Description
Technical field
The present invention relates to moving communicating field, particularly a kind of fault carrier frequency restoration methods, system and base-band resource collocation method.
Background technology
In multi-carrier frequency system, a plurality of carrier frequency are all supported in each sub-district under the base station (Node B), and one of them carrier frequency is a main carrier frequency, and remaining carrier frequency is an assistant carrier frequency.
After the main carrier frequency of sub-district broke down, (Radio Network Controller, RNC) this sub-district was unavailable by resource status Indication message notice radio network controller for Node B.The do not reallocate resource of this sub-district of RNC, and the associated user in this sub-district of initiating to reset discharge these users' wireless network layer and transport network layer resource.RNC further discharges this local resource by the sub-district delete procedure, if RNC or Node B also have wireless network layer or the transport network layer resource that does not discharge, then carries out this locality separately and discharges.After the deletion of sub-district, if Node B has detected available resources, then by resource status Indication message notice RNC, RNC sets up process by the sub-district and sets up the sub-district related resource.If the result that the sub-district is set up has only the part carrier frequency to set up successfully, the Node B assistant carrier frequency of notifying RNC to break down by the resource status Indication message then, RNC identify the use that degrades of this sub-district.
After the assistant carrier frequency of sub-district broke down, Node B was unavailable by this assistant carrier frequency of resource status Indication message notice RNC, the sub-district use that degrades.RNC is the resource of distribution malfunctions carrier frequency no longer, and the associated user on the fault carrier frequency of initiating to reset, and discharges these users' resource.After Node B detects the fault carrier frequency hardware reset,, following two kinds of processing modes are arranged according to the difference of Node B ability:
If 1 Node B supports to recover the configuration of assistant carrier frequency Radio Resource, then can use by this assistant carrier frequency of resource status Indication message notice RNC, cell status recovers normal (if also have other assistant carrier frequency unavailable, then this sub-district still is in the user mode that degrades); RNC can distribute the resource of this assistant carrier frequency.
If the configuration that 2 Node B do not support to recover the assistant carrier frequency Radio Resource continues to judge whether the hardware resource of all fault carrier frequency of sub-district all recovers.If all recover, then trigger the handling process of above-mentioned main carrier frequency fault, promptly delete and rebuild the sub-district; If do not recover resource in addition, then continue to wait for this sub-district use that degrades simultaneously.
As seen, after main carrier frequency breaks down, need the deletion sub-district to activate again again, can disconnect the connection of all users in the sub-district simultaneously.After assistant carrier frequency breaks down, its loaded service (particularly high demand business) can not be recovered timely, for example, in the R5 version, if have physical down link sharing channel (Physical Downlink Shared Channel, PDSCH) assistant carrier frequency breaks down, and need rebulid PDSCH, and may exist free time or professional less assistant carrier frequency not to be fully utilized in this fault treating procedure.The use that these have all influenced the user has reduced the service quality of network.
On the other hand, at present network is taked the planning fixed mostly, and each department are fixed configurations at each base-band resource constantly, for example are configured according to greatest requirements.But different geographic regions, different period, number of users or traffic needs are not quite similar.For example certain sports buildings can be fixed on certain period arrangement hot race in a day, attracts large quantities of spectators; The stream of people is bigger for certain office building, market meeting on daytime, and is close to evening unmanned; But the situation in certain bar district is just on the contrary with office building.This just might cause idle with the nervous situation of the different districts base-band resource of same Node B and deposit, thereby, to the base-band resource fixed configurations, in the utilization of resources, be undoubtedly a kind of waste.
