Short packet data service

摘要

A novel message exchange protocol is disclosed. In one example, a method of transmitting data includes generating, with a wireless device, an application data message for an application; evaluating one or more criteria for determining whether to send the application data message via a data radio bearer (DRB) channel or via a signaling radio bearer (SRB) channel that communicatively couples the wireless device to a network resource; and based on determining to send the application data message via the SRB channel, sending the application data message to the network resource via the SRB channel.

1. A method of transmitting data, the method comprising:
generating, with a wireless device, a first application data message for a first application; evaluating one or more criteria for determining whether to send the first application data message via a data radio bearer (DRB) channel or via a signaling radio bearer (SRB) channel that communicatively couples the wireless device to a network resource; based on determining to send the first application data message via the SRB channel, sending the first application data message to the network resource via the SRB channel, wherein the first application message has a data size that is less than a data size threshold; generating, with the wireless device, a second application data message for a second application; determining that a data size of the second application data message is greater than the data size threshold; sending signaling data via the SRB channel to the network resource to establish the DRB channel between the wireless device and the network resource; and sending the second application data message via the DRB channel.
