Embodiment 1
[0134] Example 1: As in figure 2 In step 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 RRC needs to use is 128, but the smallest available spreading factor in the current cell is 256, resulting in no idle code resources The RRC connection cannot be established successfully. Therefore, according to the description of the RRC connection establishment failure protocol structure in Table 1, the following information needs to be recorded:
[0135] 1) The user's initial ID is directly derived from the RRC connection establishment request, which can be IMSI, TMSI, P-TMSI or IMEI;
[0136] 2) The reason for RRC establishment comes from the RRC connection establishment request, such as calling session service;
[0137] 3) RRC establishment time, just take the current time;
[0138] 4) The current cell ID, and the RSCP or Ec / No of the cell reported by the RRC connecti...
Embodiment 2
[0143] Example 2: As in figure 2 In step 3, NODEB did not return RADIO LINK SETUP RESPONSE within the waiting time of RNC, and RNC was unable to proceed with the subsequent process, which resulted in the failure of the RRC connection establishment process. Therefore, according to the description of the RRC connection establishment failure protocol structure in Table 1, the following information needs to be recorded:
[0144] 1) 2) 3) 4) 5) 6) Same as described in Example 1;
[0145] 7) Setting the reason for failure, you can know from the table, this reason should be attributed to IUB interface error-RL establishment failure-RL establishment timer timeout.
[0146] 8) Same as step 8) in (1).
Embodiment 3
[0148] When the calling user moves to an area with weak cell coverage, a soft handover may be triggered. Then the RRC connection establishment failure may occur due to the limited resources of the target cell, but we can help us optimize the network by outputting relevant information about these failures. , So that users can switch flexibly.
[0149] For example, when users in a certain cell are difficult to access, the call fails. At this time, you can search for the CHR record of the failed RRC connection establishment. For example, the record of a user is as follows:
[0150] User ID
P-TMSI: C103ACF4
MCC: 460
MNC: 07
LAC: 2514
RAC: 00
