Problems solved by technology

This will result in the interruption of the voice service
Alternatively, when a link for transmitting LTE data services is established between the user equipment and the LTE access network, if the user equipment requests a voice call service, the user equipment needs to disconnect the link with the LTE access network, and then Establish a link with the GSM access network, which will cause interruption of data services

Embodiment Construction

[0018] figure 1 A schematic diagram of a communication network topology according to an embodiment of the present invention is shown. The communication network 100 includes a core network 110 , a gateway 120 , a first access subnet and a second access subnet, and a user equipment 150 . Wherein, the first access subnet and the second access subnet may respectively include multiple baseband processing units. Here, for simplicity, only the baseband processing unit 131 of the first access subnet and the baseband processing unit 132 of the second access subnet are shown. In addition, the first access subnet and the second access subnet may respectively include multiple radio frequency units (Remote Radio Head: RRH). Here, for simplicity, only the radio frequency unit 141 of the first access subnet and the radio frequency unit 142 of the second access subnet are shown. The core network 110 is connected to the first access subnet and the second access subnet through the gateway 14...

Abstract

The invention relates to an accessing method in a first accessing subnet of a wireless communication network. The accessing method includes the following steps: establishing initial connection between the subnet and a user device; receiving a second service request from the user device; forwarding the second service request to a core network; receiving second service downlink data from the core network or second service uplink data from a second access subnet; sending the second service downlink data to the second access subnet, or sending the second service uplink data to the core network; and the wireless communication access technology adopted for the first access subnet and the wireless communication access technology adopted for the second access subnet are different. Through the accessing method, the limitation on the data rate of the user device by different wireless accessing technologies can be eliminated, the user device can enjoy various types of service simultaneously, and the network architecture can be simplified.

Description

technical field [0001] The present invention relates to a wireless communication network, in particular to a method for accessing in a wireless communication network. Background technique [0002] In the access network of the wireless communication network, there are access subnets using different wireless communication access technologies, such as the Global System for Mobile Communication (GSM) access network, the Universal Mobile Telecommunications System (Universal Mobile Telecommunications System: UMTS) access network, time division duplex synchronous code division multiple access (TDD-Synchronization Code Division Multiple Access: TD-SCDMA) access network, long term evolution (Long Term Evolution: LTE) access network, microwave access global Worldwide Interoperability for Microwave Access (WiMax) access network, etc. These access subnetworks respectively have links to the core network, and can respectively establish links with user equipment, so as to access the user ...
