A mobility management method in a communication network, wherein the communication network is configured to enable communication in accordance with at least a first network standard and a second network standard, wherein the communication network comprises at least first network devices (13, 14) and second network devices (16, 17, 21) corresponding to each network standard, each of the first network devices (13, 14) being configured for data communication with the corresponding second network devices (16, 17, 21) in the corresponding network standard, the second network devices (16, 17, 21) in each network standard being configured to be communicatively coupled to at least one user equipment, UE; the method comprising: providing a single radio controller, SRC, the SRC being a third network device communicatively coupled to at least the second network devices (16, 17, 21) corresponding to at least the first and the second network standards and configured to manage at least the second network devices (16, 17, 21), and receiving, by the SRC, one or more paging messages for the at least one UE sent by at least one first network device (13, 14), wherein each of the one or more paging messages carries a user identifier used for indicating the at least one UE; characterised in that the method further comprises: determining, by the SRC, a paging management context of the at least one UE according to the user identifier in the one or more paging messages, wherein the paging management context of the at least one UE records network standard information, and the network standard information is used for indicating a network standard on which the at least one UE camps when switching to an idle state or a network standard to which the at least one UE is redirected after switching to an idle state; and determining, by the SRC, a paging range according to the paging management context of the at least one UE and at least one of the paging messages, and initiating paging on the at least one UE in a cell in the paging range based on a comparison between the paging management context of the at least one UE and the at least one of the paging messages. providing a single radio controller, SRC, the SRC being a third network device communicatively coupled to at least the second network devices (16, 17, 21) corresponding to at least the first and the second network standards and configured to manage at least the second network devices (16, 17, 21), and receiving, by the SRC, one or more paging messages for the at least one UE sent by at least one first network device (13, 14), wherein each of the one or more paging messages carries a user identifier used for indicating the at least one UE; characterised in that the method further comprises: determining, by the SRC, a paging management context of the at least one UE according to the user identifier in the one or more paging messages, wherein the paging management context of the at least one UE records network standard information, and the network standard information is used for indicating a network standard on which the at least one UE camps when switching to an idle state or a network standard to which the at least one UE is redirected after switching to an idle state; and determining, by the SRC, a paging range according to the paging management context of the at least one UE and at least one of the paging messages, and initiating paging on the at least one UE in a cell in the paging range based on a comparison between the paging management context of the at least one UE and the at least one of the paging messages. determining, by the SRC, a paging management context of the at least one UE according to the user identifier in the one or more paging messages, wherein the paging management context of the at least one UE records network standard information, and the network standard information is used for indicating a network standard on which the at least one UE camps when switching to an idle state or a network standard to which the at least one UE is redirected after switching to an idle state; and determining, by the SRC, a paging range according to the paging management context of the at least one UE and at least one of the paging messages, and initiating paging on the at least one UE in a cell in the paging range based on a comparison between the paging management context of the at least one UE and the at least one of the paging messages.
