Definitions
- the present invention relates to mobile communication technologies, and more particularly to a method of establishing a call connection for a called party. Background of the invention
- FIG. 1 is a flow chart of a prior art setup call connection for a called party.
- the process of establishing a call connection for the called party in the prior art mainly includes the following steps. :
- Step 101 The primary call UE sends a connection related service request (CM Service Request) message carrying the service type information to the core network (CN), and the CN sends a connection related service response (CM Service Accept) message to the primary call UE.
- CM Service Request connection related service request
- CN core network
- the CM Service Request message sent by the calling UE to the CN includes the service quality of service (QoS) parameter of the current call.
- QoS quality of service
- Step 102 The CN sends a paging (PAGING) message to all the RNCs corresponding to the location area of the called UE, and all the RNCs send a paging type 1 message, and the called UE receives the paging type 1 message and completes the RRC with the RNC. Connection establishment process.
- PAGING paging
- Step 103 The called UE sends a PAGING Response message to step 104: After receiving the PAGING Response message, the CN sends a Setup message to the called UE, and the called UE confirms the call (Call Confirm). The message is sent to the CN. Here, the CN sends the Setup message to the called UEc after receiving the Setup message sent by the calling UE.
- Step 105 The CN sends a radio access bearer assignment (RAB Assignment) message to the RNC, where the message includes the QoS parameters of the current call.
- RAB Assignment radio access bearer assignment
- Step 106 The RNC maps the radio interface parameters according to the service quality parameter in the RAB ASSIGNMENT message, and performs a radio access bearer (RB) connection establishment process of the called UE.
- RB radio access bearer
- Step 107 After the RB connection is established, the RNC sends a radio access bearer assignment response (RAB ASSIGNMENT RESPONSE) message to the CN, indicating that the service assignment is completed.
- RAB ASSIGNMENT RESPONSE radio access bearer assignment response
- Step 108 The called UE sends a Belling Indication (Alerting) message to the CN, and the CN sends the Alerting message to the calling UE, and the calling UE hears the ringback tone.
- a Belling Indication (Alerting) message to the CN
- the CN sends the Alerting message to the calling UE, and the calling UE hears the ringback tone.
- Step 109 The called UE sends a CONNECT message to the CN, and the core network sends the CONNECT message to the calling UE, and the calling party and the called user implement the call.
- the first time between the called UE and the CN is required to perform an interactive paging PAGING message and a paging response PAGING Response message.
- the interaction process, and the second interaction process of interacting to establish a Setup message and a call confirmation Call Confirm message Only this second interaction process takes about 300ms, which greatly increases the time taken to establish a call connection.
- the CN can send the RAB ASSIGNMENT message carrying the QoS parameter to the RNC to trigger the service RB establishment process.
- the QoS parameter is determined when the CN receives the CM Service Request message sent by the calling UE. That is, the CN has obtained the QoS parameters transmitted by the RAB ASSIGNMENT message before the called UE performs the RRC connection establishment process, but The CN does not send the determined QoS parameters to the RNC as soon as possible to perform the service RB establishment process as soon as possible, but delays the transmission of the QoS parameters until the RC connection established by the UE is established. Therefore, the QoS parameter is It greatly increases the time taken to establish a call connection.
- the automatic answering function is set for the called UE, after the signaling and the service are established, that is, after the CN receives the RAB ASSIGNMENT RESPONSE message sent by the RNC of the calling UE and the called UE, the calling UE and the calling UE.
- the called link between the called UEs is already established, and the called UE only needs to send the CONNECT message to the primary calling UE through the CN, and does not need to send the ringback Alerting message.
- the called UE is still in the call.
- the method of sending an Alerting message to the calling UE after the link is established greatly increases the time taken to establish a call connection. Summary of the invention
