Clive Carter was back in the dock yesterday for a preliminary hearing at the High Court in Glasgow.
Carter is accused of attacking Khanokporn Satjawat in the female toilets at the city's SECC complex on November 12 last year.
The 35-year-old entered a guilty plea to the reduced charge of culpable homicide on the grounds of diminished responsibility at a previous calling of the case in June.
But the plea is unacceptable to prosecutors and Judge Lord Pentland set a murder trial due to begin next month.
Mrs Satjawat, 42, died while attending a conference for HIV drug therapy at the venue known as the Armadillo.
Carter, of Motherwell, is believed to have been working as a security guard at the time.
Prosecutors allege Carter repeatedly struck Mrs Satjawat on the head and body with a fire extinguisher.
He faces a further charge that he attempted to defeat the ends of justice.
It is claimed he cleaned blood and hair from the alleged murder weapon in a glass-washing room at the venue.
Carter is also said to have hidden a blazer he was wearing in a nearby Portacabin.
He is then alleged to have told a number of people - including police - that he had seen a male carrying a fire extinguisher and taken it from him.
Carter is also charged with committing a breach of the peace by leaving a woman in "fear and alarm" at the Holiday Inn Express in the city's Stockwell Street on November 4.
It is alleged that knowing she was alone, Carter claimed to be attending to a fire in her room despite knowing there was no blaze.
