Step 301, the user plane functions of center cell receive the downlink data for being sent to terminal, subsequently into step
302。
Step 302, the chain of command function of center cell determine the transmission point set that terminal may be resident, the use of center cell
Family face function by the downlink data be sent to it is all transmission point sets in transfer points, by the transfer point receive it is described under
Downlink data transmission is carried out after row data.
In the present embodiment, the user plane functions of center cell can pre-save number as downlink data transmission anchor point
According to " data packet head " information of bag, packet is matched with target terminal, the user plane functions of center cell by with control
Face function processed interacts the transmission point set for determining that terminal may be resident.
Optional mode one, the chain of command function of center cell determine the transmission point set that terminal may be resident, center cell
The transfer point that may be resident to all terminals sends beep-page message, and the terminal of the terminal is carried in the beep-page message
Mark, wherein, the terminal iidentification is by the chain of command function distribution of the center cell when the terminal initial accesses；
The center cell receives the terminal location instruction for the terminal that the transfer point that the terminal is currently resident is sent, the terminal
Position instruction carries the terminal iidentification；The downlink data and the terminal iidentification are sent to the end by the center cell
The currently resident transfer point in end.
Optional mode two, the chain of command function of center cell determine the transmission point set that terminal may be resident, the center
The terminal iidentification of the downlink data and the terminal is sent to the transfer point that all terminals may be resident by unit, by institute
Transfer point wave point is stated to be transmitted the downlink data and terminal iidentification by broadcast channel or PCH, wherein,
The terminal iidentification is distributed when the terminal initial accesses by the center cell.
For above-mentioned optional mode two, methods described also includes：The center cell may be resident to all terminals
Transfer point send number of retransmissions parameter, the number of retransmissions parameter is used for that controlling transmission point wave point is maximum blind to be retransmitted time
Number.It should be noted that the occurrence of number of retransmissions parameter is not limited in the present embodiment.

In the present embodiment, by above-mentioned downlink data transmission mode, solve in following 5G access net systems framework, control
After face function processed separates with user plane functions, the transmission of downlink data is realized.
Second embodiment
With reference to the network architecture in Fig. 2 application scenarios, downlink data transmission flow shown in Figure 4, at this
In embodiment, after downlink user face data or control plane signaling arrival center cell, triggering the seeking for terminal of center cell
Exhale process, beep-page message is sent to the transfer point that all terminals may be resident by center cell, and terminal is sent out after receiving beep-page message
Play the access procedure of networking side, in access procedure, center cell determines the transfer point of terminal access, and by downlink data or
The transfer point that signaling is accessed by terminal is sent to terminal.Comprise the following steps that：
Step 400, in pre-provisioning procedure, center cell is terminal distribution terminal iidentification, and it is different types of under
Logic channel ID corresponding to row high level data type, and the encryption for different descending high level data types or integrity protection
Parameter.
Above-mentioned terminal iidentification (alternatively referred to as access network terminal iidentification or terminal temporary mark) is accessed in terminal initial
When by center cell chain of command function distribution.
After step 401, descending high level data reach, center cell uses corresponding safety up and down according to high level data type
Text is encrypted post package to the type of downlink data and uses logic into downlink data, different types of descending high level data
Channel id is identified.
Above-mentioned descending high level data bag is probably user plane IP packets or non-IP packets, it is also possible to RRC signaling, pin
To different descending high level data types, center cell can carry out corresponding safe handling according to being pre-configured with.
Step 402, center cell send beep-page message to the access point that all terminals may be resident, and are carried in beep-page message
Terminal iidentification.Wherein, terminal iidentification is by the chain of command function distribution of center cell when terminal initial accesses.
Step 403, terminal are attempted to receive beep-page message in wave point, and are sentenced according to carried terminal mark in beep-page message
Whether the disconnected beep-page message is to be directed to itself.If beep-page message is to be directed to itself, terminal initiating random access procedure, and
Carried terminal identifies in random access procedure.
Step 404, access point send terminal location instruction to center cell, wherein, terminal location instruction carried terminal mark
Know.
After step 405, center cell determine the transfer point that terminal is currently resident according to step 404, by downlink data and end
