Problems solved by technology

[0006] However, the existing technical solutions only consider the carrying capacity of the wireless network, that is, the service rate that the network can provide, without specifically distinguishing the types of services carried, so that the design of the offloading scheme ignores the service QoS requirements. Therefore, the offloading algorithm not perfect

Embodiment Construction

[0051] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0052] The heterogeneous wireless network in the embodiment of the present invention takes LTE and WLAN as examples, and constructs a service distribution transmission system based on channel feedback information. Taking the real-time video transmission business as an example, a video distribution system and method based on QoS guarantee is proposed. The system of the present invention is also applicable to other types of heterogeneous wireless network environments.

[0053] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0054] Such as figure 1 As shown, the heterogeneous network environment in the present invention takes...

Abstract

The invention relates to the technical field of wireless communication, and discloses a service shunting system and a service shunting method based on feedback information under a heterogeneous network. The invention combines a quality of service (QoS) requirement of a service and bearing capacity of a wireless network, and provides a shunting strategy based on QoS assurance so as to regulate service shunting scaling factors in the heterogeneous network, therefore a service demand and a heterogeneous wireless network resource are dynamically matched, service quality which is accepted by a user is guaranteed, and resource utilization efficiency of the wireless network is maximized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a service distribution system and method based on feedback information under a heterogeneous network. Background technique [0002] With the development of wireless communication technology, wireless networks of various access technologies are constantly emerging. In terms of wireless applications, the demand for high-speed, real-time, and interactive user services is also increasing. In order to meet the service quality requirements of such services, higher requirements are put forward for wireless networks that provide bearer functions. However, considering the huge number of users and limited bandwidth resources in the current wireless network, each user can only obtain a limited service rate. Therefore, relying on only one wireless bearer network can no longer meet the throughput of all users with high bandwidth requirements. Latency, packet loss and ...
