With tightening restrictions over the push limit and frequency of vendor channels, the push reach rate and delivery speed are also affected. For specific restrictions, please see:

• Vendor Channel Limit Description
• Vendor Channel QPS Limit Description

TPNS provides two channel assignment policies: smart assignment and custom. These policies will improve the overall push reach rate and delivery speed against the restrictions of the vendor channels.

Channel Overview

Channel Policy Overview

Smart assignment

TPNS will take into account the device status, segment active status, and push channel status to intelligently assign the optimal delivery channel for each device to achieve the following effects:

1. Improve the overall push reach rate.
2. Speed up the overall message arrival.
3. Save the resources of the vendor channels.

Custom channel policy

Currently, the Mi, OPPO, and vivo channels limit the daily number of pushes. You can choose the channels through which this push can be delivered according to business needs and personalize the push channel delivery policy to save vendor channel resources and maximize the value of pushes.
The table below specifies the delivery rules of a custom policy.

Getting Started

Console

When creating a push in the console, you can select a channel policy for it in the following path:
TPNS Console -> Push Management -> Create Push -> Advanced Settings -> Channel Policy

Smart assignment

Select Smart assignment. The system will intelligently assign the delivery channel for each device. For more information, please see the rules of smart assignment.

Custom policy for Android channels

Select Custom. You can click View Details to see the vendor quota details.

You can choose the channel used for push according to the remaining quota of the current vendor channels and the priority of the push task. For more information, please see the rules of the custom policy. We recommend selecting It is preferentially delivered through TPNS channel when the device is online to save vendor channel resources.

Note：

The TPNS channel cannot be disabled.

Custom policy for iOS channels

You can choose the channel used for push based on the priority of the push task. For more information, please see the rules of the custom policy. We recommend selecting It is preferentially delivered through TPNS channel when the device is online to ensure the fastest notification delivery to the device.

RESTful API

Set the optional channel_rules parameter for the RESTful API. For more information, please see channel_rules parameter description in the Push API documentation.
