Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

The embodiment of the invention provides method for releasing that a kind of terminal carries and relevant device, system, and the carrying that can when the user switches to non-CSG sub-district from the CSG sub-district, carry out the terminal discharges, and avoids the user to pay more rate, promotes user experience.Below be elaborated respectively.

See also Fig. 1, the schematic flow sheet of the method for releasing that Fig. 1 carries for a kind of terminal that the embodiment of the invention provides.As shown in Figure 1, this method can may further comprise the steps:

101, (User Equipment, the request message that UE) sends through the base station wherein, carry the cell information of first sub-district that belongs to when this UE initiates this request message to receiving terminal in this request message;

In the embodiment of the invention, above-mentioned request message can be a business request information, also can be that (embodiment of the invention does not limit public data network for Public Data Network, PDN) connection request message.

In the embodiment of the invention, UE can be mobile phone, palmtop PC and other communication apparatus.

In the embodiment of the invention, the base station can be macro base station, also can be that (Home NodeB HNB), can also be that (Home Evolved NodeB, HeNB), the embodiment of the invention does not limit family's evolution base station to Home eNodeB.

In PLMN; UE can (be called first sub-district) and initiate business request information or PDN connection request message in some sub-districts of PLMN, wherein, this request message can be sent to mobile management entity (the Mobility Management Entity of network side through the base station that covers this sub-district; MME); Carried out bearing modification according to the request message of UE or carried flow process such as foundations by MME, set up required wireless and core net to carry, realization UE is connected with the business of network side.Follow-up, UE will keep as much as possible and should business connect in moving process, promptly keep this professional continuity as much as possible.

102, the cell information of above-mentioned first sub-district of storage; The cell information of this first sub-district comprises the sub-district ID and the CSG ID of first sub-district, perhaps only comprises the sub-district ID of first sub-district;

Wherein, MME is after receiving the request message of UE through the base station transmission, and MME can store the cell information of first sub-district that belongs to when the UE that carries in this request message initiates this request message.

For instance; When if first sub-district that UE belongs to when initiating business request information is the CSG sub-district; The base station that then covers first sub-district can be added into the sub-district ID and the CSG ID of first sub-district in this business request information, and is sent to MME after the business request information that receives the UE initiation.

Again for instance; When if first sub-district that UE belongs to when initiating the PDN request message is non-CSG sub-district (like macrocell); Macro base station or the Home eNodeB that then covers first sub-district is after receiving the PDN request message that UE initiates; Can the sub-district ID of first sub-district be added in this PDN request message, and be sent to MME.

In the embodiment of the invention, the sub-district ID of first sub-district can be the Cell Global Identification of sub-district (Cell Global Identifier, CGI).

103, receive the handoff request message that send the base station, wherein, carry the cell information of second sub-district that above-mentioned UE switches in this handoff request message;

In PLMN; UE can be moved; And in moving process, can ceaselessly measure the signal of its peripheral cell; And measurement report reported to the base station that covers sub-district, the current place of UE, determine second sub-district that UE switches to by the base station that covers sub-district, the current place of UE, and whether initiate cell switch process UE according to the switch decision criterion decision of self setting.

When the cell switch process to UE is initiated according to the switch decision criterion decision of self setting in the base station that covers sub-district, the current place of UE; The cell information that covers second sub-district that the base station of sub-district, the current place of UE can switch to UE is added in the handoff request message, and sends to MME.

Wherein, For the base station that covers sub-district, the current place of UE; It is after receiving the measurement report that UE reports, and it is strong and weak to arrive the signal of UE according to each sub-district in the measurement report, determines second sub-district that the strongest sub-district of signal that arrives UE switches to as UE.

For instance, the signal strength signal intensity of second sub-district arrival UE can be judged more than or equal to predetermined threshold value (being the switch decision criterion) in the base station of covering sub-district, the current place of UE whether, if then the cell switch process to UE is initiated in decision.

In the embodiment of the invention,,, also might be different sub-districts so first sub-district and sub-district, the current place of UE that UE belonged to when initiating business request information or PDN connection request message might be same sub-districts because UE can be moved; The base station that promptly receives the request message that UE initiates possibly be same base station with receiving the UE reporting measurement reports and sending handoff request message to the base station of MME, also possibly be different base stations.

104, the cell information of storage second sub-district; The cell information of this second sub-district comprises the sub-district ID and the CSG ID of second sub-district, perhaps only comprises the sub-district ID of second sub-district;

Wherein, MME is after receiving the handoff request message of sending base station (promptly covering the macro base station or the Home eNodeB of q sub-district, the current place of UE), and MME can store the cell information of second sub-district that the UE that carries in this handoff request message switches to.

For instance, if second sub-district that UE switches to is the CSG sub-district, then the cell information of second sub-district can comprise sub-district ID and the CSG ID with second sub-district.

Again for instance, if second sub-district that UE switches to is non-CSG sub-district (like macrocell), then the cell information of second sub-district can only comprise the sub-district ID with second sub-district.

In the embodiment of the invention, the sub-district ID of second sub-district can be the CGI of sub-district.

105, if above-mentioned first sub-district is the CSG sub-district, and above-mentioned second sub-district is non-CSG sub-district, then discharges the carrying of UE.

In the embodiment of the invention; MME has stored after the cell information of cell information and second sub-district of first sub-district; If determine sub-district ID and CSGID that the cell information of first sub-district comprises first sub-district; And the cell information of second sub-district only comprises the sub-district ID of second sub-district, and first sub-district that belongs to when the UE initial request messages then is described is the CSG sub-district, and second sub-district that UE switches to is non-CSG sub-district.Because rate or free services that the user can enjoy privileges when in the CSG sub-district, carrying out business exchange, and the user need pay more rate when in non-CSG sub-district, carrying out business exchange.Pay more rate for fear of the user, MME is the CSG sub-district determining first sub-district, and second sub-district is after the non-CSG sub-district, and MME can discharge the carrying of UE, prevents to cause the user to pay more rate when UE from switching to non-CSG sub-district from the CSG sub-district.

Wherein, In first sub-district is that the CSG sub-district and second sub-district are the CSG sub-district, and perhaps first sub-district is that the non-CSG sub-district and second sub-district are non-CSG sub-district, and perhaps first sub-district is non-CSG sub-district; And second sub-district is the situation of CSG sub-district, and MME can not discharge the carrying of UE.Because, when UE switches to the CSG sub-district from the CSG sub-district, perhaps when non-CSG sub-district switches to non-CSG sub-district; The rate that the user need pay do not increase; The rate that need pay of user are fewer in other words, can not influence user experience, then can not discharge the carrying of UE; And switch to the CSG sub-district from non-CSG sub-district as UE, the rate that the user need pay still less, user experience is higher, also need not to discharge the carrying of UE.

As an optional execution mode; MME is the CSG sub-district determining first sub-district, and second sub-district is after the non-CSG sub-district, and MME can confirm whether the UE corresponding strategy of storing in advance is to allow to carry to discharge; Discharge if allow to carry, then discharge the carrying of UE; Otherwise, the carrying that then keeps UE.

As another optional execution mode, can carry the indication information that UE sends in the business request information that UE initiates, this indication information is used to indicate UE whether to allow to carry release.Correspondingly, MME is the CSG sub-district determining first sub-district, and second sub-district is after the non-CSG sub-district, and MME can confirm whether UE allows to carry according to this indication information and discharge, and discharges if allow to carry, and then discharges the carrying of UE; Otherwise, the carrying that keeps UE.

As another optional execution mode; MME is the CSG sub-district determining first sub-district, and second sub-district is after the non-CSG sub-district, and MME can discharge an any public data network (Public Data Network of UE; PDN) any in the connection is carried or all carryings; Carrying during all PDN that perhaps discharge UE connect perhaps discharges specific transactions or particular access point name (Access Point Name, the business under APN) of UE.

In the embodiment of the invention, MME is the CSG sub-district determining first sub-district, and second sub-district is after the non-CSG sub-district, and MME also can send a notification message to UE, initiatively discharges its carrying by UE.Equally, UE also can initiatively discharge any carrying or all carryings in any PDN connection, perhaps discharges the carrying in all PDN connections, perhaps discharges the business under specific transactions or the specific APN.

As another optional execution mode; MME is the CSG sub-district that UE is authorized to insert determining first sub-district, and second sub-district is when being the CSG sub-district of the uncommitted access of UE, and MME can discharge the carrying of UE; Perhaps MME also can send a notification message to UE, initiatively discharges its carrying by UE.Because; If UE inserts the CSG sub-district of uncommitted access by force; Often need pay more rate, influence user experience widely, so MME is the CSG sub-district that UE is authorized to insert determining first sub-district; And second sub-district can discharge the carrying of UE when being the CSG sub-district of the uncommitted access of UE, and perhaps MME also can send a notification message to UE and initiatively discharge its carrying.

In the embodiment of the invention, the cell information of first sub-district that MME belongs in the time of can storing the UE initial request messages, the cell information of this first sub-district comprise the sub-district ID and the CSG ID of first sub-district, perhaps only comprise the sub-district ID of first sub-district; And the cell information of second sub-district that switches to of the UE that carries in the handoff request message of sending of storage base station, the cell information of this second sub-district comprises the sub-district ID and the CSG ID of second sub-district, perhaps only comprises the sub-district ID of second sub-district; MME is the CSG sub-district determining first sub-district, and second sub-district is after the non-CSG sub-district, is discharged the carrying of UE by MME.The embodiment of the invention can be carried out UE when the user switches to non-CSG sub-district from the CSG sub-district carrying discharges, and pays more rate to avoid the user, promotes user experience.

In order to understand the method for releasing that carry at terminal that the embodiment of the invention provides better, describe below in conjunction with specific embodiment.Before describing specific embodiment provided by the invention, earlier the network element that relates in the specific embodiment is described.

Wherein, the base station is mainly used in the transmitting-receiving of being responsible for wireless signal, through air interface and UE contact.
