and the paging type corresponding to the paging message is determined by the UE in accordance with the indication information. ### Claim 6 (depends on 1) The paging method according to claim 1, wherein a predetermined parameter expressed in a predetermined expression mode is carried in the paging message, and different expression modes of the predetermined parameter correspond to different paging types; and the paging type corresponding to the expression mode of the predetermined parameter in the paging message is determined by the UE, to acquire the paging type corresponding to the paging message. ### Claim 7 (depends on 1) The paging method according to claim 1, wherein a first predetermined parameter is carried or not carried in the paging message, and it is determined whether the first predetermined parameter is carried in the paging message in accordance with the paging type; and the paging type corresponding to the paging message is determined by the UE in accordance with whether the first predetermined parameter is carried in the paging message. ### Claim 8 A paging method, comprising: determining, by a base station, a paging type of a paging for a UE upon the base station initiates the paging for the UE, the paging type comprising an access network paging initiated by an access network or a core network paging initiated by a core network; and transmitting, by the base station, a paging message for determining the paging type to the UE. ### Claim 9 (depends on 8) The paging method according to claim 8, wherein indication information of the paging type is carried in the paging message;
