Embodiment 1

[0047] Embodiment 1: The process of accessing the communication system for users

[0048] This embodiment takes the LTE system as an example, and is also applicable to the UMTS system.

[0049] Step 201, RRC establishment process.

[0050] Step 202, the base station sends an initial UE message to the MME, and the message may carry new indication information, indicating that the MME needs to provide information required for user plane congestion.

[0051] Wherein, the information required for user plane congestion is UE subscription information and / or accessed service information. Subscription information of the UE, for example, whether the UE is a VIP user, or the VIP level of the user, etc. The service information that the user requests to access can be APN information, or further specific application service type information. For example, if the user requests to access the Internet service, the MME needs to know the specific Internet service type that the user accesses, su...

Embodiment 2

[0064] Embodiment 2, the base station obtains subscription information and / or access service information of the UE by using the newly defined S1 procedure. In this process, the base station requests UE-related subscription information or service information currently accessed by the UE from the MME according to the currently accessed UE.

specific Embodiment 2

[0065] The process of the specific embodiment two is as follows image 3 shown, including:

[0066] In step 301, the base station sends information related to the UE requesting access to the MME.

[0067] There may be multiple UEs connected to the base station, and the base station can send the list of connected UEs to the MME. The parameter of the UE can be eNB UE S1AP ID, or IMSI, TMSI, or other ID information that can identify the UE.

[0068] In step 302, the MME feeds back subscription information of the UE or service information accessed by the UE according to the received request and the UE list requested by the base station.

[0069] See step 202 for the specific description of UE's subscription information and access service information.

[0070] Wherein, when the MME feeds back the subscription information or the accessed service information of the UE, it may directly feed back the related information of all UEs included in the list. Or, further, the MME may also...

Abstract

The application discloses a method for solving the problem of congestion of a user plane. The method includes the following steps: a base station obtains subscription information of an access user and / or accessed service information from an MME, or, the MME can provide switching suggestions for the base station according to the subscription information of the access user and / or the accessed service information when the user plane is congested, and the base station performs switching or relocating according to the corresponding suggestions. By application of the method, a switching decision can be reasonably made, thereby effectively reducing the problem that a newly accessed network user cannot be accessed due to resource constraints.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for solving user plane congestion. Background technique [0002] Such as figure 1 As shown, now the 3GPP operator has put forward a new requirement to solve the problem of user plane congestion in the network. For example, when UE3 accesses cell A, air interface resources may be limited, and the network cannot allow UE3 to access. Or the direct bandwidth resources of the RAN and the EPC are limited, and it is impossible for new users to access the network to access services. In view of the above problems, operators hope to have an effective solution to reduce the occurrence of the above problems. Furthermore, when the above problems occur, the network can give priority to guaranteeing that subscribers with high levels can access the network or not affect the service experience of VIP users. [0003] There is currently no corresponding solution for the above requir...
