Description
Technical field
The present invention relates to the communication technology of wireless access network in Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, be meant a kind of communication means of finishing each layer protocol stack processing by base station side especially.
Background of invention
In existing Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, the network configuration of wireless access network (RAN) as shown in Figure 1, wireless access network 100 mainly comprises base-station node ( Node B) 102 and 101 two kinds of entities of radio network controller (RNC).Include a plurality of sub-districts 103 among the Node B102, and a RNC101 can control a plurality of Node B102 simultaneously, this is a kind of typical centralized network structure.
At present RAN structure, the protocol stack of its Access Layer constitutes as Fig. 2, shown in Figure 3.Fig. 2, Fig. 3 are respectively the Access Layer protocol stack distributed architecture schematic diagrames of user's face and chain of command, the part in dotted line left side is represented the corresponding relation figure of layering between user terminal (UE), Node B and the RNC among Fig. 2, Fig. 3, the part on dotted line right side is the layering transport model between UE, Node B and the RNC, wherein, Uu represents the interface between UE and the Node B, and Iub represents the interface between Node B and the RNC.As can be seen from the figure, base-station node (Node B) in the existing Access Network is only handled physical layer information, RNC then handles the full detail of physical layer, medium access control (MAC), Radio Link control (RLC) layer and radio resource control (RRC) layer or packet data compression protocol (PDCP) layer, wherein, rrc layer belongs to chain of command, and the PDCP layer belongs to user's face.That is to say that the Node B of existing Access Network only handles physical layer information, other high layer informations that insert part are fully by the RNC control and treatment.Therefore, communication process between existing UE, Node B and the RNC generally is such: when UE has service request, send out request message earlier and give Node B, Node B reports RNC with this request, carry out the management and dispatching and the distribution of resource by RNC, and the realization of control whole service process, Node B is only responsible physical connection and data signaling transmission in whole process.
Because transfer of data and signaling any in the communication system are controlled the support that all will depend on each layer protocol, so, based on above-mentioned protocol stack structure, in data transmission procedure, the UE side is carried out mailing to RLC after the head compression is handled to data by PDCP earlier; RLC implements to mail to MAC after burst and the cascade; MAC selects suitable transformat combination (TFC) according to the transmission format composite set (TFCS) of current data packet and configuration; Carry out being sent to the NodeB side after the coded modulation according to selected TFC by physical layer at last; Node B side is sent to RNC according to the coded system of determining with data by physical layer; RNC side order by PHY layer, MAC layer, rlc layer and PDCP layer do demodulation coding, separate combination, recombination data and decompress after, obtain the packet that UE sends out.
Equally, in the signaling transmission course, the UE side by RRC, RLC, MAC and PHY successively with signaling message encapsulation, burst and cascade, the suitable TFC of selection, at last by being sent to Node B side after the selected TFC coded modulation; Node B side is sent to RNC according to the coded system of determining with this signaling message by physical layer; RNC side order is done demodulation coding, is separated combination, after recombination data and the decapsulation, obtained the signaling message that UE sends out by PHY layer, MAC layer, rlc layer and rrc layer, and then, RNC handles accordingly according to this signaling message.
But, in above-mentioned transmission course, because Node B only handles physical layer protocol in the existing protocol stack, in case the adaptive technique that needs the employing resource management to adjudicate all need realize in RNC, network must be through RNC to Node B to terminal, Node B is to two stages of terminal, vice versa, thereby cause long time delay, and reduced the disposal ability of Node B.As seen, all are inserted high-risely all be placed on protocol architecture among the RNC the incompatibility high speed data transfer, be similar to the technology of self adaptation coordination, FEEDBACK CONTROL in employing after, this kind protocol architecture can not guarantee high speed, efficient, thereby is difficult to adapt to the demand of high speed data transfer.
