Abstract
A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive (MIH SWITCH, MIH SCAN) from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are sent back the MIH User entity to convey the results of the execution attempts on the requested actions, IEEE 802.21 standard (including result code).
Description
Technical field
The mobile subscriber who the present invention relates in communication system is switched.Further, disclose multilink layer resource and be used for the media independent switching processing.
Background technology
The standard that IEEE 802.21 draws up is just by exploitation so that for the exchange of the support message (i.e. 802.21 information, incident and order) between activating network and mobile node provides framework, thereby realizes seamless media independent switching (MIH).IEEE has developed execution and Management Mechanism and the process of switching between the auxiliary system for 802.21 groups.
Media independent handover (mih) functions (MIHF) is the framework that between dissimilar access networks, switches be convenient to of 802.21 definition, and helps MIH user's (like mobile subscriber, mobile node) in seamless switching, to experience more performance.MIH user is switched decision based on making from the input of MIHF.MIHF is that the function of MIH service is implemented and be used as the logic entity that is implemented in MIH user and network to treat.
Fig. 1 is the link-attached block diagram of layer between the network of the node of supporting MIH and use MIH functional entity.The mobile node 101 that is shown comprises MIHF 102, for the LLI 103 of 3GPP/3GPP2 network, for LLI entity 104 and one or more MIH user 105 of IEEE 802 networks.
MIHF 102 uses MIH local interface 115 and MIH transmission of messages 112,113 to be coupled to dissimilar Access Network (3GPP/802).MIH user 105 communicates by letter with mobile node 101 interior MIHF 102 through MIH local interface 111.MIH user is defined as the entity of the service that use provides by MIHF in 802.21; MIH user is typical policy-driven functional entity and calls MIHF and operate the low layer that is used for the relevant or irrelevant service of media.High level transmission connection 120 at the L3 layer allows MIHF102 to communicate by letter with 142 with the long-range MIHF 132 of 802 networks 131 and 3GPP network 141 respectively.When being connected to 802 networks 131, mobile node 101 can alternatively use L2 layer coffret 112 and 113, is used for management and transfer of data between functional entity 802 interfaces 104 and 134.
MIHF provides service through single media independent interface to MIH user, and MIH Service Access Point (MIH-SAP) is to make point in the protocol stack that lower-level services can use next higher-layer services.MIHF obtains service through the relevant interface of a plurality of media (the specific SAP of media) from low layer (being link layer).A kind of exemplary service that MIHF handles is a command service, and this command service is divided into two types substantially: link command and MIH order.What Fig. 2 showed is the block diagram of the protocol stack of mobile node 201, and this mobile node 201 comprises MIHF 202, and one or more MIH users 203 receive MIH order 212 to said MIHF 202 from this locality, said MIHF 202 operate in upper strata L3 or more than.Link command 211 is sent and points to low layer 204 by MIHF 202, said low layer 204 is at L2 or with lower floor and comprise for example MAC, provided for radio resources management and physical layer (PHY).Although link command 211 comes from MIHF202, on behalf of MIH user, these orders be performed.MIH order 212 produce and be sent to by MIH user MIHF 202 (for example from the upper strata mobility protocol to MIHF, or from the policy engine to MIHF).
Link command 211 uses service primitive to be performed with MIH order 212, and this service primitive is defined as abstract concept in 802.21, be used for describing the information transmission between the current layer that occurs in high-rise user and service is provided.Each service primitive is passed on one or more information parameter.As shown in Figure 2, MIHF 202 receives the MIH primitive from MIH user 203, like MIH command request 222, and determines whether it is should be triggered in order to satisfy from MIH user 203 request like one or more link layer primitive of link command request 221.Likewise, MIHF 202 can confirm shown in 231 like link command, and produce the MIH primitive towards MIH user 203 that order is confirmed shown in 232 like MIH based on receive one or more link layer primitive from low layer 204.The result of link command execution 241 reported in such affirmation primitive.
802.21 link layer primitive can directly or indirectly be mapped to the existing primitive of being supported by other link-layer technologies.In this, by the 802.21 link layer primitive described as be supposed to from " blueprint " of particular link layer technology and therefore these " blueprint " primitive and one or more relevant link layer technology (as 802.11,802.16 or even 3GPP/3GPP2) existing primitive between mapping can be established.
About command service, especially allow the order of operation link layer resource, need a kind ofly be used to carry out from MIH user's the switching command and the method for the mapping of the link command that triggers by MIHF.802.21 the early stage draft of standard provides a kind of action of ordering existing link layer to connect.Only available and order only flows to MIHF from MIH user to a link (being current link) in these action.Although exist some action of indication can be by MIHF to carry out during based on the reception of this order, but do not have the such process of standardized primitive support.Therefore, how current these processes that do not define are performed.
802.21 a plurality of MIH orders of the existing draft support of standard from MIH user to MIHF, this possibly cause that service flow is connected to another switching from a link layer.For example, exist MIH message to come the task of other particular link of order, like opening power, powered-down and change transmission and/or receiving mode.Although exist several MIH primitive to move by the trigger link layer, do not have corresponding 802.21 link layer counterparts or " blueprint " primitive, like other order, incident and information service.
802.21 the existing draft of standard (like version d 01.09) is with reference to link command, this order should be used by MIHF when the MIHF reception influences the MIH order of link layer connection, and still, these link layers orders still do not define.In addition, these existing MIH order the action that only allows the same time on a link, to take, and but are unclear need carrying out what action for the new link layer connection that the execution switching is set up.
In the draft of follow-up 802.21 standards of version d 01.09, the primitive that is called as link action (LinkAction) has no means, is used to indicate link layer to carry out the action of launching/receiving like scan chain circuit or permission/do not allow.In addition, have a kind of MIH primitive, be called the MIH conversion, during switching situation, treat the link action of carrying out in old link in order to specific instructions from " old link " to " new link ".But, the regulation of the action that this MIH conversion primitive does not allow on new link, to carry out.This primitive only also is restricted to and between two links, interacts, when needs have problem during more than two link interphase interactions.
Summary of the invention
Introduce a kind of mobile subscriber of permission simultaneously on more than a low layer media independent of command action switch (MIH) mechanism, wherein said low layer comprises medium access control system (MAC), provided for radio resources management and physics (PHY) layer.Said mobile subscriber comprises one or more MIH user function entity, MIH functional entity and networks of different type interface.Each action command and low layer link all relate to like available service on dissimilar radio access technologies (RAT) network of 3GPP/3GPP2 and IEEE 802 networks.MIH mechanism allows command link to remain connected to network and need not produce traffic carrying capacity, and the setting of the specific time of implementation of the action that allows to be asked, implements to connect at link layer.
