Embodiment one

Referring to FIG. 2 , it is a schematic flowchart of a user equipment handover method provided in this embodiment. The method shown in FIG. 2 includes the following steps S201-S202:

S201: The cellular network source access device determines that the UE performs handover to the cellular network target access device.

S202: The cellular network source access device sends a handover request message to the cellular network target access device, and the handover request message includes the identifier of the UE in the non-cellular network; wherein, the identifier of the UE in the non-cellular network is used to indicate the cellular The network target access device performs multi-stream aggregation data transmission between the target logical function entity and the non-cellular network target access device and the UE.

Wherein, the UE accesses the cellular network and the non-cellular network at the same time, and before the cellular network access device switches, the cellular network source access device performs multi-flow communication with the UE via the source logic functional entity and the non-cellular network source access device. Aggregated data transmission: After the cellular network access device is handed over, the cellular network target access device performs multi-flow aggregated data transmission between the UE via the target logical functional entity and the non-cellular network target access device. Among them, the "source logical functional entity" and the "target logical functional entity" can be the same device or different devices; the "non-cellular network source access device" and "non-cellular network target access device" can be the same device , and also for different devices. In addition, the "source logical functional entity" and the "non-cellular network source" access device can be set up together or independently; the "target logical functional entity" and "non-cellular network target access device" can be set up together or independently set up. Moreover, before and after the handover of the cellular network access device, the data for multi-stream aggregation may be the same or different; correspondingly, before and after the handover of the cellular network access device, the bearers for multi-stream aggregation may be the same or different.

For example, the UE periodically or triggers reports the UE's cellular network measurement report to the cellular network source access device, and the cellular network source access device determines that the UE meets the handover condition according to the UE's cellular network measurement report , that is, it is considered that the UE needs to be handed over; then the cellular network source access device can select a cellular network target access device according to the cellular network measurement report of the UE, and send a handover request message to the cellular network target access device. Among them, "the UE's cellular network measurement report" refers to the measurement report obtained by the UE after measuring the signal quality and signal strength of the access device in the cellular network; handover conditions and how to determine that the UE satisfies the handover conditions according to the measurement report You can refer to the prior art.

The "identification of the UE in the non-cellular network" can be the MAC (Media Access Control, Media Access Control) address of the UE in the non-cellular network; it can also be the AID (Association Identity, Association ID, The combination of the association identification number (that is, the association identification) and the identification of the non-cellular network source access device. Wherein, when the non-cellular network is a WLAN, the identifier of the non-cellular network source access device may specifically be the identifier of the source AP, for example, the source APBSSID (Basic Service Set Identifier, basic service set identifier).

For example, the identification of the UE in the non-cellular network is used to instruct the cellular network target access device to perform multi-stream aggregation data transmission between the target logical functional entity and the non-cellular network target access device and the UE, including: During the process of establishing a GTP-U (GPRS Tunelling protocol-user plane, GPRS channel protocol-user plane GPRS) tunnel between the cellular network target access device and the target logical functional entity by the cellular network target access device, the cellular network target access device The access device sends the identification of the UE in the non-cellular network to the target logical functional entity, so that the target logical functional entity can identify the received data from the target access device of the cellular network according to the identification of the UE in the non-cellular network Whether the packet is a data packet of the UE; wherein, the GTP-U tunnel is used to transmit the data packet communicated between the target access device of the cellular network and the target logical functional entity. GPRS is the English abbreviation of General Packet Radio Service.

It should be noted that the handover request message may also include a list of bearers to be established, wherein the list of bearers to be established includes an identifier of a bearer to be established, so that the cellular network target access device establishes a bearer to be established for the UE, so as to communicate with The UEs communicate with each other. Among them, the list of bearers to be established is the list of bearers established by the cellular network source access device for the UE, and the bearers to be established include: the bearers that perform multi-flow aggregation between the cellular network source access device and the UE and those that do not perform multi-flow aggregation bearer. In addition, the bearer list to be established may include the identifier of each bearer to be established, and the information of Qos (Quality of Service, quality of service) and tunnel endpoint (tunnel endpoint) corresponding to each bearer to be established; wherein, the information of the tunnel endpoint Including TEID (Tunnel Endpoint Identifier, Tunnel Endpoint Identifier) and the first transport layer address (Transport Layer Address); the "tunnel end point" here is assigned by the target access device of the cellular network, and is used to indicate the location of data transmission in the uplink data transmission path destination.

In addition, it should be noted that the cellular network target access device determines the target logical functional entity and the non-cellular network target access device according to the handover request message, and conducts For the specific implementation process of multi-stream aggregation data transmission, please refer to the following.

For example, step S202 can be implemented as: the source eNB sends a handover request message to the target eNB; wherein, the handover request message includes the identity of the UE in the WLAN, which is used to indicate that the target eNB communicates with the UE via "target WT and target AP" Multi-flow aggregated data transmission is performed between UEs.

In the user equipment handover method provided in this embodiment, since the handover request message sent by the cellular network source access device to the cellular network target access device includes the identifier of the UE in the non-cellular network, the cellular network access device handover During the process, the target access device of the cellular network can recognize the identity of the UE in the non-cellular network, so that the data transmission of multi-stream aggregation can be realized during the handover process, and compared with the existing technology, the multi-stream aggregation service can be reduced. Interruption time or keep multi-stream aggregation services uninterrupted, thereby improving user experience. Wherein, the target access device of the cellular network can associate the identity of the UE in the cellular network with its identity in the non-cellular network, so that the target access device of the non-cellular network can recognize the identity of the UE in the non-cellular network, Of course, it can also be implemented in other ways during specific implementation.

It should be noted that, in the prior art, since the target eNB cannot obtain the identity of the UE in the WLAN during the handover process of the eNB, the target eNB cannot recognize the identity of the UE in the WLAN, thus causing the target eNB to transfer the identity of the UE to the WLAN. After the data packet is sent to the target WT, the target WT cannot identify which UE the data packet belongs to, so that the target eNB cannot perform multi-stream aggregation data transmission with the UE, that is, the process of multi-stream aggregation data transmission is interrupted, resulting in The multi-stream aggregation service is interrupted, which makes the user experience poor.

Optionally, as shown in FIG. 3, after step S202, the method may further include:

S203: The cellular network source access device receives the handover response message sent by the cellular network target access device.

Step B: The cellular network source access device sends a release request message to the source logical functional entity; wherein, the release request message includes a bearer list to be released, which is used to instruct the source logical functional entity to return the data to be released on the bearer to be released to The cellular network source access device; the data to be released refers to the data received by the source logical functional entity for multi-flow aggregation and not yet transmitted to the UE.

Step C: The cellular network source access device receives the data to be released returned by the source logical functional entity.

For example, "stop sending data to the UE" in step A may include: stop sending data that performs multi-flow aggregation to the UE through a non-cellular network source access device, and stop directly sending data that does not perform multi-flow aggregation to the UE aggregated data. The "bearer list to be released" can also include information about the tunnel end point, etc.; where the information about the tunnel end point includes TEID and transmission address, where the "tunnel end point" refers to the allocation of the target access device of the cellular network and is used to indicate uplink data transmission Destination of the data transfer in the path.

It should be noted that, during specific implementation, after receiving the handover response message, the cellular network source access device will send an RRC connection reconfiguration message to the UE to enable the UE to perform radio resource reconfiguration, measurement reconfiguration, mobile Other information such as sexual reconfiguration, UE-related information reconfiguration, etc.

In yet another optional implementation manner, the handover response message includes the identifier of the non-cellular network target access device. In this case, after step S203, the method may further include: the cellular network source access device sends to the UE the identification of the non-cellular network target access device or the identification list of the non-cellular network access device corresponding to the target logical functional entity , so that the UE accesses the non-cellular network target access device.

For example, the identification list of the non-cellular network access device corresponding to the target logical functional entity refers to a list composed of the identifications of the non-cellular network access device corresponding to the target logical functional entity; specifically, it may be: the APgroup corresponding to the target WT The list formed by the identifiers of the APs in , that is, the AP list corresponding to the target WT, where the AP list includes the identifiers of the target APs.

Network access device, as a non-cellular network target access device. It should be noted that in this case, the "non-cellular network target access device" selected by the UE and the "non-cellular network target access device" selected by the cellular network target access device may be the same or different; or the same as an example.

In specific implementation, when the non-cellular network source access device is the same as the non-cellular network target access device, or when the identification of the non-cellular network source access device and the non-cellular network target access device belong to the same non-cellular network The network access device identification list, that is, when the source logical functional entity is the same as the target logical functional entity, the handover response message may not include the identification of the non-cellular network target access device.

In addition, when the UE uses the masqueraded MAC address to access the non-cellular network target access device, after the UE successfully accesses the non-cellular network target access device, the method may further include: the UE sends the masqueraded MAC address to The target access device of the cellular network enables the target access device of the cellular network to identify the UE, so as to perform multi-stream aggregation data transmission between the target logical functional entity and the target access device of the non-cellular network and the UE.

For example, after receiving the handover request message, the target access device of the cellular network first determines the target access device of the non-cellular network; and then determines the target access device of the non-cellular network according to the corresponding relationship between the target access device of the The target logical functional entity corresponding to the network target access device. For example, after receiving the handover request message, the target eNB first determines the target AP; then, according to the correspondence between the AP and the WT, determines the WT corresponding to the target AP as the target WT.

It should be noted that the handover request message may also include a list of bearers to be established, where the list of bearers to be established includes identifiers of bearers to be established. In this case, the method may further include: establishing a bearer to be established by the cellular network target access device to communicate with the UE.

S403: The cellular network target access device establishes a GTP-U tunnel between the target logical functional entity and the non-cellular network target access device; wherein, the GTP-U tunnel is used to enable the cellular network target access device to pass through the target logical functional entity and the non-cellular network target access device. Multi-stream aggregation data transmission is performed between the non-cellular network target access device and the UE; wherein, the GTP-U tunnel between the target logical functional entity and the non-cellular network target access device is established on the cellular network target access device During the process, the target access device of the cellular network sends the identification of the UE in the non-cellular network to the target logical functional entity, so that the target logical functional entity can identify the received UE from the cellular network according to the identification of the UE in the non-cellular network Whether the data packet of the target access device is the data packet of the UE.

For example, step S403 may include: the target access device of the cellular network sends a tunnel establishment request message to the target access device of the non-cellular network; the target access device of the non-cellular network replies a tunnel establishment response message to the target access device of the cellular network. Wherein, the tunnel establishment request message includes the identifier of the UE in the non-cellular network. In addition, the tunnel establishment request message may also include: a bearer list for multi-flow aggregation between the cellular network target access device and the UE, and the list includes: a multi-flow aggregation bearer list between the cellular network target access device and the UE The identifier of the bearer, the Qos level corresponding to the bearer, the information of the tunnel end point, etc.

In the user equipment handover method provided in this embodiment, since the handover request message received by the target access device of the cellular network from the source access device of the cellular network includes the identifier of the UE in the non-cellular network, the handover request message of the access device of the cellular network During the process, the target access device of the cellular network can recognize the identity of the UE in the non-cellular network, so that the data transmission of multi-flow aggregation can be realized during the handover process. Compared with the existing technology, the multi-flow aggregation can be reduced. service interruption time or keep multi-stream aggregation services uninterrupted, thereby improving user experience. The specific analysis process can refer to the above, and will not be repeated here.

Optionally, after step S403, the method may further include: the cellular network target access device sending a handover response message to the cellular network source access device. Exemplarily, the handover response message may include: the identifier of the target logical functional entity or the identifier of the non-cellular network target access device; further optionally, it may also include: Bearer list for flow aggregation. The function of each piece of information included in the handover response message can be referred to above, and will not be repeated here.

In the first and second embodiments above, optionally, the handover request message may also include one or more of the following information:

1) The UE's non-cellular network measurement report; used to instruct the cellular network target access device to determine the non-cellular network target access device.

Among them, "UE's non-cellular network measurement report" refers to the measurement report obtained by the UE after measuring information such as signal quality and signal strength of non-cellular network access devices; it may specifically include but not limited to the following information: non-cellular network access devices , and the RSRP (Reference Signal Receiving Power, reference signal receiving power) and RSRQ (Reference Signal Receiving Quality, reference signal receiving quality) corresponding to the non-cellular network access device.

The cellular network target access device may select a non-cellular network access device with better signal quality as the non-cellular network target access device according to the non-cellular network measurement report of the UE.

2) The identification of the non-cellular network source access device; used to instruct the cellular network target access device to select the non-cellular network target access device.

The target access device of the cellular network may, on the basis of the method for determining the target access device of the non-cellular network provided by the prior art, give priority to the access device of the non-cellular network source as the target access device of the non-cellular network. In this way, in the process of switching the cellular network access device, the UE does not need to switch from the non-cellular network source access device to the non-cellular network target access device, thereby saving the interaction information between the UE and the non-cellular network access device. make.

3) A bearer list for multi-flow aggregation between the cellular network source access device and the UE; used to instruct the cellular network target access device to select a bearer for multi-flow aggregation.

The cellular network target access device may, on the basis of the method for determining the multi-flow aggregation bearer between the cellular network target access device and the UE provided in the prior art, give priority to the connection between the cellular network source access device and the UE. The bearer for performing multi-flow aggregation between them is used as the bearer for performing multi-flow aggregation between the cellular network target access device and the UE. In this way, the UE does not need to release the bearer during the process of switching the cellular network access device, thereby saving the signaling overhead between the UE and the cellular network source access device.

The "bearer list for multi-flow aggregation between the cellular network source access device and the UE" can be a separate list; it can also be combined in the list of bearers to be established, for example, adding one or more bearers to the list of bearers to be established The flag bit is used to mark whether the corresponding bearer to be established is a bearer for multi-flow convergence between the cellular network source access device and the UE.

It should be noted that any one or more pieces of information in this optional implementation manner may be sent to the cellular network target access device through a message independent of the handover request message.

It should be noted that, during specific implementation, the "identification of the UE in the non-cellular network" in any of the above embodiments may specifically be an IP (Internet Protocol, Internet Protocol) address of the UE in the non-cellular network. In this case, the difference between the user equipment handover method and the above is that a GTP-U tunnel does not need to be established between the target access device of the cellular network and the target access device of the non-cellular network.

The corresponding relationship between some terms in Embodiment one and two and some terms in Embodiment three is shown in Table 1:

Table 1

Referring to FIG. 5 , it is a schematic diagram of a signaling flow of a user equipment handover method provided in this embodiment. The method shown in FIG. 5 includes the following steps S501-S510:

S501: The source eNB sends a handover request message to the target eNB; wherein, the handover request message includes the following information: the identity of the UE in the WLAN, the ERAB list to be established, the WLAN measurement report of the UE, and the identity of the source AP; where the source ERAB list Include source LWA ERAB list.

Wherein, the ERAB list to be established is the source ERAB list, including the identification of the ERAB to be established.

S502: The target eNB establishes the ERAB to be established, and determines the identity of the target AP according to the WLAN measurement report of the UE and the identity of the source AP; further determines the target WT corresponding to the target AP; and determines the target LWAERAB list according to the source LWA ERAB list.

S503: Establish a GTP-U tunnel between the target eNB and the target WT.

For example, the target eNB sends a tunnel establishment request message to the target WT; the target WT replies a tunnel establishment response message to the target eNB. Wherein, the tunnel establishment request message includes information such as the address of the UE in the WLAN, the target LWA ERAB list, and the target LWA ERAB list includes: the identity of the target LWA ERAB, the information of the tunnel end point, and the like. The tunnel establishment response message includes the information of the tunnel end point. Wherein, the information of the tunnel endpoint is used to indicate the information of the destination endpoint in the uplink/downlink data transmission; the tunnel endpoint carried in the tunnel establishment request message is assigned by the target eNB, and the tunnel endpoint in the tunnel establishment response message is assigned by the target WT.

S504: The target eNB replies a handover response message to the source eNB; wherein, the handover response message includes the identity of the target AP, the identity of the target WT, and the target LWA ERAB list.

S505: The source eNB judges whether the target WT is the same as the source WT according to the identity of the target AP or the identity of the target WT.

If yes, execute S506; if not, execute S508.

For example, the source eNB can directly determine whether the target WT is the same as the source WT according to the identity of the target WT; it can also determine the target WT corresponding to the target AP according to the corresponding relationship between the AP and the WT, and then determine the target WT and the source WT Is it the same.

S506: The source eNB sends an RRC connection reconfiguration message to the UE; wherein, the RRC connection reconfiguration message includes an LWA command message, and the LWA command message includes a target LWA ERAB list.

S507: The UE performs reconfiguration according to the RRC connection reconfiguration message, including performing multi-stream aggregation reconfiguration according to the LWA command message, and sends an RRC connection reconfiguration complete message to the target eNB.

After executing S507, execute S510.

S508: The source eNB sends an RRC connection reconfiguration message to the UE; wherein, the RRC connection reconfiguration message includes an LWA command message, and the LWA command message includes a target LWA ERAB list and an AP list corresponding to the target WT.

S509: The UE performs reconfiguration according to the RRC connection reconfiguration message, including multi-stream aggregation reconfiguration according to the LWA command message; after the reconfiguration is completed, sends an RRC connection reconfiguration complete message to the target eNB; and according to the AP list corresponding to the target WT Independently select the target AP and access it; and send a message of access success/failure to the target eNB.

For example, if the UE accesses the target AP successfully, an access success message is sent to the target eNB; if the UE fails to access the target AP, an access failure message is sent to the target eNB.

S510: The target eNB performs multi-flow aggregation data transmission with the UE via the target WT and the target AP according to the UE's identity in the WLAN; wherein, the target eNB and the target WT transmit data packets through the above-mentioned GTP-U tunnel.

Optionally, as shown in FIG. 6, in any step after step S505 and before step S510, the method may also include the following steps 1)-4):

If the judgment result in S505 is "yes", execute step 1); if the judgment result in S505 is "no", execute step 2).

1) The source eNB takes the ERABs in the source LWA ERAB list that do not belong to the target LWA ERAB list as the ERABs to be released, and generates the ERAB list to be released according to the ERABs to be released.

After performing step 1), perform step 3).

Wherein, generating the ERAB list to be released by the source eNB according to the ERAB to be released may specifically include: the source eNB includes the identifier of the ERAB to be released, the information of the tunnel end point, etc. in a list as the ERAB list to be released.

2). The source eNB takes all ERABs in the source LWA ERAB list as ERABs to be released, and generates a list of ERABs to be released according to the ERABs to be released.

3), the source eNB sends a release request message to the source WT; wherein, the bearer release request message includes the ERAB list to be released, which is used to instruct the source WT to return the data to be released on the ERAB to be released in the ERAB list to be released to the source eNB .

For example, the "release request message" may specifically be a WT release request message.

4). The source WT returns the data to be released to the source eNB; the source eNB sends the data to be released to the target eNB.

It should be noted that, when the source eNB determines that there is no data to be released that needs to be returned, the method may not perform the above steps 1)-4).

In addition, it should be noted that since the ERABs belonging to both the source LWA ERAB list and the target LWA ERAB list can always perform multi-stream aggregation data transmission before and after switching eNBs, it can be guaranteed that the ERABs belonging to both the source LWA ERAB list and the target LWA ERAB list can be guaranteed. The multi-stream aggregation service on ERAB is not interrupted. In addition, even if there is no ERAB belonging to both the source LWA ERAB list and the target LWA ERAB list, that is to say, the data transmission process of multi-stream aggregation will be interrupted; In the process, the target eNB can realize the data transmission of multi-flow aggregation, so compared with the data transmission in which the target eNB can realize multi-flow aggregation after eNB switching in the prior art, it can reduce the interruption time of the multi-flow aggregation service .

Optionally, as shown in Figure 7, the above S509 can be replaced by the following steps 1-5:

Step 1: UE starts a timer when receiving the RRC connection reconfiguration request message.

Step 2: The UE performs reconfiguration according to the RRC connection reconfiguration request message, and accesses the target AP.

Step 3: The UE judges whether it successfully accesses the target AP within the preset time period starting from the start of the timer.

If yes, go to step 4; if not, go to step 5.

Step 4: The UE sends an RRC connection reconfiguration complete message to the target eNB, wherein the RRC connection reconfiguration complete message includes notification information that the UE successfully accesses the target AP.

Step 5: The UE sends an RRC connection reconfiguration complete message to the target eNB, wherein the RRC connection reconfiguration complete message includes notification information that the UE fails to access the target AP.

It should be noted that, in the above embodiments, the "notification information of successful access to the target AP" and "notification information of unsuccessful access to the target AP" are carried in the RRC connection reconfiguration message. Carried in a message independent of the RRC connection reconfiguration complete message. In this case, optionally, if the target eNB does not receive the "Notification Information of Unsuccessful Access to the Target AP" within a period of time after sending the RRC connection reconfiguration message to the UE, it considers that the UE has successfully accessed the target AP. AP.

In this optional implementation, "the UE sends notification information about successful/unsuccessful access to the target AP to the target eNB" is added, so that the target eNB can know whether the UE has successfully accessed the target AP. If the access is successful, then Start the data transmission of multi-stream aggregation, otherwise, stop the data transmission of multi-stream aggregation.
