Abstract

The invention relates to a system for the wireless transmission of a frame-synchronized signal between a base radio station (1) and at least one mobile terminal (2), which base radio station is provided for defining, prior to the transmission of data of a synchronous service, the periodically occurring frames which are to be used and a constant number of synchronous channels for the duration of the connection. The base radio station (1) and at least one mobile terminal (2) are provided for transmitting packets containing data of an asynchronous service in the frame-synchronized signal. The base radio station (1) is provided for defining for each respective frame a number of asynchronous channels used for transmitting the packets.

Claims

1. A system for a wireless transmission of a frame-synchronized signal comprising:

a base station;

a mobile terminal for communication with said base station;

wherein, prior to said transmission of said frame-synchronized signal of a synchronous service to said mobile terminal, said base station defines frames of said communication;

said frames being configured to include synchronous channels and asynchronous channels;

said asynchronous channels including packets containing data of an asynchronous service;

said base station further defining a number of said synchronous channels prior to said transmission, wherein said number is constant through said communication;

said synchronous channels having time frames which are different from each other.

2. The system of claim 1, wherein said frames periodically include said synchronous channels.

3. The system of claim 1, wherein said number of said synchronous channels repeat in successive ones of said frames.

4. The system of claim 1, wherein said number of said synchronous channels repeat in non-successive ones of said frames.

5. The system of claim 1, wherein said frames periodically include said synchronous channels with at least one of said frames not having said synchronous channels being interposed between said frames which include said synchronous channels.

6. The system of claim 1, wherein one of said frames includes a first set of said number of first synchronous channels and another of said frames includes a second set of said number of second synchronous channels, wherein said first synchronous channels are different from said second synchronous channels.

7. The system of claim 1, wherein said mobile terminal announces service requirement to said base station over control channels included in said frames, and wherein said base station forms an allocation of said synchronous channels and said asynchronous channels and provides said allocation to said mobile station over said control channels.

8. The system of claim 1, wherein said mobile station includes an insertion-cum-extraction device and a control device which controls said insertion-cum-extraction device to insert and extract synchronous data of said synchronous service into and from one of said synchronous channels, and to insert and extract asynchronous data of said synchronous service into and from one of said asynchronous channels.

9. The system of claim 1, wherein said base station allocates said synchronous channels per frame depending on quantity and priority of packets available in a buffer of one said base station and said mobile terminal.

10. A base station in a system for a wireless transmission of a frame-synchronized signal comprising:

a mobile terminal for communication with said base station;

wherein, prior to said transmission of said frame-synchronized signal of a synchronous service to said mobile terminal, said base station defines frames of said communication;

said frames being configured to include synchronous channels and asynchronous channels;

said asynchronous channels including packets containing data of an asynchronous service;

said base station further defining a number of said synchronous channels prior to said transmission, wherein said number is constant through said communication;

said synchronous channels having time frames which are different from each other.

11. A mobile terminal in system for a wireless transmission of a frame-synchronized signal comprising a base station for communication with said mobile terminal;

wherein, prior to said transmission of said frame-synchronized signal of a synchronous service to said mobile terminal, said base station defines frames of said communication;

said frames being configured to include synchronous channels and asynchronous channels;

said asynchronous channels including packets containing data of an asynchronous service;

said base station further defining a number of said synchronous channels prior to said transmission, wherein said number is constant through said communication;

said synchronous channels having time frames which are different from each other.
