Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
As shown in fig. 1, the present embodiment provides a method for accessing a service, which includes:
step 11: and the network side equipment sends a message to the UE, wherein the message contains an indication whether the IMS network supports the 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 or not, and the condition 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 method for service access, including:
step 21: and the UE receives a message sent by the network side equipment, wherein the message contains an indication whether the IMS network supports the 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 or not, and the condition 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.
Example 2
This example is a further limitation of example 1. In the method for accessing a service according to this embodiment, the network side device may include a P-CSCF (Proxy-Call Session Control function) server, that is, the P-CSCF server may notify the UE whether the IMS network supports the Ut interface. Specifically, step 11 may specifically include: the P-CSCF server sends a registration reply message to the UE in response to the UE-initiated IMS registration request. The registration reply message includes first indication information, and the first indication information is used for indicating whether the current IMS network supports the Ut interface. Of course, the registration reply message may include information related to the existing registration reply message in addition to the first indication information.
The P-CSCF server may determine, according to the locally configured Ut information, that the first indication information indicates that the current IMS network supports the Ut interface or does not support the Ut interface.
Further, when the first indication information indicates that the current IMS network supports the Ut interface, the first indication information may further include location information supporting the Ut interface, such as a TA/TA list (Tracking Area). The location information may facilitate the UE to further determine whether the current location is within the range of the location information, and if so, the first indication information is valid, and the UE may initiate the Ut interface connection.
When the network side device includes a P-CSCF server, step 21 may specifically include: the UE receives a registration reply message which is sent by the P-CSCF server and responds to an IMS registration request initiated by the UE, wherein the registration reply message comprises first indication information, and the first indication information is used for indicating whether the current IMS network supports a Ut interface.
Further, when the first indication information indicates that the current IMS network supports the Ut interface and further includes location information supporting the Ut interface, step 22 may specifically include the UE determining whether the current location is within the range of the location information, if so, the first indication information is valid, and the UE initiates a Ut interface connection.
The method of this embodiment may notify the UE of "whether the IMS network supports the Ut interface" in the registration reply message through the P-CSCF server during the IMS registration. Correspondingly, the UE also receives a registration reply message of the P-CSCF server to know whether the IMS network supports the Ut interface or not.
Fig. 3 shows the complete procedure for IMS registration by the UE. It includes:
step 31: UE selects a wireless network and initiates wireless connection, wherein the wireless network carries a registration request;

step 33: the wireless access network forwards the registration completion message to the UE to complete the access and registration process of the UE;
step 34: UE initiates an IMS registration request to a P-CSCF server;
step 35: after authenticating and authenticating the UE, the P-CSCF server sends a registration reply message to the UE by combining with locally configured Ut information, wherein the registration reply message contains first indication information and indicates whether the current IMS network supports the Ut interface, and if so, the first indication information also comprises the position information supporting the Ut interface, such as a TA/TA list;
step 36: and the UE judges whether the IMS network supports the Ut interface according to the received registration reply message, if so, further judges whether the current position of the UE is in the range of the position information, if so, the first indication information is valid, the UE initiates the connection of the Ut interface and starts a supplementary service data configuration flow on the Ut interface, otherwise, the UE does not initiate the connection of the Ut interface.
Example 3
This example is a further limitation of example 1. In the method for service access according to this embodiment, the network side device may include a core network server, that is, the core network server may notify the UE whether the IMS network supports the Ut interface.

The registration access reply message may include Attach Accept or TAU Accept, among others. An IMS-APN indicating that the current IMS network supports the Ut interface may be denoted as Ut.
Further, when the second indication information indicates that the current IMS network supports the Ut interface, the second indication information further includes location information supporting the Ut interface, such as a TA/TA list. The location information may facilitate the UE to further determine whether the current location is within the range of the location information, and if so, the second indication information is valid, and the UE may initiate a Ut interface connection.
When the network-side device includes a core network server, step 21 may include: and the UE receives a registration access reply message which is sent by a core network server and responds to a core network registration access request initiated by the UE through a wireless access network, wherein the registration reply message comprises an IMS-APN carrying second indication information, and the second indication information is used for indicating whether the current IMS network supports a Ut interface. The registration access reply message may include Attach Accept or TAU Accept, among others. An IMS-APN indicating that the current IMS network supports the Ut interface may be denoted as Ut.
