Description

Access method and device

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to an access method and apparatus. BACKGROUND OF THE INVENTION The CELL_FACH (Cell Forward Access Channel) state is a constant state of a smartphone, and the CELL_FACH state has the following advantages -

1. Applicable to user equipment (User Equipment, UE for short) Keep small traffic data, such as Weibo, WeChat, and QQ online.

2. The CELL FACH state uses a common channel, which saves dedicated resources compared to the CELL DCH Channel (CELL DCH) state.

3. The CELL_FACH state is compared with the cell paging channel (CELL_Paging Channel, S卩 CELL_PCH) state, and the uplink access channel is configured to perform uplink data transmission. In the CELL_PCH state, if there is uplink data transmission, it must be migrated to the CELL_FACH state. The state transition will increase the signaling overhead.

Although CELL_FACH has the above advantages, the radio is in the process of receiving the forward access, the random access channel (RACH), and the forward access channel (FACH). Open state, high power consumption. The inventors found that the above-mentioned techniques have the following problems during the research:

1. FIG. 1 is a schematic structural diagram of configuration information of an FMO according to the related art. As shown in FIG. 1, the UE is within a 128-frame period of a FACH Measurement Occasion (FMO) period. The time period (generally no more than 2 frames long) is used for measurement, and other time periods can be used for forward access. Therefore, if multiple UEs access simultaneously in the same time period, a collision occurs, and uplink transmission is increased. The delay of the data; and in the forward access process, the radio of the UE needs to be in an open state, so that the UE consumes more power.

2. There is no corresponding mechanism in the related art to dynamically change the duration of forward access in the CELL_FACH state. Therefore, the transmission rate of the CELL_FACH state cannot be dynamically adjusted, and the switching probability of the CELL_FACH state to the CELL_PCH state and the CELL DCH state is increased. In view of the fact that the forward access process in the related art leads to a large amount of radio frequency power consumption of the UE, an effective solution has not been proposed yet.
