In the method a procedure for setting up a communication link between a first user equipment and a second user equipment via a communications network is initiated. Information regarding at least two modes of communication that can be used for communication via the communication link is signalled between the first and second user equipment. An indicator regarding a mode to be used for the communication is also signalled between the first user equipment and the second user equipment. After the signalling steps, a procedure for setting the mode of communication in accordance with the indicator is initiated in at least in one of the user equipment. According to an alternative embodiment signalling for reserving a possibility for at least tow different communication modes occurs between elements of the communication system. ## Claims ### Claim 1 A method, comprising: initiating, by a first user equipment, of a procedure for setting up a communication link between the first user equipment and a second user equipment via a communications network; signaling, from the first user equipment during the procedure for setting up the communication link, a call setup message to the second user equipment indicating two modes of communication that can be used for a communication via the communication link, the two modes of communication comprising a speech mode and a multimedia mode; beginning the communication via the communication link with the second user equipment using one of the speech mode and the multimedia mode and reserving the other of the speech mode and the multimedia mode for possible use during the communication; and signaling, from the first user equipment during communication with the second user equipment, an indicator to the second user equipment regarding changing a mode used for the communication to the other of the speech mode and the multimedia modes for the communication, wherein the signaling is user-to-user signaling during an active phase of the communication. ### Claim 2 (depends on 1) The method of claim 1 further comprising: initiating in the first user equipment a procedure for changing the mode during the communication in accordance with the indicator, wherein the first user equipment communicates with the communications network via a wireless interface. ### Claim 3 (depends on 2) The method of claim 2, wherein the text message is “swap to speech. ### Claim 4 (depends on 1) The method of claim 1, wherein the indicator is a text message. ### Claim 5 (depends on 1) The method of claim 1, wherein the indicator is a command. ### Claim 6 (depends on 1) The method of claim 1, wherein the indicator is a flag. ### Claim 7 An apparatus comprising a first user equipment, comprising: a processor; and a memory storing computer program code, the memory and the computer program code configured, with the processor, to cause the first user equipment to: initiate a procedure for setting up a communication link between the first user equipment and a second user equipment via a communications network; signal from the first user equipment to the second user equipment, during the procedure for setting up the communication link, information regarding two modes of communication that can be used for a communication via the communication link, the two modes of communication comprising a speech mode and a multimedia mode; beginning the communication via the communication link with the second user equipment using one of the speech mode and the multimedia mode and reserving the other of the speech mode and the multimedia mode for possible use during the communication; and signal from the first user equipment to the second user equipment an indicator regarding changing a mode used for the communication to the other of the speech mode and the multimedia modes for the communication, wherein the signal is user-to-user signaling during an active phase of the communication. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the first user equipment is further caused to: change the mode during the communication in accordance with the indicator, wherein the first user equipment communicates with the communications network via a wireless interface. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the indicator is a text message.
