In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only embodiment of the invention a part of, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.

The embodiment of the present application base station using the agent IP address bound with the UE as UE IP address.Acted on behalf of using TCP/IP, UE is only provided using related function, and transmission control is placed on base station with network control.Only need to set up a unified carrying between base station and PGW（That is common carrier, it is not necessary to set up a carrying for each UE respectively）, a large amount of M2M equipment are transmitted by base station in common carrier, and so middle TCP releases process needs two Correspondent Nodes of UE and Server compared with prior art Being shaken hands by 4 times to discharge, only need to set up a unified carrying between the embodiment of the present application base station and PGW, a large amount of M2M equipment are transmitted by acting on behalf of in unified carrying, can thus TCP be avoided to discharge, the complicated Signalling exchange that carrying is set up for each UE is saved, the transmission effect for improving M2M business is described in further detail with reference to Figure of description to the embodiment of the present application.

As shown in Fig. 2 the system of the transmission data of the embodiment of the present application one includes：First base station 10 and PGW

11。

First base station 10, belong to for being received by the radio bearer between UE after the first data of the UE, using the agent IP address bound with the UE as UE IP address, first data are encapsulated using TCP/IP and obtain the second data, second data are sent to the PGW by the common carrier between the PGW, wherein the common carrier is used for the second data for transmitting multiple UE；By the common carrier between the PGW receive from the PGW include with the UE bind agent IP address the 3rd data after, 3rd data are decapsulated using TCP/IP and obtain the 4th data, the 4th data are sent to the UE by the radio bearer between the UE.

PGW 11, is used for receiving the first base station by the common carrier between first base station

TCP/IP encapsulates the second data obtained after the first data for belonging to UE, and send second data to outer net, wherein described first data are the data that the first base station is received by the radio bearer between UE, the source IP address that the common carrier is used in the second data for transmitting multiple UE, second data is the agent IP address bound with the UE；After the 3rd data from the outer net are received, it is determined that the common carrier in common carrier between the first base station with the purpose IP address binding in the 3rd data, and pass through the common carrier of determination and send the 3rd data.

The outer net of the embodiment of the present application can be APP (application, application）Server, can also be other equipment for being in outer net.

For UE, it is not necessary to know the agent IP address with oneself binding, it is only necessary to which the first data are sent into base station, by base station according to the agent IP address bound with UE, the first data are encapsulated using TCP/IP and obtain the second data；After the 3rd data from PGW are received, the 3rd data are decapsulated using TCP/IP and obtain the 4th data, are then sent to the 4th data and the agent IP address bound in the 3rd data UE。

Wherein, UE can also be bound except being bound with IP address with TCP port number.

The agent IP address bound with UE is as source IP address, and same purpose IP address, source tcp port number and purpose TCP port number encapsulate to form the second data together with the first data.Source IP address be for UE distribute agent IP address, source tcp port number can for distinguish UE or distinguish UE different application；Purpose IP address is the IP address with the server of UE communication, and purpose TCP port number is the application service mark of server.

In force, the embodiment of the present application can only be bound with an agent IP address with a UE（One IP address of prior art is bound with a UE）.Because the embodiment of the present application is bound using agent IP address with UE, base station is no longer transparent transmission, and base station is responsible for binding IP address and UE so that an agent IP address can be bound with the UE of multiple access base stations.If an agent IP address only can be bound with a UE, a UE can be recognized by an agent IP address;If an agent IP address is bound with multiple UE, a UE can be recognized jointly by TCP port number and agent IP address.

Due to the limited amount of IP address, and the increase of UE quantity is rapid, if an agent IP address is bound with multiple UE, can increase the UE of binding agent IP address quantity, make up the influence that the limited amount of IP address is brought to UE quantity increases.

For PGW, it is necessary to which the common carrier by the UE agent IP address bound and between first base station is bound, after the second data are received by common carrier, outer net is sent to；After the 3rd data from outer net are received, by sending the 3rd data with the common carrier that the purpose IP address in the 3rd data is bound.

Wherein, first base station is by the radio bearer between the UE, after the upstream data bag that the UE is received first, is the UE binding agents IP address.

The agent IP address of the embodiment of the present application can be safeguarded by each base station, can also be safeguarded by PGW and be notified, to each base station, to be introduced separately below.

Mode one, each base station maintenance agent IP address.

Specifically, first base station is received after the upstream data bag of the UE first by the radio bearer between the UE, agent IP address is selected from reserved agent IP address, and choosing is bound for the UE The agent IP address selected.

Wherein, first base station can reserve a part of IP address as IP address, first base station is acted on behalf of for the UE of M2M business can select agent IP address when needing for UE binding agent IP address from reserved agent IP address.

If agent IP address is only bound with a UE, first base station select not with it is any

The agent IP address of UE bindings；

If an agent IP address is bound with multiple UE, at this moment an agent IP address and a TCP port bind a UE, due to TCP port limited amount（Current TCP port is 65536, which part can be used for binding UE), if an agent IP address and all available TCP ports have all bound UE, then the agent IP address can not temporarily be used, so first base station may be selected that the agent IP address used when selection.

First base station, by the common carrier between PGW, the synchronization message for including the agent IP address is sent to PGW after the agent IP address of selection is bound for the UE；

Accordingly, PGW is by the common carrier between the first base station, after the synchronization message from the first base station is detected, and the agent IP address in the common carrier between the first base station and the synchronization message is bound.

In force, if first base station can not select agent IP address from reserved agent IP address, if such as one agent IP address is only bound with a UE, currently without the agent IP address do not bound with UE；If an agent IP address is bound with multiple UE, currently without available IP addresses, then first base station sends the request for obtaining agent IP address to the PGW；

Accordingly, PGW selects agent IP address after the request of the acquisition agent IP address from the first base station is received, and bound the common carrier between the first base station and the agent IP address chosen, and the agent IP address of selection is sent to the first base station.

In force, PGW is that an IP address section is reserved in each base station, is acted as agent for corresponding base station.

Mode two, PGW safeguard agent IP address.

Specifically, first base station receives the upper of the UE first by the radio bearer between the UE After row packet, the request for obtaining agent IP address is sent to the PGW, and the agent IP address from the PGW received is bound for the UE；

For mode two, because PGW is not aware that agent IP address and UE binding relationship, only know the corresponding relation of agent IP address and public load, if so an agent IP address is bound with multiple UE, PGW is not aware that whether the agent IP address for having bound common carrier can use, first base station can only be inquired when needing and distributing and bound the agent IP address of common carrier, whether the agent IP address can use.Based on this, for mode two, preferably one agent IP address is only bound with a UE.

Except the process of above-mentioned binding agent IP address, the embodiment of the present application additionally provides the process of release binding.

Specifically, first base station is after release conditions are met, it is determined that needing to discharge the radio bearer between the UE, the agent IP address bound with the UE is notified into the PGW by release message, and discharge the UE and the agent IP address binding relationship；

Accordingly, PGW is received by the common carrier with first base station after the release message from first base station, the agent IP address included in release message and the binding relationship with the common carrier of first base station.

One kind that release conditions include but is not limited in following condition：

UE does not have data transfer within a period of time（Such as inactivity timer（Inactive timer) time-out）；

UE is switched on other base stations, and changes agent network element；

Receive the connection release message with the server triggers of UE communication.

PGW can also discharge binding relationship automatically.

Specifically, first base station need release binding relationship when, it is necessary to outer net carry out 4-Way Handshake（Referring specifically to step 910 ~ step 913 in Fig. 9), the PGW can be in the common carrier after receiving four-way handshake messages between release and the first base station and the binding relationship for the agent IP address for needing release（Need The agent IP address to be discharged can be by determining in the message of 4-Way Handshake）；

That is, the PGW is completed between the first base station and outer net for after release the shaking hands of binding relationship, discharging the binding relationship the common carrier between the first base station and the agent IP address for needing release.

For aforesaid way one, if an agent IP address can only be bound with a UE, the first base station it is determined that need discharge and the UE between radio bearer after, can also reclaim it is described act on behalf of IP address so that the agent IP address can bind other UE.

Specific way of recycling has a lot, such as inside of base station can safeguard a table be used for store the agent IP address table that can distribute, if an agent IP address has bound UE, then the agent IP address is deleted from the table, if necessary to reclaim an agent IP address, then the agent IP address is added in the list item；

Also such as base station is the mark that each agent IP address sets 1 bit, such as 0 represents to use, 1 represents to use, if then an agent IP address has bound UE, the mark for acting on behalf of IP address is then set to 1, if necessary to reclaim an agent IP address, then the mark of the agent IP address is set to 0.

For aforesaid way two, if an agent IP address can only be bound with a UE, the PGW is after the notice of the release comprising the agent IP address from the first base station is received, the agent IP address can also be reclaimed, so that the agent IP address can bind other UE.

Specific way of recycling has a lot, can be safeguarded inside such as PGW a table be used for store the agent IP address that can distribute, if an agent IP address has been bound public 7 and carried, then the agent IP address is deleted from the table, if necessary to reclaim an agent IP address, then the agent IP address is added in the list item；

Also such as PGW is the mark that each agent IP address sets 1 bit, such as 0 represents to use, 1 represents to use, if then an agent IP address has bound common carrier, the mark of the agent IP address is then set to 1, if necessary to reclaim an agent IP address, then the mark for acting on behalf of IP address is set to 0.

In force, UE can switch over operation.For UE switching, the embodiment of the present application has two kinds Processing mode：One is to change the base station newly accessed of agent network element, i.e. UE as network element, is that UE binds new agent IP address, first base station is not involved in UE data transfer；Two be to be changed without agent network element, i.e., the agent IP address bound with the UE is constant, and UE data are all sent by first base station.

Because M2M is only small amount of data reporting service, interaction time is shorter, if changing agent network element in movement is difficult to the continuity of guarantee business, therefore is changed without the continuity that agent network element ensure that business compared to replacing agent network element.

It is introduced separately below.

First, agent network element is changed.

Specifically, first base station is after the UE is switched to the second base station, the agent IP address bound with the UE is notified into the PGW by release message, and discharge the UE and the agent IP address binding relationship；

Accordingly, PGW is after the notice of the release comprising the agent IP address from the first base station is received, the agent IP address of the common carrier binding between release and the first base station.

Except first base station notifies the mode of the PGW, there is a kind of mode for changing agent network element：If the first base station sends the request for obtaining agent IP address to the PGW, and is described

The agent IP address from the PGW that UE bindings are received.Because agent IP address is distributed by PGW, in order to save resource, it will can be notified when changing agent network element by first base station with the UE agent IP address bound to the second base station, so that agent IP address and the UE are bound in the second base station.

Specifically, if the UE is switched to the second base station, the first base station discharges the UE and the agent IP address binding relationship, and will be sent to the second base station with the UE agent IP address bound, so that the agent IP address and the UE are bound in second base station；

Accordingly, the agent IP address and the UE are bound in the second base station, and the modification request for including the agent IP address is sent to PGW；

PGW is after the request of the modification comprising the agent IP address from the second base station is received, the agent IP address of common carrier binding between release and the first base station, the common carrier and the agent IP address between second base station are bound.

First base station, can be with except will be sent to the second base station with the UE agent IP address bound The second base station will be sent to the TCP port number that UE is bound.

2nd, it is changed without agent network element.

If specifically, the UE is switched to the second base station, the first base station sets up the X2 carryings for the UE with second base station；

The first base station by the common carrier between the PGW receive from the PGW include with the UE bind agent IP address the 3rd data after, 3rd data are decapsulated using TCP/IP and obtain the 4th data, the 4th data are sent to second base station by X2 carryings；And

The first base station is after receiving by X2 carryings and belonging to the first data of the UE, source IP address will be used as with the UE agent IP address bound, first data are encapsulated using TCP/IP and obtain the second data, second data are sent to the PGW by the common carrier between the PGW.

Wherein, first base station is set up for after UE X2 carryings, the second base station can be bound X2 carryings with UE, after the data of the UE are received with second base station, is just carried and sent by the UE X2 bound；After data are received by X2 carryings, the UE with the X2 bearing bindings can be sent the data to.

Situation for being changed without agent network element, if the second base station is thought to need to discharge the connection with UE, such as UE is sent without data for a long time, or UE does not have data transfer within a period of time, or UE itself initiates to enter Idle state, then is sent to first base station and carry releasing request for the UE；Accordingly, first base station receive from second base station for the UE carrying releasing request after, release is carried with the X2 for the UE that second base station is set up, and the agent IP address that release is bound with the UE, and the agent IP address bound with the UE by release message is notified into the PGW.

Arrange to give some instances again separately below and the scheme of the application is illustrated.

(one）, eNB uses for the UE reservation agent IP address of M2M business as agency. PGW An IP address section is stayed for each eNB, is acted as agent for eNB, can go to apply for new IP address at PGW after the ip address depletions that eNB is obtained.The binding procedure of carrying is actively completed by PGW, after PGW detects the SYN requests that TCP initiates will the request source IP address, purpose IP address, source port number numbers with carrying with destination slogan and mutually binds, and discharges process also similar.In the case of realizing that no control signaling is participated in, PGW is from the new IP address of chief commander and TCP port number binding/unbinding to common bearer (common carrier, i.e., the carrying between base station）On.This flow it is specific as shown in figure 9, including：

Step 901：Wireless connection is set up between UE and eNB.

Step 902:UE sends upstream data by radio bearer.

Step 903:ENB receive UE transmission upstream data bag, be UE binding agents IP address and

TCP port number.

Step 904:ENB is sent comprising the synchronization request message with the UE agent IP address bound to purpose Server.

Step 905:The PGW pairs of common bearer packet being connected with eNB is filtered, and detects after synchronization request message, actively agent IP address and TCP port number are tied in common carrier, that is, updates PGW traffic flow template.

Step 906:PGW forwards the synchronization request message.

Step 907:APP servers receive the synchronization request message from external network.

Step 908:APP servers carry out response to synchronization request message, complete TCP/IP establishment of connections.

Step 909:When a period of time no data is transmitted, eNB triggering releasing wireless loadings and TCP/IP agencies.

Step 910:ENB sends the connection release request message for including agent IP address by PGW to APP servers（FIN ).

Step 911:APP servers return to response message by PGW to eNB.

Step 912:APP servers send FIN message by PGW to eNB.

Step 913:ENB returns to response message by PGW to APP servers. Step 914:PGW actively discharges traffic flow template and agent IP address and the binding relationship of TCP port number；The binding relationship of PGW releases IP address, TCP port number and common bearer.

Step 915:ENB discharges the wireless connection between UE.

(two）, as UE because quality of wireless channel is deteriorated, it is necessary to when being moved to new eNB, source eNB is difficult to the continuity of guarantee business performing TCP/IP agencies, traditional switch means.Accordingly, it is considered to

M2M is only small amount of data reporting service, and interaction time is shorter, and TCP/IP agencies are changed without in movement, and the X2 Bearer set up between source eNB and target eNB are used to forward data.This flow is specific as shown in Figure 10, including：

ENB uses the process such as step 901 ~ step 908 in Fig. 9 to set up TCP/IP connections.

Step 1001:UE or eNB detect quality of wireless channel and serviced less than the threshold value of service, it is necessary to be moved under new eNB.

Step 1002:Source eNB request targets eNB is that the UE sets up X2 carryings, and the data for transmitting UE between source eNB and target eNB while it is still source eNB to act on behalf of eNB, that is, is acted on behalf of and do not switched in moving process.

Step 1003:Target eNB responses source eNB request.

Step 1004:UE is linked into target eNB and obtains service.

Step 1005:It is inactive that target eNB detects a period of time UE, i.e., no data transfer, determines release wireless connection.

Step 1006:Target eNB request source eNB release X2 Bearer.

Step 1007：Source eNB is released to the TCP/IP agencies of UE foundation.

Step 1008:Source eNB response targets eNB request.

Step 1009:Target eNB releasing wireless loadings.

(three）, there is X2 Bearer between source eNB and target eNB, UE obtains data from target eNB.UE is when needing to again move into new eNB or returning to S-eNB, it is necessary to corresponding interaction.This flow is specifically as shown in figure 11, including：

UE is operated under target eNB, and source eNB is UE TCP/IP agencies, and there is UE special X2 Bearer between source-eNB and target eNB is used to do data forwarding. When UE needs to again move under new eNB, such as new eNB then needs the X2 Bearer between source eNB and target eNB to be moved between source eNB and new eNB, UE accesses new eNB and serviced.

Step 1101：Target eNB carries new eNB cell ID when sending mobile request message to source eNB（cell id ).

Step 1102:Source eNB is addressed to new eNB according to the cell ID, and sending X2 carryings to new eNB sets up request.

Step 1103:New eNB returns to X2 Bearer to source eNB and sets up response.

Step 1104:Source eNB sends release X2 Bearer message to target BS.

UE transmits data after new eNB is accessed by the X2 Bearer between source eNB and new eNB.When UE needs to switch back into source eNB, then need the X2 Bearer releases between source eNB and new eNB, UE and source eNB re-establishes radio bearer.

Step 1105：New eNB carries source eNB cell ID in mobile request message.

Step 1106:The Target cell that source eNB detects switching then discharges the X2 Bearer between new base station when being this cell

Step 1107:Source eNB and UE re-establishes radio bearer.

(four）, in the PGW distribution IP address schemes that provide of the embodiment of the present application, PGW controls address resource, and dynamically distributes can effectively utilize IP address resource.ENB being acted on behalf of when having demand, dynamic requests IP addresses are used as UE agent IP address.Compared to acting on behalf of eNB self-management agent IP address, although adding the signalling interactive process between eNB and PGW, but ip addresses can be allowed to be flowed each other between base station, use and just distributed, a base station is avoided not have ip addresses can use, but there is the situation of much idle address another base station, improves the utilization rate of agent IP address.

The Signalling exchange that eNB self-managements agent IP address is distributed compared to PGW between the scheme reduction eNB and PGW of IP address is acted on behalf of, but a base station can not be avoided not have ip addresses can use, but there is the situation of blunt many idle addresses another base station.

This flow is specifically as shown in figure 12, including：

Step 1201:The wireless connection set up between UE and eNB.

Step 1202:ENB (i.e. agent network elements）Send GTP (GPRS Tunneling Protocol, GPRS Tunnel protocol；GPRS, General Packet Radio Service, GPRS）Ask to PGW, request obtains agent IP address.

Step 1203:PGW distributes one or several IP address and bound to UE, and by the IP address with the common bearer phases between eNB and PGW.

Step 1204:PGW returns to the IP address that eNB can be used for agency.

Step 1205:ENB receives the upstream data from UE, is that TCP/IP connections are acted on behalf of in UE foundation.

Step 1206:When a period of time no data is transmitted, eNB triggering releasing wireless loadings and TCP/IP agencies.

Step 1207：The TCP/IP connections that eNB releases have been set up.

Step 1208:ENB sends release IP address bind request to PGW, and request discharges the IP address and the binding relationship of carrying, discharges IP address resource.

Step 1209 ~ 1210：PGW reclaims the IP address, the binding relationship of release and carrying, and response cNB.

Step 1211:ENB discharges UE radio bearer.

(five）, using PGW distribute IP address scheme, agent network element can be changed when UE is moved between eNB, agent network element can also be changed without.Because IP address is controlled in PGW hands, if IP address can be bundled on new Bearer by changing agent network element when being moved between occurring eNB, that is, the binding relationship between IP addresses and eNB is released.This flow is specifically as shown in figure 13, including：

Step 1301:The UE measurement radio link qualities that service is obtained under S-eNB are less than after the threshold value that can be serviced, that is, are moved to new eNB, i.e. target T-eNB through both sides' negotiation when meeting the condition being switched under new eNB.

Step 1302:Source eNB sends proxy-switching request, and the information such as agent IP address and TCP port number are sent into target eNB.

Step 1303:Target eNB sends bearing modification request after receiving the request of source eNB transmissions to PGW, and the request carries UE identification information and IP address information

Step 1304 ~ step 1305:PGW discharges tying up for the common carrier between the IP address and source base station Determine relation, and the IP address is tied under the common carrier between target BS, while PGW returns to binding success response.

Step 1306:Target eNB returns to proxy-switching response.

Step 1307:UE is linked into target eNB and obtains service.
