Embodiment 1

[0036] An embodiment of the present invention provides a method for resource optimization under multiple PDN connections, such as figure 1 As shown, the method includes:

[0037] Step 101, acquiring type information of user equipment, said type information including at least one of service type and user type;

[0038] The service type includes local IP access LIPA service or core network CN service; the user type includes temporary user or permanent user.

[0039] The concept of CSG (Closed Subscriber Group, Closed Subscriber Group) is proposed in the home base station (HeNB[Home(e)NodeB family evolved base station] or HNB[HomeNodeB family base station]), CSG identifies a user group that allows access to Access-restricted cells (cells where the CSG is located) in one or more PLMNs (Publicland mobile network, public land mobile network). The cell where the CSG is located broadcasts a specific CSGID (identity), and only members belonging to the CSGID can access the cell. Curre...

Embodiment 2

[0056] An embodiment of the present invention provides a device for resource optimization under multiple PDN connections, such as figure 2 As shown, the apparatus may be an MME, and the apparatus includes: an acquisition unit 201 , a QoS optimization unit 202 , and a processing unit 203 .

[0057] An obtaining unit 201, configured to obtain type information of user equipment, where the type information includes at least one of a service type and a user type;

[0058] The service type includes local IP access LIPA service or core network CN service; the user type includes temporary user or permanent user.

[0059] After obtaining the type information of the UE, send an initial context setup request message to the base station, the initial context setup request message including the type information; in the solution provided by the embodiment of the present invention, the initial context setup request message is initialcontextsetuprequest;

[0060] Here, the base station may b...

Embodiment 3

[0069] It should be noted that the solution provided in this embodiment is a flow of resource optimization under multiple PDN connections mainly performed on the MME side. For the integrity of the solution, the solution provided by the embodiment of the present invention includes the Attach process of the user equipment UE and the PDN connection establishment process, wherein the Attach process of the UE and the PDN connection establishment process are not necessarily performed in the same base station, that is, the Attach process of the UE It is performed in base station A, and the PDN connection establishment process may be performed in base station B, but the Attach process of the UE may also include the PDN connection establishment process.

[0070] If the Attach process is performed in another cell, and the cell and the base station are under the same MME, this will not affect the MME's record of the service type and user type of the UE. When the UE moves, it will be updat...

Abstract

The invention discloses a resource optimization method and a device under multiple public data network (PDN) connections, relates to the technical field of communication network, and can solve the problem of unreasonable using of wireless resource when the wireless resource is insufficient. According to the scheme of the resource optimization method and the device under the multiple PDN connection, by obtaining the type information of a user device, when the information of the failure of the building of an initial background sent by a base station is received, a quality of service (QoS) adjusting mode is adopted to carry out resource optimization according to the type information. Or, the type information of the user device is obtained, when the number of the resources needed in building bearing is bigger than the number of surplus resources, the resource optimization is carried out according to preset mode according to the type information, wherein the number of the surplus resources is the number of current surplus resources of a base station reported to a mobility management entity (MME) by the base station when the base station detects that resource using condition exceeds a preset threshold value. Or, the base station receives the building request information of the initial background sent by the MME. When the base station is insufficient in resource, the information of the failure of the building of the initial background is sent to the MME, and the MME is indicated to change over the bearing and then rebuild the bearing. Or, the base station receives the building request information of the initial background sent by the MME, when the base station is insufficient in resource, the bearing is built according to a preset strategy and by using reserved resources, and the problem of unreasonable using of wireless resource can be solved. The method and the device are suitable to be adopted to carry out resource optimization under multiple PDN connections.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method and device for resource optimization under multiple PDN connections. Background technique [0002] 3GPP (3rdGeneration Partnership Project, the third generation partnership project) proposed the concept of H(e)NB[Home(e)NodeB, home base station] on the basis of (e)NB[(e)NodeB, base station]. )NB is a small base station that can be installed indoors and can be configured flexibly. It is mainly used in home and business environments. [0003] A type of LIPA (LocalIPAccess, local IP access) service is included in the requirements of H(e)NB. LIPA refers to the UE with IP capability accessing other IP capabilities of the same home / enterprise IP network through H(e)NB In the device, the service flow data of the LIPA service is directly accessed from the H(e)NB without passing through the operator's core network. Compared with the operator's core network...
