Description
Technical Field
The present invention relates to a multi-connection technology of a communication system, and in particular, to a method and a system for resource control under multi-connection.
Background
The multimode terminal can enable seamless connectivity between heterogeneous radio access networks, such as cellular UMTS/EDGE/GPRS and IEEE 802.11 radio (WLAN). WLANs offer high data rates in small home and hot spot areas, while cellular networks offer greater flexibility and ubiquitous coverage, but at lower data rates, users would benefit from the benefits of both. In the coverage area of the WLAN access point, the multimode terminal uses the WLAN for data access and voip (voice over Internet protocol) application, and can also use the overlapping cellular network for voice call or media access.
With the development of network technology and the demands of users for services, a heterogeneous network will support the multi-connection capability of a multi-mode terminal, so that the terminal can communicate with multiple network connections simultaneously to carry one or more services. Different network connections have different characteristics and transmission capabilities, so that the requirement of multiple services and diversity of users can be better met.
The Multi-Connection control function (MCF) is responsible for maintaining the available Multi-Connection information of the Multi-Connection terminal and managing the transmission traffic of the terminal in different access networks. The MCF includes the following functional entities:
a Multi-connection Control-functional entity (MC-FE) is responsible for IP layer routing under multiple connections of a User Equipment (UE).
A Multi-connection Registration-function entity (MR-FE) is responsible for the management of the available connections of the UE and maintains the available connection information.
The MCF interacts with the Policy Storage-function Entity (PS-FE) or the Resource Admission Control Function (RACF) presence information. The PS-FE is responsible for storing the connection policy of the operator, such as bandwidth, cost, quality, security, etc.
And RACF is a standard for resource admission control established by the international telecommunication Union telecommunication standardization sector (ITU-T). In the latest RACF draft published by ITU-T, a Functional framework of RACF is provided, as shown in fig. 1, RACF is composed of two parts, which are a Policy Decision function Entity (PD-FE) and a Transport resource Control function Entity (TRC-FE), respectively, wherein TRC-FE interacts with a Transport function through an Rc interface, and interacts with a Transport resource execution function Entity (TRE-FE, Transport resource execution function) through an Rn interface; and the PD-FE interacts with the TRC-FE through an Rt interface, interacts with a user Premises Network (CPN) through an Rh interface, interacts with a Policy Enforcement function Entity (PE-FE) through an Rw interface, interacts with a Service Control Function (SCF) of a Service layer through an Rs interface, interacts with a Network Attachment Control Function (NACF) through an Ru interface, and interacts with other Next Generation Networks (NGNs) through Ri interfaces.
As shown in fig. 2, a resource control method under multiple connections in the prior art includes the following steps:
step 201: the UE detects a new available access network, attaches to the access network and acquires an IP address under the access network after access authentication;
step 202: the UE sends a connection update request message to the MCF, wherein the message contains new connection information, and the new connection information comprises: IP address under the new access network, etc.;
step 203: the MCF registers the new connection information and maintains the available connection information of the UE;
step 204: the MCF sends a resource request message to the PS-FE to perform QoS policy control on transmission resources in a new access network, wherein the resource request message carries new connection information;
step 205: after receiving the resource request message, the PS-FE carries out admission decision and makes a quality of service (QoS) strategy rule; PS-FE sends a resource request message to a transfer function entity (TF), wherein the message carries a QoS strategy rule formulated by the PS-FE;
step 206: after the TF installs the relevant QoS strategy rules, a resource request response message is sent to the PS-FE;
step 207: PS-FE sends a resource request response message to MCF;
step 208: the MCF sends a connection update request response message to the UE.
In step 205, because the MCF only provides new connection information for the PS-FE, the provided information is insufficient, so that the PS-FE cannot make an accurate QoS policy rule, and the PS-FE generally can only use the relevant QoS policy rule stored in advance locally, and cannot provide dynamic QoS policy control for the resource request from the MCF, so as not to achieve the purpose of controlling the transmission resource.

step 901: the UE detects a new available access network, attaches to the access network and acquires an IP address under the access network after access authentication;
step 902: UE sends a connection update request message to MCF, wherein the message contains new connection information, such as IP address under a new access network;
step 903: the MCF registers the new connection information and maintains the available connection information of the UE;
step 904: when the MCF determines that the new connection carries out reliability backup on all services borne by the UE under the old connection, the MCF carries corresponding information of new connection information, type four and type four in a resource request message sent to the RACF;
here, the corresponding information of type four is: old connection information.
Step 905: the RACF receives the resource request message, and acquires corresponding QoS information according to the application type information which is the corresponding information of type four and type four;
specifically, the RACF receives the resource request message, identifies that the current application type information is type four, and acquires QoS information (such as bandwidth, priority, etc.) of all services of the user loaded on the old connection according to the old connection information; here, the obtaining may be obtaining from a RACF corresponding to the old connection information.
Step 906: RACF makes admission decision of resource request message according to resource availability information of UE new access network, user subscription list and other information, if admission, then executes step 907; otherwise, ending the flow;
step 907: RACF formulates QoS strategy rules of corresponding transmission resources, and reserves resources;
specifically, the RACF formulates a QoS policy rule for all service transmission resources according to the obtained QoS information of all services of the user loaded on the old connection, resource availability information of the new access network, a user subscription list, and the like, and performs resource reservation.
Step 908: the RACF returns a resource request response message to the MCF;
step 909: the MCF returns a connection update request response message to the UE.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements, etc. that are within the spirit and principle of the present invention should be included in the present invention.
