For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
For ease of the understanding to the embodiment of the present invention, be further explained explanation below in conjunction with accompanying drawing as an example of several specific embodiments example, and each embodiment does not consist of the restriction to the embodiment of the present invention.
Embodiment one
The handling process of a kind of method of UE being carried out switch decision that this embodiment provides comprises following treatment step as shown in Figure 1:
The value for the unified TTT of at least one adjacent cell that step 11, the base station under Serving cell will arrange sends to UE.
Base station under Serving cell arranges the value of unified TTT and the report cycle T of measurement report at least one adjacent cell of UE, the value of described TTT is determined according to the size of the adjacent cell of the area minimum in all adjacent cells of described Serving cell, concrete, can consider the size of the adjacent cell of above-mentioned area minimum, and the handover failure rate of the whole network of the size of described Serving cell, setting, the value that the pingpang handoff rate arranges above-mentioned TTT.When described Serving cell self is small-cell, the value of smaller above-mentioned TTT can be set.
In actual applications, the value of above-mentioned TTT can be set to 40ms.
Described report cycle T is used to indicate described UE according to described report cycle T periodicity reporting measurement reports.
Base station under described Serving cell sends to described UE with the value of described TTT and the report cycle T of described measurement report.
The measurement report of the information that comprises adjacent cell that the base station reception UE under step 12, Serving cell reports.
after UE receives the report cycle T of the value of above-mentioned TTT and described measurement report, A3 measurement event according to 3GPP agreement regulation is measured signal strength signal intensity or the signal quality of each adjacent cell, if measuring an adjacent cell, UE always satisfies the entry condition of A3 measurement event within the time period of above-mentioned TTT value, it is its signal strength signal intensity or quality always reach a setting higher than signal strength signal intensity or the signal quality of Serving cell within the time period of above-mentioned TTT value threshold value, UE uses to measure and reports process to send the measurement report of the identification information that comprises above-mentioned adjacent cell to the base station under above-mentioned Serving cell.
If UE is within the time period of above-mentioned TTT value, measure the entry condition that a plurality of adjacent cells always satisfy the A3 measurement event, UE uses to measure and reports process to send the measurement report of the identification information that comprises above-mentioned a plurality of adjacent cells to the base station under above-mentioned Serving cell.
The operation that the base station of UE under the above-mentioned Serving cell sends above-mentioned measurement report is that the report cycle T according to above-mentioned measurement report periodically repeats, be that UE is after having sent for the first time above-mentioned measurement report, start immediately the timing operation of above-mentioned report cycle T, after above-mentioned timing finishes, again send measurement report, then, again start the timing operation of above-mentioned report cycle T, go round and begin again.
In the timing course of above-mentioned report cycle T, if UE detects again the entry condition that new adjacent cell satisfies the A3 measurement event, UE use to measure the measurement report of the identification information that reports process to send to the base station under above-mentioned Serving cell to comprise above-mentioned new adjacent cell.Then, the timing of former above-mentioned report cycle T is returned 0, restart the timing operation of above-mentioned report cycle T, after above-mentioned timing finishes, again send the measurement report of the identification information of the adjacent cell that comprises above-mentioned new adjacent cell and reported in the past.

the size information that base station under described Serving cell obtains described adjacent cell according to identification information and the prior information of described adjacent cell, described prior information comprises OAM (Operation Administration and Maintenance, operation, administer and maintain) the UE historical information that receives of base station when each residential quarter relevant information of system configuration and/or described UE switch to this Serving cell under Serving cell, above-mentioned each residential quarter relevant information comprises the size of each residential quarter, the information such as coverage, above-mentioned UE historical information comprises the nearest resident size information of crossing the residential quarter of UE.
When the base station under described Serving cell determined that according to the size information of described adjacent cell described adjacent cell is small-cell, switch decision to described adjacent cell was carried out immediately for described UE in the base station under described Serving cell.
When the base station under described Serving cell determines that according to the size information of described adjacent cell described adjacent cell is macrocell, the switch decision to this adjacent cell is delayed in base station under described Serving cell, continue to receive the measurement report of described UE periodic report, when the number of times that receives the measurement report that includes described adjacent cell when the base station under described Serving cell had reached the numerical value of N of setting, switch decision to described adjacent cell was carried out for described UE in the base station under described Serving cell.Therefore, although the embodiment of the present invention issues a unified TTT value to UE, the TTT value of carrying out switch decision for macrocell actually is TTT+n
*T, wherein n is the random number in [0, N-1] scope, above-mentioned random number n is because the above-mentioned report cycle T of UE may return 0 at any time.
Can be found out by the technical scheme that the embodiment of the invention described above provides, the embodiment of the present invention has realized all configuring unified less TTT value for macrocell and small-cell, does not need to change existing standard, and technical scheme can be used by existing UE.
The embodiment of the present invention is also by taking different switch decision strategies for macrocell and small-cell, report process to be made as periodically the measurement of UE, when making Target cell be macrocell and small-cell, its actual TTT value that comes into force is not identical, can reduce so on the one hand UE to the mortality that small-cell switches, the probability of the pingpang handoff of whole network is remained on below an acceptable thresholding.
