Abstract

A method for establishing a virtual base station includes: receiving a message of poor network coverage sent by an operator server, where the message includes information of a location where network coverage is poor and information of a second mode; acquiring, according to the information of the location and the information of the second mode, a multimode terminal capable of being compatible with the second mode; returning an identification of the multimode terminal to the operator server; receiving a virtual base station establishment request message sent by the operator server; forwarding, according to the identification of the multimode terminal, the virtual base station establishment request message to the multimode terminal; and forwarding a virtual base station successfully-established message to the operator server.

First claim

What is claimed is:

1. A method for establishing a virtual base station, comprising:
receiving, by a wireless network controller, a notification message of poor network coverage sent by an operator server, wherein the notification message of the poor network coverage is sent by the operator server when a network coverage level in a network of a second mode is detected to be lower than a preset network coverage threshold, and comprises information of a location where the network coverage level of the second mode is lower than the network coverage threshold and information of the second mode, wherein the second mode is a second cellular network mode;
acquiring, by the wireless network controller, according to the information of the location and the information of the second mode, a multimode terminal capable of being compatible with the second mode;
returning, by the wireless network controller, an identification of the multimode terminal to the operator server;
receiving, by the wireless network controller, a virtual base station establishment request message sent by the operator server, wherein the virtual base station establishment request message comprises the identification of the multimode terminal and the information of the second mode;
forwarding, by the wireless network controller, according to the identification of the multimode terminal, the virtual base station establishment request message to the multimode terminal to enable the multimode terminal to generate a virtual machine and load a virtual base station mirror that is the same as the second mode to establish a virtual base station, wherein after the virtual base station is established successfully, the multimode terminal becomes a base station of at least one of terminals of the second mode and operates in the first mode to provide a data transmission path between a core network of the first mode and a core network of the second mode;
receiving, by the wireless network controller, a virtual base station successfully-established message sent by the multimode terminal, wherein the virtual base station successfully-established message comprises an identification of the virtual base station; and
forwarding, by the wireless network controller, the virtual base station successfully-established message to the operator server.

2. The method according to claim 1 , wherein, the forwarding the virtual base station establishment request message to the multimode terminal comprises:
sending, by the wireless network controller, the virtual base station establishment request message to a radio access network (RAN), and forwarding, by the RAN, the virtual base station establishment request message to the multimode terminal.

3. The method according to claim 1 , wherein the receiving a virtual base station successfully-established message sent by the multimode terminal comprises:
receiving, by the wireless network controller, the virtual base station successfully-established message sent by the multimode terminal and forwarded by the RAN.

4. The method according to claim 1 , wherein after the receiving a virtual base station successfully-established message sent by the multimode terminal, further comprising:
establishing, by the wireless network controller, a corresponding relation between the identification of the multimode terminal and the identification of the virtual base station.

5. The method according to claim 4 , further comprising:
receiving, by the wireless network controller, a virtual base station destruction request message sent by the operator server, wherein the virtual base station destruction request message comprises the identification of the virtual base station;
sending, by the wireless network controller, a data transmission path release message to a core network of the multimode terminal to release the data transmission path to a core network of the second mode;
receiving, by the wireless network controller, a successfully-released message returned by the core network of the multimode terminal;
determining, by the wireless network controller, the multimode terminal according to the identification of the virtual base station and the corresponding relation between the identification of the multimode terminal and the virtual base station;
sending, by the wireless network controller, a virtual base station deletion request message to the RAN to enable the RAN to forward the virtual base station deletion request message to the multimode terminal, wherein the virtual base station deletion request message comprises the identification of the virtual base station;
receiving, by the wireless network controller, a virtual base station successfully-deleted message sent by the multimode terminal and forwarded by the RAN, wherein the virtual base station successfully-deleted message is sent by the multimode terminal after a virtual base station mirror corresponding to the identification of the virtual base station is unloaded and the virtual machine is deleted;
deleting, by the wireless network controller, the corresponding relation between the identification of the multimode terminal and the identification of the virtual base station; and
forwarding, by the wireless network controller, the virtual base station successfully-deleted message to the operator server.

6. The method according to claim 1 , wherein the multimode terminal operates in a WIFI mode or a first cellular network mode.

7. A wireless network controller, comprising:
a second receiving unit, configured to receive a notification message of poor network coverage sent by an operator server, wherein the notification message of the poor network coverage is sent by the operator server when a network coverage level in a network of a second mode is detected to be lower than a preset network coverage threshold, and comprises information of a location where the network coverage level of the second mode is lower than the network coverage threshold and information of the second mode, wherein the second mode is a second cellular network mode;
a multimode terminal acquiring unit, configured to acquire, according to the information of the location and the information of the second mode, a multimode terminal capable of being compatible with the second mode;
a second sending unit, configured to return an identification of the multimode terminal to the operator server;
wherein the second receiving unit is further configured to receive a virtual base station establishment request message sent by the operator server, wherein the virtual base station establishment request message comprises the identification of the multimode terminal and the information of the second mode;
the second sending unit is further configured to forward, according to the identification of the multimode terminal, the virtual base station establishment request message to the multimode terminal, to enable the multimode terminal to generate a virtual machine and load a virtual base station mirror that is the same as the second mode to establish a virtual base station, wherein after the virtual base station is established successfully, the multimode terminal becomes a base station of at least one of terminals of the second mode and operates in the first mode to provide a data transmission path between a core network of the first mode and a core network of the second mode;
the second receiving unit is further configured to receive a virtual base station successfully-established message sent by the multimode terminal, wherein the virtual base station successfully-established message comprises an identification of the virtual base station; and
the second sending unit is further configured to forward the virtual base station successfully-established message to the operator server.
