Abstract
一种用于向无线终端(例如电话)用户提供区域具体信息的系统和方法。区域具体信息在公共辅助链路上使用可用消息格式进行周期性发送(204)。如果电话处于区域中，它将接收信息(208、210)。如果信息指向该电话(220)，电话将处理该信息(224)并将信息显示给用户(228)。如果信息不是指向该电话(220)，就丢弃该信息(230)。在CDMA无线电话系统中实现的实例是在特定区域的寻呼信道上使用特征通知报文广播来提供区域具体信息。使用广播寻址来提供该信息。使用特征通知报文在寻呼信道上广播区域具体信息导致移动电话所需的接入信道登记消息数的减少。第二实施例使用结合短消息服务(SMS)的广播寻址来提供区域具体信息。广播寻址的优势在于区域具体信息可以发送给无线终端的分组。这就允许在具有目标为不同无线终端的各种区域具体信息的同一区域中广播。
A system and method for providing area specific information to wireless terminal (eg, telephone) users. The area specific information is sent periodically (204) over the common auxiliary link using an available message format. If the phone is in the zone, it will receive the information (208, 210). If the information is directed to the phone (220), the phone will process the information (224) and display the information to the user (228). If the information is not directed to the phone (220), the information is discarded (230). An example of implementation in a CDMA wireless telephone system is the use of feature notification message broadcasts on a region-specific paging channel to provide region-specific information. Broadcast addressing is used to provide this information. Broadcasting zone specific information on the paging channel using feature notification messages results in a reduction in the number of access channel registration messages required by the mobile phone. A second embodiment provides area specific information using broadcast addressing in conjunction with Short Message Service (SMS). The advantage of broadcast addressing is that area specific information can be sent to packets of wireless terminals. This allows broadcasting in the same area with various area specific information targeted to different wireless terminals.
Description
Technical field
The present invention relates to radio communication.Specifically, the present invention relates to a kind of improved system and method that is used to use their current zone of living in of broadcast address feature notice message prompting wireless device.
Background technology
In wireless communication system, honeycomb or personal communicator (PCS) telephone system for example, system is divided into many coverages physically.Coverage can be defined jointly by physics and non-physical constraint condition.Coverage by service supplier's identity definition is a kind of example of non-physical constraint condition, and is to be physical constraint with geographical, transmitter power and receiver sensitivity by the coverage (for example sub-district) of single base station transceiver definition.The service supplier is divided into many less zones with its coverage.Each zone comprises the sub-district by the definition of single base station transceiver at least, and may comprise many sub-districts.The size in each zone is defined when the system design by the service supplier.
Coverage with service supplier's identity definition is extremely important for the record keeping purpose.Assign telephone numbers also also is appointed as the local service offerings merchant of this device for certain wireless devices provides the service supplier of bill.When outside its service supplier's coverage, using wireless device, just be called roaming.The cost of roaming phone is usually above the cost of call in local service offerings quotient system system.Because the expense variance between this locality and roaming call, when phone was in roaming condition, wireless device used the additional information that sends to wireless device from the base station to inform the user.Wireless device provides a designator to inform user's roaming condition usually on phone display.
In service supplier's coverage, also can use same this locality/roaming notion.Service supplier's coverage is divided into zones of different and provides the zone for the service supplier provides according to the progression price plan.In this scheme, when increasing, wireless telephone user will little by little be paid higher calling price when the distance (being measured by number of regions) from predetermined local zone.This zone based on the progression price plan is similar to the employed record keeping convention of PSTN (PSTN) service supplier.Yet with PSTN based on the zone of institute's dialing numbers formulate call out price different be to be that originating call is formulated in what zone according to radio telephone from calling price based on the radio telephone zone.
Wireless telephone user will face and problem that PSTN (PSTN) telephone subscriber can not experience is to be caused by wireless telephonic mobility.Wireless telephonic mobility makes determines that in real time the radio telephone regional location becomes most important.When the radio telephone calling of starting, and, must determine the zone at radio telephone place when calling out when keeping.During the unitary call process, radio telephone can move to another zone from a zone.
A kind of possible solution requires to register to system when radio telephone is crossed over the zone boundary at every turn.Response phone registration message, the base station by message response registration phone tell it its in what zone.Every kind of radio telephone system (no matter being what modulation type) has some regulations to the mobile phone registration.Code division multiple access (CDMA) cellular system interface has explanation in the MOBILE STATION-BASE STATION of the interim standard TIA/EIA/IS-95 of telecommunications industry association (TIA) and Electronic Industries Association (EIA) COMPATIBILITY STANDARD FORDUAL-MODE SPREAD SPECTRUM SYSTEM.
Such as in TIA/EIA/IS-95 definition, cdma cellular telephone has multiple enrollment mode.This standard definition in cdma system supported 9 kinds of different register methods.Different registration forms has that power rises, power descends, based on timer, based on distance, based on the zone, in order, communication channel, parameter change and implicit.
In cdma system, each base station periodically sends additional messages at any phone in its overlay area on the paging channel.Additional messages sends to phone as system parameters message, and comprises system banner (SID) number and network identity (NID) number.From these two numbers, phone can judge whether it is in the coverage of its local system.The phone that is not in the local overlay area just thinks to be in roaming.Because call out usually above the same phone of sending from local system by the expense that roaming phone causes, so phone will show roaming state.
In addition, system parameters message comprises the data field of registration zone.The registration zone related with SID and NID number can start the mobile phone zone according to registration.Phone saves as a zone list, ZONE_LIST with its zone of registering.Be stored in number of regions among the ZONE_LIST and be the variable that to set by the data field in the system parameters message.Phone compares the record among the SID in the system parameters message that is received, NID and registration zone information and the ZONE_LIST.If SID, NID and registration zone information have not been stored among the ZONE_LIST, phone just begins registration on access channel.
Keep nearest ZONE_LIST by the zone list timer that starts every record among the ZONE_LIST.When the timer of any specific record among the ZONE_LIST expired, this record was just removed from tabulation.Equally, if new zone of the information that in system parameters message, is received indication, and in ZONE_LIST, would exist the zone of maximum number, phone will use the zone list timer to determine the oldest record and it is deleted from tabulate.
Based on the zone of registration make aspect the paging channel maximum capacity particularly useful.Beep-page message can point to those phones that only uses these base stations of nearest registration.By eliminating, just make the system resource maximization only for guaranteeing that unique user receives the demand of beep-page message to all base station broadcast beep-page messages.
General areas based on registration can be revised as long as phone enters the zone, just allows to phone sending zone information.In order to realize this target, need be configured system, like this, the record number of keeping in ZONE_LIST is limited in 1.This just guarantees that phone will send registration message as long as phone is crossed over the zone boundary.In response to the phone registration, the base station sends guide message to the registration phone and informs subscriber-related zone state.This guide message can be the text message that is shown to the user.Subsequently, the user knows the current region state with federation, and will probably know charging rate corresponding in this zone.
Yet, have many defectives in Pei Zhi the system by this way.Because the record numeral among the phone ZONE_LIST is reduced to 1, so the number of times that phone must be registered in system will increase.When working in the bounds of phone between two zones, the increase of the registration message number that phone sent is the most tangible.When phone was worked in borderline region, it was repeatedly crossed between the coverage in two zones possibly.Because the record number among the ZONE_LIST is restricted to 1, so phone just must send registration message when receiving the system parameters message of indication zones of different at every turn.Its result has increased the number of times that phone must send registration message greatly.The increase that sends the registration message number of times causes exhausting of electric weight in the phone, thereby has reduced effective standby of phone and air time.Many phones continue to send registration message and can make access channel over-burden and exert an influence.As long as on the main channel, there is the zone boundary, will exist because the problem that effective registration message transships access channel a large amount of phone the time.
In addition, every registration message can trigger the additional guide message of informing zone registration phone.Guide message is sent to each phone according to their definition.By current method for designing of informing telephone subscriber's domain of dependence information, can increase the guide message amount greatly.This just causes the capacitance loss of paging channel.
The equilibrium mutually that is benefited of their current region is not known in the loss of access channel and paging channel capacity with the user.And, if only supported a few users among the user to use, make under the favourable situation of fraction user by the service supplier based on the zone of progression price plan, concerning this system and most of user, all be very unfavorable.Because the increase of the registration message number of times that phone is required makes every telephone subscriber only have less air time and stand-by time, and it is only helpful to the minority among the progression price plan user to replenish the area information that receives.
We are needed to be a kind ofly can point out the user area information in the progression price calling scheme and don't can reduce wireless system performance or infringement is not in the system and method for the user benefit on the same call scheme.
Summary of the invention
The present invention is a kind of improved system and method that uses broadcast address characteristic notice message to point out subscriber-related area information.Perhaps, can use Short Message Service (SMS) message to inform user area information.
The base station periodically sends the prompting of broadcast address characteristic or contains the SMS message of text message, and this message is informed the zone at user base station place.For distributing specific broadcast address based on the phone on the zone of progression price plan.Use other other phones of calling out scheme not distribute identical broadcast address.Phone with broadcast address can judge that address information is to point to this phone.The phone that does not have broadcast address only abandons this information.Thereby the phone on the progression price plan can continue to user's update area domain information.This does not have adverse influence for those phones that do not belong to the progression price plan.Because do not need phone to send registration message for responding area information message, thereby, kept the power system capacity on the access channel.Capacity on the paging channel only has the minimizing of rated quantity, and the minimizing level can not reduce to instruction message the time.Because broadcast allows to point to many users' single transmission, and guide message only allows each the transmission to have only a recipient, so the use of broadcast is more effective than guide message.

Embodiment
In cdma wireless telephone system, exist several can being used for that information is sent to message format on the phone from the base station according to TIA/EIA/IS-95 work.Two kinds of such available message forms are feature notice message and Short Message Service (SMS).
Feature notice message sends to phone from the base station on paging channel.A field in the feature notice message allows this message to utilize broadcast addressing.
Broadcast addressing allows the base station simultaneously with the many phones of single message directs.Many phones can be shared same broadcast address.If telephone configuration is reception broadcast address message, and disposes specific broadcast address, phone will be handled this message.The guide message that this and base station use the phone moving station mark number to send to particular telephone differs widely.
The use of broadcast addressing has advantage, because a piece of news can point to many recipients, and because message can only offer the individual that those these message can provide useful information.Under the regional situation of keeping accounts based on the progression price, for those phones on the price plan distribute specific broadcast address, any phone that is not in this price plan does not comprise this address.Have only those phones on the progression price plan just can handle the regional identification message that uses broadcast addressing to send.This with cross over the method that all will register the zone boundary at every turn and differ widely when phone.The difference configuration can not be carried out in the telephone booth that phone is registered in the same system.If just need all phones registrations as long as cross over the zone boundary, radio telephone just just has tangible minimizing aspect capacity seldom the user of ratio is benefited so that account for total number of users.
The benefit that is provided for progression price plan user is the information of identification phone region.Except that utilizing the broadcast addressing control messages, feature notice message can be configured to provide " demonstration " record.Phone has been indicated in the use of " demonstration " record, and feature notice content of message is the alphanumeric notation that will be presented on the phone.The particular letter digital massage that each base station sent is this regional information (for example " You are inzone 3. " or " Welcome to downtown " or " City Mall " etc.).Subsequently, the user can judge whether the call that begins from the specific region can cause that expense increases.By periodically sending feature notice message, just the change of zone state can be informed any this regional phone that enters.And phone does not need the transmission activity.And because use broadcast addressing, this message can be handled and show to those phones that only have message to be scheduled to.
It is the substitute use of feature notice message that Short Message Service (SMS) message can be used as.SMS message is mainly used in alphanumeric information is sent to radio telephone., can find among the SHORT MESSAGESERVICES FOR WIDEBAND SPREAD SPECTRUM CELLULAR SYSTEM at telecommunications industry association and the TIA/EIA/IS-637 of Electronic Industries Association the general description of SMS in the CDMA telephone system.Message can generate and send to phone by the base station at message center.Message also can generate in phone and send to message center by the base station.Send in this cycle that only relates to the area information from the base station to the phone.
The message that sends to phone from the base station can send in paging or traffic channel.The message format that sends to phone turns to as the defined data burst string of TIA/EIA/IS-95 message.When under the situation of feature notice message, message can be used as point-to-point directed message and sends to the individual user, also can be used as broadcast and sends to many phones simultaneously.
Operation of the present invention as shown in Figure 1.With reference to Fig. 1, show the part of wireless system 100.First base station 110 provides coverage on a side of zone boundary 130.Second base station 120 provides coverage on the opposite side of zone boundary 130.Manyly comprise that the element of each base station 110 or 120 is unimportant for this explanation, thereby hypothesis is included among the figure that represents each base station 110 or 120.
When mobile phone 141 during by the boundary scope between the zone, coverage will change between first base station 110 and second base station 120.For the given path 142 along bounds, mobile phone will repeatedly be crossed over zone boundary 130.In the time of in mobile phone 141 is in by the coverage of first base station, 110 definition, forward link 114 information and reverse link 112 information all will be supported by first base station 110.Equally, in the time of in mobile phone 141 is in by the coverage of second base station, 120 definition, corresponding forward link 124 and reverse link 122 channels all will be supported by second base station 120.
In existing embodiment, when crossing over zone boundary 130, register the regional location that upgrades mobile phone 141 by requiring mobile phone at every turn.When each mobile phone is crossed over zone boundary 130, the system parameters message that mobile phone 141 receives will be produced by different base stations.Adopt the situation shown in Fig. 1, mobile radio station 141 is worked in the coverage by 110 definition of first base station at first.Identify 110 regions, first base station from the system parameters message of first base station, 110 broadcasting.For the first time entering this zone and receive system parameters message on forward link 114 paging channel, mobile phone 141 sends registration message to first base station 110 on reverse link 112 access channels.First base station 110 responds by send the guide message that contains area information to mobile phone 141 on paging channel.When moved in the path 142 of mobile phone 141 in border region, it had just crossed over zone boundary 130.In case mobile phone 141 has been crossed over zone boundary 130, just provide coverage by second base station 120.Second base station 120 sends out the system parameters message of indication zones of different.In order to respond the regional different zone indication of having registered with mobile phone 141, mobile phone sends another registration message to second base station 120 on reverse link 122 access channels.Then second base station 120 sends to mobile phone 141 and contains the guide message of area information as response.The system parameters message situation that this indication mobile phone 141 registration rear regions change and the guide message of base station all can repeat when being sent in mobile phone 141 each leap zone boundaries 130.When in any preset time, registration situation and the telephone number of crossing over the zone boundary are multiplied each other, just the load that exists in the wireless system as can be seen is sizable.
The other mobile phone 150 and 160 of 130 work will cross along independent pathway 152 and 162 respectively along the zone boundary.When mobile phone 150 crosses path 152, it will cross over the zone boundary 130 twice, and require to register when its each crossing the boundary 130.Mobile phone 150 will receive the area information of the each registration of response.Equally, the 3rd mobile phone that crosses along independent pathway 162 will be required to send registration message, and receiving area information is responded when its each leap zone boundary 130.Reduce the capacity of access channel from the lasting registration message of mobile phone 141, and also reduced the capacity of paging channel from numerous guide message of base station 110 or 120.
By the present invention who in system, realizes, look back the situation of Fig. 1 again, can find that the present invention does not need mobile phone 141 to send.Notify message or SMS message but periodically send the broadcast address feature that contains the area information displayed record by each base station 110 or 120.The cycle of base station 110 or 120 repeated characteristics notice message is definite by system design, and usually in 5-15 scope second.When mobile phone 141 was in the specific region, it just received and processing feature is notified message and area information is shown to the user.When mobile phone 141 when advance in interregional borderline path 142, mobile phone 141 alternately receives the feature notice message from first base station 110 or second base station 120.The feature notice message that mobile phone 141 receives and handles is corresponding to the zone at its present place.Mobile phone 141 sends with regard to not carrying out active in order to know present zone.This has just reduced load on the access channel, and has preserved the electric weight in the phone.In addition, because base station 110 and 120 can use broadcast address message to replace guide message, thereby, just reduced the load on the paging channel.Can find that the other mobile phone 150 and 160 of working does not make the load in the system increase in the zone boundary.Each base station 110 or 120 sending zones notice message are irrelevant with the mobile phone 141,150 of crossing over zone boundary 130 and 160 numbers.Each mobile phone 141,150 and 160 shows the zone notice message corresponding to the base station 110 that regional coverage is provided and 120.
The method of in Fig. 2, having summarized regional notice.After beginning 200 these methods, the 204 sending zones notice message from the base station.The base station is not incident of response and sending zone notice message, but the transmission of the message desired unique regional informing movement that is the base station.The base station with message as the broadcast address message arrangement, so that can be simultaneously with a plurality of phones of this message directs.At determination step 208, the restriction of base station range in fact only allows to carry out routine processes when phone is in its coverage.Device is actual carries out this judgement, makes this judgement but limit by the physics coverage.If phone is not in the coverage that sends the base station, the signal that is sent will not receive and do not have phone because of too small and weak.Thereby program finishes 240.If there is phone in coverage, phone is with regard to receiving area notice message 210.At determination step 220, phone checks this message whether to point to this phone.This broadcast address of notifying message with the zone of upchecking is made comparisons with the presumptive address of storage in phone and is realized.If broadcast address is not the address that is stored in the phone, phone just judges that this message do not point to it.Thereby phone just abandons message 230, and program finishes 240.If broadcast address is consistent with the address in being stored in phone, phone is with regard to processing messages 224, and the content in the message is shown to user 228.Repeat if the method for Fig. 2 is the basis with the cycle, so, each phone in base station range all has continuous updating correct area information.
The description to preferred embodiment that the front provided is in order to make those skilled in the art can finish or use the present invention.For those skilled in the art, various modifications will be conspicuous to these embodiment, and not use under the creationary situation, can be applied to other embodiment in this defined General Principle.Like this, the present invention will be confined to the embodiment that goes out shown here, but meet with at principle and novel feature the wideest related category that this disclosed.
