Embodiment
In order to solve interface-free resources to be caused present in prior art certain pressure, and influence existing
A kind of sending method of application layer data is provided in the problem of scheduling mechanism, the application following examples,
And it is a kind of can apply this method device.
The sending method of the application layer data of the embodiment of the present application includes herein below：
PDN need to be configured with the IP address of at least one EPC SGI interfaces and/or at least one
ENodeB IP address, for example, PDN wish connection EPC SGI interfaces IP address and/
Or eNodeB IP address.When PDN will send application layer data, by the application layer data with IP
The mode (being referred to as application layer packet) of bag is sent, and purpose IP address is set to EPC SGI
The IP address of interface or eNodeB IP address.
It is initial in system design, consult a particular value between EPC and eNodeB, for example, this is specific
Value can be 0xFFFF.
As shown in Fig. 2 handling processes of the EPC after application layer packet is received is as follows：
Step S101, receives the application layer packet (IP packets) that PDN is sent；
Step S102, whether the purpose IP address for judging the application layer packet received is this EPC's
The IP address of SGI interfaces, if so, then performing step S103, otherwise, performs step S104；
Step S103, encapsulation GTPU (GPRS Tunnelling are wrapped in the application layer data received
Protocol for User Plane, GPRS user planes tunnel protocol) head, and it is sent to what this EPC was managed
All eNodeB in connection status, wherein, TEID (the Terminal Equipment in the GTPU
ID, tunnel termination point identification) value of field is set to particular value, and the particular value is used to indicate that eNodeB should
Application layer packet is broadcast to all on-line UEs that this eNodeB is managed；
In step s 103, due to application layer packet purpose IP address be this EPC SGI interfaces
IP address, so, confirm that the application layer packet needs to be sent to this EPC with broadcast mode and managed
All online (that is, in attachment state) UE under all eNodeB in connection status of reason,
Now, the eNodeB of connection status is in for each managed of this EPC, EPC is in the application
The value that layer data wraps the TEID fields in encapsulation GTPU heads, the GTPU is set to particular value,
For example, 0xFFFF, and the application layer packet (GTPU packets) after encapsulation is connect by S1-U
Mouth is sent to the eNodeB.
Step S104, judges whether the purpose IP address of the application layer packet received is managed by this EPC
The eNodeB of reason IP address, if so, then performing step S105, otherwise, performs step S107；
Step S105, judges that the eNodeB indicated by purpose IP address (for convenience, is designated as
ENodeB1) whether connection status is in, if so, then performing step S106, otherwise, performs step S107；
Step S106, encapsulation GTPU heads are wrapped in the application layer data received, and are sent to eNodeB1,
Wherein, the value of the TEID fields in the GTPU is set to particular value, and the particular value is used to indicate eNodeB
The application layer packet is broadcast to all on-line UEs that this eNodeB is managed；
In step s 106, by the purpose IP address of the application layer packet received is managed by this EPC
The eNodeB1 of reason IP address, also, eNodeB1 is in connection status, so, confirm the application layer
Packet needs to issue all on-line UEs that eNodeB1 is managed with broadcast mode, and now, EPC is at this
The value that application layer data wraps the TEID fields in encapsulation GTPU heads, the GTPU is set to particular value,
Such as 0xFFFF, and the application layer packet after encapsulation is sent to eNodeB1 by S1-U interface.
Step S107, abandons the application layer packet received.
As shown in figure 3, eNodeB is packaged with the processing after the application layer packet of GTPU receiving
Flow is as follows：
Step S201, receives and is packaged with the application layer packet of GTPU；
Step S202, whether the value for judging the TEID fields in the GTPU is particular value, if so,
Step S203 is then performed, otherwise, this flow is exited；
Step S203, the application layer packet received is carried this is sent in broadcast message
All on-line UEs that eNodeB is managed.
In step S203, because the value of the TEID fields in GTPU is particular value, so, really
Recognizing the application layer packet received needs to be broadcasted, now, and eNodeB is by the application layer packet
It is submitted to this eNodeB RRC (Radio Resource Control, wireless heterogeneous networks) layer, RRC
Layer receives the broadcast message for generating and eating dishes without rice or wine after the application layer packet, and the broadcast message of generation is submitted
To user plane so as to the transmission for carrying out eating dishes without rice or wine to broadcast the message by user plane.Broadcast data is carried in broadcast message
Bag sends configured information and carries bit (bit) stream of the application layer packet, wherein, broadcast number
Send configured information is used for indicating whether carry application layer packet in this broadcast message according to bag.
As shown in figure 4, the handling processes of UE upon receiving the broadcast message are as follows：
Step S301, receives broadcast message；
Step S302, judges that the broadcast data packet carried in the broadcast message sends whether configured information indicates
Go out and application layer packet is carried in this broadcast message, application layer is carried in this broadcast message if indicating
Packet, then perform step S303, if indicating without carrying application layer packet in this broadcast message,
Then perform step S304；
Step S303, obtains the application layer packet carried in the broadcast message, and be sent to industry user
Application terminal；
In step S303, UE reads the bit streams that application layer packet is carried in the broadcast message,
And the application layer packet is submitted to this UE application layer, answering for industry user is sent to by application layer
Use terminal.
Step S304, performs the handling process of the broadcast message of prior art, for example, this is broadcast the message
The parameter configuration of middle carrying is to this UE user plane and/or physical layer etc..
When actually implementing, the purpose IP address for the application layer packet that PDN is sent can also be UE
IP address, now, the processing stream of PDN, EPC, eNodeB and base station for application layer packet
Journey is not repeated this referring to prior art, the application.
