Description

Method and device for controlling message transmission

The invention belongs to the field of communication technology, and particularly relates to a message transmission control method and device.

In the 3GPP (the 3rd Generation Partnership Project) technology, during the service request process triggered by the UE (User Equipment), the service request process triggered by the UE in the CM-IDLE state is used To establish a secure connection between the UE and AMF (Access and Mobility Management Function, access and mobility management function). After this process, the UE can send uplink signaling messages, user data or reply to network paging requests. After receiving the service request message, AMF may perform an authentication process, and AMF should perform a security process. After establishing a secure signaling connection with AMF, the UE or the network can send signaling messages. For example, the UE sends a PDU (Protocol Data Unit) session establishment request to the network, or SMF (Session Management Function, session Management function) The user plane resource establishment process can be initiated through the PDU session requested by the AMF for the network or the PDU session in the service request message.

For any service request, the AMF can reply a service reply message to the UE to synchronize the PDU session status between the UE and the network. If the network cannot accept the service request, the AMF can reply a service rejection message to the UE. If the service request process is triggered by the UE sending user data, if the user plane resource establishment fails, the network may take further actions.

In the service request process triggered by the network, the network triggers the communication with the UE through this process, such as sending N1 signaling to the UE, called SMS (Short Message Service), and establishing a PDU session. Call user data. If the UE is in the CM-IDLE state or the CM-CONNECTED state, the network initiates the service request process triggered by the network. If the UE is in the CM-IDLE state and the asynchronous communication is not started, the network sends a paging request to (R)AN ((Radio) Access Network, (radio) access network)/UE. The paging request triggers the UE to initiate the service request process. If the UE starts asynchronous communication, the network suspends the service request process first, and then continues to perform the service request process when the UE enters the CM-CONNECTED state, that is, synchronizes the session context with the (R)AN and the UE.

For example, as long as the UE is in a connected state during 3GPP access, the network will access and page the UE through 3GPP, which requires the UE to always enable the function of monitoring paging, so there is a problem that the UE consumes a lot of power.

The second access network sends a control plane message; the UE receives the confirmation message from the network side.

Specifically, when the UE enters an idle state in the first access network, the UE sends a paging notification request message to the network side through the second access network; the UE receives the paging notification acknowledgement from the network side news.

Further, on the basis of the foregoing embodiment, if the control plane message is a paging notification message, the UE may also initiate a service request process through the first access network according to the paging notification message; or the control plane message is a connection release message , The UE locally releases the connection established through the first access network according to the connection release message.

Wherein, the control plane messages include but are not limited to paging notification messages and connection release messages.

When the UE accesses the first access network and the second access network, if the first access network is in the idle state and the second access network is in the connected state, the second access network can receive the network side The control plane message prevents the UE from monitoring the control plane message on the network side through the first access network all the time, and saves the power consumption of the UE.

Further, on the basis of the foregoing embodiment, the first access network is a 3GPP access network, and the second access network is a non-3GPP access network. The network side sends an N2 message to the N3IWF, and the N2 message carries control The N3IWF can send a control plane message to the UE; or the first access network is a non-3GPP access network, the second access network is a non-3GPP access network, and the network side sends an N2 message to the RAN. The N2 message carries a control plane message, so that the RAN sends a control plane message to the UE.

Further, on the basis of the foregoing embodiment, the network side may receive a request from the UE. The request is used to indicate that the UE supports receiving the control plane message through the second access network; and a response message is sent to the UE. The message is used to indicate that the network side receives the request.

Specifically, the network side receives the registration request of the UE, and carries prompt information or capability information in the registration request, and the prompt information or capability information is used to indicate that the UE supports receiving the control plane message through the second access network; The UE sends a registration acceptance message, and the registration acceptance message includes information used to indicate that the network side receives the registration request.

Specifically, when the UE enters an idle state in the first access network, the network side receives the receive paging notification request message sent by the UE through the second access network; sends a receive paging notification confirmation message to the UE .

Further, on the basis of the above-mentioned embodiment, the network side can also process the UE initiating a service request process through the first access network according to the control plane message; or notify the SMF to release the UE to set up through the first access network Connection.

When the UE is in the idle state in the first access network, if the state of the UE in the second access network changes from the connected state to the idle state, a paging notification is sent to the UE through the first access network news.

In the following method embodiments of the present invention, the first access network is a 3GPP access network and the second access network is a non-3GPP access network as an example for description.

In order to reduce the power consumption of the UE and save air interface resources, when the UE enters the idle state during 3GPP access, the UE can decide whether to turn off the function of monitoring paging according to its status in non-3GPP access.

Specifically, after the UE enters the idle state after 3GPP access, if the UE is in the idle state during non-3GPP access, the UE does not do any processing; after the UE enters the idle state during 3GPP access, if the UE enters the idle state during non-3GPP access, If it is in the connected state, the UE can turn off the function of monitoring paging. When the network side receives the UE's downlink data, if the UE is in the idle state during the 3GPP access and in the connected state during the non-3GPP access, the network sends a paging notification message to the UE through the non-3GPP access to indicate to the UE that it is 3GPP has received downlink data, and the message may carry information about the PDU (Protocol Data Unit) session (such as the ID of the PDU session) that received the downlink data. After that, the UE initiates a service request process, and the service request message may carry information about the PDU session. If the UE is in the idle state during 3GPP access, the state of the UE in non-3GPP access changes from the connected state to the idle state, and the UE reopens the function of monitoring paging.

In practical applications, the UE can determine whether to turn off the monitoring paging function in the following ways:

(1) The UE sends a request message to AMF to indicate whether the UE supports non-3GPP access Get the paging notification message on the receiving network side. AMF judges whether it can accept the UE's request based on the contract, operator's strategy or network capability. If the AMF can accept the UE's request, the AMF returns prompt information to the UE, indicating that it accepts the UE's request; if the AMF does not accept the UE's request, the AMF returns the reason for rejection to the UE.

(2) After the UE enters the IDLE state after the 3GPP access, the UE sends a request message for sending a paging notification via the non-3GPP access to the AMF through the non-3GPP access, and the AMF returns a confirmation message to the UE.

As shown in Figure 3, this embodiment describes the negotiation between the UE and the network whether to turn off the paging function during the registration process, including: step 301, the UE sends a registration request to the AMF, and the message carries prompt information or capability information, indicating The paging notification can be received through non-3GPP access; step 302, the AMF returns a registration acceptance message to the UE, and the message carries information about accepting/rejecting the UE's request.

As shown in Figure 4, this embodiment describes the negotiation between the UE and the network whether to close the paging function through non-3GPP access, including: step 401, the UE enters the idle state during the 3GPP access, and the non-3GPP access In the connected state, the UE sends a paging notification request message to the AMF; step 402, the AMF returns a paging notification message confirmation message to the UE.

As shown in Figure 5, the scenario described in this embodiment is that the UE enters the idle state during the 3GPP access. When the non-3GPP access is in the connected state, the UE has downlink data arriving in the 3GPP access, including: step 501, UPF (User Plane Function) receives the downlink data, but does not find the information of the access network node of the PDU session in the context of the UE, so the UPF sends a DDN (Downlink Data Notification) message to the SMF; Step 502: SMF sends N11 message to AMF, which carries N2 SM (N2 Session Management Information) information; Step 503, AMF finds that UE is in idle state within 3GPP access, AMF sends N2 message to N3IWF, and the message carries paging Notification message; step 504, the N3IWF sends a paging notification message to the UE; step 505, the N3IWF returns an N2 message confirmation to the AMF; step 506, the UE initiates a service request process.

In the embodiment of the present invention, after the UE enters the idle state in the 3GPP access, if the state of the UE in the non-3GPP access changes from the connected state to the idle state, then the UE opens the function of monitoring paging, and the AMF starts to connect through the 3GPP. Send a paging message to the UE.

As shown in Figure 6, it is a schematic diagram of the internal logic of the UE. As shown in Figure 7, this embodiment describes the interaction between 3GPP access to NAS (Non-access stratum) and non-3GPP access to NAS in the UE, which may include (A), (B), (C) and (D).

(1) The scenario for performing the process (A) is: the UE enters the idle state during non-3GPP access, but the 3GPP access NAS is not sure about the status of the UE in non-3GPP access, so it actively requests to obtain the status. The specific process is as follows.

Step 701, the 3GPP access NAS sends a status request message to the non-3GPP access NAS; step 702, the non-3GPP access NAS returns a status reply message to the 3GPP access NAS, and the message carries the status of the UE in the non-3GPP access.

(2) The scenario for performing process (B) is: the UE’s 3GPP access NAS subscribes to the non-3GPP access NAS to subscribe to the status of the UE in the non-3GPP access. When the UE status in the non-3GPP access changes, The non-3GPP-acquired NAS sends a notification message to the 3GPP-accepted NAS (that is, process (C)). The description of process (B) and process (C) is as follows: Process (B) is as follows: Step 703, 3GPP receiving NAS and sending status subscription message to non-3GPP receiving NAS; Step 704, Non-3GPP receiving NAS and receiving 3GPP receiving The NAS returns a status subscription reply message.

The process (C) is as follows: Step 705, the non-3GPP access NAS finds that the status of the UE in the non-3GPP access has changed, and sends a status notification message to the 3GPP access NAS. The message carries the status of the UE in the non-3GPP access.

(3) The scenario for performing process (D) is: the UE enters the connected state during 3GPP access, and there is no need to obtain the UE status of the UE in non-3GPP access. The UE cancels the subscription to obtain the related status. The description of process (D) is as follows: step 706, the 3GPP access NAS sends a status cancellation message to the non-3GPP access NAS; step 707, the non-3GPP access NAS sends a cancellation status subscription confirmation message to the 3GPP access NAS.

As shown in Figure 8, when the UE enters the idle state in the non-3GPP access network and the 3GPP access network is in the connected state, since the UE is in the idle state in the non-3GPP access network within a certain period of time, the AMF decides to delete the 3GPP accesses connections established within the network. The specific process is as follows: step 801, the AMF sends a delete connection request to the UE through the 3GPP access network, requesting the UE to delete the connection established in the non-3GPP access network, and the message may carry information about the connection to be deleted, such as an identifier; step 802. After the UE receives the connection deletion request, it locally deletes the connection established in the non-3GPP access network; step 803, the AMF deletes the connection established by the UE in the non-3GPP access network.

Specifically, the AMF sends a request message to the SMF, requesting the SMF to release the connection established by the UE through the first access network.

In the above embodiment, when the UE is in the connected state in the non-3GPP access network, if the UE enters the idle state in the 3GPP access network, the UE can turn off the paging monitoring function, thus reducing the power consumption of the UE. The network sends a NAS message to the UE through the non-3GPP access network to notify the UE of the arrival of the downlink data. There is no need to broadcast paging messages on the air interface, thereby reducing the overhead of air interface resources.

As shown in FIG. 9, the message transmission control apparatus of the embodiment of the present invention is applied to UE and includes: a receiving module 901, which is used when the UE enters the idle state in the first access network and is in the second access network. In the connected state, the control plane message of the network side is received through the second access network.

Specifically, the first sending module 902 is specifically configured to send a registration request to the network side, carrying prompt information or capability information in the registration request, and the prompt information or capability information is used to indicate that the UE supports the second The access network receives the control plane message; the receiving module 901 is specifically configured to receive a registration acceptance message from the network side, and the registration acceptance message includes information for indicating that the network side receives the registration request.
