example 1

[0047] The processing flow of the resource adjustment method above is described in detail below, image 3 is a detailed flow chart of the resource adjustment method according to Example 1 of the present invention, such as image 3 As shown, the method includes the following steps:

[0048] In step 301, the eNB calculates the current resource usage according to the services currently occupying the resources allocated for the eNB (for example, received MBMS services and unicast services).

[0049] In step 302, the eNB notifies the MCE of the resource usage status. The representation of the resource usage status may be: the eNB reports whether the resource is idle, or whether there is data overflow; or, the eNB reports the ratio of the used resource to the allocated resource, for example, a percentage. That is, if the ratio of used resources to allocated resources is less than 100%, it is recorded as free resources; if the ratio of used resources to allocated resources is great...

example 2

[0056] The method provided by the embodiment of the present invention will be described below by taking an eNB having idle resources as an example.

[0057] Step 1: The eNB calculates the current resource usage according to the currently received MBMS service and unicast service as having idle resources.

[0058] Step 2: The eNB notifies the MCE of the resource usage status in each scheduling period.

[0059] Step 3: When the MCE knows that the current eNB resource status is idle resources, the MCE may appropriately reduce the radio resources used for MBMS, and notify the eNB of the adjusted result.

example 3

[0061] The method provided by the embodiment of the present invention will be described below by taking an eNB having idle resources as an example.

[0062] Step 1: The eNB calculates the current resource usage according to the currently received MBMS service and unicast service as having idle resources.

[0063] Step 2: The MCE instructs the eNB to report the reporting conditions of resource usage, and the eNB notifies the MCE of the resource usage status after meeting the reporting conditions.

[0064] Resource reporting conditions can be one or a combination of the following situations:

[0065] 1. Resource idle or overflow threshold. The threshold may be the size of a specific resource, for example, the number of idle or overflow bytes, the number of idle or overflow subframes, or the percentage of idle or overflow.

[0066] 2. The cycle of resource reporting. In each resource reporting cycle, the eNB sends the resource usage status. The eNB can report when the resource ...

Abstract

The invention discloses a resource adjustment method and a multi-cell / multicast coordination entity (MCE). For each evolved Node B (eNB) in one or more scheduled base station eNBs, the method comprises the following steps that: the eNB sends a resource using status of the eNB to the MCE; and the MCE adjusts the resource of the eNB according to the resource using status. The MCE comprises a receiving module and an adjustment module, wherein the receiving module is used for receiving the resource using status of the eNB from the eNB; and the adjustment module is used for adjusting the resource of the eNB according to the resource using status. By the method and the MCE, the resource can be flexibly adjusted according to the actual resource using condition, the phenomenon of resource waste or packet loss is effectively avoided, and the performance of a system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource adjustment method and a multi-cell / multicast coordination entity (Multi-cell / multicast Coordination Entity, MCE for short). Background technique [0002] In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3rdGeneration Partnership Project, referred to as 3GPP) proposed a multimedia broadcast multicast service (Multimedia Broadcast Multicast Services, referred to as MBMS). The target transmits data, realizes the resource sharing of the network (including the core network and the access network), and improves the utilization rate of the network resource (especially the air interface resource). MBMS defined by 3GPP can not only realize plain text and low-rate message multicast and broadcast, but also realize broadcast and multicast of high-speed multimedia services. Therefore, it can provide a variety of rich video, audio a...
