【具体实施方式】
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性的劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，图1是本申请提供的提高通信距离的方法一实施例的流程示意图，该方法应用于宽窄带融合系统，该方法包括：
步骤11：主叫终端向主叫中转终端发送业务请求。
宽窄带融合系统包括多个终端，主叫中转终端为具有中转功能的终端，其能够接收并转发业务请求，主叫终端为工作在DMO模式下的终端，其能够发送或者接收业务请求；具体地，主叫终端为发起业务请求的终端，主叫中转终端为与主叫终端位于同一网络的终端；主叫中转终端与被叫中转终端可为多模终端，即可工作在宽带模式下，也可工作在窄带模式下。
进一步地，宽窄带融合系统可包含多个独立网络，每个独立网络包含多个终端，每个独立网络的工作频率可不同，每个独立网络中的具有中转功能的终端可为一个，接收或者发起业务请求的终端的数量可为多个，例如，以如图2所示的宽窄带融合系统为例，其包括宽带基站21以及多个独立网络LA1-LAn，独立网络LA1包含终端MS1与终端MS2，独立网络LA2包含终端MS3与终端MS4，独立网络LAn包含终端MSn与终端MSn+1，每个独立网络都配置相同的窄带组与宽带组，即每个独立网络都在相同的窄带组与宽带组中，以主叫终端为独立网络LA1中的终端MS2为例，其要与宽窄带融合系统中的终端MS4进行通信，即被叫终端为终端MS4，主叫终端MS2先将业务请求发送到与其处于同一独立网络LA1下的主叫中转终端MS1中，然后通过主叫中转终端MS1将该业务请求转发出去，以便建立起与被叫终端MS4之间的业务连接，使得持有主叫终端MS2的用户与持有被叫终端MS4的用户能够进行通话。
可以理解地，主叫终端也可对该窄带组中的所有终端进行组呼，通过主叫中转终端、宽带基站以及被叫中转终端对业务请求进行转发，以与窄带组下的所有终端建立业务连接。
步骤12：主叫中转终端将业务请求发送至宽带基站，以使得宽带基站将业务请求转发至相应的被叫中转终端。
主叫中转终端将接收到的业务请求发送到宽带基站，然后宽带基站再将业务请求转发至相应的被叫中转终端，该被叫中转终端为与被叫终端位于同一独立网络的终端。具 体地，宽窄带融合系统中的主叫中转终端可对接收到的信号进行中转，主叫中转终端在接收到主叫终端发送的业务请求后，能够将该业务请求转发到宽带基站中，以使得主叫终端的业务请求能够通过宽带基站被转发到被叫中转终端中。
继续以图2中的宽窄带融合系统为例，主叫中转终端MS1将接收到的业务请求发送至宽带基站21，由于主叫终端MS2要与被叫终端MS4建立通信，宽带基站21在接收到该业务请求后将其转发到被叫中转终端MS3，以使得被叫中转终端MS3再在其对应的独立网络LA2中对该业务请求进行转发。
步骤13：被叫中转终端将业务请求转发至被叫终端，以建立主叫终端与被叫终端之间的业务连接。
被叫中转终端在接收到业务请求后，再将该业务请求转发到被叫终端，从而建立主叫终端与被叫终端之间的业务连接，如图2中的被叫中转终端MS3将接收到的业务请求转发到被叫终端MS4中，以建立主叫终端MS2与被叫终端MS4之间的业务连接。
本实施例提供了一种提高通信距离的方法，主叫终端先将业务请求发送给主叫中转终端，主叫中转终端在接收到业务请求后将其转发至宽带基站，以使得宽带基站将该业务请求转发至与被叫终端在同一独立网络下的被叫中转终端，被叫中转终端将接收到的业务请求转发至被叫终端，以建立主叫终端与被叫终端间的业务连接；发起呼叫的终端能够通过与其位于同一网络的终端中转业务请求，并通过宽带基站将业务请求转发到被叫终端中，通过设置中转终端能够增加主叫终端与被叫终端之间的通信距离，同时由于中转终端将业务请求转发到宽带基站，能够通过宽带系统将业务请求转发到其他工作频率不同的独立网络下的终端，从而实现跨频点的终端之间的通信。
请参阅图3，图3是本申请提供的提高通信距离的方法另一实施例的流程示意图，该方法应用于宽窄带融合系统，宽窄带融合系统包括多个终端，该方法包括：
步骤31：终端广播存在信息。
为了构建宽窄带融合系统中各个独立网络中的终端间的通信连接，每个独立网络下的其中一个终端广播存在信息，使得与该终端位于同一网络的其他终端能够接收存在信息，以建立该独立网络下的终端之间的通信连接。
可以理解地，宽窄带融合系统中的每个终端都配置相同的宽带组与宽带组，而每个独立网络的工作频率可不同，与广播存在信息的终端的工作频率相同的终端会接收到该终端广播的存在信息。
步骤32：接收到存在信息的终端建立与发送存在信息的终端之间的通信连接。
在接收到其中一个终端广播的存在信息后，接收到存在信息的其他终端根据存在信息建立与发送存在信息的终端之间的通信连接，具体地，存在信息可包括发送存在信息的终端的地址信息，其他终端可根据该地址信息与该终端连接，从而构建在独立网络下终端间的通信连接。
可以理解地，宽窄带融合系统中的独立网络可为多个，每个独立网络下的终端的数量也可为多个，与广播存在信息的终端工作频率相同的其他终端都可接收到该存在信息。例如，以如图2所示的宽窄带融合系统为例，该系统包括两个独立网络：独立网络LA1以及独立网络LA2，独立网络LA1中的终端MS2接收终端MS1广播的存在信息并与其建立联系，独立网络LA2中的终端MS4接收终端MS3广播的存在信息并与其建立联系。
步骤33：主叫终端将业务请求发送至主叫中转终端中的窄带模块。
主叫终端将业务请求发送至主叫中转终端中的窄带模块，以使得窄带模块将业务请求转发至主叫中转终端中的宽带模块；具体地，主叫中转终端包括互相连接的窄带模块与宽带模块，即多模终端，窄带模块的工作模式可以为中继模式，宽带模块的工作模式可以为宽带集群模式；宽窄带融合系统中的主叫终端为工作在DMO模式的终端，以进行业务请求的发送或者接收，进一步地，终端也可为窄带终端，即只工作在窄带系统的终端，其也可为窄带模块工作在DMO模式下的多模终端，即不具有中转功能，只进行业务请求的发送或者接收，在具体实施例中，主叫终端的类型可包括但不局限于窄带终端与多模终端；可以理解地，被叫终端或者每个独立网络下的不具有中转功能的终端的类型与主叫终端的类型设置相同，被叫中转终端或者每个独立网络下的具有中转功能的终端的类型与主叫中转终端的类型设置相同。
例如，以如图4所示的宽窄带融合系统为例，终端中的工作在中继模式的窄带模块用Repeater表示，工作在宽带集群模式的宽带模块用BB表示，该宽窄带融合系统包含四个独立网络，分别为LA1-LA4，主叫终端为终端MS2，被叫终端为终端MS6，主叫终端MS2将业务请求发送至主叫中转终端MS1中的Repeater 421中，以使得Repeater 421再将业务请求转发至主叫中转终端MS1中的BB 422。
步骤34：宽带模块将业务请求发送至宽带基站。
主叫中转终端的宽带模块接收到业务请求后，将该业务请求发送至宽带基站，以使得业务请求能够通过宽带系统传输至被叫终端所在的独立网络中。如图4所示，Repeater 421接收到主叫终端MS2发送的业务请求，并将该业务请求转发到BB 422中，然后BB 422再将业务请求发送到宽带基站41，以实现工作在DMO模式下的主叫终端发送的业务请求能够通过宽带系统传输到其他独立网络中。
步骤35：宽带基站将业务请求发送至被叫中转终端中的宽带模块。
在宽窄带融合网络中配置相同的窄带系统以及宽带系统，即宽窄带融合网络中的终端都属于同一窄带组，终端中的宽带模块都属于同一宽带组；例如，如图4所示，窄带组G1(图中未标识)包括MS2，MS4，MS6以及MS8，宽带组G2(图中未标识)包括MS1，MS3，MS5以及MS7；可以理解地，工作在中继模式的终端的窄带模块也可配置与G1不同的窄带组，例如，窄带组G3，其能够接收并转发窄带组G3下的主叫终 端的业务请求至该宽窄带融合系统中的窄带组G1中，以建立不同窄带系统间的通信连接。
宽带基站在接收到主叫多模终端转发的业务请求后，将该业务请求发送到宽窄带融合系统中的宽带组下的所有具有中转功能的终端的宽带模块，也就是将业务请求发送到所有独立网络下的所有具有中转功能的终端的宽带模块中。
步骤36：被叫中转终端中的宽带模块对业务请求进行解析，得到业务信息。
主叫终端发送的业务请求可包括业务信息，被叫中转终端的宽带模块在接收到业务请求后，对该业务请求进行解析，得到该业务信息，该业务信息可包括业务类型、主叫终端的地址以及目的地址。
进一步地，主叫终端可发起个呼业务或者组呼业务，即其可对某个被叫终端进行单独呼叫，也可对窄带组下的所有被叫终端发起组合呼叫，即业务信息中包含的目的地址可为某个终端的个地址，与可以为一个窄带组的组地址。
主叫终端在进行个呼业务时，主叫终端发送的业务请求中包含被叫终端的地址，如图4所示，主叫终端MS2预向终端MS6发起个呼业务，业务请求中携带终端MS6的地址，宽带基站41在接收到主叫中转终端MS1转发的业务请求后，再通过宽带系统将业务请求发送到宽带组G2下的所有具有中转功能的终端，即窄带模块工作在中继模式的终端，将业务请求发送到终端MS3的BB 432、终端MS5的BB 442以及终端MS7的BB 452，然后终端MS3、MS5以及MS7再识别业务请求中的被叫终端MS6的地址，以建立主叫终端MS2与被叫终端MS6的个呼业务。
类似地，主叫终端在进行组呼业务时，主叫终端发送的业务请求中包含被呼叫的窄带组的组地址，如图5所示，主叫终端MS2预向窄带组G1下的所有工作在DMO模式下的终端发起组呼业务，业务请求中携带窄带组G1的组地址；具体地，主叫终端MS2预向窄带组G1下的所有被叫终端(即被叫终端MS4、MS6以及MS8)发送组呼业务，宽带基站41在接收到主叫中转终端MS1发送的业务请求后，同样将业务请求发送到宽带组G2下的被叫中转终端MS3的BB 432、被叫中转终端MS5的BB 442以及MS7的BB 452，然后被叫中转终端MS3、MS5以及MS7识别业务请求中的窄带组G1的组地址，从而建立主叫终端MS2与窄带组G1下的被叫终端MS4、MS6以及MS8的组呼业务。
在一具体的实施例中，主叫终端的业务类型可包括语音业务与短信业务，在主叫终端发起短信业务时，其发送的业务请求中包括业务类型、主叫终端的地址以及被叫终端的目的地址。
而在主叫终端发起语音业务时，其发送的业务请求只包括业务类型以及目的地址，此时主叫终端发送的业务请求中不携带自身的地址，以降低业务请求携带的数据量，提高传输效率；此外，为了让被叫终端获取到主叫终端的地址，以便能够在语音通话时显 示出主叫终端的地址，并在与主叫终端进行语音通话时进行话语权切换操作，主叫终端在建立业务连接后可通过间隔预设数量的数据帧发送其地址至被叫终端中的方式，使得被叫终端获取到主叫终端的地址，可以理解地，预设数量可根据实际情况进行设置。
在一具体的实施例中，主叫终端可在向被叫终端发送的数据包中携带自身的地址，数据包可包含18个数据帧，前1-17个的数据帧可携带语音通话的内容信息，第18个数据帧可携带其他信息，此时主叫终端可在每个数据包的第18个数据帧中携带自身的地址，也就是主叫终端间隔18个数据帧就发送主叫终端的地址至被叫终端，以使得被叫终端能够获知主叫终端的地址。在其他实施例中，主叫终端还可采用偷帧的形式将自身的地址发送至被叫终端，也就是说，主叫终端还可在数据包的前1-17个数据帧中任意选择半个数据帧来携带主叫终端的地址，例如，可在第11个数据帧的前半帧中携带主叫终端的地址，然后再发送至被叫终端。
步骤37：宽带模块将业务信息发送至被叫中转终端中的窄带模块。
被叫中转终端的宽带模块解析出业务信息后，再将解析出的业务信息发送到自身的窄带模块中，以使得被叫中转终端的窄带模块对业务信息进行判断，根据业务信息中包含的目的地址判断是否对该业务请求进行转发，即是否建立其所属网络下的终端与主叫终端之间的业务连接。具体地，在目的地址为单个终端时，即主叫终端发起个呼业务时，接收到业务请求的终端的窄带模块对该目的地址进行判断，判断该目的地址对应的被叫终端是否属于该终端所在的独立网络中，若该被叫终端与其在同一独立网络中，则窄带模块将该业务请求转发至该被叫终端中；若被叫终端不在该终端所在的独立网络中，则窄带模块不转发该业务请求。可以理解地，在主叫终端发起组呼业务时，此时目的地址为窄带组的组地址，所有窄带模块都对该业务信息进行转发。
步骤38：在窄带模块的工作模式为中继模式时，窄带模块发起与业务信息对应的业务请求，以建立主叫终端与被叫终端之间的业务连接。
在业务信息中包含的目的地址对应的被叫终端在该终端所在的独立网络中时，或者目的地址为窄带组地址时，如果接收到业务请求的终端中的窄带模块工作在中继模式，即该终为具有中转能力的被叫中转终端时，其窄带模块向目的地址对应的被叫终端发送该业务请求。
可以理解地，如果接收到业务请求的终端的窄带模块不工作在中继模式，例如，窄带模块工作在DMO模式，则该终端不具有中转功能，此时该终端中的窄带模块在对业务信息进行解析后，不再对该业务请求进行转发。
请参阅图6，图6是本申请提供的主叫终端、主叫中转终端、宽带基站、被叫中转终端以及被叫终端之间的交互示意图，主叫终端将业务请求发送至主叫中转终端的窄带模块中，然后主叫中转终端的工作在中继模式下的窄带模块将该业务请求转发至自身的宽带模块，宽带模块再将业务请求发送到宽带基站，以使得宽带基站将该业务请求通过 宽带系统发送到宽窄带融合系统中的所有中转终端的宽带模块中，然后每个中转终端的宽带模块再对该业务请求进行解析，并将解析出来的业务信息转发到自身的窄带模块，然后窄带模块基于业务信息中的目的地址向相应的被叫终端发送业务请求，从而建立主叫终端与被叫终端之间的业务连接。
本实施例所提供的宽窄带融合系统包含多个独立网络，每个独立网络下的主叫终端都可通过与其连接的主叫中转终端将自身的业务请求转发到其他独立网络下的被叫中转终端，然后通过其他独立网络下的被叫中转终端再次转发业务请求至相应的被叫终端，从而建立不同独立网络中的终端之间的业务连接，以便完成主叫终端发起的组呼业务或者个呼业务，能够实现终端间的通信信号的多跳，进而提高了终端间的通信距离，可应用在对通信距离要求较高的场景中。
