[0093] This embodiment is the process of determining the anchor point for the user terminal to access the external network when the UE is attached to the network. As shown in FIG. 4 , the GTP protocol is used between the SAE Anchor and the 3GPP Anchor. In this embodiment, if UPE and 3GPP Anchor are integrated, then steps 11 and 13 are internal messages between UPE and 3GPP Anchor; if MME and UPE are integrated, then steps 9, 10, 14, and 16 are messages between MME and UPE internal news. The specific process is as follows:

[0094] 1. The UE discovers the network, establishes a connection, and sends an attach request message to the MME / UPE on the network side. The message may carry the UE's classmark or MRC(r) or MRCT(r), or the multi-radio access technology capability of the user terminal may be deduced Information;

[0095] 2. The MME / UPE requests user identity information from the UE;

[0115] This embodiment is the process of determining the anchor point for the user terminal to access the external network when the UE is attached to the network. As shown in FIG. 5 , the MIP protocol is used between the SAE Anchor and the 3GPP Anchor. In this embodiment, if UPE and 3GPP Anchor are integrated, then steps 11 and 13 are internal messages between UPE and 3GPP Anchor; if MME and UPE are integrated, then steps 9, 10, 14, and 16 are messages between MME and UPE internal news. The specific process is:

[0116] 1. The UE discovers the network, establishes a connection, and sends an attach request message to the MME / UPE on the network side. The message may carry the UE's classmark or MRC(r) or MRCT(r), or the multi-radio access technology capability of the user terminal may be deduced Information;

[0139] This embodiment is the process of determining the anchor point for the user terminal to access the external network when the UE is attached to the network. The UE supports local breakout. As shown in FIG. 6 , the MIP protocol is used between the SAE Anchor and the 3GPP Anchor. In this embodiment, if UPE and 3GPP Anchor are integrated, 11 and 13 are internal messages between UPE and 3GPP Anchor; if MME and UPE are integrated, then 9, 10, 14, and 16 are messages between MME and UPE inside information.

[0140] 1. The UE discovers the network, establishes a connection, and sends an attach request message to the MME on the network side. The message may carry the UE's classmark or MRC(r) or MRCT(r) or information that can deduce the user terminal's multi-radio access technology capabilities , if the UE stores HA or HoA information, carry it in the attach message;

Abstract

The utility model discloses a method, a unit and a system for ensuring a user terminal access an anchor point of an external network, wherein, a functional entity for information acquisition ensures the multi-access technical skill type of the user terminal according to the multi-access technical skill information of the user terminal, and sends the information with the multi-access technical skill type to 3GPP Anchor, 3GPP Anchor chooses a user terminal to access an anchor point of an external network according to the information with the multi-access technical skill type. The utility model has the advantages that enabling a proper anchor point to access an external network according to the multiple wireless access technical skill of a user terminal; for the user terminals which only support 3GPP access technology, business data is never processed by SAE Anchor and then routed to an external network, thus decreasing the number of processing nodes for users, reducing time delay, and synchronously mitigating the load of SAE Anchor.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and system for determining an anchor point for a user terminal to access an external network. Background technique [0002] In order to enhance the competitiveness of mobile networks, the 3rd Generation Partnership Project (3GPP) is studying a future network architecture, including System Architecture Evolution (SAE) and long-term evolution (Long-Term Evolution) of access networks. termevolution, LTE). The evolved access network is called E-UTRAN (Evolved UMTS Territorial Radio Access Network), and the evolved packet core network is called EPC (Evolved packetcore); the structure of EPC is shown in Figure 1, including Mobility Management Entity, MME), user plane entity (User Plane Entity, UPE), 3GPP Anchor and SAE Anchor four logical functional entities. MME is responsible for the mobility management of the control plane, including user equipm...
