Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
In embodiments of the present invention, by user terminal (User End, hereinafter to be referred as UE) when flag bit that the PICH (Paging Indicator Channel, Page Indication Channel) of its paging residential quarter, place detected is unregistered sign, initiatively initiate registration; Make mobile communication system that sign is revised as registered symbol; Mobile communication system only copies to paging information the registered paging of respective user terminal residential quarter, to send paging information to the user when paging occurs.Like this, thus initiatively initiated to register the probability that reduces out of reach by the user; And mobile communication system must not send to paging information whole lane place, user place, thereby reduced transmission paging information quantity, improved the operational efficiency of system and the paging quality in the high capacity communication situation, increases the user to the degree of belief of network.
In mobile communication system, paging is used for seeking and calling out the registered user's terminal that moves freely that those are distributed in the diverse location district, and user terminal responds and complete signaling or the business procedure that network is initiated under various states.In order to reduce power consumption of terminal, terminal needn't be understood all beep-page messages, as long as understand its corresponding beep-page message.In mobile communication system, terminal is by understanding a paging indicator corresponding with it in PICH (Paging IndicatorChannel, Page Indication Channel), to determine whether to need to receive the beep-page message of back.
In each PICH message, paging indicator Pq sends with LPI=2,4,8 symbols, and wherein LPI is defined as the paging indicating length.The numerical value of paging indicator Pq in each PICH message is provided by the paging indicating length, and they are all both known concerning high-level signaling.Following table 1 shows the paging indication mapping that prior art provides:
Table 1
The bit that table 1 shows paging factor reality under prior art and the corresponding situation of state that whether receives the beep-page message of back.Consider in table 1 the paging indicator 0,0 ..., 0} and 1,1 ..., also have other state outside these two states of 1}.As: when the LPI=2,4 kinds of states are arranged, and { 00}, { 01}, { 10}, { { 01}, { this two states of 10} does not use 11} in fact.In embodiments of the present invention, regulation paging indicator is { 0, represent during the 1} state that current calling residential quarter user terminal corresponding to this paging indicator of the inside is registered sign, namely have at least one to complete registration to user that should the paging indicator in the paging residential quarter; Wherein the position PI of the paging indicator of user terminal is determined by PI=(IMSI div 8192) mod Np; The IMSI full name is International Mobile Subscriber IdentificationNumber, and its Chinese name is international mobile subscriber identity; Np is the number of the paging indicator that contains in each PICH.When the paging indicator is { to be expressed as the unregistered sign of this user terminal during 0,0}; Be { to be expressed as the registered sign of this user terminal during 0,1} at the paging indicator.
At LPI=4,8 situation can be analogized according to aforesaid way.Be defined as follows respectively:
During LPI=4 with { 0,1,0,1};
During LPI=8 with { 0,1,0,1,0,1,0,1};
Be expressed as the registered sign of user terminal corresponding to this paging indicator of the inside, current calling residential quarter.The paging indicator 0,0 ..., the 0} state representation is the unregistered sign of user terminal corresponding to this paging indicator of the inside, current calling residential quarter.So just defined paging indicator corresponding in the Page Indication Channel that user terminal uses its paging residential quarter, place as its registered symbol position.
Those skilled in the art will appreciate that the free position that can define in paging indicator corresponding to user terminal except prior art is used in the state that sign received or do not receive the back paging information is as the registered sign of user terminal; Also can define in PICH the out of Memory position as UE registered mark position whether.
Position PI=(IMSI div 8192) mod Np due to the paging indicator, therefore might there be a plurality of UE to use the paging indicator of same position, when a UE registers, other UE just need not register again so, this situation can reduce the times of registration of UE, but can not leak any one UE of registration.
Fig. 1 shows the method flow of the registered paging in mobile communication system that the embodiment of the present invention provides.For convenience of description, only show part related to the present invention here.
In step S101, when the user detects flag bit in the PICH of its paging residential quarter, place and is unregistered sign, initiate registration.
At the UE that just starts shooting or be in the IDLE attitude at any time by detecting the value of its paging indicator, if the bit that its corresponding paging indicator detected for 0,0 ... .0} just illustrates that network side do not set this registered symbol in the present residing paging of UE residential quarter.At this moment, UE initiatively re-starts registration.The probability of UE out of reach when this mode of initiatively initiating to register by UE is conducive to reduce paging.
In step S102, mobile communication system is revised as registered sign with the flag bit in the PICH under this user terminal in the paging residential quarter, and starts sign and remove timer.
In registration process, the channel indicator that the RNC of mobile communication system (Radio Network Controller, radio network controller) will call out the PICH under this user in the residential quarter is revised as registered sign.Enable simultaneously sign and remove timer, sign is removed timer and is unregistered sign to constantly the channel indicator of its PICH being remodified in the future.
Those skilled in the art will appreciate that it can be that time setting in advance according to actual conditions is long that sign is removed the timing time setting of timer, can be also that the time of unified setting is long.
In step S103, mobile communication system when sending beep-page message, copy beep-page message to the respective user terminal registered and sign remove timer not then paging residential quarter, make message send to user terminal.
In mobile communication system, but RNC safeguards paging UE in each residential quarter; Dynamically generate paging set of cells corresponding to each UE, the paging residential quarter that this set is registered sign by the paging indicator flag bit of PICH corresponding to paged UE forms.Namely in real time the paging residential quarter of user terminal registration is joined in its corresponding paging set of cells, and the registered but sign of user terminal is removed timer paging residential quarter then remove out its corresponding paging set of cells.Like this when sending beep-page message, send to UE by the paging residential quarter after can fast beep-page message being copied.
Mobile communication system is carried out copying of beep-page message by the paging cell set that RNC is corresponding according to paged UE when sending beep-page message, can fast beep-page message be copied to the paging cell set.By each paging residential quarter, beep-page message is sent to the user again, the user carries out normal signaling or service response process after receiving paging.
The cost of the method for above-mentioned paging is that mainly UE initiates in registration, and the situation analysis that can produce the initiation registration for UE is as follows:
UE begin to start shooting use and static situation under, need to initiate to register in initial registration or interval certain hour, the cost of the system of registration is the same with existing technology in this case.
When UE is in mobile situation, if in talking state, need to carrying out the residential quarter so this time, UE switches, it is registered can carrying out set to the flag bit of paging indicator simultaneously in switching, just paging can be found UE; If UE is at the Idle state, under this state, UE need to do cell reselection, just register unique might ging wrong when being gravity treatment, paging delivery in the time of gravity treatment, but in the time of the UE gravity treatment, be exactly not accept paging in practice, thus can not cause call out less than consequence.
Movement at dense city, there is the concept of a paging residential quarter this inside, above is either way that UE registers for the first time in other words, if after having registered, do not need to re-register in the time of sign removing timer, the situation of repetition or registration repeatedly can't occur thus.
In sum, the cost of the method that the embodiment of the present invention provides is mainly on first registration, and this cost is very light; And advantage is significantly, especially to reducing the paging time delay, reduces the paging collider and has larger improvement, can improve the paging quality in the high capacity communication situation, strengthens the user to the degree of belief of network.
