Abstract
The invention discloses a kind of methods of terminal challenge access, system and device, in terminal before carrying out uplink contention access, cell base station is that terminal distribution cell level mark is sent to terminal, and itself establish terminal cell level mark and terminal the unique identification of wireless network corresponding relationship, instruction terminal initiates the request of uplink contention access using the cell level mark distributed in uplink contention access, the cell level mark that the uplink contention access carries is converted to the terminal user after the unique identification of wireless network according to corresponding relationship by cell base station, it is sent to wireless network network side, realize the uplink contention access process of terminal.Since relative to terminal occupied ascending resource when the unique identification of wireless network is in uplink contention access is used, the occupied ascending resource of terminal housing estate level identification is much smaller, so reducing the consumption to ascending resource when terminal carries out uplink contention access.
Description
Technical field
The present invention relates to the access technology of wireless network, in particular to a kind of method, system and the dress of terminal challenge access
It sets.
Background technique
In the wireless network, there are many modes, and the transmission of the data between the network side of wireless network and terminal may be implemented,
One of which is exactly to occupy ascending resource by the method for uplink contention access, carries out the transmission of data.Institute in this way
The small bag data of the lower periodicity of the data of transmission, generally time delay sensitivity, such as persistently connection packet (keep-alive), can
The expense of wireless signaling is greatly lowered.
Fig. 1 is the method flow diagram that prior art terminal transmits data by the way of uplink contention access, specific to walk
Suddenly are as follows:
Step 101, cell base station, which are sent in cell using the T1 time cycle property of setting by broadcast, can be used for uplink
The ascending resource Time-Frequency Information of contention access；
Terminal in step 102, cell gets the ascending resource time-frequency letter that can be used for uplink contention access by broadcast
After breath, the request of uplink contention access is initiated on the ascending resource, which requests carried terminal in wireless network
Unique identification；
In this step, which can be international mobile subscriber identity (IMSI) in the unique identification of wireless network；
In this step, there are multiple terminals that can send uplink access request in the ascending resource simultaneously；
Step 103, cell base station receive the carried terminal of the transmission of multiple terminals in cell in the unique of wireless network
After the contention access request of mark, it is sent to wireless network network side and carries out clash handle, wireless network network side determines uplink
Compete successful terminal, according to determined uplink compete successful terminal wireless network unique identification by cell base station to
The terminal of success uplink contention access sends hybrid automatic repeat-request (HARQ)；
Step 104, the terminal for receiving HARQ occupy ascending resource transmission data；The terminal for not receiving HARQ is random
It delays a period of time and initiates the request of uplink contention access on the ascending resource again, be until successfully occupying the ascending resource
Only.
It can be seen that from process shown in FIG. 1 and terminal and wireless network network side realized using uplink contention access mode
Between transmit data, since wireless network network side does not need to establish connection with terminal, thus cell base station need it is competing in uplink
It strives and knows terminal when access in the unique identification of wireless network and be transmitted to wireless network network side, such as IMSI, so that wirelessly
Network of network side identification terminal.
In uplink contention access, cell base station will obtain terminal in the unique identification of wireless network, and terminal is in wireless network
Unique identification to be carried and transmit by ascending resource in uplink contention access, however terminal is in the unique identification of wireless network
Byte number it is relatively more, such as IMSI occupies 60 bits to identify a terminal, this will occupy excessive uplink money
Source.Since the ascending resource in uplink contention access process is limited, ascending resource carrying terminal wireless network unique mark
Know the consumption that can be increased to ascending resource.
Summary of the invention
In view of this, the embodiment of the present invention provides a kind of method of terminal challenge access, this method can be carried out in terminal
The consumption to ascending resource is reduced when uplink contention access.
The embodiment of the present invention also provides a kind of system of terminal challenge access, which can carry out uplink competition in terminal
