Problems solved by technology

[0004] In practical applications, it may be necessary to change the user plane address of the S1 interface of the Serving GW. For example, the source Serving GW handles too many SAE bearers, which makes the source Serving GW overloaded, and some services processed on the source Serving GW need to be switched to On the target Serving GW, the user plane address of the S1 interface of the Serving GW is changed, and the existing relevant specifications do not provide a solution for how to let the eNB know the relevant information after the change, so the eNB fails to know the target Serving GW in time The user plane address of the S1 interface, which affects the normal development of the user UE
In addition, if the source Serving GW is overloaded for a long time, system performance will be affected, making it difficult to guarantee the service quality of user services

Embodiment 1

[0066] Based on the capabilities of the existing MME, the MME can detect the load of one or more service gateways managed by the MME. In the first embodiment, the MME detects that the load on a service The services of one or more UEs handled by the gateway are switched to another target serving gateway with a relatively light load.

[0067] In the first embodiment, it is assumed that the indication message is an improved SAE bearer modification request (SAE BearerModify Request) message. Wherein, the existing SAE bearer modification request message and the corresponding SAE bearer modification response message are used for the MME to notify the eNB to modify the QoS parameters of the specified SAE bearer.

[0068] see figure 2 , figure 2 It is a flow chart of obtaining the user plane address information of the S1 interface of the serving gateway in Embodiment 1 of the present invention, and the process may include the following steps:

[0069] Step 201: The MME selects a ...

Embodiment 2

[0088] In the second embodiment, it is assumed that a new transmission bearer update request message type is set in advance, such as an SAE bearer update request (SAE BEARER UPDATE REQUEST) message. The address information is sent to the eNB.

[0089] see image 3 , image 3 It is a flow chart of obtaining the user plane address information of the S1 interface of the serving gateway in Embodiment 2 of the present invention, and the process may include the following steps:

[0090] Step 301, the MME selects a UE that has established a service connection with the network side, and determines that the service of the UE needs to be switched from the source serving gateway to the target serving gateway, then the MME sends an SAE bearer update request message to the eNB corresponding to the UE, The message carries the user plane address information of the S1 interface of the target serving gateway.

[0091] Step 302: After receiving the SAE bearer update request message issued by...

Embodiment 3

[0102] see Figure 4 , Figure 4 is a schematic structural diagram of a mobility management entity in Embodiment 3 of the present invention, and the mobility management entity may include:

[0103] The first sending information processing unit sends an indication message to the eNB, where the indication message carries the user plane address information of the S1 interface of the target serving gateway that undertakes the service of the UE.

[0104] The aforementioned mobility management entities may further include:

[0105] The first receiving information processing unit receives a response message of the indication message sent by the eNB, where the response message carries the updated S1 interface user of the eNB allocated by the eNB for the S1 interface user plane transmission bearer belonging to the UE plane address information, and send the updated S1 interface user plane address information of the eNB to the target serving gateway.

[0106] The first received inform...

Abstract

The invention provides a method for acquiring user surface address information of an S1 interface of a serving gateway. The method mainly comprises the following steps that: a mobile management entity MME sends an indication message to an evolution base station eNB, and the indication message carries the user surface address information of the S1 interface of the objective serving gateway taking UE services of user equipment; and the eNB receives and analyzes the indication message to obtain the user surface address information of the S1 interface of the objective serving gateway. The invention also provides a mobile management entity and an evolution base station. The technical proposal provided by the invention provides a solving proposal for how the eNB acquires the user surface address information of the S1 interface of the serving gateway, thereby ensuring the normal expansion of user services.

Description

technical field [0001] The present invention relates to the technical field of communication of an evolved packet system, in particular to a method for acquiring user plane address information of an S1 interface of a serving gateway and a communication device. Background technique [0002] see figure 1 , figure 1 It is a schematic structural diagram of an S1 interface in an existing Evolved Packet System (EPS, Evolved Packet System). In the EPS, the interface between the access network and the core network is called the S1 interface. The S1 interface may include an S1 control plane interface (S1-C) mainly used for transmitting control signaling and an S1 user plane interface (S1-U) mainly used for transmitting user data. Specifically, such as figure 1 As shown, on a service connection of the UE, the relationship between the evolved base station (eNB) on the access network side that has a wireless connection with the UE and the mobility management entity (MME) on the core...
