Method and system for providing priority communication in a mission-critical push-to-talk (MCPTT) service

A mission critical push-to-talk (MCPTT) server in a wireless communication system, the MCPTT server comparing:

• a processor;
• and
• a memory communicatively coupled to the processor, wherein the memory stores processor executable instructions which on execution causes the processor to:
• receive, from a first user equipment (UE), a request for a connection to communicate with one or more second UEs, wherein the request includes at least a first priority score associated with a type of the connection;
• determine, based on the request, a second priority score corresponding to the first UE, wherein the second priority score is associated with type information;
• retain the first priority score in case that the first priority score is greater than the second priority score;
• modify the first priority score to the second priority score in case that the first priority score is less than the second priority score;
• identify a third priority score associated with a pre-existing connection, wherein the third priority score is associated with a type of the pre-existing connection;
• and
• perform, based on the retained or modified first priority score and the second priority score, one of:
• approving the request for the connection in case that the retained or modified first priority score is greater than the third priority score, or
• rejecting the request for the connection in case that the retained or modified first priority score is less than the third priority score.
