s101, the gateway equipment establishes a first Gy session.

In this embodiment, the first Gy session is a Gy session of a first service that the terminal needs to access, and after the gateway device determines that the terminal needs to access the first service, the gateway device may establish the Gy session of the first service, where the Gy session of the first service is referred to as a first Gy session. The first service is, for example, hundred degree video.

S102, the gateway equipment sends a first charging request to the OCS, and the OCS receives the first charging request sent by the gateway equipment.

In this embodiment, after establishing the first Gy session, the gateway device sends a first charging request to the OCS, where the first charging request includes a session identifier of the first Gy session and a Rate Group (RG) of the first service, and the first charging request is used to request the OCS to charge the first service through the first Gy session corresponding to the session identifier, according to the RG of the first service. The first charging Request may be a Credit Control Request (CCR) of the first service, such as an initial CCR (initial), that is, CCR-I. Accordingly, the OCS receives the first charging request sent by the gateway device.

Optionally, the first charging request further includes parameter information of the first Gy session, for example: a subscriber Identity, an International Mobile Equipment Identity (IMEI) or a prefix of the IMEI, an Access Point Name (APN), an Internet Protocol (IP) address of a Serving GPRS Support Node (SGSN), and so on. Before executing S103, the OCS stores the parameter information of the first Gy session in the session list of the user of the terminal according to the first charging request, where the session list of the user of the terminal includes the parameter information of the Gy session that the terminal is accessing, and further, the OCS may determine the Gy session that the terminal is accessing, for example, the second Gy session, according to the session list of the user of the terminal. The parameter information of the second Gy session is stored in the session list of the user of the terminal by the OCS receiving the charging request of the second Gy session sent by the gateway device.

S103, the OCS determines to merge the first Gy session and the second Gy session.

In this embodiment, after receiving the first charging request, the OCS determines that the first Gy session may be merged with a second Gy session, where the second Gy session is a Gy session of a second service that the terminal is accessing. The second service is for example WeChat.

In an alternative implementation of S103, the OCS may determine to merge the first Gy session and the second Gy session according to a preset session merging rule, where the preset session merging rule is used to indicate that the first Gy session and the second Gy session need to be merged. An example of the preset session merging rule is shown in table one, but the embodiment is not limited thereto. As can be seen from table one, the group number of the first service is the same as the group number of the second service, and therefore, the Gy session of the first service and the Gy session of the second service can be merged.

Watch 1

S104, the OCS sends a session merging indication message to the gateway equipment, and the gateway equipment receives the session merging indication message sent by the OCS.

In this embodiment, after determining to merge the first Gy session and the second Gy session, the OCS sends a session merging indication message to the gateway device, where the session merging indication message includes a session merging indication, and the session merging indication is used to indicate the gateway device to merge the first Gy session and the second Gy session. The session merging indication message may be a first charging response corresponding to the first charging request, where the first charging response may be a Credit Control response (CCA for short) of the first service, such as an initial CCA (initial CCA), that is, CCA-I, and the session merging indication may be added by extending a Gy interface AVP in the CCA-I in this embodiment.
