Embodiment 1

[0121] Such as figure 1 It is a flowchart of a service distribution method between different networks disclosed in Embodiment 1 of the present invention. The method is applied to the ANDSF unit on the network side, and mainly includes the following steps:

[0122] Step S101, the ANDSF unit determines a preferred capability attribute to feed back to the UE according to a Network Capability Request sent by the UE, and the preferred capability attribute includes a non-seamless concurrent capability attribute or a seamless concurrent capability attribute;

[0123] In step S101, the network capability request sent by the UE is received by the ANDSF unit, capability negotiation is performed, and the result of the capability negotiation is fed back to the UE, so that the next step behavior of the UE is controlled by the network side, and the process of step S101 is executed In , when the determined preferred capability attribute is any one of the non-seamless non-capability attribute...

Embodiment 2

[0136] On the basis of the service distribution method between different networks disclosed in the first embodiment of the present invention, in figure 1 After step S104 is executed, Embodiment 2 of the present invention also discloses the process of updating the ISRP offloading strategy, as shown in figure 2 As shown, it mainly includes the following steps:

[0137] Step S105, the ANDSF unit initiates a multi-dimensional information subscription process, and obtains the subscribed multi-dimensional information;

[0138] In step S105, the multi-dimensional information includes information such as network load (load) status, traffic package / tariff, service quality, etc. During the subscription process of the ANDSF unit, any one of the above information can be subscribed, or multiple can be subscribed at the same time.

[0139] Among them, the subscription process of multi-dimensional information initiated by ANDSF unit includes:

[0140] The ANDSF unit initiates the subscrip...

Embodiment 3

[0153] On the basis of Embodiment 1 and Embodiment 2 of the present invention described above, after performing figure 1 In the step S101 shown, the embodiment of the present invention discloses that the UE side and the network side decide to execute the ISRP flow of offloading or the ISMP flow of network selection through capability negotiation. When the preferred capability attribute described in step S101 includes the non-seamless concurrent capability attribute or the seamless concurrent capability attribute, it is determined that the subsequent execution of the split ISRP process is performed, specifically as image 3 As shown, it mainly includes the following steps:

[0154] Step S201, the ANDSF unit receives a network capability request (Network Capability Request) sent by the UE, and the network capability request carries a set of capability attributes of the UE;

[0155] In step S201, the capability attributes in the capability attribute set of the UE include: seamle...

Abstract

The embodiment of the invention discloses a method and a device for shunting services among different networks. The method comprises the following steps: controlling user equipment (UE) to send an ISRP (Inter-system Mobility Policy) request to an ANDSF (Access Network Discovery and Selection Function) unit by a network side through the capability negotiation between the ANDSF unit and the user equipment; instructing to access a non-3GPP (3rd Generation Partnership Project) network by using a command for accessing the non-3GPP network generated according to the ISRP request by using the ANDSF unit; after the UE is connected with a 3GPP network and the non-3GPP network at the same time, instructing the user equipment which services are to reside in the 3GPP network and which services are to reside in the non-3GPP network according to an ISRP shunting strategy issued by the ANDSF unit according to the ISRP request. By means of the process above, services in the 3GPP network can be shunted by independently implementing the ISRP shunting strategy, so that the aim of saving network resources in a service shunting process by controlling the user equipment to initiate an ISRP flow by the network side through capability negotiation is fulfilled.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for distributing services between networks. Background technique [0002] With the wide application of smart terminals, in order to realize that UE (User Equipment, user equipment) resides in a 3GPP (3rd Generation Partnership Project, third generation partnership project) network and a non-3GPP network (for example, a WLAN network) at the same time, At present, it is implemented by modifying the corresponding operating system of the UE, so as to realize the distribution of services to the 3GPP network and the non-3GPP network (for example, WLAN network). [0003] In the prior art, the corresponding operating system of the UE is modified by means of OpenVSwitch, so that the OpenFlow function supported by it enables the terminal to reside in both 3GPP and non-3GPP networks (for example, a WLAN network), and then, the UE sends an ANDSF (Access Network Discovery and Se...
