Technical field
The present invention relates to wireless communication technology field, particularly paging technique, relates in particular to a kind of method and apparatus of calling called subscriber equipment.
Background technology
In TD-SCDMA system, subscriber equipment (UE) has two kinds of basic operational modes: idle pulley and connection mode.Idle pulley only has (Idle) state of a kind of free time.After UE start, rest under idle pulley, adopt discontinuous reception mode.UE connection mode has four kinds of state: CELL-PCH, URA-PCH, CELL-FACH, CELL-DCH.Wherein, the essential characteristic of CELL_PCH state is: between UE and UTRAN, do not exist DPCH to be connected, and UE also cannot be used any uplink physical channel.Under this state, UE, for saving power consumption, can be used DRX mode to go to monitor the indicated paging channel (PCH) of Page Indication Channel (PICH).When UE completes Radio Resource, control after (RRC) connection foundation, just can from idle pulley, transfer to connection mode, CELL-FACH or CELL-DCH.After RRC Connection Release, UE turns back to idle pulley from connection mode.
When the circuit commutative field of core net (CS)/packet-switched domain (PS) will be used for transmitting data, signaling with certain subscriber equipment (UE) foundation contact, or when UMTS Terrestrial radio access network (UTRAN) side need to trigger the specific event of UE, can send paging acknowledgment to this UE.If called in Idle state or CELL-PCH state, UTRAN can send paging Class1 (PagingType 1) message to this subscriber equipment, otherwise sends paging type 2 (Paging Type 2) message.
Paging Type 1 message sends schematic diagram as shown in Figure 1, and each paging block (Paging Block) consists of a Page Indication Channel piece (PICH Block) and a paging channel piece (PCH Block).The frame number N comprising in Page Indication Channel piece
pICHrepresent the interval N between paging channel piece and Page Indication Channel piece
gAPrepresent the number N of the paging subchannel (Sub-Channel) that paging channel piece comprises
pCHrepresent, every sub-channels takies two frames, so paging channel piece comprises 2 * N
pCHindividual frame.
If the paging indicator that UE is corresponding is 1, this UE must receive paging subchannel corresponding in same paging block, to determine that whether comprising own UE in Paging Type 1 message identifies.If had, paging success, carries out page response.Otherwise UE can ignore PCH piece thereafter, continue DRX and receive.
Each paging subchannel in paging channel piece is mapped on two continuous PCH frames, consistent with the Transmission Time Interval (TTI) of PCH, and PCH transformat (TF) parameter has tri-kinds of TF=0, TF=1 and TF=2.TF=2 represents can send at most in a TTI two PCH transmission blocks (TB).
In 25.331,25.221 and 25.304 current agreements, whether clearly do not stipulate in a paging subchannel only to generate Paging Type 1 message.While adopting TF=2 transformat; two PCH TB generate Paging type 1 message after absolute coding respectively generates Paging Type 1 message or merges coding; agreement does not clearly state; equipment vendors and part manufacturer terminal are understood, realize inconsistent; cause commercial network often to there will be paging failure, affect user awareness.

Embodiment
In prior art, due to equipment vendors and part manufacturer terminal, understand, realize inconsistent, cause commercial network often to there will be the reason analyzing examples of paging failure as follows:
Every Paging Type 1 message all comprises a header, and terminal is carried out message parse according to header.Suppose that network side adopts merging coded system, Paging Type 1 message that all paging acknowledgments in certain paging subchannel are carried out obtaining after ASN.1 coding is divided into two PCH TB, and wherein header is kept in first TB.If end side adopts independent decoding process, first PCH TB is decoded, second PCH TB decoded separately, because second PCH TB do not have header, normally cannot resolve, therefore the paging acknowledgment terminal in second TB cannot be obtained.If the paging acknowledgment of this terminal is just kept in second PCH TB, terminal causes paging failure because not obtaining the paging acknowledgment in this TB.
The handling process of the called device, method network side of paging that the embodiment of the present invention proposes as shown in Figure 2, comprises the steps:
When step 201:RNC processes paging acknowledgment, the paging indicator of called subscriber equipment corresponding to paging acknowledgment is set to 1, at the PO of DRX cycle, constantly by PICH channel, sends paging indication (PI).
Described paging acknowledgment can be that UTRAN oneself produces, also can be that core net issues, paging acknowledgment comprises the international mobile subscriber identity (IMSI of called subscriber equipment, InternationalMobile Subscriber Identity) or temporary mobile subscriber identity (TMSI, Temporary MobileSubscriber Identity).
Step 202:RNC, according to protocol algorithm, is put into described paging acknowledgment in corresponding paging subchannel.If the number of paging acknowledgment does not have to surpass the capacity of first PCH TB in paging subchannel, first PCH TB in this paging subchannel is carried out to ASN.1 coding and generate a Paging Type1 message.If two PCH TB have paging acknowledgment in this paging subchannel, two PCH TB are independently carried out to ASN.1 coding and generate two Paging Type 1 message.
The handling process of the called device, method user of the paging side that the embodiment of the present invention proposes as shown in Figure 3, comprises the steps:
Step 301: adopt all subscriber equipmenies of discontinuous reception all can constantly monitor PICH channel at the corresponding PO of each DRX cycle, if listening to the paging indicator of oneself is 1, performing step 302, is 0 if listen to the paging indicator of oneself, continues execution step 301.
Subscriber equipment all uses discontinuous reception mode under IDLE, CELL_PCH or URA_PCH state.Subscriber equipment only can receive one time beep-page message in each DRX cycle, and the moment of this paging receiving message is called PO constantly.DRX cycle length of Typical Disposition is 1.28 seconds, and the PO of different user devices is constantly also incomplete same.The PO of each DRX cycle constantly subscriber equipment monitor PICH channel, and at other constantly in " standby " state.
Step 302: if having two PCH TB in paging subchannel corresponding to subscriber equipment, two PCH TB are carried out respectively to ASN.1 decoding and obtain two Paging Type 1 message, if only have a PCH TB in paging subchannel, this PCH TB is carried out to ASN.1 decoding and obtain PagingType 1 message.
Step 303: subscriber equipment inspection decoding obtains whether comprising the user ID of self in Paging Type 1 message, if so, perform step 304, otherwise this subscriber equipment is proceeded discontinuous reception, returns to step 301.
Step 304: the Non-Access Stratum of notification of user equipment oneself (NAS) carries out beep-page message response.
Beep-page message will be through just issuing after ASN.1 coding, and for the paging (being the IMSI that comprises called subscriber equipment in paging acknowledgment) of IMSI type, after each paging acknowledgment coding, length is 72bits; For the paging (being the TMSI that comprises called subscriber equipment in paging acknowledgment) of TMSI type, after each paging acknowledgment coding, message-length is 40bits; Every Paging Type 1 message has the header of a 7bit size, and PCH TB size is 240bits.
Suppose to have in certain paging subchannel the paging acknowledgment of 10 TMSI types, adopt the capacity comparison of two kinds of different coding modes as shown in table 1
Table 1
As can be seen from Table 1, adopt merging coded system the paging acknowledgment of 8 TMSI types can only be put in Paging Type 1 message at most, two TB of absolute coding mode can comprise the paging acknowledgment of 10 TMSI types at most, promote 1/4 paging acknowledgment number, improved significantly paging capacity.
The embodiment of the present invention also proposes a kind of device of calling called subscriber equipment, and described device is positioned at radio network controller, comprising:
Paging indicating module, for the paging indicator of called subscriber equipment corresponding to paging acknowledgment is set to 1, constantly sends paging by Page Indication Channel PICH at the PO of DRX cycle and indicates;
Coding module, be used for according to protocol algorithm, described paging acknowledgment is put in corresponding paging subchannel, if two paging channel transmission block PCH TB have paging acknowledgment in this paging subchannel, two PCHTB is independently carried out to ASN.1 coding and generate two paging Class1 message.
Preferably, if the number of paging acknowledgment does not have the capacity over a paging channel transmission block PCH TB in paging subchannel, described coding module generates a paging Class1 message for first PCH TB of this paging subchannel being carried out to ASN.1 coding.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
