Detailed Description
In a multi-interface and multi-connection scenario, the LMA needs to control flow migration according to the real-time connection state (such as the activation and disconnection state of the interfaces) of the multi-interface of the terminal. When a new interface is connected to the network, the LMA transfers the existing service flow which is more suitable for the new interface to the new interface according to the real-time interface state; when an interface leaves the network (for example, disconnection), the LMA needs to transfer the traffic flow on the interface to the active available interface according to the state of the interface disconnection. In this case, the above operation procedure of the LMA needs to be based on the traffic policy, and the traffic policy needs to be synchronized with the terminal.
In a multi-interface and multi-connection scenario, when an MN is handed over between different access networks, in order to improve handover performance (e.g., reduce packet loss and handover delay during handover), a bidirectional tunnel needs to be established between the access device and the MN before and after handover for tunneling packets. In addition, some parameters need to be exchanged between the access devices before and after the handover to assist the completion of the fast and smooth handover process. Therefore, it is necessary to record multi-interface and multi-connection real-time location information, such as an Access Point (AP) ID, an access network element ID, and the like, on the server, so that the access devices obtain addresses of each other to complete information interaction for assisting handover.
In practical application, as shown in fig. 2, a multi-interface multi-access server may be deployed in a multi-interface multi-connection network, and the multi-interface multi-access server may be connected to an anchor point network element, an access point, an access device, and other access network elements, and may also be connected to a terminal such as an MN.
The terminal such as MN or the access network element may report the state information of the terminal (such as interface state information, location information, etc. of the terminal) to the multi-interface multi-access server. The anchor network element may obtain the above information from the multi-interface multi-access server to trigger a mobility management procedure (e.g., flow migration or performing fast handover, etc.) for the terminal.
And the access network elements such as the access point and the access equipment can report the load information of the access network to the multi-interface multi-access server. The anchor network element may obtain the above information from the multi-interface multi-access server to trigger a mobility management procedure (e.g., flow migration or performing fast handover, etc.) for the terminal.
In addition, the terminal can also obtain the service flow strategy information from the multi-interface multi-access server by sending a request so as to select the interface, or the service flow is migrated between different interfaces, or a proper access technology is selected for the service according to the service flow characteristics. Similarly, the anchor point network element may also obtain the service flow policy information from the multi-interface multi-access server, and perform better mobility management on the terminal accordingly.
In general, a multi-interface multi-access server may be deployed in a multi-interface multi-connection network, where the multi-interface multi-access server acquires location information of a terminal, interface state information, load information of an access network, and the like from the terminal and/or an access network element to trigger a mobility management procedure (e.g., stream migration or performing fast handover, etc.) for the terminal. And, the above information can also be synchronized to the anchor network element and the access network element.
When the interface state information reporting procedure shown in fig. 3 is performed, the interface state information reporting procedure of the MN may be initiated by the terminal or the access network element to update the interface state to the multi-interface multi-access server. The Access network element may be an Access point, such as a BS, an AP, an eNodeB, and the like, and an Access device, such as an Access Controller (AC), a Serving GateWay (S-GW), and the like.
In fig. 3, the update of the MN interface state information may be initiated by the terminal, as shown in steps 1 and 2. MN uses the connected interface to send interface state information update request to the multi-interface multi-access server.
For example, the MN owns two interfaces simultaneously: a cellular interface If1 and a WLAN interface If 2. The MN may use the current connection interface If1 to report interface status information, i.e. current interface information of interfaces If1 and If2, to the multi-interface multi-access server. The interface state information includes information such as MN _ ID (identification), access technology type, interface state (strong radio signal quality/poor radio signal quality/no connection), and interface ID.
And the multi-interface multi-access server creates or updates the state information of the current interface for the MN according to the information in the received interface state information updating request. The interface states include:
the quality of interface wireless signals is strong: when the interface signal strength is higher than a certain threshold value for a period of time, the air interface wireless quality is good.
The quality of the interface wireless signal is poor: when the interface signal strength is lower than a certain threshold value for a long time, the air interface wireless quality is poor and is not suitable for communication. At this time, the available interface should be used to send an interface status information update request to the multi-interface multi-access server.
The interface is not connected: without any signal strength. At this time, the connected interface is used to send an interface status information update request to the multi-interface multi-access server.
It should be noted that the above description is only a specific classification, and the interface states may be classified into suitable communication and unsuitable communication. The interface state in the actual application can be divided according to the actual application environment, the needs of the operator, and the like.
The update of the MN interface state information may also be initiated by the access network element, as shown in steps 3 and 4. If the access devices such as AC, S-GW, etc. know the state of the interface currently connected with the MN, the access devices can send an interface state information updating request to the multi-interface multi-access server, and the updating request contains information such as MN _ ID, access technology type, interface state, interface ID, etc.
The access point can learn the current interface state of the MN in the process of accessing the interface to the network, such as: the AP detects through a specific access technology and informs the access equipment of the MN interface state obtained through detection. The access point may be an Evolved Node B (eNodeB), a wlan AP, and the access device may be an AC, an S-GW, and the like.
The access point can learn the interface state of the MN through layer two detection or other mechanisms, such as: in some access technologies, after the access point forwards the message to the terminal, it will receive a two-layer acknowledgement message from the corresponding interface of the terminal. If the access point still does not receive the two-layer confirmation message from the terminal within a certain time after forwarding the message, the interface is considered to lose the connection.
The multi-interface multi-access server creates or updates the state information of the current interface for the MN according to the interface state information updating request sent by the access network.
The multi-interface multi-access server maintains the state information of the current interface of the MN.
As shown in steps 5, 6 and 7, after the current interface information of the MN is updated, the multi-interface multi-access server may respond to the interface state information request message of the anchor point network element and send the corresponding interface state information to the anchor point network element; or actively sending the updated interface state information to the anchor point network element.
Specifically, step 5: the anchor point network element actively requests the multi-interface multi-access server for the interface state information of the mobile node;
step 6: the multi-interface multi-access server responds to the mobile node interface state information requested by the anchor point network element;
and 7: in addition, the multi-interface multi-access server can also actively push the interface state information of the mobile node to the anchor point network element;
for example, the anchor point may make a flow migration decision based on the state information of the current interface. And the service flow on the interface without connection or with poor signal quality is migrated to the available connection interface, so that uninterrupted data flow is ensured, and the user experience is ensured.
When the location information reporting procedure shown in fig. 4 is performed, the location information of the MN may be composed of geographical location information and network location information corresponding to an MN interface. Wherein,
address location information: longitude and latitude;
network location information: an Access Network Identifier, a Public Land Mobile Network (PLMN) ID or a Service Set Identifier (SSID) or a Network Access Point (NAP) ID corresponding to the connection interface, and an ID or an IP address of the connected Access Network element.
The update of the MN location information may also be initiated by the terminal or an access network element (e.g., AC, S-GW, etc.) to update the MN location information on the multi-interface multi-access server.
The update of the MN location information may be initiated by the terminal as shown in steps 1, 2. The MN uses the connected interface to send an MN position information updating request to the multi-interface multi-access server.
For example, the MN has two interfaces at the same time, a cellular interface If1 and a WLAN interface If 2. The MN can report the location information of the MN's current connection interface, i.e., the location information of interface If1, to the multi-interface multi-access server using the current connection interface If 1.
And the multi-interface multi-access server creates or updates the position information of the current connection interface for the MN according to the information in the MN position information updating request.
The MN location information may also be initiated by the access network element, as shown in steps 3, 4. If the access devices such as AC, S-GW, etc. know the location information of the current connection interface of the MN, an MN location information updating request can be sent to the multi-interface multi-access server, and the updating request comprises MN _ ID, access technology type, interface ID, location information, etc.
The access device learns the MN location information through relevant approaches, such as: and acquiring the current geographical position information of the terminal through a specific mechanism of a related access network.
In the process of accessing the interface to the network, the network location information of the current connection interface can be obtained, such as: the access point informs the access equipment of the position information of the current connection interface of the MN.
And the multi-interface multi-access server creates or updates the MN position information for the MN according to the MN position information updating request of the current connection interface sent by the access network element.
The multi-interface multi-access server maintains MN location information.
As shown in steps 5, 6 and 7, after the current interface information of the MN is updated, the multi-interface multi-access server may respond to the interface location information request of the network element device such as the pre-switching/post-switching access network element, and send the corresponding interface location information to the relevant network element; or the updated interface position information can be actively sent to the network element equipment such as the access network element before switching or the access network element after switching.
Specifically, step 5: the access network element actively requests the multi-interface multi-access server for the interface position information of the mobile node;
step 6: the multi-interface multi-access server responds to the mobile node interface position information requested by the access network element;
and 7: in addition, the multi-interface and multi-access server can also actively push the interface position information of the mobile node to the access network element.
For example, the movement of the MN causes the MN to switch from the previous access network element to the new access network element (which may be a handover of the same access technology or a handover of a different access technology). The former access network element can obtain the IP address of the new access network element from the multi-interface multi-access server, and the new access network element can also obtain the IP address of the former access network element from the multi-interface multi-access server, so as to assist the completion of the rapid and smooth switching.
When the access network load information reporting procedure shown in fig. 5 is performed, the access network element may notify the multi-interface multi-access server of the access network load information, and the multi-interface multi-access server maintains the access network load information, where the load information may be created by using the access network element as an index. The notification of the network load may be reported directly by the access point or via the access device. The access device may be an S-GW, an AC, an Evolved packet data Gateway (ePDG), and the like.
In the steps 1 and 2, the access point directly informs the current network load condition of the access point; the multi-interface multi-access server creates or updates the current network load condition;
in steps 3 and 4, the access point reports the current access network load information of the access point to the access equipment, and after the access equipment receives the wireless network load information, the access equipment synthesizes the network load condition acquired by the access equipment and sends a network load notice to the multi-interface multi-access server; the multi-interface multi-access server creates or updates the current network load condition;
in steps 5 and 6, the anchor point network element actively requests the current access network load information from the multi-access multi-interface server;
in step 7, the multi-interface multi-access server actively informs the anchor point network element of the access network load information;
and the anchor point network element provides mobility management services such as rapid switching, flow migration and the like for a user according to the terminal interface state information, the terminal position information, the access network load information and the service flow strategy which are obtained from the multi-interface multi-access server.
When the service flow policy issuing process shown in fig. 6 is performed, the issuing of the service flow policy may include two processes: the terminal obtains the business flow strategy from the multi-interface multi-access server, and the anchor point network element obtains the business flow strategy from the multi-interface multi-access server.
Wherein, step 1 and step 2 describe a policy downloading procedure initiated by the terminal. The process can define new information independently and also continue to use the existing network access flow, and define new specific attributes in the existing information for requesting the service flow strategy;
specifically, step 1.1: the mobile node requests the service flow strategy and sends a service flow strategy request message to the access equipment. The service flow strategy request message comprises a user identifier;
step 1.2: after receiving the service flow strategy request message, the access device sends the service flow strategy request message to the multi-interface multi-access server;
step 2.1: after receiving the request message from the access device, the multi-interface multi-access server issues a service flow strategy related to the user to the access device according to the user identification carried in the message;
step 2.2: the access device issues the user service flow strategy to the MN.
In step 3, when the service flow strategy changes, the multi-interface multi-access server can also actively push the service flow strategy to the mobile terminal. For example, the server actively sends the service flow policy to the access device where the user is currently located, and the access device sends the received service flow policy to the MN;
in step 4 and step 5, the anchor point network element requests the service flow strategy of the user from the multi-interface multi-access server after the user is registered. The traffic policy at the anchor network element needs to be consistent with the traffic policy at the MN.
The MN can select a proper interface for various services according to the service flow strategy; the anchor network element may perform flow migration in a specific scenario according to the service flow policy.
It should be noted that: in the above embodiment, the multi-interface and multi-access server is a logical functional entity, and may be a separate network element entity or may be deployed on an existing network element entity according to an actual operation scheme. Moreover, the issuing of the service flow strategy can be that a multi-interface multi-access server actively pushes the service flow strategy to a terminal and an anchor point network element; or the terminal and the anchor point network element actively request the multi-interface multi-access server.
The service flow strategy comprises the following steps: and selecting a strategy of a corresponding access technology interface according to the service flow characteristics, adjusting a strategy of flow migration selection according to network congestion, and the like.
And, similar to the state information of the terminal, the access network load information also belongs to the state information; accordingly, the state information of the terminal and/or the network can be acquired by the multi-interface multi-access server.
As can be seen from the above description, the operation idea of the present invention for supporting multi-interface and multi-connection communication needs to first deploy a multi-interface and multi-access server in a multi-interface and multi-connection network, and then can execute the process shown in fig. 7, where the process includes the following steps:
step 710: and acquiring the state information of the terminal and/or the network by a multi-interface multi-access server deployed in the multi-interface multi-connection network, and distributing the service flow strategy to the terminal and the network.
Step 720: and according to the acquired state information, the multi-interface multi-access server assists a mobility management entity (such as an anchor point network element) to perform mobility management on the terminal.
In order to ensure that the above description and operation idea can be smoothly realized, an arrangement as shown in fig. 8 may be performed. Referring to fig. 8, fig. 8 is a system diagram for supporting multi-interface and multi-connection communication according to an embodiment of the present invention, where the system includes a connected state information obtaining unit and a mobility management unit, and both of the two units may be disposed in a multi-interface and multi-access server.
In practical application, the state information acquisition unit can acquire the state information of the terminal and/or the network and distribute the service flow strategy to the terminal and the network; the mobility management unit can assist a mobility management entity (such as an anchor network element) to perform mobility management on the terminal according to the state information acquired by the state information acquisition unit.
In summary, the present invention supports a multi-interface and multi-connection communication technology, which can ensure the synchronization of the service flow strategies of the terminal side and the network side, and effectively implement the mobility management for the terminal, regardless of the method or the system.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
