101. the first user equipment attaches in the local network using its home subscriber identity.

Specifically, the home subscriber identity may be a telephone number of the first user equipment in its home location, for example, if the operator corresponding to the first user equipment is a china mobile, the home subscriber identity may be a telephone number allocated to the first user equipment by the china mobile, and of course, the home subscriber identity may also be another unique identity allocated to the first user equipment by the home operator, which is not described herein again. When the first user equipment is attached to the local network, it may be attached to the local network through its home subscriber server.

102. And after the first user equipment is attached in the local network, the local mobility management entity judges whether the first user equipment establishes an IMS bearer.

103. And if the first user equipment does not establish the IMS load, the local mobility management entity sends a local user identification request message to the local user server.

104. And the local user server distributes a local user identifier for the first user equipment according to the local user identifier request message.

Specifically, the local user server may allocate a local user identifier in an idle state to the first user equipment in the local user identifier pool, where the local user identifier may be a local phone number or another identifier used for distinguishing different user equipments, and the local user identifier has uniqueness, and the specific local user identifier is not described herein any more.

105. And the local user server returns a local user identification response message carrying a local user identification to the local mobility management entity.

106. The local mobility management entity sends a VOIP (Voice over IP) registration request message to the local VOIP AS server, wherein the VOIP registration request message carries the local user identifier and an IP (Internet Protocol) address of the first user equipment in the local network.

Specifically, when the first user equipment attaches, the local network may assign an IP address of the local network to the first user equipment, and the first user equipment may communicate with the local network through the IP address. When sending the VOIP registration request message to the local VOIP AS server, the following two steps can be implemented: step 1, a local mobility management entity sends a VOIP registration request message to a local GMSC (Gateway Mobile Switching Center); and step 2, the local GMSC sends the VOIP registration request message to a local VOIP AS server.

107. And the local VOIP AS server performs VOIP registration for the first user equipment according to the local user identification and the IP address so AS to obtain VOIP configuration parameters.

Specifically, in the above manner, the first user equipment is registered in the local network, and the obtained VOIP configuration parameters include VOIP setting parameters of the local network, before the first user equipment performs the voice service with the local network, the first user equipment needs to modify the VOIP setting parameters of the first user equipment into corresponding VOIP setting parameters, so that the first user equipment performs the voice service according to the corresponding VOIP setting parameters and the local user identifier allocated to the first user equipment.

108. And the local VOIP AS server sends VOIP registration response information to the local mobility management entity, wherein the VOIP registration response information carries the VOIP configuration parameters.
