Embodiment 1

[0058] Embodiment 1: A solution in which the user acts as the calling party.

[0059] Such as image 3 As shown, it is a schematic flow chart of the present invention when the user acts as a caller. As can be seen from the figure, it mainly includes the following steps:

[0060] S11. The UE sends a cell update message to the SRNC, and the cell update message carries a service request.

[0061] When the user initiates a call service as the calling party, the UE judges whether message combination is required for this call. If message combination is used this time, the UE carries the service request message in the update message, and the indicator bit indicates that the service request message is included.

[0062] For the update message in step S11, if the user is on CELL_PCH, then the cell update message is sent, and if the user is on URA_PCH, then the URA update message is sent. This embodiment uses the cell update message.

[0063] The cell update message in step S11 may b...

Embodiment 2

[0084] Embodiment 2: The scheme in which the user is called.

[0085] In Embodiment 2, the user, as the called party, receives the data transmission request sent by the CN. The terminal is currently in the URA_PCH state and can only receive paging messages, and the SRNC sends paging type 1 messages on the downlink paging channel.

[0086] Such as Figure 4 As shown, it is a schematic flow diagram of the user as the called party in the present invention. As can be seen from the figure, it mainly includes the following steps:

[0087] S21. The CN sends a data transmission request to the SRNC.

[0088] S22. The SRNC sends a paging type 1 message on the downlink paging channel.

[0089] The SRNC connected with the UE knows that the UE is currently in the CELL_PCH (or URA_PCH) state and can only receive paging messages, and the SRNC sends paging type 1 messages on the downlink paging channel.

[0090] S23. The UE sends a cell update message to the SRNC, where the cell update me...

Abstract

The method comprises: a) terminal sends the update message to the controller of serving radio network; the update message carries the service request; b) the controller of serving radio network sends the service request to the core network; c) the terminal is switch into a private connection state to connect to core network. The system thereof comprises: the terminal comprising a message combination unit for setting the service request in the update message transmitted to the core network; the core network comprising message processing unit for receiving the update message and making service connection for the terminal according the service request; and a controller of serving radio network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for establishing a fast connection when there are CS Circuit Switched connections and PS Packet Switched connections between a terminal and a network. Background technique [0002] The trunking wireless communication system is a special mobile radio system or a dedicated mobile radio system, which mainly provides communication services such as production dispatching and command control for professional companies operating outdoors and mobile users of business departments. Because the system has the advantages of easy to use, fast call establishment and good confidentiality, it is widely used in many special command and dispatch projects such as railway transportation, ship communication, port navigation, aviation business, weather forecast, forestry, mining area operations, public security, electric power, petroleum, disaster relief, etc. It is widely used in the fie...
