Step 202, relay base station equipment utilization relay base station equipment MTU value determination burst size.
In the embodiment of the present invention, the process of relay base station equipment utilization relay base station equipment MTU value determination burst size, specifically includes but not limited to as under type:
; Wherein, N is positive integer,
represent and round downwards.Such as, when burst size requirements is the integral multiple of 8, then the value of N is 8.
Step 203, relay base station equipment utilization burst size carries out burst process to uplink message.
In the embodiment of the present invention, this uplink message specifically includes but not limited to: uplink business data message or uplink signaling data message or upstream operation maintenance packet.For convenience of description, in subsequent process, be treated to example to carry out burst to uplink business data message, for the processing mode of uplink signaling data message and upstream operation maintenance packet, similar with the processing mode of uplink business data message, do not repeat them here.
The MTU value (i.e. the MTU value of UE and target service server negotiate) supposing transmission path is 1500 bytes, then the length of uplink business data message that UE sends is 1500 bytes.Uplink business data message is after arrival relay base station equipment, and relay base station equipment needs to add IP+UDP+GTPU head in uplink business data message, and totally 36 bytes, now namely relay base station equipment carry out Fragmentation.
Considering that relay base station equipment is follow-up also needs for uplink business data message adds the tunnel head be made up of IP+UDP, totally 28 bytes, and uplink business data message is after arrival DeNB, DeNB also needs to add IP+UDP+GTPU head in uplink business data message, totally 36 bytes.In order to ensure that the uplink business data message after burst can not burst again after adding IP+UDP+GTPU head by DeNB, relay base station equipment is when carrying out Fragmentation, utilize the MTU value of transmission path, to be added to the tunnel head length in message, to be added to the data head length in message, determine relay base station equipment MTU value.
Concrete, relay base station equipment can determine that relay base station equipment MTU value (Relay_eNB_MTU) specifically comprises: MTU value (UE_SERVER_MTU, the i.e. MTU value of UE and the target service server negotiate) ﹣ of transmission path to be added to tunnel head length (TUNNEL_HEADER_LEN) ﹣ in message to be added to the data head length (Donor_GTPU_HEADER_LEN) in message.
Wherein, relay base station equipment MTU value refers to: the numerical value of the MTU configured when relay base station equipment burst, namely burst process can be carried out when uplink business data message exceedes this MTU, this relay base station equipment MTU is not the MTU of the uplink business data message that relay base station equipment sends, and this relay base station equipment MTU needs to increase tunnel head 28 byte on this basis.Referring to be added to the tunnel head length in message: at relay base station equipment side, need to add tunnel head again after burst, is IP+UDP form, totally 28 bytes.Refer to be added to the data head length in message: in DeNB side, need the IP+UDP+GTPU head added, totally 36 bytes.After calculating, relay base station equipment MTU value is 1436.
Further, based on relay base station equipment MTU value,
; Wherein, N is positive integer 8.Wherein, point leaf length when burst size of packet segment is relay base station equipment burst, IP head length in reserve can configure according to actual needs, as being configured to 60 bytes.Because burst size requirements is the integral multiple of 8, therefore

Compared with prior art, the embodiment of the present invention at least has the following advantages: in the embodiment of the present invention, by adopting the technology of pre-burst, reasonably configure the MTU value of relay base station equipment and tunnel server simultaneously, thus effectively can evade the generation of message secondary burst, and reduce the number of times of message fragment, reach the object promoting network transmission efficiency, and the difficulty of Message processing can be reduced.Because tunnel server does not need the message after assembling twice burst, thus the complexity of tunnel server process can be reduced.
Embodiment two
Take Fig. 1 as the application scenarios schematic diagram of the embodiment of the present invention, the embodiment of the present invention two provides a kind of method of burst process, and as shown in Figure 3, the method for this burst process comprises the following steps:
Step 301, tunnel server utilizes the MTU value of transmission path, to be added to the tunnel head length in message, to be added to the data head length in message, determines tunnel server MTU value.
In the embodiment of the present invention, tunnel server utilize transmission path MTU value, to be added to the tunnel head length in message, to be added to the data head length in message, determine the process of tunnel server MTU value, include but not limited to as under type: tunnel server determination tunnel server MTU value is: the MTU value ﹣ of transmission path to be added to the tunnel head length ﹣ in message to be added to the data head length in message.
In the embodiment of the present invention, specifically should include but not limited to be added to the tunnel head length in message: the length of the tunnel head become with UDP head group by IP head; Specifically should include but not limited to be added to the data head length in message: the length of the data head become with GTPU head group by IP head, UDP head.
Step 302, tunnel server utilizes tunnel server MTU value determination burst size.
In the embodiment of the present invention, tunnel server utilizes the process of tunnel server MTU value determination burst size, specifically can include but not limited to as under type:
; Wherein, N is positive integer,
represent and round downwards.Such as, when burst size requirements is the integral multiple of 8, then the value of N is 8.
Step 303, tunnel server utilizes burst size to carry out burst process to downlink message.
In the embodiment of the present invention, this downlink message specifically includes but not limited to: downlink service data message or downlink signaling data message or downstream operation maintenance packet.For convenience of description, in subsequent process, be treated to example to carry out burst to downlink service data message, for the processing mode of downlink signaling data message and downstream operation maintenance packet, similar with the processing mode of downlink service data message, do not repeat them here.
The MTU value (i.e. the MTU value of UE and target service server negotiate) supposing transmission path is 1500 bytes, then the length of downlink service data message that target service server sends is 1500 bytes.Downlink service data message is after arrival SGW, and SGW needs in this downlink service data message, to add IP+UDP+GTPU head, totally 36 bytes, and carries out first time Fragmentation, and the downlink service data message after burst is sent to tunnel server.Tunnel server, after receiving downlink service data message, is recombinated to downlink service data message, and to the downlink service data message burst again after restructuring.
Considering that tunnel server is follow-up also needs for downlink service data message adds the tunnel head be made up of IP+UDP, totally 28 bytes, and downlink service data message is after arrival SGW, SGW also needs to add IP+UDP+GTPU head in downlink service data message, totally 36 bytes.In order to ensure that the downlink service data message after burst can not burst again after adding IP+UDP+GTPU head by SGW, tunnel server is when carrying out Fragmentation, need to utilize the MTU value of transmission path, to be added to the tunnel head length in message, to be added to the data head length in message, determine tunnel server MTU value.
Concrete, tunnel server can determine that tunnel server MTU value (Tunnel_Svr_MTU) specifically comprises: MTU value (UE_SERVER_MTU, the i.e. MTU value of UE and the target service server negotiate) ﹣ of transmission path to be added to tunnel head length (TUNNEL_HEADER_LEN) ﹣ in message to be added to the data head length (Donor_GTPU_HEADER_LEN) in message.
Wherein, tunnel server MTU value refers to: the numerical value of the MTU configured when tunnel server burst, namely burst process can be carried out when downlink business data message exceedes this MTU, this tunnel server MTU value is not the MTU of the downlink service data message that tunnel server sends, and this tunnel server MTU value needs to increase tunnel head 28 byte on this basis.Referring to be added to the tunnel head length in message: in tunnel server side, need to add tunnel head again after burst, is IP+UDP form, totally 28 bytes.Refer to be added to the data head length in message: in SGW side, need the IP+UDP+GTPU head again added, totally 36 bytes.After calculating, tunnel server MTU value is 1436.
Further, based on tunnel server MTU value, then
; Wherein, N is positive integer 8.Wherein, point leaf length when burst size of packet segment is tunnel server burst, and IP head length in reserve can configure according to actual needs, as being configured to 60 bytes.Because burst size requirements is the integral multiple of 8, therefore
; Wherein, N is positive integer 8.After calculating, then the burst size of packet segment can be 1376.
Further, tunnel server utilizes the burst size of packet segment to carry out burst process to downlink service data message, and adds the tunnel head be made up of IP+UDP, and the length of the actual downlink service data message sent of this tunnel server is 1464 bytes.Based on this, when the downlink service data message after burst is after arrival SGW, SGW can add IP+UDP+GTPU head in the downlink service data message after the burst received.And the downlink service data message increased after IP+UDP+GTPU head is 1500 bytes, so downlink service data message can not burst again.Downlink service data message is when being sent to DeNB, and DeNB can't perform the function of separating burst, but directly takes off the IP+UDP+GTPU head added by SGW second time, and downlink service data message is sent to relay base station equipment.After downlink service data message is sent to relay base station equipment, relay base station equipment performs the operation of separating burst.Further, relay base station equipment takes off the IP+UDP+GTPU head that the tunnel head that added by tunnel server and SGW first time add, and downlink service data message sends to UE the most at last.
Compared with prior art, the embodiment of the present invention at least has the following advantages: in the embodiment of the present invention, by adopting the technology of pre-burst, reasonably configure the MTU value of relay base station equipment and tunnel server simultaneously, thus effectively can evade the generation of message secondary burst, and reduce the number of times of message fragment, reach the object promoting network transmission efficiency, and the difficulty of Message processing can be reduced.Because tunnel server does not need the message after assembling twice burst, thus the complexity of tunnel server process can be reduced.
