Problems solved by technology

Even for streaming traffic, which is mainly a one-way application, it is difficult to allocate the return direction to other users, because said users are likely to generate traffic in the other direction, thereby causing resource loss for streaming communication. unacceptable preemption of

Embodiment Construction

[0052] The present invention proposes to use existing wireless protocols and channels, which are used for real-time services as they are relayed through the MSC. The idea is to use dedicated channels instead of shared channels to exchange packet data units (PDUs) to and from the SGSN. If both real-time and non-real-time services are supported, existing Dual Transmit Mode (DTM) procedures can be used to control the setup and release of different data streams.

[0053] Recall briefly that the DTM function is the function that, for a mobile station capable of supporting two types of services simultaneously, by specifying that the BSS adjust the resources required for each of the modes so that the two types of services can be simultaneously is supported (in circuit mode and in packet mode). For a detailed description of the functions, reference may be made to corresponding specifications published by standardization organizations.

[0054] The change suggested by the present inv...

Abstract

A method of supporting real-time traffic in a mobile radiocommunications system comprising a radio access network and a core network, in which method the real-time traffic supported in packet mode in the network core is supported in the radio access network by allocating dedicated channels.

Description

technical field [0001] The present invention generally relates to mobile radio communication systems. Background technique [0002] In general, the systems are standardized and for further information reference is made to standards published by the relevant standardization organizations. [0003] In general, in the system, different types of services can be distinguished as a function of the required quality of service (QoS). In particular, it is possible to distinguish between real-time services, which correspond to communication traffic sensitive to transmission delays (such as especially applied to voice, or even "streaming" communication), and non-real-time services, which correspond to Communications that are not sensitive to transmission delays (eg, especially data transmissions). [0004] In general, in the system it is possible to differentiate between different types of services depending on the technology used to support them. Therefore, a distinction can be mad...
