METHOD AND DEVICE FOR IMPLEMENTING INSTANT MESSAGING OF MOBILE USER EQUIPMENT

摘要

The present invention provides a method and a device for implementing instant messaging for a Mobile User Equipment (M-UE). The method comprises: a Mobile Gateway (M-GW), after receiving a login request from the M-UE, sends a login authentication request which contains information that a temporary password is required to be allocated to an instant messaging system to acquire an authentication result and the temporary password from the instant messaging system; after acquiring the authentication result and the temporary password, the M-GW allocates a piece of token information to the M-UE and returns the authentication result and the token information to the M-UE; the M-GW replaces the M-UE to complete the subsequent login and live-keeping flow via the temporary password and returns the result to the M-UE, to facilitate the M-UE and the instant messaging system to carry out instant messaging; and when the network between the M-GW and the M-UE is abnormal, the M-GW caches a message which is sent from the instant messaging system to the M-UE so that the M-UE acquires the message cached by the M-GW via the token information after the network between the M-GW and the M-UE goes back to normal.
