When a mobile user requests a priority service, the network does not prioritize the service and according to the priority level of the mobile user, it provides a higher priority than the ordinary service. In the case of network congestion or insufficient resources, priority services sent by mobile users with high priority service levels can be processed with high priority to meet the needs of high priority mobile users.
  • the implementation scheme of the voice priority service supported by the 3GPP network is as follows.
  • the voice priority service in the 3GPP network is a subscription service and does not require mobile users to actively perform registration, logout, and other operations. Which mobile users are allowed to use priority services and setting the priority service level settings for mobile users is determined by the operator or other agencies.
  • the access level of ordinary mobile users defined by 3GPP is divided into 10 levels from 0 to 9, and 11 to 15 are 5 special access levels, which are defined as mobile network use, security services, public agency personnel, and internal employees of operators.
