Description

The channelized code resource adjusting method of high speed descending grouping access system
Technical field
The present invention relates to the channelization code resource that grouping inserts in a kind of 3-G (Generation Three mobile communication system) and distribute and connection control method, particularly relate to a kind of high speed downlink packet and insert (HSDPA High SpeedDownlink Packet Access) channelization code resource distribution and service access control method in 3-G (Generation Three mobile communication system).
Background technology
In 3-G (Generation Three mobile communication system),, the business difference is conversation class, stream class, interactive class and four kinds of types of service of background classes according to sensitivity to time delay.Wherein, session service is the most responsive to time delay, secondly is stream class service and interaction service, and background business is least responsive to time delay.From the angle of carrying, session service has strict delay requirement, needs the constant bit rate to transmit, and is applicable to usually to be carried on the dedicated channel; Interaction service and background business are insensitive to time delay, belong to the COS of " doing one's best ", but the data integrality is had higher requirements, and can be carried on special use/public/shared channel; Stream class service is more special, though also belong to real time business, transmission bit rate is had certain requirement, and what it more was concerned about is the variation of propagation delay time, can adopt special use or shared channel to transmit.
In order to satisfy more faster data business demands, 3-G (Generation Three mobile communication system) has been introduced the HSDPA technology.HSDPA obtains downlink transmission data rate at a high speed by adopting the quick retransmission mechanism of physical layer, transmission folding and the adaptive modulation coding mode of rapid link by base station controller (Basestation Controller is hereinafter to be referred as NodeB) control.
The HSDPA technology has been introduced three kinds of new channels: high speed descending sharing channel (HS-DSCH HighSpeed Downlink Share Channel), High-Speed Shared Control Channel (HS-SCCH HighSpeed Share Control Channel) and High-Speed Dedicated Physical Control Channel (HS-DPCCHHigh Speed Dedicated Physical Control Channel).
HS-DSCH is used for the user data of carries downlink, and its corresponding physical channel is HS-PDSCH (high-speed physical downlink shared channel (HS-PDSCH)).
HS-SCCH is used to carry the physical layer that is used on the HS-DSCH decoding and controls signaling.If take place to retransmit or the erroneous packet data, this channel also comprises possible physical layer data combination.
HS-DPCCH is used to carry uplink control signaling, and promptly ARQ (repetitive requests automatically) confirms and the downlink quality feedback information.
The basic principle of operation of HSDPA as shown in Figure 1.NodeB102 assesses quality of channel according to power control, ACK/NACK (affirmation of ack/nack) ratio, quality of service and the specific field feedback of HSDPA that each is carried on the user terminal (UE) 101 on the HSDPA, and dispatches and the link circuit self-adapting adjustment according to the dispatching algorithm and the User Priority algorithm of current employing.UE101 monitors the HS-SCCH channel, determines the code word that despreading HS-DSCH is required with a time slot, utilizes the specific mask of UE101 to judge whether the data of reception are oneself.If then utilize the data on the message pick-up HS-DSCH on the HS-SCCH.UE101 receive produce after the data ACK/NACK reflect the grouped data decoding and merge after CRC (cyclic check code) check results, the quality condition of current down link is indicated in and downlink quality indication (CQI).
In a network of supporting HSDPA, each HSDPA sub-district can distribute at most 15 SF (spreading factor) be 16 HS-PDSCH channel for HSDPA user's use, (code check is 3/4,16QAM) to reach the highest message transmission rate 10Mbit/s.RNC (radio network controller) will be relevant with HS-DSCH HS-PDSCH information (HS-PDSCH channel code number and the initial channel code of Start CodeNumber) and HS-SCCH channel set information give NodeB by the order configuration of Iub message together; The HS-PDSCH channel code that NodeB uses number is: C 16, start code number, C 16, startcode number+1, C 16, start code number+N-1NodeB is in the dispatching cycle of each TTI (Transmission Time Interval), according to oneself scheduling strategy for each UE101 distributes operable HS-PDSCH channel code, concrete yardage can be whole HS-PDSCH channel code, also can be its subclass.When NodeB102 distributes the real channel code that uses to UE101, adopt P (initial channel code), 0 (channel code number) notice UE101, which bar channel code what really use to its is.HS-PDSCH distributes the size that how much can react this cell data flow of bar number.
According to present common way, the HS-DSCH channelization code resource disposes to NodeB according to the mode of the network packet flow of pre-estimating with static state.Because the downgoing channelized codes resource-constrained of each sub-district, if employing static configuration, for the channelization code resource that high speed business distributed also can't discharge the professional use to non-HSDPA after Packet Service finishes, directly influenced system channel sign indicating number efficiency of resource so.And the SF of HS-DSCH channel code is 16, if reach the flank speed (10.8Mbps) of HSDPA, then needing is 15 HS-PDSCH of its configuration.If adopt this static configuration, then can't guarantee of the access use of enough downgoing channelized codes resources for non-HSDPA business.What and the method for salary distribution of HS-DSCH channelization code allocation directly have influence on the access of other non-HSDPA business in the sub-district, and then influence the capacity of sub-district.Therefore need a kind of effective method that the number of channelization codes of distributing to HS-DSCH is adjusted dynamically; When inserting, Packet Service increases the HS-DSCH channelization code resource according to rate requirement; Report reduces the HS-DSCH channelization code resource according to flow to insert the back at Packet Service, thereby improves the utilization ratio of channelization code resource, reaches the balance of power system capacity and system data flow.
