Maintaining communication channel for device notifications

摘要

A first communication channel is established between a user device and a server using a cellular network. The user device receives a timeout interval for the first communication channel. The user device transmits a packet to maintain the first communication channel when the user device detects that other data is being transmitted using a second communication channel during the timeout interval.

主权项

1. A method comprising:
establishing a first communication channel between a client device and a notification server, wherein the first communication channel uses a cellular network; establishing a second communication channel between the client device and a content server, wherein the second communication channel uses the cellular network; identifying a cellular network service provider; transmitting data indicative of the cellular network service provider to the notification server; receiving information indicative of a timeout interval from the notification server via the first communication channel, wherein the timeout interval is based on the cellular network service provider and is indicative of a time period before one or more of the client device or the cellular network service provider closes the first communication channel; setting a timer for the first communication channel based on the timeout interval; before an expiration of the timer, detecting that data is being transferred via the second communication channel; and upon detecting that data is being transferred via the second communication channel, transmitting a packet to the notification server via the first communication channel to prevent the first communication channel from being closed.
