Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
First carrying in various embodiments of the present invention is meant the carrying that needs to switch transmission path (promptly switching to the object transmission path from former transmission path); For example; ENB confirms that some or a plurality of carryings need switch transmission path, then above-mentionedly one or morely is carried as first and carries.Optional, first carrying can be two-way carrying, also can be downlink bearing.In addition, the address that is carried on the eNB side in the various embodiments of the present invention and comprise the IP address (Transport LayerAddress) of this terminal point in the end address of GW side can also comprise Tunnel Identifier (GTP-TEID) information of carrying.
As shown in Figure 1, one embodiment of the present of invention provide a kind of bearing processing method, comprise the steps.
Step 110, eNB are to MME transmit path handoff request (Path Switch Request) message; The sign that this path handoff request message is carried one or more UE; The sign, above-mentioned first that first of above-mentioned UE carries is carried on the end address of eNB side; And indication information, this indication information is used to indicate whether to allow to discharge the carrying that this path handoff request message is not carried bearing identification.
In this step, the carrying that this path handoff request message is not carried bearing identification comprise first all of UE under carrying carry in, the carrying of not carrying bearing identification of this path handoff request message.Also promptly this indication information is the message-level parameter, and is effective to all UE that the message of carrying this indication information relates to.Optional; This indication information is an enumeration type; For example; Enumerated value Non-included E-RABs not Released representes not allow to discharge the carrying that the message of carrying this indication information is not carried bearing identification, and enumerated value Non-included E-RABs Released representes to allow to discharge the carrying that the message of carrying this indication information is not carried bearing identification.Indication information also can be Boolean type or integer; For example True or 1 expression do not allow to discharge the carrying that the message of carrying this indication information is not carried bearing identification; False or 0 or the field of indication information be empty, the then expression message that allows release to carry this indication information carrying of not carrying bearing identification.
Optional, path handoff request message is carried the sign (eNB UE S1AP ID) of one or more UE, the carrying tabulation (E-RAB To Be Switched) that the sign of each UE is corresponding, and indication information.Wherein, Each carries sign and the end address of the above-mentioned eNB of being carried on side that needs that tabulation comprises this UE switch the carrying of transmission path; Be that eNB is the end address of the eNB side of above-mentioned carrying distribution, adopt the end address of this eNB side when above-mentioned carrying switches to the object transmission path.
Suppose that eNB confirms that one or more carryings of a UE need switch transmission path; Then eNB is the end address that carrying that the needs of this UE switch transmission path distributes the eNB side; ENB is that the end address of the different bearer of this UE eNB side of distributing maybe be identical, also maybe be different.If two carryings have been assigned with the end address of different e NB side, then these two carryings object transmission path that will switch to is different.Optional, the end address of the sign of the carrying that eNB sends and the eNB side of transmission is for concern one to one, the quantity of the sign of promptly carrying is identical with the quantity of end address.
Supposing needs to switch the carrying of transmission path except that above-mentioned; Other carryings of above-mentioned UE all need be retained in former transmission path; Then eNB in the path handoff request message do not carry the sign that these need be retained in the carrying of former transmission path, and indication information is set to indicate and does not allow to discharge the carrying that the message of carrying this indication information is not carried bearing identification.
Supposing needs to switch the carrying of transmission path except that above-mentioned; Other of above-mentioned UE carry all to be needed to discharge; Then eNB in the path handoff request message do not carry the sign of these carryings that need discharge, and indication information is set to indicate and allows to discharge the carrying that the message of carrying this indication information is not carried bearing identification.
In this step, the sign of UE can be the sign of UE in the eNB side, also to be eNB distribute for this UE and with other other signs of UE phase region; This sign is applicable to that eNB and MME distinguish UE when doing inter-process in the S1 interface transmission information; If this sign also is applicable to GW, then MME can adopt this sign to communicate by letter with GW, otherwise; MME can convert this sign into GW discernible sign, does not limit here.Perhaps, the sign of this UE is the general identifications of UE, promptly is not limited to eNB and MME and uses when doing inter-process in the S1 interface transmission information.
The end address that the sign and above-mentioned first that step 120, MME carry first of the sign of the UE that receives, above-mentioned UE is carried on the eNB side sends to GW, and determines whether the carrying that release way handoff request message is not carried bearing identification according to the indication information that receives.
For example, the indication information that MME receives is enumerated value Non-included E-RABs Released, and then MME can confirm the carrying that eNB allows release way handoff request message not carry bearing identification.Further, the MME release way handoff request message carrying of not carrying bearing identification.And for example, the indication information that MME receives is enumerated value Non-included E-RABs not Released, and then MME can confirm the carrying that eNB does not allow release way handoff request message not carry bearing identification.Further, MME carrying that path handoff request message is not carried bearing identification is retained in former transmission path.
In this step, MME also possibly judge self whether to allow to discharge the carrying that the message of carrying this indication information is not carried according to information such as resource situations, rather than the indication of directly accepting eNB.If the judged result of MME is different with the implication of the indication information that eNB sends; MME can switch the carrying that request message do not carry bearing identification and processes according to the judged result of self footpath of satisfying the need; That is to say the condition that MME judges self indication information that eNB sends as triggering.For example; Being carried as that the indication of indication information that MME receives does not allow to discharge carried X, carries Y and carried Z; But MME judges and can be retained in former transmission path with carrying X; Need to discharge and carry Y and carry Z, then MME will carry X and be retained in former transmission path, and initiate the load bearing deactivation process with releasing bearing Y and carrying Z.
Optional, shown in Fig. 1 step 120, the end address that the sign and above-mentioned first that MME carries first of the sign of UE, above-mentioned UE is carried on the eNB side is carried at the datum plane that sends to GW and upgrades in request (Modify Bearer Request) message.For example, the end address that is carried on the eNB side can take the S1 eNodeB F-TEID field in this datum plane update inquiry information.
If first is carried as two-way carrying; Then GW preserved first be carried on eNB side and GW side former end address; Therefore, GW can with first be carried on the eNB side former end address be revised as receive first be carried on the end address of eNB side, and be first to carry the new end address of distributing the GW side; After first carrying switches to the object transmission path, with the new end address that adopts above-mentioned GW side.
If first is carried as downlink bearing; Then GW preserved first be carried on the eNB side former end address; And first carry the corresponding up former end address that is carried on the GW side with this; Therefore, GW can with first be carried on the eNB side former end address be revised as receive first be carried on the eNB side end address.GW also will switch to the object transmission path from former transmission path with the corresponding up carrying of first carrying in this step; Be the new end address of distributing the GW side with the corresponding up carrying of first carrying; With first carry after corresponding up carrying switches to the object transmission path, with the new end address that adopts above-mentioned GW side.
Optional, GW before the new end address of distributing the GW side, earlier according to receive first be carried on the eNB side end address confirm first carries whether needs switch transmission path, if, the new end address of reallocation GW side.For example, GW judge receive first be carried on the end address place of eNB side address field and GW preserved first to be carried on the address field at former end address place of eNB side different, then GW confirms that first carrying need the switching transmission path.If first is carried as two-way carrying; Then GW is the new end address that first carrying distributes the GW side; Adopt after carry switching transmission path for first, the address field at the new end address place of this GW side and GW preserved first be carried on the GW side the address field that belongs to of former end address different.If first is carried as downlink bearing; Then GW confirms also need switch transmission path with the corresponding up carrying of first carrying; And be the new end address of distributing the GW side with the corresponding up carrying of first carrying; After carrying corresponding up carrying switching transmission path with first, adopt, the address field at the new end address place of this GW side address field with the former end address place corresponding up GW of the being carried on side of first carrying that preserved with GW is different.
It will be appreciated by those skilled in the art that, the GW in this step accomplish with PDN-GW mutual after, carry first and to switch to the object transmission path from former transmission path.Wherein, The GW that comprises alternately of GW and PDN-GW sends datum plane renewal request (Modify Bearer Request) message and receives datum plane renewal response (Modify Bearer Response) message that PDN-GW sends to PDN-GW; Said process can repeat no more referring to prior art here.
Need to prove; Present embodiment will receive first of bearing identification with GW and carry that to switch to the object transmission path from former transmission path be that example describes; In fact; GW can judge also which (for example judging according to resource situation or other factors) agreed and carry to be switched transmission path, and the carrying of agreeing to switch transmission path handover success whether.This step successfully elaborates first carrying that all receive bearing identification to GW with subsequent step from the situation that former transmission path switches to the object transmission path; Further; If first among the step 110-130 is carried as two-way carrying, then carry out following step 140-150.If first among the step 110-130 is carried as downlink bearing, execution in step 140 '-150 ' (Fig. 1 is not shown) then.If GW agrees part first carrying is switched to the object transmission path from former transmission path; Perhaps GW successfully carries part first and switches to the object transmission path from former transmission path; Then GW can send the above-mentioned part first of GW to eNB through MME and carry relevant information; The sign of for example carrying, the sign of carrying affiliated UE and GW carry the new end address of the GW side of distribution for this, and do not send the relevant information of first carrying that the GW refusal switches transmission path or the failure of switching transmission path.Certainly, GW also can send the relevant information of that part of first carrying that refusal switches transmission path.For example, the sign of carrying, the sign of carrying affiliated UE, and refusal switches transmission path or switches the indication (or cause value) of transmission path failure.And for example, the sign of the sign of carrying, the UE under carrying and be carried on the former end address of GW side.Optional, above-mentioned information can be carried at the datum plane that GW sends to MME and upgrade response message, and MME sends in the path switching response message of eNB, and which carries and switches the transmission path failure with notice eNB.Under the situation that GW successful switch part first is carried, eNB can switch to the object transmission path from former transmission path with this part first carrying, and back literary composition repeats no more.
Step 140-150, GW are through the sign of MME with UE, and the end address (being that GW is the new end address of the GW side of the first carrying distribution) that the sign and above-mentioned first that first of above-mentioned UE carries is carried on the GW side sends to eNB.
Optional, shown in the step 140-150 among Fig. 1, GW is the sign of above-mentioned UE, the sign that first of above-mentioned UE carries, above-mentioned this first be carried on the GW side end address be carried at datum plane and upgrade in response (Modify Bearer Response) message.Optional, this first be carried on the GW side end address can take this datum plane and upgrade the S1 SGW F-TEID field in response message.MME is with the sign of above-mentioned UE, and the end address that the sign and above-mentioned first that first of above-mentioned UE carries is carried on the GW side is carried in path handoff response (the Path Switch Response) message.
Step 140 '-150 ', GW are through the sign of MME with UE; First of above-mentioned UE carries the sign of corresponding up carrying and the end address of the corresponding up GW of the being carried on side of above-mentioned first carrying (being that GW is the new end address of the GW side of the first carrying distribution) sends to eNB.Optional, the information that GW sends to MME can be carried in the datum plane renewal response message, and the information that MME sends to eNB can be carried in the switching response message of path.
If first is carried as two-way carrying; Then eNB preserved first be carried on eNB side and GW side former end address; Therefore; ENB can with first be carried on the eNB side former end address be revised as and send to the end address that first of MME is carried on the eNB side, and with first be carried on the GW side former end address be revised as receive first be carried on the GW side end address.Further, eNB carries after former transmission path switches to the object transmission path first, and eNB and GW carry out the transmission of first data carried by data on the transmission path after the switching (being above-mentioned object transmission path).
If first is carried as downlink bearing; Then eNB preserved first be carried on the eNB side former end address; And first carry the corresponding up former end address that is carried on the GW side with this; Therefore, eNB can with first be carried on the eNB side former end address be revised as and send to the end address that first of MME is carried on the eNB side.ENB also in this step will with first carry corresponding up carrying and switch to the object transmission path from former transmission path, that is: will with first carry the corresponding up GW of being carried on side former end address be revised as receive with first carry the corresponding up GW of being carried on side end address.Further, eNB accomplish first carry and with first carry corresponding up carrying transmission path switch to after, eNB and GW carry out first and carry and first carry corresponding up data carried by data and transmit on the transmission path after the switching.
In the present embodiment; Can make all or part of carrying of one or more UE switch to another transmission path between this eNB and this GW by a transmission path between eNB and the GW; And all or part of carrying that need not switch transmission path is retained in former transmission path; Discharged the unusual problem of business appearance that causes UE irrelevantly thereby avoid carrying, guaranteed the communication quality of UE.
A kind of bearing processing method that an alternative embodiment of the invention provides comprises step 210-260.Wherein, the step 110-120 in step 210-220 and the foregoing description has any different, and the option of other steps is described and can be repeated no more referring to the foregoing description here with waiting for example.Introduce the difference of the step 210-220 and the step 110-120 of present embodiment below in detail.
In the step 210 in the present embodiment; ENB transmit path handoff request message; The sign that this path handoff request message is carried one or more UE, the sign, above-mentioned first that first of above-mentioned UE carries is carried on the end address of eNB side, and at least one indication information; Wherein, First carrying is meant the carrying that needs to switch transmission path, and each indication information is corresponding with the sign of a UE, is used for indicating whether to allow to discharge the carrying that all carry, this path handoff request message is not carried bearing identification of the UE that belongs to corresponding with this indication information.Indication information in the present embodiment is a UE level parameter, and is promptly only effective to the UE corresponding with this indication information.For example, indication information is carried in the sign information corresponding unit with UE.Optional; If the sign of certain UE is indication information corresponding with it not; Then can be considered indication information is default value, during all that are defaulted as promptly that permission (or not allowing) discharges this UE are carried, this carries the message of indication information or the carrying that information unit does not carry.The adoptable information type of indication information in this step has multiple, and first carries and possibly repeat no more for two-way carrying or downlink bearing here.
In the step 220 of present embodiment; The end address that the sign and above-mentioned first that MME carries first of the sign of the UE that receives, above-mentioned UE is carried on the eNB side sends to GW, and determine whether to discharge in the carrying of each UE according to the indication information that receives, carrying that path handoff request message is not carried bearing identification.Optional, MME judges self whether to allow to discharge the carrying that the message of carrying this indication information is not carried bearing identification according to information such as resource situations, rather than directly accepts the indication of eNB.
For example; In step 210; The sign of the UE that eNB sends comprises the sign of UE1 and the sign of UE2, and eNB sends two indication informations, wherein; The indication information corresponding indication with UE1 allow to discharge this UE all carry in, the carrying of not carrying bearing identification of path handoff request message, and the carrying that the indication information corresponding with UE2 indication does not allow to discharge in all carryings of this UE, this path handoff request is not carried bearing identification.Then in step 220, MME confirm to discharge UE1 all carry in, the carrying of not carrying bearing identification of path handoff request message, during all that do not discharge UE2 are carried, the carrying of not carrying bearing identification of path handoff request message.
In the present embodiment; Can make all or part of carrying of one or more UE switch to another transmission path between this eNB and this GW by a transmission path between eNB and the GW; And all or part of carrying that need not switch transmission path is retained in former transmission path; Discharged the unusual problem of business appearance that causes UE irrelevantly thereby avoid carrying, guaranteed the communication quality of UE.
A kind of processing bearing processing method that an alternative embodiment of the invention provides comprises step 310-360.Wherein, the step 310-320 in step 310-320 and the foregoing description has any different, and the option of other steps is described and can be repeated no more referring to the foregoing description here with waiting for example.Introduce the difference of the step 310-320 and the step 110-120 of present embodiment below in detail.
In the step 310 in the present embodiment; ENB transmit path handoff request message, the sign that this path handoff request message is carried one or more UE, the sign, above-mentioned first that first of above-mentioned UE carries is carried on the end address of eNB side; Sign and at least one indication information that second of above-mentioned UE carries; Wherein, first is carried as the carrying that needs to switch transmission path, and second is carried as the carrying that need not switch transmission path and not allow to discharge; Each indication information is corresponding with one second sign of carrying, and is used to indicate do not allow to discharge the carrying corresponding with this indication information.Indication information in the present embodiment is to carry the level parameter, and is promptly only effective to the carrying corresponding with this indication information.For example, indication information be carried at one second sign information corresponding unit that carries in, be used for indication and do not allow to discharge this carrying.Optional; If eNB has also sent the sign that the 3rd of one or more UE carry; The 3rd is carried as the carrying that need not switch transmission path and allow to discharge, and then eNB can also send with the 3rd and carry corresponding indication information, is used for indication and allows to discharge this carrying.The adoptable information type of indication information in this step has multiple, and first carries and possibly repeat no more for two-way carrying or downlink bearing here.
In the step 320 of present embodiment; The end address that the sign and above-mentioned first that MME carries first of the sign of the UE that receives, above-mentioned UE is carried on the eNB side sends to GW; And confirm according to the indication information that receives which carrying is retained in former transmission path (for example corresponding with indication information second carry), and which discharges carry (the 3rd for example corresponding carrying) with indication information.Optional, MME judges self whether to allow certain carrying is retained in former transmission path according to information such as resource situations, perhaps discharges certain and carries, rather than the indication of directly accepting eNB.
For example, in step 310, the sign of the carrying that eNB sends comprises: the sign of carry M, carrying N and carrying P.Wherein, carrying M is first carrying, and eNB does not send the corresponding indication information with this carrying M.Carrying N is second carrying, and eNB sends with this and carries the corresponding indication information of N, and this indication information indication does not allow this carrying of release N.Carrying P is the 3rd carrying, and eNB sends with this and carries the corresponding indication information of P, and this indication information indication allows to discharge should carry P.Then in step 320, MME will carry the sign of the UE under the M, sign and this carrying M that carries M sends to GW in the end address of eNB side, not releasing bearing N and will carry N and be retained in former transmission path, and releasing bearing P.
