the processor circuitry is further configured to transmit one or more identities corresponding to the one or more message types and/or one or more priorities of the one or more identities to the user equipment.

10. A message receiving apparatus, comprising:

a transmitter configured to report auxiliary information comprising information on one or more message types preferred by a user equipment to a network device;

processor circuitry configured to descramble received control information by using an identity to which the message type corresponding to a service type corresponds; wherein a correspondence between the message type and the identity is preconfigured and different identities correspond to different message types; and

a receiver configured to receive data information corresponding to the control information under a condition that the control information is successfully descrambled.

11. The message receiving apparatus according to claim 10 , wherein when there are a plurality of identities, the processor circuitry descrambles the received control information according to priorities of the identities.

12. The message receiving apparatus according to claim 10 , wherein the auxiliary information further comprises one or more pieces of the following information: information on a type of the user equipment, information on one or more priorities of the one or more message types preferred by the user equipment, information on a position of the user equipment, information on a power state of the user equipment, and information on a power level of the user equipment.

13. The message receiving apparatus according to claim 12 , wherein the information on one or more message types preferred by the user equipment and/or the information on one or more priorities are/is reported when the user equipment accesses a network, or reported periodically, or reported when the information is changed;

the information on a type of the user equipment is reported when the user equipment accesses a network;

the information on a position of the user equipment is reported periodically, or when the user equipment enters another region from one region in a cell, or when a displacement distance of the user equipment reaches a preset threshold; and

the information on a power state and/or the information on a power level of the user equipment are/is reported periodically, or when the information is changed.

14. The message receiving apparatus according to claim 10 , wherein the receiver is further configured to receive one or more identities corresponding to one or more message types and/or one or more priorities of the one or more identities transmitted by the network device.

15. The message receiving apparatus according to claim 10 , wherein the processor circuitry is further configured to receive information on a reception level transmitted by the network device; and the information on a reception level is determined by the network device according to information on a power state and/or information on a power level in the auxiliary information.

16. The message receiving apparatus according to claim 10 , wherein the processor circuitry is further configured to determine a reception level of the user equipment according to a current power state and/or a current power level of the user equipment, or according to information on a reception level received from the network device;

and the processor circuitry is further configured to descramble the received control information by using one or more identities having priorities higher than or equal to that of the reception level.
