Technical field

The present invention relates to the device management techniques of the communications field, relate in particular to selection access network.

Background technology

Mobile terminal device is that whole mobile network runs the important component part in the service system; Open Mobile Alliance (Open Mobile Alliance; OMA) (Device Management DM) is meant through interactive mode administration order is issued on the terminal equipment from network side the equipment control in, and is carried out parameter configuration or carried out certain operation by terminal equipment; For example, multimedia message parameter configuration, software upgrade operation etc.

OMA DM normalized definition overall architecture, agreement and the communication mechanism of DM system, and the safety issue in the equipment control.The DM management tree of storing on the terminal can be considered to the interface that a DM server is managed the terminal through the DM agreement; Comprising some basic management object (Management Object; MO), the DM server reaches the purpose of control terminal resource through the operation to MO; Operational order is obtained (Get), replacement (Replace), execution (Exec), is duplicated (Copy), deletion (Delete) etc.

The overall structure of DM standard is as shown in Figure 1; As can be seen from Figure 1; Support the terminal of OMA DM business function that a DM client must be arranged; Be responsible for resolving the content of OMA DM agreement, and convert the operational order that the DM server issues to operational order that the terminal can be carried out, and carry out at the notice terminal.Simultaneously, the terminal also must comprise a management tree, and management tree is organized into tree with all available management objects in the terminal, and all here nodes all have unique unified resource sign, and (Unified Resource Identity URI) representes.As shown in Figure 2, be the structural representation of a management tree.

The associative operation order can be sent to the node of management tree through OMA DM agreement DM server,, management can be realized the terminal through operation to management tree such as Add, Copy, Delete etc.The node of management tree possibly comprise one group of environment configurations parameter in this terminal, dissimilar object, associative operation and some trigger mechanisms etc.

As shown in Figure 3, be the DM server that in the DM standard, defines bookkeeping steps flow chart sketch map to the terminal, this flow process mainly comprises:

Step 301: server is notified to the terminal transmit operation.

Step 302: after the terminal receives said operational notification, initiate initial session and connect, and report self identity information and facility information to server.

Step 303: server sends identity information and the operational order of self to the terminal.

Step 304: the operational order by the server transmission that receives is carried out at the terminal.

If session does not have suspended words, then step 303 and step 304 can repeat, and the terminal can receive and carry out more operational order, until session stop.

In the existing OMA DM standard, a series of connection management object is provided, and (Connectivity Management Object CMO) carries out the parameter configuration of different access networks (Network).For example; 3GPP circuit-switched network (Circuit-Switched Network; CS), 3GPP packet switching network (Packet-Switched Network; PS), 3GPP2 CDMA access metwork network (Code Division Multiple Access, CDMA), WLAN (Wireless Local Area Network, WLAN) etc.Continuous enhancing along with terminal capability; Often the multiple network environment can be supported in a terminal; Just produced the problem that network switches thus, conditions such as the type of service that signal strength signal intensity for example Network Based, user use, qos requirement, user present position are switched.
