Description

Quick paging control method, system, functional entity and terminal equipment

technical field

The present invention relates to mobile communication technology, in particular to a quick paging control method, a control system, a paging control functional entity on the access network side and terminal equipment.

Background technique

At present, 3G (3 ^rd generation, third generation) mobile communication technology is gradually mature and commercially available. 3GPP2 (3 ^rd generation partnership project 2, third generation mobile communication cooperation project organization 2), CDMA2000 (one of the 3G standard technologies, is formulated by 3GPP2 Standards, including: CDMA, Code Division Multiple Access, wideband code division multiple access system), 1XEV-DO (Evolution Data Optimization, data optimization evolution) can further provide competitive wireless access systems in the next few years. However, in order to maintain competitiveness in the next decade or decades, it is necessary to introduce new wireless access technologies. At present, the industry has reached a preliminary consensus on the evolution of 3GPP2 air interface technology, which is divided into two stages. The first stage adopts multi-carrier EV-DO technology, and more consideration is given to compatibility. It is only a short-term evolution project; the second stage is AIE (Air interface evolution , air interface evolution) is to introduce more advanced technologies, such as OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology, MIMO (Multi Input Multi Output, multiple input multiple output) technology, etc., can greatly improve The spectrum efficiency and peak rate of the wireless access system are long-term evolution plans of the 3GPP2 standard.

Paging is a common technology in the wireless communication system, that is, the remote fixed station or mobile terminal calls the AT ((Access Terminal, access terminal) in the idle state in the wireless communication system, that is, the AT in the wireless communication system acts as the called The AT in the idle state mainly works in the following two working modes: continuous monitoring and time slot mode. In the continuous monitoring mode, the AT continuously monitors the messages of the control channel. In this state, the network side can send a search for the AT call, the AT listens to the paging and responds to the paging; in the slot mode, the AT alternately enters the sleep and wake-up states, and the AT turns off the transmitter to sleep in the sleep state, and the network side does not send paging to the AT. The quick paging message to AT from the far end will be placed in the buffer and wait for the wake-up time of AT before sending the quick paging message to it; while the AT will monitor the overhead message and quick paging message when it wakes up, the network side can Send a page to AT anytime.

When the network side sends a quick paging message to an AT in the idle state, it will use an AT identification number for paging. This identification number is unique within a geographical area, and the quick paging message will be in the location area. broadcast under all sites.

Paging technology is generally divided into one-step paging and two-step paging according to the steps of paging. One-step paging is to directly carry the unique identification number of the paged AT in the paging message; two-step paging is to realize the paging of the AT in two steps, first use all or part of the AT (When paging two or more ATs), paging with the identification information, and then using the complete identification information of the ATs to perform paging. The first step is also called quick paging. The two methods have their own advantages and disadvantages. The former is simple to implement, but consumes more power for ATs that do not have paging messages but continue to monitor the paging channel; the latter requires overhead, but for ATs that are not matched with quick paging, they do not need to receive The second step is paging, so it can save power.

Referring to Fig. 1, in the existing quick paging technology, AN (Access Network, access network) sends all or part of the identification information of the AT to be paged in the superframe Preamble (leader) as identification information, and the identification information may be AT's 32bit (bit) UATI (unicast access terminal identifier, unicast access terminal identifier), or AT's 32bit SessionSeed (session seed, which is an identification number that AT generates independently according to a random algorithm and reports to AN) , it may also be a random number calculated according to UATI or SessionSeed, such as the user hash value obtained through a hash function (hash function) operation (the user hash value is also stored in the AT).

AT monitors the quick paging message, if it can match the identification information in the message, AT generates a quick paging received primitive, and then receives the paging message on DCH (Dedicated Channel, dedicated channel); if AT cannot match The identification information in the quick paging message, the AT will no longer monitor the paging message on the DCH.

As shown in Figure 2, the quick paging message sent in the superframe Preamble is mainly divided into two parts, with a total of 35 bits. First, the first part carries a field for indicating the number of pagings, with a total of 3 bits. The second part is used for Carry the identification information of the paging terminal device, a total of 32 bits. When AN sends a quick paging message to AT, it is divided into the following situations:

1. If the AN receives only one paging from the remote end, the AN directly uses the UATI of the AT to page the AT;

2. If the AN receives two pages from the remote end, the AN uses the lower 16 bits of the user hash value as the identification information to quickly page the corresponding AT;

3. If the AN receives three pages from the remote end, the AN uses the lower 10 bits of the user hash value as the identification information to quickly page the corresponding AT;

4. If AN receives four pages from the remote end, AN uses the lower 8 bits of the user hash value as the identification information to quickly page the corresponding AT;

5. If the AN receives five pages from the remote end, the AN uses the lower 6 bits of the user hash value as the identification information to quickly page the corresponding AT.

The value of the field indicating the number of quick paging entries is 111, which is temporarily reserved and unused.

It can be seen from FIG. 2 that when the value of the paging number field is 011, there are still 2 bits of reserved fields; when the value of the paging number field is 101, there are still 2 bits of reserved fields.

When paging two or more ATs, since the identification information of each AT carried in the first step of paging is a few bits intercepted from the tail of the user hash value, these intercepted tail bits may often match multiple AT, all matched ATs will be triggered to listen to the second step of paging. These ATs actually only include one AT that really wants to be paged, and the rest are irrelevant ATs. This phenomenon that irrelevant ATs are triggered is called paging. Paging conflicts, paging conflicts will mainly cause power consumption of irrelevant ATs, reducing user experience.

In the existing quick paging technology, the LSB (Least significant bit) of the user hash value of multiple ATs is equal and the possibility of listening to the quick paging message in the same superframe preamble still exists, so no matter what It is difficult to completely avoid paging conflicts even if measures are taken. For example, when there are 3 quick paging messages to be sent, the low 10bits of the 3 user hash values should be sent, and all ATs with the same low 10bit user hash values will generate fast paging messages. Paging received primitive.

Detailed ways

In order to reduce paging conflicts generated in quick paging when paging two or more ATs at the same time, the present invention provides the following optimization methods:

With reference to the prior art, intercept the first information field at the same position in the identification information of each AT to be paged as the identification information of the corresponding AT, and then compare whether each first information field is unique, if unique, the first information field is sufficient Distinguish all the ATs to be paged, so referring to the prior art, combine the first indication information and each intercepted first information field according to the agreed first order and send it in the quick paging message;

If some or some first information fields intercepted do not have uniqueness, that is, at least one group of equal first information fields appears, then the second information field is intercepted from at least one AT identification information to be paged, to ensure The validity of the information, the second information field should be intercepted from a position outside the corresponding first information field, and then, the second indication information, all intercepted second information fields, each unique first information field and each One of a group of non-unique first information fields is combined and sent in the quick paging message according to the agreed second sequence.

The optimization of the technical solution of the present invention lies in that only one of the equal first information fields is sent, so that certain bits can be vacated, and the vacated bits are used to carry more identification information of at least one AT to be paged, namely When the second information field uses the total length of the first information field plus the second information field for matching, the probability of matching multiple ATs is reduced, so as to achieve the purpose of reducing paging conflicts.

What needs to be explained in the above-mentioned technical scheme is:

The AT identification information corresponds to the unique identification number UATI of the AT. It can be directly the UATI of the AT, or the SessionSeed of the AT, or a random number generated according to the UATI or SessionSeed. Number such as user hash value;

The first information field is part of the AT identification information intercepted from the first specified position in the AT identification information. The first specified position is, for example, the tail, the head, or any position in the middle of the AT identification information. The present invention does not limit the first position as long as AN and It is enough for the AT parties to agree clearly. The length of the first information field is determined according to the number of ATs to be paged and the length of the second step in the quick paging message, such as the format shown in Figure 2. The present invention does not limit a specific Format;

The second information field is part of the identification information located outside the first specified position in the AT identification information, for example, the part of the identification information adjacent to the first information field, according to the number of corresponding ATs and the vacancy after omitting the remaining first information field The output bit is determined, and the present invention also does not limit a specific format;

The interception object of the second information field can be the identification information of any one or more ATs, the number and the length of each second information field can be flexibly selected according to the vacant bits, and the present invention does not limit a specific model;

The first indication information indicates that all the first information fields are unique, but the agreed combination order corresponding to the first information fields needs to be set according to the number of terminal devices that are paging at the same time, and the AT performs corresponding analysis according to the agreed format. The first indication The information may include the first part of the existing quick paging message;

The second indication information may include a set of corresponding indication information, respectively indicating different situations where the first information fields are equal. The AT's FIFs are equal, and even two sets of equal FIFs may occur; as a result of the combination of the number of groups of equal FIFs that may occur and/or the number of equal FIFs in each group Many, so you can select some of the cases with high probability of occurrence, ignore the cases with very small probability of occurrence, or even consider only the case where the two first information fields are equal in each case, and take all the remaining cases into consideration. All of the first information fields are considered unique;

Each agreed combination order includes the arrangement order of indication information and identification information, the arrangement order of the unique first information field, the position of the non-unique first information field, and the positions of the second information field, which need to be clarified Given the permutation and combination in each case, AN generates a quick paging message according to the corresponding permutation and combination, and AT reads and reassembles the information according to the corresponding permutation and combination.

According to the number of ATs to be paged, there are many situations where the first information field is equal, but in each case, the corresponding indication information, the second information field, and the agreed combination sequence of the first information field can be given , it is only necessary to set the correspondence table between the specific indication information and the agreed combination order of the AT identification information on both sides of the AN and the AT at the same time, then the AN side will use the correspondence table to generate a quick paging when performing the first step of paging. After receiving the quick paging message, the AT uses the correspondence table to analyze the quick paging message, and then performs matching according to the analysis result.

The specific processing flow on the AN side is shown in Figure 3, including the following steps:

S301. Intercept the first information field in the identification information of each AT to be paged;

S302, comparing whether each first information field is unique, if so, execute step S303; otherwise, execute step S304;

S303. According to the correspondence table, combine corresponding indication information and related information fields, where the related information fields include each first information field, and then perform step S305;

Indication information includes two parts, the first part is for example as shown in Figure 2, is the first indication bit of the number of existing ATs to be paged, and the existing mode has 3 bits in total; the second part is used to indicate each AT set by the present invention The second indication bit identifying the combination mode of the information.

S304. Intercept the second information field of at least one AT to be paged, and combine the corresponding indication information and related information fields according to the correspondence table. The related information fields include all second information fields, all unique first information fields and each Set one of the non-unique first information fields, then perform step S305;

S305. Generate a quick paging message carrying combination information;

S306. Broadcast a quick paging message.

The processing flow on the AT side is shown in Figure 4, including the following steps:

S401. Receive a quick paging message;

S402. Determine the number of ATs to be paged according to the first indication bit, that is, the number of AT identification information combined in this quick paging message;

S403. Determine the combination order of the relevant information fields according to the second indication bit and the correspondence table;

S404. Directly read or reorganize the identification information of each AT according to the combination sequence;

If the first information fields are all unique, read the identification information of each AT directly from the corresponding bit; otherwise, after reading the relevant information fields, reorganize the identification information of each AT according to the combination sequence;

S405. Use its own corresponding identification information to match the identification information of each AT in the quick paging message;

S406. Perform a corresponding operation according to the matching result.

If the match is successful, then generate and send the quick paging received primitive; otherwise, the AT will continue to stay in the idle state, if the AT works in the slot mode, it will go to sleep, if the AT works in other modes, it will continue to monitor the quick paging channel.

Each combination sequence corresponds to a format of the quick paging message. The format of the quick paging message corresponding to each combination sequence is described below. Since there are many specific implementations of the technical concept of the present invention, only examples are given here. It is not intended to limit the protection scope of the present invention.

1. Quickly paging 2 ATs

The specific implementation method is shown in Table 1 below, where the category indicates whether the first information field is equal:

Table 1.

different 001 00 15+15 The identification information length of each AT is 15bit Equivalent 001 01 15+8+7 First intercept 15bit from the identification information of each AT, if they are equal, then intercept 8bit and 7bit from the identification information of each AT respectively, then the identification information of the two ATs are 23bit and 22bit respectively

A variety of implementation methods can also be derived, one of which is shown in Table 2 below:

Table 2.

different 001 0 15+15 The identification information length of each AT is 15bit, with 1bit left Equivalent 001 1 15+8+8 First intercept 15 bits from the identification information of each AT, if they are equal, then intercept 8 bits from the identification information of each AT, then the identification information of the two ATs is 23 bits respectively

Other similar implementation manners are not listed exhaustively.

2. Quickly paging 3 ATs

The specific implementation method is shown in Table 3 below, for example:

table 3.

different 010 00 10+10+10 The identification information length of each AT is 10bit 2 of them are equal 010 01 10+2+10+4+4 First intercept 10 bits from the identification information of each AT, if two of them are equal, then intercept 2 bits from the unique AT identification information to form 12-bit identification information; never unique 2 AT identification information 4 bits are intercepted respectively, and 14 bits of identification information can be formed respectively 3 all equal 010 10 10+7+7+6 First intercept 10 bits from the identification information of each AT, if all are equal, then intercept 7, 7, and 6 bits from the identification information of each AT, then the identification information of each AT is 17, 17 and 16 bits respectively

The combination sequence of 10+10+5+5 can also be adopted, that is, the 10-bit first information field is first intercepted from the identification information of each AT, and if two of the first information fields are equal, then the two ATs that are not unique The 5-bit second information field is intercepted from the identification information of the AT, and the identification information of the three ATs are 10, 15 and 15 bits respectively.

Still referring to Figure 2, for example, if AN has 3 paging messages to send, that is, it needs to quickly page 3 ATs, it should send the lower 10 bits of the hash values of the 3 users, but if there are 2 ATs’ lower 10 bits If they are exactly the same, it is meaningless to put two completely equal fields, because one such field can make all ATs with the same low 10-bit user hash value generate quick paging received primitives. Therefore, the improvement measure is to use the reserved 2 bits to indicate whether there are two paging LSBs that are exactly the same. The specific implementation has the following two optional methods:

Method 1: Use 00 in the reserved field to indicate that the three pages are different, then 2+10+10+10; use 01 to indicate that the two pages are the same, then use 2+10+10+5+5, where The first 5 indicates the 10+5 low 15-bit user hash value of one paging; the second 5 indicates the 15-bit user hash value of another 10+5 paging. Method 2: Use 00 in the reserved field to indicate that the three pages are different, then 2+10+10+10; use 01 to indicate that there are two pages that are the same, then use 2+20+10, where 20 represents the first The lower 20 bits of the first page, and 10 represents the lower 10 bits of the second and third pages.

According to different implementation manners, the identification information of one, two or three of the terminal devices may be lengthened.

3. Paging 4 ATs

The specific implementation method is shown in Table 4 below, for example:

Table 4.

Category The first indicator bit (3bit) The second indicator bit (1bit) Combination sequence of each information field (30bit) Description of combination order of each information field Category The first indicator bit (3bit) The second indicator bit (2bit) Combination sequence of each information field (30bit) Description of combination order of each information field different 100 00 8+8+8+8 The identification information length of each AT is 8bit 2 of them are equal 100 01 8+2+8+2+8+2 +2 First intercept 10 bits from the identification information of each AT, if two of them are equal, and then intercept 2 bits from the identification information of the two ATs that are not unique, then the identification information of the four ATs are all 10 bits 3 of them are equal 100 10 8+2+8+4+4+4 First intercept 10 bits from the identification information of each AT, if 3 of them are equal, and then intercept 4 bits from the identification information of the 3 ATs that are not unique, then the identification information of the 4 ATs are 10, 12, 12, 12bit 4 all equal 100 11 8+2+5+5+5+5 First intercept 10 bits from the identification information of each AT, if all are equal, and then intercept 5 bits from the identification information of each AT, then the identification information of the four ATs is all 15 bits

There are many similar implementation methods, as shown in Figure 2. For example, if there are 4 quick paging messages to be sent, the lower 8 bits of the 4 user hash values should be sent, but if there are 2 ATs whose lower 8 bits are completely same, it is meaningless to put two completely equal fields, but there are no reserved fields available, so there are three methods available:

Method 1. Save 2 bits from it and become 2+8+8+7+7. For example, 00 of this 2 bits means that the 4 paging lines are different, then 8+8+7+7; 01 means this Two paging LSBs are equal, then 8+8+7+4+3, the first 2 8bits represent 2 pagings, 4bits represent the LSB of a paging 7+4 total 11bit user hash, the second A 3bit indicates the LSB of the 7+3 total 10bit user hash of another page;

Method 2. Use the reserved value of 111 in the first 3 bits expressing the number of quick paging messages to indicate that there are two LSBs in the four quick paging messages that are equal. Specifically, it can be designed as 8+8+8+4+4, The first two 8s represent 2 pages, the first 4 represents the LSB of the 8+4 total 12-bit user hash of one paging, and the second 4 represents the 8+4 total 12-bit user hash of another paging LSB;

Method 3. Extended from the second method, the reserved value of 111 in the first 3 bits expressing the number of quick paging messages is still used to indicate that there are two LSBs in the four quick paging messages that are equal. Specifically, it can be designed as 12+12+8, the first two 12s represent the lower 12 bits of the two quick pages, and the last 8 represent the lower 8 bits of the two pages.

According to different implementation manners, the identification information of 1, 2, 3 or 4 terminal devices may be lengthened.

4. Paging 5 ATs

The specific implementation method is shown in Table 5 below, for example:

table 5.

Category The first indicator bit (3bit) The second indicator bit (2bit) Combination order of each information field (30bit) Description of combination order of each information field Category The first indicator bit (3bit) The second indicator bit (2bit) Combination sequence of each information field (30bit) Description of combination order of each information field Category The first indicator bit (3bit) The second indicator bit (2bit) Combination sequence of each information field (30bit) Description of combination order of each information field different 101 00 6+6+6+6+6 The identification information length of each AT is 6bit 2 of them are equal 101 01 6+6+6+6+3+3 First intercept 6 bits from the identification information of each AT, if two of them are equal, and then intercept 3 bits from the identification information of the two ATs that are not unique, the identification information of the five ATs is 6, 6, and 6 respectively. , 9 and 9bit 3 of them are equal 101 10 6+3+6+3+6+2+ 2+2 First intercept 6 bits from the identification information of each AT, if 3 of them are equal, then intercept 2 bits from the identification information of the unique 3 ATs, and intercept 2 bits from the identification information of the 3 ATs that are not unique, Then the identification information of the five ATs are 9, 9, 8, 8 and 8 bits respectively 4 all equal 101 11 10+6+3+3+3+3 First intercept 6 bits from the identification information of each AT, if all are equal, then intercept 2 bits from the identification information of the only 1 AT, and intercept 3 bits from the identification information of the 4 ATs that are not unique, then the 5 ATs The identification information is 10, 9, 9, 9 and 9bit respectively

If it is limited by the number of second indication bits, since the probability that the first information fields of the five ATs are all equal is very low, it can be ignored and processed as if all the first information fields are not equal.

There are many similar implementation methods, still refer to Figure 2. For example, there are 5 paging messages to be sent, and the lower 6 bits of the 5 user hash values should be sent, but if the lower 6 bits of 2 ATs are exactly the same , it is meaningless to put two completely equal fields, so the reserved 2 bits are also used to indicate whether there are any LSBs in the five pagings that are equal. The specific implementations are as follows:

Method 1. For example, 00 means that the 5 paging lines are different, then 2+6+6+6+6+6, 01 means that the LSBs of two of them are equal, then 2+6+6+6+6+ 3+3, the first 3 6s represent 3 paging, the first 3bit represents the user hash of a paging 6+3 with a total of 9 bits low, and the second 3bit represents another paging 6+3 with a total of 9 bits low user hash;

Method 2: Use 00 in the reserved field to indicate that the 5 pagings are different, then 2+6+6+6+6+6, 01 means that the LSBs of two of them are equal, then 2+8+8+8 +6, the first three 8s represent the lower 8 bits of the three quick pages; 6 represent the lower 6 bits of the two pages.

According to different implementation manners, the identification information of 1, 2, 3, 4 or 5 terminal devices may be lengthened.

Another example to illustrate the specific selection of the situation that needs to be processed according to the probability of occurrence, for example, in the above embodiment, in the case of five 6bit fields:
