[0012] 2. The coverage area of ​​a macro base station (macro eNB) contains a large number of micro base stations (micro eNBs), and the X2 establishment request between the micro eNB and the macro eNB will consume a large amount of physical resources of the macro eNB, so in this case IRPMananger does not allow micro eNB to establish x2 interface with macroeNB
[0013] 3. At the border of administrative regions, such as eNBs near provincial borders, IRPManager does not allow eNBs at the borders to establish X2 interfaces with eNBs in other provinces
[0015] When there is no x2 interface between eNBs, the existing technology cannot realize the acquisition of neighbor cell load information

Embodiment 1

[0052] Embodiment 1: The first eNB and the second eNB belong to the same MME pool.

[0053] The process of obtaining neighbor cell load information is as follows: figure 2 shown, including the following steps:

[0054] Step 201: The first eNB sends a load request message (eNBResource Status Request) to the MME through the S1 interface, which includes the base station identifier, load type, reporting period, request measurement identifier, etc. of the second eNB.

[0055] Step 202: MME parses the message after receiving the load request message, and judges that the second eNB belongs to the current MME pool, then sends a load request transfer message (MMEResource Status Request Transfer) to the second eNB through the S1 interface, which includes the first eNB base station ID, load type, reporting period, and request measurement ID.

[0056] Step 203: The second eNB receives the load request transfer message sent by the MME, obtains the corresponding load information accordin...

Embodiment 2

[0064] Embodiment 2: the first eNB and the second eNB belong to different MME pools, the first eNB belongs to the first MME pool, and the second eNB belongs to the second MME pool.

[0065] The process of obtaining neighbor cell load information is as follows: Figure 4 shown, including the following steps:

[0066] Step 401: The first eNB sends a load request message (eNB Resource Status Request) to any MME in the first MME pool through the S1 interface, which contains the base station identifier, load type, reporting period, request measurement identifier, etc. of the second eNB .

[0067] Step 402: After receiving the load request message, the MME parses the message, determines that the second eNB does not belong to the first MME pool, then determines that the MME pool to which the second eNB belongs is the second MME pool, and sends a request to the second MME pool Any MME forwards the load request message.

[0068] Step 403: The MME in the second MME pool that receives...

Abstract

The invention discloses a method for acquiring neighboring cell load information from an LTE system. The method comprises the following steps that: a first base station sends a load request message which carries a base station identifier of a second base station to a mobile management entity (MME) through an S1 interface; the MME resolves the load request message and sends a load request retransmission message which carries the base station identifier of the first base station to the second base station through the S1 interface; the second base station acquires the load information of a cell which is controlled by the second base station and sends a load response message which carries the base station identifier of the first base station and the load message to the MME through the S1 interface; and the MME sends the load response retransmission message which carries the base station identifier of the second base station and the load message to the first base station through the S1 interface. The invention also discloses a system and the mobile management entity which can apply the method. The invention provides the scheme of realizing acquisition of the neighboring cell load message by using the S1 interface, so the reliability of the system is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for acquiring load information of adjacent cells in a Long Term Evolution (LTE) system. Background technique [0002] The connection relationship of network elements in the Evolved-Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) in the LTE system is as follows figure 1 shown. E-UTRAN includes a number of base stations (eNBs) 102 that provide the user plane (packet data control protocol / radio link control / medium access control layer / physical layer) and control plane (radio resource control (RRC)) of E-UTRA. protocol, terminated at the user equipment (UE). The eNBs 102 can be connected to each other through the X2 interface. The eNB 102 is connected to an evolved packet core (Evolved Packet Core, EPC) 101 through an S1 interface. The EPC may be a mobile management entity (Mobile Management En...
