Accordingly, the embodiments herein disclose a method for access prioritization in a Mission Critical Push to Talk (MCPTT) network. A dispatcher detects an occurrence of an emergency in a location of a Mission Critical Services (MCX) zone. The dispatcher detects presence of at least one first responder device for the emergency in close proximity from the location of the emergency. The dispatcher determines distance of the at least one first responder device from the location of the detected emergency. The dispatcher prioritizes in the emergency location, an access to the MCPTT network for at least one User Equipment (UE) device other than the at least one first responder device, if the at least one first responder device is at a distance more than a pre-determined distance from the location of the detected emergency.

Accordingly, an embodiment provides a method for access prioritization by a device in a mission critical push to talk (MCPTT) network that includes detecting an occurrence of an emergency in a location of a mission critical service (MCX) group; identifying a distance of each of one or more devices from the location of the detected emergency; and prioritizing in the location of the detected emergency, an access to the MCPTT network for at least one first device among the one or more devices based on the identified distance, with the at least one first device including at least one user equipment (UE).
