Problems solved by technology

[0053] It can be seen that based on the existing 802.21 standard, heterogeneous handover in 3GPP will cause a delay of 300 milliseconds only in reverse access and wireless resource allocation, and a delay of 300 milliseconds will interrupt many services
[0054] In addition, during the handover process, if the terminal does not provide detailed terminal capability information and service type information to the target netw

Embodiment Construction

[0086] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0087] In the present invention, when the terminal performs heterogeneous network switching, it does not directly transmit the first information of the terminal through reverse competition (the first information is used for the terminal to negotiate with the target network to establish the terminal's wireless service connection), and It is to send the first information of the terminal to the target network through the source network to avoid conflicts during the access process and speed up the access speed; the target network reserves resources for the terminal according to the received first information, and sends the information to the terminal through the source network. The reserved resource information is returned to the terminal; the terminal establishes a wi...

Abstract

The invention is related to the field of radio communication and discloses an isomeric network switching method, system, terminal and network. When conducting a switching of the isomeric network, the invention is able to avoid a reverse access competition between the terminals, thereby improving the success rate of network access and reducing the service interruption time caused by the switching. In the invention, when the isomeric network switching is conducted at the terminal, the first message of the terminal that is used to negotiate with the target network for establishing wireless service connections is sent to the target network via the source network. The target network reserves resources for the terminal according to the first message received and send back the message of the reserved resources to the terminal through the source network. The terminal establishes wireless service connections according to the reserved resources and accesses to the target network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to heterogeneous network switching technology. Background technique [0002] With the rapid development and popularization of communication technologies, mobile phones and the data services they provide have increasingly changed people's lives and work. At the same time, in response to the needs of the market, operators have developed various communication technologies according to the different needs of users, forming a status quo where multiple communication technologies coexist. It is not uncommon to see multiple mobile cellular technologies co-existing in the same area, and the same cellular technology being operated by different operators. Users can perform roaming switching and network selection among various communication systems according to the differences in service types and service quality of different networks, such as figure 1 shown. [0003] Handover is unique...
