The present invention mainly is, static traffic user and the dynamic service user who satisfies the isolation condition adopted the space division multiplexing technology, thereby can use the shared code source of static traffic CU to carry out the transmission of dynamic service data, thereby improve the time-frequency code resource utilization of residential quarter, improve the call completing rate KPI of residential quarter, reduce the refusal access that causes because of the resource obstruction.
In an embodiment of the present invention, static traffic can comprise that the professional and non-scheduled HSUPA of R4 is professional, and dynamic service can comprise that the HSUPA of scheduling is professional and HSDPA is professional.And, indoor distributed system adopts the BBU+RRU scheme to carry out the multichannel covering in the present invention, owing to have larger isolation between the floor, so the overlay area of each passage is relatively independent, can use the space division multiplexing technology, Effective Raise code resource utilization.If outdoor system then can adopt smart antenna to cover, for the larger user of space isolation, also can use the space division multiplexing technology, further improve the code resource utilization.
As shown in Figure 1, for the invention process static traffic and the method flow diagram of dynamic service space division multiplexing, the method may further comprise the steps:
Step S101 divides the code source of residential quarter, obtains the code source configuration information, and shared code word acquiescence wherein is as the H resource.As one embodiment of the present of invention, before the residential quarter is set up, code source to the residential quarter is planned, particularly, the code source of residential quarter can be divided into high-speed downlink packet access HSDPA reserved codeword, high speed uplink packet access HSUPA reserved codeword, R4 reserved codeword, the shared code word of R4/HSDPA and R4/HSUPA and share code word.Certainly, those skilled in the art also can select other dividing mode, if but these dividing mode and dividing mode of the present invention serve the same role, then also should be included within protection scope of the present invention.
Step S102, code source configuration information by OMCR Operation and Maintenance platform notice RNC current area, share code source such as R4 reserved codeword resource, HSDPA reserved codeword resource, HSUPA reserved codeword resource and R4/HSDPA, R4/HSUPA shares the configuring condition of code source etc.
Step S103 is disposed the code source configuration information to NodeB by RNC.In embodiments of the present invention, when RNC is configured the shared channel resources of NodeB, R4/HSDPA need to be shared the shared code channel resource of code channel resource and R4/HSUPA gives tacit consent to as the H resource distribution to NodeB, namely in the present invention NodeB to be indifferent to which channel be that R4/HSDPA shares code channel, R4/HSUPA shares code channel, which is that HSDPA, HSUPA keep code channel, when scheduling H resource, the shared code channel of R4/HSDPA, R4/HSUPA are shared code channel be considered as HSDPA, HSUPA reservation code channel, the preferential use.
Step S104, when static traffic user (for example R4 service-user) request access, NodeB reports RNC with the area of space under this user.
Step S105, RNC are this static traffic user assignment code source.When RNC was this static traffic user assignment code source, at first RNC used the code source that R4 keeps, and only has when R4 reserved codeword resource is inadequate, just used R4/HSDPA to share code source, the shared code source of R4/HSUPA.If the shared code source of use R4/HSDPA, R4/HSUPA share code source then continue execution in step S106, if do not use R4/HSDPA to share code source, the shared code source of R4/HSUPA, use R4 reserved codeword resource then to be prior art, do not repeat them here.Preferably, RNC is when distributing shared code source, already present all dynamic service users' affiliated area of space in the poll residential quarter guarantees that as far as possible the time-frequency code resource of new access user is different from the area of space under the dynamic service user, improves the space division multiplexing probability.
Step S106, when static traffic takies shared code word, NodeB judges between static traffic user and the dynamic service user whether satisfy insulated degree requirement, for example can by certain space isolation judgment criterion determine the H resource whether can with the professional space division multiplexing of R4.If judge and do not satisfy insulated degree requirement, then when the H scheduling of resource, do not re-use the shared code word that described static traffic takies.
Step S107, if insulated degree requirement is satisfied in judgement, then NodeB carries out space division multiplexing to static traffic user and dynamic service user, the shared code word of using static traffic to take when the H scheduling of resource.
In one embodiment of the invention, when described static traffic is that R4 is professional, described static traffic user is the R4 service-user, described dynamic service is that HSDPA is professional, when described dynamic service user is the HSDPA service-user, if R4 service-user and described HSDPA service-user satisfy insulated degree requirement, the shared code source that then continues to use the R4 service-user to take carries out DSCH Downlink Shared Channel DSCH transfer of data, carries out descending space division multiplexing.As shown in Figure 2, schematic diagram for embodiment of the invention scheduling H resource, for the static traffic user who satisfies the isolation condition and dynamic service user, the MaC scheduling continues to use the code source of static traffic CU to carry out the DSCH transfer of data, carries out descending space division multiplexing.
In another embodiment of the present invention, when static traffic is that R4 is professional, the static traffic user is the R4 service-user, dynamic service is that HSUPA is professional, when the dynamic service user is the HSUPA service-user, if R4 service-user and HSUPA service-user satisfy insulated degree requirement, then the MaC scheduling shared code source that continues to use the R4 service-user to take strengthens dedicated channel E-DCH transfer of data, carries out up space division multiplexing (can with reference to figure 2).
In another embodiment of the present invention, when static traffic is that non-scheduled HSUPA is professional, the static traffic user is non-scheduled HSUPA service-user, dynamic service is professional for scheduling HSUPA, when the dynamic service user is scheduling HSUPA service-user, if non-scheduled HSUPA user and described scheduling HSUPA service-user satisfy insulated degree requirement, the transfer of data of then using the shared code source of non-scheduled HSUPA CU to dispatch the HSUPA service-user is carried out space division multiplexing.
