Embodiment 1

[0077] Embodiment 1 provides a structure of the MAC PDU used on the multiplexed forward access channel, such as figure 1 shown. In the layer 3 signaling during the establishment process, the logical channel category of the bearer has been agreed, and the terminal identification number can only use the type of CRNTI (Cell Radio Network Temporary Identification Number). The media access control header includes N (the value of N is k) and k groups of sub-headers, corresponding to k media access control service data units, and padding is used at the end to align them. The subheader includes UE-Id, C / T, LI.

Embodiment 2

[0078] Embodiment 2 provides a structure of the MAC PDU used on the multiplexed forward access channel, such as figure 2 shown. In the layer 3 signaling during the establishment process, the logical channel category of the bearer has been agreed, and the terminal identification number can only use the type of CRNTI (Cell Radio Network Temporary Identification Number). And limit that only one logical channel is allowed to be mapped to the transport channel. The media access control header includes N (the value of N is k) and k groups of sub-headers, corresponding to k media access control service data units, and padding is used at the end to align them. The subheader includes UE-Id and LI.

Embodiment 3

[0079] Embodiment 3 provides a structure of the MAC PDU used on the multiplexed forward access channel, such as image 3shown. In the layer 3 signaling during the establishment process, the logical channel category of the bearer has been agreed, and the terminal identification number can only use the type of CRNTI (Cell Radio Network Temporary Identification Number). And all the media access control service data units of different terminals multiplexed in one MAC PDU have the same length, and indicate the specific length. The media access control header includes N (the value of N is k) and k groups of sub-headers, corresponding to k media access control service data units, and padding is used at the end to align them. The subheader includes UE-Id, C / T.

Abstract

The present invention provides a method for preserving a permanent online service, which includes three steps. Firstly, the service data packages sent to different terminals in the same period are combined into a media access control protocol data unit; secondly, the media access control protocol data unit is transmitted via a downlink transmission channel used in the CELL-FACH state; thirdly, the different terminals respectively obtain the required service data packages from the media access control protocol data unit in order to preserve the permanent online type service. The present invention also provides a device for preserving the permanent online type service.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for maintaining an always-on service in a wireless communication system. Background technique [0002] The two basic modes of operation of a terminal are idle mode and connected mode. The connection mode can be further divided into different states: URA_PCH state (URA Paging Channel, access network registration area paging channel state, hereinafter referred to as URA_PCH), CELL_PCH state (CELL Paging Channel, cell paging forward access channel state, hereinafter referred to as CELL_PCH), CELL_FACH state (CELL Forward Access Channel, cell forward access channel state, hereinafter referred to as CELL_FACH), CELL_DCH (CELL Dedicated Channel, cell dedicated channel state, hereinafter referred to as CELL_DCH) state, these states define the physical channel used by the terminal kind of. [0003] The CELL_FACH state is one of the states in the connection mode. In...
