Embodiment 1

[0038] With the development of virtualization technology, MME needs to adjust capacity more conveniently and dynamically. In order to better support multiple UE usage types, it is necessary to dynamically adjust the relative capacity of the MME according to the UE usage type, and notify the eNodeB of the adjusted relative capacity, so that the eNodeB can select an appropriate MME based on the latest relative capacity.

[0039] This embodiment provides a method, the MME can notify the eNodeB of the relative capacity corresponding to the usage type of the user equipment UE it serves.

[0040] Such as figure 2 As shown, the capacity notification method in this embodiment is applied to the MME, including:

[0041] Step 110, obtaining the relative capacity of the MME corresponding to the usage type of the user equipment UE it serves or the relative capacity corresponding to the MME group to which it belongs;

[0042] In this embodiment, the relative capacity of the MME correspon...

Embodiment 2

[0083] In this embodiment, the Mobility Management Entity (MME) notifies the eNodeB of the relative capacity corresponding to the MME group to which it belongs.

[0084] Such as Figure 4 As shown, the capacity notification method in this embodiment is applied to the MME, including:

[0085] Step 210, obtaining the relative capacity of the MME corresponding to the MME group to which it belongs;

[0086] In this embodiment, the UE usage type has a corresponding relationship with the MME group: in the MME pool, one UE usage type corresponds to one MME group, one MME group corresponds to one or more UE usage types, and one MME belongs to one or more UEs Usage type, one MME can belong to one or more UE groups, and can serve one or more UE usage types. The correspondence between the UE usage type and the MME group may be agreed between the MME and the eNodeB, or the MME may notify the eNodeB of the correspondence between the MME group and the UE usage type.

[0087] In this embo...

Embodiment 3

[0118] This embodiment provides a method for selecting a mobility management entity MME, which is applied to an evolved Node B, such as Figure 7 shown, including:

[0119] Step 210, obtaining the UE usage type of the access user equipment UE, which is recorded as the first UE usage type;

[0120] In this step, the eNodeB may acquire the UE usage type of the access UE from the message sent by the access UE; or, query the Home Subscriber Server HSS through the MME to acquire the UE usage type of the access UE. Wherein, the access UE refers to a UE requesting to access the eNodeB.

[0121] Step 220, determining the relative capacity of an optional MME corresponding to the usage type of the first UE;

[0122] In this embodiment, determining the relative capacity of the MME corresponding to the first UE usage type includes:

[0123] determining an MME serving the first UE usage type in the MME pool as an optional MME;

[0124] Finding the relative capacity of the MME correspon...

Abstract

The invention discloses a capacity notification, a MME selection method and a MME, and an evolved Node B (eNodeB). A MME acquires the relative capacity of the use type of user equipment (UE) to which the MME provides services or the relative capacity of a MME group to which the MME belongs, and notifies an eNodeB. The eNodeB acquires the UE type of an accessed UE and marks the UE type as a first UE use type. The relative capacity of a selectable MME corresponding to the first UE use type is determined. Based on the relative capacity of the selectable MME corresponding to the first UE use type, the MME is selected for the accessed UE. According to the application, for different UE use types or MME groups, the capacity notification enables the notification of different relative capacities to the eNodeB and can be applied to MME selection, is more flexible and can meet different requirements of capacities.

Description

technical field [0001] The present invention relates to the field of communication, in particular, to a capacity notification, a method for selecting an MME, an MME, and an evolved node B. Background technique [0002] The standardization working group of the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) is currently working on researching the packet switching core network (Packet Switch Core, referred to as PS Core) and the radio access network of the global system for mobile communication ( Universal MobileTelecommunication System Radio Access Network, referred to as the evolution of UTRAN). The research subject is called System Architecture Evolution (SAE for short), and the purpose is to enable the evolved packet network (Evolved Packet Core, EPC for short) to provide higher transmission rate, shorter transmission delay, optimized Grouping and supporting mobility management between Evolved UTRAN (Evolved UTRAN, E-UTRAN for ...
