- the identifier information included in the fault weakening base station list is used to record the base station entering the fault weakening state. Further, if the identifier information is included in the fault weakening base station list, if the network address is included, the network address is used. The identification information is also used to achieve recovery of communications in the base station entering the fault weakened state.
- the base station path information may be constructed, and the base station path information constructed according to the identifier information is stored in the fault weakening base station list.
- the constructed base station path information may be empty, and is to be continuously updated in the diffusion of the weakened base station list in the subsequent fault, thereby obtaining the base station path information that is consistent with the diffusion path; on the other hand, the constructed base station path information may only include the present The base station identifier of the base station, and the base station or the core network in which the subsequent diffusion takes place can continuously improve the base station path information.
- step S250 the diffusion fault weakens the base station list, and the base station or the core network through which the fault weakening base station list is spread updates the base station path information included in the base station.
- the faulty weakened base station list is spread to the neighboring base station or the core network, so that the fault weakened base station list is spread in the broadband cluster system, and then the base station and the core network maintenance fault weakening base station list in the broadband cluster system are maintained. .

Therefore, it can still receive the call initiated by the user terminal in the cell. If the called user terminal of the call is also located in the cell, the base station remains It is possible to establish communication between the user terminal that initiated the call and the called user terminal.

- the identifier information in the fault weakening base station list is associated with the base station user information in addition to the base station user list. Therefore, after determining the base station user list where the called user terminal is located and obtaining the associated identification information, The corresponding base station path information will be obtained. The obtained base station path information is used by the base station to resume communication, and the user terminal that initiates the call is established with the called user terminal.
- the base station is used as the source base station, and path extraction is performed according to the source base station and the target base station to obtain a path marked for communication between the base station and the target base station.

- step S530 the network address of the target base station is communicated with the target base station to determine whether the communication is successful. If yes, the process goes to step S550, and if no, the process goes to step S170.
- a communication request message is initiated according to the network address of the target base station to establish communication with the target base station. If the base station successfully communicates with the target base station through the network address of the target base station, the communication between the user terminal and the called user terminal can be directly performed; if the base station fails to communicate with the target base station through the network address of the target base station, it needs to pass The base station path information recovers communication between the base station and the target base station.

体现本发明特征与优点的典型实施方式将在以下的说明中详细叙述。应理解的是本发明能够在不同的实施方式上具有各种的变化,其皆不脱离本发明的范围,且其中的说明及图示在本质上是当作说明之用,而非用以限制本发明。
如前所述的,对于LTE集群通信,任一基站都可能进入故障弱化状态,即其与核心网之间的S1链路异常,此时,该基站仅能够为其所对应小区中包含的用户终端提供服务,并且与其它相邻基站之间存在着通过X2链路通信的可能性,但由于S1链路异常而无法与核心网通信,从而通信成功的概率和通信范围均大大降低。
鉴于此,特提出了一种故障弱化下基站通信的恢复方法,以在基站进入故障弱化状态的前提下仍然能够保证通信成功的概率和通信范围的扩大,从而保证了基站进行通信的可靠性。
在一个实施例中,具体的,该方法如图1所示,包括:
步骤S110,接收核心网返回的和/或相邻基站发送的故障弱化基站列表,接收到的故障弱化基站列表包含:故障弱化基站的标识信息和标识信息对应的基站路径信息。
宽带集群系统中基站将接收到故障弱化基站列表,故障弱化基站列表用于为宽带集群系统中本基站或者其它进入故障弱化状态的基站中通信的恢复提供所需要的基站路径或者目标基站的网络地址。
接收的故障弱化基站列表是通过核心网和/或相邻基站扩散到本基站的,因此,故障弱化基站列表中记录了其扩散所途经的故障弱化基站的标识信息、核心网的标识信息,并且每一故障弱化基站的标识信息都有对应的基站路径信息。
其中,基站路径信息中记录了从对应的故障弱化基站到达相邻基站的路径。
一方面,由于本基站进入故障弱化状态,在核心网所得到的故障弱化基站列表中记录了本基站,因此,
核心网将会各相邻基站向本基站返回故障弱化基站列表,以便于进入故障弱化状态的本基站能够恢复与核心网或者其它基站之间的通信;另一方面,任意进入故障弱化状态的基站构建的故障弱化基站列表都是在整个宽带集群系统中扩散的,因此,本基站会接收到相邻基站扩散的故障弱化基站列表,此时,中断通信的本基站通过接收的故障弱化基站列表至少能够获知其相邻基站,以恢复其与相邻基站之间的通信。
需要明确指出的是,故障弱化基站列表被任一进入故障弱化状态的基站构建后扩散,其所进行的扩散终止于核心网。
步骤S130,基站自身进入故障弱化状态时,在故障弱化基站列表中更新标识信息对应的基站路径信息和添加自身的标识信息。
如果基站自身进入了故障弱化状态,则在接收的故障弱化基站列表中,对每一基站路径信息进行更新,并加入自身的标识信息。
步骤S150,存储和扩散故障弱化基站列表。
在完成了故障弱化基站列表的更新之后,将存储和扩散此故障弱化基站列表。一方面,通过进行的故障弱化基站列表来实现本基站的通信,另一方面,通过进行的故障弱化基站来不及的扩散来实现故障弱化基站列表的维护,以便于获得最终的故障弱化基站。
步骤S170,通过存储的故障弱化基站列表恢复本基站的通信。
本基站接收到故障弱化基站列表,能够从故障弱化基站列表中获取到所需要的基站路径信息,进而按照基站路径信息所提供的基站路径恢复通信。
例如,本基站虽无法通过S1链路与核心网通信,进而也无法在核心网的控制下实现其与其它基站之间的通信。但是本基站根据故障弱化基站列表中的基站路径信息建立与相邻基站之间的X2链路,从而通过相邻基站与核心网通信,并在核心网的作用下实现与其它基站之间的通信。
本基站通过如上所述的通信恢复过程,成功实现了与其它基站和/或核心网的通信,进而即便进入故障弱化状态,各种通信业务也能够顺利进行,并且对于本基站下的各用户终端而言,仍然能够通过本基站提供的服务实现与其它用户终端之间的呼叫和应答。
在一个实施例中,如图2所示,如上所述的方法还包括:
步骤S210,基站在进入故障弱化状态时获取自身的标识信息。
标识信息用于唯一标识基站或者核心网。基站的标识信息包括基站标识(基站ID)和/或基站所在的网络地址(基站IP);核心网的标识信息包括核心网标识。
宽带集群系统中任一基站进入故障弱化状态时,都将触发标识信息的获取,以对基站进入故障弱化状态进行快速响应。
步骤S230,根据标识信息构建故障弱化基站列表。
宽带集群系统中进入故障弱化状态的基站构建故障弱化基站列表,构建的故障弱化基站列表至少包括本基站的标识信息,
因此,故障弱化基站列表在构建时虽然只包括了本基站的标识信息,但是,故障弱化基站列表会通过扩散算法不断更新对应的基站路径信息,并记录所途经的故障弱化状态下的基站。
需要说明的是,故障弱化基站列表中包含的标识信息用于记录进入故障弱化状态的基站,更进一步的,在故障弱化基站列表中标识信息如果包括了网络地址,则在网络地址的作用下该标识信息也用于实现进入故障弱化状态的基站中通信的恢复。
进一步的,在故障弱化基站列表的构建中除了本基站的标识信息,还可构建基站路径信息,并在故障弱化基站列表中根据标识信息对应存储构建的基站路径信息。
其中,构建的基站路径信息可为空,以待后续故障弱化基站列表的扩散中不断更新,进而得到与扩散路径相符的基站路径信息;另一方面,构建的基站路径信息也可仅包含了本基站的基站标识,后续扩散所途径的基站或核心网可不断在此完善基站路径信息。
但无论构建的基站路径信息为何种形式,其都是标记了以本基站为源基站到达其它基站或核心网的路径。
步骤S250,扩散故障弱化基站列表,故障弱化基站列表被扩散所途经的基站或核心网更新自身包含的基站路径信息。
在构建了故障弱化基站列表之后,向相邻基站或者核心网扩散故障弱化基站列表,使得故障弱化基站列表在宽带集群系统中扩散,进而通过宽带集群系统中各基站和核心网维护故障弱化基站列表。
具体的,随着故障弱化基站列表的扩散,对应的扩散范围在不断地扩大,途经的任意基站或核心网都对接收的故障弱化基站列表更新基站路径信息之后,再继续进行故障弱化基站列表的扩散。
其中,故障弱化基站列表中基站路径信息的更新是根据向故障弱化基站列表中的各种基站路径信息标记所经过的基站或核心网。基站路径信息是与标识信息相对应的,因此,基站路径信息记录了标识信息对应的基站与其它基站或核心网之间的路径。
需要说明的是,故障弱化基站列表的扩散指的是向所有的相邻基站或核心网发送故障弱化基站列表,如果发送的故障弱化基站列表是从一相邻基站接收到的,在更新后所进行的扩散是向除了前述发送故障弱化基站列表的相邻基站之外的其它相邻基站或核心网发送更新后的故障弱化基站列表。
如上所述的方法是一个运行于一进入故障弱化状态的基站的实施例,宽带集群系统中任意基站进入故障弱化状态时都会进行故障弱化基站列表的构建和扩散,也都能够通过接收的故障弱化基站列表来恢复通信。
在一个实施例中,如图3所示,步骤S130之后,该方法还包括:
步骤S310,获取自身的基站用户表,基站用户表记录控制的小区中存在的用户终端。
宽带集群系统包括核心网、基站和位于基站控制的小区的用户终端,每一基站都控制着一个或者多个小区,以为小区中的用户终端提供服务。基站用户表记录了基站控制的小区中存在的用户终端。
步骤S330,将基站用户表存储于故障弱化基站列表,并与自身的标识信息关联。
在故障弱化基站列表中进行基站用户表的存储,并使存储的基站用户表关联于标识信息。因此,通过故障弱化基站列表,既能够获知进入故障弱化状态的基站恢复通信的路径,也能够获知哪些用户终端随着基站进入故障弱化状态而中断通信,进而使得这些中断通信的用户终端也能够发起呼叫或者进行应答。
进一步的,在一个实施例中,目标基站为故障弱化基站,如图4所示,步骤S170包括:
步骤S171,接收用户终端发起的呼叫,根据呼叫在接收的故障弱化基站列表中对基站用户表进行呼叫查找被叫用户终端。
本基站进入故障弱化状态时能够与控制的小区中用户终端通信,因此,其仍然能够接收得到小区中用户终端发起的呼叫,此呼叫的被叫用户终端如果也位于该小区中,则本基站仍然能够建立发起呼叫的用户终端和被叫用户终端之间的通信。
但是,如果被叫用户终端并不位于该小区,则本基站在对呼叫所进行的响应中,对故障弱化基站列表中存储的基站用户表进行呼叫查找,即,呼叫查找出与当前接收的呼叫对应的被叫用户终端。
步骤S172,在查找得到被叫用户终端时根据被叫用户终端所在基站用户表关联的标识信息得到目标基站;
由呼叫查找得到的被叫用户终端得到所在的基站用户列表,进而由此基站用户列表与标识信息之间的关联得到标识信息,此标识信息所标识的基站即为响应呼叫建立与被叫用户终端之间通信的目标基站。
被叫用户终端位于目标基站控制的小区中。
步骤S173,在故障弱化基站列表中根据基站自身的标识信息得到对应的基站路径信息,并按照目标基站在基站路径信息中提取基站路径。
如前所述的,故障弱化基站列表中标识信息除了与基站用户列表关联之外,还对应于基站路径信息,因此,在确定被叫用户终端所在的基站用户列表并得到关联的标识信息之后,将得到对应的基站路径信息。得到的基站路径信息用于本基站恢复通信,为发起呼叫的用户终端建立与被叫用户终端。
具体的,在得到的基站路径信息中,以本基站为源基站,按照源基站和目标基站进行路径提取,以得到标记了本基站和目标基站之间进行通信的路径。
步骤S175,按照基站路径建立链路,恢复与被叫用户终端所在基站之间的通信。
可按照基站路径建立基站之间的X2链路,以恢复本基站和目标基站之间进行通信的路径,进而实现任一用户终端与被叫用户终端之间的通信。
通过如上所述的过程,使得进入故障弱化状态的基站也能够顺畅实现其用户终端与其它用户终端,甚至于其它故障弱化状态的基站下的用户终端之间的通信,对于用户终端而言,屏蔽了故障弱化的影响。
如上所述的过程是应用于发起呼叫的用户终端所在基站以及被叫用户终端所在基站均为故障弱化状态的场景下,在一个实施例中,此场景可以是核心网故障的场景。例如,核心网故障而导致宽带集群系统中所有基站进入故障弱化状态。
在一个实施例中,核心网和被叫用户终端所在的基站均未发生故障,如图5所示,如上所述的方法还包括:
步骤S410,在接收的故障弱化基站列表中根据基站自身的标识信息得到对应的基站路径信息。
在接收用户终端发起的呼叫并在故障弱化基站进行呼叫查找的过程中,如果没有呼叫查找得到相应的被叫用户终端,则说明被叫用户终端并不存在于故障弱化状态下的基站所控制的小区中,需要在核心网的控制下对其它基站控制的小区进行寻呼。因此,首先在接收的故障弱化基站列表中获取自身标识信息所对应的基站路径信息。
步骤S430,由基站路径信息提取目的为核心网的基站路径。
以本基站为源基站,提取目的为核心网的基站路径,即所提取得到的基站路径以本基站为起始,以目标基站为终止的基站路径。
步骤S450,按照基站路径建立与核心网之间的链路,恢复与核心网之间的通信。
在此场景下,本基站与核心网之间的链路中断,但是核心网仍然正常运行,因此将通过提取的基站路径来建立本基站与核心网之间的链路。
步骤S470,通过核心网进行用户终端和被叫用户终端之间的通信。
通过核心网在其它基站控制的小区寻找到被叫用户终端,进而建立用户终端与被叫用户终端之间的通信。其中,被叫用户终端所在的基站是某一未进入故障弱化状态的基站。
如上所述的过程应用于发起呼叫的用户终端所在基站进入故障弱化状态,而核心网和被叫用户终端所在基站均正常运行的场景中。
在一个实施例中,标识信息包括网络地址,如图6所示,如上所述的方法还包括:
步骤S510,根据被叫用户终端所在基站用户表关联的标识信息得到目标基站后,从目标基站的标识信息得到目标基站的网络地址。
如前所述的,标识信息除了包括基站标识之外,还包括了网络地址。在此实施例中,基站路径信息与基站标识相对应,并且基站用户列表也是关联于基站标识的。
本基站进入故障弱化状态后,通过呼叫查找得到响应呼叫所对应的目标基站,即得到目标基站所对应的基站标识,此时,将由所在的标识信息得到相应的网络地址。
步骤S530,通过目标基站的网络地址与目标基站通信,判断通信是否成功,若为是,则进入步骤S550,若为否,则进入步骤S170。
根据目标基站的网络地址发起通信请求消息,以建立与目标基站之间的通信。如果本基站通过目标基站的网络地址与目标基站通信成功,则可直接进行用户终端和被叫用户终端之间的通信;如果本基站通过目标基站的网络地址与目标基站通信不成功,则需要通过基站路径信息恢复本基站和目标基站之间的通信。
步骤S550,通过目标基站进行用户终端和被叫用户终端之间的通信。
通过如上所述的过程,使得进入故障弱化状态的本基站优先使用网络地址进行通信,而基站路径信息则作为本基站恢复通信的备选手段,对于本基站的通信恢复而言,多种恢复手段的存在保证了通信的健壮性。
在一个实施例中,标识信息包括基站标识,该方法如图7所示,还包括:
步骤S610,在接收到相邻基站发送的故障弱化基站列表时,在故障弱化基站列表将自身的基站标识添加至基站路径信息,并存储自身的标识信息。
基站路径信息包括基站标识和/或核心网标识,其中,核心网标识可作为一特殊的基站标识。换而言之,基站路径信息顺次记录其扩散所途经的各基站和核心网,此记录是通过基站标识来实现的。
任一故障弱化基站列表都是在基站进入故障弱化状态时构建,其内容通过扩散进行更新,并且进行的扩散和更新将终止于核心网。换而言之,核心网对于扩散到其自身的故障弱化基站列表,将进行故障弱化基站列表中各基站路径信息的更新,即在基站路径信息中顺次添加核心网标识,并且在故障弱化基站列表将其本身为作一特殊的基站进行相应标识信息和基站路径信息的添加,即添加核心网标识,构建与核心网标识关联的基站路径信息。
其中,基站路径信息用于记录由核心网返回一故障弱化状态的基站所对应的基站路径。
核心网在完成了如上所述的故障弱化基站列表的更新之后,将存储此故障弱化基站列表,以便于与其中任一进入故障弱化状态的基站恢复通信。
与此同时,核心网还将根据此故障弱化基站列表中记录的基站标识和对应的基站路径信息向各故障弱化状态下的基站返回此故障弱化基站列表,进而使得各故障弱化状态下的基站保存核心网返回的故障弱化基站列表。
通过此过程,使得故障弱化状态的基站能够保存最为全面的故障弱化基站列表,以为其恢复通信提供保障,并且由于将核心网作为一特殊的基站处理,因此更加方便了与核心网之间通信的恢复。
本基站在故障弱化状态下除了构建故障弱化基站列表并扩散,接收由核心网返回的故障弱化基站列表之外,还会接收到相邻基站所发送的故障弱化基站列表。
区别于核心网返回的故障弱化基站列表,此故障弱化基站列表正处在扩散过程中,本基站是扩散过程中途经的一个基站,在此情况下,添加自身的基站标识添加至各基站路径信息,并在此故障弱化基站列表中存储自身的标识信息,以便于在后续的扩散过程中得到本基站到其它基站或者核心网的基站路径信息。
步骤S630,获取自身的基站用户表,将基站用户表存储于故障弱化基站列表,并与自身的标识信息关联。
如图8所示,本基站动态生成自身的基站用户表,如前所述的,本基站自身的基站用户表与相应的标识信息关联存储于故障弱化基站列表中,以方便其它基站能够通过此故障弱化基站列表找到本基站控制的小区下存储的用户终端。
具体的,任一基站均是为处于其覆盖范围,即小区的用户终端提供服务的,因此,任一基站所控制的小区大都存在着多个用户终端,对于故障弱化基站列表而言,在记录进入故障弱化状态的基站所对应标识信息的同时,还将动态生成关联的基站用户表,基站用户表记录了进入故障弱化状态的基站中存在的用户终端。
完成基站用户表存储的故障弱化基站列表将继续进行扩散,并存储在本基站中。
通过如上所述的过程,使得本基站即便进入故障弱化状态,也能够为所在宽带集群系统中其它进入故障弱化状态的基站维护故障弱化基站列表,而并不仅限于其自身故障弱化基站列表的构建,进而极大地提高了宽带集群系统中通信的健壮性。
进一步的,在本实施例中,该方法如图9所示,还包括:
步骤S710,判断接收到的相邻基站发送的故障弱化基站列表所对应的扩散次数是否达到预设限值,若为是,则进入步骤S730,若为否,则进入步骤S610。
扩散次数用于控制故障弱化基站列表在宽带集群系统中的扩散。故障弱化基站列表针为每一个记录的进入故障弱化状态的基站标记了扩散中途径的基站或者核心网,以便于提供此进入故障弱化状态的基站到达标记的任意基站或核心网所需要的路径,但是,对于跳数过多,例如跳数超出了预设限值的路径将是不可用的,
因此,需要通过扩散次数进行控制。在实际运行中,扩散次数所对应的数值将根据具体的组网配置情况而确定。
在一个实施例中,在构建故障弱化基站列表时,将配置跳计数器,并且在所进行的故障弱化基站列表的扩散中,将跳计数器和故障弱化基站列表一并进行扩散,随着故障弱化基站列表所经过的每一跳传输,都将触发跳计数器时行更新,例如,每经过一跳时跳计数器中的数值进行自减运算,而跳计数器的初始值为预设限值。
通过跳计数器进行扩散次数的控制,如果跳计数器所对应的数值为0,则说明扩散次数达到了预设限值,因此,应当将故障弱化基站列表丢弃。
步骤S730,丢弃故障弱化基站列表。
通过如上所述的过程,将有效保障了故障弱化基站列表中基站路径信息的有效性,进而使得通过故障弱化基站列表所实现的通信恢复能够随着基站通信的需要随时进行。
在另一个实施例中,接收故障弱化基站列表的基站未发生故障,步骤S110之后,如图10所示,如上所述的方法还包括:
步骤S810,根据自身的标识信息进行故障弱化基站列表中基站路径信息的更新。
故障弱化基站列表的扩散中,基站都会接收到故障弱化基站列表,如果基站未发生故障,此时,将首先根据自身的标识信息进行故障弱化基站列表中各基站路径信息的更新,以在各基站路径信息中标记本基站。
需要说明的是,本实施例中,对扩散的故障弱化基站列表进行接收的基站将是能够正常进行通信,未进入故障弱化状态的基站。
步骤S830,扩散更新的故障弱化基站列表。
向相邻基站或核心网扩散更新的故障弱化基站列表。具体的,如果接收到故障弱化基站列表的基站并不处于故障弱化状态,则其与核心网之间的S1链路正常,能够在对接收的故障弱化基站列表更新后分别传输至核心网和相邻基站。
通过此过程,完成了任意正常进行通信的基站中故障弱化基站列表的更新和扩散,由此将保障了任意故障弱化基站列表的维护。
在一个实施例中,还相应的提供了一种故障弱化基站通信的恢复方法,如图11所示,包括如下步骤:
步骤S1010,自身未发生故障时,接收扩散的故障弱化基站列表,根据自身的标识信息进行故障弱化基站列表中基站路径信息的更新。
任意故障弱化基站列表的扩散中,核心网都会接收到故障弱化基站列表,核心网均未发生故障,此时,将首先根据自身的标识信息进行故障弱化基站列表中各基站路径信息的更新,以在各基站路径信息中分别标记核心网。
因此,在故障弱化基站列表的扩散中,进行故障弱化基站列表接收的通信设施除了基站之外,还包括了核心网,核心网在故障弱化基站列表中视为特殊的基站。
例如,对于包括了基站标识和网络地址、核心网标识的标识信息而言,故障弱化基站列表可如下表形式:
表1
其中,基站IP1和基站IP2均基站所对应的网络地址,而基站ID1和基站ID2则为基站标识,核心网ID1为核心网标识。
需要说明的是,核心网将作为一种特殊的,未进入故障弱化状态的基站。
步骤S1030,向核心网自身控制下进入故障弱化状态的基站返回更新的故障弱化基站列表。
如前所述的,核心网接收到故障弱化基站列表,并对此进行更新,但是需要特别说明的是,核心网故障时其与各基站的S1链路都中断,各基站都进入故障弱化状态,并且核心网将不会接收到扩散的故障弱化基站,在故障弱化基站列表的作用下,各相邻基站之间通过X2链路进行通信,而不存在核心网原本的功能。
通过此过程,在LTE集群通信中,相对一故障弱化基站,其它基站和核心网对其进入故障弱化状态时行了快速响应,进而相互配合实现了故障弱化状态下通信的快速恢复,极大提高了鲁棒性。
在另一个实施例中,如图12所示,该方法还包括:
步骤S1110,核心网在未成功寻呼时根据存储的故障弱化基站列表得到被叫用户终端所在基站以及对应的标识信息、基站路径信息。
基站在与核心网之间链路正常时,接收用户终端发起的呼叫,并通过与核心网之间的链路将呼叫转发至核心网。
此时,核心网将进行被叫用户终端的寻呼。
具体的,所指的基站是自身能够正常进行通信的基站,其与核心网之间能够通信,并且核心网也未存在故障。基站所接收的用户终端发起的呼叫是指本基站控制的小区中任意用户终端发起的呼叫。
如果用户终端发起呼叫的被叫用户终端未在本基站控制的小区中,则通过本基站与核心网之间的链路,例如,S1链路,将呼叫转发至核心网中,以通过核心网进行被叫用户终端的寻呼。
核心网通过与其它基站的通信进行寻呼,以在其它基站控制的小区中寻找被叫用户终端,如果未成功寻找到被叫用户终端,则说明当前正常进行通信的基站控制的小区下不存在此被叫用户终端,需要在已经进入故障弱化状态的基站控制的小区寻找此被叫用户终端。
在此,由于核心网存储了故障弱化基站列表,并且故障弱化基站列表中记录的任意基站都有对应的基站用户表,因此可通过核心网自身存储的故障弱化基站列表实现进入故障弱化状态的基站控制的小区中被叫用户终端的查找。
具体的,在故障弱化基站列表中,对所有基站用户表进行查找,以得到包含被叫用户终端的基站用户表,进而由得到的基站用户表得到关联的标识信息,根据这一标识信息也得到了对应的基站路径信息。
其中,所得到的关联的标识信息所标识的基站即为被叫用户终端所在的进入故障弱化状态的基站,被叫用户终端存在于这一基站所控制的小区中;所得到的基站路径信息用于构建核心网与这一基站之间进行通信的链路。
步骤S1130,通过标识信息中的网络地址或基站路径信息与被叫用户终端所在基站通信,以进行发起呼叫的用户终端和被叫用户终端之间的通信。
如前所述的,经由标识信息能够得到基站路径信息,而在一个实施例中,标识信息除了包括基站标识之外,还包括了基站所在的网络地址。因此,对于由故障弱化基站列表得到了标识信息和基站路径信息的核心网而言,其可对标识信息中的网络地址或者基站路径信息择一进行被叫用户终端所在基站之间的通信。
一方面,根据标识信息中的网络地址,核心网直接发起与被叫用终端所在基站之间的通信;
另一方面,核心网由基站路径信息提取得到核心网与被叫用户终端所在基站之间的基站路径,以获知从核心网达到被叫用户终端所在基站所需要经过的基站,进而通过S1链路以及基站之间X1链路构建核心网与被叫用户终端所在基站之间的链路。
在优选的实施例中,优先使用网络地址进行通信,在通过网络地址所进行的通信不成功时,再使用基站路径信息进行通信。
通过如上所述的过程,用户终端需要与其它小区的用户终端进行通信时,如果所在基站与核心网之间链路正常,而被叫用户终端所在基站进入故障弱化状态,则可通过核心网中存储的故障弱化基站列表来实现用户终端与被叫用户终端之间的通信,进而即便宽带集群系统中即便存在进入故障弱化状态的基站,也能够维护宽带集群系统中所有用户终端的通信,进而极大提高了宽带集群系统中通信的建壮信。
在一个实施例中,步骤1030的具体过程包括:按照故障弱化基站列表中的标识信息向相应的基站返回核心网自身更新的故障弱化基站列表。
如前所述的,故障弱化基站列表所进行的扩散终止于核心网,并且核心网被视为特殊基站,因此,接收到故障弱化基站列表的核心网在完成基站路径信息的更新,并将核心网标识作为新的标识信息来添加至故障弱化基站列表之后,向故障弱化基站列表中记录的进入故障弱化状态的各基站返回此故障弱化基站列表,以将此故障弱化列表存储在进入故障弱化状态的各基站中。
通过如上所述的步骤,使得宽带集群系统中所进入故障弱化状态的基站都能够得到最终所维护的故障弱化基站列表,保证了进入故障弱化状态的基站能够通过故障弱化基站列表恢复通信,进而不受其当前所发生的S1链路故障的影响。
在一个实施例中,接收的故障弱化基站列表至少为两个,该方法如图13所示,还包括:
步骤S1210,核心网分别从接收的至少两个故障弱化基站列表提取得到相同标识信息对应的至少两个基站路径信息。
对于核心网而言,由于其与多个基站之间通过S1链路进行通信,因此,能够接收到多个基站通过S1链路所送达的至少两个故障弱化基站列表,并需要对所接收的至少两个故障弱化基站列表进行整合,以得到最终的故障弱化基站列表。
由于扩散的路径不同,至少两个故障弱化基站列表中,相同标识信息对应的至少两个基站路径信息也各不相同,需要对基站路径信息进行取舍,以留存跳数最小的基站路径信息。
步骤S1230,在提取的至少两个基站路径信息中保留跳数最小的基站路径信息,丢弃其它路径信息,以合并接收的至少两个故障弱化基站列表。
由任意基站到达目标基站,或者由任意基站到达核心网所需要经过的基站数目即为跳数。在为相同标识信息所提取的至少两个基站路径信息中,仅保留跳数最小的基站路径信息,即保留最短基站路径所对应的基站路径信息,以实现接收的至少两个故障弱化基站列表中基站路径信息的筛选。
在完成了至少两个故障弱化基站列表中基站路径信息的筛选之后,进行合并即可,从而得到最终的故障弱化基站列表,由此所得到的故障弱化基站列表中,标识信息对应一基站路径信息,并且此基站路径信息标识了宽带集群系统中最短基站路径。
可以理解的,整个宽带集群系统中,进入故障弱化状态的基站都构建了其所对应的故障弱化基站列表,并且为通过扩散而到达本基站的故障弱化基站列表更新基站路径信息和添加自身的标识信息。
核心网作为故障弱化基站列表扩散的终止节点,将有必要处理所有的故障弱化基站列表,以得到最终可供其自身以及进入故障弱化状态的各基站使用,以提高故障弱化基站列表的有效性。
下面结合具体的场景来阐述如上所述的方法。在一个实施例中,以核心网故障为例进行说明。
如图14所示,宽带集群系统中,核心网故障时,各基站与核心网之间S1链路异常,因此各基站都进入故障弱化状态。
进入故障弱化状态的各基站之间并无法获知相互的状态和网络地址,因此,进入故障弱化状态的各基站之间只能够通过故障弱化基站列表的构建和扩散过程通知进入故障弱化状态的其它基站自己的网络地址或者基站路径,并通过核心网送达的故障弱化基站列表得到与进入故障弱化状态的其它基站或者核心网进行通信的网络地址或者基站路径。
与之相对应的,进入故障弱化状态的其它基站在获取也能够通过接收到的故障弱化基站列表恢复通信,从而这些进入故障弱化状态的基站之间,以及与核心网之间都能够恢复通信。
在此基础上,通过这些进入故障弱化状态的基站之间的通信恢复,使得用户终端之间即便所在基站进入故障弱化状态,也能够保证最大的通信成功率和通信范围。
又例如,如图15所示的,基站1与核心网之间的S1链路出现问题,并且基站2与核心网之间的S1链路出现问题,但是核心网正常,基站3与核心网之间的S1链路正常。
在此场景下,基站1和基站2进入故障弱化状态,基站3和核心网正常运行。
此时,通过如前所述的故障弱化基站列表的构建和扩散,进入故障弱化状态的基站通过正常运行的其它基站联系到核心网,例如,对于基站1而言,其根据故障弱化基站列表可获知其可联系到核心网的基站路径,即基站1—〉基站2—〉基站3—〉核心网,其中,基站之间的链路通过X2链路实现,基站与核心网之间的链路通过S1链路实现。
相应的,故障弱化基站列表由进入故障弱化状态的基站构建,并向各基站扩散。在此扩散中,各基站都会对故障弱化基站列表中的基站路径信息进行更新,并在自身处于故障弱化状态时,向故障弱化基站列表添加标识信息,进而完成故障弱化基站列表的更新,并继续进行故障弱化基站列表的扩散。
自身处于故障弱化状态的基站将存储此故障弱化基站列表,以保证其在接收到核心网送达的最终故障弱化基站列表之前,也能够恢复通信,尽可能地保证通信成功率和通信范围。
当然,故障弱化基站列表的扩散中,未处于故障弱化状态的基站只对故障弱化基站列表进行更新,而并不需要对故障弱化基站列表进行存储。
再例如,在技术的具体实现层面上,将以图16所示的场景进行简要说明。其中,eNB1和eNB2分别对应了两个基站,MME则是对应的核心网网元。
eNB1故障,造成eNB1和MME之间S1链路中断,此时,eNB1只能利用其与eNB2之间的X2链路重新传输S1链路的建立消息,通过eNB2新建和MME的Proxy S1链路,从而实现eNB1和MME之间通信的快速恢复。
在此过程中,MME并不需要感知eNB1故障,对其它基站的链路也不会造成影响,快速对故障所造成的影响进行了恢复。
其中,所涉及的时序过程如图17所示,即图17中步骤1至步骤6所描述的时序过程。具体的,eNB1发现S1链路中断后,首先在已有的X2链路中选择一个正常运行的相邻基站,如eNB2。
eNB1发送X2AP MESSAGE TRANSFER消息,该消息包含有S1SETUP REQ消息。
eNB2收到S1SETUP REQ的X2透传消息后,首先发起一个新的和MME的SCTP连接建立。
SCTP连接建立完成后,eNB2代替eNB1透传S1SETUP REQ。
MME向eNB2回复S1SETUP RSP,此时eNB的代理S1链路建立成功。
eNB2向eNB1发送X2AP MSG TRANSFER消息,该消息用于透传MME发送的S1SETUP RSP。
在上述过程之下,eNB1通过eNB2的X2代理消息,收到S1SETUP RSP后完成了S1链路的恢复,进而恢复基站的服务。
