Abstract

Step 1. Via system message or RRC connection built message, UE obtains DRX period (DP) from net side and stores this period in UE. Step 2. UE judges that this period is renewed or not. If it is not, original value is still used. IF it is, UE goes to step 3. Step 3. According to recent RRC state, UE selects corresponding signaling process and sends to the net side the request of modifying DP. In case CE is URA_PCH or CELL_PCH, CE goes to step 7 while CE is IDLE, goes to step 4. Step 4. If UE attaches on CN of PS domain, then goes to step 5 while UE attaches on CN of CS domain, goes to step 6 while UE attaches simultaneously on CNs of PS and CS domains, then UE goes to step 5 first, then step 6. Step 5. Via attaching request /routing section renewing request process, UE modifies DP. Step 6. Via position section registering /position section renewing process, UE modifies DP. Step 7. Via accessing layer signaling, such as cell renewing or URA renewing process, UE modifies DP.

Description

Mobile subscriber terminal adopts the cycle change method of discontinuous receive mode
Technical field
Call/session method for building up and the process, particularly mobile subscriber terminal that the present invention relates to 3-G (Generation Three mobile communication system) (UMTS) adopt the cycle change method of discontinuous receive mode.
Background technology
In 3-G (Generation Three mobile communication system), the main purpose of paging is to seek the callee.Paging is generally initiated by core net (CN), and in addition, radio network controller (RNC) also may be initiated paging.
For power saving, the user terminal (UE) that is under URA_PCH in free time (IDLE) pattern or the connection mode/CELL_PCH state adopts discontinuous reception (Discontinuous Reception (DRX)) mode paging receiving message, DRX cycle is generally by system message broadcasting or special-purpose air interface signaling (setting up message etc. as the Radio Resource control connection) notice UE, so, UE under the IDLE/URA_PCH/CELL_PCH pattern just wakes up every DRX cycle (as 1.28 seconds) and reads Page Indication Channel and judge whether paged, if it is paged, then initiate professional, otherwise enter sleep state, to reduce electrical source consumption.
According to 3GPP 25.331 agreements, the UE under the IDLE pattern obtains DRX cycle (being called CN domain specific DRX cycle length) by receiving system message, and DRX cycle is determined by network side, value is { 640ms, 1280ms, 2560ms, among the 5120ms} one.Under the connection mode, UE sets up message acquisition DRX cycles (being called UTRAN DRX cycle length) such as (RRC Connectionsetup) message or other message such as radio bearer (RB) foundations/reprovision/releases, transmission channel (TrCH)/physical channel (PhyCH) reprovision, cell update affirmation/URA renewal affirmation by the Radio Resource control connection, this DRX cycle is also determined by network side, value is { 80ms, 160ms, 320ms, 640ms, 1280ms, 2560ms, among the 5120ms} one.This shows that connection mode allows UE paging receiving more continually down, to reduce the paging time delay.
When UE received a more than DRX cycle, UE need select a suitable DRX cycle, had stipulated in the 3GPP agreement 25.304 that UE selects the method for DRX cycle:
(1) UE is in the IDLE pattern, if UE is attached to different CN, UE need preserve the CN domain specific DRX cycle length of each CN correspondence, selects wherein minimum one then;
(2) UE is in connection mode, and UE selects of minimum among UTRAN DRX cycle length and all the CN domain specific DRX cycle length.
From top description as can be known, UE is the DRX cycle that passive use network side issues, if therefore UE requires initiatively to revise DRX cycle for certain purpose, prepare to start PoC (Push to talk Over Cellular) business such as UE, because the continuous delay requirement of this service interfacing is higher, so UE wishes to reduce paging time delay and then the reduction time delay that continues by shortening DRX cycle; Or the battery electric quantity deficiency of UE terminal, UE wishes to reduce purposes such as electrical source consumption by prolonging DRX cycle, need provide a kind of method like this, makes UE can ask the DRX cycle of expecting.Further analyze current 3GPP agreement, we have found to define in the 3GPP agreement 24.008 UE can adhere to the DRX cycle size that request (ATTACH REQUEST) or Routing Area Update request (ROUTING AREAUPDATE REQUEST) message are expected to the CN proposition by Non-Access Stratum (NAS) signaling.But there is following problem in this method:
1, this method is confined to the UE attached to packet switching (PS) territory CN, for the UE attached to circuit switching (CS) territory CN, has no idea to allow the DRX cycle of UE active request expectation at present;
2, the request DRX cycle span that UE sends in this method is { 640ms, 1280ms, 2560ms, 5120ms}, promptly consistent with CN territory DRX cycle (CN domain specificDRX cycle length), if UE need ask shorter or longer DRX cycle for specific purpose, agreement is not supported at present;
3, this method is confined to the DRX cycle negotiation between UE and the CN, consults for the DRX cycle between UE under the connection mode and the UTRAN, and agreement is not supported at present.
