Background technology
3GPP (3rd Generation Partnership Project, third generation partner program) introduced DC-HSDPA (Dual Cell High Speed Downlink PacketAccess at Rel-8, two carrier wave high-speed downlink packet insert), utilize two descending adjacent carriers (main carrier and auxilliary carrier wave) to improve downlink bandwidth.Main carrier corresponding with service HS-DSCH (HighSpeed Downlink Shared Channel, high speed descending sharing channel) sub-district, the corresponding auxilliary service HS-DSCH of auxilliary carrier wave sub-district.Main carrier and auxilliary carrier wave are provided with HS-PDSCH (High Speed Physical Downlink Shared Channel respectively simultaneously, high-speed physical downlink shared channel (HS-PDSCH)) and HS-SCCH (High Speed Shared Control Channel, High-Speed Shared Control Channel), and independently dispatch.For having the terminal that receives the DC-HSDPA ability, can receive the HSDPA data at downlink main carrier to carry and descending auxilliary carrier wave simultaneously.
In order to realize the DC-HSDPA function, RNC (Radio Network Controller, radio network control entity) sets up cell by Iub mouth/Iur mouth with additional high-speed cell information Radio Link and disposes to Node B (NodeB) or another RNC.So-called additional high-speed cell information Radio Link is set up cell, mainly comprises: high-speed physical downlink shared channel (HS-PDSCH) Radio Link sign, cell ID, the auxilliary information on services of high speed descending sharing channel and the total maximum bit rate of terminal.
3GPP has introduced two carrier wave HSUPA (High Speed Uplink PacketAccess, High Speed Uplink Packet inserts) at Rel-9 and (DC-HSUPA), has utilized two up adjacent carriers (main carrier and auxilliary carrier wave) to improve upstream bandwidth.Up main carrier and upstream auxiliary carriers are provided with E-DPDCH (Enhanced Dedicated Physical DataChannel separately respectively, strengthen Dedicated Physical Data Channel) and E-DPCCH (Enhanced DedicatedPhysical Control Channel strengthens Dedicated Physical Control Channel).Downlink main carrier to carry and descending auxilliary carrier wave are provided with E-AGCH (Enhanced Absolute GrantChannel separately respectively, the enhancing absolute grant channel), E-RGCH (Enhanced Relative GrantChannel, wild phase is to authorization channel) and E-HICH (E-DCH HARQAcknowledgement Indicator Channel strengthens dedicated channel and mixes automatic repeat requests channel).Up main carrier is corresponding with downlink main carrier to carry, and upstream auxiliary carriers is corresponding with descending auxilliary carrier wave.Main carrier and auxilliary carrier wave are independently dispatched.For having the UE (User Equipment, subscriber equipment) that sends the DC-HSUPA ability, can send the HSUPA data at up main carrier and upstream auxiliary carriers simultaneously.
If have only a up-link carrier to dispose to terminal, then this up-link carrier is exactly up main carrier.When a plurality of up-link carriers are configured to this terminal, terminal has a service enhanced data channel sub-district on the up main carrier of reception from the absolute grant of Node B, terminal also has a service enhanced data channel sub-district on the auxilliary up-link carrier that receives from the absolute grant of Node B, the carrying frequency that the service enhanced data channel sub-district of service high-speed downlink shared channel sub-district correspondence is transmitted is exactly up main carrier.Service high-speed downlink shared channel Radio Link comprises all high-speed physical downlink shared channel (HS-PDSCH) physical channels of distributing to this terminal, so the high-speed physical downlink shared channel (HS-PDSCH) physical channel is exactly a downlink main carrier to carry.Service service high-speed downlink shared channel sub-district is some terminals to be carried out service high-speed downlink shared channel Radio Link transmit and receive.According to up main carrier definition, it is corresponding to downlink main carrier to carry.
In order to realize the DC-HSUPA function, RNC will add the enhanced data channel cell information and set up the request configuration to Node B (NodeB) or another RNC by Iub mouth/Iur mouth Radio Link.The so-called additional data channel cell information Radio Link that strengthens is set up request, mainly comprises: many sub-districts E-DCH (Enhanced Dedicated Channel strengthens dedicated channel) transmission bearer pattern and additional E-DCH cell information are set up.Additional E-DCH cell information foundation comprises additional E-DCH channeling duplex and sets up information and many sub-districts E-DCH information.Additional E-DCH channeling duplex is set up information and is comprised uplink special physical channel information, is the additional peculiar information of E-DCH Radio Link of foundation, additional E-DCH channeling duplex information and F-DPCH information.For setting up the additional peculiar information of E-DCH Radio Link is exactly the peculiar information of E-DCH additional radio links, and it comprises peculiar data entries 1 of E-DCH additional radio links and the peculiar data entries 2 of E-DCH additional radio links.The peculiar data entries 1 of E-DCH additional radio links has the following information: E-DCH additional radio links sign, cell ID, first Radio Link collection indication, propagation delay, initial downlink through-put power, primary common pilot control channel signal to noise ratio, some downlink channel power side-play amounts, and the medium of additional E-DCH are got involved the distinctive information of control dedicated stream.The peculiar data entries 2 of E-DCH additional radio links is the peculiar information of many sub-districts E-DCH Radio Link just.
Along with technical development, the multi carrier wave high-speed downlink packet access technique is introduced into existing system, this technology makes terminal to send data with high speed downlink packet access technology on two carrier waves or plural carrier wave, thereby make that the transmission rate of down link data is doubled, and corresponding descending carrier number can be one to four carrier wave.
The inventor finds: for the uplink carrier frequencies of each activation, if UE has disposed 3 to 4 descending service HS-DSCH sub-districts, in this case, up E-DCH control channel should be in the emission of the service HS-DSCH sub-district of pairing, and promptly up E-DCH Serving cell should have pair relationhip with descending service HS-DSCH.Up service E-DCH cell ID obtains by the cell ID cell in the peculiar information of E-DCH additional radio links in Radio Link request message or wireless link reconfigured request or the Radio Link increase request; The cell ID cell that service HS-DSCH cell ID is set up in the information by HS-DSCH sub-district additional radio links obtains.Descending introducing multicarrier (3 carrier waves or 4 carrier waves), main service E-DCH sub-district is identical with main service HS-DSCH cell ID, because descending have 2 or 3 auxilliary carrier waves, the auxilliary service of needs E-DCH cell ID is in a plurality of auxilliary service HS-DSCH cell IDs, but any one that can occur in the practical application in auxilliary service E-DCH cell ID and a plurality of auxilliary service HS-DSCH cell ID is all inconsistent, and causing can't be by auxilliary service HS-DSCH sub-district to the terminal transmission data.At this problem, effective solution is not proposed as yet at present.
