The first backhaul network load bearing management method flow chart that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the backhaul network load bearing management method that the present embodiment provides specifically can be applied to the bearer management process of the communication system that is provided with backhaul network.This communication system is specifically as follows LTE (Long TermEvolution, Long Term Evolution) communication system or UMTS (Universal Mobile TelecommunicationsSystem, universal mobile telecommunications system), take LTE communication system as example, LTE communication system specifically can comprise grouped data network gateway (Packet Data Network Gateway, be called for short PDN GW), gateway (Serving Gateway, be called for short Serving GW), Mobility Management Entity (MobilityManagement Entity, be called for short MME), base station (evolved Node B, be called for short eNB) and backhaul node etc.In communication system, domestic consumer's equipment (hereinafter to be referred as conventional equipment) can be by access network and backhaul network Access Core Network, and conventional equipment is via backhaul node and eNB Access Core Network.Backhaul network and access network can use identical or different frequency and standard, for example, backhaul network uses LTE TDD (time-division duplex, time division duplex) as backhaul transport, access network can use GSM (Global System ofMobile communication, global system for mobile communications), UMTS, Wi-Fi (Wireless Fidelity, Wireless Fidelity) and LTE FDD (Frequency DivisionDuplexing, full duplex) one or more standards in/TDD, backhaul network is access network transparent transmission user data.Conventional equipment can also be directly by eNB Access Core Network.

The backhaul network load bearing management method that the present embodiment provides specifically comprises:

Steps A 10, first network equipment receive the Attach Request message that carries device parameter, and wherein, described device parameter is for identifying user equipment, and described device parameter comprises international mobile subscriber identity;

Particularly, when subscriber equipment access network, initiate attachment flow, it can be also backhaul node that this subscriber equipment is specifically as follows conventional equipment, subscriber equipment sends Attach Request message to the network equipment of network side, in this Attach Request message, carry device parameter, device parameter specifically can be for identifying user equipment, and device parameter comprises international mobile subscriber identity (International Mobile SubscriberIdentification Number is called for short IMSI).If initiating the subscriber equipment of attachment flow is backhaul node, in this device parameter, can also comprise identity indication information, it is backhaul node that this identity indication information can be indicated this subscriber equipment.

In LTE communication system, MME can realize first network equipment, and certainly, in other communication systems, first network equipment can adopt the network element of similar functions to realize.Take LTE communication system as example, the process that first network equipment receives Attach Request message is specifically as follows: subscriber equipment sends Attach Request message to eNB, and this Attach Request message is sent to MME by eNB, i.e. first network equipment.

Steps A 20, described first network equipment judges according to described device parameter whether the subscriber equipment that request is adhered to is backhaul node, if, send and create conversation request message to second network equipment, wherein, in described establishment conversation request message, carry described international mobile subscriber identity, the mark of default bearing and the mark of at least two dedicated bearers, so that described second network equipment is set up described default bearing and described at least two dedicated bearers according to the described backhaul node of being designated of the mark of the described default bearing in described establishment conversation request message and described at least two dedicated bearers.

Particularly, first network equipment judges that according to device parameter whether the subscriber equipment that adheres to of request is that the mode of backhaul node can have multiple:

In one implementation, if the subscriber equipment that request is adhered to is backhaul node, device parameter comprises identity indication information and IMSI, if the subscriber equipment that request is adhered to is conventional equipment, in facility information, does not comprise identity indication information.If first network equipment recognizes device parameter while comprising identity indication information, obtain the CAMEL-Subscription-Information of this subscriber equipment, if it is backhaul node that this CAMEL-Subscription-Information is also indicated the identity of this subscriber equipment, be proved to be successful, this subscriber equipment is backhaul node, if authentication failed, refuses this subscriber equipment access.CAMEL-Subscription-Information specifically can be stored in home subscriber server (Home SubscriberServer, be called for short HSS) in, first network equipment can inquire about to obtain by IMSI the CAMEL-Subscription-Information of subscriber equipment to HSS, also can directly IMSI be sent to HSS, HSS carries out authentication by IMSI to subscriber equipment, return to the identity indication information of this subscriber equipment, the identity indication information that first network equipment returns to the identity indication information in device parameter and HSS is compared, if consistent, this subscriber equipment is backhaul node, if inconsistent, refuse this subscriber equipment access.

In the second implementation, no matter subscriber equipment is backhaul node or conventional equipment, in this device parameter, do not comprise identity indication information, the CAMEL-Subscription-Information of storing in HSS comprises identity indication information.First network equipment can obtain the CAMEL-Subscription-Information that IMSI is corresponding from HSS, according to the identity of this CAMEL-Subscription-Information identification subscriber equipment.

In the third implementation, a field can be set in IMSI in order to indicate the identity of this subscriber equipment, first network equipment can be identified according to the field in this IMSI the identity of this subscriber equipment.

Be understandable that, those skilled in the art can also realize the identification to subscriber equipment by other means, are not limited with the present embodiment.

If the subscriber equipment that request is adhered to is conventional equipment, can process according to the bearer management flow process to conventional equipment of the prior art.

If the subscriber equipment that request is adhered to is backhaul node, first network equipment sends and creates conversation request message to second network equipment, create in conversation request message and carry the mark of this IMSI, default bearing and the mark of at least two dedicated bearers, second network equipment is set up default bearing and at least two dedicated bearers according to the backhaul node that IMSI is corresponding that is designated of the mark of default bearing and at least two dedicated bearers.In actual applications, can there is higher limit for the dedicated bearer quantity that backhaul node is set up, as 8., in the attachment flow of backhaul node, can set up default bearing and all dedicated bearers for backhaul node simultaneously, or set up default bearing and part dedicated bearer for backhaul node, the quantity of this part dedicated bearer is at least two.

In LTE communication system, PDN GW can realize second network equipment, and certainly, in other communication systems, second network equipment can adopt the network element of similar functions to realize.Take LTE communication system as example, the process that first network equipment sends establishment conversation request message to second network equipment is specifically as follows: MME sends and creates conversation request message to Serving GW, and Serving GW sends to PDN GW by this conversation request message again.

Second network equipment is set up corresponding default bearing and dedicated bearer according to the backhaul node that is designated of the mark of default bearing and at least two dedicated bearers.After carrying between backhaul node and second network equipment is successfully established, in the time having conventional equipment access backhaul node, backhaul node is set up the carrying with conventional equipment, in the time that conventional equipment sends upstream data, backhaul node can be according to the type of this upstream data or service quality (Quality of Service, be called for short QoS) carrying between backhaul node and conventional equipment is mapped in the carrying between backhaul node and second network equipment, to realize the transmission of upstream data.In the time that the downlink data corresponding to this conventional equipment arrives second network equipment, second network equipment also can according to the type of downlink data or QoS by and backhaul node between carrying send to backhaul node, backhaul node again by this downlink data by and conventional equipment between carrying send to conventional equipment.

In actual applications, if conventional equipment and backhaul node simultaneously when access network, first network equipment can preferentially be carried out the loading establishing process of backhaul node.

The backhaul network load bearing management method that the present embodiment provides, first network equipment receives the Attach Request message that carries device parameter, wherein, device parameter is for identifying user equipment, device parameter comprises international mobile subscriber identity, judge according to device parameter whether the subscriber equipment that request is adhered to is backhaul node, if, send and create conversation request message to second network equipment, wherein, create in conversation request message and carry international mobile subscriber identity, the mark of default bearing and the mark of at least two dedicated bearers, so that second network equipment is set up default bearing and at least two dedicated bearers according to the mark of default bearing and the backhaul node that is designated of at least two dedicated bearers that create in conversation request message.The differentiation of the identity by backhaul node and conventional equipment, in the time of backhaul node access network, for backhaul node is set up default bearing and at least two dedicated bearers simultaneously, in the time that the conventional equipment quantity accessing by backhaul node is more, avoid repeatedly setting up the growth that the time of service is provided for accessing the conventional equipment of backhaul node that carrying causes, also reduced system signaling expense.
