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

Embodiment Construction
[0040] The present invention proposes a kind of communication method based on USSD, mainly comprises the following steps:
[0041] Step 1: The network side receives the USSD request signaling sent by the terminal;
[0042] Step 2: judge the USSD request signaling and perform priority judgment according to the predetermined importance difference, the importance difference means that the USSD service is a common query application or a USSD application involving user privacy and information security;
[0043] Step 3: Determine whether the current network status is busy or idle;
[0044] Step 4: If the USSD request is a common application and the network is busy, abort the USSD request; if the USSD request is a common application but the network is idle, follow the normal USSD process; if the USSD request is an advanced application, Follow the advanced USSD process;
[0045] The common USSD process refers to the definition of the USSD service in the standard agreement;
[0046]...

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 technical field of wireless communication, and more specifically, to a communication method, system and device based on USSD. Background technique [0002] USSD (Unstructured Supplementary Service Data, Unstructured Supplementary Service) is a new type of interactive mobile data service based on the mobile communication network. The advantages of high reliability can make up for some technical deficiencies 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 of establishing multiple signaling connections is reduced, and the response time for one round trip is shorter than that of short message service, the shortest is one-seventh of short message ; [0004] 2) Convenient, the user can directly enter the USSD command string to communicate without having to select the menu level by leve...
