Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by.
Embodiment 1
Embodiments provide a kind of method of user equipment differentiation access network, as shown in figure 1,
Methods described includes：
Step 101, analog core net send identification request to user equipment.
Home cell under searching eNodeB for the UE, in preparing to access during this home cell, need first with
ENodeB sets up wireless heterogeneous networks (RRC, Radio Resource Control) and connects.Work as eNodeB
Receive after RRC connect setting completes (Connection Setup Complete), between eNodeB and UE
Just establish RRC connect can transmit RRC information, can carry in RRC information Non-Access Stratum (NAS,
Non Access Stratum) signaling；So, receive RRC connect setting in eNodeB and complete (Connection
Setup Complete) just (IDENTITIY can be asked with off the net identification of analog core afterwards
REQUEST).
Need in the present embodiment to obtain the IMSI information of UE during UE accesses cell, and core net
It is to pass through eNodeB at random to send identification request to described UE, eNodeB is it cannot be guaranteed that in UE
The IMSI information of UE can be known during accessing cell in time, and eNodeB in existing setting only
It is to forward the identification response that this identification request and UE return, there is no parsing identification
Response obtains the function of IMSI information, therefore in the present embodiment, eNodeB needs analog core puberty off the net part to know
Do not invite and seek and receive and parse identification response acquisition IMSI information, so could be incited somebody to action according to IMSI information
The particular UE with specific IMSI information accesses specific cell.
The identification response that step 102, the described user equipment of reception return, and ring from described identification
Middle should extract and obtain IMSI information.
After user equipment receives the identification request of eNodeB analog core net transmission, will be considered that it is core
The identification request that heart net sends over, described user equipment will be according to the rule of associated network communication agreement
Fixed return includes the identification response of IMSI information.Described eNodeB receives described user equipment and returns
Identification response after, from described identification response extract obtain IMSI information.
Step 103, according to user's access strategy, when described IMSI information is target IMSI information, will
The corresponding user equipment of described target IMSI information accesses Target cell.
The present embodiment method is little in order to the particular UE with specific IMSI information is linked into specific target
Area.At this moment there are three kinds of situations：
The first situation is locally little under the above-mentioned eNodeB of extraction acquisition IMSI information in the present embodiment
Area is Target cell, and now, user's access strategy of described Target cell includes allowing access to have target
The target UE of IMSI information, forbid accessing the other users equipment without target IMSI information or
Person allow not have target IMSI information other users equipment access after force to be switched to Target cell with covering
The adjacent cell of lid；Then, according to described user's access strategy, it is target IMSI letter in described IMSI information
During breath, directly corresponding for described IMSI information described user equipment is accessed described Target cell；Described
When IMSI information is not target IMSI information, the corresponding described user equipment of described IMSI information is not allowed to connect
Enter described Target cell；Or it is allowed to the corresponding described user equipment of described IMSI information accesses described mesh
Mark cell, and send handover request message, institute to described Target cell with the adjacent cell covering after access
State handover request message and receive for adjacent cell and allow described user equipment to connect after described handover request message
Enter.
In the first scenario, Target cell only accesses the target UE with target IMSI information,
Other UE force to be switched to other cells after forbidding accessing or accessing.
Second situation is locally little under the above-mentioned eNodeB of extraction acquisition IMSI information in the present embodiment
Area is the same covering abutting subdistrict of described Target cell, and the subscriber policy of described Target cell is to forbid that user sets
Standby being directly accessed is accessed it is allowed to switch, from the same covering abutting subdistrict of described Target cell, the user equipment coming；
Described is to allow all user equipmenies to access with the subscriber policy covering abutting subdistrict, has target IMSI letter
The target UE of breath is forced to be switched to described Target cell after accessing；So, in described IMSI information
It is not during target IMSI information it is allowed to the corresponding described user equipment access of described IMSI information is described local
Cell；When described IMSI information is target IMSI information it is allowed to described target IMSI information is corresponding
User equipment accesses, and sends handover request message, described handover request to described Target cell after access
Message receives for Target cell and allows described target IMSI information corresponding after described handover request message
Described user equipment accesses.
In the latter case, target UE can access described Target cell same covering adjoin little
It is directly switch to described Target cell behind area.
The third situation is locally little under the above-mentioned eNodeB of extraction acquisition IMSI information in the present embodiment
Area can also be other cells, and described local user's access strategy includes allowing to access all user equipmenies, tool
The target UE having target IMSI information carries the target of acquisition in follow-up handover request message
Corresponding informance after IMSI information or the mapping of described target IMSI information；Therefore according to described subscriber policy,
When described IMSI information is not target IMSI information it is allowed to the corresponding described user of described IMSI information
Equipment accesses home cell；When described IMSI information is target IMSI information it is allowed to described IMSI believes
Cease corresponding described user equipment and access home cell, set needing cell to switch or in described targeted customer
For when moving to described Target cell coverage, send and carry target IMSI information or target IMSI
The handover request message of the corresponding informance after information MAP is to switching cell or Target cell；Described target IMSI
Information receives for Target cell and allows described target IMSI information corresponding after described handover request message
Described target UE accesses.
So, have target IMSI information target UE be linked into other cells after, can be in mesh
When mark user equipment moves to described Target cell coverage, the target with target IMSI information is used
Family equipment is linked into Target cell.Certainly in the process may target UE switched much individual other
Cell just can move to described Target cell coverage, in each handoff procedure, handover request message
In all carry the correspondence after the target IMSI information of this target UE or the mapping of target IMSI information
Information, so could send to Target cell and carries mesh when moving to described Target cell coverage
The handover request message of the corresponding informance after mark IMSI information or the mapping of target IMSI information, Target cell
The corresponding target UE of described target IMSI information is allowed to access after receiving described handover request message.
No matter home cell is Target cell, as the UE with target IMSI information, to enter into target little
The target zone in area, can be directly accessed or switch and be linked into described Target cell, and does not have IMSI
The UE of information then can not be linked into described Target cell, and this sample embodiment method just can be according to acquisition
The UE with target IMSI information is only linked into Target cell, solves prior art by IMSI information
Particular UE can not be linked into the problem of specific cell in (as scene 1 and scene 2).
Embodiment 2
Embodiments provide a kind of method of user equipment differentiation access network, as shown in Fig. 2
Methods described includes：
Step 201, analog core net issue identification request to UE.
Home cell under searching eNodeB for the UE, in preparing to access during this home cell, need first with
ENodeB sets up wireless heterogeneous networks (RRC, Radio Resource Control) and connects.Setting up RRC
During connection, UE can send RRC connection request (Connection Request) to eNodeB；eNodeB
RRC connect setting (Connection Setup) is sent to UE after receiving RRC Connection Request；
UE sets according to the parameter carrying in RRC Connection Setup after receiving RRC Connection Setup
Put UE, and send RRC Connection Setup Complete to eNodeB after the setup and (connect
It is provided with).
After eNodeB receives RRC Connection Setup Complete, between eNodeB and UE just
RRC information can be sent, Non-Access Stratum (NAS, Non Access in this RRC information, can be carried
Stratum) signaling；So, can after eNodeB receives RRC Connection Setup Complete
(IDENTITIY REQUEST) is asked with off the net identification of analog core.Described
IDENTITIY REQUEST is descending (DL, a Down Link) information transfer (Information
Transfer NAS signaling)：
The NAS code stream of this NAS signaling can be plaintext version or integrity protection form,
Here is not limited.Assume NAS signaling：IDENTITIY REQUEST is issued with plaintext version,
Should be then 07 55 01 (hexadecimals) according to its NAS code stream of existing NAS agreement.
Step 202, the identification response of reception described UE feedback.
After UE receives the identification request of eNodeB analog core net transmission, will be considered that it is that core net is sent out
The identification request brought, described UE will return according to the regulation of associated network communication agreement and comprise
There are the identification response (IDENTITY RESPONSE) of IMSI information, described IDENTITIY
REQUEST is the NAS of up (UL, Up Link) information transfer (Information Transfer)
Signaling.ENodeB receives the identification response of described UE feedback.
Step 203, true according to the NAS code stream in Access Layer NAS agreement and described identification response
Determine NAS code stream form.
Described NAS code stream form includes plaintext version or integrity protection form.
ENodeB is receiving the NAS signaling that above-mentioned UE returns：After IDENTITY RESPONSE,
The form of the NAS code stream in the described identification response receiving can be first determined whether.ENodeB needs to obtain
Know the high 4bit value of the 1st byte of its NAS code stream, if value is 0000, the form of this NAS code stream
For plaintext version；If value is 0001, the form of this NAS code stream is integrity protection form.These are all
Provide in existing NAS agreement, eNodeB can according to NAS agreement combine this NAS code stream Lai
Determine the form of this NAS code stream.
Step 204, described identification response is determined according to NAS agreement and described NAS code stream form
For comprising the identification response of IMSI code.
ENodeB is being established after RRC is connected with UE, can receive very eurypalynous NAS signaling, therefore
ENodeB receive UE transmission NAS signaling after it needs to be determined that whether this NAS signaling is to comprise IMSI
The identification response of code.
After eNodeB determines the NAS code stream form of this NAS signaling in step 203, can basis
In the NAS signaling of the multi-form that NAS agreement specifies, the implication of each heuristicimal code is determining this NAS
Signaling is IDENTITY RESPONSE, and is the identification response comprising IMSI code.
For the NAS signaling that NAS code stream is plaintext version, the 2nd byte value of its NAS code stream
Then determine that this NAS signaling is IDENTITY RESPONSE for decimal scale 86；And its NAS code stream the 4th
The low 3bit value of byte is 001 and determines that this NAS signaling is the identification response comprising IMSI code.
For the NAS signaling of integrity protection form, the 8th byte value of its NAS code stream is ten
System 86 then determines that this NAS signaling is IDENTITY RESPONSE；And its NAS code stream the 10th word
The low 3bit value of section is 001 and determines that this NAS signaling is the identification response comprising IMSI code.
Step 205, IMSI code is comprised from described according to described NAS agreement and described NAS code stream form
Identification response in extract obtain IMSI information.
ENodeB determine after this NAS signaling is the identification response comprising IMSI code it is possible to by
Corresponding relation between the IMSI information specifying according to NAS agreement and this NAS code stream, from NAS signaling
NAS code stream extracts IMSI information.
Below the idiographic flow of for example bright step 203-205：
Assume that the 16 system NAS code streams carrying in the NAS signaling receiving in step 202 are：07 56 08
49 06 10 56 34 12 40 49；1st byte 16 of this NAS code stream is entered to be made as 07, is converted into binary system
For 00000111, its high 4bit value is 0000, specifies to determine that this NAS signaling is bright according to NAS agreement
Civilian form.Specify for the NAS signaling of plaintext version according to NAS agreement, the of this NAS code stream
It is decimal scale 86 it is determined that this NAS signaling is IDENTITY that 2 bytes 16 enter to be made as 56 values
RESPONSE.And this NAS code stream the 4th byte 16 enters to be made as 49, being converted into binary system is 1001001,
Low 3bit value is 001 it is determined that this NAS signaling is the identification response comprising IMSI code.Determine
This NAS signaling be plaintext version comprise IMSI code identification response when, carried according to NAS agreement
Take IMSI number, such as：According to NAS agreement from the beginning of the 4th byte of NAS code stream, that is, in exclusion bracket
The high 4bit of code stream (07 56 08) the 49 06 10 56 34 12 40 49, the 4th byte be the 1st of IMSI
Numeral, as 4；For remainder bytes, low 4bit is first extracted to each byte, extract high 4bit afterwards；For example,
The low 4bit of the 5th byte is the 2nd numeral of IMSI, and as 6, high 4bit are the 3rd number of IMSI
Word, as 0；Last IMSI is extracted as：460016543210494.
Assume that the 16 system NAS code streams carrying in the NAS signaling receiving are：17 05 a6 07 b1 d0 07
56 08 49 06 10 17 00 56 42 45；1st byte 16 of this NAS code stream is entered to be made as 17, is converted into two
Enter to be made as 00010111, its high 4bit value is 0001, specify to determine this NAS signaling according to NAS agreement
For integrity protection form.Specify for the NAS signaling of integrity protection form according to NAS agreement,
It is decimal scale 86 it is determined that this NAS signaling is that 8th byte 16 of this NAS code stream enters to be made as 56 values
IDENTITY RESPONSE；And this NAS code stream the 10th byte 16 enters to be made as 49, it is converted into two and enters
It is made as 1001001, low 3bit value is 001 it is determined that this NAS signaling is the identity comprising IMSI code
Identification response.Determine the identification response comprising IMSI code that this NAS signaling is integrity protection form
When, IMSI number is extracted according to NAS agreement, such as：According to NAS agreement from the 10th word of NAS code stream
Section starts, i.e. code stream (17 05 a6 07 b1 d0 0,756 08) 49 06 10 17 00 56 42 in exclusion bracket
The high 4bit of 45, the 10th byte is the 1st numeral of IMSI, as 4；For remainder bytes, to each
Byte first extracts low 4bit, extracts high 4bit afterwards；For example, the low 4bit of the 11st byte is the 2nd of IMSI the
Individual numeral, as 6, high 4bit are the 3rd numeral of IMSI, as 0；Last IMSI is extracted as：
460017100652454.
Step 206, according to user's access strategy, when described IMSI information is target IMSI information, will
The corresponding user equipment of described target IMSI information accesses Target cell.
At this moment there are three kinds of situations：
A kind of situation is the home cell that above-mentioned extraction in the present embodiment obtains under the eNodeB of IMSI information
For Target cell, now, user's access strategy of described Target cell includes allowing access to have target IMSI
The target UE of information, forbids accessing the other users equipment without target IMSI information or permits
Force to be switched to Target cell with covering after the other users equipment access perhaps without target IMSI information
Adjacent cell；Then, according to described user's access strategy, when described IMSI information is target IMSI information,
The corresponding described user equipment of described IMSI information is allowed to access described Target cell；In described IMSI information
When not being target IMSI information, the corresponding described user equipment of described IMSI information is not allowed to access described mesh
Mark cell；Or it is allowed to the corresponding described user equipment of described IMSI information accesses described Target cell,
And sending handover request message to described Target cell with the adjacent cell covering after access, described switching please
Message is asked to be used for after adjacent cell receives described handover request message allowing described user equipment to access.
Example, as shown in figure 3, cell 1 is home cell；Cell 2 is with the neighbour covering with cell 1
Nearly cell；Wherein cell 1 is the Target cell that resource exclusively enjoys, and cell 2 is normal cells；Application scenarios are
High-level meeting scene, the UE0 of the such as full-time reporter of special user needs access cell 1 to exclusively enjoy resource, does not wish
Hope that being affected cell 1 by any other UE uses.
Now, Target cell is that user's access strategy of cell 1 can be for have target IMSI information be IMSI
Number for 460013511111111 full-time reporter UE0 access cell 1 exclusively enjoy resource, forbid access do not have
There are other UE of target IMSI information.
Cell 1 place base station and UE0 carry out the IMSI number that step 201-205 obtains described UE0, described
The IMSI number of UE0 is 460013511111111, then IMSI number is by cell 1 place base station
460013511111111 corresponding described UE0 access cell 1.
Cell 1 place base station and the IMSI of other UE UE1 as described in UE1 carries out the acquisition of step 201-205
Number, the IMSI number of described UE1 is 460013511122211, then cell 1 place base station does not allow IMSI
Number access cells 1 for 460013511122211 corresponding described UE1；Described UE1 is accomplished by continuing search for
The same covering adjacent cell-cell 2 of the cell that can access such as cell 1, cell 2 be normal cells it is allowed to
All UE access；So UE1 just and then can be linked into cell 2.
Now, home cell be cell 1 user's access strategy can also for allow with target IMSI believe
Breath is that the UE0 access cell 1 of the full-time reporter that IMSI number is 460013511111111 exclusively enjoys resource, permits
Force after other UE access perhaps without target IMSI information to be switched to the neighbouring little of the same covering of Target cell
Area.
Cell 1 place base station and UE0 carry out the IMSI number that step 201-205 obtains described UE0, described
The IMSI number of UE0 is 460013511111111, then IMSI number is by cell 1 place base station
460013511111111 corresponding described UE access cell 1.
Cell 1 place base station and the IMSI of other UE UE1 as described in UE1 carries out the acquisition of step 201-205
Number, the IMSI number of described UE1 is 460013511122211, then cell 1 place base station allows IMSI number
Access cell 1 for 460013511122211 corresponding described UE1；And it is same to described cell 1 after access
The adjacent cell covering is that cell 2 sends handover request message, and cell 2 is normal cells it is allowed to all UE
Access；So cell 2 allows described UE1 to access cell 2 after receiving this handover request message.
Second situation is locally little under the above-mentioned eNodeB of extraction acquisition IMSI information in the present embodiment
Area is the same covering abutting subdistrict of described Target cell, and now, the subscriber policy of described Target cell is to forbid
User equipment is directly accessed the user equipment it is allowed to come from the same covering abutting subdistrict switching of described Target cell
Access；Described is to allow all user equipmenies to access with the subscriber policy covering abutting subdistrict, has target
The target UE of IMSI information is forced to be switched to described Target cell after accessing；Then, according to described user
Access strategy, when described IMSI information is not target IMSI information it is allowed to described IMSI information corresponds to
Described user equipment access described home cell；When described IMSI information is target IMSI information, permit
Permitted the corresponding user equipment of described target IMSI information to access, and sent to described Target cell after access
Handover request message, described handover request message receives for Target cell and permits after described handover request message
Permitted the corresponding described user equipment of described target IMSI information to access.
Example, as shown in figure 3, cell 2 is home cell；Cell 1 is with the neighbour covering with cell 2
Nearly cell；Wherein cell 1 is the Target cell that resource exclusively enjoys, and cell 2 is normal cells；Application scenarios are
High-level meeting scene, the UE0 of the such as full-time reporter of special user needs access cell 1 to exclusively enjoy resource, does not wish
Hope that being affected cell 1 by any other UE uses.
Now, described Target cell be cell 1 user's access strategy be forbid that user equipment is directly accessed,
The user equipment coming from the same covering abutting subdistrict switching of described Target cell is allowed to access；Described Target cell
Same covering abutting subdistrict be that user's access strategy of cell 2 can have mesh for allowing all UE to access
Mark IMSI information is that the UE0 of the full-time reporter that IMSI number is 460013511111111 accesses after cell 2 by force
It is that cell 1 exclusively enjoys resource that system is switched to described Target cell.
Cell 2 place base station and UE0 carry out the IMSI number that step 201-205 obtains described UE0, described
The IMSI number of UE0 is 460013511111111, then IMSI number is by cell 2 place base station
460013511111111 corresponding described UE0 access cell 2.Because the user that home cell is cell 2 connects
Enter strategy for having the UE0 that target IMSI information is the full-time reporter that IMSI number is 460013511111111
Forcing after accessing cell 2 to be switched to described Target cell is that cell 1 exclusively enjoys resource.Therefore, base station is according to described
User's access strategy of cell 2, sends handover request message to cell 1, and such cell 1 receives this and cuts
After changing request message, just direct permission UE0 accesses cell 1, and such UE0 just can be with the resource of acceptance area 1
Exclusively enjoy.
Cell 2 place base station and the IMSI of other UE UE1 as described in UE1 carries out the acquisition of step 201-205
Number, the IMSI number of described UE1 is 460013511122211, then cell 1 place base station allows all UE
Access cell 2；I.e. then UE1 is accessed cell 2 by cell 2 place base station.IMSI due to described UE1
Number be 460013511122211, be not target IMSI information, therefore described UE1 remain in cell 2 and accepts
Service.
The third situation is locally little under the above-mentioned eNodeB of extraction acquisition IMSI information in the present embodiment
Area is other cells, then described home cell user's access strategy includes allowing all user equipmenies to access, tool
The target UE having target IMSI information carries the target of acquisition in follow-up handover request message
Corresponding informance after IMSI information or the mapping of described target IMSI information；Therefore according to described subscriber policy,
When described IMSI information is not target IMSI information it is allowed to the corresponding described user of described IMSI information
Equipment accesses home cell；When described IMSI information is target IMSI information it is allowed to described IMSI believes
Cease corresponding described user equipment and access home cell, set needing cell to switch or in described targeted customer
For when moving to described Target cell coverage, send and carry target IMSI information or target IMSI
The handover request message of the corresponding informance after information MAP is to switching cell or Target cell；Described target IMSI
Information receives for Target cell and allows described target IMSI information corresponding after described handover request message
Described target UE accesses..
Example, as shown in figure 4, described cell 3 is home cell；Cell 1 is with covering with cell 2
Cell；Cell 3 and cell 2 are neighbouring cell；Wherein cell 1 is the Target cell that resource exclusively enjoys,
Cell 2 and cell 3 are normal cells；Application scenarios are high-level meeting scene, the such as full-time note of special user
The UE0 of person needs access cell 1 to exclusively enjoy resource it is undesirable to be used by any other UE impact cell 1.
Now, access state can be arranged to not allow in the SIB2 of cell 1, the user of cell 3 accesses plan
Slightly can be for having the UE0 that target IMSI information is the full-time reporter that IMSI number is 460013511111111
Carry the target IMSI information of acquisition or described target IMSI information is reflected in follow-up handover request message
Corresponding informance after penetrating.
For the UE0 of full-time reporter, it is described that cell 3 place base station and UE0 carry out the acquisition of step 201-205
The IMSI number of UE0, the IMSI number of described UE0 is 460013511111111, then cell 3 place base station
IMSI number is that 460013511111111 corresponding described UE0 access cells 3, now described UE0 is not
In the coverage of cell 1, therefore UE0 will not be switched to cell 1 after the completion of accessing.When described UE0 moves
Move cell 1 coverage when, cell 3 can to described cell 1 send handover request message, this switching
The IMSI number of UE0 is carried in request message；Cell 1 is Target cell it is allowed to IMSI number is
460013511111111 UE0 accesses；Described in so cell 1 allows after receiving this handover request message
IMSI number is 460013511111111 UE0 access cell 1, and such UE0 just can be with acceptance area 1
Resource exclusively enjoy.
Here it should be noted that the UE0 for full-time reporter may need to switch that much individual other are little
Qu Caineng moves to the coverage that described Target cell is cell 1, in each handoff procedure, described
Its IMSI information such as IMSI number 460013511111111 all must be carried in handover request message；So,
When UE0 enters into the coverage of cell 1, cell 1 could be believed according to the IMSI in this handover request
Breath allows the UE0 that described IMSI number is 460013511111111 to access cell 1, and such UE0 is just permissible
The resource of acceptance area 1 exclusively enjoys.
For the UE such as UE1 of other users, cell 3 place base station carries out step 201-205 with UE1 and obtains
Obtain the IMSI number of described UE1, the IMSI number of described UE1 is 460013522222222, then cell 3
IMSI number is normally linked into cell 3 for 460013522222222 corresponding described UE1 by place base station,
Cell 3 resource is shared together with other common UE.When the coverage that described UE1 moves out cell 3 is entered
When entering the coverage to cell 2 and cell 1, cell 3 can send switching to described cell 1 or cell 2
Request message, does not carry the IMSI number of UE1 in this handover request message；Cell 1 is Target cell,
The UE0 that IMSI number is 460013511111111 is allowed to access；So cell 1 receives this handover request
Described UE1 is not allowed to access cell 1 after message, cell 2 is Target cell it is allowed to all UE access；
So cell 2 will allow described UE1 to access cell 2 after receiving this handover request message, and UE1 is from little
The handoff procedure that area 3 is switched to cell 2 is identical with prior art, repeats no more.
In the third situation, the corresponding UE of target IMSI information when switching to opposite end cell from this side cell,
The handover request sending can be S1 handover request (S1HANDOVER REQUIRED) or X2
Handover request (X2HANDOVER REQUEST)；Target IMSI information is carried in this handover request
Or the corresponding informance after the mapping of target IMSI information；Pass through protocol extension in described handover request message
Field, newly-increased agreement cell carry or are multiplexed Current protocol function field of not conflicting and carry described target IMSI
Information or target IMSI information mapping after corresponding informance be sent to opposite end cell be described switching cell or
Target cell；After opposite end cell extracts target IMSI information or is mapped according to described target IMSI information
Corresponding informance decomposite described target IMSI information after it is possible to plan is accessed according to the user of opposite end cell
Slightly processed.
When described IMSI information is IMSI number, for safety, can set in this side cell and opposite end cell
Put after reciprocally negotiating AES and the key of accreditation, this side cell to IMSI number according to AES and
Key is encrypted, and is decrypted acquisition IMSI number in opposite end cell.
Second situation and the third situation target UE are all that switching is linked into Target cell, except for the difference that,
In the case of second, described target UE is that to be switched to target from the same covering adjacent cell of described Target cell little
Area, target IMSI information can not be carried in the handover request message sending in handoff procedure；3rd
In the case of kind, described target UE is to be switched to Target cell from other cells, sends in handoff procedure
Handover request message needs to carry target IMSI information.
