Embodiment Construction

[0052] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0053] It is mentioned in related technologies that in actual networks, due to the limitation of the number of carrier frequencies, some mobile operators do not have enough frequencies to deploy multiple HSPA and LTE systems at the same time, and mobile operators will adjust the HSPA and LTE systems according to the number of user equipment accessing the network. LTE carrier frequency. Under this kind of network deployment, the capacity of a single system may be insufficient, which limits the throughput of user terminals, and the load balancing between systems can only be achieved by switching and redirection, which will cause waste of resources.

[0054] In order to solve the above technical proble...

Abstract

The invention provides a data transmission method, equipment and a system. The data transmission method comprises the steps as follows: first network side equipment receives downlink business data from a core network and adopts first access technology; and the first network side equipment and the second network side equipment adopting second access technology cooperatively send the downlink business data to UE (Unified Equipment). The invention can solve the problems in the existing network deployment that the throughput of a user terminal is limited because the capacity of a single system is not enough and the resources are wasted because the load balance between the systems can be realized only in a switching and redirecting manner.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method, device and system. Background technique [0002] For wireless communication technologies, each is assigned a corresponding working frequency band, and each wireless communication system works in the planned frequency band. With the development of radio communication technology, the communication system requires an increasing transmission rate to meet the higher requirements of various wireless transmission services. The existing working frequency band of the communication system may not be able to meet the requirement of higher transmission rate, and a larger working bandwidth is required. [0003] Both LTE (Long Term Evolution, long-term evolution technology) and HPSA (High Speed ​​Packet Access, high-speed downlink packet access) systems have a layered protocol stack structure, from the lowest physical layer to MAC (Multiple Access Channel, multip...
