Abstract

The present invention relates to a method for supporting common channel packet data (CCPD) service in a CDMA 2000 random access network without using the service channel. A CCPD apparatus requires CCPD service from a network by transmitting an origin information to a base station (BS) where a SDB_DESIRED_ONLY bit is 1, while a FCH_SUPPORTED bit and a DCCH_SUPPORTED bit are 0. When the apparatus is confirmed successfully, SDBs executes PPP connection and mobile IP registration to exchange the information through the common channel. A first SDB is sent to the CCPD apparatus after comfirming the CCPD service requirement from the apparatus by the BS. If the BS can not supprot the CCPD service requirement, SDB will not be sent and the calling is failed. A CCPD MS apparatus requires CCPD service from a network by transmitting an origin information to a base station (BS) where the SDB_DESIRED_ONLY bit, the FCH_SUPPORTED bit and the DCCH_SUPPORTED bit are 1. If the BS refuses the CCPD service requirement, a common packet data processing is executed.

Description

In the CDMA2000 radio access network, be used to support the equipment and the method for common channel block data service

Technical field

The present invention relates to communication system, relate in particular to code division multiple access (CDMA) communication system.

Background technology

Data service generally is grouped into two classes: towards the business (comprising asynchronous data and grouping-3 facsimile services) and the Packet data service of circuit.For the calling of supporting Packet data service, an interface between a packet data serving node (PDSN) sends as the transmission of data in fixed network with above the wave point data.This PDSN is by a Packet Control Function (PCF) interface to a base station system (BS), PCF can with this a BS place or person place that can not coexist that coexists.

According to the definition in the third generation plying project (Generation Partnership Project) 2; In this combination 3GPP2 access network interface inter-operability specification (being called 3GPP2 A.S0001-A hereinafter) as a reference, three Packet data service states are arranged: dynamically/connection, static and zero/as to stop.(the 3GPP2 standard is identical with the standard of the TIA/EIA/IS-2001-A in June calendar year 2001 in content).When MS station (MS) produces packet data call to current C DMA2000 radio access network (RAN), then distribute a Traffic Channel to set up a PPP(Point-to-Point Protocol) and connect, and carry out mobile Internet communication protocol (IP) accreditation process.In case successfully finish these processes, the Packet data service of MS carries out the transition to dynamically/connection status from zero, and this network and MS are by a Traffic Channel exchange grouped data.After a predetermined inactive cycle, the Packet data service of MS is from dynamically carrying out the transition to inactive state, if but this MS or network have the data that will be sent out, then can become once more dynamically.The district's switching of crossing of the still-mode between PDSN also requires to distribute a Traffic Channel to support the setting that a new PPP connects and registers.

Dynamically/connection status in, have a physical traffic channels between MS and the BS, and MS and BS can send data.In inactive state, there is not physical traffic channels between MS and the BS, but remains on the PPP link between MS and the PDSN.In zero/non-dynamical state, there is not physical traffic channels between MS and the BS, and between MS and PDSN, do not have the PPP link.

A1 to A11 interface defines in the part 1.7.2 of 3G PP2 A.S0001-A.Dynamically/connection status during A1 and A8 keep being connected, and to static or zero/non-dynamical state transition period release.Dynamically/connect and inactive state during the A10 maintenance be connected.As the part of supporting inactive state, the supports of CDMA2000 radio or television broadcasting interface (TIA/EIA-IS-2000) use the data on start (Origination) to be ready for sending (DRS).When MS utilized the packet data service option of appointment to send an origination request, this request comprised this DRS bit.When MS wishes to carry out the transition to when dynamic from static, this designator is set to 1 when initial call is set up, because data that will send and the foundation of asking a Traffic Channel are arranged.Subsequently, this DRS bit is set to 0, indication in static this MS transition a packet zone boundary (referring to the part 2.14.1 of 3GPP2 A.S0001-A), and send origination request so that upgrade network about current location.

Be set to 1 origination request in case receive the DRS bit, BS will begin the call setup procedure shown in the part 2.14.7.1 of 3G PP2A.S0001-A, and it causes the foundation of a Traffic Channel usually, and the carrying of setting up A8 and A10 is connected.Being used for the A8 program that carrying is connected with A10 defines in the part 2.14 and 2.15 of 3GPP2 A.S0001-A respectively.Have the DRS bit and be set to 0 one when starting when BS receives, this BS postpones the foundation of a Traffic Channel, after finishing A8 carrying is connected creation facilities program (CFP) with A10.During process is set up in A8 carrying connection, BS indicates this PCF, by using data ready designator (Data ReadyIndicator) unit in A9-setting-A8 information (defining in as the part 2.14.4.1.1. at 3GPP2A.S0001-A) to receive DRS=0.If PCF has the data that are provided to MS from network, then be set to the data value of being ready for sending and represent this situation by the target component in A9-connection-A8 information (defining among the part 2.14.4.1.2 as 3GPP2 A.S0001-A).BS is established to MS to a Traffic Channel subsequently and finishes a normal call setting up procedure of stipulating among the part 2.14.7.10 as 3GPP2A.S0001-A.If PCF does not have data, then do not show not by A9-is discharged-A8 finishes information (definition in as the 2.14.5.4 part of 3GPP2 A.S0001-A) and sends to this BS and set up this A8 and connect.BS turns back to an appointment (Assignment) failure information to have and is set to the MSC that static desired value is carried out in the packet calling subsequently.In case receive the appointment failure information, this MSC turns back to a clearance order has the BS that is set to not notify mobile desired value.Once receiving this clearance order information, BS finishes information to a removing and sends to this MSC.
