Description
Technical field
The present invention relates to 3G (Third Generation, the third generation) communication system of field of wireless communication, relate in particular to a kind of method at HSPA (High Speed Packet Access, high-speed packet inserts) channel Signaling Radio Bearer.
Background technology
HSPA comprises 3GPP (Third Generation Partnership Projects, the 3G (Third Generation) Moblie partnership) the big technology of 2 in the protocol architecture, the i.e. HSDPA that in the Rel-5 version, formulates (HighSpeed Downlink Packet Access, high speed downlink packet inserts) technology and E-DCH (the Enhanced Dedicated Channel that in the Rel-6 version, formulates, strengthen dedicated channel) technology, be commonly referred to HSUPA (High Speed Uplink Packet Access, high speed uplink packet inserts) technology.The introducing of HSPA technology makes the data service bearing capacity of 3GPP3G network strengthen greatly, and the availability of frequency spectrum also is significantly improved.With TD-SCDMA (Time Division-Synchronous CodeDivision Multiple Access, TD SDMA) system is example, and HSDPA can provide the downlink data throughput of the highest 2.8Mbps; HSUPA can provide the upstream data throughput of the highest 2.23Mbps:
At down link: utilize 5ms TTI (Transmission Time Interval, Transmission Time Interval), AMC (Adaptive Modulation and Coding, adaptive coding and modulating), HARQ (HybridAutomatic Repeat Request, mix automatically and retransmit), based on key technologies such as the scheduling of Node B (base station) and shared channels, HSDPA can the fast adaptation wireless environment variation, dynamically adjust the down link data throughput; By transferring Traffic Channel to " sharing " from " special use ", make more user share descending wireless bandwidth, effectively improved wireless resource utility efficiency.
Up link: by 5ms TTI, HARQ and based on the key technologies such as scheduling of Node B, HSUPA can better control the uplink noise lifting, has effectively utilized the ascending idle port capacity, has improved the uplink data throughput.
When initial design HSPA technology, application scenarios mainly is positioned on the high-speed data service, comprise that web browses, video, multimedia messages and other IP-based business.A series of studies show that carried out the delay that the signaling transmission can improve signaling greatly on HSPA in the recent period, improves user's satisfaction.
Wave point UE (User Equipment, subscriber equipment) typical RRC (the Radio Resource Control of initiation connection request, Radio Resource control) signaling process figure can set up the calling of a circuit domain or the data service of packet domain by this flow process UE as shown in Figure 1:
Step 101, UE initiates the RRC connection request, be with to connect and set up reason and type of call (speech, video flowing etc.), simultaneously with on whether support the capability indication information of HSPA, concrete capability indication information can for: do not support HSPA, only support HSDPA, support HSDPA and E-DCH;
Step 102, RNC (Radio Network Controller, radio network controller) admits control, if allow UE to insert, to send the RRC connection and set up message, wherein mainly carry the relevant information of SRB (Signaling Radio Bearer, Signaling Radio Bearer) configuration;
Step 103 after UE finishes configuration, sends RRC connection foundation and finishes, simultaneously with the wireless access capability information that goes up oneself on newly-built SRB;
Step 104, UE sends initial directly message transfer (the back flow process slightly).
By existing RRC signaling process, if UE supports HSPA, RNC can be that the UE configuration is mapped to the up Signaling Radio Bearer on the E-DCH when setting up in step 102 transmission RRC connection so.Can find but study existing TD-SCDMA HSPA system, can not well support this transmission mechanism at present.This be because, UE is when the E-DCH transmitting data, the control channel E-UCCH that follows (enhancing ascending control channel) it may be noted that the control signaling that this transmission is relevant, signaling thes contents are as follows shown in the table:
| Transport block length indication (6 bit) | HARQ process number (2 bit) | Re-transmission sequence number (2 bit) |
Wherein transport block length indication (E-TFCI) is used to indicate E-DCH transport block length and modulation system, in the TD-SCDMA system, transport block length is according to the customization of the E-DCH physical layer ability classification of UE, identical E-TFCI means different values concerning the UE of different ability classifications, with the non-scheduling service among the E-DCH is example, under the situation of distributing 1 time interval resource, if UE indicates E-TFCI=63 in E-UCCH, for E-DCH physical layer ability classification 1 UE, mean that transport block length is 1346, use QPSK (Quadrature Phase ShiftKeying, Quadrature Phase Shift Keying) modulation system; And be 3 UE for the ability classification, mean that transport block length is 2720, use 16QAM (16 Quadrature Amplitude Modulation, 16 quadrature amplitude modulation) mode (can with reference to 3GPP agreement 25.321).And according to existing RRC signaling process, UE is that (being the step 103 of Fig. 1) sends to RNC with the wireless access capability information (wherein comprising E-DCH ability classification and HSDPA ability classification) that goes up oneself in the RRC connection setup complete message.And Node B just knows the real ability classification of UE after reception RNC is to the radio link reconfiguration message of this UE.For the transmission of RRC connection setup complete message itself, can cause network side not know the ability classification of UE and carry out wrong decoding.
Such problem also can appear among the HSDPA.3GPP strengthens CELL_FACH (sub-district _ forward access channel) state, introduced the HSDPA technology, like this, support the UE of HSDPA initiating on the HSDPA channel, receiving downlink signaling behind the RRC connection request, comprise that RRC connects to set up message (step 102 among Fig. 1).In the TD-SCDMA system, when carrying out the HSDPA transmission, Node B need pass through HS-SCCH (High-Speed Shared Control Channel) Channel Transmission descending control signaling, and signaling thes contents are as follows shown in the table:
| Code channel (8 bit) | Time slot (5 bit) | Modulation system (1 bit) | Transport block length indication (6 bit) | HARQ process number (3 bit) | Redundancy versions (3 bit) | New data indication (1 bit) | Sequence number (3 bit) |
Wherein, code channel and gap information indication UE is about to HS-PDSCH (high-speed downstream Physical Shared Channel) channel resource of reception; Modulation system and transport block length indication transformat.After receiving HS-SCCH, after the time, UE receives data on the HS-PDSCH of appointment channel in predetermined timing.The code channel of the last indication of HS-SCCH, time interval resource all should satisfy the physical layer ability of UE, and the corresponding transport block length value of transport block length indication is also because of the ability of UE different (can with reference to 3GPP agreement 25.321) in addition.Node B can not cause invalid scheduling because knowing the ability of UE.
Above problem also can occur in the WCDMA system, after particularly WCDMA has introduced the CELL_FACH enhancement techniques, some support the UE of HSDPA can't support because the ability classification crosses low CELL_FACH strengthen in the retransmission mechanism of regulation.If network side can be known the ability of UE in advance, the UE lower for the ability classification can select other channels, transmits signaling as FACH (forward access channel) for UE.
In sum, use HSPA command transmitting radio bearer and not only can improve the signaling propagation delay time greatly, improve user experience, and can improve resource utilization by using HSPA shared channel technology.But, for the initialization signaling transmit stage, if signaling is transmitted on HSPA, owing to network side is not known the ability classification of UE and the situation of mistake scheduling or invalid decoding occurred, and the initialization signaling transmission directly affects the satisfaction of user to network, thereby need solve existing problem as early as possible, optimize the signaling transmission.
