Description

A kind of method and apparatus that upgrades and generate the MAIO hopping sequences

Technical field

The present invention relates to wireless communication field, particularly a kind of method and apparatus that upgrades and generate the MAIO hopping sequences.

Background technology

Along with the fast development of radio communication service, number of users becomes explosive growth with voice service.This has brought very big pressure for the operator of operator, particularly densely inhabited district.Therefore, how to effectively utilize existing base station and frequency resource more for more user provides more effective service, become one of problem that operator is concerned about most.

MUROS (Multi-User Reusing One Slot, time slot of multiuser multiplexing) has very high theoretical capacity gain, but owing to always forming strong jamming between two users that are assigned to same time slot, therefore, Ericsson has proposed the MUROS hopping scheme of a kind of MAIO of being called Hopping (Mobile Allocation Index Offset Hopping jumps mobile allocation index offset).The way of MAIO Hopping scheme is, the user in the residential quarter is divided into two set, and set 1 comprises that all are not in the user of MUROS pattern, and all I road users, gathers 2 and comprises every other user (namely all Q road user).The user of set 1 and set 2 uses same set of MA (Mobile Allocation, travel frequency is distributed) and same HSN (Hopping Sequence Number, HSN).The user of set 1 (3GPP TS45.002) in the conventional mode calculates MAI (Mobile Allocation Index, Mobile Allocation Index), the user of set 2 then has some change when calculating MAI, be exactly the MAIO that does not re-use fixed allocation, but MAI of every calculating just change MAIO.This mode is called MAIO Hopping, also can be described as " jumping MAIO ".

Prior art often adopts the method with the grouping of MAIO collection when concrete application the " jumping MAIO " technology, the MAIO collection in the residential quarter is divided into frequency hopping diversity group and fixed mode frequency hopping group.Can carry out OSC (Orthogonal Sub Channel, orthogonal sub-channels) pairing in the frequency hopping diversity group between all terminals of I road and all terminals of Q road, be about to two users and be multiplexed into a time slot, carry out the frequency hopping diversity operation.Terminal in the fixed mode frequency hopping group adopts the changeless traditional frequency hopping mode of MAIO to carry out the frequency hopping operation.In the call process, often great changes will take place for the residing channel circumstance of terminal.When the terminal in the frequency hopping diversity group moves to cell edge, because edge customer channel quality of living in is relatively poor, can't carry out matching operation, network must cut out it frequency hopping diversity group.Correspondingly, after edge customer moved to inside, residential quarter, and channel quality reaches OSC pairing thresholding, network can join this terminal in the suitable frequency hopping diversity group.The number of users that causes needs to participate in the frequency hopping diversity operation so constantly changes.Correspondingly, the frequency hopping diversity group MAIO number that need take also constantly changes.

At the MAIO set sizes scene of change takes place, prior art adopts network to send the mode of configuration signal simultaneously to the terminal in the frequency hopping diversity group usually, changes the MAIO hopping sequences of frequency hopping diversity flow process.Network will send MAIO hopping sequences update command for each terminal in the frequency hopping diversity group respectively, in this update command, identical MAIO sequence jump zero-time all is set, carries out the renewal of MAIO hopping sequences at synchronization to guarantee the terminal in the frequency hopping diversity group.

In realizing process of the present invention, the inventor finds that there is following problem at least in prior art:

When carrying out MAIO collection reprovision, if having only the success of part terminal reprovision, then can comprise the terminal of carrying out the frequency hopping diversity operation based on the MAIO collection of different sizes in the frequency hopping diversity group simultaneously.Because every kind of corresponding MAIO hopping sequences of MAIO set is arranged acquisition independently by the MAIO in this MAIO set, therefore, often conflict mutually between corresponding each the MAIO hopping sequences of the MAIO of different sizes set.In MAIO hopping sequences renewal process, if arbitrary terminal is upgraded failure, will cause the frequency that all terminals are used in the frequency hopping diversity group to conflict mutually, cause call drop when serious.

MAIO collection size shown in the network use table 6.2 is 3 " new MAIO hopping sequences ", this new MAIO hopping sequences is distributed to original terminal (M5 and M6) of second subchannel in the current frequency hopping diversity group, and make the branch of the branch number of this new MAIO hopping sequences of this original terminal correspondence and this former MAIO hopping sequences number identical.Wherein, original terminal (M5 and M6) reprovision success simultaneously also can the reprovision success of part terminal elder generation, and then other terminal of reprovision.Size shown in the table 6.5 is the mixing MAIO saltus step process of 2/3MAIO collection, it is the scene of part terminal (M5) the reprovision success of only original terminal, the designated use of M5 MAIO collection size is 3 o'clock sequence 0, and only still to use MAIO collection size be 2 o'clock sequence 1 to other terminal (M6) of original terminal.

Table 6.5

As can be seen from the above table, two MAIO hopping sequences that belong to different MAIO collection do not conflict mutually.For terminal M4, owing to added the frequency hopping diversity group, make M4 when carrying out the OSC matching operation, can obtain preferable channel quality again.Simultaneously, original terminal in the frequency hopping diversity group, because the adding of M6 has increased the chance of a random pair, the randomness of frequency hopping diversity is further strengthened, and has effectively increased the channel quality of original terminal.And in the prior art, if having only the success of part terminal reprovision, then tend to produce the phenomenon of frequency conflict, and had a strong impact on speech quality, cause call drop when serious.Therefore, present embodiment has improved speech quality, has solved the call drop phenomenon that causes owing to the frequency conflict in the prior art.

Then, network can be proceeded MAIO reprovision flow process at other terminal (M6) of original terminal.Size shown in the table 6.6 is the MAIO saltus step process of 3 MAIO collection, is the also scene of reprovision success of terminal M6, and the designated use of M6 MAIO collection size is 3 o'clock sequence 1.

Table 6.6

Then, when roaming to inside, residential quarter, terminal M3 can carry out OSC when pairing, also be that MAIO gathers when becoming big, network can be updated to 4 with the MAIO collection size of frequency hopping diversity group by the order of MAIO collection reprovision, and initiate the process of new renewal MAIO hopping sequences, MAIO collection size shown in specifically can use table 6.3 is 4 MAIO hopping sequences, this new MAIO hopping sequences is with respect to former MAIO hopping sequences, except comprising total branch (0 branch, 1 branch), also comprise non-total branch (2 branches, 3 branches); Renewal process is identical with the process that MAIO collection size is updated at 3 o'clock, and the total branch (0 branch, 1 branch) of new MAIO hopping sequences is distributed to original terminal (M5 and M6) of second subchannel in the current frequency hopping diversity group, and keeps its branch number constant; Can distribute to all terminals of original terminal simultaneously, also can distribute to the part terminal of original terminal earlier, and then distribute to other terminal of original terminal.

Size shown in the table 6.7 is the MAIO saltus step process of 3/4 mixing MAIO collection, is at first configuration successful of M5, and the designated use of M5 MAIO collection size is 4 o'clock sequence 0, and it is 3 o'clock sequence 1 that M6 still uses MAIO collection size.

Table 6.7

Size shown in the table 6.8 is the MAIO saltus step process of 4 MAIO collection, is the also scene of reprovision success of M6, and the designated use of M6 MAIO collection size is 4 o'clock sequence 0.

Table 6.8

Finish this more behind the new technological process, also can insert two new matched terminals (the newly-increased terminal of second subchannel) in the frequency hopping diversity group, carry out the non-total MAIOHSN=2 of branch of hopping sequences or 3 frequency hopping diversity operation, the branch of this second terminal correspondence number (2,3) is non-total branch with respect to the branch number (0,1) of former MAIO hopping sequences.

Accordingly, when carrying out MAIO collection rollback reprovision, i.e. when MAIO set diminished, renewal process was:

When the MAIO of the terminal correspondence in frequency hopping diversity group set diminishes, generate new MAIO hopping sequences, this new MAIO hopping sequences and former MAIO hopping sequences are to have quadrature; This new MAIO hopping sequences and this former MAIO hopping sequences comprise total branch, and this former MAIO hopping sequences also comprises non-total branch;

When the use of release terminal is when having branch, will with discharge terminal and use the total branch of this number identical new MAIO hopping sequences of the branch of branch, distribute to the terminal of the non-total branch that uses this former MAIO hopping sequences, otherwise, when discharge that terminal uses be non-total branch or the terminal of first subchannel time, this step can be omitted;

The terminal of giving second subchannel in the current frequency hopping diversity group with the total finger assignments of this new MAIO hopping sequences, and before keeping deserving in the frequency hopping diversity group branch of the terminal of second subchannel number constant.

For example: when terminal M2 discharges from the frequency hopping diversity group (M2 is when discharging terminal), then comprise M1, M3, M4 three terminals in the branch of I road in the frequency hopping diversity group, Q road branch comprises M5, M6 two terminals.It is that 3 MAIO collection can be carried out the frequency hopping diversity operation that this kind situation only needs size.When the frequency resource of residential quarter is in tension, it is 3 with the MAIO collection size reprovision of current frequency hopping diversity group that network can heavily be assigned flow process by the MAIO collection, and the total branch (0 branch, 1 branch) of new MAIO hopping sequences is distributed to the terminal (M5 and M6) of second subchannel in the current frequency hopping diversity group, and keep its branch number constant, namely in new MAIO hopping sequences, M5 still uses 0 branch, and M6 still uses 1 branch.From aforesaid MAIO collection expansion process as can be known, when carrying out MAIO collection rollback reprovision, even there is the part terminal to fail because of reprovision, because the MAIO hopping sequences of joining does not conflict mutually, terminal in the frequency hopping diversity group can be because of not skipping to same frequency yet, and causing mutually, conflict influences speech quality.Special, when the release terminal is M5, suppose that the Q road also has another terminal M7, use 2 branches of former MAIO hopping sequences, then 0 branch of new MAIO hopping sequences (M5 uses the branch number of branch at former MAIO hopping sequences) is distributed to M7, then, give M6 with 1 finger assignments of new MAIO hopping sequences again, its branch number is remained unchanged.
