Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] In 3GPP, three types of operations for a Radio Access Bearer (RAB) assignment message are defined: bearer setup (RAB setup), bearer modification (RAB modify) and bearer release (RAB release). Among these three operations, bearer establishment and bearer release are the basic operation modes, while bearer modification is a higher-level ...

Abstract

The present invention provides a method and a device for bearer modification. The method comprises: when determining that bearer modification is required, maintaining a current ongoing service, and sending a bearer release request message to another network device, the bearer release request message being used for instructing the another network device to release a bearer that is already set up; and after determining that the another network device releases the bearer that is already set up, sending a bearer setup request message to the another network device, the bearer setup request message carrying modified bearer information, so as to instruct the another network device to set up a bearer according to the modified bearer information. The embodiments of the present invention ensure that end-to-end support can be achieved during bearer modification.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a bearer modification method and equipment. Background technique [0002] During the 3G call establishment process or in the steady state after the 3G call is connected, the call may trigger bearer modification as required. Among them, in the process of call establishment, the bearer of the calling side may be established before the called side, but in order to achieve codec-independent operation (Transcoder Free Operation, TrFO), after the bearer of the called side is established, the bearer will be transmitted through signaling The information is reversely transmitted to the calling side, triggering the modification of the bearer on the calling side, so that the whole process uses the same bearer parameters, thereby achieving TrFO. After the call is connected, the bearer may need to be modified due to service changes. [0003] The existing bearer modification standa...
