Abstract
The invention provides a method for realizing load migration of a home base station gateway. The method comprises the following steps: 1, a home base station served by a source home base station gateway transmits a registration request to the source home base station gateway, and the source home base station gateway returns a registration reject message which carries an identifier of a migration destination home base station gateway to the home base station; 2, the home base station retransmits the registration request to the migration destination home base station; and 3, the migration destination home base station gateway returns a registration acceptance message to the home base station. When a certain home node B gateway (H(e)NB GW) in a H(e)NB GW pool area is required to be uninstalled due to overload, upgrade and the like, a H(e)NB on the H(e)NB GW can be migrated to a specified H(e)NB GW in the pool area according to the the load migration method provided by the invention, so that the utilization ratio of the H(e)NB GW in the pool area is increased.
Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a kind of method that realizes load migration of home base station gateway.
Background technology
In order to keep 3-G (Generation Three mobile communication system) in the competitiveness of the communications field, for the user provides that speed is faster, time delay is lower, Extraordinary Mobile Communication Service more, reduce simultaneously the operation cost of operator, third generation partner program (3rd Generation Partnership Project, abbreviation 3GPP) the standard operation group just is being devoted to the evolution system research of (Evolved Packet System is called for short EPS).Whole EPS system is divided into wireless network (Evolved Universal Terrestrial Radio AccessNetwork is called for short E-UTRAN) and core net (Evolved Packet Core, abbreviation EPC) two parts.
In core net, comprised assigned user server (Home Subscriber Server, abbreviation HSS), mobility management unit (Mobility Management Entity, abbreviation MME), policy charging rule function (Policy and Charging Rule Function, abbreviation PCRF), gateway (Serving Gateway, be called for short S-GW) and packet data gateway (PDN Gateway is called for short P-GW).
In wireless network, comprised evolution base station (E-UTRAN Node B is called for short eNB), it mainly is responsible for the transmitting-receiving of wireless signal, by air interface and terminal contact.Simultaneously, introduce Home eNodeB (Home (e) Node B is called for short H (e) NB) in wireless network, as a kind of of network replenished.H (e) NB is a kind of novel miniaturization, low power base station form, mainly is deployed in the indoor environments such as family or office, has low cost, accesses conveniently, enlarges the advantages such as covering, raising capacity.
Fig. 1 is the network configuration of Home eNodeB in evolvement network, and comprising Home eNodeB, femto gateway (H (e) NB Gateway is called for short H (e) NB GW), Home eNodeB is connected to core net by femto gateway.All Home eNodeB all will be connected on femto gateway, just can be linked into evolution system after the checking of Home eNodeB through femto gateway.Femto gateway is mainly carried out following basic function: the fail safe of checking Home eNodeB, process the registration of Home eNodeB, and be intermediary's network element of the S1 interface between Home eNodeB and core net, core net and Home eNodeB are by the femto gateway swap data.
When family's base-station gateway need to be upgraded or during femto gateway load abnormal, its Home eNodeB of serving just can't be registered immediately.
Summary of the invention
For the defective that exists in prior art and deficiency, the objective of the invention is to propose a kind of method that realizes load migration of home base station gateway, need to upgrade at femto gateway or during femto gateway load abnormal, its Home eNodeB of serving can also be registered at once.
In order to achieve the above object, the present invention proposes a kind of method that realizes load migration of home base station gateway, comprising:
The Home eNodeB of step 1, source femto gateway service sends registration request to the source femto gateway, and the source femto gateway returns to registration reject message with the sign of move target femto gateway to described Home eNodeB;
Step 2, described Home eNodeB resend registration request to the move target femto gateway;
Step 3, move target femto gateway return to registration to described Home eNodeB and accept message.
Preferred as technique scheme, the sign of described move target femto gateway are to be noted abnormalities by the loading condition that the Home eNodeB management system monitors the source femto gateway distribute when needing unloading and send described source femto gateway to.
When certain H (e) NB GW in the district of H (e) NB GW pond need to unload due to reasons such as excess load, upgradings, the method of the load migration that can propose according to the present invention moves to H (e) NB on this H (e) NB GW on H (e) the NB GW of appointment in the district of pond, has improved the utilance of H (e) NBGW in the district of pond.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.For the person of ordinary skill in the field, from detailed description of the invention, above and other purpose of the present invention, feature and advantage will be apparent.
Fig. 1 is the schematic network structure of Home eNodeB in the evolvement network of prior art;
Fig. 2 is the schematic flow sheet of the preferred embodiment of the present invention.
Embodiment
Be below the preferred embodiments of the present invention, as shown in Figure 2, a kind of method that realizes load migration of home base station gateway comprises the following steps:
H (e) NB of step 101, source H (e) NB GW service sends registration request to source H (e) NB GW;
Step 102, source H (e) NB GW return to the registration reject message of the sign (H (e) NB GW ID) with move target H (e) NBGW to described H (e) NB, and BackoffTime is set to 0;
Step 103, described H (e) NB resend registration request according to described sign to move target H (e) NB GW;
Step 104, purpose H (e) NB GW return to registration to described H (e) NB GW and accept message.
Wherein, described source H (e) NB GW represents needs H (e) the NB GW that unloads in the district of H (e) NB GW pond, the named place of destination of move target H (e) NB GW representative migration.
Wherein Backoff Time is back off time, refer to that the wait after H (e) NB transmission registration request is rejected resends the time of registration request next time, and here, although H (e) NB sends registration request first be rejected after, owing to obtaining move target H (e) NB GW ID, therefore need not to keep out of the way, this Backoff Time is set to 0, and can at once again send registration request to move target H (e) NB GW, thereby improve the utilance of H (e) NB GW in the district of pond.
In the above-described embodiments, move target H (e) NB GW forms like this: the loading condition of Home eNodeB management system (HMS) monitoring H (e) NB GW, when noting abnormalities, in the time of need to unloading the H in the district of pond (e) NB GW, HMS is that H (e) NB GW to be unloaded is that source H (e) NBGW distributes new move target H (e) NB GW, and in real time the sign (H (e) NB GW ID) of purpose femto gateway is sent to the femto gateway (being the source femto gateway) of needs unloading.
By said method, realized H (e) NB is moved to from source H (e) NB GW the process of purpose H (e) NBGW.That is to say, the present invention can move to H (e) NB on H to be unloaded (e) NB GW and specify on H (e) NB GW, has improved the utilance of H (e) NB GW in the district of pond.
Although; the present invention clearly demonstrates by above embodiment and accompanying drawing thereof; yet in the situation that do not deviate from spirit of the present invention and essence thereof; the person of ordinary skill in the field works as can make according to the present invention various corresponding variations and correction, but these corresponding variations and correction all should belong to the protection range of claim of the present invention.
