Method for reducing failure of configuration update initiated by eNB and eNB

A method for reducing failure of configuration update initiated by an evolved Node B (eNB), comprising the steps:

• the eNB storing Public Land Mobile Network (PLMN) identities of a Mobility Management Entity (MME) to which the eNB connects;
• after a configuration of the eNB is updated, the eNB comparing PLMN identities of the eNB with the PLMN identities of the MME stored in the eNB;
• when the eNB determines that all the PLMN identities of the eNB are completely consistent with all the PLMN identities of the MME stored in the eNB, the eNB sending a configuration update request to the MME;
• when the eNB determines that at least one PLMN identity of the eNB is not consistent with any one of the PLMN identities of the MME stored in the eNB, the eNB sending a configuration update request to the MME and alarming;
• when the eNB determines that all the PLMN identities of the eNB are completely inconsistent with all the PLMN identities of the MME stored in the eNB, the eNB alarming;
• wherein, the step of the eNB alarming is specifically that the eNB displaying alarm information, and the alarm information prompts parameters which are not consistent in the PLMN identities of the eNB and in the PLMN identities of the MME stored in the eNB.
