Problems solved by technology

In the traditional network service transmission process, the relevance of network services is not considered. Different user requests need to establish network connections according to the above steps, and carry out service transmission independently. Therefore, services with the same content may be used by multiple users. repeated transmissions, resulting in a waste of physical resources

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] The network data pre-push method based on multicast proposed by the present invention, its flow chart is as follows figure 1 shown, including the following steps:

[0033] (1) When a terminal that supports network data pre-push has a network data request, it searches the pre-push data cache according to the content of the request to find out whether the requested data content has been received through pre-push at a certain point before.

[0034] (2) The terminal requesting the service generates uplink data, and puts the information of its own service request into the uplink message. According to whether the business data requested this time has been successfully received through the pre-push method, or the terminal needs to update the data, the terminal decides whether to receive new data, and attaches a Flag bit to the uplink message of the dec...

Abstract

The invention discloses a multicast-based network data pre-pushing method, and belongs to the technical field of wireless network data transmission. In wireless network data transmission, when a user requests network data, according to task request analysis and current network channel states, a base station determines whether the task is pre-pushed in a multicast manner to users with similar internet use habits and within the coverage area of the base station or in neighboring cells; according to a prior probability function of user's internet use habits accumulated previously and channel states of active users, an alternative user scheme, a multi-cell coordinated transmission scheme and a modulation coding scheme that all participate in multicast pre-pushing are calculated; expected revenue which can be obtained by adopting the multicast manner is calculated; and compared with a conventional unicast manner, if the multicast manner obtains the revenue greater than a set threshold value, the multicast-based network data pre-pushing method is adopted for pushing, otherwise, a conventional method is adopted for pushing. The multicast-based network data pre-pushing method can effectively improve the wireless spectrum efficiency and the energy efficiency, and optimizes the transmission performance of the network on the whole.

Description

technical field [0001] The invention relates to a multicast-based network data pre-push method, belonging to the technical field of wireless network data transmission. Background technique [0002] With the increase in the number of smart phones and handheld mobile terminals, the data traffic of the mobile communication network will increase significantly in the future, and most of the data traffic will come from web browsing and network video services. In order to meet the rapidly growing service demands with limited physical resources, future wireless mobile communication systems must have higher transmission rates, higher spectrum utilization, and lower energy consumption. [0003] In traditional wireless data transmission, the general process for terminals with network service requirements to obtain services is as follows: [0004] 1. The terminal reads network system information and randomly accesses resources [0005] 2. The terminal randomly accesses, and re-initi...
