Abstract
The invention provides a control method of multi-bearing share AMBR, comprising the following steps: step one, a mobile management entity transmits AMBR bearing a share to a base station when establishing a first bearing sharing AMBR from a user terminal to a grouping data network; and step two, the mobile management entity transmits relative information of the other bearing and the bearing sharing AMBR to the base station when establishing another bearing sharing the AMBR. Thus, by using the invention, eNB is capable of controlling multi-bearing share AMBR by conveying AMBR share information via a S1-MME interface.
Description
Technical field
The present invention relates to moving communicating field, more specifically, relate to a kind of control method of sharing AMBR for multiple loads.
Background technology
Along with Wimax (World Interoperability for Microwave Access, global microwave access intercommunication) sudden emergence, 3-G (Generation Three mobile communication system) will keep its strong competitiveness at moving communicating field, must improve its network performance and reduce networking and operation cost.Therefore, 3GPP (3rd Generation Partnership Project, third generation partner program) standardization effort group is just being endeavoured research at present to PS Core (Packet Switch Core, the packet switch core net) and UTRAN (Universal MobileTelecommunication System Radio Access Network, the global system for mobile communications wireless access network) evolution, the problem of this research is called System Architecture Evolution (SystemArchitecture Evolution, be called for short SAE), purpose is to make the PS Core (being called for short E-PS Core) of evolution that higher transmission rate can be provided, shorter transmission delay, optimize grouping, and support E-UTRAN (Evolved UTRAN, the UTRAN of evolution), UTRAN, mobile management between the access network of WLAN (Wireless Local Area Network, WLAN (wireless local area network)) and other non-3GPP.The mobile communication system of this evolution just is called as EPS (Evolved Packet System), and its basic framework has wherein mainly comprised following network element as shown in Figure 1:
E-UTRAN (Evolved UTRAN) is made up of eNodeB (E-UTRAN NodeB), for user's access provides Radio Resource;
MME (Mobility Management Entity, mobile management entity) chain of command functional entity, the server of interim storaging user data, be in charge of and store the UE context (such as the UE/ user ID, mobility management states, user security parameters etc.), for the user distributes temporary mark, when UE quarters at this tracing area or this network is to be responsible for this user is carried out authentication, then handle all non-access layer informations between MME and the UE, triggering is in the paging of SAE, and wherein, the interface between eNodeB and the MME is a S1-MME interface;
HSS (Home Subscriber Server) is a home subscriber server, the permanent storage user contracting data, and authentication to the user is provided;
Serving GW (Gateway) is a gateway, and this gateway is a user entity, is responsible for the user face data route and handles, and termination is in the downlink data of the UE of idle state.SAE carrying (bearer) context of management and storage UE, such as IP bearer service parameter and network internal routing iinformation etc., it is the anchor point of 3GPP internal system user face, a user can only have a Serving GW a moment;
PDN (Packet Data Network) is a Packet Data Network, for the user provides professional network; And
PDN GW is a packet data network gateway, is responsible for the gateway function that UE inserts PDN, is the mobility anchor point of 3GPP and non-3GPP connecting system.
In mobile communication system, business is provided by carrying (bearer), different professional corresponding different bearer, thus satisfy different business needs, in order to satisfy professional requirement, bearer has a lot of attributes, comprises speed, priority etc.Bearer in the EPS system is defined as EPS bearer.
In the EPS system, AMBR (Aggregate Maximum Bit Rate) is the maximum rate that a plurality of bearer of same user share, the a plurality of EPS bearer that connect to same PDN (Packet DataNetworks) can share same AMBR, when other EPS bearer did not transmit data, each among these EPS bearer can use that this AMBR's is whole.AMBR has limited the summation of the speed that all EPSbearer of sharing this AMBR can provide.ENB will carry out the AMBR control of uplink and downlink.UE is the CAMEL-Subscription-Information of UE to the AMBR of different PDN, is stored among the HSS, when the UE access network, brings MME by HSS, can preserve these AMBR information at UE with MME during network keeps being connected always.When EPS Bearer set up, core net was according to the attribute of Bearer, decision Bearer whether with other Bearer sharing A MBR that is connected to same PDN.
A UE has a plurality of PDN and connects, all may have an AMBR to each PDN connection, so a UE has a plurality of AMBR, EPS bearer determines in core-network side the shared relationship of AMBR, the actual speed rate summation that eNB controls all EPS bearer is no more than AMBR, so need pass to eNB to the relation of EPS bearer sharing A MBR from the MME of network side by S1-MME interface, still not have effective method at present and can transmit AMBR at S1-MME interface and share control information.
Summary of the invention
In view of the above problems, the invention provides a kind of control method of sharing AMBR for multiple loads, transmit AMBR by S1-MME interface and share information, make eNB can realize control sharing AMBR for multiple loads.
The invention provides a kind of control method of sharing AMBR for multiple loads, may further comprise the steps: step 1, when setting up the carrying of first sharing A MBR from the user terminal to the Packet Data Network, mobile management entity is sent to the base station with the AMBR of bearing shared; And step 2, when setting up another carrying of sharing A MBR, mobile management entity is sent to the base station with another carrying and the related information of sharing the carrying of AMBR.
In step 2, also carry out following the processing: after obtaining related information, the carrying of the sharing A MBR that has set up is known in the base station.
State after the base station knows the carrying of sharing this AMBR of having set up at the place, preserve beared information by the base station, thereby obtain the beared information of all sharing A MBR that set up.
In addition, after the beared information of the sharing A MBR that all have been set up was known in the base station, the carrying of controlling newly-built carrying and all sharing A MBR is sharing A MBR together.
Wherein, the descending end points identifier of bearer path interface, the AMBR sign of the carrying of the bearing identification of the carrying of the sharing A MBR that set up of related information, the sharing A MBR that set up.
In the method according to the invention, also handle below the execution in step 1: mobile management entity is sent to the base station together with the value of AMBR sign and AMBR.
In addition, related information can also be the grouped data net address of sharing A MBR.In step 1, also carry out following the processing: mobile management entity is sent to the base station together with the value of grouped data net address and AMBR.
Other features and advantages of the present invention will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the present invention.Purpose of the present invention and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.
