Method and system for updating configuration, evolved node B (eNB) and mobility management entities (MME)

Abstract

The invention provides a method and a system for updating configuration, an evolved node B (eNB) and mobility management entities (MME). The method comprises the following steps of: after S1 port configuration information of the eNB is updated, transmitting the updated S1 port configuration information to each adjacent MME respectively; if the reply of each MME is successful response, informing each MME of utilizing the received updated S1 port configuration information to update respective S1 port configuration information by the eNB; and if the reply of each MME is not successful response, informing each MME of discarding the received updated S1 port configuration information. In the method, the eNB does not allow all the adjacent MME to update the S1 port configuration information as long as one MME cannot update the S1 port configuration information, so that the problem of inconsistent S1 port configuration information of the same eNB on different adjacent MME caused by that some (one or more than one) adjacent MME cannot accept the configuration update information of the eNB successfully is solved, the consistency of the S1 port configuration information of the eNB on each adjacent MME is guaranteed, and basic guarantee is provided for the correctness of the subsequent flow of the S1 port.

Description

technical field [0001] The present invention relates to long-term evolution (LTE, Long Term Evolution) technology, in particular to a method and system for updating S1 port configuration of an evolving Node B (eNB, eNodeB) in an LTE system, as well as an eNB and an MME. Background technique [0002] In the LTE system, after the eNB and each neighboring Mobility Management Entity (MME, Mobility Management Entity) have respectively established S1 interfaces, if the configuration information of the S1 interface of the eNB changes, the eNB will send a report to each adjacent MME that has established the S1 interface. Send eNB configuration update (ENBCONFIGURATION UPDATE) message. [0003] figure 1 The flow chart of the method for configuring and updating the S1 interface of the existing eNB, taking eNB1 with two adjacent MMEs (MME1 and MME2) as an example, such as figure 1 shown, including the following steps: [0004] Step 100: eNB1 sends an S1 setup request (S1 SETUP REQUE...

AI Technical Summary

Problems solved by technology

In this way, for the same eNB, adjacent MMEs have different S1 port configuration information, which leads to the inconsistency of the S1 port configuration information of the same eNB in ​​different adjacent MMEs, which affects the correct execution of other processes of the subsequent S1 port
