Problems solved by technology

Especially when some abnormal situations occur (for example, the target side accepts the request from the source side and modifies the mobility parameters of the target side, but the source side abandons the negotiation process because the timer for waiting for the confirmation message from the target side expires, Therefore, the mobility parameters of the source itself are not modified), and there is a high possibility that the mobility parameters of the source and the target side will not match

Embodiment 1

[0094] Such as figure 1 As shown, the source eNB can initiate a mobility parameter matching detection process to the target eNB when needed (such as before or after the mobility parameter modification negotiation process, or when a mobility problem is found) or periodically, the process includes The following steps:

[0095] Step 101, the source eNB sends a mobility parameter modification request message to the target eNB, the request message carries the cause value "mobility parameter matching detection", and can also carry the current value of the mobility parameter of the source cell, and / or the current value of the source cell Permissible range of mobility parameters;

[0096] Step 102, after the target eNB receives the mobility parameter modification request message from the source eNB, if the cause value carried in the request message is "mobility parameter matching detection", it returns a mobility parameter modification confirmation message, and the confirmation messa...

Embodiment 2

[0100] Such as figure 2 As shown, the source eNB can initiate a mobility parameter matching detection process to the target eNB when needed (such as before or after the mobility parameter modification negotiation process, or when a mobility problem is found) or periodically, the process includes The following steps:

[0101] Step 201, the source eNB sends a mobility parameter modification request message to the target eNB, and the request message carries the cause value "mobility parameter matching detection", the current value of the mobility parameter of the source cell, and may also carry the mobility parameter of the source cell the allowable range;

[0102] Step 202, after the target eNB receives the mobility parameter modification request message from the source eNB, if the cause value carried in the request message is "mobility parameter matching detection", then according to the current mobility parameter of the source cell carried in the request message value, and ...

Embodiment 3

[0106] Such as figure 2 As shown, the source eNB can initiate the mobility parameter matching detection process to the target eNB when needed (such as before or after the mobility parameter modification negotiation process, or when a mobility problem is found) or periodically.

[0107] The mobility parameter matching detection process in this embodiment is basically the same as that in Embodiment 2, the difference is that:

[0108] In step 202, when the target eNB returns the mobility parameter modification confirmation message, if a problem is found in the matching detection, the returned confirmation message carries the cause value "mobility parameter matching detection failed", and can also carry the target cell. The current value of the mobility parameter, and / or the allowable range of the mobility parameter of the target cell; if no problem is found in the matching test, the returned confirmation message does not contain the reason value "mobility parameter matching test...

Abstract

The invention discloses a mobility parameter matching detection method and system, the method comprising: a source base station or a target base station according to the current values ​​of the mobility parameters of the source cell and the target cell, or the mobility parameters of the source cell and the target cell The current value of the current value plus the value to be confirmed after the incremental value to be modified, by judging whether the overlapping area of ​​the mobility boundary between the source cell and the target cell satisfies the matching condition, the source cell and the target cell are detected Whether the mobility parameters between cells match. By adopting the technical scheme of the present invention, it is possible to detect the matching of mobility parameters of two adjacent cells between eNBs in the LTE / LTE-A system, enhance the correctness of the existing mobility parameter modification negotiation process, and avoid abnormalities as much as possible. The mismatch of mobility parameters between neighbors caused by the situation.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a method and system for detecting the matching of mobility parameters. Background technique [0002] The Long Term Evolution (LTE for short) network of the third-generation mobile communication consists of an Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN for short) and an Evolved Packet Core (EPC for short) network. E-UTRAN includes a collection of evolved base stations (EvolvedNodeB, referred to as eNB), and EPC includes Mobile Management Entity (Mobile Management Entity, referred to as MME) and Serving Gateway (Serving Gateway, referred to as S-GW), etc., and the network architecture is flat. The eNB and MME / S-GW are connected through the S1 interface, and the eNBs can be connected through the X2 interface. S1 and X2 are logical interfaces. One MME / S-GW can manage one or more eNB...
