Abstract
The invention discloses a method for reselecting a mobile terminal cell. In the method, user equipment (UE) monitors all cells; when a better cell is detected for the first time, a reselecting timing device is started, and the timing length of the reselecting timing device is set to reselect monitoring time Treselection; a better cell is reselected as a target cell of the reselecting timing device, when the reselecting timing device is closed and the better cell exists, or the reselecting timing device is in an overtime state, the UE judges that if the current best cell meets reselecting conditions, namely, the S of the cell is larger than zero and the R/H value of the cell is the R/H value of a service cell, and the lasting time is larger than or equal to Treselection; and if the best cell meets the reselecting conditions, the UE initiates the reselection of the cell until the best cell is reselected and lingered, otherwise, the UE reselects one better cell as the target cell of the reselecting timing device, the reselecting timing device is restarted so as to continue to monitor all the cells. By the technical scheme in the invention, the best cell can be reselected once when the UE performs cell reselection, thereby reducing reselection time and reducing reselection delay.
Description
Technical field
The present invention relates to the mobile communication terminal technology, specially referred to a kind of portable terminal residence reselecting.
Background technology
In 3-G (Generation Three mobile communication system), the sub-district gravity treatment is (to be called for short, UE) process being closely related of mobility with portable terminal.On the one hand, good sub-district gravity treatment can guarantee farthest that UE resides in the steady quality better cell under the idle pulley, thereby improves the up access success rate of UE; On the other hand, good sub-district gravity treatment can sharp perception external environment change under the idle pulley, in certain reselection delay, guarantee UE from current Serving cell gravity treatment to better sub-district.
Particularly, the signal code power that UE always receives based on the sub-district Primary Common Control Physical Channel that periodic measurement obtained (is called for short, RSCP) measured value, come the S of calculation services sub-district and adjacent cell (to be used for representing the parameter of cell quality, S＞0th, one of necessary condition that the sub-district is resident), R/H (is used for representing the parameter of re-selecting cell priority, it is high more to be worth big more priority, sub-district for hierarchy, operation parameter H, sub-district for the non-layered structure, operation parameter R) relevant parameter such as judges whether to exist S＞0 and the R/H value sub-district (being called for short better sub-district) greater than Serving cell.Description according to 3GPP agreement 25.304, have only and satisfy that keep could be by the UE gravity treatment than the better adjacent cell of Serving cell always in the regular hour section, described time period length---gravity treatment monitoring period (is called for short, Treselection) is broadcasted by system message by network.
The scheme of prior art sub-district gravity treatment is:
1, UE measures the RSCP of Serving cell and each adjacent sub-district, and the S and the R/H value of calculation services sub-district and all adjacent cell;
2, UE detects S＞0 and the R/H value better sub-district greater than Serving cell R/H value;
3, the UE activation pin is to the gravity treatment timer of better sub-district, and setting its timing length is Treselection, monitors better sub-district, if detect a plurality of better sub-districts simultaneously, the general best cell wherein of selecting is monitored;
4, UE continues the RSCP of periodic measurement Serving cell and each adjacent sub-district, does not satisfy S＞0 and R/H value greater than Serving cell R/H value if find this better sub-district in one-shot measurement arbitrarily, and UE closes and monitors the gravity treatment timer; Judge whether to exist S＞0 and R/H value other better sub-districts greater than Serving cell R/H value, if exist, UE is restarted the gravity treatment timer, monitors new better sub-district;
5, gravity treatment timer expiry, UE starts the sub-district gravity treatment, and gravity treatment is resident to the better sub-district of being monitored.
The trigger condition of sub-district gravity treatment is the gravity treatment timer expiry of the better sub-district that occurs at first in the such scheme, and there is following problem in such processing mode:
(1) UE detect one than Serving cell matter measured sub-district and monitor after, if detect other sub-districts in the subsequent cycle measurement than Serving cell better quality, can't influence the sub-district of UE gravity treatment to current monitoring, like this, when best cell is not detected at first better sub-district, UE can not a gravity treatment to best cell, but first gravity treatment is to the better sub-district that occurs at first.
(2) this processing mode can cause system frequent carry out the sub-district gravity treatment because when the UE gravity treatment behind the sub-district that meets reselection conditions that occurs at first, can detect the existence of the better sub-district of follow-up appearance, gravity treatment takes place once more thereby trigger.
(3) because the sub-district of UE gravity treatment is not best sub-district, therefore, the better sub-district, sub-district of the ratio gravity treatment of follow-up appearance can be initiated business professional or that initiated to UE and be caused interference on this sub-district, influence the UE service feature.
Below, reside in Serving cell A by a UE, at first occur one than the better adjacent cell B of Serving cell, and the example than the gravity treatment flow process of Serving cell A and the better sub-district C of adjacent cell B of a follow-up appearance describes.
Because have one than the better adjacent cell B of Serving cell; Come monitor cell B so opened a gravity treatment timer; But before the timer expiry of monitor cell B, because moving of UE end, the variation of the geographical environment in outfield has in addition occurred one than Serving cell A and the better sub-district C of adjacent cell B (when C was best cell, B sub-district itself was still good than Serving cell); So the gravity treatment timer continues monitor cell B.Timer expiry is initiated the gravity treatment to B, and because the stable existence of best cell C, so the very fast gravity treatment of initiating again C.As seen,, but still passed through twice reuse adoption process before initiating the gravity treatment of sub-district B though sub-district C just existed, just final resident to this best cell C.This mode has caused the increase of reselection delay, and has also influenced professional normally carrying out in this process.
Summary of the invention
In view of this, the present invention proposes a kind of portable terminal method of cell reselection,, make UE can a gravity treatment resident to the best cell, reduce the gravity treatment number of times to solve the above-mentioned problems in the prior art.

4, UE proceeds periodic measurement, and revises the gravity treatment mark of each sub-district according to measurement result;
Because B and C signal quality keep better than A always, therefore, after each the measurement, the gravity treatment mark of B and C adds 1 respectively;
5, gravity treatment timer expiry, it is best cell that UE judges C according to the last measurement result;
6, because the monitoring period of C is less than B, and the monitoring period of B is Treselection during timer expiry, therefore, the monitoring period of C: (the gravity treatment mark-1 of C) * measuring period＜Treselection, discontented lumping weight selects condition, and UE is restarted the gravity treatment timer, and setting its timing length is Treselection-(the gravity treatment mark-1 of C) * measuring period, setting gravity treatment timer Target cell is C, continues monitoring B and C;
7, Treselection is overtime once more, and it is best cell that UE judges C, and attaching most importance to of C selects the timer Target cell this moment, satisfies reselection conditions; UE selects C, initiates the sub-district gravity treatment, and gravity treatment is gone up resident to C.
In the application scenarios in the present embodiment, UE has just chosen best cell C through a gravity treatment and has gone up residently, and is Treselection to the monitoring period of C, has reduced the reselection delay of UE gravity treatment to the C.
Specific embodiment 2
The application scenarios of present embodiment is that UE resides in Serving cell A, in periodic measurement, detect than the better adjacent cell B of Serving cell, occurred the interfered cell C (sub-district C declined) that a measurement result fluctuated widely in the short time afterwards again before the gravity treatment timer expiry of monitoring B:
Present embodiment step 1～3 are identical with specific embodiment 1;
4, UE proceeds periodic measurement, and revises the gravity treatment mark of each sub-district according to measurement result;
Because B and C signal quality keep better than A always, therefore, after each the measurement, the gravity treatment mark of B and C adds 1 respectively;
When measuring for the n time, the signal quality that UE detects C is worse than A, and the gravity treatment mark of UE C is set to 0, and after this, because the quality of C is worse than A always, therefore in monitor procedure after this, the gravity treatment mark of C is set to 0 always;
5, gravity treatment timer expiry, it is best cell that UE judges B according to the last measurement result, and B attached most importance to and selected the timer Target cell this moment, satisfied reselection conditions, and UE selects B, initiates the sub-district gravity treatment, and gravity treatment is resident to the B.
In the application scenarios of present embodiment, the maintenance that sub-district B is stable always is better than Serving cell, and the of short duration interference of interfered cell C can not have any impact to the gravity treatment of sub-district B, and therefore reselection delay also can't prolong.
Specific embodiment 3
The application scenarios of present embodiment is that UE resides in Serving cell A, in periodic measurement, detect than the better adjacent cell B of Serving cell, occurred the interfered cell C (sub-district C is decline after the gravity treatment timer expiry of monitoring B) that a measurement result fluctuated widely in the short time afterwards again:
Present embodiment step 1～6 are identical with specific embodiment 1;
7, in the n second periodicity was measured, the quality that UE detects C was worse than A, and the gravity treatment mark of UE C is set to 0, closes the gravity treatment timer;
8, to judge B be current best cell to UE, and (the gravity treatment mark-1 of B) * measuring period＞Treselection, satisfies reselection conditions, and UE selects sub-district B, initiates the sub-district gravity treatment, and gravity treatment is gone up resident to B.
In the present embodiment, UE has arrived on the best cell B by a same gravity treatment of gravity treatment, has avoided the generation of repeatedly gravity treatment situation.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
