Abstract

The invention discloses a parameter adjustment method and device for multimedia communication, and a mobile terminal. The method comprises the steps of when a first mobile terminal and a second mobileterminal perform multimedia communication, detecting whether a multimedia parameter used in the current multimedia communication needs adjusting; if it is detected that the multimedia parameter needsadjusting, generating a negotiation request of the multimedia parameter, and sending the negotiation request to the second mobile terminal; and when an acknowledgement message sent by the second mobile terminal in response to the negotiation request is received, adjusting the multimedia parameter used in the multimedia communication according to the acknowledgement message. Through adoption of the parameter adjustment method, multimedia communication quality is guaranteed.

Description

technical field [0001] The present application relates to the technical field of storage, in particular to a parameter adjustment method, device and mobile terminal of multimedia communication. Background technique [0002] Video communication refers to communication services that deliver video information. During video communication, the communication parties need to first negotiate the multimedia parameters used in the video communication process. In the current LTE trunking dispatching system, the communication parties complete the negotiation of multimedia parameters during the video call, and will not change the multimedia parameters in subsequent calls. [0003] However, in a Long Term Evolution (English: Long Term Evolution, LTE for short) clustered private network scenario, when a user performs a call service, he is generally on the move, and the air interface environment where he is located is constantly changing. If the user is performing real-time video services...
