Problems solved by technology
[0031] Converting multimedia services to ordinary voice services requires the establishment of RBs, and converting ordinary voice services to multimedia services requires the release of RBs. Configuring RB requires multiple message exchanges on the air interface, resulting in increased delay, reduced user experience, and increased air interface signaling load.

Embodiment Construction
[0084] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0085] The core idea of the present invention is to establish a combined service including videophone multimedia service and ordinary voice service when the conversation service is established for the first time, and select one of the service modes according to the instruction of the first request, and when the service is required During the conversion, according to the instruction of the second request, another business method is selected to realize the business conversion.

The invention discloses a service conversion method, a service conversion device and a service conversion system. The method comprises the following steps that: a radio network controller (RNC) receives a first request message from a core network (CN); the RNC selects a first service from a pre-generated combination service according to a selection instruction in the first request message; and when service conversion is performed, the RNC receives a second request message from the CN and selects a second service from the pre-generated combination service according to a selection instruction in the second request message. The combination service is established and converted into different services according to different instructions so that processes such as the establishment or release of a radio bearer (RB), the deletion of an old transmission channel and the establishment of a new transmission channel on an Iub interface and the like during service conversion are avoided, null signaling load is lowered, a service conversion process is unified, service conversion is independent of the version of a terminal and the service conversion is easy to realize.
Description
Technical field [0001] The present invention relates to the technical field of computer networks, in particular to a method, device and system for business conversion. Background technique [0002] In the existing 2G (Second Generation, second-generation communication technology) communication technology, users implement communication between mobile terminals through ordinary voice services. 3G communication technology (3rdGeneration, third-generation mobile communication technology) is developed on the basis of 2G communication technology. It can communicate between mobile terminals through ordinary voice services and videophone multimedia services. When communicating based on videophone multimedia services, not only the voice of the other party can be heard, but the image of the other party can also be seen. [0003] As a relatively mature communication technology, 2G communication technology is still in an advantageous position for a period of time due to its wide network distr...
