用户服务器(Home Subscriber Server，HSS)建立通信，SGW可以与PDN网关(PDN Gateway，PGW)，PGW还可以与策略与计费规则功能单元(Policy & Charging Rules Function，PCRF)建立通信，以及PGW和PCRF还可以与运营商IP业务(Operator’s IP Services)实体建立通信。
其中，NHN接入模式的系统架构可以如图2所示，UE与MF-AP建立通信，MF-AP还可以与中立主机核心网络(Neutral Host Core Network)中的MME和网关(Gateway，GW)建立通信，其中，中立主机核心网络中的MME简称NH MME，中立主机核心网络中的网关(Gateway，GW)简称NH GW，且NH MME可以中立主机核心网络中的本地验证、授权和记账(Local Authentication、Authorization、Accounting，Local AAA)实体建立通信，且NH MME还可以与NH GW建立通信，以及还可以与远程AAA(Remote AAA)和3GPP AAA建立通信，另外，NH GW还可以与外部IP网络(External IP  network)建立通信。
在本公开实施例中，每个参与的服务提供商对应一个PSP-ID，其中，参与的服务提供商可以理解为参与MulteFireNHN模式网络的服务提供商，例如：包括但不限于互联网服务提供商、有限电视、移动网络运营商、企业及公共场所服务提供商等。
另外，本公开实施例可以应用于移动通信包括但不限于码分多址2000(Code Division Multiple Access 2000，CDMA2000)、宽带CDMA(Wideband CDMA，WCDMA)、时分的同步CDMA(Time Division-Synchronous CDMA，TD-SCDMA)、全球微波互联接入(Worldwide Interoperability for Microwave Access，WiMAX)、LTE/LTE-A、LAA、MulteFire以及后续可能出现的第五代、第六代、第N代移动通信技术。其中，应用的MulteFire可以包括NHN接入模式，以及还可以应用于MulteFire的同时支持NHN接入模式和PLMN接入模式的混合模式等，对此本公开实施例不作限定。
另外，本公开实施例中，UE可以指能够支持陆地移动通信系统的通信协议的终端侧产品、特制通信的调制解调器模块(Wireless Modem)，其可以被手机、平板电脑、数据卡等各种类型的终端形态集成从而完成通信功能。例如：UE可以是手机，或者其他能够发送或接收无线信号的设备，如个人数字助理(PDA)、无线调制解调器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(WLL)站、能够将移动信号转换为WiFi信号的CPE(Customer Premise Equipment，客户终端设备)或移动智能热点、智能家电、或其他不通过人的操作就能自发与移动通信网络通信的设备等。
在本公开实施例中，接入设备可以是基站或者AP，当然可以理解的是，上述基站的形式不限，可以是宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(ENB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HNEB)、中继站、RRU(Remote Radio Unit，远端射频模块)、RRH(Remote Radio Head，射频拉远头)等。
请参阅图3，图3是本公开实施例提供的一种服务提供商标识指示方法的流程示意图，如图3所示，包括以下步骤：
301、UE通过PRACH向接入设备发送接入请求消息，其中，所述接入请 求消息至少用于指示所述UE需要传输的PSP-ID的数量。
本实施例中，上述接入请求消息可以是UE建立无线资源控制(Radio Resource Control，RRC)连接过程中的Msg1消息，例如：随机接入请求消息。
另外，上述UE需要传输的PSP-ID可以是UE需要向接入设备上报的完整格式的PSP-ID或压缩格式的PSP-ID，其中，这里PSP-ID可以是UE支持的PSP的标识。
302、UE接收所述接入设备发送的上行资源的资源信息，其中，所述上行资源为所述接入设备根据所述UE需要传输的PSP-ID的数量选择的，且用于传输所述UE需要传输的PSP-ID。
当上述接入设备接收到上述接入请求消息时，就可以通过该接入请求消息确定UE需要传输的PSP-ID的数量，从而根据该数量选择用于传输上述UE需要传输的PSP-ID的上行资源。其中，上述步骤302可以是接收上述接入设备发送的随机接入响应消息中的上行授权资源的资源信息。
由于上述上行资源是接入设备根据UE需要传输的PSP-ID的数量选择的，这样就可以选择适合上述PSP-ID的数量的上行资源，从而可以提高PSP-ID传输的可靠性和效率。具体的接入设备还可以根据PSP-ID的数量以及现有的功率和路损特性选择合适大小的上行资源，例如：选择合适大小的上行授权资源(UL grant)。
另外，本实施例中，对上述上行资源不作限定，例如，上述上行资源可以是RRC连接建立请求消息的传输资源，即Msg3消息的传输资源，这样可以实现在Msg3消息中传输PSP-ID。另外，上述上行资源还可以是传输其他消息的上行资源，例如：Msg7消息的传输资源，即可以实现在Msg7消息中传输PSP-ID。
本实施例中，UE通过PRACH向接入设备发送接入请求消息，其中，所述接入请求消息至少用于指示所述UE需要传输的参与的服务提供商标识PSP-ID的数量；UE接收所述接入设备发送的上行资源的资源信息，其中，所述上行资源为所述接入设备根据所述UE需要传输的PSP-ID的数量选择的，且用于传输所述UE需要传输的PSP-ID。从而可以实现UE使用该上行资源上报PSP-ID。
请参阅图4，图4是本公开实施例提供另一种服务提供商标识指示方法的流程示意图，如图4所示，包括以下步骤：
401、UE通过PRACH向接入设备发送接入请求消息，其中，所述接入请求消息至少用于指示所述UE需要传输的PSP-ID的数量。
可选的，上述接入请求消息可以包括：
解调参考信号(Demodulation Reference Signal，DMRS)序列，即可以通过DMRS序列指示PSP-ID的数量。其中，所述DMRS序列所属的DMRS序列分组与所述UE需要传输的PSP-ID的数量存在对应关系，且所述接入设备使用该对应关系确定所述需要传输的PSP-ID的数量，或者所述DMRS序列与所述UE需要传输的PSP-ID的数量存在对应关系，且所述接入设备使用该对应关系确定所述需要传输的PSP-ID的数量。
例如：UE可以根据预先获取的DMRS序列所属的DMRS序列分组与所述UE需要传输的PSP-ID的数量的对应关系，在上述接入请求消息中传输上述DMRS序列。例如：【0：n】表示无PSP-ID，即DMRS序列的序号为0至n内时就表示0个PSP-ID；【n+1：m】表示最大k个PSP-ID或者k个PSP-ID，即DMRS序列的序号为n+1至m内时就表示k个PSP-ID；【m+1：p】表示最大q个PSP-ID，或者q个PSP-ID，即DMRS序列的序号为m+1至p内时就表示q个PSP-ID。这样根据该对应关系就可以在上述接入请求消息中传输对应的DMRS序列，同理，接入设备根据该对应关系就可以确定PSP-ID的数量。其中，n为大于或等于0的整数，m为大于或等于n+1的整数，p为大于或等于m+1的整数；且k为大于0的整数，q为大于k的整数。
例如：UE可以根据预先获取的DMRS序列与所述UE需要传输的PSP-ID的数量的对应关系，在上述接入请求消息中传输上述DMRS序列，例如：该对应关系表示不同的DMRS序列对应不同的PSP-ID数量。这样根据该对应关系就可以在上述接入请求消息中传输对应的DMRS序列，同理，接入设备根据该对应关系就可以确定PSP-ID的数量。
另外，该实施方式中，以上述PRACH采用短物理上行链路控制信道(short Physical Uplink Control Channel，sPUCCH)为例进行举例说明，其中，物理上行链路控制信道的格式，即4个块交织的频分复用接入(Block Interleaved  FDMA，B-IFDMA)符号分别为PPDD，其中，P表示导频符号(Pilot)，D表示数据符号(Data)。当PRACH占用全部4个符号时，在一个interlace的每一个物理资源块(Physical Resource Block，PRB)内频域通过循环移位(cyclic shift，CS)正交，且时域通过正交覆盖码(Orthogonal Cover Code，OCC)正交。例如：如图5左边所示，在一个interlace内的每一个PRB内，PP内OCC正交，DD内OCC正交，其中DD可以传输指定的一个QPSK正交相移键控(Quadrature Phase Shift Keying，QPSK)符号或者一个DMRS序列，一个交织单元(interlace)内支持最大24个正交序列，支持与其他类型sPUCCH在相同interlace内复用，这样就可以在数据符号内传输DMRS序列。或者，如图5右边所示，PPDD内OCC正交时，传输相同的DMRS序列，一个interlace内支持最大48个正交序列，当PRACH仅占用前两个符号即PP时，支持最大24个正交序列，这样可以实现在导频符号内传输DMRS序列。
可选的，上述接入请求消息可以包括：指示所述UE需要传输的PSP-ID的数量的指示信息，其中，所述指示信息在所述PRACH中的数据符号中传输。
该实施方式中，可以实现通过数据符号传输上述指示信息，即接入设备可以通过数据符号承载的信息确定PSP-ID的数量。
可选的，该实施方式中，上述PRACH中的数据符号中的QPSK承载所述指示信息。即通过数据符号中的QPSK传输指示信息。例如：当PRACH包含数据符号(D)时，可以在每个D上对应的QPSK符号上承载相应的指示信息，具体可以将指示信息进行编码，并编码后的指示信息及循环冗余校验码(Cyclic Redundancy Code，CRC)一同映射到同一interlace内的一个或者多个数据符号中的QPSK符号上进行传输。另外，不同PRACH的D格式对应不同数目的数据符号，例如：PRACH的B-IFDMA符号PPDD仅通过CS循环移位在频域进行正交，如图6左边所示，则一个物理资源块(PhysicalResource Block，PRB)带宽内承载2个QPSK符号，假设20MHz系统带宽下，1个interlace包含10个PRB，传输40个比特，这样就可以使用40个比特承载上述指示信息和CRC。又或者，PRACH的B-IFDMA符号PP和DD分别进行OCC，如图6右边所示，则一个RB带宽内承载1个QPSK符号，假设20MHz系统带宽下，1个interlace包含10个PRB，这样就可以使用20个比特承载上述指示 信息和CRC。
需要说明的是，该实施方式可以与上述DMRS序列的实施方式结合实现，即上述接入请求消息可以包括上述DMRS序列和上述指示信息，当然，这两种实施方式可以分开实现，即上述接入请求消息包括上述DMRS序列或者上述指示信息。
可选的，上述UE通过PRACH向接入设备发送接入请求消息，可以包括：
UE从预先获取的交织单元(interlace)编号与PSP-ID数量的对应关系中，选择所述UE需要传输的PSP-ID的数量对应的interlace，并通过所述interlace对应的PRACH向接入设备发送接入请求消息，所述接入设备根据所述interlace与PSP-ID数量的对应关系确定所述interlace对应的所述UE需要传输的PSP-ID的数量。
该实施方式中，可以实现指定PRACH在不同interlace编号对应不同数目的PSP-ID上报。例如，对于20MHz的系统带宽，具备10个interlace，接入设备侧可以分配4个的PRACH对应不同的interlace编号，如interlace编号0，1，2，3，分别对应PSP-ID的数目0，1，2，3。这样UE可以根据不同的PSP-ID数量选择对应interlace编号，从而选择对应的PRACH向接入设备发送接入请求消息。例如：UE需要传输的PSP-ID的数量为3时，则可以选择编号为3的interlace对应的PRACH向接入设备发送接入请求消息。当接入设备在PRACH检测到的上述接入请求消息时，就可以确定该PRACH对应的interlace的编号，从而确定PSP-ID的数量。
这里需要说明的是，interlace编号与PSP-ID数量的对应关系可以是UE预先接收接入设备发送的，但该接入设备与步骤401中的接入设备可以是相同或者不同的接入设备，对此本实施例不作限定。
另外，本实施例中，DMRS序列、指示信息和interlace编号与PSP-ID数量的对应关系的三种实施方式可以结合在一起实现，也可以是interlace编号与PSP-ID数量的对应关系分别与DMRS序列或者指示信息的实施方式结合实现，这样可以使接入设备更加容易确定PSP-ID的数量。
可选的，上述DMRS序列和/或指示信息还可以指示PSP-ID的相关信息，例如：DMRS序列和/或指示信息还可以指示接入设备广播或者单播当前未被 广播的PSP-ID，这样可以实现通过DMRS序列和/或指示信息同时指示PSP-ID的数量，以及指示接入设备广播或者单播当前未被广播的PSP-ID；又或者DMRS序列和/或指示信息还可以指示已广播的PSP-ID的对应编号，这样可以实现通过DMRS序列和/或指示信息同时指示PSP-ID的数量，以及指示已广播的PSP-ID的对应编号。
该实施方式中通过DMRS序列和/或指示信息指示更多关于PSP-ID的信息，从而不需要额外增加其他步骤来实现对这些信息的指示，以节约网络传输资源、
402、UE接收所述接入设备发送的上行资源的资源信息，其中，所述上行资源为所述接入设备根据所述UE需要传输的PSP-ID的数量选择的，且用于传输所述UE需要传输的PSP-ID。
可选的，上述UE接收所述接入设备发送的上行资源的指示信息，可以包括：
所述UE接收所述接入设备发送的随机接入响应消息，所述随机接入响应消息中包括上行资源的指示信息。
该实施方式中，可以实现在发送接入请求消息的过程中向接入设备上报UE需要传输的PSP-ID的数量。
可选的，上述方法还可以包括如下步骤：
403、UE使用所述上行资源向上述接入设备发送的携带有PSP-ID的上行消息。
其中，这里的上行消息可以是RRC建立过程中的Msg3消息，也可以是其他场景中的上行消息，对此本实施例不作限定。另外，这里传输的PSD-ID即上述介绍的UE需要传输的PSP-ID。另外，这里需要传输的PSP-ID的可以一个或者多个，另外，在一些场景中上述PSP-ID的数量还可以是0个。
本实施例中，在图3所示的实施例的基础增加了多种可选的实施方式，且都可以实现UE对PSP-ID的上报。
