Implementing method for double mode terminal service keeping under network congestion

Abstract

A method for realizing communication service maintaining of double-module terminal at the state of network congestion comprises the following steps: establishing a wireless link to a first mode network by the double-module terminal for executing service transfer of data or sound; at the state that the first mode network generates wireless resource shortage or network congestion, negotiating with a second mode network by a first mode network according to the double-module property of terminal, requesting to establish the service channel to the terminal on the second mode network; determining whether the establishing of service channel to the subscriber is allowed by the second mode network, if the transmission is allowed, transferring the service parameter to be established to the first mode network, and then transmitting to the terminal, switching the terminal from a first mode to a second mode for continuing the service; and refusing the accessing of terminal if the transmission is not allowed. The method of the invention settles the condition that a certain standard network in the double-module network coexistence area has unbalanced load, increases the usage factor of wireless resource of double-module network, reduces the risk of service interruption thereby increasing the communication service quality of user terminal.

Description

technical field [0001] The invention relates to a method for realizing communication service maintenance of a wireless mobile terminal, in particular to a method for realizing communication service maintenance of a dual-mode wireless terminal under the condition of network congestion. Background technique [0002] The wireless resources provided by a wireless network, including power, frequency domain, time domain and code domain, etc., are always limited. In order to make full use of these limited resources to satisfy as many users as possible, cellular technology is usually used to realize the effective utilization of wireless resources. use. Each wireless cell divided according to space can provide wireless access services to users in the covered area, but it is still limited by wireless resources. In the actual use process, the resources of the wireless cells still cannot meet the needs of users. For example, when the number of users in the coverage area of ​​the cell i...

Problems solved by technology

In the manual switching mode, the user needs to manually select the favorite network, and cannot switch during the call

Automatic switching means that the dual-mode terminal continuously monitors the signal strength and quality of the communication port. According to the strength of the two network signals, it automatically switches to the network with strong signal in the standby and call states. In actual use, such as dual-mode terminal In the ongoing business communication including voice business and data business, the network is congested, and the network can no longer continue to provide business services. In the existing technology, the network side generally informs the user to reduce the rate or reconfigure the channel through signaling, or even delete the link, reducing the service quality, thereby affecting customer satisfaction

The existing technology does not give full play to the advantages of dual-mode terminals, and still uses the existing processing method of single-mode terminals, resulting in unguaranteed service quality, especially for high-speed services. The service maintenance processing method based on the characteristics of the modular terminal
