Embodiment
Contrast accompanying drawing and the present invention is elaborated below in conjunction with embodiment.
The gravity treatment measuring process can be monitored the signal strength signal intensity quality situation of current service cell and adjacent area in real time, for the sub-district gravity treatment provides foundation.Measure the sub-district gravity treatment and comprise better sub-district and two processes of service cell signal variation found of measuring.In general, be in non-DCH attitude (usually, the UE state is divided into DCH, FACH, Cell PCH, Ura PCH and IDLE attitude, non-DCH attitude refers to other states except that DCH.) normal resident UE can at first initiate Serving cell and measure, according to the S value of Serving cell measured value calculation services sub-district (, being Sserv) with the S value defined of Serving cell at this.If the Sserv value less than with the threshold value (deriving from system information broadcast) between frequency, alien frequencies, standard the time, is then initiated nearby region measurement between same frequency, alien frequencies, standard respectively, and according to measurement result calculation plot R value.If in a period of time, the signal R value of certain adjacent area is better than the R value (at this, being Rs with the R value defined of Serving cell) of Serving cell always, then thinks to measure and has found better sub-district, measures and finds the gravity treatment of better sub-district.Serving cell signal variation process is meant that Serving cell Sserv value is less than 0, and (this value is DRX (the Discontinuous Reception with current use to lasting Nserv, noncontinuity receives or interruption reception mechanism, by this mechanism periodically monitoring seek channel so that prolong the useful life of battery) a relevant mapping value of cycle, corresponding with the DRX cycle meaning of current use, DRX cycle is notified terminal by resident back Web broadcast) inferior (Fach attitude certain time), it is resident that think that Serving cell is not suitable for this moment, travel through all S values greater than 0 adjacent area, attempt residently according to S value size order one by one, satisfy resident condition sub-district up to finding.
More than describing is the realization principle of sub-district gravity treatment.In the specific embodiment of the invention, at first be on user terminal, to set up a cell information store list tCellInfoList, storage is received from all same frequencies of system information, alien frequencies, (these information spinners will comprise some parameters that need calculation plot S value and R value for ordering to information of adjacent cells between standard, comprise Qrxlevmin (the minimum received signal level that the sub-district requires), MaxTxPower (sub-district maximum transmission power) etc.), and the real-time user terminal physical layer measurement result received signal code power (RSCP) of sub-district (physical layer measure) and the S value calculated according to measurement result, the R value, information such as H value (are calculated the S value by measurement result, the R value, information such as H value can no longer illustrate at this referring to 3GPP agreement 25.304 herein).
User terminal is also safeguarded a storage simultaneously, and all satisfy reselection conditions (S value and R value according to sub-district in the tabulation of above-mentioned cell information judge whether to satisfy reselection conditions.The terminal gravity treatment comprises two kinds of processes, and a kind of is that the Serving cell signal becomes very poor, can not be resident, at this moment need according to S value (the S value is greater than 0) select can be resident the sub-district; Another kind of situation is that Serving cell can also be resident, but finds the better sub-district of signal (the R value is greater than the sub-district of the R value of user terminal current service cell), is more suitable for resident) chained list of sub-district, the space dynamic assignment of this chained list.Element in the chained list comprises the essential information of re-selecting cell: bMeasType (cell type), bCellId (identifying), S value and R value etc. in tCellInfoList.Because sub-district gravity treatment that measure to find better sub-district process and service cell signal variation process is respectively according to the R value and the S value of sub-district, therefore in these two processes the sub-district in the chained list respectively according to R value and the descending ordering of S value, use global flag position bRankingState to identify the ordering state of current chained list, for example can be set to when bRankingState is 1, the current R value of pressing of expression chained list sorts; BRankingState is 0 o'clock, and the current S value of pressing of expression chained list sorts, and vice versa.
As shown in Figure 1, in the specific embodiment of the present invention, a kind ofly handle the flow process that physical layer Serving cell measurement result reports and mainly comprise the steps:
Step 101: preserve the Serving cell measurement result to tCellInfoList, and calculate the S value according to measurement result.
Step 102: whether judge Serving cell S value Sserv greater than 0, jump to step 103 greater than 0, jump to step 112 less than 0.
Step 103: greater than 0 o'clock, calculation services sub-district R value Rs if use HCS (layered cell structure) also needs the H value Hs of calculation services sub-district, and was saved in result of calculation among the tCellInfoList in the S value.
Step 104: (threshold value by the network side band down according to the threshold value Rule of judgment, with the thresholding that has respectively between frequency, alien frequencies, standard separately,, then start homogeneous-frequency adjacent-domain and measure with the frequency thresholding such as Serving cell S value sub-district) determine whether to start with nearby region measurement between frequency, alien frequencies, standard.
Step 105: judge the current UE state.The Fach attitude jumps to step 106, and Idle or Pch attitude jump to step 107.Wherein, Fach attitude, Idle attitude, Pch attitude are several states of user terminal, and be general, and user terminal is divided into Idle attitude (free time) and connected attitude (connection), under the connected attitude, is divided into Fach attitude, Pch attitude.Wherein, the principal character of Fach attitude is: do not distribute special-purpose physical channel to user terminal 1.; 2. user terminal is monitored a descending FACH channel continuously.The principal character of Pch attitude is 1. to distribute special-purpose physical channel to user terminal;
2. user terminal is at descending PCH channel of certain specific monitoring.
Step 106: the Serving cell signal variation timer that starts because of Serving cell signal variation that may exist under the deletion Fach attitude.
Step 107: whether reselection cell linked is empty judgement, if chained list is not empty, jumps to step 108, and chained list is empty, and process finishes.
Step 108: judge current chain list sorting state, the ordering of R value jumps to step 109, and the ordering of S value jumps to step 111.
Step 109: kill the gravity treatment timer.
Step 110: empty reselection cell linked, process finishes.
Step 111: empty reselection cell linked, process finishes.
Step 112:Sserv value is judged the UE state less than 0 situation, jumps to step 113 under the Fach attitude, and the Idle/Pch attitude jumps to step 115.
Step 113: judge whether to start Serving cell signal variation timer under the Fach attitude, if start, process finishes, and does not start to jump to step 114.
Step 114: start Serving cell signal variation timer under the Fach attitude, timer expiry changes step 117, and is not overtime, and flow process finishes.
Step 115: global data bNNumber increases by 1.
Step 116: the Serving cell that whether arrives triggering Serving cell variation is reported number of times, does not reach then process end, reaches then to change step 117 over to.
Step 117: attempt sub-district in the resident chained list, resident success back deletion chained list, if traveled through chained list, the sub-district of not satisfying resident condition, the deletion chained list is initiated the frequency sweep process simultaneously.Measure the better sub-district of finding and might not satisfy resident condition, also need carry out following condition judgment, for example: the sub-district belongs to current network or equivalent network; The sub-district is not by resistance (by system information broadcast); The sub-district does not belong to forbids roaming district or the like.
As shown in Figure 2, in the specific embodiment of the invention, a kind ofly handle the process that physical layer co-frequency neighbor cell measurement result reports and mainly comprise the steps:
Step 101: preserve all and report the co-frequency cell measurement result, simultaneously the S value of calculation plot, R value etc. to tCellInfoList.
Step 102: search Serving cell Sserv value among the tCellInfoList, if the Sserv value greater than 0, jumps to step 103, the Sserv value jumps to step 114 less than 0.
Step 103: according to the HCS operating position and whether high-speed case (using under the HCS situation, not all sub-district all is used for reselection evaluation, may have the restriction of H value greater than condition such as 0) filter co-frequency cell, the co-frequency cell after the traversal filtration.
Step 104: whether the R value of sub-district is better than Serving cell, if bad, jumps to step 108, good then jump to step 105.
Step 105: the ordering state of judging current reselection cell linked.If the ordering of R value jumps to step 107, if the ordering of S value jumps to step 106.
Step 106: empty chained list, remove ordering state indicator variable bRankingState (in this example, bRankingState comprises three values, the ordering state is changed to 0 when not sorting, the R state that sorts, be changed to 1, the ordering state is changed to 2 during the S ordering, during the deletion chained list, then bRankingState is carried out zero clearing).
Step 107: the chained list appropriate location is inserted according to R value size in the measured sub-district of current demand signal matter, judge whether this sub-district has existed chained list before inserting, insert if exist then to delete afterwards earlier.
Step 108: whether traveled through all homogeneous-frequency adjacent-domains, do not traveled through, changed step 104 over to, traveled through and then entered step 109.
Step 109: judge whether current reselection cell linked is empty, if empty, process finishes, and is not empty, changes step 110 over to.
Step 110: judge whether the reselection cell linked header element is co-frequency cell, is not co-frequency cell, process finishes, and is co-frequency cell, changes step 111 over to.
Step 111: judge the header element sub-district of the whether related current reselection cell linked of the gravity treatment timer of current startup, if process finishes, if not, jump to step 112.
Step 112: deletion gravity treatment timer, the association between the sub-district of cancellation gravity treatment timer and startup gravity treatment timer.
Step 113: restart the gravity treatment timer, set up related between chained list header element sub-district and gravity treatment timer, process finishes.
Step 114: under 0 situation of Serving cell Sserv value sub-district, deletion gravity treatment timer.
Step 115: whether the S value of judging Serving cell is greater than 0, if the S value less than 0, changes step 119 over to; The S value changes step 116 over to greater than 0.
Step 116: the ordering state of judging current reselection cell linked.If the ordering of R value jumps to step 117, if the ordering of S value jumps to step 118.
Step 117: empty chained list, remove ordering state indicator variable bRankingState.
Step 118: with the correct position of sub-district, judge whether this sub-district has existed chained list before inserting, insert if exist then to delete afterwards earlier according to S value size insertion chained list.
Step 119: judge whether to have traveled through all co-frequency cells.Do not traveled through, jumped to step 114, having traveled through then, process finishes.
Basically the same frequency processing procedure with above-mentioned is identical for the processing procedure of physical layer measurement result in adjacent area between alien frequencies, standard, from above description as can be known, in above-mentioned example of the present invention, in measuring the better sub-district of discovery process, be designed to the gravity treatment timer and only be associated with the chained list header element, promptly best with satisfying reselection conditions signal sub-district is associated.When the chained list header element changes, the gravity treatment timer will stop, and restart again with after the new chained list header element cell association.The gravity treatment timer was not stopped before overtime, illustrated that then chained list header element sub-district is the best cell that satisfies reselection conditions in timer time always, was that better sub-district is found in the measurement of protocol compliant regulation.It should be noted that, the big expression of R value signal strength signal intensity is good, signal strength signal intensity does not well show and satisfies other above-mentioned resident conditions, therefore may attempt the inferior good sub-district in the chained list, if and the sub-district in the chained list no longer is better than current service cell in during the timing of gravity treatment timer, will from chained list, delete, so the sub-district in the chained list all is the sub-district that is better than Serving cell in the evaluation time of gravity treatment timer.
As Fig. 3, the sub-district gravity treatment implement device of a kind of example of the present invention, be arranged on the user terminal, comprise that cell information is provided with module, re-selecting cell evaluation module, cell information is provided with module and is used to be provided with a cell information tabulation that includes current service cell and adjacent sub-district; The re-selecting cell evaluation module is used for setting up reselection cell linked according to described cell information tabulation, and trigger type according to the sub-district gravity treatment reselection cell linked is sorted, attempt the re-selecting cell in the described reselection cell linked in regular turn, select suitable re-selecting cell as new Serving cell.
The present invention adopts succinct, reliable mode to realize the measurement sub-district gravity treatment of user terminal by tabulation of maintenance record cell information and reselection cell linked, has suitable practical value.Because the relevant information of sub-district gravity treatment was safeguarded in advance before the gravity treatment of sub-district, and is searched the efficient in the time of can effectively improving the sub-district gravity treatment in regular turn by the list structure ordering.
The present invention is when assessing the above-mentioned reselection cell linked that has ordering, only at the header element sub-district of chained list, be the gravity treatment timer that the signal best cell is provided for assessing, need not timer be set, saved overhead at all sub-districts of satisfying R value condition.In finding the process of better sub-district, related by gravity treatment timer and chained list header element sub-district guarantees gravity treatment at first all the time and arrives the best sub-district of signal; Secondly because the related all the time chained list header element of gravity treatment timer sub-district, and after each association, restart, thereby, also be that the signal best cell has continued certain hour and just carries out the sub-district gravity treatment, thereby guaranteed the stability of sub-district gravity treatment only at the gravity treatment timer expiry.Same, in the variation process of service signal sub-district,, utilize the mode that Serving cell signal variation timer or counting Serving cell signal variation number of times are set can guarantee the stability of sub-district gravity treatment according to the different conditions of user terminal.
