Description
Technical field
The present invention relates to the mobile communication technology field, especially a kind of network is the terminal distribution Radio Resource, the method and system of foundation two years or overloading Temporary Block Flow (Temporary Block Flow is called for short TBF).
Background technology
GPRS (General Packet Radio Service is called for short GPRS) is the packet data exchanged technology of introducing in global system for mobile communications (Global System for Mobile communications is called for short GSM) network.This technology is superimposed on the gsm system, adopts based on the forwarding of packet data package and the statistic multiplexing of channel, and the data service that existing GSM is provided has leaped more than the 100Kbps from 9.6Kbps first, has prolonged the useful life of GSM.But because GPRS still adopts the GMSK (Guassian Minimum Shift Keying) the same with GSM (Gaussian Minimum Shift Keying is called for short GMSK) modulation system, transmission rate can't reach the 2Mbps that satisfies the 3G business need.In order fully to satisfy the bandwidth demand that following radio multimedium is used, a kind of transitional scheme from GPRS to 3G has been proposed---Enhanced Data rates for GSM Evolution (Enhanced Data rates for GSM Evolution is called for short EDGE).It and universal mobile telecommunications system (Universal Mobile TelecommunicationsSystem, be called for short UMTS) shared core net, by introducing the Iu interface, be evolved to GSM EDGE Radio Access Network (GSM EDGE Radio Access Network is called for short GERAN).EDGE is a kind of data enhancement mode mobile communication technology based on the GSM/GPRS network, is called the 2.75G technology by people again usually.This technology mainly is to use broadband service, can allow the network of use 800,900,1800,1900MHz frequency range that the partial function of 3G (Third Generation) Moblie network is provided.
In order further to improve the data transmission bauds of EDGE system, a kind of descending two (or overloading) transmission technologys of carrying have now appearred.For traditional E DGE system, terminal can only be passed through a carrier frequency receiving block data, bandwidth of operation only is 200KHz, theoretic maximum data transfer rate is 473.6kbps, and descending two (or overloading) transmission technology of carrying has broken through this restriction, and terminal can be carried out the reception of downlink grouped data on more than one carrier frequency simultaneously.Bandwidth of operation just becomes 200*N KHz (N is the carrier frequency number), and corresponding message transmission rate is also according to the proportional improve of carrier frequency number.Still with present enhancing GPRS (Enhanced GPRS, abbreviation EGPRS) system is an example, distributing the theoretical maximum velocity of 8 time slots on the carrier frequency is 473.6kbps, if MS can receive on 2 carrier frequency simultaneously, speed can reach the requirement of 3G system to speed near 1M so.
If network equipment and terminal are all supported descending two (or overloading) function of carrying, network equipment can be set up two TBF (or overloading TBF) of carrying for the Radio Resource of two or more carrier waves of terminal distribution, and terminal receives data simultaneously on two or more carrier waves.And network equipment is the terminal distribution resource, and the process meaning of setting up two TBF (or overloading TBF) of carrying is for assigning.The appointment process can support that with network equipment and terminal descending two carrying is example specifically as shown in Figure 1, may further comprise the steps:
After step 103, terminal received assignment messages, descending two the carry Radio Resources indicated according to this assignment messages went to receive data;
In addition, in order further to strengthen the receptivity of terminal, in GERAN, introduced terminal receiver diversity (MS Receiver Diversity is called for short MSRD) technology.For the terminal of supporting MSRD, need two covers and receive antenna, and receive the same signal that network sends by this two covers antenna.By reception diversity technology, make the terminal of MSRD can obtain better receptivity.In the relatively poor place of wireless environments such as cell edge, effect is especially remarkable.Existing terminal can not be operated in MSRD and descending two carrying under (or overloading) pattern simultaneously, when terminal wireless environment of living in relatively poor, in the time of must relying on MSRD could satisfy the basic demand of upper-layer service (leave the MSRD pattern and just can not normally receive the signal that network issues), if at this moment terminal is in the MSRD pattern, network equipment can't know which kind of pattern is terminal adopted, when network equipment is that terminal is assigned descending two TBF (or overloading TBF) of carrying, terminal can be according to assigning order to leave the MSRD pattern that is in, being converted to two or more carrier waves receives, because radio condition can't support normally to receive network signal, therefore can cause service fail.
