Problems solved by technology

However, the total capacity control method generally allows any bearer to use the memory when the memory is sufficient. Once the memory is urgent, the high-priority bearer is likely to have no memory available, resulting in packet loss for the high-priority bearer; while the average The allocation rule is to allocate the same size of memory for each bearer, which will lead to the problem of insufficient memory for some bearers and waste of memory for other bearers, so that the memory requirements of more bearers cannot be met. In order to support more bearers, it is often necessary to Provide more memory resources, resulting in waste of memory resources
In summary, the existing memory allocation methods are difficult to meet the QoS requirements of multiple bearers

Embodiment 1

[0079] refer to figure 2 , which shows a flow chart of the steps of Embodiment 1 of a method for controlling memory in a base station according to the present invention, which may specifically include:

[0080] Step 201. During the data transmission process of the system, when the current memory demand value of the system exceeds the total memory supply threshold of the system, determine the bearers that meet the preset penalty conditions among the established bearers;

[0081] In the embodiment of the present invention, the data transmission process of the system may specifically include: the process of the system receiving data and the process of sending data by the system, such as the aforementioned process of PDCP receiving data and PDCP submitting data to RLC.

[0082] In a specific application, data can be received for the established bearer. When the current data to be received arrives, if the current memory demand value of the system exceeds the total memory supply th...

Embodiment 2

[0094]The method for controlling memory in a base station in this embodiment may further include the following optional technical solutions on the basis of the first embodiment above.

[0095] In this embodiment, the aforementioned preset penalty conditions may specifically include: the carried memory has an overrun characteristic and a rollback characteristic.

[0096] Among them, the overrun feature can be used to indicate that the actual memory value of the current bearer is greater than the ideal memory value; the fallback feature can be used to indicate the difficulty of the current bearer being released. For example, in a specific application, some caches in PDCP store For PDCP SDUs not submitted to RLC, these data can be easily released when the memory is tight, so these caches are relatively easy to release, and these caches can be considered to have rollback characteristics; while other caches in PDCP store The most important thing is the PDCP PDU that has been submit...

Embodiment 3

[0107] refer to Figure 4 , which shows a flow chart of steps in Embodiment 3 of a control method for base station memory according to the present invention, which may specifically include:

[0108] Step 401. When the system receives data, when the current memory demand value of the system exceeds the total memory supply threshold of the system, determine the bearers that meet the preset penalty conditions among the established bearers;

[0109] Step 402, releasing the overrun memory of the bearer that meets the preset penalty condition; wherein, the overrun memory is used to indicate the part where the actual memory value of the bearer exceeds the ideal memory value;

[0110] In a specific application, if the current memory demand value of the system still exceeds the total memory supply threshold of the system after finding the penalty bearer and releasing its overrun memory, you can continue to find a new penalty bearer to release according to the above-mentioned steps for ...

Abstract

An embodiment of the invention provides a control method and device for a base station memory, wherein the method concretely comprises the steps of in a process of data transmission of a system, when the memory requirement value of the system at present exceeds a memory supply total threshold of the system, determining loaders according with preset punishment conditions in established loaders; releasing the ultralimit memory of the loaders according with the preset punishment conditions, wherein the ultralimit memory is used for expressing a part of an actual memory value of the loaders exceeding an ideal memory value. The embodiment of the invention can improve the use ratio of memory resources.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a control method and device for base station memory. Background technique [0002] 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) is a standardization organization established in December 1998. The continuous growth of mobile communication services promotes the development of LTE (Long Term Evolution, Long Term Evolution) specification by 3GPP. [0003] In order to ensure QoS (Quality of Service), the base station of the LTE system generally considers how to ensure QoS characteristics from the aspects of scheduling strategy, buffer queue management, and link layer configuration. In addition, it is also necessary to study how to allocate limited Memory resources to meet the QoS requirements of multiple bearers. [0004] Common memory allocation methods specifically include the total amount control method and the average distrib...
