Description

 Configuration negotiation method and device

 The present application claims priority to Chinese Patent Application No. 200710123670.2, entitled "Method and Apparatus for Configuring Negotiation," filed on September 28, 2007, the entire contents of which are incorporated herein by reference. .

Technical field

 The present invention relates to the field of communications, and in particular, to a method and apparatus for configuration negotiation.

Background technique

 In the Code Division Multiple Access High Rate Packet Data (CDMAHRPD) system, each service capability is embodied in the form of a protocol. Under the same protocol, different sub-protocol types are supported. Different features. For example: The default sub-protocol under the broadcast multicast protocol does not provide broadcast multicast function, the universal sub-protocol provides broadcast multicast function; the default security layer sub-protocol does not provide security layer function, and the common security layer sub-protocol provides security layer. Features.

 Because the Access Network (AN) is not aware of the protocol types supported by the Access Terminal (AT), it needs to be determined through configuration negotiation to determine whether service adjustment is required.

 An existing configuration negotiation process is as follows:

 Step 11: The AT reports the type of protocol it supports.

 Step 12: After receiving the supported protocol type reported by the AT, the AN takes the intersection according to the situation supported by the AN and the situation supported by the AT, and obtains a protocol type that can be recognized by both the AN and the AT in the session.

 The AN and AT save the final negotiation result in the session. When switching between ANs, session information can be transmitted through the AN interface (A13, A16, etc.), and the final negotiation result is transmitted from the source AN to the target AN. Since the target AN does not know all the protocol types supported by the AT, in addition, the protocol type configuration of the target AN and the source AN may be different, so the target AN cannot accurately determine whether renegotiation is needed to further adjust the services of the AN and the AT.

The current practice is that after the inter-AN switchover, that is, after the source AN switches to the target AN, the target AN does not know all the protocol types supported by the AT, so a reconfiguration negotiation is initiated, and the AT re-reports the supported protocol types. Then judge whether to make subsequent business adjustments. This reconfiguration The quotient is likely to be a useless negotiation, thus reducing the performance of the switch.

For example, the broadcast multicast support of AT, source AN, and target AN is as follows:

 The specific process is as follows:

 Step 21: Since AT does not support broadcast multicast, the result of negotiation with the source AN is that broadcast multicast is not supported.

 Step 22: In the case of switching between ANs, the target AN receives the session negotiation result delivered by the source AN, and the negotiation result does not support broadcast multicast.

 Step 23: The target AN does not know all the protocol types supported by the AT and re-initiates the configuration negotiation. Step 24: The target AN knows that the AT does not support broadcast multicast, and ends this invalid negotiation. Summary of the invention

 In view of this, the embodiments of the present invention provide a method and an apparatus for configuration negotiation, which can improve handover performance when switching between two access networks.

detailed description

 The present invention will be further described with reference to the drawings and specific embodiments, but the invention is not limited to the embodiments below.

 The embodiment of the present invention provides a method for configuration negotiation. Referring to FIG. 1, the method includes: Step 101: The source access network receives all protocol type information supported by the terminal reported by the terminal;

 Step 102: The source access network sends all protocol type information supported by the terminal to the target access network.

 Step 103: The target access network receives all the protocol type information supported by the terminal sent by the source access network, and determines whether a reconfiguration negotiation needs to be initiated.

 When the terminal switches between the source access network and the target access network, the source access network passes the A13 interface (corresponding to the switching scenario of dormant state switching) or the A16 interface (corresponding to the switching of the connection state switching) Scenario: Send all the protocol type information supported by the AT to the target AN. The target AN then determines whether to initiate reconfiguration negotiation according to the protocol type supported by the AT.

 The following takes the case of the Dormant state switching as an example:

An embodiment of the present invention provides a method for configuration negotiation. Referring to FIG. 2, the method includes: Step 201: The AT performs initial configuration negotiation with the source AN1, and all the protocols supported by the AT are supported by the AT. Type information.

 The AT performs the initial configuration negotiation when the source AN1 is connected, and sends a configuration request (ConfigurationRequest) message to the source AN1, where the configuration request message carries an AT supported protocol type (ATSupportedProtocols) attribute, and the AT is reported in the form of an AT support protocol type attribute. All protocol type information supported by AT. The AT support protocol type attribute is defined as follows:

 Step 202: The source AN1 saves the AT support protocol type attribute in the session information.

 Step 203: In the case of the Dormant state switch, the source AN1 sends an A13-Session Information Request message to the target AN2, where the A13 session information request message carries session information of the source AN1 and the AT, the session information refers to the source. The parameters negotiated by AN1 and AT are saved at the same time, including the AT support protocol type attribute.

 Step 204: After receiving the A13 session information request message, the target AN2 saves the session information of the source AN1 and the AT, where the session information includes the AT support protocol type attribute.

 Step 205: The target AN2 sends an A13-Session Information Response message to the source AN1.

 Step 206: After receiving the A13 session information response message, the source AN1 releases the session between the source AN1 and the AT, and sends an A13-Session Information Confirm message to the target AN2, indicating that the session of the source AN1 and the AT has been released. The migration was successful.

 Step 207: The target AN2 determines whether a reconfiguration negotiation needs to be initiated.

For example, when the protocol type supported by the current session and the target AN2 is inconsistent, the target AN2 supports a certain protocol type, such as broadcast multicast, but the current session result is not supported by the protocol type, and the current session refers to the source AN1. The AT information supported in the passed session information is supported. All protocol type information. The target AN2 determines whether it is necessary to initiate reconfiguration negotiation according to the protocol type supported by the AT. The judgment criteria are as follows:

 When the AT supports the protocol type, the target AN2 needs to initiate a reconfiguration negotiation;

When the protocol type is not supported, the target AN2 does not need to initiate reconfiguration negotiation.

 In the case of the connection state switching, the same as the above-mentioned Dormant state switching, the main difference is:

 The A13 session information request message is replaced by an A16-Session Transfer Request message.

 The A13 session information response message is replaced by an A16-Session Transfer Response message;

 The A13 session information confirmation message is replaced by an A16-Session Transfer Complete message.

 An embodiment of the present invention provides a source access network, as shown in FIG. 3, including:

 The receiving module 31 is configured to receive all protocol type information supported by the terminal reported by the terminal. The storage module 33 is configured to save all protocol type information supported by the terminal received by the receiving module 31.

 The source access network may further include:

 The first message sending module is configured to send an A13 session information request message or an A16 session delivery request message.

 The source access network may further include:

 The second message sending module is configured to send an A13 session information confirmation message or an A16 session delivery completion message.

 A target access network, as shown in FIG. 4, includes:

The receiving module 41 is configured to receive all protocol type information supported by the terminal sent by the source access network. The storage module 43 is configured to save all protocol type information supported by the terminal received by the receiving module 41. The target access network may further include:

 The response message sending module is configured to send an A13 session information response message or an A16 session delivery response message.

 The target access network may further include:

 The determining module is configured to determine whether a reconfiguration negotiation needs to be initiated.
