Description

A kind of residence reselecting and device
Technical field
The present invention relates to the communications field, particularly relate to a kind of residence reselecting and device.
Background technology
Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) is 3-G (Generation Three mobile communication system).UMTS system mainly adopts Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, WCDMA) technology.WCDMA is in the world main 3G (Third Generation) Moblie air interface scheme, and abundanter class of business can be provided.Since the third generation moves partner's plan (3rd Generation Partnership Project, 3GPP), since issuing the end of the year 1999 the WCDMA standard that first set comprises complete series, WCDMA mobile communication system has obtained commercial more and more widely in the whole world.
The formation of UMTS system and principle are carried out to brief description below.UMTS system comprises a core net (being called CN, Core Network) and a plurality of RNS (being called RNS, Radio Network Subsystem) conventionally.Each RNS has a radio network controller (being called RNC, Radio Network Controller) and a plurality of base-station node (being called NodeB).Each NodeB distributing radio resource that each RNC is responsible for controlling to it, offers subscriber equipment (being called UE, User Equipment) by NodeB by these Radio Resources.Radio Resource Shi Yi community is configured for basis, and Yi Ge community is exactly the region that the Radio Resource that provides of a NodeB covers.UE is by setting up the wireless channel of transceiving data with the Radio Resource of community, place, for example RRC links Establishing process.
UE has two kinds of basic operational modes: Idle state and connected state.When having set up RRC link, just entered connected state.Under connected state, for efficiently utilize NodeB Radio Resource, adopt less signaling and reduce UE power consumption, under RRC connection mode, be divided into again cell dedicated channel status (CELL_DCH), cell forward access channel status (CELL_FACH), cell paging channel status (CELL_PCH) and user registration area paging state (URA_PCH).Wherein, CELL_FACH state is a kind of state of service rate when lower, uses public physic channel.If speed is higher, network can be configured to DCH state; If there is no speed, will arrive PCH or free time (Idle) state.
In prior art, in order to strengthen the message transmission rate under CELL_FACH state, reduce business recovery time delay, the minimizing UE state transitions time delay from CELL_FACH state to CELL_DCH state of UE under URA_PCH and CELL_PCH state, 3GPP has introduced descending enhancing CELL_FACH state and up enhancing CELL_FACH state in Release 7 and Release 8.UE supports the reception of HSDPA correlated channels and uses HSUPA correlated channels to carry out the transmission of signaling and data under IDLE, URA_PCH, CELL_PCH, CELL_FACH.
But, when 3GPP standard is introduced descending enhancing CELL_FACH state and up enhancing CELL_FACH state in Release 7 and Release 8, the method of cell reselection is not made to any modification and improvement, cause UE when assessment community, supporting descending enhancing CELL_FACH state and up enhancing CELL_FACH Tai community and the community of not supporting to put on an equal footing.Like this, when the community that support to strengthen CELL_FACH and do not support to strengthen CELL_FACH exists simultaneously, may occur supporting the UE that strengthens CELL_FACH from supporting the cell reselection of enhancing CELL_FACH to the situation of the community of not supporting.Above-mentioned situation, sharply worsens the message transmission rate that causes UE under CELL_FACH state, and causes business recovery time delay sharply to increase.
