USSD-based communication method, system and device

Abstract

The invention relates to an unstructured supplementary service data (USSD)-based communication method, a USSD-based communication system and a USSD-based communication device. The USSD-based communication method comprises the following steps that: a network side receives a USSD request signaling sent by a calling party; the network side judges the priority of the USSD request signaling according to the importance difference and judges whether the current network state is busy or not; and the network side responds to the USSD request by combining the priority with the network busy state. Compared with the prior art, the USSD-based communication method can judge the priority of a USSD service according to a USSD service code, process the USSD service according to the priority and the current network state respectively, ensure that the high-priority USSD service is preferentially executed, save network resources to a certain degree and ensure the data transmission of important application.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and more specifically, to a communication method, system and device based on USSD. Background technique [0002] USSD (Unstructured Supplementary Service Data) is a new interactive mobile data service based on mobile communication networks. It is a brand-new service launched on the basis of the GSM short message system technology. The advantages of high reliability can make up for some technical shortcomings of traditional short messages. USSD has the following characteristics: [0003] 1) Fast. In interactive applications, since only one connection needs to be established, the time delay for establishing multiple signaling connections is reduced. The response time for one round trip is shorter than that of short message service, and the shortest is one-seventh of short message. ; [0004] 2) Convenient, users can directly input the USSD command string to communicate without hav...

Problems solved by technology

[0018] 1) The existing USSD technical solutions treat various applications equally, and do not reflect the differences in the importance of different applications, such as ordinary query services and recharge and transfer services that are related to user privacy and property security. There is a marked difference in gender;

[0019] 2) In addition, because the USSD service occupies the channel for a long time, if a certain period of time calls, text messages and other services are carried out simultaneously, there are many users using the channel, which is very easy to cause link congestion. At present, there is no mechanism that can intelligently according to the network status , processing USSD requests according to the importance level of USSD services often results in that when the network is congested, important USSD services cannot be guaranteed, and may affect basic services such as calls and text messages
