Method, device and system for sending participating service provider identity

A method for transmitting a Participating Service Provider (PSP) identity, comprising:

• transmitting a broadcast indicating short PSP identities corresponding to long PSP identities supported by a Neutral Host (NH) network access device;
• receiving a first communication protocol message returned from a client, the first communication protocol message carrying compressed information of a long PSP identity to be accessed;
• and
• generating a second communication protocol message based on the first communication protocol message, the second communication protocol message indicating whether the NH network supports the long PSP identity.

A device for transmitting a Participating Service Provider (PSP) identity, comprising:

• an information parsing means configured to parse a previously received broadcast that is transmitted by a Neutral Host (NH) network access device to determine whether a first short PSP identity corresponding to a long PSP identity to be accessed exists in a first short PSP identity list in the broadcast;
• an information transmitting means configured to transmit a first communication protocol message to the NH network access device when it is determined that the first short PSP identity exists in the first short PSP identity list, the first communication protocol message carrying compressed information of the long PSP identity to be accessed;
• and
• an information receiving means configured to acquire a second communication protocol message transmitted by the NH network access device, the second communication protocol message indicating whether an NH network supports the long PSP identity.

A system for transmitting a Participating Service Provider (PSP) identity, comprising:

• a Neutral Host (NH) network access device and a client which are communicatively connected with each other, wherein the client is a device for transmitting the PSP identity, and the NH network access device is a device for transmitting the PSP identity,
• the device for transmitting the PSP identity comprises:
• an information parsing means configured to parse a previously received broadcast that is transmitted by the NH network access device to determine whether a first short PSP identity corresponding to a long PSP identity to be accessed exists in a first short PSP identity list in the broadcast;
