Title: processing means indicative of the network, a method and a communication system

FIELD

[0001]

The present invention relates to communication technologies, and particularly relates to a long term evolution (LTE, Long Term Evolution) is in a network control / wireless local area network (WLAN, Wireless Local Area Network) interoperability during processing apparatus indicated by the network, a method and a communication system.

Background technique

[0002]

In the network-assisted 3GPP R12 LTE / WLAN interoperability (may be referred to RA-IWK), the recording of the five possible scenarios, including the following three scenarios:

[0003]

(1) In the user equipment (UE, User Equipment) in an LTE radio access network (RAN, Radio Access Network) coverage into the WLAN access point when using LTE (AP, Access Point) range;

[0004]

(2) UE in the overlapping range of the LTE RAN and WLAN AP, the WLAN AP leaves the coverage of the WLAN use; and

[0005]

All or part of the business (3) UE in the overlapping range of the LTE RAN and WLAN AP, UE of LTE is used is transferred to WLAN.

[0006]

For RA-IWK reached agreement as follows, for example:

[0007]

In the LTE UE is in a connected state (i.e. the RRC_CONNECTED) if the private network receives an indication (e.g., dedicated thresholds) then the UE should use the private network indicated otherwise, the UE shall apply the public network indication (e.g. broadcasted thresholds);

[0008]

UE in the idle state (i.e. RRCJDLE), in should be maintained from entering the idle state period of time T, and application-specific network indication, then it should use the public network indication; UE releasing the dedicated network indication when a handover or a cell reselection; and specific network indication is not provided (provided only by the RRCConnectionReconfiguration) during a radio resource control (RRC, radio resource control) connection release.

[0009]

In the 3GPP R13 LTE / WLAN interoperable network control (it may be called RC-IWK) in the RA-IWK as a private network is also indicated. For example, using a dedicated threshold value (e.g. load), the UE based on a threshold given find standard WLAN network in accordance with the RA-IWK same criteria; in addition can also be used to carry traffic transfer newly introduced (TS, Traffic Steering) Command dedicated message, which directly indicates the target WLAN network. For R13UE in the idle state, the indication can apply the public network, a private network or a new dedicated TS indicating a command, which may be controlled by the network side or may also depend on the UE.

[0010]

For RC-IWK reached the following agreement, such as:

[0011]

The base station provides for the UE a set of AP (e.g. by the other SSID, HESSID or BSSID identifier), when the interoperable use of these AP WLAN moving mechanism; i.e. UE can be moved to the base station transparently; base station based on measurement reports, for example, provided by the UE and UE moves across the control group;

[0012]

WLAN mobile set is a collection of one or more SSID / HESSID / BSSID's, UE belonging to the same WLAN AP between a mobile set for each base station is transparent to the mobile; i.e., does not notify the base station information on the mobile moves within the WLAN UE sets ;as well as

[0013]

All AP belong to the same WLAN mobile set of shared WLAN terminal (WT, WLAN Termination), the WT as a control plane (CP, Control Plane) and user plane (UP, User Plane) endpoint; and the UE at any point in time to connect up to a WLAN mobile set.

[0014]

RC-IWK and RA-IWK different places including, for example:

[0015]

(1) RC-IWK required tighter control network;

[0016]

(2) RC-IWK in the new TS command may also be as indicated by the network in connected mode, the UE that is in a connected state may receive specific threshold value and / or a new TS command, including whether downloaded to the WLAN information and the target WLAN Information;

[0017]

(3) In addition to the information of the target WLAN, the network may further include information indicating WLAN mobile set.

[0018]

[0059]

Step 101, upon receiving the base station to the user equipment context release indication sent by the MME, to determine whether the user equipment context release indication includes information indicating whether the user equipment to the service transferred from the LTE release cause WLAN information;

[0060]

Step 102, the base station includes an indication showing a case where the traffic is transferred from the WLAN to LTE release cause information, connection reconfiguration procedure initiated by the user equipment to the user equipment context release such that the user equipment is maintained at connected state.

[0061]

In the present embodiment, the RA-IWK process is different, the user context release indication device if the MME core network transmitted comprising "indicates the UE operations from LTE to WLAN" release cause information, even if the network detects that said UE in the LTE long MME indicating no traffic or release the RRC connection of the UE, the base station does not initiate the RRC connection release procedure may be initiated only RRC connection reconfiguration procedure such that the UE is maintained in a connected state.

[0062]

In the present embodiment, the user equipment context release indication may include a user equipment context release command message on the S1 interface (i.e. UE CONTEXT RELEASE COMMAND message), a release cause message may comprise the user equipment context release command message the increased traffic indication cause value transfer from LTE to the WLAN.

[0063]

For example, the UE CONTEXT RELEASE COMMAND message on the S1 interface in adding a new cause value (cause value), for example, "traffic offloading from LTE to WLAN". Moreover, adding new exception condition (abnormal condition): The base station determines the recording reservation RRC connection for the UE continues the service, no response message UE CONTEXT RELEASE COMPLETE.

[0064]

However, the present invention is not limited thereto, For example, the user equipment context release indication may be other messages, in addition release cause message may be other expressions like; specific embodiment can be determined according to the actual situation.
