Abstract
The invention relates to a mobile system in which the radio interface rate of a traffic channel and the intermediate rate of a transmission channel restrict the number of bits available for the transmission of terminal interface statuses (S), network independent clocking (N) and subchannel numbering (#) of a multichannel data link. In the invention, the bits form a subframe (n, . . . , n+10) and the status and control information are multiplexed inside successive subframes in a superframe structure (SUPERFRAME). In other words, the capacity of the bits available for the control information is shared by various kinds of control information by means of the superframe structure.
Claims19
A method of transmitting terminal interface user data and status information and any other control or synchronization information in protocol data units through a traffic channel or a group of traffic channels in a telecommunication system, comprising
- allocating for said status and control information a number of bits inside or outside the user data bit stream from protocol data units, the number of the allocated bits being smaller than the total number of bits in the status and control information,
- using at least one of said allocated bits to indicate a start of a superframe that includes said allocated bits from at least two protocol data units from, and
- multiplexing said status and control information inside said allocated bits within said subframe.
A method of transmitting terminal interface user data and status information and any other control or synchronization information in protocol data units through a traffic channel or a group of traffic channels in a telecommunication system, comprising
- allocating for said status and control information a number of bits from a transmission frame in which the user data is transmitted over the transmission links of a mobile communication network, the number of the allocated bits being smaller than the total number of bits in the status and control information,
- using at least one of said allocated bits to indicate a start of a superframe that includes said allocated bits from at least L transmission frames, where L is an integer and L≧2,
- multiplexing N-bit status and control information into said allocated bits inside said superframe that comprises L M-bit subframes, where M and N are integers and N>M≧2,
- transmitting said superframe in M allocated bits in L successive transmission frames over a transmission link of the mobile network, and
- transmitting said superframe in M allocated bits in L successive radio bursts over the radio path.

- allocating for said status and control information a number of bits inside or outside the user data bit stream from protocol data units, the number of the allocated bits being smaller than the total number of bits in the status and control information,
- using at least one of said allocated bits to indicate a start of a superframe that includes said allocated bits from at least two protocol data units, and
- multiplexing said status and control information inside said allocated bits within said super-frame,
- said status and control information comprising terminal interface status information, the subchannel and/or frame numbering of the high-rate data transmission service, and the code words of network independent clocking.
Transmission and reception equipment for transmitting the terminal interface user data and status information and any other control information in protocol data units through a traffic channel in a telecommunication system, comprising
