Locating an access control failure:


lCONNECTPLMN configuration problem:


pAfter Gb or Iu interface failure is excluded, some subscribers still cannot attach the GPRS network, the SGSN can receive the "Attach Request" message, but the SGSN quickly rejects the request. The rejected cause value is "GPRS Service not Allowed“.


pCheck whether these subscribers have common features. If they all belong to a certain roaming PLMN, you can find out if the SGSN configures its subscription PLMN to connect PLMN by running the LST CONNECTPLMN command.


pIf connect PLMN is not configured, you can add the configuration by running ADD CONNECTPLMN command to recover failure.
