Method of prioritizing random access for multimedia priority and mission critical services and apparatus thereof

A method of random access, the method comprising:

• receiving, from a base station, at least one of a first set of random access prioritization parameters, a second set of random access prioritization parameters, and a third set of random access prioritization parameters;
• identifying whether a random access procedure is initiated for handover;
• identifying whether the third set of random access prioritization parameters is received from the base station in case that the random access procedure is initiated for handover;
• identifying whether the first set of random access prioritization parameters is received from the base station in case that the third set of random access prioritization parameters is not received from the base station;
• and
• applying the first set of random access prioritization parameters during the random access procedure in case that the first set of random access prioritization parameters is received from the base station.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station via the transceiver, at least one of a first set of random access prioritization parameters, a second set of random access prioritization parameters, and a third set of random access prioritization parameters,
• identify whether a random access procedure is initiated for beam failure recovery,
• identify whether the second set of random access prioritization parameters is received from the base station in case that the random access procedure is initiated for beam failure recovery,
• identify whether the first set of random access prioritization parameters is received from the base station in case that the second set of random access prioritization parameters is not received from the base station, and
• apply the first set of random access prioritization parameters during the random access procedure in case that the first set of random access prioritization parameters is received from the base station.
