Abstract

The invention relates to the wireless communication field, discloses a method and a device for processing bearer identities and enables an EPS bearer to be established and used successfully. In the invention, bearer identities are allocated by MME, PDN GW, Serving GW, or UE; and well-allocated bearer identities are carried by messages in the establishing flow of the bearer and transmitted to each physical device related to the newly-built bearer. During the bearer establishing flow, the binding of related message can be realized through the related identities carried by the message and transmitted and received by certain physical devices. In the process of establishing a signaling messaged of non-first bearer for a PDN, the carried related bearer identities are used for referring to certain information.

Bearing identification processing method and equipment

Technical field

The present invention relates to wireless communication field, the technology of setting up of particularly carrying in the evolvement network.

Background technology

In order to guarantee the competitiveness of third generation partner program in following 10 years down to the time more of a specified duration (3rdGeneration Partnership Project is called for short " 3GPP ") system, the work of an access technology evolution is just carried out at the 3GPP organization internal.Particularly, in the 3GPP system, use group technology to need further to strengthen in order to strengthen the 3GPP system handles ability of the IP data service of growth fast.

As shown in Figure 1, the core net of evolvement network mainly comprises mobile management entity (MobilityManagement Entity is called for short " MME "), gateway (Serving Gateway) and three logic function modules of packet data network gateway (PDN Gateway).

MME is the mobile management module, be responsible for the mobile management of chain of command, comprise the management of user's context and mobile status, distributing user temporary identity sign, safety function etc., it is corresponding to current universal mobile telecommunications system (Universal Mobile Telecommunications System, abbreviation " UMTS ") the chain of command part of internal system service universal grouping wireless business supporting node (Serving GPRS Support Node is called for short " SGSN ").

Serving Gateway is the universal mobile telecommunications system grounding wireless access network (E-UTRAN) of evolution and the destination node of core network interface, point at any time, and any one UE only is connected to a Serving Gateway in the system.Serving Gateway mainly comprises following function: 1, the anchor point that switches between the evolution base station node eNodeB in the E-UTRAN; 2, the anchor point of switching between E-UTRAN and the universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio Access Network is called for short " UTRAN "); 3, Lawful Interception.

Below the flow process in the respective embodiments described above is carried out some supplementary notes.

Set up in the flow process in the carrying that UE initiates, UE sends to can carry in article one NAS message of MME with carrying and (for example: APN), carry the TI of a NAS message simultaneously sets up relevant information.Set up in the flow process EPS that MME has been distributed network side by ENB in follow-up carrying

Bearer identity sets up request message by carrying and sends to UE.

The message that the ENB that UE receives sends to it is not NAS message, in order to allow UE can identify which the bar message that receives from ENB is that article one NAS message that sends to MME with it is related, set up in the request message so send to the carrying that ENB and ENB send to UE, must carry that relevant sign is discerned this message and article one message is associated at MME.Can directly use the TI in the NAS message to be used as association identification, also can redefine a new parameter and identify.If the parameter of redefining need be carried this parameter in UE sends to article one NAS message of MME.

Association identification can be placed in the NAS message bag, sends to UE by ENB; Also can be directly send to UE as an IE of S1-AP and air protocol message.

If distribute EPS bearer identity by MME, set up in the flow process in the carrying that network side is initiated, PDN GW sends to carrying that Serving GW and Serving GW send to MME and sets up and do not carry EPS bearer identity in the message, because this moment, MME did not also distribute corresponding EPS beareridentity.Is follow-up carrying set up response message and how to be set up request message with carrying and bind? seen diverse ways from different aspects.If just do the binding of carrying aspect, can realize the binding of a pair of request and response message by the sequence number in the existing GTP message header.Do the binding on the bearing bed if desired, (for example: Corr-ID) realize asking binding with response message then need to introduce a new relevant parameter.

If distribute EPS bearer identity by PDN GW, set up in the flow process in the carrying that UE initiates, MME sends to carrying that Serving GW and Serving GW send to PDN GW and sets up and also do not carry EPS bearer identity in the request message, because this moment, PDN GW did not also distribute corresponding EPS bearer identity.So, also have the request message of two aspects and the binding issue of response message.

In addition, set up in the flow process in the carrying that UE initiates, if initiating carrying, UE trigger network side sets up flow process, sending to carrying that Serving GW and Serving GW send to PDN GW at MME sets up and must carry an association identification (for example: Corr-ID or EPS beareridentity etc.) in the request message, and carry identical association identification in follow-up PDN GW and message that Serving GW returns, this association identification is used for the binding between the different messages.In the message that follow-up PDN GW and ServingGW return, can not be again discern, because the sequence number of the sequence number of return messages and request message may be different with the sequence number of GTP message header.

When the carrying of initiating as UE is set up flow process and is used to set up dedicated bearer, need in corresponding signaling message, carry linked EPS bearer identity and linked TI.The carrying that network side is initiated is set up flow process and generally all is used to set up dedicated bearer, so need carry linked EPSbearer identity in corresponding signaling message.

In the respective embodiments described above, in the situation that relates to linked EPS bearer identity, linkedEPS bearer identity can be the EPS bearer identity of any carrying in each bar carrying (UE is to same PDN) of having set up.
