Description

A mobility management method and terminal

technical field

The present invention relates to the field of communication technologies, and in particular, to a mobility management method and a terminal.

Background technique

LTE (Long-Term Evolution, long-term evolution) and WiFi (WIreless-Fidelity, wireless fidelity) aggregation (LWA) technology, refers to support UE (User Equipment, user equipment) to receive and send IP (Internet Protocol, At present, 3GPP supports a variety of LTE and WiFi aggregation data technologies, which are divided into LTE and WiFi aggregation technologies at the LTE core network and LTE and WiFi at the radio access network (RAN, Radio Access Network) level. WLAN (Wireless LAN, wireless local area network) aggregation technology. In the aggregation of LTE and WiFi technologies at the LTE core network, there are two network architectures: trusted access and untrusted access, which support WLAN connection to the core network PGW (packet data access) in a trusted or untrusted manner respectively. network PDN gateway), in the untrusted mode, the UE establishes a PDN connection with the core network through the WLAN and establishes a secure connection (IP security protocol-IPSec tunnel) with the core network to ensure data security. When the UE establishes a PDN connection with the core network through the WLAN, there is no need to establish a secure connection, and only an IP tunnel needs to be established. After the UE establishes a PDN connection through the WLAN, the PGW can receive and send the UE's IP data stream through WiFi. The PGW can simultaneously receive or send UE data through LTE and WiFi at the same time, or it can only receive and send UE data through LTE or WiFi, similar to Yes, the UE can also receive and send LTE core network data through the WLAN.

The RAN-level LTE and WLAN aggregation (LWA, LTE and WLAN Ran Level Aggregation) technology of 3GPP R13 can support the LTE base station to offload part of the traffic to the WLAN for transmission to the UE. In this technology, the LTE eNB (LTE base station) offloads part of the RAN traffic to the WLAN from the PDCP (Packet Data Convergence Protocol) layer, and sends the downlink RAN traffic to the terminal through the WLAN, or the terminal transmits the data from the PDCP layer to the terminal. The RAN traffic is offloaded to the WLAN, and the uplink RAN traffic is sent to the LTE eNB through the WLAN. The WLAN equipment used for traffic offloading has no interface with the core network, and does not require WLAN core network equipment. The eNB can manage the LTE and WLAN networks in a unified manner. For example, the terminals are uniformly authenticated by the LTE network, which simplifies the network management process and facilitates centralized control. , the technology can also easily support cell-level load balancing between WLAN and LTE. However, LWA technology has relatively high requirements for the upgrade of WLAN equipment. In the scenario where the base station and the WLAN equipment are not co-located, an Xw interface needs to be established between the base station and the WLAN aggregation device (WT, WLAN Termination). interface), as shown in Figure 1 (MME represents mobility management entity, SGW represents serving gateway, S1 represents the interface between base station and packet core network). Later, 3GPP introduced another RAN-level LTE and WLAN aggregation technology, using IPSec RAN-level LTE and WLAN aggregation (LWIP, LTE WLAN Radio Level Integration with IPsecTunnel) technology, which has no upgrade requirements for traditional WLAN equipment. As shown in Figure 2 (LWA Bearer means LWA bearer, Split LWA Bearer means split LWA bearer, Switched LWA Bearer means switched LWA bearer, UDP means User Data Packet Protocol, RLC means Radio Link Layer Control Protocol, MAC means Media Access control), in the LWIP technology, the eNB offloads the RAN traffic from the PDCP layer (IP layer) to the WLAN. After the UE establishes an association with the WLAN, an IPSec tunnel is established between the UE and the LTE eNB to transmit data offloaded from the RAN.

Based on the current LTE and WiFi aggregation architecture on top of the core network, aggregation of LTE network services and WiFi access requires LWA gateway devices and terminals to establish LTE and WiFi communication links respectively. The gateway device is located upstream of the LTE PGW and can be integrated into the PGW. middle. However, for the LWA network architecture, the existing technology cannot solve the problem of UE mobility management. In actual situations, the network may not provide LWA services immediately when the UE is powered on or attached to the LTE network. It may meet certain conditions or certain operators can provide LWA services to the UE. If the network does not support LTE and Wifi aggregation, it is initiated. The establishment of LWA service LTE and WiFi communication links will lead to the failure of the signaling process, which will bring unnecessary signaling overhead and delay in establishing communication links, reducing network performance.

The mobility management method provided by the implementation of the present invention will be further described below.

In view of the problems of the prior art, an embodiment of the present invention provides a mobility management method. The method mainly includes: a UE receives location information broadcast by an LTE base station or a wifi AP. The UE matches the location corresponding to the location information with a pre-stored available location range for the LTE and wifi aggregation service. If the location belongs to the above available location range, the establishment of a communication link for the LTE and wifi aggregation service is initiated.

The solutions provided by the embodiments of the present invention will be specifically described below.

Example 1

This plan includes:

(1) The UE receives the location information broadcast by the LTE base station or the wifi AP.

This solution is suitable for various LTE and wifi aggregation architectures. The first transmission link is established between the terminal device and the LWA gateway device through LTE, and the second transmission link is established through WLAN. The network device can pass the LTE network through the first transmission link. The user equipment data is sent to the terminal, and the user equipment data can also be sent to the terminal through WiFi, which realizes the aggregation of user data streams on the network side. As shown in Figure 4, in the aggregated LTE and wifi service architecture on the core network, the LWA gateway function is located upstream of the PGW function of the LTE core network, and the data of the UE is shunted from the LWA gateway device to the different transmission links of the UE, that is, through the LTE core network. The first transmission link of the network and the second transmission link via the wifi transmission network, in the specific implementation, the network equipment can be located in the PGW equipment, or can be located in the integrated small base station (the integrated small base station integrates the LTE core network function) ). As shown in Figure 5, in the aggregated LTE and wifi service architecture in the PGW, the LWA gateway function is located in the PGW, and the wifi transmission network is directly connected to the PGW through S2a, or connected to the PGW-known security gateway ePDG (evolved data packet gateway) through the s2b interface. , the data of the UE is offloaded from the PGW to different transmission links of the UE. As shown in Figure 6, in the aggregated LTE and wifi service architecture in the eNB, the LWA gateway function is located in the eNB, the wifi transmission network is connected to the eNB through the IP network or the Sw interface, and the UE data is offloaded from the eNB to different transmission links.

The UE that supports LWA aggregation can receive the cell location related information indicated in the LTE cell broadcast information through the LTE air interface, that is, the first location information, for example, the cell identifier (Closed Service Group Identifier CSG-ID or Evolved Unified Terrestrial Radio Access). Network E-UTRAN cell global identifier ECGI), network identifier (public land mobile network identifier PLMN-ID) or tracking location area (TAC), etc., the UE can read the AP location-related information broadcast in the wifi cell through the wifi wireless interface, That is, the second location information, such as the service set identifier SSID or the basic service set identifier BSSID.

Wherein, AC in FIG. 4 to FIG. 6 represents an access control device.

(2) The UE matches the location corresponding to the received location information with the pre-stored available location range for the LTE and wifi aggregation service.

The available location range of the LWA service is stored in the UE memory (such as a SIM card), and the available location range of the LWA service is the effective location range of the LTE link and the wifi link for establishing the LWA service. The available location range saved by the UE may be the location area related to LTE, that is, the effective range of the LWA service based on the location of the LTE network, such as the cell identity (CSG-ID/ECGI), network identity (PLMN-ID) or tracking location supported by the LWA service. A list of areas (TACs); it can also be a location area related to wifi, that is, the effective range of the LWA service based on the location of the Wifi network, such as a list of SSIDs or BSSIDs supported by the LWA service.

In particular, the available location range for the LTE and wifi aggregation service pre-stored by the UE may be downloaded and saved by the UE from the network server in advance. For example, if there is a server dedicated to providing the effective range of the LWA service, the server can be located in In the LTE core network, Wi-Fi transmission network or internet external network, the UE attaches to the LTE network or connects to the Wi-Fi transmission network and then accesses the server, and can download the effective range of the LWA service to the memory for storage.

The UE uses the location corresponding to the first location information or the second location information to match the effective service range of the LWA service.

(3) If the location corresponding to the location information belongs to the above-mentioned available location range, initiate the establishment of an LTE communication link and/or a wifi communication link for the LTE and wifi aggregation service (to send an establishment request to the network, and the network assigns a tunnel address to the terminal) ).

The range of locations where the LTE communication link and the wifi communication link are established may or may not be the same. According to the above, the UE can save the effective range of the LWA service based on the location of the LTE network or the location of the wifi network (ie, the above-mentioned available location range). There are the following situations:

When the UE initiates the establishment of the LTE communication link for LWA and the location range of the wifi communication link is the same: if the location information includes the first location information and does not include the second location information, if the first location (the first location The location corresponding to the location information) belongs to the effective range of the first LWA service based on the location of the LTE network, and initiates the establishment of an LTE communication link and a wifi communication link for the LTE and wifi aggregation service. Or, if the location information includes the second location information and does not include the first location information, if the second location (the location corresponding to the second location information) belongs to the valid range of the second LWA service based on the location of the wifi network , initiates the establishment of an LTE communication link and a wifi communication link for the LTE and wifi aggregation service. Or, if the location information includes the first location information and the first location information, if the first location belongs to the first LWA service valid range based on the LTE network location and the second location belongs to the first location based on the wifi network. 2. The effective range of the LWA service, initiates the establishment of the LTE communication link and the wifi communication link for the LTE and wifi aggregation service.

The conditions (location range) for the UE to initiate the establishment of the LTE communication link and wifi communication link for LWA are different:

If the location information includes the first location information and does not include the second location information, if the first location is within the effective range of the first LWA service based on the location of the LTE network, initiate the establishment of an LTE communication link for the LWA service; When the first location belongs to the effective range of the third LWA service based on the location of the LTE network, the establishment of the wifi communication link of the LWA service is initiated; or,

If the location information includes the second location information and does not include the first location information, and the second location is within the effective range of the second LWA service based on the location of the wifi network, the establishment of an LTE communication link for the LWA service is initiated, and the first When the second location belongs to the effective range of the fourth LWA service based on the location of the wifi network, the establishment of the wifi communication link of the LWA service is initiated; or,

If the location information includes the first location information and the first location information, the first location belongs to the effective range of the first LWA service based on the location of the LTE network, and the second location belongs to the second LWA service based on the location of the wifi network. When the effective range is in, initiate the establishment of the LTE communication link of the LWA service; when the first location belongs to the effective range of the third LWA service based on the location of the LTE network, and the second location belongs to the effective range of the fourth LWA service based on the location of the wifi network, initiate the LWA The service's wifi communication link is established.

In the implementation, in addition to the effective range of the LWA service as the condition for establishing the LWA transmission link, there may also be other further restrictions. (connecting) wifi initiates the establishment of a wifi transmission link.

In implementation, the LWA gateway and the terminal device respectively establish an LTE transmission link and a wifi transmission link through the LTE wireless access network and the WLAN. The LTE transmission link is defined by the first tunnel address of the LWA gateway and the first tunnel address of the terminal device; the wifi transmission link is defined by the second tunnel address of the LWA gateway and the second tunnel address of the terminal device. The first transmission link and the second transmission link are layer 3 tunnels and layer 2 tunnels. The first transmission link and the second transmission link can be different types of tunnels. For example, the first transmission link is a GPRS tunnel, and the second The transport link is a VxLAN (Virtual Local Area Network) tunnel. The network device allocates the first tunnel address and the second tunnel address to the terminal device respectively. Wherein, the first tunnel address is the IP layer address, link layer address or high layer protocol address of the terminal in the LTE network, and the second tunnel address may be the IP layer address, link layer address or high layer protocol address of the terminal in the WiFi network .

Wherein, the LWA gateway side addresses of the LTE transmission link and the wifi transmission link may be stored in the UE, that is, the first tunnel address and the second tunnel address of the LWA gateway side. When the UE enters the valid range of the LWA service, it needs to request the first tunnel address and the second tunnel address on the terminal side.

In a feasible implementation manner, when the terminal is attached to the LTE network, (a network device, which may be specifically a core network device) allocates a first tunnel address to the terminal through a NAS message.

The first tunnel address allocated by the network to the terminal is allocated by the network to the terminal through the NAS message: in the process of attaching the terminal to the LTE network, the PGW allocates the IP address in the LTE network to the terminal, and when the UE enters the establishment of the LWA service LTE transmission link (communication After the valid range of the link), the terminal sends an LTE transmission link establishment request to the network and uses the IP address in the LTE network as the first tunnel address. When the UE enters the valid range for establishing the wifi transmission link of the LWA service, the terminal sends a wifi transmission link establishment request to the network server, and the network server allocates the second tunnel address to the terminal. For example, the network server allocates the second tunnel address to the terminal after receiving the request for establishing a wifi transmission link sent by the terminal through WLAN or LTE.

The above network server is used to allocate the first tunnel address of the LTE transmission link and the second tunnel address of the wifi transmission link to the terminal. The network server address is stored in the terminal memory. In particular, for different location ranges, the terminal can store different The network server address, such as domain name address, IP address, etc.

As can be seen from the above, the solution of Example 1 can be shown in Figure 7, including:

Step 71a: the terminal reads the current location information such as the cell ID Cell ID, the tracking location area TAU or the network ID PLMN broadcasted by the LTE cell (eNB);

Step 71b: The terminal reads the current location information such as SSID or BSSID broadcasted by the wifi cell (AP);

Step 72: After performing steps 71a and/or 71b, determine whether to establish an LTE and/or wifi communication link according to the current location information;

Step 73: The UE requests the LTE and/or wifi link address from the server Server; then steps 74a and/or 74b are performed;

Step 74a: establish a wifi communication link between the UE and the LWA gateway;

Step 74b: An LTE communication link is established between the UE and the LWA gateway.

Example 2

This plan includes:

(1) The UE receives the location information broadcast by the LTE base station or the wifi AP.

The UE that supports LWA aggregation can receive the cell location related information indicated in the LTE cell broadcast information through the LTE air interface, that is, the first location information, for example, the cell identifier (Closed Service Group Identifier CSG-ID or Evolved Unified Terrestrial Radio Access). Network E-UTRAN cell global identifier ECGI), network identifier (public land mobile network identifier PLMN-ID) or tracking location area (TAC), etc., the UE can read the AP location-related information broadcast in the wifi cell through the wifi wireless interface, That is, the second location information, such as the service set identifier SSID or the basic service set identifier BSSID.

(2) The UE matches the location corresponding to the received location information with the pre-stored available location range for the LTE and wifi aggregation service.

The available location range of the LWA service is stored in the UE memory (such as a SIM card), and the available location range of the LWA service is the effective location range of the LTE link and the wifi link for establishing the LWA service. The available location range saved by the UE may be the location area related to LTE, that is, the effective range of the LWA service based on the location of the LTE network, such as the cell identity (CSG-ID/ECGI), network identity (PLMN-ID) or tracking location supported by the LWA service. A list of areas (TACs); it can also be a location area related to wifi, that is, the effective range of the LWA service based on the location of the Wifi network, such as a list of SSIDs or BSSIDs supported by the LWA service.

In particular, the available location range for the LTE and wifi aggregation service pre-stored by the UE may be downloaded and saved by the UE from the network server in advance. For example, it is assumed that there is a server dedicated to providing the effective range of the LWA service on the network side. The server can be located in In the LTE core network, Wi-Fi transmission network or internet external network, the UE attaches to the LTE network or connects to the Wi-Fi transmission network and then accesses the server, and can download the effective range of the LWA service to the memory for storage.

The UE uses the location corresponding to the first location information or the second location information to match the effective service range of the LWA service.

(3) If the location corresponding to the location information does not belong to the above-mentioned available location range, initiate the release of the LTE communication link and the wifi communication link for the LTE and wifi aggregation service (including sending a release request to the network, and the network releases the LWA service to the terminal) communication link).

The effective location range of the LWA service for releasing the LTE communication link and the wifi communication link may or may not be the same. According to the above, the UE can save the effective range of the LWA service based on the location of the LTE network or the location of the wifi network. There are the following situations:

When the release effective range (location range) of the LTE communication link and wifi communication link for LWA is the same: if the location information includes the first location information and does not include the second location information, if the first location information If it does not belong to the effective range of the first LWA service based on the location of the LTE network, the release of the LTE communication link and the wifi communication link for the LTE and wifi aggregation service is initiated. Or, if the location information includes the second location information and does not include the first location information, if the second location does not belong to the valid range of the second LWA service based on the location of the wifi network, initiate an aggregation service for LTE and wifi The LTE communication link and the wifi communication link are established and released. Or, if the location information includes the first location information and the first location information, if the first location does not belong to the valid range of the first LWA service based on the LTE network location and/or the second location does not belong to the wifi-based The second LWA service effective range of the network location initiates the release of the LTE communication link and the wifi communication link for the LTE and wifi aggregation service.

When the effective ranges of the LTE communication link and the wifi communication link for releasing the LWA service are different:

If the location information includes the first location information and does not include the second location information, if the first location does not belong to the effective range of the first LWA service based on the location of the LTE network, the LTE communication link that initiates the LWA service is released ; When the first location does not belong to the effective range of the third LWA service based on the LTE network location, the wifi communication link that initiates the LWA service is released; or,

If the location information includes the second location information and does not include the first location information, and the second location does not belong to the effective range of the second LWA service based on the location of the wifi network, the LTE communication link of the LWA service is initiated to release, When the second location does not belong to the effective range of the fourth LWA service based on the location of the wifi network, the wifi communication link that initiates the LWA service is released; or,

If the location information includes the first location information and the first location information, the first location does not belong to the effective range of the first LWA service based on the location of the LTE network, and/or the second location does not belong to the location-based wifi network. When the second LWA service is within the effective range, the LTE communication link that initiates the LWA service is released; the first location does not belong to the third LWA service valid range based on the LTE network location, and/or the second location does not belong to the fourth LWA service based on the wifi network location. When the LWA service is within the effective range, the wifi communication link that initiated the LWA service is released.

In the implementation, before the UE deletes the LTE transmission link and/or wifi transmission link of the LWA service when the LWA service is valid, if other specific conditions are met, the link release can also be triggered, for example, the UE initiates the release after detaching from the LTE network. For the LTE transmission link, when the UE moves out of the wifi coverage or disassociates (disconnects) from the wifi, it initiates the release of the wifi transmission link.

In implementation, the LWA gateway and the terminal device respectively establish an LTE transmission link and a wifi transmission link through the LTE wireless access network and the WLAN. The LTE transmission link is defined by the first tunnel address of the LWA gateway and the first tunnel address of the terminal device; the wifi transmission link is defined by the second tunnel address of the LWA gateway and the second tunnel address of the terminal device. The first transmission link and the second transmission link are layer 3 tunnels and layer 2 tunnels. The first transmission link and the second transmission link can be different types of tunnels. For example, the first transmission link is a GPRS tunnel, and the second The transport link is a VxLAN tunnel. The network device allocates the first tunnel address and the second tunnel address to the terminal device respectively. Wherein, the first tunnel address is the IP layer address, link layer address or high layer protocol address of the terminal in the LTE network, and the second tunnel address may be the IP layer address, link layer address or high layer protocol address of the terminal in the WiFi network .

Wherein, the LWA gateway side addresses of the LTE transmission link and the wifi transmission link may be stored in the UE, that is, the first tunnel address and the second tunnel address of the LWA gateway side. When the UE enters the valid range of the LWA service, it needs to request the first tunnel address and the second tunnel address on the terminal side. Therefore, when the UE moves out of the valid range of the LWA service, it only needs to initiate the release of the first tunnel address and the second tunnel address on the terminal side.

In a feasible implementation manner, before the terminal attaches to the LTE network, when the UE moves out of the effective range of the LWA serving LTE transmission link (communication link), the terminal sends an LTE transmission link release request to the network server and releases the LTE network The IP address in the LTE transmission link is used as the first tunnel address. Before the terminal leaves the coverage of the wifi network, when the UE moves out of the valid range of the LWA service wifi transmission link, the terminal sends a wifi transmission link release request to the network server to release the second tunnel address allocated to the terminal. For example, the network releases the second tunnel address allocated to the terminal after receiving the wifi transmission link release request sent by the terminal through WLAN or LTE.

The above network server is used to release the first tunnel address of the LTE transmission link and the second tunnel address of the wifi transmission link of the terminal. The network server address is stored in the terminal memory. In particular, for different location ranges, the terminal can store different The network server address, such as domain name address, IP address, etc.

It can be seen from the above that the embodiment of the present invention specifically provides a mobility management method for LWA: the UE determines whether it is located in the effective location range of the LWA service according to the location information broadcast by the LTE base station or the wifi AP, and when it is located in the effective location range of the LWA service.
