According to the technical scheme of the invention, the CRNC Communication Context ID generated by RNC is directly obtained according to the corresponding relation between the UE marker and CRNC Communication Context ID at the Node B, thereby knowing the wireless link setup information corresponding to the UE marker, namely realizing continuous tracking on the appointed UE information.
Description
Technical field
The present invention relates to a kind of on the NodeB of TD SCDMA or WCDMA the method for the signaling of Continuous Tracking designated user (UE).
Background technology
At present,, often need specify physical layer information and the signaling process of UE, comprise UE calling procedure and handoff procedure at the NodeB all-the-way tracking in occasions such as network analysis, test and fault location.
Call out (signaling bear is in dedicated channel) roughly flow process (complete call signalling flow as shown in Figure 1, the interacting message that relates to is a lot, the signaling that Fig. 1 draws and is correlated with in the present invention, other incoherent signalings are summarized with other signalings, be exactly professional transmission behind the Signalling exchange, also do not have direct relation with the present invention):
1, UE initiates RRC (Radio Resource Control) and sets up request, carry UE in the message and indicate IMSI (International Mobile Subscriber Identity) or TMSI (Temporary Mobile SubscriberIdentity) or P-TMSI (Packet Temporary Mobile Subscriber Identity), send to RNC by uplink common channel.
2, RNC (radio network controller) sets up the RRC connection, this connection can be based upon on the common signal channel and also can be based upon on the dedicated channel, be based upon on the dedicated channel if RRC connects, then RNC sends out Radio Link to NodeB and sets up request, sets up the physical carrier of eating dishes without rice or wine.
3, NodeB returns the RNC Radio Link and sets up response.
4, RNC sends RRC connection foundation to UE, carry U-RNTI (UTRAN Radio NetworkTemporary Identifier) and C-RNTI (Cell Radio Network Temporary Identifier) in the message, and will notify the next message of UE in dedicated channel, to report still to report in the common channel.
5, UE sends signalings such as RRC connection setup complete message and initial direct-sending on allocated channel.
If 6 UE need transport service, RNC can set up physical carrier according to type of service, just sends Radio Link to NodeB and sets up request message, is based upon on the dedicated channel if RRC connects, and then sends wireless link reconfigured request message to NodeB.(whether reprovision takes place with the concrete business that UE initiates very big relation is arranged, as being the words that a position is upgraded, just can reprovision, if short message, also not can, if normally make a phone call, perhaps download the words of thing, need the data of transmission a lot of this time, and this moment, reprovision will take place).
Can specify IMSI, the TMSI of UE and the mode of P-TMSI by trace tool, resolve the Frame of uplink common channel, can trace into the RRC connection of specifying UE and set up request message at NodeB.
If the RRC of RNC connects and to be based upon on the dedicated channel, because set up the beacon information that does not have UE in the message at Radio Link, then NodeB can't judge that corresponding which wireless links of UE of appointment sets up message, therefore can't continue to follow the tracks of.
If connecting, the RRC of RNC is based upon on the common signal channel, (same as in figure 1 as shown in Figure 2, Fig. 2 also just draws and relative section of the present invention), NodeB can be by resolving the Frame on the common down channel, obtain the RRC connection corresponding and set up message, carry U-RNTI and C-RNTI information in the message thereby obtain with specifying UE.By these two signs, also can tell other signalings of specifying UE from common signal channel.When not excessive UE carried out professional transmission, NodeB can't judge that still corresponding which wireless links of the UE of appointment sets up message, therefore can't continue to follow the tracks of.
The roughly flow process of switching is as shown in Figure 3:
1, UE switches in business procedure, and there has been corresponding dedicated channel in sub-district 2, UE prepare from the sub-district 2 change to 1, two sub-district, sub-district can also can be at different NodeB at same NodeB.
2, RNC sends out Radio Link to the NodeB at 1 place, sub-district and sets up request, and NodeB responds the Radio Link response, sets up the dedicated channel of UE on sub-district 1.
3, RNC is on the dedicated channel of the UE of sub-district 2 correspondence, to UE stimulating food reason channel reconfiguration message.The dedicated channel of notice UE 1 correspondence in the sub-district.
4, UE returns physical channel and reshuffles success message, and message bearing is on the dedicated channel that RNC sets up for this UE in sub-district 1.
5, RNC sends out the Radio Link removal request to the NodeB at 2 places, sub-district, and NodeB responds the Radio Link response, the dedicated channel of deletion UE correspondence on sub-district 2.
There are same situation in the handoff procedure of UE and access procedure, therefore all can't realize following the tracks of the Continuous Tracking of specifying UE.
Because each NodeB is distributed in different places, general all is to carry out Long-distance Control by NodeB with being connected of RNC, and in the network planning, distribute too much bandwidth can for NodeB and being connected of RNC, therefore also can not be by all following the tracks of the mode of follow-up screening, obtain the information of specifying UE, therefore can't realize following the tracks of the UE of appointment.
