The technical solutions in the present application are clearly and completely described in the following with reference to the drawings in the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

When UMTS (Universal Mobile Telecommunications System) / LTE (Long Term Evolution) and WLAN (Wireless Local Area Networks) coexist, in UMTS/LTE, the base station equipment (Node B of UMTS or Within the coverage of the LTE eNB, there are multiple WLAN APs (Access Points), and the coverage of the AP is relatively small compared to the base station equipment.

Under the above network architecture, UMTS/LTE can use WLAN for offloading, and the corresponding shunting modes include seamless shunting and slotted shunting; seamless shunting means that there is a WLAN between 3GPP CN (Core Network) After the connection, the service is still connected to the 3GPP CN. Seated shunting means that there is no connection between the WLAN and the 3GPP CN, and the services are directly connected to the Internet after the traffic is offloaded.

The handover in the UMTS/LTE refers to a process in which the UE is handed over from one cell to another. The specific air interface process includes: (1) the base station device sends a handover command to the UE; (2) after the UE receives the handover command, disconnects the source cell. The connection is initiated to the target cell indicated in the handover command. (3) After the UE successfully accesses the target cell, the UE sends a handover success message to the target base station device, and the handover process ends.

The handover in the WLAN refers to a process in which the UE is handed over from one AP to another. The specific air interface process includes: (1) the UE discovers a new AP, and determines that the AP needs to be switched according to its own algorithm; (2) the UE and the current AP are associated; 3) After the UE establishes an association with the new AP, and the association is successfully established, the AP handover process ends. In addition, the handover of the UMTS/LTE and the WLAN refers to a process in which the UE is handed over from a UMTS/LTE cell to a WLAN AP. The specific air interface process includes: (1) the base station device learns that the UE has passed the measurement report or the geographical location information of the UE. Approaching a WLAN AP; (2) When the base station device decides to switch the UE to the WLAN, the RRC (Radio Resource Control) connection reconfiguration procedure is used to notify the UE to switch to the WLAN, and the RRC connection reconfiguration message is The identification information of the target AP (such as the frequency set and the SSID (Service Set Identifier), etc.) is included; (3) After the UE receives the RRC connection reconfiguration message, the AS (Access Stratum) layer is connected. The NAS (Non-Access Stratum) layer needs to be switched to the WLAN. At this time, the NAS layer of the UE triggers the WLAN module of the UE to find the corresponding access point for association (access); (4) After the AP successfully completes the association, The UE may establish a corresponding PDN (Packet Data Network) connection (seamless offload) or access the Internet (sewn split) through the WLAN; the AS layer of the UE sends an RRC connection reconfiguration to the base station device. Into the message, the base station apparatus notifies the corresponding bearer handover has been completed.

An embodiment of the present application provides a context information management method in a heterogeneous network, where the method is applied to an application scenario in which a 3GPP network to a non-3GPP network handover is required. The 3GPP network may be UMTS or LTE, and the non-3GPP The network can be WLANo

As shown in FIG. 1 , in an application scenario of performing a 3GPP network to a non-3GPP network handover, the context information management method in the heterogeneous network may include the following steps:

Step 101: The base station device obtains context information of the UE in the non-3GPP network.

The base station device is a base station device in a 3GPP network, such as an eNB (Evolved Node).

In the embodiment of the present application, the base station device obtains the context information of the UE in the non-3GPP network, including but not limited to: the base station device determines that the UE switches from the 3GPP network to the non-3GPP. In the network, context information of the UE in the non-3GPP network is obtained.

In the embodiment of the present application, the manner in which the base station device obtains the context information of the UE in the non-3GPP network includes, but is not limited to, the following manner: The base station device determines that the UE initially accesses from the non-3GPP network, and accesses in the subsequent process. In the case of the base station device, the base station device receives the context information of the current UE reported by the UE to the local base station device in the non-3GPP network; or the base station device receives the UE reported by the UE when the context information in the non-3GPP network changes, in the non-3GPP network. Context information; or, the base station device receives the context information of the UE that is reported by the UE after the UE is handed over to the target base station device in the non-3GPP network; or the base station device sends a message requesting to report the context information in the non-3GPP network to the UE, And receiving context information of the UE reported by the UE after receiving the message in the non-3GPP network.

Step 102: The base station device maintains context information of the UE in the non-3GPP network.

In the embodiment of the present application, the base station device maintains the context information of the UE in the non-3GPP network, including but not limited to: when the service of the UE is handed over from the base station device to the non-3GPP network, the base station device receives the core network and releases the UE in the 3GPP network. The information carried by the EPS (Evolved Packet System) of the service, and when the core network releases the EPS bearer of the UE in the 3GPP network, the base station device retains the context information of the UE in the non-3GPP network, that is, the base station device The context information of the UE in the non-3GPP network is not deleted.

Specifically, when the service of the UE is originally in the base station device, the service of the UE is transferred to the non-3GPP network due to the handover, etc., and the service of the UE is in the corresponding EPS bearer in the base station device, and the core network is switched in the UE. After completion, the base station device is required to release the EPS bearer of the UE in the 3GPP network. On this basis, in the embodiment of the present application, when the core network releases the EPS bearer of the UE in the 3GPP network, the base station device needs to retain the context information of the UE in the non-3GPP network, that is, the base station device does not delete the UE in the non-3GPP network. Context information in .

Step 103: The base station device determines, by using context information of the UE in the non-3GPP network, Whether to perform measurement configuration and/or whether to perform service switching; and/or, when determining that the UE switches from the base station device to other base station devices, transmit the context information of the UE in the non-3GPP network to other base station devices.

In the embodiment of the present application, based on the context information of the UE maintained by the base station device in the non-3GPP network, the base station device may use the context information of the UE in the non-3GPP network to determine whether to perform measurement configuration and/or whether to perform service switching; and/ Or, the base station device may send the context information of the UE in the non-3GPP network to the other base station when determining that the UE switches from the local base station device (in this case, as the source base station) to the other base station device (in this case, as the target base station) device.

In the embodiment of the present application, when the non-3GPP network is specifically a WLAN, the context information of the UE in the non-3GPP network includes the context information (ie, the WLAN context) of the UE in the WLAN.

In the embodiment of the present application, the context information of the UE in the WLAN includes at least: whether the UE currently has a service transmission in the WLAN; further, when the UE currently has a service transmission in the WLAN, the context information of the UE in the WLAN may further include However, it is not limited to one or any combination of the following: the corresponding service information, the mapping relationship between the service bearer (such as DRB (Data Radio Bearer)) information and the WLAN service on the 3GPP network side.

Further, the service information of the UE in the WLAN includes but is not limited to one or any combination of the following: the service identifier, the number of services, and the QoS Class of Service (QoS) level of the UE in the WLAN. Indicate) level, etc.

As shown in FIG. 2, in the application scenario of the 3GPP network to the non-3GPP network switching, the context information management method in the heterogeneous network may include the following steps:

Step 201: The UE obtains context information of the UE in the non-3GPP network.

The UE needs to maintain the context information of the specific UE in the non-3GPP network, The context information of the UE in the non-3GPP network can be directly obtained when needed.

Step 202: The UE sends the context information of the UE in the non-3GPP network to the base station device, where the base station device maintains the context information of the UE in the non-3GPP network, and the base station device determines whether to perform the context information of the UE in the non-3GPP network. Measuring configuration and/or whether to perform service switching; and/or, when determining that the UE switches from the base station device (as the source base station) to the other base station device (as the target base station), transmitting context information of the UE in the non-3GPP network to Other base station equipment.

In this embodiment, the UE sends the context information of the UE in the non-3GPP network to the base station device, including but not limited to: when the UE initially accesses from the non-3GPP network, and accesses the base station device in a subsequent process, the current The context information of the UE in the non-3GPP network is sent to the base station device; or the context information of the changed UE in the non-3GPP network (including the initial access base station device) when the UE changes the context information in the non-3GPP network. When the UE has a service in the non-3GPP network, the UE sends the context information of the current UE in the non-3GPP network to the base station device; or, the UE receives the context information from the non-3GPP network after receiving the handover to the target base station device; After the request of the base station device reports the message of the context information in the non-3GPP network, the context information of the current UE in the non-3GPP network is sent to the base station device.

In the embodiment of the present application, the foregoing base station device is a base station device (such as an eNB or an RNC) in a 3GPP network, and the 3GPP network is specifically UMTS or LTE; the non-3GPP network may be specifically a WLAN, and when the non-3GPP network is specifically a WLAN The context information of the UE in the non-3GPP network includes the context information (ie, WLAN context) of the UE in the WLAN.

In the embodiment of the present application, the context information of the UE in the WLAN includes at least: whether the UE currently has a service transmission in the WLAN; further, when the UE currently has a service transmission in the WLAN, the context information of the UE in the WLAN may further include But not limited to the following One or any combination: Corresponding service information, mapping of service bearers (such as DRB) information on the 3GPP network side and WLAN services. The service information of the UE in the WLAN includes but is not limited to one or any combination of the following: the service identifier, the number of services, the QCI level, and the like of the service of the UE in the WLAN.

In summary, in the embodiment of the present application, when the UE switches from the 3GPP network to the non-3GPP network, the base station device maintains the context information of the UE in the non-3GPP network, so that the base station device can utilize the context of the UE in the non-3GPP network. The information is processed in a related manner (for example, the base station device determines whether to perform measurement configuration and/or whether to perform service switching, etc. by using context information of the UE in the non-3GPP network), so as to solve how the UE is used in the non-3GPP network during the handover process. The problem of contextual information and can make the system work properly.

The embodiments of the present application are further described below in conjunction with specific network scenarios.

In this embodiment, the base station device uses the WLAN context (that is, the context information of the UE in the WLAN) to perform measurement configuration and service switching. The specific network scenario is shown in FIG. 3, and the base station device may be an RN of the UMTS or an LTE. eNB, the access point is an AP of the WLAN.

In this application scenario, the UE is only connected to the base station device, and three services are transmitted, and are respectively carried on DRB1, DRB 2, and DRB3. As the UE moves to the coverage of the access point 1, the base station device decides to switch the service 1 (the bearer on the DRB1) to the WLAN for transmission, and sends a bearer handover command to the UE. After receiving the command, the UE switches the service 1 to the access point 1, and further stores the correspondence between the service 1 and the DRB1. After the UE successfully completes the handover of the service 1, the core network sends a command to the base station device to release the EPS bearer corresponding to the service 1 of the UE. After receiving the command, the base station device releases the resource corresponding to the bearer, but still saves the current UE. The WLAN context, that is, the service 1 of the UE is in the WLAN, and further, the corresponding bearer before the service handover is DRB 1. Since the base station device knows that the UE currently has a service in the WLAN, the base station device configures the measurement of the WLAN (such as the measurement of the channel quality or the load information) for the UE. The measurement event configured in this embodiment is “the channel quality of the WLAN is lower than Threshold". In the subsequent process, the UE needs to monitor the WLAN according to the measurement configuration information. When the UE moves outside the coverage of the access point 1 and the WLAN channel quality measured by the UE is lower than the threshold configured by the base station, the UE is triggered. The measurement is reported, that is, the information is reported to the base station device. After receiving the measurement report, the base station device combines the current WLAN context information of the UE (the service 1 of the UE is in the WLAN), and the base station device sends a bearer handover command to the UE to switch the service 1 from the WLAN back to the base station device. Further, the base station device may further configure the DRB1 for the UE to transmit the service 1.

In summary, the base station device implements a reasonable measurement configuration and handover decision by preserving the WLAN context of the UE, ensuring the continuity of the UE service and ensuring the user experience.

In this embodiment, the base station device uses the WLAN context (that is, the context information of the UE in the WLAN) to perform the WLAN context transmission in the handover process. The specific network scenario is shown in FIG. 4, and the base station device may be the UMTS RNC or the LTE. The eNB, the access point is the AP of the WLAN.

The UE is initially within the coverage of base station device 1 and access point 1 while maintaining a connection with base station device 1 and access point 1. The UE has three services, the service 1 is transmitted on the base station device 1, and the service 2 and the service 3 are transmitted on the WLAN. Further, the base station device 1 and the UE need to retain the WLAN context information of the UE, that is, the service 2 and the service 3 Transmission on WLAN.

As the UE moves, the UE enters the coverage of the base station device 2 from the coverage of the base station device 1, and the base station device 1 switches from the base station device 1 to the base station device 2 based on the decision UE, and then the base station device 1 moves to the base station device 2 Sending a handover request message, and in the handover request message, the base station device 1 carries the current WLAN context of the UE (service 2 and industry) Traffic 3 is transmitted over the WLAN, and the 3GPP service context of the UE (Service 1 is transmitted at the base station device 1).

After receiving the handover request message, the base station device 2 carries the information for switching the service 1 to the base station device 2 in the handover command, and the base station device 1 transparently transmits the handover command to the UE. After receiving the handover command, the UE switches the service 1 to the base station device 2 based on the information carried in the handover of the service 1 to the base station device 2, and still keeps the service 2 and the service 3 transmitted at the AP.

If the base station device 1 does not transmit the WLAN context of the UE to the target base station device (ie, the base station device 2) during the handover process, or after the base station device 1 sends the handover command, the WLAN context of the UE changes (for example, the service 2 ends), Then, after the UE successfully accesses the target base station device (ie, the base station device 2), it also needs to notify the base station device 2 of its current WLAN context.

After the UE successfully switches to the base station device 2, the processing manners of the subsequent base station device 2 and the UE are the same as those in the embodiment shown in FIG. 3, and the subsequent related processes are not repeatedly described in this embodiment.

In this embodiment, the UE reports the current WLAN context (that is, the context information of the UE in the WLAN). The specific network scenario may be as shown in FIG. 3, and the base station device may be an RN of the UMTS or an eNB of the LTE. The point is the WLAN AP.

The UE first establishes a connection on the WLAN and transmits Service 1 and Service 2 on the WLAN. The subsequent UE establishes a connection with the base station device 1 and transmits the service 3. After the UE establishes a connection with the base station device 1, the UE actively reports the current WLAN context to the base station device 1 through the RRC dedicated signaling. After receiving the current WLAN context of the UE, the base station device 1 needs to save the WLAN context. Alternatively, the base station device 1 sends an RRC dedicated signaling requesting the WLAN context to the UE, and after receiving the RRC dedicated signaling, the UE reports the related information (ie, the current WLAN context), and the base station device 1 receives the current UE. WLAN After the context, you need to save the WLAN context.

The WLAN context may include whether there is a WLAN service (for example, lbit indicates whether there is a WLAN service). Further, when there is a WLAN service, the WLAN context may further include specific service information, where the service information may include the number of services and services. Logo, QCI, etc.

After the WLAN context is received by the base station device 1, the processing manners of the subsequent base station device 1 and the UE are the same as those in the embodiment shown in FIG. 3, and the subsequent related processes are not repeatedly described in this embodiment.
