After channel request message, MS is at 30 radio-frequency channel that signal is the strongest (Radio Frequency, RF) search, if do not find proper cell, MS will continue to detect the signal strength signal intensity of all RF channels, and search cell is selected parameters C 1＞0 and Broadcast Control Channel (the Broadcast Control Channel of the access that is not under an embargo, BCCH), after finding qualified channel, MS selects the sub-district at this channel place, and do not need to consider that (Public Land Mobile Network PLMN) discerns the public land mobile telephone network.
When disasters such as natural calamity take place,, can adopt base station, the high-altitude business that continues usually because the ground base station large tracts of land is impaired; and the high-altitude base station number is less, generally is positioned at more than the hundreds of rice of ground, and adopts omnidirectional antenna; provide omnibearing covering to ground, covering radius will reach tens kilometers.At this moment, a large amount of MS can occur and attempt inserting base station, same high-altitude, insert global system for mobile communications (Global System for Mobile communication by this base station, high-altitude application, GSM), the user that Home Network is not only arranged among these MS, the user who also comprises other nets not only comprises in the user of Home Network and can insert the user that GSM roams, and also comprises not allowing the user that roams.Like this, Separate Dedicated Control Channel (Separate Dedicated Control Channel, SDCCH) channel congestion, the phenomenon that MS can't insert will appear.The idiographic flow of MS access base station, high-altitude is as shown in Figure 1 in the prior art:
Step 101, MS initiate channel request message Channel Request on RACH;
The channel request message that step 102, BTS are initiated MS be forwarded to base station controller (Base Station Center, BSC);
Step 103, BSC issue channel to BTS and activate message Channel Activation;
Step 104, BTS activate to the BSC feedback channel and reply Channel Activation Ack;
Step 105, BSC issue the Immediate of allocated channel instruction immediately Assignment Command to BTS;
(Access Grant Channel AGCH) distributes SDCCH for MS by allowing access channel immediately for step 106, BTS;
Step 107, MS initiate connection management (Connection Management, CM) service request on the SDCCH that distributes;
Step 108, BTS are forwarded to base station controller with the CM service request that MS initiates;
Step 109, BSC with the CM service request be forwarded to mobile switching centre (Mobile Switching Control, MSC);
Step 110, BTS by SDCCH to MS feedback unnumbered acknowledge frame (Unnumbered Acknowledgement, UA);
Step 111, MSC send authentication request Authentication Request to BSC;
Step 112, BSC send authentication request by SDCCH to MS;
Step 113, MS feed back Authentication Response Authentication Response by SDCCH to BSC;
Step 114, BSC feed back to MSC with Authentication Response;
Step 115, MSC issue encryption mode order Ciphering Mode Command to BSC;
Step 116, BSC are transmitted to BTS with the encryption mode order;
Step 117, BTS by SDCCH to the encryption mode order is transmitted to MS;
Step 118, MS send encryption mode end Ciphering Mode Complete by SDCCH to BSC;
Step 119, BSC are transmitted to MSC with the encryption mode end;
Step 120, MSC issue temporarily moved subscriber instruction (Temporary Mobile Station Identity, TMSI) heavy distribution instruction to BSC;
Step 121, BSC transmit the heavy distribution instruction of TMSI by SDCCH to MS;
Step 122, MS heavily distribute end by SDCCH to BSC notice TMSI;
Step 123, BSC heavily distribute end to MSC notice TMSI;
Step 124, set up successfully.
If the MS failed authentication, network can send failed authentication message to MS by BTS, and discharges the SDCCH channel that has distributed, and this MS will no longer initiate to insert request within a certain period of time, still, after T3122 is overtime, still can initiate to insert request once more.
When disaster takes place, a large amount of MS can initiate to insert request in base station, same high-altitude, when existing SDCCH idle, this base station, high-altitude is SDCCH of each MS distribution, and his network users or Home Network forbid that the user who roams can be rejected when authentication, after T3122 is overtime, unaccepted user can continue to initiate request again, and SDCCH congested and Traffic Channel (Traffic Channel, TCH) Kong Xian situation appear in this trial repeatedly easily, may cause signal to connect, increase the burden of network.
Further,, need to take ABIS and A mouth resource in this process, and need the processing time, increased the burden of network equally from distributing the access request of SDCCH to MS refusal MS behind the MSC failed authentication.
