1. A method for providing streaming service assistance performed by a modem processor of a wireless device, comprising:
receiving, from another processor of the wireless device over an attention (AT) interface, an attention (AT) command that is a bitrate recommendation action command for a streaming service, the bitrate recommendation action command including at least an indication of a first stream identifier, an indication of a requested bitrate, and an indication of a direction;
determining a second stream identifier and a logical channel identifier (LCID) associated with the first indication of the stream identifier in response to receiving the AT command that is a bitrate recommendation action command from the other processor of the wireless device;
sending a network assistance request to a base station of a radio access network (RAN) including the second stream identifier and LCID;
receiving a network assistance response from the base station of the RAN including the second stream identifier and LCID;
determining a bitrate recommendation in response to receiving the network assistance response from the base station of the RAN; and
sending a response that is a bitrate recommendation response to the other processor of the wireless device over the AT interface, the bitrate recommendation response including at least the indication of the first stream identifier, an indication of the bitrate recommendation, and the indication of the direction.
