Abstract
The present invention discloses a method for sending a downlink response message at a random access stage. In the prior art, because UE (User Equipment) can hardly receive the access response message returned by a UTRAN (UMTS Terrestrial Radio Access Network), the access of the UE fails, the present invention can resolve the problem. The method includes two steps; firstly, the user equipment sends an access request message to a radio network controller, the message contains the measuring report with the pilot frequency intensity of a local subdistrict and other subdistricts; secondly, according to the measuring report, when the radio network controller determines that the pilot frequency intensity of the local subdistrict is lower than a threshold value, the other subdistricts with the pilot frequency intensity higher than the threshold value are selected, an access response message is issued to the user equipment via the local subdistrict and the other subdistricts. The present invention also discloses the user equipment, the radio network controller and a communication system.
Description
Technical field
The present invention relates to communication technical field, relate in particular to the descending response message transmission method and the system of accidental access stage.
Background technology
Consult shown in Figure 1A, in present TD-SCDMA system, the handling process when user equipment (UE) carries out Radio Resource control connection RRC is as follows:
Step 100, user equipment (UE) send wireless resource control connection request (RRC Connection Request) message at the RACH of sub-district A channel to UTRAN (UMTSTerrestrial Radio Access Network, UMTS Terrestrial radio access network).
Step 101, UTRAN send the Radio Resource control connection at the FACH of sub-district A channel to UE and set up (RRC Connection Setup) message.
After step 102, UE receive and untie described Radio Resource control connection and set up message, send the Radio Resource control connection to UTRAN and set up and finish (RRC Connection Setup Complete) message, finish access process.
Consult shown in Figure 1B, if in flow process shown in Figure 1A, UE does not receive described Radio Resource control connection and sets up message, so after T300 is overtime, resend wireless resource control connection request message, up to having sent N300 time (with reference to descriptions such as 3GPP TS25.331,3GPP TS25.931).
Similar with above-mentioned Radio Resource control connection RRC process, after UE initiates cell update request message (CELL Update), if when not receiving the cell update response message (CELL Update Confirm) that network side issues at the FACH channel, after T302 is overtime, resend cell update request message CELL Update, up to having sent N302 time (with reference to descriptions such as 3GPP TS25.331,3GPP TS25.931).
Further, in the TD-SCDMA system, finish message Complete for up wireless resource control connection request message Request, the foundation of Radio Resource control connection, because there is the gain of smart antenna in recipient Node B in the algorithm in demodulation, perhaps because Node B highly sensitive, therefore up reception is good; And descending Radio Resource control connection is set up message Setup owing to being not suitable for adopting smart antenna or adopting back gain not enough (asking Request and set up between two message of Setup to have hundreds of milliseconds delay), perhaps because the UE poor sensitivity, therefore to receive the probability of Setup message lower for UE, has an access bottleneck.Improve success rate though UE after T300 is overtime, adopts repeatedly (N300) to send Request, will cause the user to insert the increase of delaying like this.
Cell update CELL Update process is similar with wireless resource control connection request RRC ConnectionRequest process, also exists CELL Update reception good, and CELL Update Confirm receives bad problem.
