Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of baseband pool shared resource distribution method and device.
Background technology
In the existing network of communication system, different geographic regions, different time sections, number of users or business demand amount are not quite similar, in some interregional phenomenon that exists telephone traffic to move repeatedly by the time.As the teaching district and the dormitory area of colleges and universities, by day, teaching district telephone traffic is big, and the dormitory area telephone traffic is little; And at night, swarming appears in the user, and teaching district's telephone traffic reduces, and the dormitory area telephone traffic increases, and has the effect of traffic complementation between the two, and the phenomenon that this user is moved repeatedly in the minizone is referred to as the tidal phenomena of communicating by letter and covering usually.
At present, network mostly adopts fixing planning, each department at each base-band resource constantly according to the greatest requirements fixed configurations, this just might cause the different districts base-band resource of same base station node B idle with anxiety situation and deposit.Thereby, to the base-band resource fixed configurations, in the utilization of resources, be undoubtedly a kind of waste.Thus, introduced the notion of baseband pool resource-sharing, be about to all base-band resources and concentrate in together by the unified scheduling of Node B and distribute, realized management dynamically, specified as follows at Node B.
As shown in Figure 1, the sub-district under Node B can be planned and be divided into a plurality of cell set Cell Group, can be planned a plurality of sub-district cell under each cell set.TD-SCDMA (Time Division-SynchronousCode Division Multiple Access, TD SDMA) in the system, can plan a plurality of carrier waves under each sub-district, wherein main carrier has and has only 1, and auxilliary carrier wave can have 0 or one or more.Resource in the baseband pool of Node B is unit with the carrier wave, shares in the cell set scope.
For multi-carrier-wave TDD 128 sub-districts, the auxilliary carrier wave of sub-district can be divided into and share auxilliary carrier wave and share auxilliary carrier wave.When setting up in the process in the sub-district, RNC (Radio Network Controller, radio network controller) activates the main carrier of sub-district and can not share auxilliary carrier wave, and Node B distributes base-band resource for it; But RNC does not activate the auxilliary carrier wave of sharing of sub-district, and Node B can not distribute base-band resource for it.
After the sub-district was set up, RNC was according to cell telephone traffic amount situation, and in conjunction with the resource operating position of baseband pool, whether decision activates the auxilliary carrier wave of sharing of sub-district.If RNC has activated the auxilliary carrier wave of sharing of sub-district, then NodeB distributes base-band resource for it.
After having activated the sub-district and sharing auxilliary carrier wave, RNC also can be according to cell telephone traffic amount situation, and in conjunction with the resource operating position of baseband pool, determines the auxilliary carrier wave of sharing that whether deexcitation activated.If the RNC deexcitation sub-district activated share auxilliary carrier wave, then Node B is recovered as the base-band resource of its distribution.
