Abstract
This invention relates to a method for realizing position refreshment in a CDMA2000 high rate packet data service (HRPD) including the following steps: a, AT judges if the ANID in the AN overhead message is the same with the ANID stored in AT, if so, step f is carried out, if not, the position refreshment flow is carried out. By this invention, HRPD position refreshment process can be added up completely. The terminal knows the current ANID when receiving overhead message, therefore, the terminal can start the position refreshment process actively when ANID changes.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method that realizes position updating process in a kind of CDMA2000 high speed packet data service (HRPD High Rate Packet Data) network.
Technical background
Code division multiple access (CDMA) is a kind of advanced person's a digital mobile cellular telecommunication technology, it is one of 3 most important 3G Radio Transmission Technologys (RTT) technology of International Telecommunication Association (ITU) acceptance, from nineteen ninety by QualCom company issue standard first since, experienced two important stages of CDMA IS95, CDMA2000 1x.
CDMA2000 HRPD (CDMA2000 High Rate Packet Data also claims CDMA20001xEV-DO, the below unified HRPD that abbreviates as) is the upgrading of CDMA2000 1x technology, and high-speed packet data service is provided, and the descending flank speed of single user reaches 2.4Mbps.
ANID:Access Network Identity, the access network sign, promptly (PZID), a tlv triple has identified a PCF network element (Packet Control Function) to tlv triple uniquely for SID, NID.
In the HRPD network, it is to distribute the signalling interactive process of ANID for access terminal (AT) by Access Network (AN) network that (Location Update Procedure) flow process is upgraded in the position, is used to support mobile management.
Stipulate that in the agreement 3GPP2C.S0024 of HRPD the position is upgraded and can initiatively be initiated also can initiatively be initiated by AT by network side.
More the technical scheme of new technological process is as follows to initiate the position by network side:
When AT roams into new Access Network, at first can upgrade the UATI value to the network application, set up Access Network session (Session), initiatively initiate position updating process by network side subsequently, network is distributed to AT with ANID in this process.
As shown in Figure 1, be the schematic flow sheet of this kind situation, as can be seen from the figure, specifically may further comprise the steps:
1) initiates position updating request by AN to AT, inquire about the positional information of current AT.
2) AT notifies AN the ANID of the original storage of AT in the notification message of position.
3) AT notifies AN the essential information of peripheral adjacent area (as PN value, frequency, power etc.) in routing update message.
4) if the former ANID that reports is consistent with the ANID of present AN, AN still distributes to AT to old ANID with location assignment message; If the ANID of former ANID that reports and present AN is inconsistent, AN distributes to AT to new ANID with location assignment message.
5) last AT finishes message with the position and confirms.
As Fig. 2---shown in 7, be the schematic diagram of the information of several reference formats of using in the above-mentioned flow process:
Fig. 2 is a location request message;
Fig. 3 is the position update notification message;
Fig. 4 is a routing update message;
Fig. 5 is that assignment messages is upgraded in the position;
Fig. 6 is the schematic diagram of a value in Fig. 5 " positional value " territory, and " location type " is to represent that " positional value " was null value at 0 o'clock; " location type " be 1 o'clock " positional value " definition as shown in Figure 6;
Fig. 7 is that message is finished in the position renewal:
The shortcoming of being initiated renewal flow scheme in position by network side is as follows:
Initiate when (1) being each Access Network (i.e. the scope of a BSC correspondence) change owing to Access Network session foundation, and the position renewal is to take place when ANID (i.e. the scope of a PCF correspondence) changes, and the scope of PCF is not less than the scope of BSC, so be not that Access Network session each time all needs to carry out the position when setting up and upgrades.This method has increased the weight of network side and has handled burden;
(2) the existing HRPD network support terminal position updating process of initiatively initiating not that is to say that the position update functions of existing HRPD network is imperfect.
Summary of the invention
The purpose of this invention is to provide a kind of new technical scheme, can reduce location update frequencies, to reduce network burden.
For this reason, the present invention adopts following scheme:
Realize the method for position updating process in a kind of CDMA2000 high speed packet data service network, it is characterized in that initiatively initiating more new technological process of position, specifically may further comprise the steps by accessing terminal:
Whether the access network sign in a, the general messages of judging this Access Network that accesses terminal is consistent with the access network sign of AT storage, if inconsistent, then enters step b, if consistent, then enters step f;
B, the access network sign notice Access Network that accesses terminal and in the notification message of position, stored originally accessing terminal;
C, access terminal in routing update message the essential information of adjacent area notice Access Network;
D, Access Network are distributed to new access network sign with location assignment message and are accessed terminal;
E, access terminal and finish message with the position and confirm;
F, flow process finish.
Among the described step a, described message is general messages, comprising: configuration messages (QuickConfig) or Sector Parameter Message (Sector Parameters) and combination thereof fast.
Among the described step a, described message is synchronous (Sync) message or access parameter (AccessParameters) message.
Among the described step c, the essential information of adjacent area comprises: PN value, frequency and power.
In the described steps d, described access network sign comprises system banner, network identity and packet zone sign.
Described method, also being included in accesses terminal is provided with a timer, and sets a duration T, accesses terminal and only finishes T after the time in location registers, just can carry out new location registers flow process.
Adopt the present invention, can obtain following technique effect:
(1) position updating process with HRPD replenishes complete: terminal has just been known when receiving general messages so just might initiatively initiate position updating process by current ANID when ANID changes;
(2) compare with the position updating process that network side is initiatively initiated, frequency is lower, has reduced network side and has handled burden.
(3) the present invention has set up timer, makes when AT moves on the PCF border, can overcome " table tennis " effect that the position is upgraded.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
Do not comprise ANID in each message of the air interface protocol of HRPD, AT just is unable to find out the situation of change of ANID in the process that moves like this, also can't initiatively initiate position updating process.
When AT roams into new AN, at first can upgrade the UATI value to the network application, set up the Access Network session, after adopting the present invention, AT can judge whether the ANID in the general messages (overhead message) of this AN is consistent with the ANID of AT storage, as inconsistent, and trigger position new technological process more then, among the present invention, general messages (overhead message) comprises quick configuration messages (QuickConfig) and Sector Parameter Message (SectorParameters).
More new technological process is as shown in Figure 8 in the position that AT initiatively initiates:
1) AT notifies AN the ANID of the original storage of AT in the notification message of position.
2) AT notifies AN the essential information of adjacent area (as PN value, frequency, power etc.) in routing update message.
3) AN distributes to AT to new ANID with location assignment message.The position assignment information as shown in Figure 5.
4) last AT finishes message with the position and confirms.
Sector Parameter Message in the HRPD network (SectorParameters) is a topmost general messages of describing this sector fundamental characteristics, and information such as sector mark, the geographic longitude and latitude in sector, time are provided.The sector belongs to the base attribute which ANID also is the sector, so suggestion adds ANID in Sector Parameter Message.Particular location is as shown in the table, is added between the CountryCode and SectorID of Sector Parameter Message.
The definition of table 1 Sector Parameter Message
| The territory | Length (bit) | |
| MessageID | ||
| 8 | Message identifier | |
| CountryCode | 12 | |
| SID | ||
| 15 | System banner | |
| NID | 16 | |
| PACKET_ZONE_ID | ||
| 8 | The packet zone sign | |
| SectorID | 128 | Sector mark |
| … | … | … |
Can there be multiple laying method this ANID information position in Sector Parameter Message, also can be placed on other positions, but it is single from saying that in logic to be placed on the position shown in the present figure best, because the scope of CountryCode-＞SID-＞NID-＞Packer_zone_ID is descending.
Terminal has just been known current ANID when receiving general messages like this.This principle is that the position that is similar to CDMA 2000 1x is upgraded.
Need to prove, SetorID adopt be the address format of IPv6, for the CDMA core net, in the process of its structure, used SID, but because AT extracts the intelligence of SID from SetorID, and SetorID do not comprise NID and PACKET_ZONE_ID, so add SID separately in SectorParameters message, NID, PACKET_ZONE_ID are necessary.
In addition, " table tennis " effect that the position is upgraded when moving on the PCF border in order to overcome AT (moves on the border of PCF1 and PCF2 such as AT, might frequently upgrade at PCF1 and the enterprising line position of PCF2 repeatedly), need increase a timer T in AT, duration is default can be made as 1 minute (position in position-based district renewal minimum interval is 1 minute among the CDMA 1x).AT finishes T in location registers just may carry out new location registers after the time.
If when AT moved on the PCF border, AT and AN had initiated the position renewal, AT and AN only need carry out a position renewal and get final product.
Among the present invention, also ANID can be joined other general messages as: among the QuickConfig, perhaps increase new general messages, perhaps join synchronously in (Sync), the access parameter message such as (AccessParameters), also can reach similar effects;
Other positions that ANID joined general messages SectorParameters also can reach similar effects.Such as being added between MessageID and the CountryCode, as shown in the table:
Table 2:ANID is set to general messages SectorParameters
| The territory | Length (bit) | |
| MessageID | ||
| 8 | | |
| SID | ||
| 15 | System banner | |
| NID | 16 | |
| PACKET_ZONE_ID | ||
| 8 | The packet zone sign | |
| CountryCode | 12 | National code |
| SectorID | 128 | Sector mark |
| … | … | … |
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
