6. The apparatus of claim 5, wherein the apparatus further comprises:
the first re-authorization request construction unit is used for constructing a first re-authorization request for the AVP according to the attribute value pair of the strategy to be installed;
a first re-authorization request sending unit, configured to send the first re-authorization request to a packet data network gateway PGW, so that the packet data network gateway PGW triggers a reverse proprietary bearer creation procedure when detecting that no proprietary bearer corresponding to the policy to be installed exists;
and the first re-authorization response receiving unit is used for receiving a first re-authorization response message fed back by the packet data network gateway PGW.
7. The apparatus of claim 5, wherein the apparatus further comprises:
the deletion strategy receiving unit is used for receiving a session termination request initiated by a critical task server MCS, wherein the session termination request carries an attribute value pair AVP of a strategy to be deleted;
the deletion strategy analysis unit is used for analyzing the session termination request to obtain an attribute value pair AVP of the strategy to be deleted;
and the second response feedback unit is used for feeding back a session termination response message to the mission critical server MCS.
8. A communication system, comprising: the system comprises a critical task server MCS, a policy and charging rule function unit PCRF, a policy and charging execution function unit PCEF and a service policy providing point function unit AF;
the critical task server MCS is configured to initiate an authentication and authorization request to the policy and charging rule function unit PCRF under the condition that the target user quality of service QoS is known, where the authentication and authorization request carries an attribute value pair AVP of a policy to be installed corresponding to the target user quality of service QoS;
the policy and charging rules function PCRF for executing the policy derivation method of a policy charging control PCC system according to any of claims 1 to 4.
9. A communication device comprising a memory and a processor:
the memory is used for storing program instructions;
the processor is configured to execute the policy derivation method for policy charging control PCC system according to any one of claims 1 to 4 according to a program stored in the memory.
10. A storage medium having stored thereon a computer program, which when executed by a processor implements a policy derivation method of a policy charging control, PCC, system according to any one of claims 1 to 4.
