Abstract
A software upgrade method and system which relate to the field of communications technologies. The method is applied to an evolved core packet (EPC) system. The EPC system includes a system manager, a traffic decider, a first service server, and a second service server, and the first service server and the second service server are installed with service software of a first version. As a result, service continuity and stability of the EPC system are ensured.
Claims10
A method, applied to communication system, wherein the communication system comprises a system manager, a traffic decider, a first service server, and a second service server, and wherein the first service server and the second service server are installed with service software of a first version, the method comprising:
- controlling, by the system manager, the second service server to upgrade the installed service software from the first version to a second version, controlling the traffic decider to set a first service flow identifier comprised in a service data flow of a user equipment on the first service server to indicate the second service server, and controlling the first service server to transfer, to the second service server, the service data flow that comprises the first service flow identifier and that is on the first service server;
- receiving, by the traffic decider, a service data flow sent by the user equipment, and forwarding the service data flow to the second service server based on the first service flow identifier in the service data flow;
- and
- after the second service server becomes stable, controlling, by the system manager, the first service server to upgrade the installed service software from the first version to the second version.
A system, comprising:
- a first service server and a second service server;
- wherein the first and second service servers each comprise a wireless transceiver connected to a processor, and memory, wherein in the memory of the first service server and second service server contain a service software of a first version
- a traffic decider, comprising a transceiver, a memory and a processor, wherein the processor of the traffic decider is configured to execute the instructions stored on the memory of the traffic decider, and the memory of the traffic decider stores instructions for receiving a service data flow sent by a user equipment, and forward the service data flow, via the transceiver of the traffic controller to the second service server based on a first service flow identifier in the service data flow;
- a system manager, in electronic communication with the first service server and the second service server, and comprising a transceiver, a memory and a processor, wherein the processor of the system manager is configured to execute the instructions stored to the memory of the system manager the memory of the system manager stores instructions for controlling the second service server to upgrade the installed service software stored on the memory of the second service server from the first version to a second version, controlling the traffic decider to set the first service flow identifier comprised in a service data flow of the user equipment on the first service server to indicate the second service server, controlling the first service server to transfer, to the second service server, the service data flow that comprises the first service flow identifier and that is on the first service server, and controlling the first service server to upgrade the installed service software from the first version to the second version when the second service server becomes stable.
