Detailed Description
For the purpose of making the objects, technical means and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of an application scenario of the call processing method in the present application. As shown in fig. 1, an MDC links multiple gateway interface devices (e.g., PSTN/PLMN/SDK-GW/SIP Server, etc.) that can be outgoing, and when an outgoing call or an outgoing call is received, the MDC needs to determine which gateway is outgoing. Fig. 2 is a basic flowchart of a call processing method according to the present application. As shown in fig. 2, the MDC may automatically select the outgoing gateways to ensure load balancing among the outgoing gateways as much as possible. The method specifically comprises the following steps:
When the MDC selects the gateway, the available outgoing gateway is filtered out, and then the appropriate gateway interface equipment is selected as the outgoing gateway according to the current load through the following steps.
At step 202, the traffic capability M and the current number of connections N of the optional gateway interface devices are determined.
In the prior art, a heartbeat mechanism is adopted for reporting the traffic capacity of the gateway, in the application, for the gateway interface equipment with the traffic capacity reporting capacity, a polling reporting mechanism is adopted for the traffic capacity, the reported traffic capacity value is taken as M, and when the reported traffic capacity value changes, the M is updated accordingly.
In addition, for a gateway interface device without the capability of reporting traffic, M is the maximum access number of the device, and specifically may be the historical maximum value of the current connection number (that is, the maximum value of N mentioned later), and the value is a dynamic value in the initial process, and is fixed after the maximum value is reached.
For the acquisition of the current connection number N, the default N is 0, the incoming call or the outgoing call is successful, the N is added with 1, the incoming call or the outgoing call is identified, and the N is unchanged; after the incoming call or the outgoing call is successful, the connection is established, and when the connection is removed, N is reduced by 1.
Specifically, the current load may be directly set as the ratio of the current connection number to the traffic capacity, or may be the product of the ratio of the current connection number to the traffic capacity and a weight (e.g., 100), so that the current load may be converted into an integer.
And step 204, selecting one gateway interface device from the gateway interface devices as an outgoing gateway of the private network terminal according to the current load.
When the outgoing gateway is selected, the priority can be determined according to the current load, and then one outgoing gateway is selected according to the sequence of the priority from high to low.
When determining the priority, the states of the gateway interface devices may be classified into 4 types:
A. gateways with less than full load, i.e., gateways with N < M;
B. the gateway with the full traffic reporting capacity, namely the gateway with the traffic reporting capacity, wherein N is M;
C. the gateway which is not reported with full traffic capacity load, namely the gateway which does not have traffic capacity reporting and has N (M);
D. set as the gateway that is punished.
Wherein, for the gateway interface device without traffic reporting capability, preferably adopting heuristic attempt:
when a call fails (for example, the gateway does not respond to timeout or replies 3456XX), the gateway interface device is punished to reduce the priority, and the gateway is set as a 'punished gateway'; after the subsequent call or incoming call is successful, the 'punished gateway' is cancelled, and the N/M of the gateway is set to be 1, namely N is equal to M.
For the gateway interface device in the above four states, the priority is from high to low: a > C > D > B.
For a plurality of gateway interface devices in the same type A, the lower the current load is, the higher the priority is; for a plurality of gateway interface devices in the same type B, the sequence number sequence of the gateway nodes can be used as priority sequencing, or one can be randomly selected as an outgoing gateway; for a plurality of gateway interface devices in the same type C, the sequence number sequence of the gateway nodes can be used as priority sequence, or one can be randomly selected as an outgoing gateway; for a plurality of gateway interface devices in class D, the sequence numbers of the gateway nodes may be arranged in order as a priority ranking, or one of the gateway nodes may be randomly selected as an outgoing gateway.
And step 205, processing the call request by using the selected outgoing gateway, and establishing communication connection between the public network terminal and the private network terminal.
The call processing method in the present application is terminated.
By the call processing method, in an application scenario that one MDC is connected with a plurality of outgoing gateways (including PSTN/PLMN/SDK-GW/SIP Server), when outgoing calls are made, the load condition of each gateway which is configured in the MDC system and allows outgoing can be calculated, the MDC can automatically select which gateway is used for outgoing according to the load, and the lighter the load is, the better the load can be selected. By using the method, the MDC can go out to the public network mobile phone through different gateways, and the loads of the different gateways are uniformly distributed to a certain extent, so that the system performance is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
