Service data transmitting and emitting method and relevant device

Abstract

The embodiment of the invention discloses a service data transmitting method and a base station controller, wherein the method comprises the steps as follows: the base station controller BSC allocates access resource for a terminal on a packet data traffic channel PDTCH according to a channel access request emitted by the terminal; the BSC receives the service data emitted by the terminal through the allocated access resource; and the BSC launches an unstructured supplementary service data USSD service to a core network, and transmits the service data to the core network in the USSD service. The embodiment can save the network overhead when transmitting the service data, thus saving network resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for transmitting and sending service data and related devices. Background technique [0002] With the extensive development of M2M (Machine to Machine, machine-to-machine) services, the M2M services put forward new requirements for the existing GSM wireless data bearer technology. Among them, the M2M service is characterized by frequently sending a small amount of data to the network. For example, for some real-time data collection services, sensors need to send data to the network at very short intervals, and the amount of data sent each time is very small, perhaps only a dozen bytes. [0003] The current network design is for common voice and data services. Among them, the existing USSD (Unstructured Supplementary Service Data, unstructured supplementary service data) service is a supplementary data service in the circuit domain, and the servic...

Problems solved by technology

However, using PDTCH parameter service data involves complex processes, such as GPRS Attach process and PDP Context Activation process

The complex process will further bring relatively large signaling overhead

At the same time, at the application level, the IP address overhead of terminals and application servers on the IP transport layer is also relatively large

These signaling overheads and IP address overheads will consume a lot of network overhead, and when transmitting M2M service data, it will greatly waste network resources

[0005] In short, the existing wireless data bearer technology cannot meet the needs of M2M services, and a new wireless data bearer method needs to be provided to save network overhead when transmitting M2M service data, thereby saving network resources
