Description

A kind of method that realizes using the wireless terminal roaming of fixed number

Technical field

The present invention relates to wireless communication field, particularly use the method for the roaming of fixed network number and wireless terminal.

Background technology

Current domestic communication network can be divided into mobile network and fixed network, does not have the notion of roaming in fixed network originally.But, use the roaming of fixed number terminal to be restricted because of the standard of existing network along with carrying out of fixed network wireless communication service.

Fig. 1 is to use the network (being called for short fixed network later on) of fixed number and uses the networking connection diagram of the net (being called for short mobile network later on) of mobile number.Wherein the whole network is represented with 10, and fixed network represents that with numeral 20 mobile network is represented with numeral 30.The network entity that fixed network comprises has the LS of end office (EO), and (wherein LS1 is the wireless end office (EO) in roaming place, LS2 is the wireless end office (EO) of ownership place), the caller location OTM of tandem exchange, caller location toll switch OTS, called location toll switch TTS, the roaming wireless local user ownership place TTM of tandem exchange, the fixed network critical point GW of office.The network entity of mobile network has the GMSC of mobile gateway office.Do not list among Fig. 1 with the present invention and do not have closely-related network entity.

Transmit the requirement of standard according to state's Intranet internetwork number: the fixed network user dials local mobile subscriber, and called number adopts 13XH0H1H2H3ABCD form, national number attribute; The fixed network user dials the strange land mobile subscriber, and called number adopts 0+13XH0H1H2H3ABCD form, national number attribute.In present network, if the fixed network user dials local mobile subscriber, called dialing is the 0+13XH0H1H2H3ABCD form, and perhaps the fixed network user dials the strange land mobile subscriber, called dialing is the 13XH0H1H2H3ABCD form, all can be considered as invalid dialling by system and lead to the failure.The rule (for convenience of description, this rule definition is regular A) that this Personal Handyphone System(PHS) user who judges that restriction is roamed dials the number of its ownership place is widely used in mobile gateway office (as the GMSC among Fig. 1) and part tandem exchange (OTM).

In the wireless telecommunication system that uses the fixed network number resource, correct in order to guarantee caller ID display if exist the user to roam, when this roamer called out fixed network or mobile network user, the caller that this user shows was 0+ ownership place area code+Subscriber Number form.At this moment there is a problem: when this roamer calls out the ownership place mobile number, dialing custom according to the fixed network user, should adopt the 0+13XH0H1H2H3ABCD form, at this moment, because calling number is 0+ ownership place area code+Subscriber Number form, the system of application rule A thinks that local fixed-line subscriber dials local mobile subscriber, and called number should not add 0, causes call failure.If this roamer calls out the ownership place mobile number, at this moment called employing 13XH0H1H2H3ABCD form is analyzed called number in the caller location of roaming place tandem exchange, and discovery is nonlocal mobile number, and do not have 0 before the number, also can cause call failure.Present normally used processing mode is the judgement that requirement mobile gateway office and tandem exchange do not carry out regular A.But because mobile gateway office and tandem exchange's number are numerous, relate to the equipment of different manufacturers and different operators, some equipment is longer because of service time, can not evade by software upgrading, the realization difficulty that these have all increased this mode causes very difficult enforcement of this mode or cost too high.

Summary of the invention

The object of the invention is exactly to realize using the roaming function of the wireless terminal (for convenience of description, the back claims to use the wireless terminal of fixed number to be Personal Handyphone System(PHS)) of fixed number by the processing that standard has end office's (it is wireless end office (EO) that the back weighing-appliance has the end office (EO) of wireless communication function) of wireless communication function.

Realize that method of the present invention comprises the steps:

When a1) Man You Personal Handyphone System(PHS) user registered, the wireless end office (EO) in roaming place preserved this user's information of home location and user number information;

When b1) Man You Personal Handyphone System(PHS) user dials nonlocal mobile subscriber, if roaming place tandem exchange uses the Personal Handyphone System(PHS) user of restriction roaming to dial the rule of the number of its ownership place, then called number is transformed to the form of route prefix+mobile number, continues to the roaming place toll switch through described tandem exchange then at roaming place wireless side intra-office;

C1) described toll switch is transformed to the form of 0+ ownership place area code+Mobile terminating call number with called number, and passes through ownership place toll switch and fixed network gateway and mobile network gateway complete connection.

Further, the route prefix above-mentioned steps b1) is a kind of in international long-distance prefix+national code, national code, national distance prefix+area code, national distance prefix, the empty form.

Further, the information of home location of above-mentioned roaming wireless local telephone network is that ownership place area code or other can get access to the information of area code, comprises area code allocation list index.

Further, if not using, roaming place tandem exchange do not limit the rule that casual this user dials the number of its ownership place, then at wireless side intra-office called number transparent transmission.

The present invention only need have the wireless end office (EO) of wireless communication function and corresponding gateway exchange and just handle according to the present invention and can solve this contradiction in existing system.Needs are adjusted problem that whole network solves narrow down to and revise on a spot of equipment, engineering construction more tallies with the actual situation, small investment, and instant effect is safeguarded simple.

Embodiment

Below in conjunction with accompanying drawing enforcement of the present invention is explained.

The wireless terminal that uses fixed number is that the Personal Handyphone System(PHS) user is when roaming, the at first wireless LS1 of end office (EO) registration in the roaming place, the wireless end office (EO) in roaming place obtains user's ownership place area code and Subscriber Number from roaming wireless local user's home subscriber database, and is retained in the user data area of the wireless LS1 of end office (EO) in roaming place.The user ascription area information that the wherein wireless LS1 of end office (EO) preserves is not limited to area code itself, also can be other information that can get access to area code, as area code allocation list index.This information that keeps is used for caller ID display.

The Personal Handyphone System(PHS) user makes a call at the wireless LS1 of end office (EO) of roaming place, and called is nonlocal mobile network user, calls out the toll switch TTS that is transferred to callee's ownership place through the OTM of roaming place tandem exchange tandem to roaming place toll switch OTS.TTS is transferred to the mobile network critical point GMSC of office with the fixed network critical point GW of office with calling.The GMSC of mobile gateway office finishes called handshaking procedure.

Fig. 2 illustrates that wireless end office (EO) works judgment processing process when exhaling the roaming wireless local user.

100 roaming wireless local users make a call.

110 roaming places are wireless, and the LS1 of end office (EO) analyzes called number.

If 120 called subscribers are non-moving network users, execution in step 400.

If 130 called numbers are local mobile network user, execution in step 400.

If 150 called numbers are nonlocal mobile network user, the possibility that regular A is revised, execution in step 200 there is this moment.

200 judge whether to need to adopt regular A.This judges that whether the judgment processing of executing rule A is relevant with OTM, if OTM is executing rule A not, then execution in step 250.If the judgement of OTM executing rule A, then execution in step 300.

250 owing to OTM does not judge regular A, so the wireless end office (EO) in roaming place does not need to revise called number transparent transmission user's dialing " 0+13X H0H1H2H3 ABCD ", execution in step 400.

Step 300 OTM judges regular A, need wireless end office (EO) revise in the roaming place.The wireless end office (EO) in roaming place obtains the special number prefix of configuration, and we are referred to as route prefix, and this route prefix can be: be forms such as international long-distance prefix+national code, national code, national distance prefix+area code, national distance prefix, sky.The called number of revising in the initial address message is " route prefix+13X H0H1H2H3 ABCD " form.Execution in step 400.

In 400 initial address messages, the calling number zone comprises roaming wireless local user's information of home location, can adopt " ownership place area code+Subscriber Number form ".

500 follow-up handshaking procedures are identical with original handshaking procedure, finish call proceeding according to original processing procedure.

Fig. 3 illustrates the signaling transmittance process when the Personal Handyphone System(PHS) user dials nonlocal mobile network user.And the specific embodiment of the invention is described as example.

In conjunction with the accompanying drawings 3, it is as follows that the Personal Handyphone System(PHS) user of roaming dials nonlocal mobile network user signaling transmittance process:

A) Man You Personal Handyphone System(PHS) user dials nonlocal mobile network user, and subscriber dialing is " 0+13XH0H1H2H3 ABCD ".The roaming place is wireless, and the LS1 of end office (EO) identifies the called subscriber is nonlocal mobile network user, and then when the OTM of roaming place tandem exchange sent initial address message, the called number in the message adopted " route prefix+13X H0H1H2H3 ABCD " form.

If the OTM of roaming place tandem exchange does not carry out judgement and the restriction of regular A to numbers of calling and called parties, then route prefix can be a national number prefix 0; If OTM carries out the judgement of regular A to the ownership place of calling and called, then route prefix can international long-distance prefix+national code, national code, national distance prefix+area code, national distance prefix, empty form.Use the advantage of national code to be that the processing mode of LS1 is simple; Use the advantage of national number prefix+ownership place area code to be that subsequent exchange office does not need again called number to be carried out conversion.

B) OTM of roaming place tandem exchange sends initial address message to roaming place toll switch OTS.

If OTM does not carry out judgement and the restriction of regular A to numbers of calling and called parties, the called number that sends of the transparent transmission of OTM LS1 then; C) toll switch OTS in roaming place sends initial address message to dialed field toll switch TTS.At this moment called number is transformed to " 0+ ownership place area code+13X H0H1H2H3 ABCD " form at roaming place toll switch OTS.

D) dialed field toll switch TTS sends initial address message to the fixed network critical point GW of office.Called number is " 0+ ownership place area code+13X H0H1H2H3 ABCD " form.

E) GW of fixed network critical point office will send initial address message to the GMSC of mobile gateway office.Called number is transformed to " 13X H0H1H2H3 ABCD " form at the fixed network critical point GW of office.

F) GMSC of mobile network critical point office finishes called call proceeding, and calling and called are called out normal foundation.

Should be understood that the above-mentioned description at specific embodiment of the present invention is comparatively concrete, can not therefore be interpreted as the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
