Problems solved by technology

[0007] The present invention is proposed to solve the problem in the related art that the measurement request sent by the source eNB only carries a neighboring cell associated with the geographic location of the serving cell. Therefore, the main purpose of the present invention is to provide a load information interaction method and system , to solve the above problem

example 1

[0044] Example 1: When the neighbor relationship of the serving cell of the source eNB changes or the status of the neighbor cell changes, if the serving cell adds the neighbor cell of the target eNB associated with the geographic location or the neighbor cell status of the target eNB associated with the geographic location is available , that is, for the same target eNB, the measurement object in the original measurement request container of the source eNB is a subset of the measurement object in the current measurement request container, stop the existing measurement request first, and then organize a new measurement request and initiate New measurement request; if the serving cell reduces the neighbor cell of the target eNB associated with the geographic location or the neighbor cell status of the target eNB associated with the geographic location is unavailable, that is, for the same target eNB, the current measurement object of the source eNB is the original Subsets of mea...

example 2

[0045] Example 2: When a serving cell of the source eNB is unavailable, if the source eNB and the target eNB still have an available geographical location-associated neighbor cell, then do not update; otherwise, stop the related measurement request.

[0046] In addition, when the X2 interface is interrupted, the common measurement module of the source eNB stops all measurement requests related to the X2 interface.

[0047] Preferably, after the source eNB sends the first measurement request, the method further includes: the target eNB receives the first measurement request; the target eNB starts a periodic timer according to the load information update period carried in the first measurement request; Every time the permanent timer expires, the target eNB sends a load information update message to the source eNB, wherein the load information update message carries the load information of the neighboring cell carried in the first measurement request. In this preferred embodiment...

Embodiment 1

[0053] figure 2 It is a flow chart of organizing measurement requests in groups according to preferred embodiment 1 of the present invention, such as figure 2 As shown, the following steps S202 to S206 are included.

[0054] In step S202, the public measurement module obtains the neighboring cell information of all neighboring cells corresponding to each serving cell of the eNB from the neighboring cell module.

[0055] Step S204, the public measurement module traverses each neighboring cell of each serving cell, and judges whether the neighboring cell satisfies the requirements associated with geographic location (same coverage or inclusion).

[0056] Step S206, if the neighbor cell and the serving cell meet the requirement of geographical location association (same coverage or inclusion), put the neighbor cell into the corresponding measurement request container according to MCC, MNC and eNodeId. If the adjacent cell already exists in the measurement request container, i...

Abstract

The invention provides a load information interactive method and system; the method comprises the steps as follows: a source eNB (Base Station) is used for obtaining neighbor cell information of all neighbor cells of each service cell in a local eNB; the source eNB is used for generating a first measuring request according to the neighbor cell information, wherein the first measuring request carries neighbor cells of all neighbor cells associated with the geographical position of the service cell; and the source eNB is used for transmitting the first measuring request. According to the invention, the interactive information can be reduced, so that the load of an X2 interface is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a load information interaction method and system. Background technique [0002] Long-Term Evolution (LTE for short) introduced Orthogonal Frequency Division Multiple Access (OFDMA for short) technology and Multiple Input Multiple Output (MIMO for short) technology, which greatly improved Cell throughput. However, the air interface resources of the cell are still limited. With the increase of the number of users and services, the load of the cell will gradually increase, and the increase of the cell load will affect the performance of user services. If the load of the cell cannot be reduced effectively in time, when the load of the system increases to the warning line of the system, the performance of the system will deteriorate sharply and even cause the system to collapse. [0003] 3GPP has proposed a variety of solutions, and load balancing is one of the hot technologies cur...
