[0021] 具体实施方式 [0021] DETAILED DESCRIPTION

[0022] 为了使两个SIP实体的任意两个IP地址之间可以实现多个SIP中继群组,SIP实体可以根据IP地址与端口的组合作为判断条件进行划分SIP中继群组,判断条件包括:源IP地址、目的IP地址和目的端口的组合;源IP地址、目的IP地址、源端口和目的端口的组合;源IP地址、目的IP地址和源端口的组合等。 [0022] In order for any two two SIP entities may be implemented between a plurality of SIP trunk group IP address, SIP entities may be divided SIP trunk group, in accordance with conditions determined IP address and port combination as a determination condition comprising: a combination of a source IP address, destination IP address and destination port; source IP address, destination IP address, source port and destination port combination; source IP address, destination IP address and source port combination.

[0023] 1)根据源IP地址、目的IP地址和目的端口的组合作为判断条件进行划分SIP中继群组 [0023] 1) the source IP address, destination IP address and destination port combination will be divided as a judgment condition SIP trunk group

[0024] 请参阅图2,本发明具SIP中继群组的系统包括多个业务模块,每个业务模块可以驻留在不同的硬件实体上,每个业务模块拥有绑定的唯一的本地端口。 [0024] Referring to FIG. 2, the present invention system with a SIP trunk group comprising a plurality of service modules, each service module may reside on different hardware entities, each service module has a unique local port bound . IP地址1、IP地址2 及IP地址η为第一SIP实体对外发送或接收SIP消息的地址,每个IP地址对应多个服务端口(服务端口可以是SIP知名端口5060或是其它可配置的端口),服务端口用于接收及发送SIP消息。 IP address. 1, 2 and the IP address of the IP address of the first SIP address η entity outside sent or received SIP message, each IP address corresponding to a plurality of service ports (SIP service port may be a well-known port 5060 or other configurable ports ), service port for receiving and sending SIP messages. 第一SIP实体与第二SIP实体对接时任意两个IP地址间可以添加多个SIP 中继群组,每个SIP中继群组上的呼叫可以在业务模块上实现负荷分担。 Any two of the first SIP entity when the IP address of the SIP entity and a second plurality of mating between SIP trunk groups can be added, each SIP call on trunk group load sharing may be implemented in the service module.

[0025] 现以第一SIP实体与第二SIP实体互通为例说明。 [0025] Now a first SIP entity to a second SIP entity interworking with an example.

[0026] 当第一SIP实体中的任一业务模块通过任一对外IP地址及端口发起对第二SIP 实体的呼叫时,现以第一SIP实体上的业务模块1以及IP地址2与第二SIP实体上的IP地址4之间进行呼叫来描述: =[0027] 对于第一个呼叫外的SIP消息,其源IP地址为IP地址2,源端口为本地端口1,目的IP地址为第二SIP实体的IP地址4,目的端口为IP地址4中的服务端口n,即SIP消息Via头域中地址填写IP地址2,Contact头域中地址填写IP地址2,端口为本地端口1 ; RequestUri及TO头域中IP地址填写为IP地址4,端口为IP地址4中的服务端口η ;如图2中的SIPTG-I连线所示。 [0026] When any one of the first SIP entity in a service module of any one of the external IP address and port of the second SIP entity initiates a call, is to a first service module and the IP address of the SIP entity 1 and the second 2 the IP address on the SIP entity described call between 4: = [0027] a first call to the outer SIP message, the source IP address is the IP address 2, the source port is a local port, the destination IP address of the second 4 IP address of the SIP entities, the IP address of the destination port in the n service port 4, i.e., SIP message header field address Via fill IP address 2, the address in the Contact header field to fill in 2 IP address, local port port 1; RequestUri and tO header field populated with the IP address IP address 4, the service port is a port in the IP address η 4; shown in FIG. 2 SIPTG-I connection. SIP消息头域及消息体根据SIP协议及具体的应用填写。 SIP message header and the SIP message body and filled in accordance with the particular application. 第二SIP实体在接收到该SIP消息后,根据该消息的源IP地址、目的IP地址及目的端口确认出该呼叫是SIPTG-I上的呼叫。 Second SIP entity after receiving the SIP message, the message source IP address, destination IP address and destination port of the call is a call confirmed on SIPTG-I. 第二SIP实体发送给第一SIP实体的响应消息及后续请求消息按照SIP协议标准实现。 SIP entity to a second entity a first SIP message in response to the subsequent request message and implemented in accordance with the SIP protocol standards. 第二SIP实体发起对第一SIP实体的呼叫也类似于第一SIP实体发起对第二SIP实体的呼叫。 It initiates a call to the second SIP entity a first SIP entity is also similar to the first SIP entity to a second SIP entity initiating the call. 这样通过源IP地址、目的IP地址及目的端口就可以将IP 地址2与IP地址4间的呼叫划分为多个不同SIP中继群组上的呼叫,根据实际运用需要赋予其不同的呼叫源及相关的呼叫属性。 Thus by source IP address, destination IP address and destination port IP address can be the IP address of the call 2 4 divided into a plurality of calls on different SIP trunk group, given their different needs and according to the practical application of call origination call related attributes. 呼叫在每个业务模块上的负荷分担根据一定的负荷分担策略实现。 On each service call load sharing module sharing policy implemented according to a certain load. 以第一SIP实体为例,上行SIP消息到达服务端口后,可以根据一定的分担策略将其分发到业务模块的本地端口上,下行可以通过一定的分担策略选择一业务模块, 业务模块根据一定的策略选择一条SIPTG发送SIP消息。 In an example a first SIP entity, the SIP message arrival uplink service port, according to a certain strategy sharing distributed to the local port of the service module, the service module downlink may be selected by a certain sharing policy, according to a certain service module strategies SIPTG send a SIP message. 例如第一SIP实体的IP地址2 中的服务端口1接收到SIPTG-I上的SIP消息,底层根据一定的负荷分担策略(例如按呼叫平均分配或按照各业务模块的呼叫比例分配等)将该消息分发到业务模块1上处理,也可以将该消息从该服务端口1分发到其他业务模块上处理;同路呼叫中的后续消息处理路径保持与该呼叫的处理路径相同。 For example, the IP address of the first SIP entity in the service port 21 receives the SIP message on SIPTG-I, according to a certain bottom load sharing policy (e.g., an average or distribution according to a call according to the call distribution ratio of each of the service module, etc.) The the message distribution service module to the process 1, may also distribute the service message from the port 1 to the other business processing module; go the same way in subsequent call processing path message remains the same as the call processing path.

[0028] 2)根据源IP地址、目的IP地址、源端口和目的端口的组合作为判断条件进行划分SIP中继群组 [0028] 2) The source IP address, destination IP address, source port and destination port combination will be divided as a judgment condition SIP trunk group

[0029] 该方案与上述第一实施例方案类似,只是当接收方SIP实体接收到呼叫外的SIP 消息时会根据源IP地址、源端口、目的IP地址及目的端口作为判断条件,判断该消息来自哪条SIP中继群组,然后根据负荷分担策略将该消息分发到相应的业务模块上处理。 [0029] This scheme is similar to the first embodiment described embodiment, except when the recipient SIP entity receives a call outside the SIP message based on the source IP address, source port, destination IP address and destination port as a determination condition, determines that the message which from a SIP trunk group, then according to a load balancing policy to distribute the message to the corresponding service module.

[0030] 3)根据源IP地址、目的IP地址和源端口的组合作为判断条件进行划分SIP中继群组 [0030] 3) the source IP address, destination IP address and a combination of source port SIP trunk group is divided as a judgment condition

[0031] 该方案与上述第一实施例方案类似,只是当接收方SIP实体接收到呼叫外的SIP 消息时会根据源IP地址、源端口及目的IP地址作为判断条件,判断该消息来自哪条SIP中继群组,然后根据负荷分担策略将该消息分发到相应的业务模块上处理。 [0031] This scheme is similar to the first embodiment described embodiment, except when the recipient SIP entity receives a SIP call external message as a determination condition based on the source IP address, source port and destination IP address, the message is determined from which of SIP trunk group, in accordance with a load sharing policy and then distribute the message to the corresponding service processing module.

[0032] 以上所述,仅为本发明的较佳实施例而已,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。 [0032] The above are only preferred embodiments of the present invention, but not intended to limit the scope of the present invention, where any modifications within the spirit and principle of the present invention, equivalent substitutions, improvements, It should be included within the scope of the present invention.
