Abstract
A portable messaging unit (130) roams within zones (105, 110, 115) of a communication system (100). The portable messaging unit (130) includes a processor (220) that determines whether the portable messaging unit (130) is registered in a current zone and a registration manager (235) for attempting to register at a time indicated by a retry algorithm when the portable messaging unit (130) is not registered in the current zone. An event detector (240) monitors unit operations to detect occurrence of a registration event, in response to which registration is attempted regardless of whether the time indicated by the retry algorithm has arrived.
Description
The present invention relates to messaging system, particularly portable information receiving and transmitting unit is the communication system of RT register traffic therein.
In the wireless communication system of routine, message is transmitted into the portable information receiving and transmitting unit that system user carries.When communication system is supported two-way communication, give information to portable information receiving and transmitting unit through a forward communication channels, through a reverse channel communication from portable information receiving and transmitting unit emission such as confirm and the registration request inbound messages, and handle this inbound messages by the rf control unit of control communication system work.
Registration request is usually by the emission of portable information receiving and transmitting unit, to represent in its given zone or zone that appears at system, so that message only offers portable information receiving and transmitting unit in this district.Yet usually because the low relatively portable information receiving and transmitting unit of power may be outside the scope of system receiver, inbound registration request always can not receive and be sent to rf control unit by system receiver.When registration was unsuccessful, inbound messages may not be launched in portable information receiving and transmitting unit.In addition, owing to can not accurately locate, often must in a plurality of districts, launch the predetermined message that receives by unregistered portable information receiving and transmitting unit to the position of portable information receiving and transmitting unit.The continuous emission of registration request can make portable information receiving and transmitting unit register as quickly as possible till the realization registration, thereby can realize the emission and the emission of effective outbound message of inbound messages.Yet, to launch the registration request from portable information receiving and transmitting unit in a large number and also will fill up inbound channel and exhaust battery rapidly, this situation is undesirable to the very valuable small portable information receiving and transmitting unit of battery capacity.
Therefore, need a kind of the management effectively by portable information receiving and transmitting unit emission registration request mode.
Fig. 1 is the block diagram that comprises the communication system in the zone that can roam therein according to portable information receiving and transmitting of the present invention unit.
Fig. 2 is the circuit block diagram that is used for the portable information receiving and transmitting unit of registering in the communication system of Fig. 1 according to the present invention.
Fig. 3 is the flow chart that the event detector work that comprises in the portable information receiving and transmitting unit of Fig. 2 according to the present invention is described.
Fig. 1 provides the block diagram of the wireless communication system 100 of the outbound data such as message through departures or forward communication channels to portable information receiving and transmitting unit (PMU) 130.Also can be by PMU130 through the inbound or inbound communication of reverse channel communication emission such as registration request or message authentication.Communication system 100 comprises the different business area that is called as zone 105,110,115, each district comprises one or more transmitters 120 that are used to launch outbound message, when inbound communication was supported in a specific region, this zone also comprised one or more reception of inbound receiver in communication 125 that are used for.Rf control unit (REC) 135 is coupled to the fixed system equipment in the zones of different 105,110,115, and for example transmitter 120 and receiver 125 are used to control the work of communication system 100.
Two-way PMU130 preferably is registered in the respective regions at its place.In case specific PMU130 is registered, can be only in the relevant range, rather than the predetermined message to PMU130 of emission in the whole system 100.In addition, can handle the inbound messages that receives from the PMU130 that the relevant range, registers by RFC135.On the other hand, when in the unregistered zone at its place of PMU130, its inbound messages always is not identified and handles.In some cases, unregistered PMU130 even can not launch inbound messages.In addition, owing to can not verify the position of unregistered PMU130, can only be at the outbound message of whole system 100 emission needles to PMU130, thus cause system resource utilization efficient low.
When PMU130 moves into zones of different, receive the realm identifier of this new region of expression, PMU130 responds this, and the registration request of a routine of emission is to be registered in the new region.When registering successfully, PMU130 receives and represents that this PMU130 is registered in the registration affirmation in its current region.Yet for example when PMU130 exceeded the scope of receiver 125, when the PMU130 edge region, or when occurring disturbing, the registration request of PMU may be lost by the receiver in the current region 125 sometimes.In this case, the indicated continuous attempts registration of time of retry algorithm that PMU130 will be in being programmed into PMU130.This retry algorithm can for example be indicated with fixed intervals, time cycle of 30 minutes for example, with variable interval, for example preceding ten minutes one minute once and after this per ten minutes once, or come attempts registration according to any calculating that other does not cause consuming excessively to the battery of PMU130 power supply.
PMU130 monitors the work of inner PMU, and response is such as receiving message through the departures channel, or receive will be by the appearance attempts registration of PMU130 through the specific registered situation of information of inbound channel emission and so on.The unsuccessful attempts registration that responds the appearance of registering events and carry out is not preferably disturbed the trial of carrying out according to retry algorithm.According to the present invention, PMU130 will be in the scheduled time of each retry algorithm attempts registration, and attempts registration when needed, promptly registers when the particular event that occurs wishing registering.For example, because PMU130 often will be to the affirmation of message emission that receives, along with the reception of message wishes to carry out attempts registration.Since not always to handle from the inbound emission of unregistered PMU130 or even send, before the emission inbound messages, also wish to attempt earlier registering.Like this, helping to manage registration attempts with balancing battery life-span, system resource and requires PMU130 to be operated in demand in the enrollment mode.
Next with reference to figure 2, the circuit block diagram of PMU130 is shown.PMU130 can be for example beep-pager or any other portable two-way radios equipment.PMU130 comprises and is used for transmitting and receiving the transceiver 205 of wireless signal in a usual manner and is used to handle the processor 220 that this wireless signal and being used to is controlled the work of PMU130.PMU130 can comprise a message memory 225 that is used to store the message of reception in addition, one is used to produce the notice mechanism 215 that notification signal receives with notification message, the display 210 of an information that is used to be shown to the user and be used to receive the controller 245 of user's input with operation or programming PMU130.Can comprise a data input unit (not shown), so that to PMU130 input information, for example programming information.
Comprise a device memory 230 among the PMU130, be used for the employed information of storage operation PMU130.Whether this information preferably includes the area identifiers of being used in a usual manner by processor 220, be registered in the current region in order to identification current region and definite PMU130.Device memory 230 is preferably also stored enrollment status information and the register information of being set routinely by processor 220, and launches the registration request according to these information.The registering events information stores is in device memory 220, with one or more registering events of indication triggering registration request emission.Can be by business operation person or user by controller 245, another data input device, or through wireless mode registering events information is programmed.The example of registering events comprises through departures channel reception message, through the information of inbound channel emission user input, by the special user's request of the operation registration of controller 245.Should be appreciated that, registering events different or that add can be programmed in the device memory 230 according to the present invention.
PMU130 also comprises an enrolment authority 235 that is used to manage the registration request that is not linked to the registering events generation.Enrolment authority 235 can begin registration at many reasons attempts, and for example response determines that PMU130 has entered your where order of ＂ of ＂ that a new region or response receive from system 100.For example, PMU130 can differently by the area identifiers that the area identifiers that comprises in the wireless signal of determining to receive is correlated with the zone of the last registration of PMU130 determine that it has entered new region.This information is preferably indicated by the enrollment status information of storage.
When registration was attempted getting nowhere, for example, when the registration that does not receive response registration request was confirmed, enrolment authority 235 setting enrollment status information were to represent unregistered this PMU130.In addition, enrolment authority 235 preferably keeps the record of an indication registration trial time.After this, as long as PMU130 is still unregistered, enrolment authority 235 is in the time attempts registration of being indicated by the retry algorithm of storage.As mentioned above, can preferably be set at the possibility maximum that makes successfully registration by the retry algorithm of controller 245 programmings and avoid consuming excessively the battery (not shown) simultaneously.In case successfully registered PMU130, enrolment authority 235 changes enrollment status information, has registered PMU130 with indication, and has indicated current zone by the area identifiers of for example storing current region.
According to the present invention, event detector 240 is included among the PMU130, is used to monitor the work of inner PMU, to detect the generation of registering events.Along with the generation of registering events, event detector 240 begins registration to be attempted, and irrelevant with the time that whether has reached the retry algorithm indication.Enrolment authority 235 and event detector 240 preferably include and are stored in firmware in the device memory 230 and that carried out by processor 220 at the duration of work of PMU130.Retry algorithm can be stored the part as the firmware that is used to implement enrolment authority 235.As an alternative, use can be carried out the hardware of equivalent operation can implement enrolment authority 235 and event detector 240, and retry algorithm can be stored in the memory device such as device memory 230 with the form of the equation that produces enrollment time or formula.
As the registering events information definition by programming, owing to can launch the registration request when needed, event detector 240 used according to the invention is favourable.Therefore, unregistered PMU130 will be according to retry algorithm, and when the registering events that takes place such as message sink in the official hour attempts registration.Therefore, the mode that this management registration is attempted has prevented that inbound channel is owing to the registration request that repeats is crowded, guarantee again simultaneously need do under the situation of registration for inbound communication, for example when PMU130 need launch the affirmation that receives message or when PMU130 need be to RFC135 or another PMU130 transmission inbound messages, register trial at PMU130.
As mentioned above, begin to register the time of request emission to avoid registering trial continuously and contingent excessive battery consumption if set enrolment authority 235.Yet, only use enrolment authority 235 may cause PMU130 after successfully registering trial not yet, to move to situation in the scope of system receiver 125 (Fig. 1) very soon.The result is, under the situation that does not have event detector 240, the PMU130 in the scope can whole remaining gap length or retry algorithm official hour cycle with unregistered pattern work, even PMU130 can successfully register and send inbound emission then.Event detector 240 has been by having solved this problem easily with enrolment authority 235 collaborative works, i.e. the incident of response programming is asked registration and with whether to reach the stipulated time irrelevant.
Fig. 3 is the flow chart of work of the event detector 240 of expression monitoring PMU130 internal work.In step 305, when when forward channel receives the information of the predetermined PMU130 of giving, or in step 310, when receiving by PMU130 through information that backward channel is launched, in step 320, event detector 240 determines in a usual manner whether PMU130 is registered in current region.Be appreciated that the emission of message sink and message only as the example of registering events, in step 315, the generation of any other registering events also can cause event detector 240 to determine in step 320 whether PMU130 is registered in the current region.To be appreciated that as those of ordinary skill in the art, in many ways detecting registering events.For example, but by Reference News's memory 225 or by receiving the reception of the ＂ input message ＂ signal detect-message that produces by processor 220.The user's input that receives by monitoring via controller 245 can detect the information that will launch.
In step 320, when definite PMU130 will register in the current region, owing to can realize inbound communication, event detector 240 did not take concrete action.Unregistered in current region the time as PMU130, event detector 240 starts enrolment authority 235 in step 325 and begins registration by emission registration request routinely and attempt.
In a word, above-described communication system comprises the zones of different that PMU can roam therein.Along with entering a zone, PMU attempts registering in this zone.Successful registration makes PMU can send the inbound communication of being handled in a usual manner by this system.Yet because the system receiver in this zone can not always correctly receive the lower powered relatively emission from PMU, registration is success always not.For example PMU may be outside scope, in the marginal zone or in the high interference district.In this case, PMU can be still with unidirectional mode work, through the higher departures emission of forward channel received power.Yet, in this zone, till the registration, needn't start inbound communication from the PMU in this specific region up to PMU.Therefore, according to retry algorithm able to programme emission registration request, so that attempts registration at the appointed time, and do not consume too many battery by PMU.
According to the present invention, also can respond the request of registering of registering events, and whether be that enrollment time is irrelevant with it.Registering events is programmable, and preferably includes the incident that triggering needs the action of inbound communication.For example, message sink will be a registering events usually, because PMU is with inbound affirmation of reception transmission of response message.In addition, the user's input information that is launched is formed a registering events, because these message will be sent so that system handles through backward channel by PMU.Other incident such as the simple user request also can be set at registering events.
Because aforesaid PMU responds the incident of regulation and registers trial at official hour, be convenient to the management registration and attempt, so that balance sends the necessity of inbound emission and the desirability that keeps battery capacity, and effectively utilize the channel capacity of system.
So far be appreciated that a kind of mode of being managed registration request emission by the portable information receiving and transmitting unit in the wireless communication system better is provided.
