Description

The present invention relates to the field of communication technology, and in particular, processes network indications in an interworking process between a network controlled LTE network (Long Term Evolution) network and a wireless LAN (WLAN, Wireless Local Area Network). Regarding devices, methods and communication systems.

Five possible application scenarios are described for 3GPP R12 network assisted LTE network and WLAN interworking (also known as RA-IWK), including the following three types: The scenario is included.

(1) When a user equipment (UE, User Equipment) uses an LTE network in the coverage of an LTE radio access network (RAN, Radio Access Network), it enters the coverage of a WLAN access point (AP, Access Point);
(2) When the UE uses the WLAN in the overlapped coverage of the LTE RAN and WLAN AP, it leaves the coverage of the WLAN AP; and (3) the UE leaves the LTE network in the overlapped coverage of the LTE RAN and the WLAN AP. When using, all or part of the LTE traffic is transferred to the WLAN (Steering).

Regarding RA-IWK, the following agreements have been achieved, for example:
If a UE in a connected state (ie, RRC_CONNECTED) in an LTE network receives dedicated network instructions (eg, dedicated thresholds), the UE should use the dedicated network instructions, otherwise the UE , Common network instructions (eg broadcasted thresholds) should be used; and
When the UE is idle (ie, RRC_IDLE), the dedicated network instructions should be maintained and used within a predetermined period T after entering the idle state, and then the common network instructions should be used, UE. Releases a dedicated network instruction when performing a handover or cell reselection, and the dedicated network instruction is not provided within the Radio Resource Control (RRC) connection release period (provided only by RRCConnectionReconfiguration).

Similar to RA-IWK, dedicated network instructions are used in the LTE network of 3GPP R13 network control and WLAN interaction (also called RC-IWK). For example, a dedicated threshold (eg, payload) can be used, and the UE can find a WLAN network that matches the criteria based on the given threshold and according to the same criteria as RA-IWK. You may use the newly introduced dedicated message to carry the Traffic Steering (TS) command, which directly indicates the target WLAN. As for the idle R13 UE, a common network instruction, a dedicated network instruction or a new dedicated TS instruction can be used, which may be controlled by the network side or may depend on the UE. good.

Regarding RC-IWK, the following agreements have been achieved, for example:
When the base station provides a set of APs for the UE (eg, labeled by SSID, HESSID or BSSID, etc.) and supports interworking, the WLAN roaming mechanism uses these APs, ie. The UE can move transparently to the base station, and the base station can control the cross group movement of the UE, for example, based on the measurement report provided by the UE. ;
A WLAN mobility set is a set of one or more SSIDs / HESSIDs / BSSIDs, and the UE is that movements between APs that belong to the same WLAN movement set are transparent to the base station, ie. , UE does not notify the base station of information about movement within the WLAN mobile set; and all APs belonging to the same WLAN mobile set share a WLAN termination (WT, WLAN Termination), which is the control plane. (CP, Control Plane) and User Plane (UP, User Plane) endpoints, and the UE is connected to at most one WLAN moving set at any given time.

Differences between RC-IWK and RA-IWK include the following, for example:
(1) Tighter network control is required in RC-IWK;
(2) In RC-IWK, the new TS instruction can also be a network instruction under the connection mode. That is, a UE in the connected state may receive a dedicated threshold and / or a new TS instruction, including information on whether it will be offloaded to the WLAN and information on the target WLAN;
(3) In addition to the target WLAN information, the network instructions may also include information on the WLAN mobile set.

It should be noted that the above-mentioned introduction of the background technique is for the purpose of clearly and completely explaining the technical proposal of the present invention and for those skilled in the art to easily understand it. These proposals are described as part of the background art of the present invention and should not be construed as well known to those of skill in the art.

The inventor discovered the following. That is, in the following scenario, that is, in RC-IWK, only one PDN connection is maintained between the packet data network gateway (P-GW, Packet Data Network GateWay) and the UE, or all PDN connections are WLAN. Under the scenario of being moved to, we found that the UE goes idle after performing traffic steering according to a conventional mechanism (eg RA-IWK).

However, in RC-IWK, the UE may re-enter the connected state (for example, due to the base station considering load balancing), which causes, for example, the UE that does not want to use the LTE network to re-enter the LTE network system. It may appear that the UE is steered back and forth between the LTE network and the WLAN, or the UE makes a round trip transition between idle and connected states. This can result in unnecessary signaling idles and traffic interruptions, which can reduce network performance and user experience. Therefore, it is necessary to solve the problem of how to apply the RC-IWK mechanism and how to process the network instructions in the RC-IWK mechanism.

The embodiments of the present invention provide a method of processing network instructions, which are applied to RC-IWK procedures. In this embodiment, the explanation will be given from the base station side.

FIG. 1 is a diagram showing a method of processing a network instruction in an embodiment of the present invention. As shown in FIG. 1, the method of processing the network instruction includes the following steps.

Step 101: When the base station receives the user equipment context release instruction transmitted by the MME, the user equipment context release instruction includes release cause information indicating that the user equipment traffic is steered from the LTE network to the WLAN. Determine if it will be;
Step 102: The base station reconnects to the user equipment if the user equipment context release instruction contains the release cause information indicating that the traffic is steered from the LTE network to the WLAN. Is started to keep the user device in the connected state.

In this example, the difference from the RA-IWK procedure is that the user equipment context release instruction sent by the MME of the core network contains release cause information that "indicates that UE traffic is steered from the LTE network to the WLAN". If so, even if the network detects that the UE has no traffic in the LTE network for a long period of time, or if the MME instructs the UE to release an RRC connection, the base station will , The RRC connection release procedure can be started without starting, but only the RRC connection reset procedure can be started to keep the UE in the connected state.

In this embodiment, the user equipment context release instruction may include a user equipment context release instruction message (that is, a UE CONTEXT RELEASE COMMAND message) on the S1 interface, and the release cause message may include the user equipment context release instruction. It may include a cause value added to the message to indicate that the traffic is steered from the LTE network to the WLAN.

For example, one new cause value, for example, "traffic offloading from LTE to WLAN", may be added to the UE CONTEXT RELEASE COMMAND message on the S1 interface. You may also add new abnormal conditions, i.e. record that the base station decides to hold the RRC connection, continue to service this UE, and UE CONTEXT RELEASE COMPLETE. Do not respond to messages.

However, the present invention is not limited to this, and for example, the user device context release instruction may be another message, and the release cause message may be another description or the like, that is, A specific implementation method may be determined according to the actual situation.

In this embodiment, only a signaling radio bearer (SRB, Signaling Radio Bearer) for delivering measurement reports and / or subsequent dedicated network instructions between the UE and the base station may be maintained, for example, SRB1. Further, the activation cycle in the discontinuous reception (DRX) mechanism of the UE may be set to be larger than a predetermined threshold value, for example, to be larger than the value specified in the current standard. May be set to, which allows the UE to use a relatively long DRX and save energy.

This keeps the UE connected rather than idle if the user equipment context release instruction contains release cause information indicating that the UE traffic is steered from the LTE network to the WLAN. By doing so, for example, it is possible to prevent a UE that does not want to use the LTE network from being steered by the LTE network system again.

FIG. 2 is another diagram showing a method of processing a network instruction in an embodiment of the present invention. As shown in FIG. 2, the method of processing the network instruction includes the following steps.

Step 201: The base station detects if the UE has traffic in the LTE network within a long period of time;
Step 202: Receive the user device context release instruction sent by MME;
Step 203: The base station determines whether the user equipment context release instruction contains release cause information indicating that the UE traffic is steered from the LTE network to the WLAN, and includes the release cause information. If so, perform step 204, and if the release cause information is not included, perform step 205;
Step 204: The base station initiates a reconnection procedure for the UE to keep the UE connected;
In this embodiment, the base station can start only the RRC connection reconfiguration procedure without starting the RRC connection release procedure for the UE, for example, the UE maintains only SRB1.

Step 205: The base station initiates a connection release procedure for the UE to cause the UE to go idle.

In this embodiment, the base station can reuse the conventional scheme after the UE has entered the idle state. Also, when necessary, the base station may further establish SRB1 for the UE.

Step 206: The base station establishes an SRB for delivering measurement reports and / or subsequent dedicated network instructions for the UE.

In this embodiment, only SRB1 may be established, which may transmit, for example, a measurement report of the UE (or subsequent possible network instructions) or a new network instruction (eg, paging). Used for transmission.

For example, the establishment of SRB1 may be initiated when the UE moves out of the WLAN mobile set or reselects a new cell, or when the network (eg, a base station) sends a new network instruction. May be started. Among them, the application layer of the UE (AS layer, for example, the RRC layer) can report to the upper layer (for example, the non-access layer, that is, the NAS layer), and the upper layer of the UE establishes the RRC connection. However, it may be requested to include (carry) the established cause in it, and the established cause is, for example, "integration with non-3gpp RAT".

As can be seen from the above embodiment, when the base station receives the user equipment context release instruction transmitted by the MME, the user equipment context release instruction indicates that the user equipment traffic is steered from the LTE network to the WLAN. If the release cause information shown is included, the user device is maintained in the connected state. This allows processing on how to apply the RC-IWK mechanism and how to process network instructions in the RC-IWK mechanism, for example, UEs who do not want to use the LTE network can again process the LTE network. You can prevent the system from being steered.

In this embodiment, the timer corresponding to the dedicated network instruction is, for example, the timer T350, but the present invention is not limited to this, and may be, for example, another new timer.

Step 304: After stopping the timer corresponding to the dedicated network instruction, the user apparatus uses the broadcast common network instruction instead of using the dedicated network instruction.

In this embodiment, a new trigger condition for stopping the timer, for example, T350, for example, "UE is moving out of the WLAN mobility set" may be added. Once the T350 is down, the UE does not use dedicated network instructions (including dedicated thresholds and / or TS instructions), but uses broadcast common network instructions.

As shown in FIG. 3, the method of processing the network instruction may further include the following steps.

Step 305: The user equipment requests the base station to establish a signaling radio bearer for delivering measurement reports and / or subsequent dedicated network instructions.

In this embodiment, in order to allow the UE to enter the connected state from the idle state when the UE moves out of the WLAN moving set, and to transmit only SRB1 for measurement reports and subsequent possible dedicated network instructions. May be established.

Among them, when the UE leaves the WLAN moving set, the application layer of the UE (AS layer, for example, RRC layer) reports to the upper layer (for example, NAS layer), and the upper layer of the UE makes an RRC connection. Established and requested to include the cause of establishment, the cause of establishment is, for example, "integration with non-3gpp RAT".

Although the UE has been described above from the connected state to the idle state, in the present embodiment, the UE may directly stop the timer 350 when leaving the WLAN moving set under the idle state.

FIG. 4 is another diagram showing a method of processing a network instruction in an embodiment of the present invention. As shown in FIG. 4, the method of processing the network instruction includes the following steps.

Step 401: Stop the timer corresponding to the dedicated network instruction when the user appliance leaves the WLAN mobile set.

Step 402: After stopping the timer corresponding to the dedicated network instruction, the user apparatus uses the broadcast common network instruction instead of using the dedicated network instruction.

As shown in FIG. 4, when the user device leaves the WLAN mobile set, the processing method may further include the following steps.

Step 403: The user appliance requests the base station to establish a signaling radio bearer for delivering measurement reports and / or subsequent dedicated network instructions. For example, request to establish only SRB1.

As can be seen from the above embodiment, when the user device moves out of the WLAN travel set, the user device stops the timer, eg T350, and / or only SRB1 is established, thereby how RC-IWK. It can handle how to apply the mechanism and how to handle the network instructions in the RC-IWK mechanism, for example, UEs that do not want to use the LTE network will not be steered to the LTE network system again.
