Abstract

A method for a dual-mode terminal in a HRPD network to respond to 1× paging, the method comprising steps of: after a MS/AT turns to the HRPD network and informs a MSC of the related information via PCF, the MSC sending a 1× service arrive notification message to the MS/AT via PCF including a calling party number if some 1× paging information arrives; after receiving the 1× paging, the MS/AT displaying the calling party number to a user and waiting for the choice of the user; the MS/AT terminating service in the HRPD network and switching into a 1× network to send a “Page Response” message to the 1× BS if the user chooses to accept the 1× call; if the user rejects to accept the 1× call, the MS/AT sending a user response rejection message to an AN, the AN forwarding it to the PCF to indicate that the user can not accept this 1× call; after receiving the user response rejection message, the PCF constructing a “Paging Response” message and sending it to the MSC to inform the MSC to terminate this call; and after receiving the rejection message from the PCF, the MSC terminating this call and releasing relevant resources.

Claims

1. A method for a dual-mode terminal in a HRPD network to respond to 1×

paging, the method comprising steps of;

a) sending a message by a MSC via PCF to the MS/AT to indicate a 1×

service arrival;

b) after receiving the message to indicate 1×

service arrival, displaying the calling party information by the MS/AT to a user and waiting for the choice of the user;

c) turning to a 1×

network by the MS/AT to send a Page Response Message to the 1×

BS if the user chooses to accept the 1×

call;

d) if the user chooses not to accept the 1×

call, sending a message by the MS/AT to indicate user'"'"'s refusal to an AN, and transferring the message by the AN to the PCF;

e) after receiving the message to indicate user'"'"'s refusal, the HRPD PCF constructing a corresponding Rejection message and sending it to the MSC to inform the MSC to terminate this call; and

f) after receiving the Rejection message from the HRPD PCF, the MSC terminating this call and releasing relevant resources.

2. The method according to claim 1, wherein the message sent by a MSC to indicate a 1×

service arrival includes calling party information.

3. The method according to claim 1, wherein when waiting for the choice of a user, the MS/AT does not turn to the 1×

network, and if the MS/AT is in HRPD connection state, no interrupt is caused to the HRPD connection when displaying the calling party number or waiting for the choice of the user.

4. The method according to claim 1, wherein the choice of the user can be from the user'"'"'s operation each time through man-machine interface.

5. The method according to claim 1, wherein choice of the user can be from the preset settings by the user for all 1×

calls or some specific calling party numbers, and the MS/AT operates automatically according to the preset settings.

6. The method according to claim 1, wherein if the user chooses to accept the 1×

call, the MS/AT automatically turns to the 1×

network.

7. The method according to claim 1, wherein when the user refuses to accept the call, a 3G1×

MS rejection order is used for the response message sent from the called MS/AT to the HRPD AN to indicate the user'"'"'s refusal.

8. The method according to claim 1, wherein after receiving the message to indicate user'"'"'s refusal forwarded by the AN, the HRPD PCF informs the MSC to terminate this call by adding a new field in the Paging Response message indicating the user'"'"'s refusal.

9. The method according to claim 1, wherein after receiving the message to indicate user'"'"'s refusal forwarded by the AN, the HRPD PCF informs the MSC to terminate the call by setting the radio environment and resource option as “

not available”

in the Paging Response message.

10. The method according to claim 1, wherein after receiving the message to indicate user'"'"'s refusal forwarded by the AN, the HRPD PCF informs the MSC to terminate the call in virtue of a Rejection message.
