Embodiment
Divide for above-mentioned existing LTE network the problem existing in stream mechanism, the embodiment of the present invention provides a kind of technical scheme of network shunting, can be applied to the LTE network that comprises eNB and UE.In technical scheme, eNB monitors LTE network traffics, and sends the message of carrying out WLAN connection for triggering UE to UE; UE receives carrying out for triggering UE after the message of WLAN connection that eNB sends, can determine whether to carry out WLAN connection according to this message, provides support for realizing not affecting on LTE network performance basis to the shunting of LTE network.
Wherein, the message of carrying out WLAN connection for triggering UE that eNB sends to UE carries the LTE network traffic conditions that eNB monitors, and this message can be carried out WLAN connection for suggestion UE.UE receives after this message, can determine whether to carry out WLAN connection according to this message.
Below in conjunction with the accompanying drawing in embodiments of the invention, the technical scheme in embodiments of the invention is clearly and completely described, obviously, the embodiments described below are only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of embodiments of the invention protection.
As shown in Figure 1, the schematic flow sheet of a kind of network shunt method providing for the embodiment of the present invention, can comprise the following steps:
Concrete, in embodiments of the present invention, eNB can monitor in real time to LTE network traffics, and sends and trigger the message that UE carries out WLAN connection to UE according to the LTE network traffic conditions monitoring.For example, when the LTE network traffic conditions monitoring as eNB reaches predetermined threshold value, eNB can send the message that carry out WLAN connection for triggering UE to UE.
Wherein, when eNB monitors LTE network traffics, the LTE network traffics that monitor can for the actual loading flow of LTE network and LTE network can load the ratio of total flow, determine LTE network traffics grade according to this ratio, and send and trigger the message that UE carries out WLAN connection to UE according to this LTE network traffics grade.
Wherein, can carry out flow grade division in eNB side to LTE network in advance, for example, when the actual load flow of LTE network and LTE network can load the ratio of total flow while being not more than first threshold (as 30%), determine that LTE network traffics grade is the first order (30% is first order upper limit threshold); The ratio of total flow that can load when the actual load flow of LTE network and LTE network is greater than first threshold, but while being not more than Second Threshold (as 50%), determines that LTE network traffics grade is the second level (50% is second level upper limit threshold); The ratio of total flow that can load when the actual load flow of LTE network and LTE network is greater than Second Threshold, but while being not more than the 3rd threshold value (as 80%), determines that LTE network traffics grade is the third level (80% is third level upper limit threshold).ENB can monitor in real time to LTE network traffics, and reaches the first/bis-/tri-threshold values when monitoring LTE network traffics, time, send the message of carrying out WLAN connection for triggering UE of carrying current LTE network traffics grade to UE.Wherein, first threshold < Second Threshold < the 3rd threshold value.
Preferably, in the time that eNB monitors LTE network traffic conditions and reaches threshold value (or first threshold or Second Threshold or the 3rd threshold value), eNB can further judge that the number of times that LTE network traffic conditions reaches threshold value (or first threshold or Second Threshold or the 3rd threshold value) is odd number or even number, or, judge that LTE network traffic conditions is rise and reach threshold value (or first threshold or Second Threshold or the 3rd threshold value), still declines and reaches threshold value (or first threshold or Second Threshold or the 3rd threshold value); When judged result is odd number or rising while reaching threshold value (or first threshold or Second Threshold or the 3rd threshold value), determine and need to carry out network shunting, and send the message of carrying out WLAN connection for triggering UE to UE; When judged result is even number or decline while reaching threshold value (or first threshold or Second Threshold or the 3rd threshold value), determine and do not need to carry out network shunting, do not send the message of carrying out WLAN connection for triggering UE to UE.
Wherein, when eNB carries out the message of WLAN connection to UE transmission for triggering UE, can send this message to the whole UE that are connected with self, also can only send this message to the part UE being connected with self.For example, in the time that eNB monitors LTE network traffics and reaches first threshold, eNB can select 20%(as random selection from the UE being connected with self) UE send the message of carrying out WLAN connection for triggering UE; In the time that LTE network traffics reach Second Threshold, eNB can select 50% UE to send the message of carrying out WLAN connection for triggering UE from the UE being connected with self.
Concrete, in embodiments of the present invention, when UE receive that eNB sends when triggering UE and carry out the message of WLAN connection, the LTE network traffic conditions that UE can monitor according to the eNB carrying in this message, self WLAN access account of the history and the electric weight situation of self determine whether the message of carrying out WLAN connection for triggering UE (whether needing to carry out network shunting) that response receives, and in the time being judged as YES, UE can carry out WLAN connection (detecting and attempt connecting wlan network), and in the time being successfully connected to WLAN, can be by the service distributing on part LTE network to wlan network, otherwise UE can not respond this message.
Further, in embodiments of the present invention, UE need to carry out after network shunting definite, can return to the wlan network situation detecting for feeding back UE to eNB, and the message of the wlan network connection state of UE.
Correspondingly, eNB receives the wlan network situation detecting for feeding back UE that UE returns, and after the message of the wlan network connection state of UE, need again to send when triggering the message that UE carries out WLAN connection (as current LTE network traffics reach higher threshold value) to UE when determining, eNB can carry the wlan network situation that each UE of receiving detects, the wlan network connection state of each UE in this message.In the time that UE receives this message, UE determines whether self has set up and be connected with wlan network, if be judged as YES, UE feeds back the wlan network situation detecting, and the WLAN that the wlan network connection state of the LTE network traffics that monitor according to eNB, the wlan network situation that each UE detects, each UE upgrades self (for example connects, in the time that LTE network traffics grade raises, UE can increase network shunting dynamics, by the service distributing on more LTE network to wlan network); Otherwise the wlan network connection state of the LTE network traffic conditions that UE monitors according to eNB, the wlan network situation that each UE detects, each UE carries out WLAN connection.
Wherein, the positional information that can also carry UE for feeding back the message of wlan network connection state of wlan network situation that UE detects and UE that UE returns to eNB, this positional information can be used as other UE in follow-up flow process carries out the reference of WLAN connection.For example, when UE receive the wlan network connection state that carries the wlan network situation that each UE detects, each UE that eNB sends and each UE positional information when triggering UE and carry out the message of WLAN connection, the WLAN that can directly select near the UE of self-position to connect connects, and do not need the scanning of carrying out WLAN to detect, improve network shunting efficiency.
Wherein, in embodiments of the present invention, the wlan network situation that UE detects can include but not limited to: the AP(Access Point that UE detects, access point) total quantity, the SSID(Service Set Identifier of each AP, service set), the BSID(Base Station Identity Code of each AP, base station identity code), the place channel of each AP, the load state of each AP;
The wlan network connection state of UE can include but not limited to: the load state of the BSID of the SSID of the AP that whether UE is connected with AP, UE connects, the AP that UE connects, the AP place channel that UE connects, AP that UE connects.
Carry out the message of WLAN (wireless local area network) WLAN connection for triggering UE and pass through radio resource control RRC signaling or media interviews control MAC layer signalling; Or/and,
For the message of wlan network connection state of feeding back wlan network situation that UE detects and UE by radio resource control RRC signaling or media interviews control MAC layer signalling.

Wherein in ACK_WiFi message, carry respectively wlan network situation and wlan network connection state that each UE detects.
Step 205, eNB receive the ACK_WiFi message that UE1, UE2 and UE3 return, and in the time that eNB monitors LTE network traffic conditions and rises and reach 80%, eNB is to UE1, UE2, UE3 and UE4 transmission WiFi_offloading message.
Wherein, the LTE network traffics grade of carrying in this WiFi_offloading message is C, and in this WiFi_offloading message, also carries wlan network situation and wlan network connection state that UE1, UE2 and UE3 detect.
In this embodiment, in the time that UE receives the WiFi_offloading message that the flow grade that carries is B, UE1, UE2 and UE3 adjust the network shunting dynamics of self, and UE4 determines need to carry out network shunting.
Step 206, UE1, UE2 and UE3 adjust the network shunting dynamics of self, and UE4 carries out WLAN connection, and UE1, UE2, UE3 and UE4 all return to ACK_WiFi message to eNB.
