In order to improve usage factor of system resource; And user's quality of server; The embodiment of the invention provides a kind of method, system and device of launching and closing of CoMP transmission mode, in this method, when the QoS of business on a certain direction of user terminal can't guarantee; According to the reason that causes QoS to guarantee, launch the CoMP transmission.Because whether the QoS according to the business of user terminal can guarantee in embodiments of the present invention, launches the CoMP transmission mode, therefore can effectively improve quality of services for users, and effectively utilize the resource of system.
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, clear,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The process of launching of a kind of CoMP transmission mode that Fig. 1 provides for the embodiment of the invention, this process may further comprise the steps:
S101: when the QoS of business on a certain direction that the base station gets access to user terminal can't guarantee, detect the reason that causes this professional QoS to guarantee.
Wherein QoS can't guarantee, can be that the service quality QoS of this business on a certain direction is less than the service quality threshold value of setting.
S102: when confirming as the limited reason of interface-free resources; Reallocation message is sent to said user terminal in said base station; Carry the measurement configuration information that multipoint cooperative CoMP transmission mode is launched in the wherein said reallocation message; And the cell information that comprises in the measurement report according to said user terminal to send up, select the CoMP cell set, and to indicate the sub-district in the said CoMP cell set be that said user terminal carries out the CoMP transmission.
S103: when confirming as wired mouthful of resource-constrained reason, said base station selected CoMP base station is indicated the CoMP base station of selecting and is carried out the CoMP transmission as said user terminal certainly.
The QoS of business on a certain direction that concrete base station in embodiments of the present invention gets access to user terminal can't guarantee; Can be that user terminal is when detecting the QoS of own service on a certain direction and can't guarantee; Send the CoMP transmission to the base station and launch request; Wherein the traffic type information of carrying said business in the request is launched in this CoMP transmission, and traffic direction information, and the service quality QoS of business on a certain direction that makes the base station get access to this user terminal can't guarantee; Perhaps; Also can be the service quality QoS of business on a certain direction that equipment of the core network detects said user terminal can't guarantee the time, send the CoMP transmission to said base station and launch request, wherein; The identification information that carries said user terminal in the request is launched in said CoMP transmission; The traffic type information of said business, and traffic direction information, the service quality QoS of business on a certain direction that makes the base station get access to this user terminal can't guarantee; Perhaps, also can be that the QoS of business on a certain direction that base station self detects this user terminal can't guarantee.
