Embodiment 1
[0160] Embodiment 1: As shown in step 2 in Figure 2, the RNC allocates radio layer resources and transport layer resources for the RRC connection. During the allocation process, it is found that the spreading factor that the RRC needs to use is 128, but the minimum available spreading factor in the current cell is If the value is 256, the RRC connection cannot be successfully established due to the lack of idle code resources. Therefore, according to the description of the RRC connection establishment failure protocol structure in Table 1, the following information needs to be recorded:
[0161] 1) The initial ID of the user, directly from the RRC connection establishment request, can be IMSI, TMSI, P-TMSI or IMEI;
[0162] 2) The reason for RRC establishment comes from the RRC connection establishment request, such as the calling session service;
[0163] 3) RRC establishment time, just take the current time;
[0164] 4) The current cell ID, and the RSCP or Ec / No of the cel...
Embodiment 2
[0169] Embodiment 2: As in step 3 in FIG. 2, NODEB does not return RADIO LINK SETUP RESPONSE within the waiting time of RNC, and RNC cannot perform subsequent procedures, resulting in failure of the RRC connection establishment procedure. Therefore, according to the description of the RRC connection establishment failure protocol structure in Table 1, the following information needs to be recorded:
[0170] 1) 2) 3) 4) 5) 6) as described in Example 1;
[0171] 7) The reason for setting failure can be known from the table. This reason should be attributed to IUB interface error - RL establishment failure - RL establishment timer timeout.
[0172] 8) Same as step 8) in (1).
Embodiment 3
[0174] When the calling user moves to a weak cell coverage area, a soft handover may be triggered, and the RRC connection establishment may fail due to the limited resources of the target cell, but we can help us optimize the network by outputting the relevant information of these failures. , so that users can switch flexibly.
[0175] For example, when a user in a certain cell has difficulty accessing, the call fails. At this time, you can search for the CHR record of the failure to establish the RRC connection. For example, a user's record is as follows:
[0176] Table 27: User records
