Abstract
The invention discloses a method and a device for processing resource admission in a long term evolution system. The processing method includes that when a service to be accessed in a cell passes admission control based on air interface resources, a base station of the cell performs resource admission processing based on adjacent cell interference to the service to be accessed; and when the service to be accessed passes resource admission based on the adjacent cell interference, subsequent service access processes are executed. The device comprises an air interface based resource admission module, an adjacent cell interference based resource admission module and a service access module. According to the processing method and the device, phenomena are avoided that when the air interface physical resources of an evolved Node B (eNB) cell meet access requirements and the quantity of non-high-interferential physical resource blocks doesn't meet the access requirements, system performances and system capacities sharply decline due to high interference after the service is accessed; and instability of a system is avoided, the quality of service is effectively guaranteed, a system resource usage ratio is increased, and satisfaction degrees of users are improved.
Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of Long Term Evolution (Long Term Evolution, LTE) processing method of resource and admission and device in the system.
Background technology
In any GSM, the physical resource of sub-district all is limited in the system, and the LTE system is no exception.In the LTE system, when the UE access network, will take the corresponding physical resource in sub-district among the eNB (evolved Node B, evolved base station).The physical resource here mainly is meant the Radio Resource that among the eNB eat dishes without rice or wine in the sub-district, specifically, is exactly PRB (Physical Resource Block, the Physical Resource Block) resource of sub-district up-downgoing.Wherein, the bandwidth that how much is decided by the sub-district of PRB resource in the sub-district.The bandwidth of sub-district is big more, and the corresponding available PRB resource of up-downgoing is just many more, that is to say that the interface-free resources of sub-district is just many more.But; Even under the configuration of full bandwidth; The physical resource of eating dishes without rice or wine in the sub-district also only can be allowed the user equipment (UE) or the professional access of some, if when UE or service access network, do not do the admittance control based on interface-free resources, will cause exhausting rapidly of interface-free resources; And then cause the interface-free resources traffic overload, cause system's heavy congestion.Experience upward from the user, meeting traffic affecting service quality seriously reduces user experience.So, when UE or service access, can carry out remaining the PRB resource quantity usually business is admitted control: when judging that new business to be accessed is counted the PRB number that takies less than the remaining PRB that eats dishes without rice or wine, allow this service access based on eating dishes without rice or wine; Otherwise, then refuse the access of this business.
In the networking and application of reality; For the LTE system; Though each user can pass through the good orthogonality of OFDMA (Orthogonal Frequency Division Multiple Access, OFDM) technology acquisition in E-UTRAN (EvolvedUniversal Terrestrial Radio Access Network, the general continental rise wireless access network of the evolution) sub-district; But the interference of minizone but can not be ignored, and this phenomenon is more outstanding under the scene of identical networking.Therefore; There is such scene; Though the access of the enough current business of surplus resources of eating dishes without rice or wine in the sub-district, because the existence that disturb the adjacent area; Will inevitably cause to have influence on the transmitting power at sub-district and terminal and the coverage of sub-district after this service access, finally influence the capacity and the performance of system.Can cause exactly that specifically neighbor cell systematic function and capacity all sharply descend; Simultaneously, based on unique user, also very serious for the influence of service feature and quality; Professional QOS (Quality of Service, service quality) can't be met and ensure especially.
Summary of the invention
The technical issues that need to address of the present invention provide the processing method and the device of resource and admission in a kind of LTE system, when handling resource and admission, fail to consider the influence that neighbor cell interference is brought and cause the sharply problem of decline of systematic function and capacity to solve eNB.
