Abstract

The invention provides a method for continuously tracking a designated user in NodeB. The method comprises the following steps of: 1, modifying an Iub port protocol of an existing wireless link establishment message, and adding a UE (User Equipment) label in an extension field; 2, determining a tracked UE label by a tracking tool; 3, transmitting the UE label to a designated NodeB by the tracking tool, and starting tracking; and 4, analyzing a data frame of a public channel by the NodeB, and determining whether the data frame is related to the designated UE through the UE label, and transmitting the data frame to the tracking tool if the data frame is related to the designated UE. According to the method, a wireless link establishment message corresponding to the designated UE label can be known, and continuous tracking to the designated UE message can be realized.

Description

Method at NodeB Continuous Tracking designated user

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, in occasions such as network analysis, test and fault location, often need specify physical layer information and the signaling process of UE at the NodeB all-the-way tracking, comprise UE calling procedure and handoff procedure.

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 Subscriber Identity) 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 Network Temporary 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 at 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 the trace tool at NodeB, resolve the Frame of uplink common channel, can trace into the RRC connection of specifying UE and set up request message.

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 with specifying UE and set up message, carry U-RNTI and C-RNTI information in the message thereby obtain.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 residential quarter 2, UE prepare from the residential quarter 2 change to 1, two residential quarter, residential quarter can also can be at different NodeB at same NodeB.

2, the NodeB at RNC 1 place to the residential quarter sends out the Radio Link request of setting up, and NodeB responds the Radio Link response, 1 dedicated channel of setting up UE in the residential quarter.

3, RNC is on the dedicated channel of the UE of residential quarter 2 correspondence, to UE stimulating food reason channel reconfiguration message.The dedicated channel of notice UE 1 correspondence in the residential quarter.

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 residential quarter 1.

5, the NodeB at RNC 2 places to the residential quarter sends out the Radio Link removal request, and NodeB responds the Radio Link response, the dedicated channel of deletion UE correspondence on residential quarter 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.

Summary of the invention

Main purpose of the present invention provides a kind of method at NodeB Continuous Tracking designated user, and at realizing following the tracks of the problem of specifying UE in the prior art, proposition can be followed the tracks of the method for specifying UE.

The technical solution adopted for the present invention to solve the technical problems is:

Implement technical scheme of the present invention, has following beneficial effect: the method at NodeB Continuous Tracking designated user provided by the invention, can directly obtain the communication context sign CRNC Communication Context ID that RNC will generate according to known UE sign and the corresponding relation between the CRNCCommunication Context ID at NodeB, thereby can know that the Radio Link corresponding with specifying the UE mark set up message, also just can realize the Continuous Tracking to appointment UE message.
