Problems solved by technology

Since the heat distribution of content accessed by users accessed by a node is similar, when multiple MDs may obtain the same content from the same neighbor eNodeB at the same time, due to the independent peer-to-peer unicast transmission mechanism in the cooperative cache, a large amount of repeated traffic will be generated ( including requests and responses), consumes valuable link bandwidth resources

Embodiment Construction

[0050] The application scenario of the present invention is: a RAN includes an SAE-GW node, N eNodeB nodes, and the SAE-GW node manages the N eNodeB nodes.

[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0052] like figure 2 As shown, the present invention provides a management method for base station cache, including:

[0053] Step 101) generating a content popularity ranking table on the SAE-GW node;

[0054] Within a fixed time period, each eNodeB node counts the access times of each requested content according to user access requests, and reports to the SAE-GW node; the SAE-GW node counts the reported information of all eNodeB nodes, and generates a content popularity ranking table; content popularity The ranking table records the name of each content, the total number of visits and historical visit time data.

[0055] Step 102) dividing the local cache of each eNodeB node into a s...

Abstract

The invention provides a management method for base station cache. The method comprises the following steps: step 101, generating a content heat degree precedence table on a central gateway controller node; step 102, dividing local cache of each base station node into shared cache and unshared cache; step 103, storing the request content in the content heat degree precedence table into the local cache of each base station node according to the precedence; step 104, respectively establishing an undetermined precedence table on each central gateway controller node and each base station node. Based on the management method for the base station cache, the invention further provides a user access processing method which is realized based on a request aggregation and asynchronous multicast strategy. The management method disclosed by the invention can be used for lowering the redundancy rate of the base station cache, increasing the utilization rate of cache, reducing repeated flow rate inside and outside the network, quickening the network response speed and improving the internet-surfing experience of a user.

Description

technical field [0001] The invention relates to the technical field of mobile networks, in particular to a method for managing base station cache and a method for processing user access. Background technique [0002] With the increase in the number of smart phones and tablet users worldwide, the access to the Internet by mobile devices (Mobile Device, MD) is expected to grow rapidly (literature [1]: White Paper, "Cisco Visual Networking Index: Global Mobile Data , "2010-2015.). When an MD accesses content on the Internet, the content must be obtained from an origin server outside the mobile network. Content Delivery Network (CDN for short) is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can get what they need nearby. content, solve the Internet network congestion situation, and improve the response speed of users visiting websites. Technically, i...
