Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further described in more detail.
Fig. 1 is that the LTE/WLAN dual-mode terminals that the embodiment of the present invention one provides return to the method flow diagram that LTE is netted from WLAN,
As shown in Figure 1, it is as follows：
Step 101：When LTE/WLAN dual-mode terminals access WLAN, the LTE module of the terminal is in the free time（Idle）Shape
State, which carries out the LTE cell measurements under Idle states, and each LTE cell measurement results are preserved preset duration
T。
LTE cell measurement results include：The persistent district of terminal, the measurement result of co-frequency neighbor cell, iso-frequency adjacent community, tool
Body parameter includes：Cell ID（cell ID）, cell signal strength such as：Reference Signal Received Power（RSRP, Reference
Signal Receiving Power）And Reference Signal Received Quality（RSRQ, Reference Signal Receiving
Quality）, may also include the measurement event met such as：Cell signal strength is less than a certain threshold value T0 seconds, and T0 is preset value.
The LTE cell measurement procedures that LTE module carries out under Idle states are same as the prior art, and LTE module can the period
Carry out LTE cell measurements to property.Wherein, the unit of T is usually the second.
Step 102：When LTE/WLAN dual-mode terminals need to disconnect WLAN connections, and access LTE network, actively to WLAN
Access point（AP, Access Port）Send quickly return LTE request messages, the message carry self identification and itself
LTE cell measurement results in the nearest T durations of LTE module.
Step 103：AP receives the quick return LTE request messages, passes the message to terminal in the resident of LTE network
The eNB of cell.
The persistent district for the terminal that AP can include according to the quick LTE cell measurement results returned in LTE request messages
Cell ID, learn terminal the persistent district of LTE network eNB.
Step 104：ENB receives the quick return LTE request messages, according to the message carry LTE cell measurement results,
And the type of service etc. of load, the support of each cell considers, and determines the LTE Target cells that terminal returns, is sent out to AP
It send and quickly returns to LTE confirmation messages, confirmation message carried terminal mark and LTE target cell informations.
In general, eNB can be comprehensive according to type of service of load, support of LTE cell measurement results and each cell etc.
Consider, selected in the LTE cells that measurement result includes one as LTE Target cells.
Wherein, LTE target cell informations include the frequency point of LTE Target cells, bandwidth, can also include LTE Target cells
System information block（SIB, System Information Block）When the content of 1 and SIB2, random access LTE Target cells
The targeting sequencing of use（preamble）Deng.Wherein, the preamble used when random access LTE Target cells is special for eNB
One or a set of code word for LTE/WLAN dual-mode terminal random access LTE networks of distribution.
Step 105：AP receives the quick return LTE confirmation messages, passes the message to terminal.
Step 106：Terminal receives the quick return LTE confirmation messages, the LTE target cell informations carried according to the message
Access LTE Target cells.
Here, if quickly returning to LTE confirmation messages carries the preamble used when random access LTE Target cells,
Terminal may be used the preamble to the eNB of LTE Target cells initiate random access, eNB according to the preamble it can be seen that
The random access is that LTE/WLAN dual-mode terminals are initiated, then can be with the priority access terminal.
In practical applications, step 104~105 could alternatively be：
ENB passes through paging according to the quick terminal iidentification returned in LTE request messages（paging）Mode will quickly return
It returns LTE confirmation messages and is sent to terminal, confirmation message carried terminal mark and LTE target cell informations, LTE Target cells
Information includes the frequency point of LTE Target cells, bandwidth, can also include the content of the SIB1 and SIB2 of LTE Target cells, connect at random
Enter the preamble etc. used when LTE Target cells.Wherein, if the current persistent district of LTE Target cells and terminal is identical,
LTE target cell informations are such as：Frequency point, bandwidth etc. can not issue, and after terminal receives the confirmation message, find not take in message
Band LTE target cell informations, it is determined that LTE Target cells are itself current persistent district.
Fig. 2 is the method flow diagram that LTE/WLAN dual-mode terminals provided by Embodiment 2 of the present invention return to that LTE is netted from WLAN,
As shown in Fig. 2, it is as follows：

LTE module carries out the LTE cell measurements under Idle states, and each LTE cell measurement results are preserved preset duration T.
This step 201 is identical as step 101.
Step 202：When the eNB of the current persistent district of terminal needs LTE/WLAN dual-mode terminals to return to LTE network immediately,
Or it is expected that when WLAN/LTE dual-mode terminals being needed to return to LTE network after M durations, is sent to terminal by the AP that terminal accesses
LTE cell measurement results request messages.
Step 203：Terminal receives the LTE cell measurement results request messages, and LTE cell measurements are returned to eNB by AP
As a result reporting message, the message carry the LTE cell measurement results in self identification and the nearest T durations of the LTE module of itself.
Alternatively, eNB can also active acquisition terminal LTE cell measurement results.Specially：
ENB sends paging message to terminal, the reason is that reporting LTE cell measurement results, terminal receives the paging in message
After the message, is established by random access and connect with the LTE of eNB, and connected by the LTE and report the LTE module of itself to eNB
LTE cell measurement results in nearest T durations.
Step 204：The industry of load, the support of the LTE cell measurement results and each cell that eNB is reported according to terminal
Service type etc. considers, and determines the LTE Target cells that terminal returns, and LTE target cell informations are carried and are quickly returning to LTE
AP is sent in confirmation message.
In general, eNB can be comprehensive according to type of service of load, support of LTE cell measurement results and each cell etc.
Consider, selected in the LTE cells that measurement result includes one as LTE Target cells.
LTE target cell informations include：The frequency point of LTE Target cells, bandwidth can also include LTE Target cells
The content of SIB1 and SIB2, the preamble used when can also include terminal random access LTE Target cells.
Step 205：AP receives the quick return LTE confirmation messages, passes the message to terminal.
If it is by the way of eNB pagings that terminal, which reports LTE cell measurement results, step 204~205 can replace
For：
The type of service etc. of load, the support of the LTE cell measurement results and each cell that eNB is reported according to terminal
Consider, determines the LTE Target cells that terminal returns, controlled by dedicated radio resources（RRC, Radio Resource
Control）The mode of signaling issues to terminal and quickly returns to LTE confirmation messages, which includes：Terminal iidentification and LTE
Target cell information, LTE target cell informations include the frequency point of LTE Target cells, bandwidth, can also include LTE Target cells
SIB1 and SIB2 content, the preamble that uses when can also include terminal random access LTE Target cells.
If LTE Target cells are exactly the current persistent district of terminal, eNB can not be issued to terminal quickly returns to LTE
Confirmation message.Terminal is after reporting LTE cell measurement results, if not receiving any disappearing of eNB returns in default response time
Breath, then can determine that LTE Target cells are itself current persistent district.
Step 206：Terminal receives the quick return LTE confirmation messages, the LTE target cell informations carried according to the message
Access LTE Target cells.
