Abstract
An information transmission method includes: receiving, by a network element selector from a user equipment (UE), a first message including identification information of the UE; determining, based on the identification information of the UE, a user group to which the UE belongs; determining a controller corresponding to the user group; and receiving and sending a further message to the controller.
Claims20
An information transmission method, comprising:
- receiving, by a network element selector, a first message from a user equipment (UE), wherein the first message comprises identification information of the UE, wherein the identification information of the UE indicates that the UE belongs to a first user group;
- determining, by the network element selector based on a correspondence between user groups of UEs and controllers, a first controller corresponding to the first user group, wherein, in the correspondence, each of the controllers corresponds to at least one user group;
- sending, by the network element selector, the first message to the first controller;
- receiving, by the first controller, the first message;
- obtaining, by the network element selector, information of a second controller;
- receiving, by the network element selector, a second message, wherein the second message comprises a user group list including at least one user group migrated from the first controller to the second controller;
- updating, by the network element selector, the correspondence by
- adding, in the correspondence, the user group list migrated to the second controller to a user group corresponding to the second controller, and
- deleting, in the correspondence, the user group list migrated to the second controller from a user group corresponding to the first controller;
- receiving, by the network element selector, a third message from the UE;
- determining, by the network element selector based on the updated correspondence, the second controller;
- sending, by the network element selector, the third message to the second controller;
- and
- receiving, by the second controller, the third message.
