Example 1
As shown in fig. 1, this embodiment provides a method for service access, which includes:
Step 11: the network side equipment sends a message to the UE, wherein the message contains an indication of whether the IMS network supports a Ut interface.
In the method, the network side equipment informs the UE whether the IMS network supports the Ut interface or not through the sent message, so that the UE can conveniently judge whether to initiate the Ut interface connection, and the situation that the request fails because the IMS network does not support the Ut interface after the UE initiates the Ut interface connection request is avoided.
As shown in fig. 2, this embodiment further provides a service access method, including:
Step 21: the UE receives a message sent by the network side equipment, wherein the message contains an indication of whether the IMS network supports a Ut interface.
Step 22: and the UE judges whether to initiate the Ut interface connection according to the message. If the message indicates that the IMS network supports the Ut interface, the UE initiates the Ut interface connection, and if the message indicates that the IMS network does not support the Ut interface, the UE does not initiate the Ut interface connection.
In the method, the UE acquires whether the IMS network supports the Ut interface or not through the received message, so as to judge whether to initiate the Ut interface connection, and avoid the situation that the request fails because the IMS network does not support the Ut interface after the UE initiates the Ut interface connection request.
