Abstract

A method for solving the co-existence problem, a base station, user equipment, and system for performing the method. The method includes: pre-configuring the information for co-existence working mode by a base station of a first communication system for a user equipment, receiving, by the base station of the first communication system from the user equipment in the first communication system, a mode establishing request for indicating the co-existence problem experienced by the user equipment and providing the assistance information for co-existence working mode in which the user equipment performs a first communication with the base station and performs a second communication with an apparatus in a second communication system which is different from the first communication system.

First claim

What is claimed is:

1. A method for solving a co-existence problem, comprising:
pre-configuring information for co-existence working mode by a base station of a first communication system for a user equipment,
receiving, by the base station of the first communication system from the user equipment in the first communication system, a mode establishing request for indicating the co-existence problem experienced by the user equipment and providing assistance information for co-existence working mode in which the user equipment performs a first communication with the base station and performs a second communication with an apparatus in a second communication system which is different from the first communication system,
encapsulating, by the base station, configuration information of a co-existence working mode allowed to be utilized by the user equipment into an establishing response message, and transmitting the establishing response message to the user equipment; and
receiving, by the base station, a message indicating whether configuration of the co-existence working mode has been completed fed back from the user equipment,
wherein the pre-configured information of the co-existence working mode indicates whether the user equipment can deny uplink transmission of the first communication system.

2. The method of claim 1 , further comprising:
judging, by the base station, whether to allow the user equipment to enter the co-existence working mode according to operation condition of the first communication system, and if no, encapsulating information indicating to reject the user equipment to enter the co-existence working mode into the establishing response message.

3. The method of claim 1 , further comprising:
selecting, by the base station, the co-existence working mode allowed to be utilized by the user equipment according to operation condition of the first communication system.

4. The method of claim 3 , wherein the mode establishing request comprises information indicating a co-existence working mode selected by the user equipment, and the method further comprises:
judging, by the base station, whether to allow the user equipment to utilize the co-existence working mode selected by the user equipment according to the operation condition of the first communication system, and if yes, encapsulating into the establishing response message information indicating the co-existence working mode selected by the user equipment is allowed to be utilized.

5. A method for solving a co-existence problem, comprising:
receiving, by a user equipment of a first communication system from a base station in the first communication system, pre-configured information for co-existence working mode,
transmitting, by the user equipment of the first communication system to the base station in the first communication system, a mode establishing request for indicating the co-existence problem experienced by the user equipment and providing assistance information for co-existence working mode in which the user equipment performs a first communication with the base station and performs a second communication with an apparatus in a second communication system which is different from the first communication system,
receiving, by the user equipment from the base station, an establishing response message comprising configuration information of a co-existence working mode allowed to be utilized by the user equipment;
configuring the co-existence working mode according to the configuration information; and
feeding back, by the user equipment to the base station, a message indicating whether configuration of the co-existence working mode has been completed,
wherein the pre-configured information of the co-existence working mode indicates whether the user equipment can deny uplink transmission of the first communication system.

6. The method of claim 5 , further comprising:
judging, by the user equipment, whether the base station allows the user equipment to enter the co-existence working mode according to the establishing response message.

7. The method of claim 5 , further comprising:
selecting, by the user equipment, a co-existence working mode according to the second communication system; and
encapsulating information of the selected co-existence working mode into the mode establishing request.

8. The method of claim 5 , further comprising:
encapsulating, by the user equipment, information indicating a type and/or service of the second communication system into the mode establishing request.

9. A base station, configured in a first communication system, comprising:
a control device, configured to pre-configure information for co-existence working mode;
a receiving device, configured to receive, from a user equipment in the first communication system, a mode establishing request for indicating a co-existence problem experienced by the user equipment and providing assistance information for co-existence working mode in which the user equipment performs a first communication with the base station and performs a second communication with an apparatus in a second communication system which is different from the first communication system,
a control device, configured to encapsulate configuration information of a co-existence working mode allowed to be utilized by the user equipment into an establishing response message; and
a transmitting device, configured to transmit the pre-configured information for co-existence working mode and the establishing response message to the user equipment,
wherein the receiving device is further configured to receive a message indicating whether configuration of the co-existence working mode has been completed fed back from the user equipment, and
wherein the pre-configured information of the co-existence working mode indicates whether the user equipment can deny uplink transmission of the first communication system.

10. The base station of claim 9 , wherein the control device is further configured to:
judge whether to allow the user equipment to enter the co-existence working mode according to operation condition of the first communication system, and if no, encapsulate information indicating to reject the user equipment to enter the co-existence working mode into the establishing response message.

11. The base station of claim 9 , wherein:
the receiving device is further configured to receive, from the user equipment, a reconfiguration request for requesting to re-configure the co-existence working mode,
the control device is further configured to encapsulate reconfiguration information for re-configuring the co-existence working mode into a reconfiguration response message, and
the transmitting device is further configured to transmit the reconfiguration response message to the user equipment.

12. The base station of claim 9 , wherein:
the control device is further configured to encapsulate reconfiguration information for re-configuring the co-existence working mode into a reconfiguration command instructing the user equipment to re-configure the co-existence working mode,
the transmitting device is further configured to transmit to the user equipment the reconfiguration command, and
the receiving device is further configured to receive a reply signal indicating whether reconfiguration of the co-existence working mode has been completed fed back from the user equipment.

13. A user equipment configured in a first communication system, comprising:
a receiving device, configured to receive pre-configured information for co-existence working mode from a base station in the first communication system;
an information pro
