Specific embodiment

Under normal circumstances, the UE in Idle state will initiate RRC connection establishment process after receiving paging message to respond paging message, and UE can carry out data transmission after entering connected state with network；And if the UE in connected state receives paging message, can ignore the paging message, will not initiate RRC connection establishment process.But above-mentioned UE processing paging message may cause and lose words, details are as follows:

A kind for the treatment of process for the paging message that UE is sent for base station is as shown in Figure 1:

MME sends paging message (Paging) to UE by base station, after UE receives the paging message, RRC connection request (RRC Connection Request) message is sent to base station, RRC connection is established in request, after base station receives the RRC connection request message, RRC connection, which is sent, to UE establishes (RRC Connection Setup) message, the relevant parameter for the RRC connection for notifying UE to establish, UE is configured according to the relevant parameter for establishing RRC connection that RRC connection is established in message, configuration sends RRC connection to base station after completing and establishes completion (RRC Conneciton Setup Complete) message, complete RRC establishment of connection.

After base station receives the RRC connection setup complete message, initial UE message (Initial UE Message) is sent to MME, after MME receives the initial UE message, initial context is sent to base station and establishes request (Initial Context Setup Request) message, and the context of the UE is established in request.Base station receives after the initial context establishes request message; RRC safe mode command (RRC Security Mode Command) message can be sent to UE; carry the relevant parameter of encryption and integrity protection; after UE obtains the relevant parameter of encryption and integrity protection, replys RRC safe mode and complete (RRC Security Mode Complete).

Next, base station can send RRC connection reconfiguration to UE and set (RRC Connection Reconfiguration), UE replys RRC connection reconfiguration and sets completion (RRC Connection Reconfiguration), to complete the reconfiguration course of RRC connection.After the completion of RRC connection reconfiguration is set, base station replys initial context to MME and establishes completion (Initial Context Setup Complete) message, completes the foundation of the context of the UE.

At this point, UE enters connected state after the RRC Connection Setup message for receiving base station transmission, If the UE in connected state receives paging message, the message can be ignored without performing corresponding processing.

Another UE is as shown in Figure 2 for the treatment process for the paging message that base station is sent:

If the UE in connected state is transmitted without data for a long time, inactivity timer (Inactivity Timer) time-out of base station side, then base station sends RRC Connection Release (RRC Connection Release) message so that UE discharges RRC connection and enters Idle state to UE.But the RRC connection release message of base station transmission may not be received always due to poor signal quality, UE, this results in network to think that UE enters Idle state, but the side UE is still in connected state.When UE has downlink data arrival, it is believed that UE is in the network-triggered paging of Idle state, and base station is after eating dishes without rice or wine to send paging message to UE, by the regulation of existing protocol, UE can ignore the paging without initiating the connection establishment process, eventually lead to network side paging less than the UE, cause to lose words.

The present invention provides a kind of paging equipment and method, to realize that UE correctly handles the paging message of base station transmission, to ensure and network normal communication.

In the following, being described in detail in conjunction with attached drawing.

Fig. 3 is the structural schematic diagram for the wireless communication system that one embodiment provides.As shown in Figure 3, the wireless communication system includes: terminal device 301, access network equipment 302 and equipment of the core network 303, wherein terminal device 301 can be connect by being wirelessly connected with access network equipment 302, and access network equipment 302 can be connected by wire or wireless to be connect with equipment of the core network 303.

Currently, base station can send paging message to UE in following a variety of situations by taking LTE system as an example:

1, after the paging message of paging UE for receiving MME transmission, paging message is sent to the UE in Idle state on eating dishes without rice or wine, the identification information of the UE is carried in paging message, such as: system framework evolution (System Architecture Evolution, SAE Temporary Mobile Station Identifier (SAE Temporary Mobile Station Identifier,) or international mobile subscriber identity (International Mobile Subscriber Identification Number, IMSI) S-TMSI；

2, UE changing system information of the notice in Idle state or connected state.

In case 1, the identification information of the UE can be carried in paging message.Therefore, UE is on eating dishes without rice or wine After receiving paging message, however, it is determined that the identification information of itself is carried in paging message, then can determine the paging message be intended for itself for page be in Idle state UE paging message.

But as previously mentioned, according to the processing in current LTE system, UE can abandon the paging message if UE will be considered that itself still in connected state not receiving RRC connection release message, UE before.

In wireless communication system shown in Fig. 3, terminal device 301 is receiving the paging message for call terminal equipment 301, and when the mark of the paging message carried terminal equipment 301, even if itself, which is determined, is in connected state, it can also respond the paging message and initiate RRC connection establishment process.

The communication standard of wireless communication system shown in Fig. 3 includes but is not limited to: global system for mobile communications (Global System of Mobile communication, GSM), CDMA (Code Division Multiple Access, CDMA) IS-95, CDMA (Code Division Multiple Access, CDMA) 2000, TD SDMA (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), time division duplex-long term evolution (Time Division Duplexing-Long Term Evolution, TDD LTE), frequency division duplex-long term evolution (Frequency Division Duplexing-Long Term Evolution, FDD LTE), long term evolution-enhancing (Long Term Evolution-Advanced, LTE-advanced), personal handyphone system (Personal Handy-phone System PHS), Wireless Fidelity (Wireless Fidelity as defined in 802.11 serial protocols, WiFi), worldwide interoperability for microwave accesses (Worldwide Interoperability for Microwave Access,), and the various wireless communication systems of the following evolution WiMAX.

It is inconsistent simply by the presence of terminal device and network state, terminal device determines that itself is in connected state, and network determines that terminal device is in Idle state, and terminal device is caused to ignore the paging message for paging the terminal device for being in Idle state, wireless communication system shown in Fig. 3 can be used to avoid words are lost.

Wherein, network can refer to access network equipment 302 here, also can refer to access network equipment 302 and equipment of the core network 303, or may also comprise the network equipment including access network equipment 302 and equipment of the core network 303 and other equipment.

Wherein, terminal device 301 can be wireless terminal, and wireless terminal can be directed to user and provide the equipment of voice and/or data connectivity, has the handheld device of wireless connecting function or is connected to wireless Other processing equipments of modem.Wireless terminal can through wireless access network (such as, RAN, Radio Access Network) it is communicated with one or more core nets, wireless terminal can be mobile terminal, such as mobile phone (or be " honeycomb " phone) and the computer with mobile terminal, for example, it may be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they exchange language and/or data with wireless access network.Such as, personal communication service (PCS, Personal Communication Service) phone, wireless phone, Session initiation Protocol (SIP) phone, wireless local loop (WLL, Wireless Local Loop) it stands, the equipment such as personal digital assistant (PDA, Personal Digital Assistant).Wireless terminal is referred to as subscriber unit (Subscriber Unit), subscriber station (Subscriber Station), movement station (Mobile Station), mobile station (Mobile), distant station (Remote Station), access point (Access Point), remote terminal (Remote Terminal), access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent), user equipment (User Device), or user equipment (User Equipment).

Access network equipment 302 may include base station, or for the wireless resource management equipment of control base station, or including base station and for the wireless resource management equipment of control base station；Wherein base station can be macro station or small station, such as: cell (small cell), Microcell (pico cell) etc., base station can also be Home eNodeB, such as: home node-b (Home NodeB, HNB), family's evolution node B (Home eNodeB, HeNB) etc., base station may also comprise relay node (relay) etc..

Equipment of the core network 303 may include the equipment of the core network for carrying out mobile management, such as: mobile switching centre (Mobile Switching Center,) or mobile management entity (Mobility Management Entity, MME) etc. MSC.

Such as: it can be evolution node B (evolved NodeB, eNodeB) for the LTE systems such as TDD LTE, FDD LTE or LTE-A access network equipment 302, terminal device 301 can be UE, and equipment of the core network 303 can be MME；For TD-SCDMA system or WCDMA system, access network equipment 302 can include: node B (NodeB) and/or radio network controller (Radio Network Controller, RNC), terminal device 301 can be UE, and equipment of the core network 303 can be MSC；For gsm system, access network equipment 302 may include base transceiver station (Base Transceiver Station, BTS) and/or base station controller (Base Station Controller, BSC), terminal 102 can be mobile station (Mobile Station MS), equipment of the core network 303 can be MSC.

Such as: for LTE system, the network architecture of wireless communication system shown in Fig. 3 can be as shown in Figure 5.Wherein, terminal device 301 is UE, access network equipment 302 is base station, equipment of the core network 303 is MME, and the interface between UE and base station is Uu mouthfuls, also referred to as " eating dishes without rice or wine ", " air interface ", " wireless interface " etc., interface between base station and MME is S1-MME mouthfuls, interface between base station and gateway (Serving-GateWay, S-GW) is S1-U mouthfuls, and the interface between MME and S-GW is S11 mouthfuls.

Using process shown in Fig. 4, the problem of terminal device 301 enters Idle state, can not establish connection with network may cause.Below with reference to Fig. 6 A, it is illustrated by taking LTE system as an example.

In Fig. 6 A, dotted line represents paging access process, 301 active access process of solid line GC group connector equipment.Access network equipment 302 (base station) will not eat dishes without rice or wine to page corresponding terminal device 301 (UE) immediately after receiving the paging message that equipment of the core network 303 (MME) is sent, but paging message is sent to UE until the paging occasion of the UE arrives, so base station may be in the RRC connection establishment process that UE is actively initiated, after such as receiving RRC Connection Setup Complete message, paging message is sent before sending RRC Security Mode Command message to UE, UE is that the paging message that response receives initiates RRC connection establishment process again, base station sends Initial UE Message message to MME again at S1-MME mouthfuls, MME Identify that the Initial UE message message received twice is the same UE triggering according to the UE mark S-TMSI carried in Initial UE Message message, therefore MME thinks wrong, and then the release command of UE context is sent to base station, it is required that the UE context that release had previously been established, after base station receives the order, determine that context establishes failure, failure of establishing initial context (Initial Context Setup Fail) message is returned to MME, and RRC connection release message (the RRC Connection Release message of solid line in corresponding diagram 6A) is sent to UE, and there is no because being received again by Initial UE by MME Message message (the Initial UE Message message of dotted line in Fig. 6 A) and request establish new S1 connection, therefore, the Article 2 Initial UE Message message (the Initial UE Message message of dotted line in Fig. 6 A) in Fig. 6 A sent corresponding to base station, base station waits preset duration, but it is not received by the response message of MME before the preset duration terminates, then sends RRC connection release message to UE again.

It can be seen that from Fig. 6 A, if base station is in the RRC connection establishment process that UE is initiated, or RRC connection establishes after completing and sends paging message to UE, it may cause UE shown in Fig. 6 A to eventually enter into Idle state and can not carry out data transmission with network, therefore, further, the UE of connected state by the kinds of schemes including one~optinal plan of optinal plan four, can be avoided to generate concurrent situation when responding paging message.

For the generation for avoiding above situation, in optinal plan one, start a timer at terminal device 301, ignore the paging if receiving paging message before timer is in timeout mode if terminal device 301, if terminal device 301 receives paging message after timer is in timeout mode and initiates RRC connection establishment process again；

In optinal plan two and optinal plan three, access network equipment 302 is according to two message successively received --- and the relevant information carried in paging message and RRC connection request message judge accordingly to deciding whether eating dishes without rice or wine to send paging message；

In optinal plan four, equipment of the core network 303 carries out corresponding processing for situation shown in Fig. 6 A occurred: MME be received again by discharged after Initial UE Message message on the interface between equipment of the core network 303 and access network equipment 302 previously established for the S1 connection re-established in the S1 connection of terminal device 301 and the interface between equipment of the core network 303 and access network equipment 302 for terminal device 301.

Four kinds of optinal plans are described in detail below.

[optinal plan one]

Fig. 7 is the flow chart of optinal plan one.As shown in fig. 7, the process includes the following steps:

S701: terminal device 301 initiates first time RRC connection establishment process to access network equipment 302, for example initiates first time RRC connection establishment process by sending RRC connection request message；

S702: terminal device 301 is in the first time RRC connection establishment process of initiation or RRC connection establishes and starts timer after the completion；

S703: terminal device 301 receives the paging message that access network equipment 302 is sent, the mark of carried terminal equipment 301 in the paging message；

If timer is in timeout mode when receiving paging message, terminal device 301 executes step S704: second of RRC connection establishment process is initiated in response to received paging message；If timer is in and has not timed out state, terminal device 301 ignores paging message.

Terminal device 301 ignores the paging message, the RRC connection that above-mentioned first time RRC connection procedure can be maintained to establish.

In optinal plan one, terminal device 301 can be in first time RRC connection establishment process, or after the completion of RRC connection is established, start a timer, so that terminal device 301 is before timer is in timeout mode according to the paging message received or timer is in timeout mode and decides whether to handle the paging message later.

Wherein, the timer that terminal device 301 starts can exclude situation shown in Fig. 6 A above-mentioned.If terminal device 301 receives paging message before timer is in timeout mode, terminal device 301 can ignore the paging message without will do it respective handling, if terminal device 301 receives paging message after timer is in timeout mode, terminal device 301 can initiate second of RRC connection establishment process to respond paging.

Optionally, terminal device 301 can start timer or terminal device 301 when sending RRC connection request and start timer when receiving RRC connection and establishing message, then alternatively, terminal device 301 starts timer when sending RRC connection setup complete message.

Such as: according to the regulation of current LTE system related protocol, terminal device 301 enters connected state after receiving RRC connection and establishing message, therefore can pay the utmost attention to receive when message is established in RRC connection in terminal device 301 and start timer.

The duration of the timer can for 1s, 2s, 2.5s, 3s ..., 10s, 10.5s etc..Optionally, the settable minimum value of the duration of the timer is paging cycle.

The timer terminal device is initiated for identification RRC connection establishment process and the concurrent scene of paging, such as: concurrent scene shown in Fig. 6 A, under the scene, RRC connection establishment process and the MME that terminal device is actively initiated send paging message and occur within the similar time.As shown in Figure 6B, access network equipment 302 starts to terminate in this period to access network equipment 302 to the transmission of equipment of the core network 303 initial UE message in the paging occasion of call terminal equipment 301, if equipment of the core network 303 sends the paging message of call terminal equipment 301 to access network equipment 302, above-mentioned concurrent scene will lead to.

The setting of the duration of the timer is contemplated that following factor: not can avoid the generation of situation shown in above-mentioned Fig. 6 A if the duration of timer is too short, if the duration of timer is too long terminal device 301 may miss page messages receiving time and lose words again, therefore when the duration of timer is arranged, it is contemplated that connected state can be reentered after so that terminal device 301 is initiated RRC connection establishment process again and carried out data transmission with network.Such as:

1, the duration of timer, such as 10s are provided in the protocol；

2, the duration of timer is calculated according to certain formula, such as: the paging cycle of the broadcast terminal equipment 301 in system message of access network equipment 302, terminal device 301 can determine the duration of timer according to paging cycle, as the duration of timer may be configured as: 2 times of paging cycle, this 2 times merely illustrative, however not excluded that other determine the mode of the duration of timer according to paging cycle；

3, it is determined by access network equipment 302 and notifies terminal device 301.Such as: terminal device 301 starts timer when receiving RRC connection and establishing message, then access network equipment 302 can be established in message in the RRC connection sent to terminal device 301, carry the information for being used to indicate the duration of timer, terminal device 301 receives after RRC connection establishes message, the information of the duration for being used to indicate timer is obtained from the message, and the duration of timer is determined according to the information, and such as: access network equipment 302 can determine the when a length of 10s of the timer.

Optionally, access network equipment 302 can determine the duration of timer according to paging cycle.

In Fig. 8 by taking terminal device 301 receives and starts timer when message is established in RRC connection as an example, a kind of achievable process of optinal plan one is shown.

In Fig. 8, terminal device 301 initiates RRC connection establishment process by sending RRC connection request message, and terminal device 301, when message is established in the RRC connection for receiving the transmission of access network equipment 302, starts timer in RRC connection establishment process.Terminal device 301 receives the paging message that access network equipment 302 is sent and then ignores the paging message if the timer of starting has not timed out when receiving the paging message；If receive the paging message, timer has been terminated, then responds the paging message and re-initiate RRC connection establishment process.

By using optinal plan one, terminal device 301 starts a timer, eventually enters into Idle state to avoid UE shown in Fig. 6 A and the situation that can not carry out data transmission with network, and can avoid losing words.Mesh In preceding LTE system, paging message is only received when terminal device 301 is in Idle state can just establish connection with network, and the terminal device 301 in connected state can ignore paging message, this, which may cause, loses words.Compared with the processing mode of current LTE system, optinal plan one can either solve the problems, such as to lose words, also can be avoided RRC connection establishment process and the concurrent situation of paging.

In optinal plan one, by the way that timer is arranged in 301 side of terminal device, the concurrent scene of the paging message that the RRC connection establishment process and network that identification terminal equipment is initiated are sent, to avoid the problem that UE shown in Fig. 6 A eventually enters into Idle state and can not carry out data transmission with network.

Furthermore, it includes: terminal device 301 since sending RRC connection request that another kind, which avoids the optinal plan of situation shown in Fig. 6 A by the processing of 301 side of terminal device, to Signaling Radio Bearer (Signalling Radio Bearer, SRB) 2 or Data Radio Bearer (Data Radio Bearer, DRB it) establishes and completes in this period, if receiving the paging message for paging Idle state terminal device, ignore the paging message received；Optionally, after the completion of SRB2 and DRB is established, if receiving the paging message for paging Idle state UE, it can handle the paging message received, for example initiate RRC connection establishment process in response to the paging message.

[optinal plan two]

Fig. 9 is the flow chart of optinal plan two.As shown in figure 9, the process includes the following steps:

S901: the RRC connection request message that 302 receiving terminal apparatus 301 of access network equipment is sent, RRC connection request message includes the mark of terminal device 301；

S902: whether access network equipment 302 has been received by the paging message for terminal device 301 of the transmission of equipment of the core network 303 based on the mark judgement of terminal device 301 before；If access network equipment 302 has been received by the paging message for terminal device 301 of the transmission of equipment of the core network 303 before determining, S903 is thened follow the steps；

S903: access network equipment 302 judges whether according to paging message call terminal equipment 301；If access network equipment 302 determines not yet according to paging message call terminal equipment 301, the paging message is abandoned.

In each embodiment of the present invention, discarding paging message can be understood as access network equipment 302 and abandon call terminal equipment 301, repeat no more below.

In the following, by taking access network equipment 302 has been received by the paging message for terminal device 301 of the transmission of equipment of the core network 303 before receiving RRC connection request as an example, being illustrated with reference to Figure 10.

As shown in Figure 10, access network equipment 302 is firstly received the paging message of the transmission of equipment of the core network 303, includes the mark S-TMSI for the terminal device 301 being paged in the paging message.

Access network equipment 302 can safeguard the S-TMSI after receiving the paging message.Access network equipment 302 configures radio frames and subframe used in call terminal equipment 301, that is, determines paging occasion, and access network equipment 302 prepares to send paging message at determining paging occasion with call terminal equipment 301.

But, before paging occasion arriving, access network equipment 302 receives the RRC connection request message of the transmission of terminal device 301, again with the mark S-TMSI of terminal device 301 in the request message, access network equipment 302 is to avoid UE shown in Fig. 6 A from eventually entering into Idle state and the method taken of the situation that can not carry out data transmission with network is:

Access network equipment 302 judges that whether the S-TMSI carried in the message safeguard by accessed network equipment 302, that is, judges the paging message for terminal device 301 for whether having had been received by the transmission of equipment of the core network 303 before after receiving RRC connection request message；If it is determined that having received the paging message for terminal device 301 of the transmission of equipment of the core network 303 before, it then further determines whether to send paging message to terminal device 301, i.e. access network equipment 302 carries S-TMSI from being received in the paging message paging message from equipment of the core network 303, access network equipment 302 determines the S-TMSI counterpart terminal equipment 301, access network equipment 302 judges whether the paging message for paging the terminal device 301 is waiting in turn and is sent to terminal device 301 by eating dishes without rice or wine, if the paging message etc. is to be transmitted, then access network equipment 302 abandons the paging message to be sent such as this, paging message will not be sent to terminal device 301 in corresponding paging occasion.

Furthermore, optionally, if in the RRC connection establishment process of the RRC connection request message triggering in step S901 or after the completion of RRC establishment process, access network equipment 302 receives another paging message (paging message is not the paging message mentioned in step S902) for terminal device 301 of the transmission of equipment of the core network 303, then access network equipment 302 abandons the paging message.

[optinal plan three]

Figure 11 is the flow chart of optinal plan three.As shown in figure 11, which includes the following steps:

S1101: access network equipment 302 receives the paging message for terminal device 301 that equipment of the core network 303 is sent；

S1102: whether access network equipment 302 judges whether that the RRC connection for terminal device 301 has had been established, or be in establishment process for the RRC connection of terminal device 301；If access network equipment 302 determines the RRC connection having had been established for terminal device 301, or is in establishment process for the RRC connection of terminal device 301, then the paging message (such as abandoning call terminal equipment 301) is abandoned；If access network equipment 302 determines no established RRC connection for terminal device 301, also without the ongoing RRC connection establishment process for terminal device 301, S1103 is thened follow the steps；

S1103: 302 call terminal equipment 301 of access network equipment.

Figure 12 is a kind of flow chart of possible implementation of optinal plan three.As shown in figure 12, access network equipment 302 is firstly received the RRC connection request message of the transmission of terminal device 301, it include the mark S-TMSI of terminal device 301 in the message, access network equipment 302 establishes 301 corresponding examples of the terminal device after receiving that message to safeguard relevant information (contextual information after terminal devices 301 request relevant information and terminal device 301 into connected state to enter connected state including S-TMSI etc.).

Access network equipment 302 judges whether the S-TMSI carried in the paging message is included in the established example of access network equipment 302 after the paging message for receiving the transmission of equipment of the core network 303, judge whether that the RRC connection for terminal device 301 has had been established, or during whether establishing for the RRC connection of terminal device 301.

If illustrating the just request of terminal device 301 into connected state (i.e. during RRC connection is being established) comprising the S-TMSI in example or being in connected state (having been set up the RRC connection for terminal device 301), therefore access network equipment 302 can ignore the paging message without paging the terminal device 301；Conversely, access network equipment 302 is eating dishes without rice or wine to send paging message to terminal device 301.

Optionally, in step S1102, if access network equipment 302 determines the RRC connection having had been established for terminal device 301, or it is in establishment process for the RRC connection of terminal device 301, then before the paging message for terminal device 301 that step S1101 access network equipment 302 receives that equipment of the core network 303 is sent, it may also include that the RRC connection request message for being used to establish RRC connection that 302 receiving terminal apparatus 301 of access network equipment is sent, RRC connection request message includes the mark of terminal device 301 Know；

If access network equipment 302 determined according to the mark of terminal device 301 have been received by before receiving the RRC connection request message transmission of equipment of the core network 303 for terminal device 301 another paging message (paging message is different from received paging message in step S1101) and not yet according to the paging message call terminal equipment 301, access network equipment 302 determines the discarding paging message (such as abandoning call terminal equipment 301).

In optinal plan two and optinal plan three, the situation that can not carry out data transmission with network to avoid UE shown in Fig. 6 A from eventually entering into Idle state, access network equipment 302 is handled in two kinds of situation according to the chronological order for receiving RRC connection request message and paging message, and access network equipment 302 judges to decide whether eating dishes without rice or wine to send paging message according to itself.

At present in LTE system, paging message is only received when UE is in Idle state just can initiate RRC connection establishment process to carry out data transmission with network, and the UE in connected state can ignore paging message, this, which is likely to result in, loses words.In optinal plan two and optinal plan three, the situation that can not carry out data transmission with network to avoid UE shown in Fig. 6 A from eventually entering into Idle state provides the solution of access network equipment 302, can effectively avoid situation shown in Fig. 6 A.

[optinal plan four]

Figure 13 is the flow chart of optinal plan four.As shown in figure 13, which includes the following steps:

S1301: equipment of the core network 303 receives the initial user equipment UE message for terminal device 301 that access network equipment 302 is sent, here by taking initial UE message as an example, in fact, triggering foundation is applicable for the message of the signaling connection of terminal device on any interface between access network equipment and equipment of the core network；

S1302: equipment of the core network 303 judges the S1 connection for whether having had for terminal device 301 on the interface between equipment of the core network 303 and access network equipment 302；If it is determined that having had S1 connection, S1303 is thened follow the steps；

S1303: equipment of the core network 303 discharges the S1 connection having had, and responds initial UE message, and the S1 connection for terminal device 301 is re-established on the interface between equipment of the core network 303 and access network equipment 302.

Before the UE initial message that step S1301 equipment of the core network 303 receives that access network equipment 302 is sent, further includes:

Equipment of the core network 303 receives another initial UE message that access network equipment 302 is sent, which is triggered by terminal device 301；

Equipment of the core network 303 is determining to have had S1 connection between access network equipment 302；

In step S1303, equipment of the core network 303 discharges S1 connection, comprising:

Equipment of the core network 303 sends user equipment (UE) context release command message to access network equipment 302, sends RRC connection release message to terminal device 301 for triggering access network equipment 302.

In process shown in Fig. 6 A, terminal device 301 eventually enters into Idle state and can not carry out data transmission with network.And in optinal plan four, equipment of the core network 303 can be by the judgement in step S1302, in the case where determining existing S1 connection, by executing step S1303, discharge the S1 connection connected, and S1 connection for terminal device 301 is re-established, so that the data for realizing terminal device 301 and network are transmitted.

Figure 14 is a kind of flow chart of optional implementation of optinal plan four.In Figure 14, dotted line representative paging access process, 301 active access process of solid line GC group connector equipment, using after optinal plan four, equipment of the core network 303 rebuilds S1 connection and the message flow of triggering for chain-dotted line representative.As shown in figure 14.Terminal device 301 is after sending RRC connection setup complete message, the paging message of the transmission of access network equipment 302 is received before receiving RRC Security Mode Command message, terminal device 301 is to respond the paging message to re-initiate RRC connection establishment process, access network equipment 302 receives RRC connection setup complete message and sends initial UE message to equipment of the core network 303 again in S1 interface later, equipment of the core network 303 identifies that the initial UE message that front and back receives twice is that the same terminal device 301 triggers according to the mark (S-TMSI) of the terminal device 301 carried in initial UE message.

The situation for Fig. 6 A that can not carry out data transmission with network to avoid UE shown in Fig. 6 A from eventually entering into Idle state, equipment of the core network 303 is after being received again by initial UE message, by sending the release command of UE context to access network equipment 302, discharge the S1 connection for terminal device 301 on the interface between equipment of the core network 303 and access network equipment 302 previously established, it is eating dishes without rice or wine to send RRC connection release message to terminal device 301 to trigger access network equipment 302, and equipment of the core network 303 requests to build It founds new initial context and is eating dishes without rice or wine to complete security function activation and RRC connection reconfiguration sets process with triggering terminal equipment 301, to guarantee that 302 side of access network equipment starts against the S1 connection for terminal device 301.After the completion of a series of this process, terminal device 301 reenters connected state just so as to carry out data transmission with network.

In optinal plan four, to solve the problems, such as that terminal device 301 shown in Fig. 6 A enters Idle state and can not carry out data transmission with network, in optinal plan four, equipment of the core network 303 discharges the S1 for terminal device 301 previously established after being received again by initial UE message and connects and request to establish new S1 connection for terminal device 301, guarantees that terminal device 301 reenters connected state and carries out data transmission with network.

At present in LTE system, in the case of shown in Fig. 6 A, equipment of the core network 303 identifies (S-TMSI) according to the terminal device 301 carried in the message after being received again by initial UE message and identifies that the initial UE message received twice is that the same terminal device 301 triggers, equipment of the core network 303 thinks the wrong S1 connection for terminal device 301 for just release being required previously to establish, UE context release command message is sent to access network equipment 302, RRC connection release message is sent to trigger access network equipment 302 to terminal device 301, after terminal device 301 releases RRC connection, access network equipment 302 sends the release of UE context to equipment of the core network 303 and completes (UE Context Release Com Plete) message, the release S1 connection of equipment of the core network 303 eventually lead to terminal device 301 and enter Idle state and can not carry out data transmission with network.And in optinal plan four, equipment of the core network 303 is received again by and does not require nothing more than the S1 connection for terminal device 301 that release had previously been established after initial UE message, and it requests to establish the new S1 connection for terminal device 301, process is set by sending the initial context foundation request triggering progress of access network equipment 302 RRC connection reconfiguration, RRC connection reconfiguration, which is sent, to terminal device 301 sets (RRC Connection Reconfiguration) message, and the RRC connection reconfiguration that receiving terminal apparatus 301 is sent sets completion (RRC Connection Reconfiguration Complete) message, complete reconfiguring for the RRC connection of terminal device 301, so that eventually End equipment 301 reenters connected state and carries out data transmission with network.Access network equipment 302 is after the RRC connection reconfiguration for receiving the transmission of terminal device 301 sets completion message, initial context is sent to equipment of the core network 303 and establishes completion (Initial Context Setup Complete) message, and completion has been established in instruction S1 connection.
