Description
Technical field
The present invention relates to satellite mobile communication system, relate in particular to the user information matching method of a kind of satellite mobile communication system under single-hop mode, belong to technical field of satellite communication.
Background technology
The terrestrial cellular mobile communication system has experienced 2G, 2.5G and 3G developing over nearly more than 20 years rapidly, currently strides forward fast to 4G.Wherein, the typical standard that belongs to 2G comprises GSM and IS-95CDMA etc., and the typical standard of 2.5G is GPRS and EDGE etc., and the typical technology standard of 3G is respectively WCDMA, CDMA2000 and TD-SCDMA.
Satellite communication system has many distinctive advantages, such as: can cover scarcely populated area, not need to increase expensive expense; Can provide service for the user on marine and the aircraft; Can share the communication flows of the peak time of ground network; Also can under the state of ground network paralysis, continue as the user service or the like is provided.Also develop rapidly just because of these advantage mobile satellite communication systems.Since the formal provider of nineteen eighty-two Inmarsat uses, many systems have been proposed in succession.The Teledesic system that companies such as the Globalstar system of companies such as the wherein more famous Iridium system that motorola inc is arranged, Qualcomm, the Odyssey system of TRW Ltd. (US) One Space Park, Redondo Beach CA 90278 U.S.A., Teledesic propose, and Inmarsat unites the ICO system of proposition with other companies.
The construction of satellite mobile communication system is also made great efforts towards developing with each direction for Web-compatible of ground.Early stage satellite mobile communication system is built according to 2G (GSM or IS-95CDMA) standard or compatibility mode basically.And in the last few years, the construction of satellite mobile communication system considers generally that then compatible 3G standard designs and plans the BGAN system of the example of this respect such as Inmarsat-4, MSV/Terrestar system etc.Development 3G above satellite mobile communication system is in China and even whole strong current demand arranged all in the world.
Satellite communication system is divided into synchronous satellite communications system and nonsynchronous satellite communication system.Synchronous satellite communications system is a GEO stationary orbit communication system.Nonsynchronous satellite system comprises: medium earth orbit satellite communication system (MEO), HEOS communication system (HEO) and ground orbiter communication system (LEO).Following satellite communication system will adopt GEO ground orbiter communication system; adopt more on high band, multi-beam antenna, the star handle, advanced technologies such as network control in the exchange on the star, star, inter satellite link; can realize with other networks of ground in the interconnecting of Any user; also to satisfy multimedia service demands such as from low speed to high speed speech, data, video, Internet transfer of data; realize anti-interference and can tackle complex electromagnetic environments, shielded service is provided.
In the satellite communication system, the connection between the terminal can be undertaken by the mixing of single-hop mode, double jump pattern and two kinds of patterns.Single-hop mode is meant, the message between end-to-end transmits only to transmit through a satellite just can be finished; The double jump pattern is meant, the transmission of messages between the terminal will be transmitted through twice satellite: once be from initiating terminal via satellite to ground station, once be via satellite to destination in addition from ground station; Hybrid mode is meant, has used above two kinds of patterns in the communication process.Under the double jump pattern, propagation delay is 540ms end to end, and is bigger to the influence of speech quality; And under the single-hop mode, propagation delay is 270ms, and is less relatively to the influence of speech quality, but load is limited in one's ability on the star.Therefore, adopt the signaling double jump, the mixed mode of voice single-hop designs satellite communication network.But also there is certain shortcoming in this system: when the signaling double jump was transformed into the voice single-hop, satellite can't obtain calling party and callee's user profile, and user profile is stored in ground mobile network's the core net.Switching matrix on the uncontrollable star of satellite, with caller and called coupling together, the voice single-hop can't be carried out.For this difficult problem, there has been corresponding research work to carry out and obtained certain achievement:
[Javor P.Kolev, Carsten Hoirup, US Patent 5956646, " Method for synchronizingtransaction identifiers in a mobile satellite communication system " Sep 21,1999] disclose between following two travelling carriages of a kind of single-hop mode the method that connects under using synchronous service to identify to judge, promptly utilized service identification to come identification message whether to belong to same connection.
[John E.Stoner, Kenneth J.Wollack, US Patent 5416770, " Method and apparatus forestablishing dispatch audio communication in a communication system " May 16,1995] method of setting up voice communication between the communication unit in a kind of communication system disclosed.This method utilization identifies to discern whether belong to voice communication together.
But these two kinds of methods all will be made amendment to original protocol architecture, increase identification marking, have increased the handling process of network element, make communication process complicated.
[Chandra Joshi, Anthony Noerpel, Chi-Jiun Su, Dave Roos, US Patent 6314290, " Mobilesatellite system and method for implementing a single-hop terminal-to-terminal call " Nov 6,2001] disclose and set up the satellite communication system of calling out under a kind of single-hop mode between the terminal.In this scheme, single-hop is called out connection foundation back voice and signaling can continue to carry out simultaneously.The control method more complicated of this scheme, complex disposal process.
Generally speaking, the difference of processing mode directly causes the difference of communication network architecture on the star, and some achievements in research have been arranged in this respect:
[Bosch, et al., US Patent 5,839,053, " System for transmitting radio signals from mobileterminals to provide space diversity for uplink signals via geostationary communicationsatellites, " Nov.17,1998] a kind of satellite communication system of utilizing a plurality of GEO orbiters to realize the terminal signaling space diversitys is disclosed.
[MONTE PAUL A, et al., FR Paternt 2901933, " Satellite communication system forcommunicating e.g.data packet; has gateway connected to public switched telephone network; and satellite providing multiple beams; where satellite is in geosynchronous satelliteconstellation; " Dec.7,2007] a kind of multi-beam antenna is disclosed, transparent forwarding on the star, the ground gateway station is finished the satellite mobile communication system of exchange and is formed architectural schemes.
[Joshi, et al., US Patent 6,278,876, " System and method for implementing terminal toterminal connections via a geosynchronous earth orbit satellite, " Aug.21,2001] a kind of system and method for realizing directly connecting between the terminal communication by the stationary orbit multi-beam satellite is disclosed.This is that U.S. Hughes Electronics early start considers that single-hop is carried out direct communication to reduce the design of voice service time delay via satellite, also is the successful technology that was applied to the Thuraya system afterwards.But because this scheme is based on the TDMA/FDMA communication system, handle the mode that adopts the frequency subband exchange on the star, realization that exchange is handled on the therefore corresponding star and controlling schemes are also just simple relatively.
Generally speaking, for the satellite communication system of speech single-hop communication mode, how on existing ground network basis, increasing suitable network element, can be the main contents of this patent so that signaling and voice normally carry out in the Speech Communication just.In addition, increased new network element after, what kind of should carry out to existing communications network functionality and revise and could guarantee to other network element influence minimums, also in the scope of this patent consideration.

Rrc layer provides the mechanism at the transparent transmission Non-Access Stratum of Uu interface signaling message (as MM, CC etc.), and promptly the signaling message of Non-Access Stratum is encapsulated in RRC message as NAS PDU: transmit pellucidly among INITIAL DIRECT TRANSFER, UPLINKDIRECT TRANSFER or the DOWNLINK DIRECT TRANSFER.RRC provides signaling to connect to support the mutual of upper layer information stream to the upper strata.The signaling connection is the affirmation mode link between UE and core net, is used for transmitting upper layer information.
For the ease of the coupling of user profile, consider radio network controller (RNC or GNC) and its two side interface are improved.At first, the wireless access mesh portions increases upper-layer protocol, resolve the information about call proceeding management and connection management that is encapsulated in the RRC message.Secondly, wireless access network still will keep all upper-layer protocols to want transparent transmission to core net, and the purpose of doing like this is to guarantee that the influence of changing for core net is minimum, shown in Fig. 3 and 5.
Under above network configuration, the matching scheme process of caller/called party information is as follows in the call proceeding process:
1) setting up RRC connects.
2) UE connects to RNC transmission initialization direct-sending message by RRC, comprises the initialization NAS information content that UE sends to CN in the message.
3) radio network controller (RNC or GNC) receives the initialization direct-sending message of UE, divides two step process:
One, be that initialization UE message is passed to the CN territory with Non-Access Stratum (NAS) message transformation wherein;
Two, resolve Non-Access Stratum (NAS) information in this message, this message comprises: caller/CSI called subscriber identification, caller wave beam sign, caller CN domain identifier, caller LAI;
In this step, the signaling that the initialization direct-sending message is used to set up between radio network controller and the core net connects, and carries an initial NAS message simultaneously.In order both to guarantee the integrality of ground network original function, guarantee the correct coupling of caller/called user information on the star again, the content of NAS message can produce two copies in this patent in radio network controller, a directly repacking is converted into initialization UE message and passes to the CN territory, passes to the satellite path control deivce after another part parsing.The message structure of initialization direct-sending message is as follows:
