Problems solved by technology

[0005] To sum up, the inventor discovered during the invention process that there are multiple access modes in a certain access domain, but the existing technology cannot solve the problem of multi-mode terminal How does the network select the access mode and indicate the call connection when the callee is called
That is, after the routing decision-making entity selects the access mode according to a certain policy, it cannot instruct the routing execution entity to perform call connection in the selected access mode.

Embodiment 1

[0058] Embodiment 1. When the terminal establishes a registration connection, it notifies the network side of the current access mode type and the instance_id bound to the current access mode type; the network side associates the access mode type notified by the terminal with the allocated GRUU; the application server It is determined that there is a media component in the call session message, and there is no need to split the media component; when connecting to the called party, the routing decision-making entity selects an access mode for the call session message; finally, the routing decision-making entity uses the selected access mode The GRUU corresponding to the entry mode type instructs the routing execution entity to perform call connection. see Figure 4 shown, including the following steps:

[0059] 1: The multi-mode terminal accesses the IMS network from WLAN, initiates a registration request REGISTER, and adds the +sip.instance parameter in the contact header fie...

Embodiment 2

[0072] Embodiment 2. When the terminal establishes a registration connection, it notifies the network side of the current access mode type and the instance_id bound to the current access mode type; the network side associates the access mode type notified by the terminal with the allocated GRUU; the application server Determine that there are multiple media components in the call session message, and decide to split the session message according to different media components according to a certain strategy; then, when connecting to the called party, the routing decision-making entity separately divides each media component The flow selects the access mode; finally, the GRUU corresponding to the selected access mode is used to instruct the routing execution entity to continue the media flow. see Figure 5 shown, including the following steps:

[0073] 1: The multi-mode terminal accesses the IMS network from WLAN, initiates a registration request REGISTER, and adds the +sip.ins...

Embodiment 3

[0104] Embodiment 3: The application server determines that there are multiple media components in the call session message, and decides to split the session message according to different media components according to a certain strategy.

[0105] In this embodiment, a feature tag is added to identify the access network type. Assume that the name of the newly added feature tag is accesstype, and the value can be "wlan", "wcdma", etc., to identify various access modes.

[0106] see Figure 7 shown, including the following steps:

[0107] 1. The multi-mode terminal accesses the IMS network from the WLAN, initiates a registration request REGISTER, and the request message carries the contact_1 address, and the contact header field is followed by the accesstype parameter that identifies the type of access network. The parameter is assigned to wlan, indicating access from the WLAN network . After the request message is forwarded by the corresponding entity, it reaches the S-CSCF (...

Abstract

The present invention publicly provides the method, system and device to provide the access mode selection for the multi -mode terminal, so that the route decision entity can select the access mode according to a certain strategy, and the routing execution entity can be executed by the selected access mode for the call continuation.EssenceThe method of the present invention includes: When the terminal establishes a registered connection, the name of the current access mode type and binding the current access mode type type of resource name will be notified;The global routing user agent of this terminal allocated the uniform resource identifier GRUU, which is associated with the two; and when the call for the call is called, the routing decision entity on the network side isGRUU indicates that the routing execution entity performs the call continuation.

Description

Technical field [0001] The present invention involves the method, system, and device that involves the method, system and device that provides access mode for multi -mode terminals. Background technique [0002] IMS is an IP multimedia subsystem in the WCDMA network defined by the 3GPP R5 / R6 standard. It is a 3G mobile network to implement the distribution voice and group data, which provides a unified multimedia business and application target network.The IMS uses the IP packet domain as the carrying channel for its control message and media transmission, and uses the SIP protocol as a call control message.In IMS, the IMS user signing data concentration is managed in HSS. The business is provided by the application server AS.Multiple AS can work together.Users can access IMS through the current proxy node P-CSCF, and session and business control are completed by its registered land service node. Therefore, users can always get the same service at different access points, realiz...
