Description

Cell load state detection method and communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for detecting a cell load state and a communications device.

Background

The rapid popularization of tablet computers and smart phones drives the rapid expansion of the total mobile traffic, and the rapidly increasing traffic makes operators urgently need to detect cell congestion and perform corresponding cell congestion management.

The User Plane Congestion Management (abbreviated as UPCON) protocol refers to two different Congestion concepts of User-oriented Congestion and resource-oriented Congestion, but the specific meaning and how to calculate the cell load state are not specified, and the basic idea is to solve the User Congestion feeling through resource Congestion control.

The resource type cell load state is to judge the cell load state based on the utilization rate of the related resources in the cell, and when the cell resource utilization rate reaches a specified threshold value, the cell load state is judged to be normal, congested or overloaded, however, the user experience cannot be directly reflected based on the resource type cell load state. Referring to fig. 1, a schematic diagram of statistical distribution of bandwidth occupation of each user in a cell in a period in the prior art is shown in fig. 1, where resources of the cell are mainly occupied by the user 1, bandwidth requirements of all users are fully met at this time, and experience is good, but since a resource utilization rate is 95%, and the resource utilization rate exceeds an overload threshold, the cell enters an overload state, and therefore, a cell load state based on the resource utilization rate cannot effectively reflect user experience.

The experienced cell load state is judged based on the experience of the user, and from the perspective of a pipeline, the current user experience is mainly embodied by the actual speed of the user, and the method comprises the following steps: counting the average value of the actual rates of users in a cell in a counting period, wherein the average value of the actual rates is equal to the total flow of the cell divided by the number of activated users in the cell in the counting period, if the average value is smaller than a preset overload threshold, determining that the load state of the cell is overload, if the average value is larger than or equal to the preset overload threshold and smaller than a preset congestion threshold, determining that the load state of the cell is congestion, and if the average value is larger than or equal to the preset congestion threshold, determining that the load state of the cell is normal. Since the average value of the actual rates of the users in the cell is determined by the total cell flow and the number of activated users in the cell, and the total cell flow is influenced by the service requirements of the actual users, if the users are only performing the Instant Messaging (IM) service with small flow, the actual rates of the users are always small, regardless of the state of the cell, the more the number of users, the smaller the average value of the actual rates of the users is, when most of the users are only performing the small flow service online, the smaller the average value of the actual rates of the users in the cell is, and the cell load state can be determined to be overload, but the actual experience of the users is good at this time, so the determination of the cell load state in the prior art is not accurate enough.

Specifically, the base station may determine the load status of the cell according to the available rate of each of the multiple reference user equipments and the service rate of each of the multiple reference user equipments in any one of the following manners:

1) the base station determines a restricted reference user equipment of the multiple reference user equipments, specifically: determining the reference user equipment as limited reference user equipment when the service rate of the reference user equipment is the actual rate of the reference user equipment in a first time interval and the available rate of the reference user equipment comprises the available rate which is greater than or equal to the actual rate of the reference user equipment; or, when the service rate of the reference user equipment is the subscription rate of the reference user equipment and the available rate of the reference user equipment includes an available rate greater than or equal to the subscription rate of the reference user equipment, determining that the reference user equipment is a limited reference user equipment.

It should be noted that, in order to facilitate the determination of the unrestricted reference user equipment, the maximum of the available rates of the reference user equipment may be used for comparison with the actual rate of the reference user equipment within the first time interval or with the subscription rate of the reference user equipment. If the maximum value is greater than or equal to the actual rate of the reference user equipment, determining the reference user equipment as limited reference user equipment; or if the maximum value is greater than or equal to the subscription rate of the reference user equipment, determining that the reference user equipment is the limited reference user equipment.

If the maximum value is smaller than the actual rate of the reference user equipment, determining the reference user equipment as the unlimited reference user equipment; or if the maximum value is smaller than the subscription rate of the reference user equipment, determining that the reference user equipment is the unlimited reference user equipment.

After the base station determines the unrestricted reference user equipment in the plurality of reference user equipment according to the above mode, the base station judges whether the ratio of the unrestricted reference user equipment in the plurality of reference user equipment to the plurality of reference user equipment meets the congestion-free condition of the cell; if the ratio of the unrestricted reference user equipment to the plurality of reference user equipment in the plurality of reference user equipment meets the congestion-free condition of the cell, determining that the cell is not congested; or, if the ratio of the unrestricted reference ue to the multiple reference ues does not satisfy the congestion free condition of the cell, determining that the cell is congested.

Wherein the ratio of the unrestricted reference ue of the multiple reference ues to the multiple reference ues satisfying the congestion free condition of the cell may be: the ratio of the limited reference user equipment in the plurality of reference user equipment to the plurality of reference user equipment is larger than a preset third ratio.

In the embodiment of the present invention, if it is determined that the cell is congested, it may be further determined whether the cell is overloaded, specifically: the base station may determine whether a ratio of the unrestricted reference ue of the plurality of reference ues to the plurality of reference ues satisfies a no-overload condition of the cell, determine that a load status of the cell is congested if the ratio of the unrestricted reference ue of the plurality of reference ues to the plurality of reference ues satisfies the no-overload condition of the cell, and determine that the load status of the cell is overloaded if the ratio of the unrestricted reference ue of the plurality of reference ues to the plurality of reference ues does not satisfy the no-overload condition of the cell.
