Description
Technical field
The present invention relates to a kind of communication technology, relate in particular to a kind of method and system of realizing carrying merging.
Background technology
Along with the communication service development, the application of MBMS business is also more and more wider, people are also high more to the requirement of MBMS quality of service, when UE (user terminal) is in cell edge because of moving, owing to may need to switch in this zone, when switching, need therefore, fluctuate maximum according to the signal of sub-district in the bearing mode of eating dishes without rice or wine to adopt (as PTP carrying or PTM carrying) merger activity sub-district at the signal quality that this regional UE received.
In the prior art, can support the soft handover function when MBMS (BroadCast MultiCast Service) is professional when eating dishes without rice or wine to adopt PTP (point-to-point) carrying, the same user's of different districts descending PTP carrying can realize soft merging.
When the MBMS business when eating dishes without rice or wine to adopt PTM (putting multiple spot) carrying, can support the soft merging of neighbor cell same MBMS business and select to merge that described sub-district belongs to same cell set, and belongs to same RNC (radio network controller).When carrying MBMS was professional, same PDCP (PDCP) and UM RLC (control of Unacknowledged Mode Radio Link) entity were shared in each sub-district in the same cell set.UE (user terminal) receives the same MBMS business from each sub-district PTM carrying, realizes soft merging or select merging according to the UE side that is configured in of RNC.
In order to realize pooling function, UE need know which abutting subdistrict supports the selection of this MBMS business to merge, reach these adjacent sub-districts and carry the PTM RB configuration of this MBMS business, have the RRC message that has MBMS NEIGHBOURING CELL P-T-M RB INFORMATION (the MBMS abutting subdistrict is put the multiple spot beared information) at the chain of command of eating dishes without rice or wine for this reason.When the MBMS activation of service, UE in the sub-district of NEIGHBOURING CELL P-T-M RBINFORMATION indication in according to the signal quality of each sub-district, determine to join the sub-district of selecting in the merging branch, and dynamically adjust each branch according to signal quality.
Yet in above-mentioned prior art, when the PTM carrying was all adopted in all sub-districts in the cell set, this merging method did not have problems.When the PTP carrying was all adopted in each sub-district, this merging method did not have problems yet.When part sub-district in the cell set adopts PTP carrying, part sub-district to adopt the PTM carrying, then there is following point.
Problem 1, network side suppose to consider that neighbor cell merges the gain that brings when giving this sub-district PTM carrying allocating power of this MBMS business of carrying, the power of configuration can be less relatively.Make PTP when carrying when certain adjacent sub-district into by PTM, the selection of this sub-district and this neighbour sub-district merges gain and has not just existed, and causes this sub-district in the coverage effect meeting variation near this neighbour sub-district part; If dynamically adjust the power that this sub-district PTM carries, will make to handle to become complicated according to the bearer types of adjacent sub-district; The adjacent sub-district that has in this adjacent cells of cells adopts PTM to carry simultaneously, and existence merges gain, and the adjacent sub-district that has adopts PTP to carry, and does not have the merging gain, when requiring near the satisfied covering in the adjacent sub-district of some part, then has the wasting of resources near other adjacent sub-districts.
Problem 2, be in type be PTP carry adjacent sub-district UE near this sub-district the time because there is not the soft handover gain of this sub-district PTP carrying, cause UE the time near this sub-district, the transmitting power of adjacent sub-district PTP carrying is bigger than normal, maybe can not satisfy professional qos requirement.
In sum, according to the merging method of prior art, exist coverage effect poor, handle shortcomings such as complexity or transmitting power are bigger.

Description of drawings
Fig. 1 shows the process chart of UE from the free time to the connected state.
Embodiment
Understand and realization the present invention the existing embodiments of the invention of describing in conjunction with the accompanying drawings for the ease of persons skilled in the art.
Basic thought of the present invention is, UE receives from the same MBMS of each sub-district in the Active Set when professional, earlier the signal of PTP carryings all in the Active Set is realized soft merging, the signal of PTM carryings all in the Active Set is realized soft merging or select merging, again the amalgamation result of PTP and the amalgamation result of PTM are selected to merge.
In order to realize that carrying of the present invention merges, need UE support to receive simultaneously in the PTP carrying with the PTM carrying on the MBMS service signal.
Receive each sub-district of same MBMS business for UE, a branch is represented in each sub-district, and the branch that has adopts the PTP carrying, and the branch that has adopts the PTM carrying, by unified adding and the deletion of determining each branch of UE.When there is not other business in UE, and each branch is when all adopting the PTM carrying, and UE is in the RRC idle pulley; When existing branch to adopt the PTP carrying, UE is in the CELL_DCH state of RRC connection mode, at this moment UE need pass through branch's tabulation of MBMS ACTIVE SET UPDATE REQUEST (request of MBMS activating set updating) the message informing network side current UE Active Set of expansion, network side comprises the branch in the tabulation of current UE expectation branch according to the Active Set of branch's list update UE in the Active Set in the Active Set.For PTP branch, UE receives the MBMS business in the PTP carrying of PTP branch correspondence, and for PTM branch, UE receives the MBMS business by PTM RB.
In order not influence the UE that the is in the CELL_DCH state soft pooling function of dedicated channel (only the PTP of PTP branch correspondence carrying sends the MBMS business) when the receiving downlink, when the TFCS of configurating downlink channel (transport format combination set), the transmission block number of getting rid of the transmission block number of signaling transmission channel and service transmission channel is not 0 combination, so that to the soft merging of PTP carrying carrying out of each PTP branch correspondence.UE merges the signal in the PTP carrying of PTP branch correspondence after detecting the TFCI (transformat combination indication) of carrying MBMS business.
When having PTP branch and current best cell (persistent district) or merge cell list in the branch when changing, UE need be with current best cell (persistent district) of MBMS ACTIVE SET UPDATE REQUEST message informing network side and the cell list in the merging branch.Then, RNC is by message MBMS NEIGHBOR CELL LIST (MBMS abutting subdistrict list) the notice UE of expansion, and in this message, the sub-district for the PTM carrying gives the PTM configuration information, is convenient to UE and adds these branches fast.When UE was changed to the CELL_DCH state by idle condition, the cell list that RNC notice UE need monitor was so that the branch that selection can add in these sub-districts.
In addition, when all merging branches all adopt the PTP carrying in the Active Set, to not constraint of each sub-district in the active set (same) with soft handover, promptly, these sub-districts can belong to different RNCs (when having the Iur interface), can belong to different cell set, also can belong to same cell set, the MBMS business derives from SRNC.When all branches in the Active Set all adopted the PTM carrying, these branches must belong to same cell set.Adopt the PTP carrying as part branch, when part branch adopts the PTM carrying, the branch of these PTM carryings must belong to same cell set, the SRNC of this UE is that the affiliated RNC of this cell set is not (if be inconsistent, need carry out the migration of SRNC), these PTP carryings are shared PDCP and RLC entity with this cell set.
In the Active Set of UE all to merge branches all be the PTM carrying, and UE is not when having other business except the MBMS business, UE is in idle condition.When the judgement of UE process branch, discovery need be added the sub-district of adopting the PTP carrying when merging in the branch to, and UE need carry out the transition to the CELL_DCH state of RRC connection mode from idle condition.As shown in Figure 1, UE carries out the transition to the CELL_DCH state of RRC connection mode from idle condition process is described below.
Step 1, UE send RRC connection request (RRC-CONNECT-REQUEST) message at current persistent district to RNC, and the cause value that RRC sets up is that the PTP carrying is set up.
Step 2, RNC and Node B are mutual, set up Radio Link, so that transfer control frame.
Step 3-3 ', RNC send RRC to UE and connect foundation (RRC-CONNECT-SETUP) message, and UE returns RRC connection foundation to RNC and finishes (RRC-CONNECT-SETUP-COMPLETE) message, connects so that set up RRC.
Step 4, UE and RNC and SGSN are mutual, so that UE informs the MBMS business that this UE of RNC need receive in MBMS service request flow process.
Step 5, RNC and Node B are mutual, so that in the reconfiguring radio link process Radio Link is reshuffled, adapt to the transmission of MBMS business.
Step 6-6 ', RNC send radio bearer to UE and set up (RADIO-BEARER-SETUP-COMPLETE) message, UE returns radio bearer foundation to RNC and finishes (RADIO-BEARER-SETUP-COMPLETE) message, so that set up the RB (radio bearer) of carrying MBMS business.
Step 7, UE send MBMS activating set updating request (MBMS-ACTIVE-SET-UPDATE-REQUEST) message to RNC, so that each branch of the current reception of this UE of notice RNC MBMS business.
Step 8, RNC find to also have part to merge branch not in active set, and carrying out Radio Link alternately with Node B increases process, to increase Radio Link.
Step 9-9 ', RNC send activating set updating (ACTIVE-SET-UPDATE-COMPLETE) message to UE, UE returns activating set updating and finishes (ACTIVE-SET-UPDATE-COMPLETE) message, upgrade the active set among the UE, merge branch so that increase in the active set.
Step 10, RNC send MBMS abutting subdistrict list (MBMS-NEIGHBOR-CELL-LIST) message to UE, comprise the sub-district (may be added in the future and merge in the branch) that the current needs of UE monitor in the message, so that UE monitors the sub-district that this message comprises.
When UE was in connection status, owing to the reasons such as mobility of UE, it merged branch or/and each branch's bearing mode can change, and described the handling process when merging branch or branch's bearing mode change below respectively.
Handling process when 1, branch changes
UE is in connection status, when best cell changes, or when merging branch and need change, sends MBMS-ACTIVE-SET-UPDATE-REQUEST message to RNC.
If best cell changes, RNC sends MBMS-NEIGHBOR-CELL-LIST message to UE, upgrades the cell list that UE need monitor.
If upgrade the back all to merge branches all be the PTM carrying, and there is not non-MBMS business in this UE, RNC discharges the RRC connection of this UE.
Increase branch if desired in merging branch, RNC and Node B are mutual to be increased and the corresponding Radio Link of branch that increases, and carries out activating set updating alternately with UE, so that the branch that increases is increased in the Active Set; Delete branch if desired in merging branch, mutual deletion of RNC and Node B and the corresponding Radio Link of deleting of branch are carried out activating set updating alternately with UE, so that the branch of deletion is deleted from Active Set.
Handling process when 2, carrying is changed
When the bearing mode of certain monitored cells changed, RNC sent MBMS-NEIGHBOR-CELL-LIST message to UE, upgraded monitored cells information.The bearing mode of sub-district changes two kinds of situations: be altered to the PTP carrying and be altered to the PTM carrying by the PTP carrying by the PTM carrying, below these two kinds are described respectively.
Be altered to the situation of PTP carrying by the PTM carrying for certain sub-district in the merging branch of UE, according to the present invention, UE need monitor the MCCH channel that adopts PTM carrying sub-district, so that obtain the variation of this sub-district bearing mode when this sub-district is altered to the PTP carrying by the PTM carrying, in time carry out corresponding merging.Particularly, RNC is through Recounting (counting) process, determine that this sub-district is altered to the PTP carrying by the PTM carrying, at this moment, this little PTP bearing mode that has been altered to of indication on MCCH, in the PTP of this sub-district carrying, begin to send the MBMS business simultaneously, in the PTM carrying, stop to send the MBMS business.UE learns that from the MCCH channel this sub-district has been altered to the PTP carrying, so receive the MBMS business information to the PTP carrying of this sub-district.
Be altered to the situation of PTM carrying by the PTP carrying for certain sub-district in the merging branch of UE, RNC is through the Recounting process, determine that this sub-district is altered to the PTM carrying by the PTP carrying, RNC sends MBMS MODIFIED SERVICES INFORMATION message in dedicated channel to UE, in the PTM of this sub-district carrying, begin to send the MBMS business simultaneously, in the PTP carrying, stop to send the MBMS business.UE at first reads MCCH information after receiving MBMS MODIFIEDSERVICES INFORMATION message, then obtains the MBMS business from the PTM carrying.
The invention also discloses a kind of system that realizes carrying merging, comprise: user terminal, be used for each point-to-point branch of active set is carried out soft merging, each is put multiple-limb carry out soft merging or select merging, point-to-point that receives and the Unacknowledged Mode wireless link control protocol data cell of putting multiple spot are selected to merge; Described user terminal also is used for sending the activating set updating request message to radio network controller, receives the abutting subdistrict list message that radio network controller sends; Radio network controller is used for according to mutual foundation of activating set updating request message and base station and/or deletion Radio Link from user terminal, and sends abutting subdistrict list message to user terminal; The base station is used for setting up Radio Link under the control of radio network controller.
According to the present invention, when in there is the cell set of PTP bearing mode sub-district and PTM bearing mode sub-district at the same time in UE, switching, can support the merging of PTP carrying and PTM carrying, waste thereby reduced the power resource that neighbor cell is respectively under PTP carrying and the PTM carrying situation, and improved signal quality when UE is in cell edge.
Though described the present invention by embodiment, those of ordinary skills know, under the situation that does not break away from god of the present invention and essence, just can make the present invention that many distortion and variation are arranged, and scope of the present invention is limited to the appended claims.
