Description
Technical field
The present invention relates generally to field of wireless communications, more specifically relate in communication system, be used to realize the equipment and the method for reduced slotted mode.
Background technology
The call setup that travelling carriage is dialled in calling may need several seconds or the more time finishes.Although this time span can also be accepted for audio call, it has significant negative influence for the call quality of user's impression for data call.Therefore, in typical exploitation, before data call is released as dormancy (dormant) state during data non-effectively (inactivity) in the maintenance Traffic Channel.This data non-effectively during in the data call maintenance that prolongs can cause the poor efficiency use of RF and channel element resources.The time reduce or eliminate the time of delay when being desirably in, just need fast call set-up time to the terminal use keeps acceptable service.
The most important components that travelling carriage is dialled in the call setup of calling is that paging postpones.When in idle condition, travelling carriage operates under the slotted mode usually, so that preserve battery life.Under slotted mode, travelling carriage only monitors the Forward Common Control Channel of paging in specific distributed time slot.Slot cycle index (SCI) control travelling carriage is checked the frequency of paging.Corresponding 1.28 seconds of minimum current standardized SCI (slot cycle index) value (just 0).Like this, even under the situation of using minimum SCI value, under slotted mode, use the paging of the travelling carriage of short-slot-cycle (slot cycle) can be delayed maximum 1.28 seconds.
As the narration of front, support the notion of slotted mode before the cdma2000 standard mesh.In TIA/EIA IS2000.5 standard, in the 2.6.2.1.1.3 part slotted mode is narrated.Yet because the shortest slot cycle is 1.28 seconds, therefore the slotted mode as current definition has remarkable influence to delay in call establishment.Current slot timing device (slotted timer) feature of also supporting of cdma2000 standard.According to this feature, travelling carriage operates under the non-slotted mode, and promptly after the duration specified by slot timing device (being provided by the base station) discharged its Traffic Channel, travelling carriage monitored Forward Common Control Channel constantly.A major defect of this feature is to monitor constantly that Forward Common Control Channel has remarkable influence to the battery life of travelling carriage.And this feature needs fully by base stations control.Travelling carriage can not ask to add (putin) non-slotted mode.
A kind of solution of proposal is to allow reduction SCI value, and this solution has been used the consideration as standard body.If be accepted, this proposal can reduce to 80 milliseconds with short-slot-cycle.Yet under this solution, the sole mode that travelling carriage changes its SCI is to realize by moving registration.Therefore, in order to use reduction SCI (slot cycleindex) effectively, do not waste simultaneously the battery life of travelling carriage, travelling carriage must work as it and registered during variation between reduction SCI value (promptly when grouping data conversation is resting state) and the higher SCI value (when not having dormant packet data session).This causes being increased in the burden on aerial and the ios interface.
Therefore, just need have a kind of equipment and method that realizes reduced slotted mode, it has minimum influence for aerial and ios interface.
