Will now be described with reference to the drawings various aspects, wherein, be denoted by the same reference numerals identical key element in the whole text. In the following description, for illustrative purposes, numerous specific detail are described, in order to provide one or more aspects Thorough understanding.It will be apparent, however, that these aspects can be realized in the case of not using these specific detail.? In other example, in order to contribute to describing one or more aspect, known structure and equipment are shown in form of a block diagram.

Additionally, following, various aspects of the invention are described.It is readily apparent that the teaching of the application can use various ways Realize, and, any ad hoc structure disclosed in the present application and/or function are merely illustrative.Religion according to the application Show, it will be appreciated by those skilled in the art that aspect disclosed in the present application can realize independent of any other side, and Can combine in these aspects in various manners two or more.Such as, what use the application was illustrated is any amount of Aspect, it is possible to achieve a kind of device and/or a kind of method can be realized.Additionally, use removes that the application is illustrated Or other structure outside many aspects and/or function, or use and be different from one or more aspects that the application is illustrated Other structure and/or function, it is possible to achieve a kind of device and/or realize a kind of method.For example, to move being used for The central packet gateway of the data, services in dynamic communication connects and local packet gateway connect between carry out arbitration to wait be background, right Multiple method described herein, equipment, system and device are described.It will be apparent to a skilled person that class As technology can apply to other communication environment.

Owing to wireless network infrastructure and resource are improved in time, and owing to process and the user of mobile device connect Mouth ability becomes complicated all the more, and it is in the past logical only for personal computer and fixing circuit that user can use mobile device to perform The function that letter is available.This use is small-sized, portable equipment realizes high-quality voice communications, linking Internet, multimedia access With playback and amusement ability cause very it is desirable that consumer products.Via Radio Access Network (RAN), pass through Transmit the data that these mobile devices (such as, the subscriber equipment in mobile communications device [UE]) will be consumed in the air.These RAN may include that the infrastructure (such as, macro-cellular network deployment) that provider disposes；Infrastructure (its bag that user disposes Include local area network wireless router)；Or combinations thereof, such as, have that user disposes (it is referred to as home node-b in base station (HNB), enhancement mode HNB(HeNB), Femto cell etc.) the grand deployment of routine.

Cordless communication network can provide voice service, data, services or the two have concurrently.For voice service, traditional honeybee Nest core-network infrastructure contributes to the analog voice call between long-distance user.Additionally, the voice of internet protocol-based (VoIP) utilize the digital capabilities of packet data network to provide Digital Speech Communication.By via packet gateway (P-GW) by honeybee Nest network is coupled to numeral IP network, can formulate VoIP in cellular networks, wherein P-GW include for each network it Between the agreement of propagation data.The example of conventional P-GW is that gateway GPRS (general packet radio service) supports node or GGSN.

GGSN is Relatively centralized formula gateway, and it provides packet network (such as the Internet or X.25 network) and mobile radio communication Network (such as, drill for a long time by UMTS [GSM], Universal Mobile Telecommunications System [UMTS], third generation partner program Enter [3GPP LTE], WCDMA [WCDMA] etc.) between interface.Especially for the situation of the Internet, there is phase To less GGSN, and these GGSN are still configured to pass general packet radio service (GPRS) net going to multiple RAN Network provides the complicated entity of service for a large number of users.These GGSN serve as giving geographic area (generally, such as, for giving Fixed state, country, region alliance etc.) in the mobile station of UE to internet interface.

Use is stored in the packet-based data structure at GGSN, and (such as, [PDP is upper and lower for block data protocol context Literary composition], packet data network connect [PDN connection] etc.) promote the equipment mobility of activity data viability.One example Property data structure include PDP Context, this PDP Context storage IP address of UE, the current serving Node of this UE and and pin The out of Memory that the specific transactions tunnel setting up this UE or data stream are correlated with.Move around geographically along with UE and by not Same service node services, and this data structure is updated to reflect that current serving Node, so that proper data can It is routed to this UE.

Because conventional GGSN is relatively large centralized entities, so each government has established for enforcement Rule, wherein this rule follows the tracks of individual activity according to the packet connection at GGSN.Therefore, in applicable compass of competency, remove Beyond other function, GGSN is additionally configured to: storage UE situation of movement (such as, according to service node identifier)；And it is potential Ground record is about the information of Internet-related business.Additionally, GGSN is configurable to refuse the Internet by similar mechanism Services selection UE.

Because the centralized GGSN of relatively small number to process the major part (if not all) point of given geographic area Group related mobile communication business, so GGSN is extremely complex and expensive entity.Typical problem is also likely to be by this kind The centralized deployment of type causes.Such as, what hardware fault at GGSN or software fault can affect in broad area is a large amount of The packet network of user connects.Restart simply the software of this equipment may also be have very much destructive.Additionally, collection Chinese style framework produces may be by the network vulnerability of the utilizations such as data hacker, network piracy.Additionally, single service provider couple The ability that packet service at GGSN is customized is the most weak, thus needs to set for the diversified support basis realizing service Execute.

Recently, the proposal of the local disposition to P-GW has been initiated, in order to some reducing centralized P-GW framework are low Efficiency.Local GW can have and conventional function similar for P-GW, but includes relatively inexpensive hardware, and wherein this hardware causes whole The cost-efficient duplication of these entities in individual RAN.Additionally, the conventional P-GW phase being customized with service provider Ratio, can be customized local GW with higher degree.Local GW can be linked to the Internet or other packet network, and to One group of RAN base station provides packet service, and wherein this group RAN base station includes: enode b that provider disposes (or other user The RAN base station disposed)；Or HeNB(that user disposes etc.) base station.The quantity of the base station that local GW is serviced and these The business load of base station and geographical or topological overlay area can be different and change (the most local GW in the application with entity Cover umbrella).

In the case of the conventional GW and local GW of the packet service in mobile communication coexist, it is possible to achieve these P- Arbitration between GW.In one aspect of the invention, this arbitration mechanism is referred to as selected internet protocol traffic unloading , and this arbitration mechanism refers to from central authorities P-GW, Packet Service is unloaded to local GW (SIPTO).For these aspects, in Arbitration between centre GW and local GW can realize based on UE one by one, or can be with access point network one by one (APN) Based on realize, or can realize with the combination of above-mentioned two ways.Such as the application institute in greater detail, Ke Yijian Vertical various standards, in order to determine whether to connect specific packet network to be unloaded to local GW from central authorities P-GW.This example bag Include UE reservation state, government's restriction, rate etc. between APN ability, network.

Referring now to accompanying drawing, Fig. 1 shows the exemplary nothing of the deployment of the SIPTO for realizing local GW or local GW The block diagram of wire system 100.Specifically, wireless system 100 includes that IP operation unloading selects device 102, the unloading choosing of this IP operation Select device 102 to be configured to receive, from mobile communications network, the request 110 that packet network is connected.In response to request 110, IP operation Whether unloading selects device 102 to be configured to determine whether to service request 110 at central authorities P-GW, or can will ask 110 are asked to be unloaded to local GW(in the case of available).Alternatively, once having carried out above-mentioned determining, IP operation unloading selects dress Put 102 to send packet network to suitable P-GW and set up order 118.

IP operation unloading selects device 102 to may include that memorizer 104, and it contributes to unloading IP operation for storage Instruction to local packet network gateway；And data processor 106, it performs the module for realizing these instructions.Specifically For, these modules may include that receiver module 108, its identify to packet network (such as, the IP network of such as the Internet) The request of connection, and obtain the subscription information collection for the UE initiating this request 110.This subscription information can be from serving The mobile network of this UE is (such as, from attaching position register [HLR], Visitor Location Register [VLR], home subscriber server [HSS] etc.) in obtain, or can from memorizer 104(such as, in response to packet connect previous Request 110 and The acquisition of subscription information, in the case of being stored in subscription information in memorizer 104) etc. in obtain, or can from they Appropriately combined middle acquisition.

Receiver module 108 will be transmitted to parsing module 112, wherein, this parsing module about the UE subscription information of request 110 112 analyze this subscription information, and determine whether that permitting this UE uses local GW service.This determines to be based at least partially on deposits Storage SIPTO rule set 114 in memorizer 104.In an example, SIPTO rule 114 can be specified and is used to determine whether Permit UE and use the UE specific criteria of local GW service.The example of UE specific criteria may include that whether the reservation of this UE is supported SIPTO；The state of this reservation；The state (it stores into a part for UE subscription data) of SIPTO Enable/Disable mark, etc.. In another example, SIPTO rule 114 can be specified and is used to determine whether that permitting UE uses the APN of local GW service specific Standard.The example of APN specific criteria may include that the SIPTO of APN that store into a part for UE subscription data, given allow/ The state of prohibitory sign；Service quality (QoS) ability (for example, with reference to hereafter) of the APN according to request 110 identification, etc..? At least one aspect of the present invention, permitting can be based on UE specific criteria and the combination of APN specific criteria.

If disapproving UE to use local GW service, then IP operation discharge mechanism 102 can send packet network alternatively Set up order 118, and this order is alternatively sent to conventional P-GW(such as, GGSN).On the other hand, if permitting UE and using Local GW service, then data processor 106 can perform to identify the referrer module 116 of local GW, and wherein, this this locality GW is used for building Stand the connection with IP network, and this this locality GW is associated with providing the base station of mobile network service to this UE.

Referrer module 116 can identify this this locality GW according to one or more in number of mechanisms.Such as, referrer module 116 can use the data list that each the local GW in being disposed by local GW is associated with each mobile network base station collection, and And cross reference can be carried out to the base station of UE offer mobile network service and this locality being associated with this base station by this data list GW.In yet another aspect, referrer module 116 can send inquiry (not shown) to base station, and wherein this inquiry is explicitly or hidden The identifier (such as, IP address) of the local GW that the request of formula ground is associated.In other side, referrer module 116 can so that Name server can return geographically or in topology close to the form of local GW of this base station, performs name server (DNS) inquiry.Such as, in the case of at least one, this form can include the identifier of UE or the identifier of base station.

It should be appreciated that IP operation unloading selection device can be realized each physical locations in a communication network 102.In an example, IP operation unloads the part that selection device 102 can be implemented as the service node of packet-based core networks (such as, of the Serving GPRS Support Node [SGSN] in GSM/EDGE [GSM evolution enhanced data rates] wireless system Point, the Mobility Management Entity [MME] in 3GPP LTE wireless system or the similar solid in other wireless system).Separately In one example, IP operation unloading choosing can be realized by the gateway between the network of mobile service provider and mobile core network Select device 102.As another example, IP operation unloading selects device 102 to can be implemented at P-GW, and no matter this P-GW is this The conventional P-GW of ground GW the most such as GGSN.At at least one aspect of the present invention, can be in multiple aforementioned or similar positions On realize in a distributed fashion IP operation unloading select device 102.

Such as, by providing the arbitration between different P-GW, wireless system 100 can aid in the conventional P-GW of realization and Business between the deployment of local GW loads.Such as, this is for following the government requiring to carry out honeycomb tracking at central authorities GGSN It is important for regulation.Therefore, if UE carries out this tracking, then wireless system can set up packet even at GGSN Connect, and other UE not affected by this requirement alternatively can be routed to local GW.Additionally, by the local GW of customization, different Service provider particular packet network service can be provided, in order to distinguish their own and other service provider；It is fixed to meet The hardware of local GW or the UE of software requirement of system can be routed to this this locality GW, and the UE being unsatisfactory for these requirements can be by It is routed to other places, etc..Can also obtain other interests and use according to the arbitration between different P-GW, this is for this area It is apparent from for those of ordinary skill.These interests and use are considered the part of the present invention.

Fig. 2 show according to a particular aspect of the invention, be adapted for carrying out the SIPTO for mobile communication exemplary The block diagram of network environment 100.Network environment 100 can include UE 202, and this UE 202 is via wireless link and Serving cell 204 It is coupled communicatedly.If being arranged to IP network service, then UE 202 can send request 206, to set up with the most mutual The connection of the IP network of networking 218.At Serving cell 204, receive request 206, and this request 206 is forwarded to unloading choosing Select device 208.The example of request 206 can include activating packet data protocol (PDP) context request, packet data network (PDN) connection request or be suitable for the similar request of various Radio Network System.In one aspect of the invention, unloading choosing Select device 208 and can be substantially similar to the IP operation unloading selection device 102 of above-mentioned Fig. 1, but the present invention is not limited to the party Face.
