State query and access method and device of home base station gateway

Abstract

The invention discloses a state query method of a home base station gateway, which includes: before the home base station establishes a flow control transmission protocol coupling with the home base station gateway, sending a state query message to all home base station gateways connected to the home base station gateway; The home base station obtains the status information of each home base station gateway according to the status query response message of the home base station gateway. The present invention also discloses a method for accessing a home base station gateway. On the basis of the aforementioned state query method of the home base station gateway, a step is added: the home base station selects the access home base station gateway according to the state information of each home base station gateway and access. The invention also discloses corresponding devices for realizing the aforementioned two methods. The invention not only improves the access success rate of the home base station, but also ensures effective transmission of user service data in the home base station, makes the service load of the home base station gateway more balanced, and improves user experience.

Description

technical field [0001] The present invention relates to the access technology of the home base station, in particular to a method and device for inquiring about the status of the home base station gateway, and a method and device for accessing the home base station gateway. Background technique [0002] figure 1 It is a schematic diagram of the composition structure of the long-term evolution (LTE, LongTermEvolution) system, such as figure 1 As shown, the LTE system mainly includes: a core network (CN, CoreNetwork) and an evolved terrestrial radio access network (E_UTRAN, EvolvedUniversalTerrestrialRadioAccess), and the core network mainly includes a mobility management entity (MME, MobilityManagementEntity) and a serving gateway (S-GW, ServingGateway), the access network is composed of a base station (eNB), a home base station (HeNB) and a home base station gateway (HeNBGW, HeNBGateway), and the core network and the access network are connected through S1 (the interface be...

Problems solved by technology

However, if the HeNBGW is in an overloaded state before the SCTP layer is established, and the HeNB does not know it, if the HeNB establishes a connection with the HeNBGW in the overloaded state, it will affect the use effect of all users under the HeNB, and it will also aggravate the HeNBGW. The business load will cause relatively long user service connection delay and affect user satisfaction.
