Description

 Message transmission control method and device  

The invention belongs to the field of communication technologies, and in particular relates to a message transmission control method and device.

In the 3GPP (3rd Generation Partnership Project) technology, in the service request process triggered by the UE (User Equipment), the UE in the CM-IDLE state triggers the service request process. Establish a secure connection between the UE and the AMF (Access and Mobility Management Function). After the process, the UE may send an uplink signaling message, a user profile or a paging request to reply to the network. After receiving the service request message, the AMF may perform the authentication process and the AMF shall perform the security process. After establishing a secure signaling connection with the AMF, the UE or the network may send a signaling message, for example, the UE sends a PDU (Protocol Data Unit) session establishment request to the network, or a SMF (Session Management Function, session) The management function can initiate a user plane resource establishment process through the AMF for the PDU session requested by the network or the PDU session in the service request message.

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

During the network-triggered service request process, the network triggers communication with the UE through the process, for example, sending N1 signaling to the UE, called SMS (Short Message Service), and establishing a PDU session user plane resource transmission. Call the user profile. If the UE is in the CM-IDLE state or the CM-CONNECTED state, the network initiates a network triggered service request procedure. If the UE is in the CM-IDLE state and the asynchronous communication is not initiated, the network sends a paging request to the (R)AN ((Radio) Access Network, (the wireless) access network)/UE. The paging request triggers the UE to initiate a service request procedure. If the UE initiates the asynchronous communication, the network first suspends the service request process, and when the UE enters the CM-CONNECTED state, the service request process is continued, that is, the session context is synchronized with the (R) AN and the UE.

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

The control plane message includes, but is not limited to, a paging notification message and a connection release message.

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 through the second access network. The control plane message is avoided, so that the UE keeps listening to the control plane message of the network side through the first access network, which saves the power consumption of the UE.

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

Further, on the basis of the foregoing embodiment, the network side may receive, when the UE enters an idle state in the first access network, a request message sent by the UE through the second access network, where the request message is used. It indicates that the UE requests the network side to send a control plane message through the second access network; and sends an acknowledgement message to the UE.

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

Further, on the basis of the foregoing embodiment, the network side may further process that the UE initiates a service request process by using the first access network according to the control plane message; or notify the SMF to release the UE to establish through the first access network. Connection.

During the idle state of the UE in the first access network, if the state of the UE in the second access network enters an idle state from the connected state, the first access network sends a paging notification to the UE. Message.

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.

In order to reduce the power consumption of the UE and save the air interface resources, after the UE enters the idle state after the 3GPP accesses, the UE may decide whether to disable the function of monitoring the paging according to the state in the non-3GPP access.

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

In an actual application, the UE may determine whether to disable the paging function by:

(1) The UE sends a request message to the AMF to indicate whether the UE supports receiving the paging notification message on the receiving network side through the non-3GPP. The AMF determines whether the UE's request can be accepted based on the contract, operator policy or network capability. If the AMF can accept the UE's request, the AMF returns a prompt message to the UE indicating that the UE's request is accepted; if the AMF does not accept the UE's request, the AMF returns a rejection reason to the UE.

(2) After the UE accesses the IDLE state in the 3GPP, the UE sends a request message for sending a paging notification through the non-3GPP access through the non-3GPP-oriented AMF, and the AMF returns an acknowledgement message to the UE.

As shown in FIG. 3, this embodiment describes whether the paging function is negotiated between the UE and the network during the registration process, including: Step 301: The UE sends a registration request to the AMF, where the message carries prompt information or capability information, indicating The paging notification may be received by the non-3GPP access; in step 302, the AMF returns a registration accept message to the UE, where the message carries the information of the request to accept/reject the UE.

As shown in FIG. 4, this embodiment describes whether the paging function is closed between the UE and the network through non-3GPP access negotiation, including: Step 401: The UE enters an idle state in the 3GPP access, and is accessed in the non-3GPP. The UE is in the connected state, and the UE sends a Paging Notification Request message to the AMF. In step 402, the AMF returns a Paging Notification message confirmation message to the UE.

As shown in FIG. 5, the scenario described in this embodiment is that the UE enters an idle state in the 3GPP access, and when the non-3GPP access is in the connected state, the UE has downlink data arrival 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: The SMF sends an N11 message to the AMF, where the message carries N2 SM (N2 Session Management Information) information. Step 503: The AMF finds that the UE is in an idle state in the 3GPP access, and the AMF sends an N2 message to the N3IWF, where the message carries the paging. The notification message is sent; in step 504, the N3IWF sends a paging notification message to the UE; in step 505, the N3IWF returns an N2 message confirmation to the AMF; and in step 506, the UE initiates a service request procedure.

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, the UE turns on the function of monitoring the paging, and the AMF starts to access through the 3GPP. The oriented UE sends a paging message.

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

(1) The scenario of the execution process (A) is as follows: the UE enters the idle state in the non-3GPP access, but the 3GPP accesses the NAS to determine that the UE is in the non-3GPP access state, and therefore actively requests to acquire the state, and the specific process is as follows.

Step 701: The 3GPP accesses the NAS to receive the NAS transmission status request message to the non-3GPP. In step 702, the non-3GPP accesses the NAS to receive the NAS return status reply message to the 3GPP, where the message carries the status of the UE in the non-3GPP access.

(2) The scenario of the execution process (B) is: the state in which the UE's 3GPP accesses the NAS to the non-3GPP to access the NAS subscription UE in the non-3GPP access state, when the state of the UE in the non-3GPP access changes, The NAS that is not accessed by the 3GPP sends a notification message to the NAS accessed by the 3GPP (ie, process (C)). The description of the process (B) and the process (C) is as follows: the process (B) is as follows: Step 703: The 3GPP accesses the NAS to receive the NAS to send the status subscription message to the non-3GPP; and in step 704, the non-3GPP accesses the NAS to the 3GPP. The NAS returns a status subscription reply message.

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

(3) The scenario of the execution process (D) is that the UE enters the connection state in the 3GPP access, and does not need to acquire the UE state of the UE in the non-3GPP access. The UE cancels the subscription to obtain the relevant status. The description of the process (D) is as follows: Step 706: The 3GPP accesses the NAS to send a cancel status subscription message to the non-3GPP access NAS; Step 707: The non-3GPP access NAS contacts the 3GPP to return the NAS to cancel the status subscription confirmation message.

As shown in FIG. 8, when the UE enters the idle state in the non-3GPP access network, and the 3GPP access network is in the connected state, the AMF decides to delete the UE in the non-3GPP access network in the idle state. The 3GPP accesses the 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 the information of the connection to be deleted, such as the identifier; 802. After receiving the delete connection request, the UE locally deletes the connection established in the non-3GPP access network. In 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 foregoing 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 may turn off the paging monitoring function, thereby reducing the power consumption of the UE. The network sends a NAS message to the UE through the non-3GPP access network, and notifies the UE of the arrival of the downlink data, and does not need to broadcast the paging message on the air interface, thereby reducing the overhead of the air interface resource.
