Under mobile status, when the user uses MBMS when service, according to present protocol processes, when gravity treatment was to the sub-district of not supporting the MBMS service or not on the sub-district of same MBMS domain addresses, the MBMS business can be interrupted.
A kind of district reselecting scheme is provided, in the prior art in LTE (Long Term Evolution, Long Term Evolution) system; Rule of judgment before the district reselecting is divided according to frequency priority, and wherein the priority of each frequency is at eNB (evolved Node B; Evolved base station) sends in the system message; Frequency priority from 1 to 7 is totally 7 grades, and wherein 7 is that frequency priority is the highest, and 1 is that frequency priority is minimum; Be divided into three types through adjacent area frequency priority and service subdistrict frequency point priority:
(1) the adjacent area gravity treatment Rule of judgment that equates with Serving cell frequency priority; Mainly on alien frequencies adjacent area, use with frequency and isopreference level;
(2) the adjacent area gravity treatment Rule of judgment higher than Serving cell frequency priority; Mainly on the alien frequencies adjacent area of high priority, use;
(3) the adjacent area gravity treatment Rule of judgment lower than Serving cell frequency priority; Mainly on the alien frequencies adjacent area of low priority, use.
For the adjacent sub-district that equates with Serving cell frequency priority, to sort according to the R value, gravity treatment is arrived the most forward sub-district of R value rank as the gravity treatment Target cell.Concrete, Rs=Qmeas, s+QHyst, Rn=Qmeas, n-Qoffset, wherein Rs representes the R value of Serving cell, Rn representes the R value of adjacent sub-district; Qmeas, s represent Serving cell received signal quality measured value, and Qmeas, n represent adjacent sub-district received signal quality measured value; QHyst representes the magnetic hysteresis value; On behalf of the deviant between Serving cell and the adjacent sub-district, Qoffset be specially the desired difference of received signal quality between Serving cell and the adjacent sub-district.
State in realization in the process that guarantees the MBMS business continuance, the inventor finds to have following problem in the prior art at least: when the sub-district that has two isopreference levels, one is the sub-district in same multimedia broadcasting territory, and another is non-multimedia broadcasting sub-district; And the R value of non-multimedia broadcasting sub-district is greater than other sub-districts, at this moment UE will gravity treatment to non-multimedia broadcasting sub-district, this moment, original MBMS service will be interrupted.Under current this reselection constraint, can only guarantee the continuity of persistent district, can not the maximized continuity that guarantees the MBMS service.
