Problems solved by technology

[0003] In the process of realizing the above-mentioned business transmission, the inventor found that at least the following problems exist in the prior art: once the PDN connection for routing SIPTO business is established, it can only route SIPTO business and cannot route core network business; Once the PDN connection of the network service is established, it can only route the core network service and cannot route the SIPTO service. Therefore, when a certain PDN connection is congested, the service corresponding to the PDN connection cannot be routed through this PDN connection, nor can it be routed through another PDN connection. Relatively idle PDN connection routes cannot reasonably allocate routing resources for UE services, resulting in low utilization of PDN connections, and cannot meet the operator's routing needs for UE services

Embodiment 1

[0028] An embodiment of the present invention provides a method for selecting a PDN connection for a UE service, such as figure 1 As shown, the method includes the following steps:

[0029] 101. The L-GW obtains the routing policy of the UE service.

[0030] 102. After obtaining the routing policy of the UE service, the L-GW selects a PDN connection for the UE service according to the routing policy.

[0031] Wherein, in this embodiment, the PDN connection of the SIPTO service may be selected to route the UE service or the PDN connection of the core network service may be selected to route the UE service.

[0032] 103. After the L-GW selects the PDN connection used for routing the UE service, the HNB routes the UE service through the PDN connection.

[0033] The method for selecting a PDN connection for a UE service provided by the embodiment of the present invention selects a PDN connection for a UE service according to a routing policy, and the PDN connection for routing a...

Embodiment 2

[0035] This embodiment provides a method for selecting a PDN connection for UE services. The embodiment of the present invention uses an example of obtaining a routing policy from an external routing policy network element, and selecting a PDN connection for UE service routing according to the routing policy to illustrate the route. Method of UE business. Such as figure 2 As shown, the method includes the following steps:

[0036] 201. The L-GW obtains the routing policy of the UE service from an external routing policy network element.

[0037] The routing policy network element may be a home base station management system (Home(e)NodeB Management System, HMS) or a policy and charging rules function (Policy and Charging Rules Function, PCRF). When the external routing strategy network element is HMS, L-GW can communicate with HMS through C1 interface to obtain routing strategy; when the external routing strategy network element is PCRF, L-GW can but not limited to through ...

Embodiment 3

[0053] This embodiment provides a method for selecting a PDN connection for a UE service. The embodiment of the present invention takes routing identification information obtained from a domain name system (Domain Name System, DNS) and selecting a PDN connection for a UE service according to the routing identification information as an example. The method for routing UE services is described. Such as image 3 As shown, the method includes the following steps:

[0054] 301. The UE requests the DNS to query the destination IP address to be accessed by the UE service.

[0055] 302. The DNS responds to the query request of the UE and returns the above destination IP address and routing identification information to the L-GW.

[0056] The routing identification information identifies the PDN connection used to route the UE service, for example, SIPTO represents the PDN connection for routing SIPTO service, and CN (Core Network, core network) represents the PDN connection for rout...

Abstract

An embodiment of the invention discloses a method and a device for selecting PDN (packet data network) connections for UE (user equipment) service, relates to the technical field of network communications and aims to relieve service pressure of congested PDN connections, increase utilization rate of idle PDN connections and reasonably distributes PDN connecting routing resources. The method includes acquiring a routing policy of the UE service; selecting PDN connections according to the routing policy; and routing the UE service by the selected PDN connections. The method and the device for selecting PDN connections for the UE service are mainly applied to the field of routing mobile phone terminal services.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and device for selecting a PDN connection for UE services. Background technique [0002] In modern network communications, a terminal equipment (User Equipment, UE) service is routed to a core network through an access network, and then routed to a public network through the core network. At present, in order to alleviate the network pressure of the core network, a local gateway (Local Gateway, L-GW) is configured in the access network, through which a home (e)NodeB (Home(e)NodeB, HNB) network is established. ) is directly routed to a packet data network (Packet Data Network, PDN) connection of the public network. The UE service is divided into core network service and selective IP offload service (Selected IP Traffic Offload, SIPTO) by the access point name (Access Point Name, APN), and the UE service identified as the core network service by the ...
