Background technology
Along with the development of mobile communications industry, the user is to the raising of network quality demand, and it is important that the service quality of wireless network seems further.An embodiment aspect of network service quality quality is exactly a cutting off rate, and especially in handoff procedure, the cutting off rate that how to reduce the user becomes the problem that mobile system must be considered.
The characteristics of LTE (Long Term Evolution, Long Term Evolution) system are the experience that brings large-data operation and high quality-of-service to the user, and therefore, the cutting off rate and the handover delay that how to be reduced in user in the handoff procedure are very crucial.
In the LTE system, have the switching of X2 interface and S1 interface, the process of switching just is meant that evolved Node B (eNB, Evloution NodeB) switches to process in the sub-district of target eNB control to UE (Ueser Equipment, subscriber equipment) from the source.
When UE carries out the sub-district switching, generally include handoff preparation phase and handover execution stage.In handoff preparation phase, portable terminal real time monitoring wireless channel condition, when finding that wireless channel conditions changes, UE meeting notification source eNB, source eNB sending measuring configuration notification UE measures, after UE measures measurement report issued source eNB, source eNB selects a suitable Target cell according to certain algorithm, target eNB under Target cell sends handoff request message afterwards, requiring target eNB is that UE reserves corresponding resource, if target eNB has idling-resource just to send handover acknowledge message to source eNB, otherwise returns switch failure information.
After switching was ready to complete, source eNB sent switching command to UE, and UE disconnects the wireless connections with source eNB, switches to target eNB, sets up wireless connections with target eNB.
The method of the switching that exists mainly is at present:
The Chinese patent application publication number be CN101272588 patent disclosure a kind of " different system switch or gravity treatment ", in this patent when the signal of Serving cell is weak, network side is carried at the adjacent cell list of Serving cell to measure in the control messages and is handed down to this terminal, this terminal is initiated to measure to each adjacent area in this tabulation, and reporting measurement reports, carry out switch decision by network side, select a better quality of signal sub-district to switch.
The Chinese patent application publication number be CN101400088A patent disclosure a kind of " changing method in a kind of evolvement network and equipment ", source eNB sends handoff request message to a plurality of target eNB in this patent, carry the cell ID of preferable cell in the described message, described source eNB receives the message that the affiliated target eNB of preferable cell is returned, and carries the resource that described preferable cell is distributed to the user in the described message; Described source eNB sends to subscriber equipment with resource, for the subscriber equipment access of radio network, finishes switching.
The Chinese patent application publication number be CN101374325A patent disclosure " a kind of portable terminal is realized the method and system that switch the sub-district ", in this patent in handoff preparation phase, source eNB determines destination node and one group of descendant node that is used for downlink data transmission according to metrical information, and the request target node is that UE distributes identical resource with descendant node, resource allocation success back provides descending service by descendant node, then up link is switched to destination node, instantly walking along the street is by after also switching to destination node, notify other descendant node to be released to the resource that UE distributes, thereby solve the influence of the method switched simultaneously up and down in the general service switchover descending large-data operation.
These methods are not all considered the CellBarred information of Target cell in the select target sub-district, the flag bit of promptly not considering CellBarred information is the influence of the sub-district of barred (forbidding) to handover success rate and handover delay.The CellBarred information of sub-district is indicated in the cell system broadcast, whether be used for controlling the sub-district allows the user to insert, if the flag bit of CellBarred information is barred, this sub-district is not allow Any user to insert in a period of time, therefore, source eNB is when the select target sub-district, if do not consider the CellBarred state of Target cell, and with the sub-district of barred as switching target small area, will reduce success rate for switching greatly and increase handover delay, influence user's speech quality.
When the user is in Zone switched the time, the user reports by measurement, and source eNB selects an optimum subdistrict as the Target cell that switches, and notifies the user to switch then.If but when the select target sub-district, do not consider the CellBarred state of sub-district, and selected the sub-district of a barred, when inserting, UE can find that this sub-district forbids inserting, notification source eNB then, source eNB must select an optimal objective sub-district again again, if still selected a barred sub-district this time, source eNB continues to reselect an optimal objective sub-district, if things go on like this will certainly reduce user's success rate for switching greatly, increase handover delay.
Therefore, in order to improve user's handover success rate, reduce the conversation loss rate, source eNB should avoid the user is switched on the sub-district that state is barred.

Embodiment one: present embodiment is based in the Neighboring Cell List that to be switched candidate target cells that source eNB selects is present in source eNB storage and implements.
Concrete, present embodiment is realized preventing from the user is switched to as shown in Figure 2, to may further comprise the steps the flow process of illegal state sub-district:
Step S201, UE monitor the service quality of sub-district, current place and adjacent cell in real time, when the service quality that monitors current area is lower than the service quality of adjacent cell, reports this incident to the source eNB that UE belonged to, and metrical information is reported together.In the present embodiment, described metrical information comprises the measurement result to a plurality of adjacent areas.
The measurement result that step S202, source eNB report according to UE choose service quality best be that the strongest sub-district of signal is as candidate target cells.
Step S203, source eNB judge the CellBarred information that self whether stores this candidate target cells, if, execution in step S206; Otherwise, execution in step S204.
Wherein, the situation of having stored the CellBarred information of candidate target cells for source eNB when the switching judging occurs in the target eNB that source eNB and candidate target cells belonged to and sets up in the process, requires two eNB that set up X2 that CellBarred information is each other passed to the other side.
Below by a concrete example that has X2 between eNB this acquisition process is described:
(1) eNB1 sends X2 to eNB2 and sets up request message, comprises the CellBarred information of each sub-district among the eNB1 in this message;
(2) eNB2 sends X2 to eNB1 and sets up request response, comprises the CellBarred information of each sub-district among the eNB2 in this message.
Need to prove that when the CellBarred of certain sub-district among the eNB that has X2 changed, place, the sub-district eNB that changes informed another eNB by the X2 updating message, guarantee that the CellBarred information of eNB stored is up-to-date information
Step S204, source eNB notice UE reports the CellBarred information in the candidate target cells broadcast.
After step S205, UE receive the notification message of source eNB, read the broadcast message of candidate target cells, obtain the CellBarred information of this sub-district, and this information is reported source eNB.
Step S206, source eNB judge whether the flag bit of the CellBarred information of candidate target cells is barred, if execution in step S207, otherwise, execution in step S208.
Step S207, source eNB the restriction UE switch to this candidate target cells, and according to the measurement result that UE reports choose the residue sub-district in top-quality sub-district as candidate target cells, return step S203.
Step S208, source eNB send handoff request message to the target eNB that this candidate target cells belonged to, and enter the switching standby condition.
Embodiment two: present embodiment is based in the Neighboring Cell List that to be switched candidate target cells that source eNB selects is not present in source eNB storage and implements.
Step S301, UE monitor the service quality of sub-district, current place and adjacent cell in real time, when the service quality that monitors current area is lower than the service quality of adjacent cell, report this incident to the source eNB that UE belonged to, and metrical information reported together, this metrical information comprises the measurement result to a plurality of adjacent areas.
The measurement result that step S302, source eNB report according to UE is chosen the best sub-district of service quality as candidate target cells.
Step S303, source eNB judge the CellBarred information that self whether stores this candidate target cells, if, execution in step S304; Otherwise, execution in step S305.
In this step, identical among its mode of obtaining CellBarred information and the embodiment one if source eNB stores the CellBarred information of candidate target cells, do not do at this and to give unnecessary details.
Step S304, source eNB judge whether the flag bit of the CellBarred information of stored candidate Target cell is barred, if, execution in step S308; Otherwise, execution in step S309.
Step S305, source eNB start the ANR process, and notice UE reports the ECGI information and the CellBarred information of candidate target cells.
After step S306, UE receive the notification message of source eNB, read the broadcast of candidate target cells, obtain the ECGI information and the CellBarred information of this sub-district, and the information of obtaining is reported source eNB together;
Step S307, source eNB add this candidate target cells in the Neighboring Cell List to, and the flag bit of the CellBarred information that reports according to UE judges whether candidate target cells is barred state sub-district, if, execution in step S308, otherwise, execution in step S309.
Step S308, source eNB the restriction UE switch to this candidate target cells, and according to the measurement result that UE reports choose the residue sub-district in top-quality sub-district as candidate target cells, return step S303.
Step S309, source eNB send handoff request message to the target eNB that this candidate cell belonged to, and enter the switching standby condition.
What present embodiment and embodiment one were different is that this scheme can realize in conjunction with the ANR process, and do not need additionally to increase the mutual of UE and eNB, because UE need read the broadcast message acquisition ECGI of adjacent area when neighboring BS relationship obtains, as long as UE reports together with sub-district CellBarred information when reporting ECGI.
The embodiment of the invention is by knowing the illegal state of the Target cell of changing to be cut in advance, thereby can limit the sub-district that the user is switched to illegal state, improve user's handover success rate, reduced user's handover delay, further improved quality of services for users.
