Description
Technical field
The present invention relates to enhancement type special channel (E-DCH) the transmission bearer technology in the wireless communication system, relate in particular to a kind of method and system that uses the E-DCH transmission bearer of changing.
Background technology
In wireless communication system, category-B interconnected (IUB, Interconnection of type B) interface is the logic interfacing between radio network controller (RNC, Radio Network Controller) and the Node B.For specific Node B set, a kind of role of RNC is control radio network controller (C-RNC, Controlling Radio Network Controller).For any one Node B, have and only have a C-RNC, and C-RNC has all controls of the logical resource of this Node B.
In wireless communication system, the interconnecting interface between the RNC (IUR, Interconnection ofRNC) is the interface that RNC is used for carrying out with other RNC signaling and data interaction, is tie interconnected between the RNS.When a terminal has been set up the connection of wireless access network, and when the IUR interface has produced soft handover, will use resource, and different RNC is serving as different roles at this moment more than a RNC:
Serving RNC is the RNC that keeps this terminal to be connected with the interface of core net, the data transmission between responsible core net and the terminal and with the passing on and receive of the interface signaling of core net; Be responsible for carrying out Radio Resource control, the data of air interface carried out the processing of layer two, and carry out basic radio resource management operations, as the parameter of switch decision, exterior ring power control, RAB to the conversion of the transport channel parameters of eating dishes without rice or wine etc.;
Drift Radio Network Controller is meant Serving RNC other RNC in addition, and it controls the sub-district that this terminal is used, and if desired, Drift Radio Network Controller can carry out grand diversity and merge; Unless this terminal is used Common transport channel, otherwise Drift Radio Network Controller can not carry out layer two processing of end face data, and the route of passing through the IUR interface of the data transparency of just will eating dishes without rice or wine passes to Serving RNC.The RNC of a terminal can be more than one.
The target of high-speed uplink packet access technique is to improve capacity and data throughout at up direction, reduces the sluggishness in the dedicated channel.Introduced a new transmission channel, be enhancement type special channel (E-DCH by high-speed uplink packet access technique, Enhanced Dedicated Channel), realization to physical layer and media access control layer improves, and can reach the theoretical maximum upstream data rate is 5.6 MBPSs.High-speed uplink packet access technique has kept the characteristic of soft handover.The media access control protocol data unit that air interface receives, demultiplexing is a media access control flow, with the form of E-DCH Frame (Data Frame) from Node B via IUB interface or RNC via the IUR interface, transmission bearer (each media access control flow has the IUB interface and/or the IUR interface transmission bearer of a correspondence) by the media access control flow correspondence is transferred to Target RNC (being another one RNC).
Along with technical development, two carrier wave high-speed uplink packet access techniques (this technology makes terminal to send data with high-speed uplink packet access technique on two carrier waves, thereby makes uplink data rate be doubled) wish to be introduced into existing system.The carrier wave that comprises High-Speed Dedicated Physical Control Channel in two carrier waves is called main carrier, and another one carrier wave remaining in two carrier waves is called auxilliary carrier wave.
There is and has only a carrier wave sub-district, so use two carrier wave high-speed uplink packet access techniques, needs two sub-districts at least, and the carrier wave of one of them sub-district is as main carrier, and the carrier wave of another one sub-district is as auxilliary carrier wave.Two sub-districts like this are called double sub-district (Dual-cell).
For a terminal, each layer carrier wave in two carrier waves all has oneself independently E-DCH Active Set.Different districts may be in different Node B in the E-DCH Active Set.Each different districts in the E-DCH Active Set of each layer carrier wave wherein has and has only a sub-district to send and the reception absolute grant, and this sub-district is called Serving cell.Main carrier Serving cell and auxilliary carrier service sub-district must be in same Node B, and this Node B is called " serving node B ".
In existing two carrier wave high-speed uplink packet access technique, definition " E-DCH transmission bearer pattern " is the use pattern of the transmission bearer of carrying E-DCH Frame (Data Frame), and two kinds of patterns are arranged: " E-DCH upstream multiplexer mode (E-DCH UL Flow Multiplexing pattern) ", " separating Iub/Iur transmission bearer pattern (Separate Iub/Iur Transport Bearer pattern) ".Wherein, E-DCH UL FlowMultiplexing pattern is meant in two carrier waves that (main carrier and auxilliary carrier wave) receives on all up-link carriers same medium access control (MAC, Media Access Control) is banished on a transmission bearer and sends; Separate Iub/Iur Transport Bearer pattern is meant in two carrier waves that (main carrier or auxilliary carrier wave) receives from each different up-link carrier each MAC banishes at a transmission bearer and sends.
Up multiplexed information in the definition E-DCH Frame (Data Frame) is: when E-DCH transmission bearer pattern is to use " E-DCH UL Flow Multiplexing pattern ", up multiplexed information is used in reference to and is shown the carrier identification that this Frame receives, as main carrier or auxilliary carrier wave; When being to use " Separate Iub/Iur Transport Bearer pattern " when " E-DCH transmission bearer pattern ", up multiplexed information is empty, and the perhaps up multiplexed information side of being received is ignored.
In the prior art, whether support two kinds of patterns of E-DCH transmission bearer pattern, belong to a kind of ability of sub-district.Some sub-district is all supported for two kinds of patterns of E-DCH transmission bearer pattern; Some sub-district all is unsupported for two kinds of patterns of E-DCH transmission bearer pattern; Wherein a kind of pattern of E-DCH transmission bearer pattern is only supported in some sub-district.
So when soft handover, need to consider the tenability for two kinds of patterns of E-DCH transmission bearer pattern of candidate cell.For a terminal, each layer carrier wave in two carrier waves all has oneself independently E-DCH Active Set, and each different districts all needs to possess identical one of them for E-DCH transmission bearer pattern and plants the tenability of pattern in the E-DCH Active Set of each layer carrier wave.Like this, for soft handover, will be great restriction.
For example: use up pair of ZAP in the double sub-district (Dual cell) that terminal of RNC control is made of sub-district 1 and sub-district 2 in serving node B.At this moment, the carrier wave of sub-district 1 is the up pair of main carrier in the carrier wave, and the carrier wave of sub-district 2 is the auxilliary carrier waves in the up pair of carrier wave, and " E-DCH UL Flow Multiplexing pattern " all supported in sub-district 1 and sub-district 2.In this process, it is " E-DCH UL Flow Multiplexing pattern " that E-DCH transmission bearer pattern is used in the RNC decision-making, and is notified to serving node B.When this terminal moves to sub-district 3, the signal of sub-district 3 is become better and better, but " E-DCH ULFlow Multiplexing pattern " do not supported in sub-district 3, only supports " Separate Iub/Iur Transport Bearer pattern ", and RNC can't add sub-district 3 in the Active Set of soft handover so.In the network operation of reality, such scene usually takes place, owing to limited soft handover, will can not get the gain of grand diversity, and systematic function will be a greater impact.
