Abstract
Embodiments of this application provide an information transmission method, a network element selector, and a controller. The information transmission method provided in the embodiments of this application includes: receiving, by an NES from an external network element, a first message including identification information of 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 then sending the first message to the controller.
Claims11
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;
- determining, by the network element selector based on the identification information of the UE, a first user group to which the UE belongs;
- 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 network element selector, a second message, wherein the second message comprises an identifier of a second controller and 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;
- and
- sending, by the network element selector, the third message to the second controller.
9 more elements
A network element selector, comprising a receiver, a processor, and a transmitter, wherein
- the receiver is connected to the processor, and the processor is further connected to the transmitter,
- the receiver is configured to receive a first message from a user equipment (UE), wherein the first message comprises identification information of the UE,
- the processor is configured to:
- determine, based on the identification information of the UE, a first user group to which the UE belongs, and
