Embodiment Construction
[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than 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.
[0066] In the embodiment of the present invention, the packet transport network PTN allocates corresponding data paths for each sub-service in the communication system business, wherein there are at least two data paths corresponding to the sub-services; , transferring the sub-service with high service priority corresponding to the differentiated service code DSCP of the sub-service to a data path where no congestion occurs; wherein, the se...

The invention discloses a method and device for allocating transport channels. The method comprises the steps of that a packet transport network PTN allocates corresponding data channels to each piece of subservice in communication system service, wherein at least two data channels correspond to the subservice; and the PTN transfers the subservice to the data channels in which congestion does not occur after the congestion occurs in the data channels, wherein the subservice is the subservice with a high service priority corresponding to a differentiated service code point DSCP of the subservice, and the service priority corresponding to the DSCP of the subservice is determined according to a DSCP value corresponding to the subservice transparently transported by a service gateway SGW. The problem that in the prior art, packet loss occurs in 4G_LTE (Long Term Evolution) subservice at the same time when fault phenomena such as congestion occur in a network due to the fact that the priority practically corresponding to the subservice in 4G_LTE is consistent is solved.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for allocating transmission paths. Background technique [0002] QoS (Quality of Service) refers to a network that can use various basic technologies to provide better service capabilities for specified network communications. It is a security mechanism for the network and is used to solve network delays and congestion. A technique for the problem. Under normal circumstances, QoS is not required if the network is only used for specific application systems with no time limit, such as Web (web page) applications, or E-mail (Electronic mail, email) settings, etc. But it is very necessary for key applications and multimedia applications. When the network is overloaded or congested, QoS can ensure that important traffic will not be delayed or discarded, and at the same time ensure efficient operation of the network. [0003] All high-speed Internet services (...
